The Bandung Institute of Technology or Institute of Technology, Bandung is a state, coeducational research university located in Bandung, Indonesia. Established in 1920, ITB is the oldest technology-oriented university in Indonesia.ITB was considered the top choice among Indonesia's high school students in 2006 and has been credited as one of the most "prestigious" universities in Indonesia, together with University of Indonesia, and Gadjah Mada University.Sukarno, the first president of the Republic of Indonesia, earned his engineering degree in civil engineering from ITB. B. J. Habibie, the third president of Indonesia also graduated from ITB.The university cultivates professional and social activities by supporting its students' unions, the student government councils that exist in every department. Each students' union has its own distinctly designed jacket that, among other traditions, serves as part of its member identity. There are also a number of student activity units/clubs supporting ITB student interests in rounding out their educational experience. It is not uncommon that the students and alumni are identified by the clubs to which they belong at ITB, in addition to their class year and major.The university is a member of LAOTSE, an international network of leading universities in Europe and Asia exchanging students and senior scholars.Until 2012, ITB had four study programs internationally accredited from an independent U.S. accrediting institution, ABET, where ITB is the only public university in Indonesia, with this particular international accrediting institution. The four study programs are Ocean Engineering, Electrical Engineering, Chemical Engineering, and Engineering Physics.ITB's march "Mars ITB" and hymn "Hymne ITB" were arranged by a former professor, Prof. Dr. Sudjoko Danoesoebrata.

JAKARTA, Indonesia, May 12, 2017 /PRNewswire/ -- Xirka Silicon Technology today unveiled the launch of Chipset SCard XCT136, the first local Indonesian smart card, providing multi-function purposes for student identity cards. To track student attendance, it works by using computerized fingerprint scanners to ensure a secure environment. It also offers a cashless transaction option, so all transactions related to university activities can be done by swiping the card. Supported by Indonesian Ministry of Research, Technology, and Higher Education together with Indonesian Ministry of Communication and Informatics, the chipset currently targets educational institutions, such as University of Indonesia, Bandung Institute of Technology, Hasanuddin University, and Telkom University, and is widely applied to electronic student identity cards. "The digital economy has a tremendous potential in advancing the Indonesian economy. This sector will contribute up to 11% of economic development in 2020. If accomplished, in 2030 Indonesia will occupy the 8th position in the world economy. Therefore, it needs greater innovation to face global competitiveness and this chipset development is the answer," said Rudiantara, Minister of Communication and Information Technology of the Republic of Indonesia at the launch ceremony of Chipset SCard XCT 136 on May 12th 2017. Through Industrial Technology Development Program and Technology Innovation Program, Ministry of Research, Technology, and Higher Education of the Republic of Indonesia initiated the product development, involving students from state universities in Indonesia. By participating in the development process, the students are given the opportunity to showcase their ability to create and innovate, among their peers. According to research from MARS Indonesia, in 2016, state universities in Indonesia had a total of 507,000 new students. "Therefore, to answer market needs, Xirka Silicon Technology will provide up to 1 million units of Chipset SCard XCT136 per year for those universities," said Sylvia W. Sumarlin, President Director of PT Xirka Silicon Technology. Research and production of each component of the chipset are carried out domestically in Bandung, West Java, ensuring security against data breaches and fraud from cybercriminals. The exclusive production of chipset components in Indonesia has been successful so far in preventing other countries from gaining access or gathering information about the design and architecture of these detailed components. "It ensures data confidentiality, since no other regions will have any access to its design without Xirka's permission," added Sylvia. Xirka Silicon Technology started producing chipsets in 2007 and entered into the wider APAC regional market by partnering with Siltera-Malaysia, Singapore, Taiwan, and Japan. They won the first prize at Asia Pacific ICT Alliance Award 2008 (APICTA) for the development of WiMAX baseband chipset. In 2016, Xirka Silicon Technology completed development of its local smart card protocol, which includes Key