Abstract

This study aims to analyze the distribution of species on three different transects to evaluate the diversity of aquatic ecosystems and its implications for the economic potential of coastal communities. Sampling methods were carried out on three transects by recording the abundance of 48 species from the mollusk, crustacean, and fish groups. Data analysis included the calculation of the Shannon-Wiener diversity index (H), evenness index (J), and dominance index (C). The results showed that Transect B had the highest total abundance (2,617 individuals) with the highest diversity index (H=2.617) and the best evenness (J=1.094). Dominant species differed on each transect, with Setipinna taty dominating Transect A (500 individuals), Petek (Secutor rocunius) dominant in Transect B (500 individuals) and Transect C (450 individuals). Species distribution showed significant habitat heterogeneity with some species showing specific habitat preferences. From an economic perspective, the presence of high-value commercial species such as kalampa anchovies, green mussels, mangrove crabs, and tiger prawns demonstrates significant potential for the development of capture fisheries, aquaculture, seafood processing, and marine ecotourism. High species diversity opens up opportunities for business diversification that can reduce economic risks and increase incomes in coastal communities. This study recommends sustainable management that integrates conservation with economic development through zoning of water use, establishing sustainable fishing quotas, and developing community capacity in seafood processing.

Abstract

This study aims to determine the cultivation of sangkuriang catfish (Clarias gariepines) for 59 days. The method used in this study is observation by collecting primary data directly from the field. During the study, the highest pool water temperature was found in the second week of 29.11 oC and the lowest temperature of pool water was found in the third week of 28.22 oC. The temperature of the pool water in the morning is lower than in the afternoon. This is influenced by sunlight that directly enters the pond which results in an increase in the metabolic process of the catfish body. The pH of Sangkuriang catfish farming pond ranges from 7.8-7.25. If the highest pH value indicates that the waters are alkaline, on the contrary, if the low pH value indicates acidic, the conclusion is that the salinity treatment of the medium does not have a significant enough effect (P<0.05) on the survival rate of catfish. Sangkuriang catfish is a type of fish that is able to survive and breed in conditions where water is less oxygen and low pH levels, in the first week the oxygen degree is 1.25 and the lowest at 0.65. Catfish tend to be more active in warm water temperatures, but they can also survive in winters with lower temperatures. However, they may become less active and require extra attention to ensure the water temperature remains within limits they can tolerate.

Abstract

This study aims to examine the application of the Outcome-Based Education (OBE) approach in Conservation Biology lectures and its impact on improving students' knowledge, practical skills, and attitudes towards conservation issues in the campus environment. This study uses a quantitative method with an experimental design, where data is collected through pre-test and post-test questionnaires, field observations, interviews, and evaluation of conservation projects carried out by students. The results showed a significant increase in students' knowledge of conservation, with the average post-test score increasing by 30%. Students also demonstrate improved practical skills in designing and implementing conservation projects, such as greening and waste management on campus. In addition, the implementation of OBE has succeeded in fostering a more caring attitude towards environmental conservation, with 75% of students showing a stronger commitment to conservation issues after attending OBE-based lectures. Student involvement in conservation activities on campus has also increased, with 70% of students actively participating in various conservation programs. However, this study also finds challenges related to limited resources and time in the implementation of larger conservation projects. Overall, this study indicates that the OBE approach can be an effective method in improving students' knowledge, skills, and attitudes towards conservation, and can strengthen environmental conservation efforts on campus.

Abstract

Kersen leaves (Muntingia calabura L.) are known as herbal plants used to lower blood glucose levels. This study evaluated the protective effect of ethanol extract of kersen leaves on the histopathology of the liver of white rats (Rattus norvegicus) model of diabetes mellitus. The experimental study with a Complete Randomized Design (RAL) involved five treatment groups and three replicates, using 55 streptozotocin (STZ)-induced mice. The results showed that the administration of 15% (K5) of kersen leaf ethanol extract improved the structure of hepatocytes, resembling normal tissue, compared to the positive control group (K2) who experienced severe necrosis and degeneration. In conclusion, 15% kersen leaf ethanol extract is effective in improving liver damage due to diabetes and potentially lowering blood glucose levels.
