Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

Around 20% of mangrove forests in Indonesia are in a degraded condition, which has a negative impact on the potential for blue carbon storage. When mangroves are damaged or degraded, carbon stored in the soil and vegetation can be released back into the atmosphere as CO2, ultimately increasing greenhouse gas emissions and exacerbating climate change. Mangrove forests can store up to four times more carbon per hectare, around 8001,200 tons per hectare, than terrestrial tropical forests. This research was conducted in the Wini mangrove forest area, North Central Timor, East Nusa Tenggara (NTT) which directly borders Timor Leste. The determination of the location of the observation station was based on a map of changes in mangrove forest land use obtained from the Geospatial Information Agency. The parameters measured included organic carbon, mangrove area and sediment type. Organic carbon was analyzed using the Loss on Ignition (LOI) method, and sediment grain size was measured using a particle size analyzer. The results of the study showed that the average organic carbon stock in mangrove forests reached 570,600843,600 tons per hectare, with an average change in the area of mangrove forests from 2013 to 2023 of 181.29 hectares and the type of sediment dominated by sandy mud. This change in area is caused by the conversion of mangrove land into ponds, rice fields, and settlements.Keywords:MangroveCarbonSedimentborder Area

Abstract

The role of the river as a site for riverine activities has a huge impact on the economic sustainability of the community and the riverine ecosystem. The Silugonggo River is the only river in Pati Regency that is a very densely populated shipping route. This research was conducted along the Silugonggo River from the Juwana Bridge to the estuary. The purpose of this study was to determine ship activity in the Silugonggo River, determine the feasibility of facilities at Juwana Port and analyze environmental conditions along the Silugonggo River. The method used is a qualitative method with observation techniques and laboratory analysis, which is carried out by observing and recording conditions in the field systematically using primary data in the form of water conditions and secondary data in the form of ship activity and construction data. The results showed that the activities in the port of Juwana include mooring, loading and unloading of goods, ship repair and refuelling of ships. The level of water pollution in the Silugonggo River at 5 sampling points shows that the oil content in the water for points 1, 3, 4 and 5 is still considered safe because it is below the quality standard, but the oil content at point 2 has a very high value from the set quality standard which is 20 mg/L. The pollution that occurs is caused by shipping activities that dump waste into the water and fuel filling activities.Keywords:marine polutionportriverwater qualityoil spill

Abstract

This study investigates the potential of using domestic wastewater as a growth medium for Chlorella sp. and examines how it affects water quality over a period of 24 days. The experiment was conducted using a Completely Randomized Design (CRD) with a single factor: four levels of domestic wastewater concentration0%, 25%, 50%, and 75%each tested in three replicates.The results showed that the highest biomass production occurred on day 8, reaching 0.337 mg/L in the 75% wastewater treatment (TR3), while the lowest was observed in the control group (C) at 0.210 mg/L. Statistical analysis using ANOVA followed by the Tukey test confirmed that the differences between treatments were significant (p 0.05). Correlation analysis showed a strong positive correlation between biomass and dissolved oxygen (DO, 0.949) and temperature (0.626), indicating that optimal light intensity and nutrient availability promote photosynthesis and biomass growth. In contrast, phosphate was negatively correlated with temperature (-0.738), suggesting that higher temperatures accelerate phosphate uptake by Chlorella sp. The study concludes that cultivating Chlorella sp. using domestic wastewater presents a sustainable solution for both biomass production and wastewater treatment. The microalgae help remove excess nutrients like nitrogen and phosphorus, enhancing water quality. However, as the algae decompose, they can also contribute to higher biological oxygen demand (BOD). This dual role underscores the promising potential of microalgae in promoting ecological wastewater management while supporting sustainable biomass production.Keywords:BiomassChlorella sp.Photobioreactorwastewater

Abstract

Indonesia is one of the worlds leading tuna-producing countries. Under the Quota Based Fishing (Penangkapan Ikan Terukur/PIT), its Exclusive Economic Zone (ZEEI) in the Indian Ocean is designated as zone 04 of PIT. This research aims to analyzing the characteristics of tuna fisheries in the zone 04 (Indonesian Fisheries Management Area/IFMA 572 and 573), including tuna production by fishing gear and by port landing, species composition by gear, Landing per Unit Efforts (LPUE) by gear and by tuna species. The most dominant fishing gear for tuna is lines (hand lines, troll lines, kite lines, and rod handlines). Purse seines and longlines also caught a lot of tuna, but their percentages were still lower. The dominant tuna species caught was yellowfin tuna, which came from all types of fishing gear. The average LPUE in 2024 for gillnets was 28.6 kg/days, lines 56 kg/days, purse seine 161 kg/days, longline 58.5 kg/days, and pole and line 268 kg/trip/day. The abundance of ALB was highest in July, but the trend has been increasing since March and began to decline in last year. Pole and line and purse seine were the most productive fishing gear for catching tuna. The abundance of YFT varied greatly with high abundance in March, July, and October. The abundance of BET was high in February, July, and September. SBT is highly abundant in March, April, and July, with some months being empty. Benoa Public Port is recorded as the port with the highest production within Zone 04.Keywords:Tuna fisheriesIndian OceanTuna ProductionComposition speciesLPUEFishing Quotas

Abstract

Koi fish coloration is genetically significant, but environmental factors and color quality can lead to degradation. Some individuals use synthetic dyes to enhance their appearance, which harms the environment. This study explored the effects of microencapsulated Rose sp. flower anthocyanin (MRFA) as a natural alternative dye to enhance the color of Sanke and Kohaku koi fish. Sanke exhibits orange-black hues, while Kohaku shows orange-white hues, allowing for comparative analysis. Before the experiment, MRFA was analyzed using FESEM and XRD to assess the particle size distribution and shape of the anthocyanin microcapsules. A Randomized Complete Design (CRD) with four treatments (T0, 150 mg (T1), 300 mg (T2), and 450 mg (T3)) and five replications were used. Data was analyzed with SPSS. Results showed that MRFA particles were distributed, though not entirely homogeneous (14 m to 170 m), with XRD spectra indicating interactions between maltodextrin and Rose sp. anthocyanin. Results showed that MRFA significantly improved certain color parameters in Sanke, particularly at moderate doses (T1 and T2), but the control group (T0) outperformed MRFA in some cases. In Kohaku, no significant improvement was observed compared to the control, suggesting that MRFA was less effective in enhancing whiteorange pigmentation. Overall, our findings indicate that MRFA supported koi growth but showed limited, strain-specific effects on coloration. Further studies with longer trials and larger populations are needed to confirm its potential as a natural feed additive.Keywords:Herbal extractCyprinus carpioKohakuPigmentSanke

Abstract

Deli River has been designated as a national river that has made a major contribution to the economic growth and development in the Medan city of North Sumatra. However, rapid urbanization and human population growth have caused degradation of the quality of Deli River due to increasing pollution. This study aims to analyze the level of pollution of the Deli River using the Pollution Index (PI) and CCME Water Quality Index (WQI) methods with reference to Government Regulation Number 22 of 2021. The research location was divided into 4 stations from upstream to downstream of the Deli River. Based on PI method, stations 1, 2, and 3 were classified as lightly polluted, while station 4 experienced moderate pollution. The results were different when using the CCME WQI method, which showed that stations 1, 2, and 3 were classified as having fairly good waters, while station 4 was poor waters. Water quality analysis was carried out on 13 parameters, 5 of which exceeded the river water quality standard threshold, namely BOD, ammonia, Pb, Zn, and Cd.Keywords:Deli riverRiver pollutionWater qualityPollution Index (IP)CCME WQI
