Abstract

The goal of this study was to evaluate the use of BSF larvae meal and oil as feed components in order to determine their impact on Litopenaeus vannamei shrimp growth performance, nutritional composition, and health response. Three shrimp ponds, each with a diameter of 20 m, were stocked with 72.000 Litopenaeus vannamei post larvae (PL-8), resulting in a stocking density of 229 shrimp per square meter. The trial diets comprised three types: control diet (K), diet containing BSF larvae meal (A), and diet containing BSF larvae meal plus oil (B). The parameters observed in this study included shrimp growth and productivity, feed consumption, feed conversion ratio (FCR), survival rate, nutritional composition (proximate, amino acid profile and fatty acid profile), total bacteria in the shrimp's digestive tract, and total hemocyte count in the shrimp's hemolymph. It was found that subtituting fish meal with 34% BSF larvae meal did not affect the growth performance of shrimp raised in shrimp ponds, compared to the control treatment. The assessment of the amino acid profile has revealed minimal variation between treatment. Nevertheless, both treatments A and B exhibited a decreased concentration of unsaturated fatty acids, specifically omega-3 and omega-6, in comparison to control. Meanwhile, treatment B had the highest levels of saturated fatty acid and omega-9 fatty acid content.

Abstract

Ministry of maritime affairs and fisheries (MMAF) has issued guidance on ecosystem approach aquaculture (EAA) as a tool for profitable and sustainable management of aquaculture areas. The Minapolitan area of Klaten district with the superior commodity Tilapia fish has not yet fully implemented EAA. The purpose of this study are: (1) evaluating the management of tilapia fish commodity cultivation areas in Klaten district based on EAA indicators and (2) providing recommendations for interventions to improve the management of tilapia cultivation fishery areas in Klaten district based on EAA indicators. The methods of data analysis used in this study is quantitative analysis using descriptive approach. Data collection uses triangulation techniques where respondents are determined intentionally (purposefully). The study site was in Minapolitan Area 1 (Karanganom, Tulung and Polanharjo) and Minapolitan Area 2 (Ngawen, Kebonarum, and South Klaten) of Klaten regency. The result showed that the management of aquaculture areas with Tilapia as a commodity in Klaten district based on the EAA parameter is in adequate condition with a value of 2.26 for Minapolitan Area 1 and 2.13 for Minapolitan Area 2. Recommendations for interventions are improvements to institutional parameters, monitoring, and evaluation, as well as the role of environmental management in the area.

Abstract

The problem is that waste produced from green mussel shells can result in environmental pollution. Green mussel shells can be used as raw material for making toothpaste. Toothpaste is a care product that has the function of caring for healthy teeth to prevent cavities that use a combination of green mussel shells and lime peel as the main ingredients. This study aims to determine the effectiveness of toothpaste derived from green mussel shells and lime peel. This research was carried out in four stages, namely making green mussel shell flour, making lime peel extract, making toothpaste formulations and testing which included organoleptic, carbohydrate, pH, antibacterial, calcium, viscosity, centrifugation and stability testing. The design used was a Completely Randomized Design (CRD) with 5 treatment levels with different concentrations of green mussel shells, namely P1 (0), P2 (16.5%), P3 (25%), P4 (33.5%), P5 ( 50%).The research results showed that the best treatment was toothpaste with a combination of clam shell powder and lime peel extract in the P5 treatment in the antibacterial test with an inhibitory power obtained of 156.67 ± 15.28. Treatment P5 with a concentration of 50% addition of green mussel shell flour was the best treatment for toothpaste preparations.
