We model postseismic changes to the shoreline of West Aceh, Indonesia, a region largely affected by the December 2004 Sumatra-Andaman earthquake and ensuing Indian Ocean tsunami, using a cross-shore morphodynamic model. Subsidence of 0.5–1.0 m and tsunami scouring during the 2004 event caused the complete destruction of the beach and the landward displacement of the western coast of Aceh by an average of 110 m. Comparing a series of satellite images and topographic surveys, we reconstruct the build-up of a new beach ridge along a 6 km long stretch of coastline in the years following the event. We then use the cross-shore model UNIBEST-TC developed for a wave-dominated sandy shoreline to determine the controlling factors of shoreline recovery. Input parameters include bathymetric data measured in 2015, grain size characteristics of offshore sediment samples, modeled wave data, tidal elevations from a nearby tide-gauge station as well as measured and modeled postseismic uplift data. After establishing a cross-shore profile in equilibrium with the prevailing hydrodynamic conditions, we simulate the post-tsunami recovery, the effect of the monsoon seasons, as well as the influence of postseismic land level changes for up to 10 years and compare them to the observed coastal development. Our modeling results indicate that the recovery of the western Acehnese shoreline after the 2004 tsunami was quick with littoral sediment transport normalizing to pre-tsunami conditions within two to four years following the event. However, field data shows that the shoreline stabilized 50–90 m landward of its pre-2004 tsunami position, most likely due to the build-up of a prominent higher beach ridge in response to coseismic subsidence. Observed variability in shoreline position in the order of a few tens of meters since 2009 can be attributed to seasonal wave climate variability related to the monsoon cycle. The effect of postseismic uplift on shoreline position is small and in the order of only a few meters over 10 years, which is 3 to 5 times smaller than long-term coastal progradation rates that are driven by abundant sediment supply to the littoral zone. This overall progradational trend will promote preservation of seismically modified beach ridges, which can serve as paleoseismic indicators. © 2017 Elsevier B.V.

The Acehnese mahseer, locally known as keureling, Tor tambra is one of the highest economically valued freshwater fishes found in Aceh waters. The culture of T. tambra was initiated in Aceh Province, Indonesia more than five years ago. However, the growth rate in captivity has been low, probably due to feeding problems. Hence, the objective of the present study was to evaluate the optimum level of dietary protein in commercial feeds for growth improvement. Three commercial feeds with different levels of protein i.e. 20%, 25%, and 30%, were tested in this study. A total of nine semi-concrete ponds were used and each pond was stocked with 15 mahseer fingerlings. The experimental fish were fed at a ratio of 3% of body weight twice a day for 60 days. The ANOVA tests revealed that dietary protein levels significantly affected growth performance, protein efficiency ratio, protein retention efficiency and lipid content in carcass but did not significantly affect survival rate and protein content in the carcass (p>0.05). The results showed that the growth performance, survival rate, and protein content increased with increasing protein level in the diet and the best composition was 30% of protein.

Background: Indonesia has the third-highest number of deformity cases caused by Leprosy after India and Brazil. In 2015, there were 23 cases in Nagan Raya District, Aceh Province, Indonesia, 15 of them were categorized as leprosy disabilities, associated to the self-care group “Payoeng Meureuleuy.” This study aimed to determine the strategy in decreasing the effect of leprosy deformity through self-care group “Payoeng Meureuleuy” in Tripa Makmur Sub-District, Nagan Raya Regency. Method: This study was a qualitative research, by observing, guiding, and interviewing leprosy suspects in six months, from October 4th to April 15th. The population of this study was all patients with leprosy recorded in the medical records of Nagan Raya Health Office, Aceh Province, in 2015. Results: The results showed that family support, personal hygiene, group support, changing stigma, and leprosy disabilities care increased by implementing the guidance strategy during six months through the self-care group “Payoeng Meureuleuy” in Tripa Makmur Sub-District, Nagan Raya Regency. Conclusion: It is recommended that the medical staff develop many self-care groups for continuous guidance on leprosy deformity suspects. Additionally, comprehensive knowledge to the family in dealing with leprosy, support and motivation in practicing self-care are needed. © 2017 American Scientific Publishers All rights reserved.

Coastal plant locally known as terong pungo (Solanum sp.) was used by Aceh community as traditional medicine for toothache. The objectives of this study were to isolate endophytic fungi from the leaves of terong pungo and determine the antibacterial activity of the fungi against bacteria causing dental caries and infection. Eight endophytic fungi were isolated. Antagonism test among the isolates was performed to select the most dominant fungus. TP6 was the selected fungus based on the antagonism assay. Crude extracts of the fungus were macerated from the culture broth using ethyl acetate. The strongest antibacterial activity of the extracts was obtained when the fungus was at 12 days of cultivation. The fungal crude extract was strongly active against Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa with inhibition zone diameter of 20, 21 and 23 mm, respectively.