Management System, Card Management System, and Smart Card Operating System allowing for support of multi-application features. According to Sylvia, the chipset provides several blocks of data storage memory. "Each offers different functions, such as application ID, payment, and loyalty card. Early next year, Xirka plans to launch Near-Field Communication (NFC) chipsets, which is commonly used for electronic ticket and mobile payment." Together, Xirka Silicon Technology and Microelectronics Center Bandung Institute of Technology worked to optimize security and data storage by strengthening technologies in all support systems, including card reader portable, virtual Secure Access Module (SAM), secure network, and card database. In security optimization, Chipset SCard XCT136 utilizes security engine DES and 3DES, adding 136 Kbyte to the chipsets to support more extensive data saving. Xirka Silicon Technology is a fabless company that focuses on the development of WiMAX baseband chipsets. Established in May, 2007, it delivers a System-on-Chip (SoC) for Broadband Wireless Access (BWA) to fulfill businesses needs, supporting everybody's dynamic lifestyle which very often requires immediate attention and action. To provide assurance, our SoC uses IEEE 802.16d-2004 standard for nomadic WiMAX and IEEE 802.16e-2005 for mobile WiMAX. Continuing its commitment as a design company, since 2011 Xirka has developed SIM cards and proceeded with smart card products and derivatives such as access cards, ID cards and secured cards for banking by utilizing Near Field Communication (NFC) and RFID technologies. A lot of IT equipment will benefit from Xirka's chipset, such as, modem cards, computers, notebooks, mobile gadgets, CPE modems, etc. Xirka also recognizes the need of our clients to have a reliable chipset at an affordable price, therefore we have built our research and design center and developed products with clients' concerns on our mind.

Over the last century, the world has become increasingly dependent on oil as its main source of chemicals and energy. Driven largely by the strong economic growth of India and China, demand for oil is expected to increase significantly in the coming years. This growth in demand, combined with diminishing reserves, will require the development of new, sustainable sources for fuels and bulk chemicals. Biomass is the most attractive alternative feedstock, as it is the only widely available carbon source apart from oil and coal. It was recently found that direct parental administration of SMF to mice leads to abundant acute necrosis and proteinaceous casts in the proximal tubules as the dominating toxicological effect. Additional research provided evidence for the involvement of organic anion transporters in the renal accumulation of SMF. These transport characteristics could be responsible for the selective damage of renal proximal tubules by this reactive metabolite.

Over the last decade, the European Grid Infrastructure (EGI) has built a distributed computing and data infrastructure to support over 21,000 researchers from many disciplines with unprecedented data analysis capabilities. EGI builds on the European and national investments and relies on the expertise of EGI.eu - a not-for-profit foundation that provides coordination to the EGI Community, including user groups, EGI.eu participants in the EGI Council, and the other collaborating partners. The mission of EGI-Engage is to accelerate the implementation of the Open Science Commons vision, where researchers from all disciplines have easy and open access to the innovative digital services, data, knowledge and expertise they need for their work. The Open Science Commons is grounded on three pillars: the e-Infrastructure Commons, an ecosystem of key services; the Open Data Commons, where any researcher can access, use and reuse data; and the Knowledge Commons, in which communities have shared ownership of knowledge and participate in the co-development of software and are technically supported to exploit state-of-the-art digital services. EGI-Engage will expand the capabilities offered to scientists (e.g. improved cloud or data services) and the spectrum of its user base by engaging with large Research Infrastructures (RIs), the long-tail of science and industry/SMEs. The main engagement instrument will be a network of eight Competence Centres, where National Grid Initiatives (NGIs), user communities, technology and service providers will join forces to collect requirements, integrate community-specific applications into state-of-the-art services, foster interoperability across e-Infrastructures, and evolve services through a user-centric development model. The project will also coordinate the NGI efforts to support the long-tail of science by developing ad hoc access policies and by providing services and resources that will lower barriers and learning curves.

