Abstract

The Covid-19 pandemic has had quite a broad impact on the community's economic sector. This condition is also felt by Micro, Small and Medium Enterprises (MSME), including business actors in the fisheries and marine sectors. The study activities were carried out for 3 months from July to September 2021. This research used survey methods and interviews with business actors. The data collected is in the form of primary and secondary data. The data obtained were analyzed by descriptive qualitative. From the results of the study it can be seen that processing business actors are quite feeling the impact of this covid-19. The results of the study in terms of sales turnover experienced a significant decline (between 40 – 60%). The sluggish consumer demand for amplang products is due to various reasons such as restrictions on people's mobility (PPKM) and declining people's purchasing power.

Abstract

Freshwater lobster (Cherax quadricarinatus) is a type of crustacean (crustacean). Freshwater lobster is a type of shrimp that lives in shallow fresh inland waters, with a muddy substrate and lots of gaps and cavities to hide. The cultivation of freshwater lobsters is quite easy because the tolerance to the environment is quite high with relatively few disease problems. Molting is a natural process that occurs in freshwater lobsters as their bodies grow. Calcium is one of the mineral elements that lobsters really need to form new shells. In addition to calcium, lobsters will also undergo a mineralization process to form new membranes using calcium absorbed from the environment in which they live. The purpose of this study was to determine the effect of supplementation of calcium flour from crab shells on commercial feed on molting frequency, absolute weight and length, survival of freshwater lobster, and determine the appropriate dose of calcium flour supplementation of crab shells. This study used a completely randomized design (CRD) with 4 treatments and 4 replications with additional doses of calcium flour, 0%, 2%, 4%, and 6% per kg of feed. The stock density of freshwater lobster was 7 individuals per aquarium for 30 days of rearing. The results showed that the addition of shell calcium powder of as much as 4% (treatment C) was the best dose with 2 molts/ind and the lowest was in treatment A (control). The highest growth in absolute weight and absolute length was at a concentration of 4% (treatment C) 2.34g and 1.55 cm, the lowest value was obtained at treatment A (control) 1.63g and 0.95 cm. Supplementation of crab shell calcium flour in commercial feed for crayfish did not have a significant effect on the survival (SR) of freshwater lobster.

Abstract

Food waste in urban areas is an endless problem, considering that waste will continue to exist. The technique of managing waste to become an alternative feed for catfish is one of the steps to overcome the problem of waste and at the same time becomes an alternative fish feed solution for fish cultivators. The purpose of this research is to process food waste into fish feed. The method used in writing this article is literature review. Based on the results of the literature review and the author's analysis, it can be concluded that food ingredients that can be processed into catfish feed are food waste by utilizing fermentation or by mixing or formulated with other raw materials such as (fish meal, magot, tofu dregs, and fine bran). The fermentation process can use fishery products sold in the market, including (EM4, Boster, etc) which are mixed with molasses.

Abstract

This study aims to determine the secondary metabolic content of saponin contained in the active fraction of sea cucumber (Stichopus vastus) by using metabolic test reagents and thin-layer chromatography (TLC) analysis. The active fraction was given the reagent in the form of HCl 2N and strong acid then continued with analysis to determine the Rf value and lieberman-burchad reaction. The results of the metabolic reaction test showed that the active fraction contained steroidal saponin compounds characterized by the presence of a stable foam and the formation of a greenish-green color. TLC analysis produced a single stain with an Rf value of 0.9 and a bluish color reaction after being given Liberman-burchad which confirmed that the saponins contained in the active fraction of sea cucumbers were steroidal saponin.
