    Coral reef fish is one of the main components making up the ecosystem of coral reefs. There is a strong mutual dependence between reef-forming corals and fish that inhabit coral reefs. Various fish species use coral as a food source and habitat. This article describes the impact of coral bleaching on the diversity, density, and biomass of coral reef fish in the waters of Sekotong Bay, West Lombok. Underwater visual census (UVC) methods are used to obtain data on species, the number of individuals per species, and fish size at transect length 70 meters and width 5 meters. Simple linear regression analysis that is used to assess the impact of coral bleaching on the condition of coral reef fish shows that coral bleaching affects the diversity and density of reef fish. This analysis also showed that coral bleaching affected herbivorous fish biomass but not carnivorous fish. This study concludes that the degradation of coral fish in the Sekotong Bay of West Lombok occurs due to various factors, especially the declining health conditions of coral reef

    AbstractResearch on seagrass fishes resources condition was conducted in the intertidal zone of Ekas Bay, East Lombok. Sampling of fishes was conducted using the swept area method with beach seine. The result of this research in three station showed that the degree of fishes diversity was low. There was a strong indication that the fishes species in the research area were dominated by certain fish species. In general, the firtility of Ekas Bay coastal water was semilar with the other coastal waters, however the environmental condition mainly the low of persentage of seagrass covering in the research location was the main couse of the low diversity of seagrass fish of the area. High exploitation followed by destruction methods of exploitation can be the main causes of fish degradation habitat, mainly in the seagrass of Ekas Bay, East Lombok. Key words: fish habitat, Lombok, marine,seagrass fishs AbstrakPenelitian kondisi sumberdaya ikan padang lamun telah dilakukan di wilayah intertidal Teluk Ekas, Lombok Timur. Pengambilan sampel ikan menggunakan metode swept area dengan pukat pantai (beach seine) di tiga stasiun pengamatan menunjukkan bahwa tingkat keanekaragaman ikan di lokasi penelitian rendah. Ada indikasi yang sangat kuat bahwa dominansi suatu jenis ikan di setiap stasiun pengamatan. Secara umum, kesuburan perairan Teluk Ekas relatif sama dengan perairan lainnya, namun kondisi lingkungan terutama persentasi penutupan padang lamun yang rendah menjadi penyebab utama rendahnya keanekaragaman ikan padang lamun di lokasi penelitian. Tingkat eksploitasi yang tinggi disertai dengan cara eksploitasi yang tidak mempertimbangkan kesinambungan pemanfaatan sumberdaya menjadi penyebab rusaknya habitat ikan, khususnya padang lamun di Teluk Ekas, Lombok Timur. Kata kunci: ikan padang lamun, habitat ikan, laut, Lombok

    Get PDF
    Shallots have long been cultivated by farmers intensively because shallots have a high economic value, so they become a source of income for farmers. Shallots are annual plants belonging to monocotyledonous plants that have multi-layered tubers formed from layers of leaves that enlarge and unite with cylindrical leaves. The soil fertility level influences shallots' growth, development, and production, requiring additional fertilizers. One of the good fertilizers used is vermicompost. Vermicompost is an organic fertilizer containing microbes and elements required for plant growth. This study aims to determine vermicompost's effect on shallot growth (Allium ascalonicum L.). This study used a completely randomized design with ten replications. The treatment levels consisted of P0 = 0 grams of vermicompost per 1 kg of soil, P1 = 40 grams of vermicompost per 1 kg, P2 = 80 grams of vermicompost per 1 kg of soil, and P3 = 120 grams of vermicompost per 1 kg of soil. Parameters observed were the number of leaves, number of tubers, plant height, wet weight, dry weight, and chlorophyll content of shallot. The research data were analyzed using ANOVA and Duncan's Multiple Range Test at the 5% level. The results showed that the addition of vermicompost had a significant effect on the number of leaves and chlorophyll content of the shallot but had no significant impact on the number of bulbs, plant height, wet weight, and dry weight of the shallot