Scientific research is no longer conducted within national boundaries and is becoming increasing dependent on the large-scale analysis of data, generated from instruments or computer simulations housed in trans-national facilities, by using e Infrastructure (distributed computing and storage resources linked by high-performance networks).\nThe 48 month EGI-InSPIRE project will continue the transition to a sustainable pan-European e-Infrastructure started in EGEE-III. It will sustain support for Grids of high-performance and high-throughput computing resources, while seeking to integrate new Distributed Computing Infrastructures (DCIs), i.e. Clouds, SuperComputing, Desktop Grids, etc., as they are required by the European user community. It will establish a central coordinating organisation, EGI.eu, and support the staff throughout Europe necessary to integrate and interoperate individual national grid infrastructures. EGI.eu will provide a coordinating hub for European DCIs, working to bring existing technologies into a single integrated persistent production infrastructure for researchers within the European Research Area.\nEGI-InSPIRE will collect requirements and provide user-support for the current and new (e.g. ESFRI) users. Support will also be given for the current heavy users as they move their critical services and tools from a central support model to ones driven by their own individual communities. The project will define, verify and integrate within the Unified Middleware Distribution, the middleware from external providers needed to access the e-Infrastructure. The operational tools will be extended by the project to support a national operational deployment model, include new DCI technologies in the production infrastructure and the associated accounting information to help define EGIs future revenue model.
News Article | November 22, 2016
With her hand stretched upward, the elderly storekeeper in batik dress and white headscarf indicates the height of the waters that poured into her home in Jakarta’s great flood of 2007. Sukaesih is a diminutive figure, but she points to a ridge on the doorframe about two metres above the threshold. The 60-year-old grandmother, who like many Indonesians goes by only one name, lives in the down-at-heel waterfront neighbourhood of Muara Baru. Her front room-turned-store, where she sells soft drinks and the clove kretek cigarettes beloved of locals, looks unassuming, but is at ground zero for the city’s battle for survival. Just across the alleyway is the stone seawall that was reinforced and heightened after 2007, but is already cracking, buckling and leaking. The fortification is all that stands between these homes and the waters of Jakarta Bay, which lap just beneath the rim on the other side. Filthy water already seeps through the cracks continuously, leaving streams of muddy run-off flowing in front of Sukaesih’s shop. When tides are high, the water pours over. “We live with this reality every day,” Sukaesih says, looking out at the embankment. “Water comes in through the wall all the time, and it comes over the top whenever there’s a high tide.” The biggest problem, however, is that the seawall itself – the only thing protecting Sukaesih’s community from inundation – is sinking. Forget Venice, which is slowly dropping into its watery foundations at an estimated rate of 2mm per year. That’s a drop in the ocean compared to Indonesia’s capital, particularly its northern belt, where four million people live in neighbourhoods that are now up to four metres below sea level. Areas of north Jakarta, including the seawall designed to protect them, are sinking at an estimated 25cm a year. “I have been here since 1981 but I don’t know how long we can stay. The water gets higher every year,” Sukaesih says – referring to the danger that is, in fact, posed by the ground sinking beneath her feet. Jakarta is sinking because of subsidence. The city does not pipe in enough drinkable water, so Jakartans rely largely on wells which extract water from shallow aquifers. The result: the land above it collapses. The problem is exacerbated by the explosion of new apartment blocks, shopping malls and even government offices, which – despite official restrictions on groundwater extraction – not only draw water from this porous ground but also add to the weight compacting it. The concretisation of Jakarta has also led to increased run-off, making flooding worse while not replenishing the ground water supplies. As the sinking continues at a rate unparalleled in any other urban area in the world, the danger of a catastrophic flood grows, caused not by devastating seawater surges or storms – but by monsoon rain-swollen rivers bursting their banks because gravity no longer helps them flow out into the bay. There is a desperate need to supply potable water to the city from reservoirs to the east and