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

Kappaphycus alvarezii is used in industry as a food ingredient, a source of hydrocolloids, cosmetics, food additives, animal feed, fertilizers, biofuels, and medicinal ingredients. K.alvarezii is cultivated in several areas in Indonesia, including on the island of Lombok. The production of K.alvarezii is related to its growth and it is related to its phytohormones. K.alvarezii cultivated in Lombok is currently not known for its composition and amount of phytohormones. The content of phytohormones at different planting ages is of course different. The purpose of this study was to determine the number of phytohormones in seaweed K. alvarezii at different planting ages. This study was conducted in Ekas Bay, Lombok, Nusa Tenggara Barat from June to December 2020. The study used experimental methods and descriptive data analysis. The results of this study explain that currently cultivated K. alvarezii contains cytokinins, auxins, and gibberellins. Cytokinins obtained on the 9th day of planting were 11.62 ppm and increased on the 18th day to 12.34 ppm. At the next planting age, it continued to decrease on the 27th day to 11.43 ppm and at harvest time, the 45th day of 10.69 ppm. Auxin detected in the seeds used was 644.93 ppm, on the 27th day of 14.27 ppm, on the 36th day of 1078.25 ppm. Giberilin was detected on the 9th day at 0.49 ppm. This study concluded that K. alvarezii at different planting ages had different phytohormones content.

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.

Abstract

Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami.

Abstract

Laundry detergent waste is toxic and can harm the environment and aquatic life. This study aims to find out the effect of detergent waste on the growth and mortality of gourami (Osphronemus gouramy) seeds and the threshold value of laundry detergent waste that can still be tolerated by gourami seeds. This research was carried out from December 2020 to January 2021 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine Science (FPK) University of Riau. This research method used an experimental method using a completely randomized design (CRD) method with three tests namely the preliminary test, acute toxicity test, and sublethal test. Observation of fish behavior and morphology during the test is described descriptively. In the preliminary test, the lower and upper threshold values were 10 ml L-1 and 100 ml L-1. Then in the acute toxicity test, the value LC50-96 hour was obtained at 30.1 ml L-1 with a biological safe limit value of 0.301 ml L-1. The best treatment obtained from the sublethal test was P1 with a concentration of 0.3 ml L-1 resulting in an absolute weight gain of 1.03 g, a specific growth rate of 1.56%, and a survival rate of 83.33%. The mortality rate is influenced by the concentration of detergent waste, the higher the concentration of detergent waste, the higher the mortality rate. Detergent waste that enters the waters affects the surface tension of the water so that the oxygen diffusion process is hampered, the reduced dissolved oxygen stresses the fish. Detergent waste can also enter the fish's body, irritating the gills and other organs, which can lead to death.
