Land use choices will impact on ecosystem integrity, and, in the case of agriculture, particularly on the availability of water and extreme events associated with climate change. In 2006, the Merauke Regency in southern Papua was identified for agricultural development as a national food basket for Indonesia. The Merauke Integrated Food and Energy Estate (MIFEE) has caused much controversy and aggravated relationships between the stakeholders, including non-government organisations, investors, the local government, and the Indigenous People. In the contexts of such complexity, it is useful to understand the big picture and how it is perceived to impact upon different stakeholders. This integrated assessment of the sustainability of the MIFEE project makes a useful contribution to the MIFEE discourse. The Mauri Model Decision Making Framework is a unique sustainability assessment approach that enhances community understanding of complex problems. The conceptual basis of the framework is “mauri,” the binding force between spirit and substance that enables life and enhances wellbeing. The framework has been successfully applied to the assessment of the sustainability of the water supply in Agats Township in Southern Papua. The application of the Mauri Model in this foreign context was first evaluated in terms of the transferability of the framework and its suitability for use in a different international context. An extrapolation of the research findings determined that it is feasible to apply the Mauri Model in the Merauke Regency also. The objective of this research is to evaluate the sustainability of MIFEE regarding possible development scenarios and the pre-MIFEE existing condition from different stakeholder perspectives. The Mauri Model results provide a useful graphical representation of the change in “mauri” (wellbeing) caused by different options over time. The analysis clearly identifies a superior option. The decision taken to proceed with a different option indicates that the option implemented may not endure over time given the inadequate consideration of the impacts upon the Malind-Anim Indigenous Peoples. © Common Ground, Elisabeth Veronika Wambrauw and Te Kipa Kepa Brian Morgan, All Rights Reserved.

This paper examines the development and effects of a rapid livelihood transition on households, and reflects on how it fits within historic trends of livelihood change for people living in highly variable and vulnerable environments. It also discusses the implications of livelihood dynamism for local governance of natural resources. In recent decades, seaweed cultivation has expanded exponentially in coastal communities across the Asia-Pacific. A case study is presented of a remote small-island community in eastern Indonesia where over the last ten years a dramatic shift in livelihood focus has occurred. Previous dependence on diverse low-productivity livelihood activities transitioned to a predominant focus on seaweed farming. The case shows how social, economic and cultural environments co-develop as people move out of conditions of collective poverty and into more nuclear household-oriented livelihood activities. Specific attention is given to the influence on a marine resource co-management program operating on the island to illustrate how local livelihood dynamics relate to broader paradigm-driven conservation and rural development initiatives. While alternative livelihood programs seek to relieve pressure on resource stocks and provide opportunities for coastal people, this case study provides timely insights into the kinds of unintended effects, trends and impacts that are associated with rapid change in the way people make a living. This study argues that, in addition to achieving higher standards of income and well-being, livelihood improvement interventions need to adequately ensure that conditions under which new livelihood arrangements come to function can be maintained locally. © 2017 Elsevier Ltd.

This study aimed to optimize flocculation efficiency of lipid-rich marine Chlorella sp. biomass and evaluate its composition in different cultivation modes. Among three flocculants including Al3+, Mg2+ and Ca2+ tested, Al3+ was most effective for harvesting microalgal biomass. Four important parameters for flocculation were optimized through response surface methodology. The maximum flocculation efficiency in photoautotrophic culture was achieved at pH 10, flocculation time of 15min, Al3+ concentration of 2.22mM and microalgal cells of 0.47g/L. The flocculation in mixotrophic culture required lower amount of Al3+ (0.74mM) than that in photoautotrophic and heterotrophic cultures (2.22mM). The biomass harvested from mixotrophic culture contained lipid at the highest content of 42.08±0.58% followed by photoautotrophic (32.08±3.88%) and heterotrophic (30.42±1.13%) cultures. The lipid-extracted microalgal biomass residues (LMBRs) contained protein as high as 38-44% and several minerals showing their potential use as animal feed and their carbohydrate content were 16-29%. © 2015 Elsevier Ltd.

