Abstract

The market waste is solid waste organic consist of set of many vegetable which are not feasible for sale. The market waste in general predominated by mustard greens, cabbage, tomato, and chayote. One of the market waste treatment using the bioconversion process of the Hermetia illucens larvae (Black Soldier Fly) or commonly called Maggot. The research was conducted to investigate the effect of the type of waste on larvae weights in the bioconversion of market waste using Hermetia illucens larvae (Black Soldier Fly). The research was carried out in september 2020. The research method use was true-experiment. The sample use was 200 Hermetia illucens larvae/treatments taken from the population by technique simple random sampling. The experiment was conducted for 12 days. Samples were taken periodically to be analyzed for their weight, supported by substrate consumption, waste reduction index, survival rates. Based on the results of the study can be concluced that there is giving the mixed mustard greens and cabbage waste produces the largest larvae weight with feed rate 60 mg/larvae/day or average weight of 92,20 grams. At this condition, the optimal waste reduction in the bioconversion process was observed as substrate consumption of 96,80% and waste reduction index of 33,61% obtained in the waste feed media of the mixed mustard greens and cabbage.While the survival rate of 99,90% obtained in the waste media of the mixed mustard greens and chayote with feed rate 60 mg/larvae/day.

Abstract

Kamal District has a mangrove ecosystem area which is a habitat for marine life, including crabs. This study aims to determine the association of Crabs with Mangroves in Kamal District, Bangkalan Regency, Madura. This research uses quantitative methods with the type of survey research and the technique used is purposive sampling. The sampling method uses ladder transect. Based on the results, mangrove data were obtained which were classified into 4 families, 4 genera and 7 species. While crabs consist of 2 families, 4 genera and 4 species. The average value of the mangrove ecological index consists of a diversity index of 1.28 in a medium category, a uniformity index of 0.66 in a high category and a dominance index of 0.32 in a medium category. The average value of the Crab ecological index consists of a diversity index of 1.24 in a medium category, a uniformity index of 0.89 in a high category and a dominance index of 0.32 in a medium category. The result of the ꭓ2 test are that there are 4 positive associations, 2 negative associations and 22 no associations.
