Abstract

White spot syndrime virus (WSSV) is a highly contagious disease in shrimp culture and causing 100% death within 3-10 days of clinical symptoms. WSSV can infect shrimp in post larvae stage (PL) to a size of 40 g. This study was aimed to determine the effect of different salinity against WSSV infection level in post larvae vannamei shrimp (Litopenaeus vannamei). In this study PL 40 size of vannamei shrimp infected with WSSV in virus concentration 20 μg.mL-1 in three different salinity is 5 ppt, 15 ppt, 25 ppt for 4 hours using the soaking method then maintened for 7 days post-infection and then infection level and water quality observed. Data analysis used simple linear regression and F test with a confidence level 95% (P <0.05). The results indicate changes in behavior between healthy and infected shrimp in three levels (mild, moderate, severe). The highest total mild infection in salinity treatment of 25 ppt by 30%, the highest total medium infection at salinity treatment 25 ppt by 37%, the highest total severe infection at salinity treatment 5 ppt by 57%. Shrimp that have mild level of infection are increasing in concominant higher salinity, while the severe infection level has decreases with increasing salinity.

Abstract

Livestock farmers in Kasembon Subdistrict face dual challenges: severe environmental pollution from dumping manure directly into rivers, and economic strain due to high dependence on costly LPG and synthetic fertilizers. This community service program introduces household-scale biodigesters to solve both environmental and economic issues simultaneously. Involving 20 local participants through the Participatory Rural Appraisal (PRA) method, capacity building, and technical assistance, the intervention yielded highly significant outcomes. LPG consumption plummeted from 3.8 to 0.4 cylinders monthly. Behavior completely transformed: previously, 80% of farmers polluted water bodies, whereas today 100% utilize their waste as biodigester feedstock, effectively halting river pollution. Economically, this circular system generates average monthly savings of Rp 206,000 per household by substituting LPG and chemical fertilizers. Participants' technical skills also surged from 1.95 to 4.61. Ultimately, biodigester technology successfully mitigates environmental damage while empowering rural communities toward sustainable energy independence and food security

Abstract

This community service project aims to empower the youth of Karang Taruna in Tamansari Village, Banyuwangi, through social innovation in tilapia cage farming. The program seeks to enhance youth knowledge and skills in aquaculture, fostering greater productivity and community welfare. Through training and mentorship, the initiative aspires to develop an independent and competitive youth group capable of leveraging the village's potential in the fisheries sector. The project results show a positive impact, including increased capacity in institutional and aquaculture skills, the formation of the Pokdakan group, and the construction of nine tilapia cages in residential water channels.