west. But while plans for pipelines remain in the pipeline, some experts claim Jakarta is careening towards the point of no return. Set in a basin of low-lying plains criss-crossed by 13 rivers, Jakarta – home to 10 million, with a total of 30 million living in the sprawl of Greater Jakarta – owes its existence to its waterfront location and geography. The natural harbour was for several centuries an important port for its Hindu and then Muslim rulers, before Dutch settlers seized control and established the trading post of Batavia as capital of their East Indies territories. The perils of flooding are as old as the city. The Dutch, the masters of such challenges at home, built a network of canals in an attempt to control the flow of waters, but never mastered them. Now, as the city sinks so dramatically, Dutch engineers and businessmen are again offering their proposals to defeat encroaching waters and reclaim land. “We all knew that Jakarta was sinking back in the 90s and indeed earlier, but nobody was that worried or really had any idea of the extent,” says JanJaap Brinkman, a hydrologist with the Dutch research institute Deltares, who has spent most of his adult life working on Jakarta’s watery woes. “Then came the floods in 2007. When we studied the data and looked at the mapping, we discovered the city was sinking not perhaps by a centimetre or so per year, as had previously been thought, but by 5-10cm on average, and much more in places.” With more than 50 people dead and 300,000 forced to evacuate their homes as waters covered more than a third of the city, 2007 was a startling wake-up call. The solution on paper was simple – the city must supply clean piped water, and end its dependency on groundwater extraction. Tokyo did just that in the 1960s after sinking more than four metres during the 20th century. Within a decade, says Brinkman, pointing to graphs on his laptop, that downward trajectory was permanently halted. But in Jakarta, there has been no significant progress in the nine years after the floods, thanks to a combination of financial restraints, competing infrastructure demands, and the sclerotic impact of the highly decentralised system of government introduced in response to the Suharto dictatorship. Brinkman, his good humour at times tested by this inertia, says there are now only two years left to act, or it will be too late to save northern Jakarta from disaster. There is another dramatic and controversial plan to save the world’s fastest-sinking city from itself: the so-called Giant Sea Wall and Great Garuda projects. At the heart of the proposals – with an estimated cost of as much as $40 billion – is a massive dike arcing 25 miles across Jakarta Bay which would create a vast manmade lagoon, with a new coastal megacity to be built around it on reclaimed land. The project, officially known as the National Capital Integrated Coastal Development (NCICD) programme, was backed with aid from the Dutch government, embraced by Indonesia’s president Joko Widodo, a former governor of Jakarta, and is now being championed by a Dutch-led consortium. The land reclamation dates back to a stalled plan from the President Suharto era to create 17 new islets off the city’s coastline. But it has morphed into a much more ambitious concept for a colossal new waterfront city, fanning out from sea wall in the shape of a garuda – the mythical bird of Hindu origin that is the country’s national symbol – with a multilane ring road for the perennially traffic-clogged capital running along its rim. From above, the designers’ illustrations for the Great Garuda project are redolent of the artificial Palm islands off the shore of Dubai. Its prospective developers also looked closer to home for inspiration, planning to build glitzy skyscrapers, luxury flats, shopping malls and attractions similar to Singapore’s Sentosa Island. Champions say the Giant Sea Wall will soon be the only way to save the city from catastrophic floods sweeping across the northern belt of land, with the new islands providing the financing by tapping into the monies of property development tycoons. But the schemes are now mired in lawsuits, scandals and moral controversy – particularly over the mass evictions of traditional fishing villages and waterfront communities, many of which have been bulldozed flat. Critics – a broad coalition of Indonesian scientists, land activists and local residents – say it is an outlandish and unnecessary project that would wreak environmental and social disaster. They argue the lives of traditional fishing communities are being destroyed as mass evictions are imposed, with whole neighbourhoods razed and residents relocated more than 10 miles away. They also claim that walling off the bay would turn it into a “septic lagoon” of trapped freshwater. With little sewage treatment for the river water pouring into the bay, this corporate