It is well known that wild game provides a significant proportion of the dietary protein of the indigenous people of the eastern half of New Guinea (PNG), but almost nothing is known of its importance in the western half (the Indonesian province of Papua or Irian Jaya). We quantified hunting effort, harvest rates and wild meat consumption and sale in the Jayapura region of north-east Papua through interviews with 147 hunters from 21 villages and meal surveys in 93 households. Ten species of mammals, seven species of birds and at least two species of reptiles were harvested in our study area, but the introduced wild pig and rusa deer were the major target species. Hunting in our study area has shifted from a purely subsistence activity towards a more commercial form at least partly due to the emergence of markets created by Indonesian transmigrants. Although the hunting of non-indigenous and certain native species might be sustainable, the maintenance of populations of large threatened species will require sensitive management. © 2012 The Author(s).

The synthesis of a macro-initiator from cellulose in mixtures of zinc-based ionic liquid and polar solvents including deep eutectic solvent, dimethylformamide, acetone, and tetrahydrofuran (THF) was studied. The results of FTIR and NMR spectroscopies indicated that the cellulose-based macro-initiator can only be obtained in an inert ether solvent, THF. When the amounts of cellulose and zinc-based ionic liquid were fixed at 0.5 g and 18 mL, respectively, the degree of substitution of the cellulose-based macro-initiator obtained was increased from 11.0% to 17.4% as the reaction temperature was increased from room temperature to 40 °C, as calculated from TGA thermograms. When the amount of cellulose was cut in half, a degree of substitution of 27.5% was achieved due to lower viscosity and better homogeneity of the reaction medium. A green, new, and relatively cheap approach has been shown to be suitable for synthesizing a cellulose-based macro-initiator.

Cassowaries are important seed dispersers in tropical rainforests of New Guinea, but little is known about their population ecology or their responses to human disturbance. We used camera traps to measure the occurrence, local abundance, and activity patterns of northern cassowaries Casuarius unappendiculatus in lowland forests near Nimbokrang, Papua, and dwarf cassowaries Casuarius bennetti in the Arfak Mountains, West Papua. Our goals were to assess human impacts on cassowaries at multiple spatial scales and to measure their activity patterns over an elevational divide. At fine spatial scales local abundance of cassowaries was strongly reduced in areas frequented by humans. At larger spatial scales the distance to the nearest village or drivable road did not affect local abundance but altered the stage structure of the individuals detected, with a higher proportion of juveniles relative to adults. Local abundance of cassowaries was unrelated to site usage by introduced pigs. Both populations studied were strongly diurnal and their activity patterns were not significantly different. Efforts to control hunting remain critical to sustaining cassowaries and the seed dispersal services they provide. Copyright © Fauna & Flora International 2015

This research objective to investigate the interaction between the bacterium E. coli with the components of the ethanol extract of herbs as a chemical library (a collection of various chemical compounds) on the nature of biological materials in the province of Papua. E. coli as a target is one of the model organisms used in new drug development (drug discovery) in this study. This model is also consistent with the research of the human genome in an effort to balance the new strategy in the diagnosis, treatment, and prevention of disease. The interaction was investigated by growing the bacteria on solid media containing ethanol extracts of herbs, herbal ethanol extract encounters with bacterial chromosomal DNA by dot blotting method and the results observed by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). On the growth of bacteria on solid media containing fungi, bacteria continue to grow so that interaction can not be observed directly, while the method of TLC increased value retention factor (Rf) of ethanol extract of herbs before and after the interaction with DNA. For the eluent composition of methanol: Water (6:4), the ethanol extract of herbs that have not diinteraksikan have Rf of 0.84 increased to 0.94 after DNA interactions. The results of the HPLC analysis provides more detailed information about the interactions that occurred with a reduction in height and broad peak at a retention time of 2.67; 12.8; and 16.9 min. This most likely indicates an interaction between the molecules of DNA with the compounds contained in the ethanol extracts of herbs.

