Background: Bacteria are unicellular prokaryotic microorganisms which are abundant in nature. This study aims to isolate and identify bacteria present in the leaves of Kawista (Limonia acidissima L.). Method: The identification process was carried out in a microbiology analyzer with the help of the BD Phonix M50 identification tool. The study was conducted at the West Nusa Tenggara Province Testing and Calibration Laboratory for Health, using kawista (Limonia acidissima L.) leaves obtained from West Sumbawa Regency. Results: The results showed eight bacterial isolates were found including Bacillus sp, Bacillus megaterium, Staphylococcus sp, Staphylococcus epidermidis, Staphylococcus capitis, Streptococcus oralis, Leuconostoc mesenteroides spp. mesenteroides, and Shewanella putrefaciens. Conclusion: Diversity of types of bacteria can be studied through the process of identification. This study aims to isolate and identify bacteria found in kawista leaves. The identification method is carried out in a microbiology analyzer with the help of the BD Phonix M50 identification tool. Bacteria found on the leaves of kawista (Limonia acidissima L.) consist of a group of endophytic bacteria, lactic acid bacteria, metal reducing bacteria, and pathogenic bacteria.

The use of chemical insecticides as mosquito repellent has the potential to cause negative impacts on health and the environment. Therefore, this study aims to develop Citrussera Spray, an organic mosquito repellent made from orange peel and lemongrass. The content of active compounds such as limonene in orange peel and citronellal in lemongrass have properties as natural repellents. The research method includes extraction of active ingredients using steam distillation and maceration methods, spray formulation, and effectiveness tests on mosquitoes. The results showed that Citrussera Spray has high effectiveness in repelling mosquitoes compared to controls without repellent. In addition, safety tests showed that this product is safe to use without causing skin irritation. Thus, Citrussera Spray can be an innovative alternative as an organic mosquito repellent that is environmentally friendly and safe for health.

Coastal biodiversity plays a crucial role in maintaining the stability and productivity of marine ecosystems. Among the key contributors to these systems are marine invertebrates, particularly molluscs and crustaceans, which fulfil important ecological functions such as nutrient cycling, water filtration, and forming part of the marine food web. However, scientific data on the diversity of marine invertebrates in many Indonesian coastal regions remains limited, especially in remote areas like Labuhan Lalar Village, West Sumbawa Regency. This study aims to identify and classify marine invertebrate species found along the coast of Labuhan Lalar. An exploratory research approach was applied through direct field surveys along the shoreline, using a 3-meter transect from the high tide line toward the sea. Invertebrate specimens were collected manually and identified based on external morphological characteristics. A descriptive analysis was conducted with reference to scientific literature to determine species classification. The research identified a total of 15 marine invertebrate species belonging to two major phyla: Mollusca and Arthropoda. These species were further grouped into three classes: Gastropoda (10 species), Bivalvia (4 species), and Malacostraca (1 species). The presence of these diverse taxa indicates that the coastal ecosystem of Labuhan Lalar remains ecologically functional and supports a variety of marine invertebrate life. In conclusion, the coastal area of Labuhan Lalar demonstrates a relatively high level of marine invertebrate biodiversity. These findings may serve as baseline data for future biodiversity monitoring, conservation planning, and the development of sustainable coastal management strategies in the region.

This research was conducted to evaluate the water quality of Nile tilapia (Oreochromis niloticus) hatchery ponds at the Fish Seed Center (Balai Benih Ikan, BBI) located in Tepas Sepakat Village, West Sumbawa Regency. Water quality is a critical factor that directly influences the success of aquaculture, particularly in hatchery operations where the survival and growth rates of fish fry are highly dependent on optimal environmental conditions. The study assessed key water quality parameters including temperature, dissolved oxygen (DO), pH, ammonia concentration, and water transparency. Measurements were carried out quantitatively through direct sampling from three hatchery ponds containing fry of different ages and sizes, with data collected over three consecutive days during morning and afternoon sessions. The results indicated that all measured parameters remained within the acceptable ranges established by the Indonesian National Standard (SNI 7550:2009) for freshwater aquaculture. Water temperature ranged between 25.9°C and 27.9°C, DO levels varied from 3.9 to 5.2 mg/L, pH values ranged from 7.5 to 8.2, ammonia concentration was consistently below 0.1 mg/L, and water clarity ranged from 40 to 46 cm. Although water clarity slightly exceeded the standard threshold, it was still within a tolerable range that could support sufficient light penetration for photosynthesis without posing risks to the aquatic ecosystem. These findings suggest that the water quality at the BBI Tepas Sepakat hatchery ponds is generally suitable for supporting healthy and productive tilapia breeding. However, continuous monitoring and adaptive water quality management, particularly concerning dissolved oxygen and light penetration, are recommended to maintain optimal rearing conditions and ensure long-term sustainability of the hatchery operations. These findings can serve as a useful reference in promoting sustainable aquaculture practices and can be used in aquaculture training programs to improve water quality management.