attempt to “sanitise” Jakarta’s waterfront could end up having exactly the opposite effect. What is not in dispute is the need for urgent action. Just in front of the old fortification at Muara Baru, thick new pilings are being driven into the seafloor to provide a higher and stronger defence against the waters. Few people object to this, the start of Phase A of NCICD programme. “This is the ‘no regrets’ stage, as everyone agrees that we need to do this now,” says Tuty Kusumawati, head of the Jakarta planning department, as she pores over maps and diagrams of the waterfront. To deal with the freshwater flooding, heavily polluted and rubbish-strewn rivers are being widened, dredged, cleaned and protected with new concrete barriers, in initiatives ordered by Basuki Tjahaja Purnama, the governor known to all by his nickname, Ahok. For the smaller rivers that have already sunk too far to flow out to sea, pumping stations and polders are being built, with reservoirs to hold water at times of heavy rain and flooding. But some experts say there aren’t large enough pumps or sufficient land available to deal with the larger rivers – hence the call for more dramatic intervention. When presented with the proposal for the Giant Sea Wall, the Indonesian government asked the Dutch consultants to deliver a more ambitious concept to accompany it. From that request, the design for the Great Garuda was born. The Netherlands is an undisputed bastion of international expertise on fighting the seas and land reclamation. But in its former colony, some critics have expressed scepticism about the motives of the Dutch government-funded consultants and businessmen proposing such a colossal scheme. Victor Coenen, the project manager for Witteveen+Bos, the engineering consultancy that heads the Giant Sea Wall consortium, shrugs off the criticism. “Fine, if they don’t want our help, then we can go elsewhere,” he says. “But it is the Indonesian government that has asked for Dutch assistance to deal with the flooding, and it is Dutch government money that is helping.” This week’s visit to Indonesia by a high-profile Dutch trade mission, headed by the prime minister, Mark Rutte, is giving fresh impetus to the debate. The Save the Jakarta Bay Coalition, an alliance of groups opposed to the scheme, has written to Rutte spelling outs their fears and criticisms. “The Dutch are well known for their flood mitigation measures,” the letter notes. “These measures adopt a complex approach, which follows the principles of environmental and social protection and good governance. [But] what is happening in Indonesia is entirely the opposite. We are deeply concerned about the livelihood loss and infringement of human rights, as well as irreparable environmental damage, caused by the project. “We therefore stress that, if your government and the Indonesian government insist on building the NCICD, tens of thousands of people connected to small-scale fisheries will lose their livelihood.” The widening and fortification of the city’s rivers has already seen the eviction of thousands from kampung communities that have sprung up along its rivers and reservoirs. Bulldozers are often deployed with just a few days notice and residents ordered to move to new concrete public housing, often miles away from the waterfront where they work. According to Brinkman, however, “There are only two options, retreat or advance. We either abandon and evacuate north Jakarta, which is a non-starter, or we advance out into the bay with the seawall.” At Muara Baru, Coenen outlines the arguments for NCICD’s Phase B – the Giant Sea Wall – as he conducts a tour of the current fortifications. “In the old days, the water ran out to sea,” he says. “Now water collects in the city from several of these rivers. It can’t get out so we pump it out. But for the large rivers, we need ever-higher riverbanks and ever-bigger pumping stations and storage lakes. “We can’t build up riverbanks that are five or seven metres above the neighbouring communities, and there is not enough space onshore for the pumping lakes. So we’re proposing the Giant Sea Wall to create what is effectively a giant pumping lake offshore. Then we can then lower the water level, so those rivers can flow again.” But this part of the project has been met with scepticism by some prominent Indonesian scientists. Alan Koropitan, professor of oceanography at Bogor Agricultural University, contends the solution for Jakarta Bay is “restoration, not reclamation”. He says building an outer sea wall and manmade islands would create greater pollution and sedimentation as waters are trapped inside the dike, rather than being flushed out to sea. “If, instead, we can restore the bay and its polluted waters, that would mean something good for civilisation in Indonesia. I believe that a new economy will come from that – in tourism, aquaculture and