Research related to MDR-TB have been done either to determine the nature of resistance, nucleotide sequence analysis, determining the position of a mutation in the region Mtb, phylogenetic analysis, and determination of the mechanism of drug resistance through in silico analysis of biomolecular. Due to a mutation of rpoB, particularly in the hotspot or RRDR (rifampin resistance-determining region), then RIF could not inhibit the action of RNA polymerase because it can not bind β-subunit, causing resistance to RIF. Meanwhile, INH requires activation process by the catalase-peroxidase enzyme produced by M. tuberculosis. Most of INH resistance occurs due to mutations in katG gene, the gene that produces the enzyme catalase-peroxidase, so that INH can not be converted into an active form. Currently identified katG mutations cause only resistance mutations in codon 315. A small part of INH resistance can occur because of a gene mutation InhA, ahpC and kasA, as well as other genes that correlate. Here, we reported that results of analysis performed by determining the nucleotide sequence of DNA segments using the forward and reverse primer amplification product on multiplex PCR. The primer pair amplifying the length of approximately 0.25 kb and 0.44 kb, respectively for the rpoB and katG. Primer rpoB nucleotide flanking region between 1521 and 1730, or between codons 507 and 576. Thus, a hotspot for nature resistant to rifampin or also called RRDR located between codons 507 and 533 amplify entirely. Meanwhile, the determination of the nucleotide sequence of katG segment bounded by the nucleotide sequence of 675 and 1104. This research has the potential to determine the appropriate drugs and vaccines in the future through cooperation among various fields of science: medical clinics, pharmacology, molecular biochemistry, biostatistics, and molecular microbiology.

New Guinea’s freshwater fish diversity may reach 400 species, twice the number of fish recorded in Australia. However, New Guinea’s freshwater fishes are facing rapid and poorly-planned social and economic developments, which have accelerated both habitat loss and degradation, impacting its unique biodiversity and threatening natural ecosystems. This study documents freshwater fish diversity and threats due to habitat conservation from oil palm development in the Timika Region, Papua. Fishes were sampled in canals, creeks, streams and rivers in the concession area of Pusaka Agro Lestari Company (PT. PAL) using seine and hand nets and a spear gun. Twenty two freshwater fish species in 15 families and 15 genera were recorded from the area. One of them is an endemic species of Timika (Glossamia timika), one rainbowfish species with a restricted Southern New Guinea distribution, and 12 other native fishes. Land clearing leads to increase water turbidity and sedimentation, water temperature, and pollution which are potential threats to native fishes and their habitats. The fact that PAL’s concession is part of distribution area of known distribution of G. timika in Timika vicinity, habitat conversion to palm oil elevates the threat to this species. Hopefully, PT. PAL will adopt necessary conservation measures to mitigate the potential impact during the land clearing, especially, if they leave riparian buffer regions intact to protect aquatic habitats when clearing land. © 2016, Society for Indonesian Biodiversity.

This paper proposes a Voltage Stability assessment of Power System in real time operation using Radial Basis Function Neural Network (RBF NN). One of the methods which widely used for assessing Voltage Stability is Index Stability (L-index). The indicator obtained from fundamental Kirchhoff Law which is simple in numerical calculation for steady state flow analysis. Input parameters for index calculation taken from real time measurement in the system which provides faster Recently, Phasor Measurement Units (PMUs) is a advanced method to get the information of system parameter in the wide operation with high rate data. Due to the uneconomical reason and unnecessary to place one bus for one PMU, therefore optimization placement has been applied. However, the selection of PMUs locations can be seen as a reduction of input parameters, which require for index stability calculation. To solve the lack of input parameter problem, a trained data of RBF NN has used to predict index stability. This study using 14 bus IEEE system to test the propose method and the result presents the performance of the network is sufficient to predict the index stability. © 2011 IEEE.
