Published: November 2024

One of the many advantages of chitosan obtained from the shells of mud crabs is that it acts as an antibiotic against acne. This study set out to determine chitosan’s characteristic properties that were taken from Scylla sp shells, the nanoparticle’s dimension, and the optimal chitosan nanoparticle concentration to stop the growth of acne-causing Staphylococcus aureus and Staphylococcus epidermidis. A descriptive approach is used in this research methodology to evaluate the chitosan’s quality and antibacterial efficacy. Chitosan nanoparticles at varying concentrations (0.20%, 0.25%, 0.50%, 1%, and 1.25%) are included as the only independent factor, and changes are examined within a 95% confidence interval. The positive control is ampicillin, while the negative control is acetic acid. A Particle Size Analyzer (PSA) was used to analyze the chitosan nanoparticles’ dimensions, and the results showed that they were 47.04 nm. At different doses, chitosan nanoparticles’ inhibitory effect on the growth of S. aureus and S. epidermidis was assessed. Both S. aureus and S. epidermidis growth were effectively inhibited at a concentration of 0.50 percent. The chitosan nanoparticle activity in this investigation fell within the moderate to strong range.

Published: November 2024

The coastal waters of Dumai, which are directly facing Rupat Island and the Strait of Malacca, are influenced by various coastal activities that are likely to provide inputs for pollutants such as heavy metals that can eventually accumulate in biota, including fish. This condition not only threatens the balance of the ecosystem and the life of aquatic biota, but can also affect the health of people who consume fish from these waters. This study aims to analyze the concentration of heavy metals in threadfin fish (Eleutheronema tetradactylum) collected from Dumai coastal waters and to determine the safe limit of weekly consumption by the community without harmful effects to health. Threadfin fish were taken with a variation in size between 19 to 34 cm, then they were analyzed for heavy metal concentrations (Pb and Cu) in the flesh by referring to the SNI 6989-84:2019 procedure. The results showed that fish with larger sizes accumulated more Pb and Cu metals (2.220 and 0.028 μg/g) compared to medium-sized fish (1.207 and 0.026 μg/g) and small-sized fish (0.811 and 0.015 μg/g). The metal concentration differed significantly (p<0.05) between the three sizes. The longer the size of the fish, the concentration of Pb and Cu will increase. Likewise with the fish weight, the heavier the fish, the concentration of Pb and Cu will also increase. The PTWI value that has been determined by WHO will be achieved if adults with a body weight of 60 kg consume Threadfin fish as much as 1,061 kg/week and 9,130.43 kg/week, while children with a body weight of 15 kg consume the fish as much as 0.265 kg/week and 2,282.6 kg/week, for Pb and Cu.

Mozambique Tilapia Oreochromis mossambicus and Nile Tilapia Oreochromis niloticusare two non-native species of cichlids (Cichlidae: Cichliformes) that have established populations in Indonesia. There are many information about the presence of both non-native species in the country, but detailed distribution is filling a gap of information. We compile unpublished and published distribution records of Oreochromis mossambicus and Oreochromis niloticus from various sources, particularly from iNaturalist (citizen science platform) and GBIF (The Global Biodiversity Information Facility, an international network of country and organizational participants that exists to enable free and open access to biodiversity data from all sources and to support biodiversity science, environmental research and evidence based decision-making). The historical records of O. mossambicus and O. niloticus were reviewed and summarized, and put the certain known distribution records into the map. Our study suggest that O. mossambicus and O. niloticus found widely throughout Indonesia, from Sabang (northwesternost: Aceh Province, Sumatra) and Merauke (southeasternmost: South Papua Province, Papua).

Published: November 2024

This study aims to determine the optimal values of chlorophylla (Chlo) and Sea Surface Temperature (SST) for skipjack fishing (Katsuwonus pelamis) in the Banda Sea and its surroundings using the GAM model and ECDF function. The GAM model yields the formula CPUE = 33.07 + s(Chlo, edf = 7.14, Ref.df = 8.09) + s(SST, edf = 8.95, Ref.df = 8.99), with a significant value for Chlo of 0.58 mg/m3 and an SST of 28.26°C, as well as the highest CPUE value of 51.84. Due to the low performance of the GAM model, ECDF is used to determine the optimal values of Chlo and SST. The results of the Kolmogorov-Smirnov test on the ECDF value showed a p-value for Chlo of 0.0016 and SST of 4.45e-14 (p < 0.05). Thus, there was a significant difference between the f(t) and g(t) distributions at Chlo = 0.28 mg/m3 and SST = 30.57°C. K-Means analysis shows that the optimal value range for Chlo is 0.075 - 0.33 mg/m3 and for SST is 29.47 - 30.47°C. The optimal months are January to June as well as October, where the combination of SST and Chlo concentrations reaches levels that support the productivity of skipjack fishery. However, from July to September, lower SSTs begin to dominate, which can reduce fishery optimality, although some regions still have supportive Chlorophyll. In November and December, SSTs reach very high levels, potentially reducing productivity efficiency.