fisheries.” Muslim Muin, head of coastal engineering research at the Bandung Institute of Technology, is equally unimpressed with the multibillion-dollar proposal. “If the Giant Sea Wall is built, it would inflict huge construction and operational costs and serious environmental costs. Even worse, it would exacerbate Jakarta’s flood risk. “By building the reservoir, the circulation of water will drastically decrease and even reach a point when it becomes stagnant water. The natural cleansing process would no longer happen,” he adds, citing the water-borne malarial epidemics of Dutch days. Coenen too acknowledges the environmental dangers of a “septic lagoon” that could be created by walling off the bay. But he contends that the wall should be accompanied by measures such as water sanitation. “The point really is that very soon, we will have no choice,” he adds. It is not just an environmental controversy, however. The Giant Sea Wall plans have become entwined with ever-more ambitious, and contentious, schemes for a radical facelift for the whole waterfront. The residential move south away from Jakarta’s coast began with Dutch colonialists in the 19th century, who preferred to live in greener areas less prone to disease and flooding. It was a trend that continued after independence in 1945, with most Indonesians choosing to live in what is now South, East and West Jakarta. That left behind a coastline dominated by the city’s industrial port and harbour, and populated by fishermen’s slum dwellings. The notable exception was the Indonesian-Chinese community that plays a powerful role in the country’s business world, including property development. The city’s ethnic Chinese have long lived near the bay and many influential families are based there in exclusive gated communities and nautical-themed luxury apartment blocks bearing names such as Regatta and Green City. Talk of a new waterfront city of 17 manmade islets, jutting up to two miles out into the bay, began in the mid-1990s. The project stalled after the Asian economic crisis but was later revived with an added twist – it could be deployed to garner private funding for the NCICD in a country where government coffers are always stretched. Huge industrial dredgers moved into the bay to discharge their loads and start creating the first four islands in 2013, but that work was brought to a jarring halt last April. A moratorium was declared in the wake of a high-profile and ongoing corruption case involving a company executive from one of the showpiece developments bribing a local parliamentarian over zoning laws. The prosecutions exposed murky financial ties between the developers and Jakarta city budgets. The government said the reclamation would start again in September, but as yet there has been no more work on the scheme. So the four part-built islands sit in Jakarta Bay, unfinished and off-limits. Visitors entering the air-conditioned oasis of the Riverwalk Bay shopping mall, at the base of the Green City complex in the waterfront Pluit district, can cast their eye over a model (pictured above) of how the NCICD’s “Island G” – marketed as Pluit City – looks in the designers’ eyes. It is a futuristic extravaganza of gleaming modernist high-rises, gated villa compounds and yacht marinas. A security guard hovers to enforce the “no photographs” rule, so for a close-up view of Island G, it is necessary to head out into the bay with Suhali bin Urip, a local fisherman who has worked these waters for 30 years. The 58-year-old Suhali – his face creased beyond his years by decades at sea under the tropical sun – is a prominent voice in the “no reclamation” campaign. “We’re the ones who live and work here, but nobody is consulting us about our futures,” he says. “The elite, the politicians and the rich, are making the decisions, but they don’t care about us or understand us.” Suhali lives with his family in the fishing village of Muara Angke, where men make on average $25 to $40 a month working on boats that are now forced to venture ever-further out to sea in search of a catch. Shanty dwellings of plywood, breeze blocks and corrugated metal, often lashed together by rope or metal fixtures furnished from scrap, are precariously balanced on wooden stilts over a waterfront that serves as toilet and rubbish dump. Suhali’s small wooden skiff, its paint peeling and decking loose, is tethered at the end of a rickety path of bamboo poles and old door frames. He yanks a few times on the starting cord of the outboard engine, and we sputter off into the bay towards our target – our progress in these sensitive waters observed by a police motorboat. The future Pluit City soon comes into view, although for now the islet is no more than a low spit of reclaimed sand sitting a few feet above water level, with the Regatta and Green City developments looming on the skyline behind it. “I used to fish just