Abstract

This study aims to examine the toxicity of phenoxy acid herbicides on vannamei shrimp mortality, by conducting preliminary tests, persistence tests, mortality tests, and water quality. The research design used the regression method and probit analysis with 6 treatments and 3 replications, namely A herbicide concentration of 0 ml/L, B herbicide concentration DMA-6, 0.025 ml/L water, C herbicide concentration DMA-6, 0.005 ml/L water, D DMA-6 herbicide concentration, 0.075 ml/L water, E DMA-6 herbicide concentration, 0.1 ml/L water and F DMA-6 herbicide concentration, 0.125 ml/L water. Pesticides do not affect temperature changes, dissolved oxygen (DO), Salinity, and pH. Clinical symptoms due to Pesticide exposure to vanamei shrimp are irregular movements, shells peeling off, and swimming close to aeration until they die. The LC50 value in the herbicide toxicity test was 0.124 mg/l at 24 hours, 0.099 mg/l at 48 hours, 0.073 mg/l at 72 hours, and 0.026 mg/l at 96 hours.

Abstract

Milkfish is a leading commodity for Indonesian mariculture which is quite promising, so milkfish productivity must be increased. The problematic factor in cultivating milkfish is feed. Lamtoro leaves (Leucaena leucocephala) are a potential biological resource and have high protein content as a raw material for making feed. However, lamtoro has a high fiber content which can be reduced by fermenting using bio intan tani and attractants to cover the aroma of lamtoro which fish do not like. This research aims to test the effect of adding fermented lamtoro leaves to artificial feed on the growth of milkfish. The research was carried out on March 22 - April 22 2022 at Kembang Tani Farm Lancang Barat, North Aceh, Aceh. The research used a non-factorial Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications, Treatments A, B, C and D with concentrations of 0%, 15%, 20% and 25% respectively. Based on the F test analysis (ANOVA), the results gave a significant effect on feed response, weight gain, length increase, aroma with a Sig value < 0.05 and gave results that had no real effect on survival rate and feed conversion value with a Sig value > 0. 05.

Abstract

Nannochloropsis sp. is the green colored microalgae with its round shape of cell. This microalgae has lipids of 28,7% by dry weight, especially unsaturated fatty acids which can be transesterified to produce methyl ester and be a potential as biodiesel feedstock. The content of biodiesel Nannochloropsis sp. reaches 80% of dry weight and has the sama characteristics as vegetable oil. In the lipid extraction process many problems were found, one of which was the cell wall of Nannochloropsis sp. which prevents the lipid from being extracted. This research was carried out on 10 December 2022-28 February 2023 at the Hatchery and Aquaculture Technology Laboratory aquaculture study program, faculty of agrigulture, Malikussaleh University, Chemical Technology Laboratory at Lhokseumawe State Polytechnic and at The Environmental Quality Testing Engineering Laboratory At Syiah Kuala University, Banda Aceh. This study used a laboratory experimental method using a Non-Factorial Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. Treatment A Control, treatment B Heating, treatment C Osmotic shock and treatment D Homogenizer. Based on statistical analysis of the F test (ANOVA) showed that the percentage of lipid from the application of pretreatment gave significantly different resulst to the percentage of lipid from the application of pretreatment. The highest lipid was found in treatment B which was 21,14% and the lowest lipid was in treatment C which was 12,51%. The highest lipid producer from the application of pretreatment is using the heating method. Biodiesel is obtained through a tranesterification process using methanol as a solvent and KOH catalyst.
