Abstract

The aim of this service activity was to socialize and train fishermen's wives in Cot Seurani Village, Muara Batu Sub-District, North Aceh District how to process fish. The target of the training was that fishermen's wives understand and are creative in producing fish products as healthy alternative snacks for children during their growth and development stages. This activity had several stages which were program planning, preparation, training to process fish into fish nuggets and dragon feet products. From the program planning stage, the survey showed that: 1) the fishermen's wives did not have sufficient skills to process fish; 2) during the catching season, fish is usually sold at a low price; and 3) the children of the fishermen did not like to eat fish and preferred chicken and other street foods. The result of this service activity was that the participants have already had the skills and practiced directly how to make fish nuggets and dragon feets. In conclusion, the fishermen's wives can now provide fish products for their children.

Abstract

Microalgae is one of the natural resources that has the potential to make biodiesel because it contains a fairly high amount of oil. The content of fat (lipid) and fatty acid (fatty acid) in microalgae is a source of energy and is used as raw material for biodiesel. In lipids there are elements of saturated fatty acids that play a role in the process of making biodiesel. The addition of growth nutrients into microalgae culture media is considered the most influential aspect on the quantity of biomass produced by microalgae cultivation. This study aims to determine the effect of chicken manure on the growth rate of Nannochloropsis sp. and to get the best treatment the lipid content of Nannochloropsis sp. of dry weight. The method used in this study was to use a non-factorial Complete RandomIzed Design (RAL) with 3 repeat treatments. The treatments in this study were A: 0 mg/L, B: 250 mg/L, C: 300 mg/L, D: 350 mgL. The results showed that the effect of giving chicken manure with different doses had a very real effect on the density of Nannochloropsis sp, and population peaks. Treatment B with a dose of 250 mg/L of showed the best results with an average density value of 4713 x 104 cells/ml and a population peak of 9415 x 104 cells/ml and the highest lipid levels found in treatment B, which is 12.73.  Water quality during the study was conditioned standard. Temperature 26 - 27 oC, pH 7.1 - 7.7, DO 5.2 - 6.3 and salinity 31 - 34 ppt. Based on the results of the study found that lipid results are high, so it is possible to try biodiesel testing.Keywords: Biodesel; Biomass; Lipid; Microalgae; Nannochloropsis  sp

Abstract

LAS (Linear Alkylbenzene Sulfonate) surfactants are the main cleaning agents from the anionic group found in detergents that are widely used in Indonesia. LAS decomposes in surface water for 1-2 days, in sediments it decomposes for 1-3 days, in marine and estuarine systems it decomposes for 5-10 days. LAS is generally degraded by as much as 90% within 3 months, with a time ranging from 5-30 days (World Health Organization, 1996). LAS surfactants can cause damage to the gill epithelium and blockage of branchiola channels in fish. This study aims to determine the toxic effect of LAS surfactant on the survival of white snapper (Lates calcarifer) fry and to determine the toxicity value of LC50 (Lethal Concentration) of LAS surfactant to white snapper (Lates calcarifer) fry on a laboratory scale. This research was carried out on September 21 – October 04, 2021 at the Marine Science Laboratory, Faculty of Agriculture, Malikussaleh University using laboratory experimental methods with 5 treatments, namely: control treatment A (0 ppm), B (0.83 ppm), C (1.58 ppm). ), D (2.16 ppm), and E (2.91 ppm). The results of this study cause barramundi to experience irregular movements, mouth opening and operculum tend to be fast and irregular, scales are pale and peeling, and cause death, LAS surfactants affect water quality such as pH and dissolved oxygen, but have no effect on salinity and temperature. The 24-hour LC50 value is 1.95 ppm, the 48-hour LC50 value is 1.86 ppm, the 72-hour LC50 value is 1.70 ppm, and the 96-hour LC50 value is 1.58 ppm.Key words: LAS surfactant; LC50; toxicity; white snapper