here,” Suhali says, his tiny boat bobbing offshore. “But now they are building this land in our waters, there are no fish left to catch here.” During our trip, we encounter only one fisherman casting his nets – as much in hope as expectation of a catch. The only other person working out here is a scavenger in a rowing boat, collecting washed-up plastic products to sell for recycling. In ongoing lawsuits objecting to the island reclamation scheme, the Jakarta Legal Aid association has argued these new islands are occupying traditional fishing grounds, while the sediment and dredging work have driven away fish from the remaining waters. Back onshore, the pervasive smell of salted fish, boiled first over open furnaces, then laid out to dry in the tropical heat, wafts across from nearby processing warehouses. “Our family has been working here for three generations, but you can be sure they won’t want us here if they go ahead with these grand plans,” says Haji Hernoto, 44. “They won’t like the smell or the sight of us.” Asked who “they” are, his wife Sitiwardah adds: “Oh you know, the rich, the politicians, the developers … The Chinese who are going to buy these apartments.” Her comments reflect resentment and division not just over class and money, but also ethnicity. The waterfront developers are nearly all Chinese-Indonesians – as is Ahok, the blunt-speaking governor – while the local communities facing displacement are overwhelmingly Indonesian Muslims. Furthermore, the swanky new developments planned for the manmade islands are being marketed not just at affluent Indonesians but, with a particular thrust, at overseas Chinese buyers from Singapore, Malaysia, Hong Kong and mainland China, via aspirational television advertising that gushes in Mandarin about the vision of a “new lifestyle” in Pluit City. While the battle over the shape of Jakarta’s seafront is still being waged, its governor is already making his mark with controversial measures to tackle flooding challenges inland. The city’s rivers have long been throttled by both rubbish and people. Tens of thousands of Jakartans set up home near and beside water, sometimes building out on stilts. These unofficial kampungs developed into thriving, if dirt-poor, communities where people live and work. Some residents used the water to dump their rubbish and their sewage, resulting in a foul-smelling, insanitary and unsightly network of rivers and canals that also contributed to the city’s chronic floods, as their waters could not drain properly and their flow was narrowed by the encroachment of homes and factories. Of course, many other Jakartans also contributed to the pollution problem, but it was these impoverished kampung that took the official blame. Ahok deployed squadrons of workers to clean the rivers of their choking surface carpets of rubbish and water hyacinths. It is one of several “quality of life” initiatives that also include establishing a city hotline that locals can call to report problems. But in the governor’s brusque, “get it done” approach to city planning, he has also overseen mass evictions from overcrowded waterside kampung. Officials said the location of homes on the edge of waterways compounded flooding risks, while the residents were in direct danger from the inundations. Ahok has followed advice from consultants to widen and raise the rivers and install levees, so that storm-swollen waters can flow out to sea or be stored safely. Across Jakarta, such concrete slabs are being put in place in riverbanks by heavy-lifting equipment. At City Hall, Kusumawati, the planning chief, outlines the plans for rehousing residents from riversides, as well as detailed projects to employ fishing communities displaced from the seafront. “We are looking after our citizens,” she says. “These new homes are better than the slums where many have lived.” Coenen, meanwhile, offers a blunt assessment of the challenge facing Jakarta. “It’s unfortunate, but you have to destroy some areas to save the city,” he says. “These are technical solutions to technical problems. But the city also needs social solutions to social problems.” His words are of no comfort to residents of areas such as the Akuarium neighbourhood, near the old Sunda Kelapa harbour at the mouth of the Ciliwung river. Hundreds of homes, including some not next to the water, were demolished here earlier this year as residents and security forces clashed. Today, Akuarium resembles a scene from a wartime blitz. Many locals are still squatting among the debris, while some are rebuilding homes from salvaged metal and brick on the ruins of their old ones. The suspicion is widespread that they were evicted to make way for tourist projects in an area near old red-tiled Dutch buildings of the colonial era, rather than to keep rivers flowing and combat flooding. Officials have told evictees to move to subsidised apartments