The objective of this study was to assess the ability of artificial aggregating substrates for fish and squid eggs attachment. This study was performed in an area adjacent to Bidong Island on the East Coast of Peninsular Malaysia. The aggregating devices were set up at three different water depths (6 m, 12 m and 18 m) in nine locations. The presence of fish eggs and squid eggs in attractors were collected every two weeks. Scuba diving was used to collect data in different water depths. This study revealed that no fish eggs were recorded on the attractors, but there was a presence of squid eggs in seven locations. In addition, the results also showed that environmental factors such as temperature, salinity, pH and dissolved oxygen (DO) not significantly affect the presence of squid eggs. However, the location and depth of the attractors from the water surface have a significant effect on squid egg attachment in atractor. © 2015, BIOFLUX SRL. All rights reserved

Aceh province located at the northwestern tip of Sumatra Island in Indonesia has a coastal environment and a coastline of around 1660 km. Banda Aceh, Aceh Besar, and Aceh Barat are among the districts of Aceh Province located on those coastlines. The earthquake and tsunami that struck Aceh in December 2004 caused much of these districts to be submerged by seawater. Thus, the environment of these areas might become more corrosive. This study investigates atmospheric corrosion of structural steels exposed to the environment by the 2004 tsunami. Some typical structural steels, which have five different shapes, were selected for the test. Atmospheric corrosion tests were employed by referring to ASTM G50 standards. Eight locations were selected as the test sites: Peukan Bada, Ulee Lheu, Lingke, Lampulo, Suak Ribee, Suak Pandan, Suak Seuke, and Suak Geudebang. Following a six-month exposure, experimental results show that the atmospheric corrosion rate for Peukan Bada, Ulee Lheu, Lingke, Lampulo, Suak Ribee, Suak Pandan, Suak Seuke, and Suak Geudebang was 0.043-5.451 mpy, 0.035-3.804 mpy, 0.058-5.332 mpy, 0.045-9.727 mpy, 0.265-3.957 mpy, 0.073-2.970 mpy, 0.090-4.101 mpy, and 0.380-6.379 mpy, respectively. The results show that the relative corrosion resistances for all structural steels exposed in these areas can be categorized as good to outstanding. Hence, it is safe to utilize the selected structural steels regarding their atmospheric corrosion resistance. © Universiti Malaysia Pahang.

Concept of fisher community group (KUB) has been developed concerned with poverty alleviation through empowerment programs. Attempts to resolve KUB problems, particularly, in Barsela Aceh, Indonesia have been performed by numerous parties. However, up to this moment, the increased welfare and KUB empowerment in Barsela Aceh have not showed satisfactory outcomes. Hence, it requires a real concept that can be continuously implemented for KUB’s institutional strengthening development and is locally based. The study aims to figure out institutional development strategies of gillnet fisher KUB in Barsela Aceh. The result of the study showed that there are four system elements to be noted in the implementation, namely: (1) development goals; (2) development challenges; (3) development activities; (4) all actors involved in the development. Key sub-elements as the factors that play critical roles for the successful implementation of development model in each element are increasing human resources quality, work ethic, a relatively high investment fund and operational cost, and the formation of cooperative unit and Ministry of Marine Affair and Fisheries (MMAF). © 2016 BIOFLUX SRL.

Toxicity is a major limitation to successful spermatozoa cryopreservation of fish. Due to this problem, it is critical to find potential cryoprotectants which are more environmental-friendly, non-toxic, easily prepared, and available at affordable prices. Hence, the objective of the present study was to investigate several natural cryoprotectants for optimal cryopreservation of the African catfish, Clarias gariepinus, Burchell 1822 (Pisces: Clariidae) spermatozoa. Three natural cryoprotectants were tested - egg yolk, glucose, and honey, while DMSO was used as a control at different concentrations (5, 10, and 15%). Sperms were diluted with coconut water at a dilution level of 1 : 20 sperm to extender (v/v). Diluted sperms were kept at 4°C for 5 min, then at 0, -4, and -79°C for 5 min respectively, and stored in liquid nitrogen (-196°C) for 45 days. The cryopreserved sperms were thawed in a water bath (37°C) for 5 min and evaluated for fertilization and hatching rates. The data were subjected to analysis of variance (ANOVA), followed by comparison of means using Duncan's Multiple Range Test. The fertilization and hatching rates of African catfish in all cryoprotectants improved with concentration increasing from 5 to 10% but then decreased when concentration was increased to 15%. The ANOVA test showed that the differences in cryoprotectants used significantly affected fertilization and hatching rates of African catfish. Overall, the fertilization and hatching rates were higher in DMSO for all concentrations compared to other cryoprotectants. However, 10% egg yolk resulted in higher fertilization and hatching rates compared to other natural cryoprotectants. It was concluded that 10% egg yolk was the most suitable concentration for African catfish spermatozoa cryopreservation compared to other natural cryoprotectants tested.