Dumai City is one of the cities in Riau Province, Indonesia, located in the coastal area. As an industrial and trade city, the fisheries sector in Dumai City is under intense pressure due to this marine activity. On the other hand, Dumai City has the second highest Human Development Index (HDI) value in Riau Province after Pekanbaru City. The high HDI status of Dumai City makes it attractive to study whether it is directly proportional to the HDI value of the fishermen community and its socioeconomic sustainability status. The survey method was used in this study. This study aims to analyze the sustainability status of Dumai City’s fisheries from social and economic aspects by considering HDI indicators in health, education, and economic aspects. This study uses two analysis methods: the calculation of HDI and sustainability status using Rapfish. The HDI value of the Dumai City fishermen community is 69,35. These results show that the condition of the Dumai fishermen community is still relatively low when measured by the HDI indicator. If examined based on sustainability analysis, the social and economic aspects of the Dumai City fishermen community are 39,56, with a less sustainable status.

This study explores the local perspectives on fishing practices and conservation efforts related toPuntioplites bulu, locally known as “Tabingalan Fish” in the Kotopanjang Hydroelectric Reservoir. This species faces growing threats from overfishing and habitat degradation due to the reservoir’s fluctuating water levels and human activities. Using a mixedmethods approach, this research integrates surveys and semi-structured interviews with local fishermen to assess their practices, knowledge, and attitudes towards the conservation of the Tabingalan fish. The findings indicate that while the local population heavily depends on this species for their livelihoods, there is a significant gap in awareness regarding sustainable fishing practices and the importance of conservation. Traditional knowledge remains a cornerstone in the community’s fishing practices, but it often conflicts with modern conservation strategies. The study emphasizes the need for integrating local knowledge with scientific conservation efforts to enhance the effectiveness of existing programs. Challenges identified include limited access to conservation resources and the necessity for more comprehensive community engagement and educational initiatives. This research provides valuable insights for policymakers and conservationists aiming to develop more effective, community-based conservation strategies that can ensure the sustainability of Tabingalan fish while supporting local livelihoods. The study advocates for a collaborative and culturally sensitive approach to natural resource management, promoting a synergy between local communities and conservation authorities.

Hybrid halide perovskites have demonstrated significant efficiency in detecting a broad spectrum of high-energy radiation, including X-rays, gamma rays (γ-rays), and neutrons. Given the common occurrence of mixed radiation fields, we investigated the performance of a perovskite-based detector in a neutron-gamma mixed field. A large methylammonium lead tribromide (MAPbBr3) single crystal (SC) was synthesized via the oriented crystal-crystal intergrowth method. This SC was used to fabricate a gamma detector with carbon electrodes, which was tested in the CROCUS zero-power reactor cavity. The detector’s photocurrent response exhibited a strong correlation with known gamma dose rates, as measured by an ambient Berthold LB 112 gamma probe, facilitating the accurate conversion of photocurrent to dose rate. Notably, the device did not exhibit degradation under neutron radiation exposure. To further assess the impact of neutrons, X-ray diffraction and electron paramagnetic resonance analyses were performed on small MAPbBr3 SCs grown by inverse temperature crystallization. These SCs were irradiated within the CROCUS reactor core and by a Pu-Be neutron source at liquid nitrogen temperature. Our findings indicate that the perovskite material can withstand the nominal in-core operation conditions of the CROCUS reactor. Additionally, it endures irradiation at liquid nitrogen temperature, corresponding to a fast neutron fluence of approximately 1010 cm-2 and a gamma radiation dose of about 50 Gy, confirming only the temporary creation of defects. No signs of long-term deterioration were observed, suggesting a potential self-healing mechanism. This resilience positions perovskite SCs as viable candidates for in-core radiation detection, supporting the further development of miniaturized MAPbBr3 SC devices for such applications.
