Abstract

The growth rate of Hermetia illucens larvae in the bioconversion of organic waste is influenced by the media and environmental conditions where the BSF lives. This study aims to determine the effect of the feed formula on the growth of Hermetia illucens larvae in the bioconversion of organic waste. This research method was carried out by rearing BSF larvae, making BSF feed formulas, determining larval length, determining the weight and weight of BSF cassava. The results showed that the feeding formula from fish waste, tapioca waste with a chopped diameter of 10,20,30 mm gave a significant effect on the growth of BSF larvae (larval length, larvae weight) and BSF maggots. The provision of 20 and 30 percent fish waste has a higher weight and length with a chopped diameter of 20 and 30 mm.

Abstract

This research is an experimental study that aims to determine the effect and optimum concentration of shelland head of white shrimp (Litopenaeus vannamei) on reducing hypercholesterolemia in mice (Mus musculus).This study consisted of 4 treatment groups: P0 (hypercholesterol feed mixed with 0% shrimp shell and head flour),P1 (hypercholesterol feed mixed with 5% shrimp shell and head flour), P2 (hypercholesterol feed mixed with 7%shell and shrimp head flour), and P3 (hypercholesterol feed mixed with 9% shell and shrimp head flour). Theresearch method consisted of the manufacture of hypercholesterolemic feed, the manufacture of shell and shrimphead flour, the manufacture of test animal feed, treatment of test animals, and measurement of cholesterol levels.Data were analyzed using One Way ANOVA and Duncan's test. The average value of initial cholesterol levels inthe P3 treatment group was very significantly different from the P0, P1, and P2 treatment groups. The mean valueof final cholesterol levels in the P2 treatment group was significantly different from P0 and significantly differentfrom P1 and P3. The optimum concentration was 7% (P2) which was able to reduce hypercholesterolemia in mice(Mus musculus) by 0.29%.