in low-cost, concrete public housing blocks that are being built across the city. But the new housing offered to some slum residents is up to 12 miles away, in locations that would take the people of Akuarium far away from the waters where they work in the fishery and tourism businesses. “We’ve been offered no compensation, despite their promises, and were told we must move to new apartment buildings in Cakung,” says Johariah, a mother-of-10, referring to a district far inland. Johariah ekes out a living to support her family by selling salted fish. Others living amid the debris tell a similar story; that they rely on being close to the water. The abrupt manner of the house clearances, with bulldozer squads dispatched along with armed police protection after only a few hours’ notice, has deepened the anger – as have rows over ownership and compensation. The authorities describe these kampung residents as squatters on government land. But many have lived here for years, even decades, and insist their right to residence was approved by city agencies that levied annual property taxes. Some angrily wave their tax bills; others say they bought their homes and even received bank loans for them. “They say we did not have the right to be here, but I paid for my home,” says Johariah. “You can’t treat us like this.” Graffiti denouncing Ahok – as he is known to friend and foe alike – is daubed across the walls here. Islamist parties have capitalised on the outrage to fuel their campaign against the governor, who is the most prominent Christian in the world’s most populous Muslim nation, and enjoys high popularity ratings in much of the city. Last week, police named him as a criminal suspect in a blasphemy investigation, for an aside he made about his political opponents citing the Koran. The governor, who is running for re-election in February, now faces prosecution on charges that can carry up to five years in jail. The case is expected further to complicate Jakarta’s waterfront facelift plans. For now, reclamation work on the 17 islets remains on hold, amid reported splits within the president’s cabinet – although Jokowi’s support is expected to win the day. It is telling that Luhut Pandjaitan, the co-ordinating maritime minister and a close confidant of the president, has insisted the moratorium will be lifted. “There is no reason for us not to continue with the reclamation of the North Jakarta coast,” he said in September. “It is estimated that all of North Jakarta will sink below sea level by 2030,” the president himself said at a cabinet meeting earlier this year. “Because of that, the development of the capital’s seaside, which has been delayed for so long, is the answer for Jakarta.” But a follow-up cabinet session, expected to take place in late October to confirm the government’s position on the NCICD, did not materialise. In the always opaque world of Indonesian politics, the power battles behind the scenes remain hidden. There is now speculation that the decision on the Giant Sea Wall will be delayed for a year or more, allowing time for further investigations into the impact on the environment and the people of the seafront. The Great Garuda development that was supposed to take flight from that dike could be grounded even longer. Back in the ruins of Akuarium, as Johariah surveys the scene from her makeshift fish stand, local tour guides lead European visitors through the rubble, en route from the nearby maritime museum to the boat dock for the old harbour. It is a jarring juxtaposition in the struggle over Jakarta’s waterfront future. And all the time, as the view of the crumbling seawall from Sukaesih’s shopfront shows all too clearly, this city is still sinking. Do you live in Jakarta?

Organometal halide perovskite-based solar cells have recently realized large conversion efficiency over 15% showing great promise for a new large scale cost-competitive photovoltaic technology. Using impedance spectroscopy measurements we are able to separate the physical parameters of carrier transport and recombination in working devices of the two principal morphologies and compositions of perovskite solar cells, viz. compact thin films of CH 3NH3PbI3-xClx and CH 3NH3PbI3 infiltrated on nanostructured TiO 2. The results show nearly identical spectral characteristics indicating a unique photovoltaic operating mechanism that provides long diffusion lengths (1 μm). Carrier conductivity in both devices is closely matched, so that the most significant differences in performance are attributed to recombination rates. These results highlight the central role of the CH 3NH3PbX3 semiconductor absorber in carrier collection and provide a new tool for improved optimization of perovskite solar cells. We report for the first time a measurement of the diffusion length in a nanostructured perovskite solar cell. © 2014 American Chemical Society.
