Abstract

The purpose of this study was to determine the differences in the duration immersion with lime betel to the quality of fish skin crackers and the differences in the duration immersion with the best unslaked. The research method uses the experimental method with the aim to investigate the presence or absence of relation causes by giving certain treatment to the experimental group. The experimental design uses in this study is a Completely Randomized Design (CRD) with a single factor, namely the immersion of Tuna skin with a different time. Immersion with different time consists of several treatments, namely: (1) Treatment A: Immersion of fish skin with a duration of 6 hours. (2) Treatment B: Immersion of fish skin with a duration of 12 hours. (3) Treatment C: Immersion of fish skin with a duration of 18 hours. (4) Treatment D: Immersion of fish skin with 24-hour duration. The results of the study of differences in the immersion of Tuna fish skin for 6, 12, 18, and 24 hours did not show no significant difference (P>0.05) on water content. The highest water content was obtained in the immersion treatment for 24 hours which is 6.60% which was not significantly different from other treatments. Betel lime solution Ca (OH)2 can react with pectin in the material, thus forming calcium pectate. The content of pectin in the material affects the hardness (texture) of the material. This shows that the difference of soaking time with whiting on the quality of Tuna fish skin crackers shows no significant difference (P>0.05) statistically on the overall taste and acceptance and shows a very significant difference (P<0.01) statistically for taste and aroma. Subjectively, the best soaking for the process of making Tuna fish skin crackers is soaking for 18 hours

Abstract

One of the most important factor in mud crab’s (Scylla serrata) aquaculture is feed. Crab’s feeds must contain nutrients which needed by crabs, such as protein, carb, fat, vitamin, and mineral which can be found in BSF maggot flour. BSF maggot flour could be alternative feed since BSF maggot does not bring or being disease agent and maggot contain high protein, between 40% - 50%. This research investigate about BSF maggot flour percentage influence as substitute feed for mud crab’s weight growth rate and survival rate. This research was conducted from March to May 2021 in the Wanasari Fisherman Group’s Ecotourism Areas, Tuban, Bali. The method used in this research is experimental method with completely randomized design. The obtained data were analyzed by using analysis of variance (ANOVA) and continued by Least Significance Different (LSD) test. The research result showed that the use of BSF maggot flour percentage has influenced on mud crab’s weight growth, but it has no effect on the mud crab’s survival rate.

Abstract

Plankton is instrumental in the aquatic ecosystem, plankton can be an indicator of fertility and pollution. The quality of a water especially the flooded waters can be determined based on the fluctuations of the plankton population that will affect the trophic levels of the waters. The quality of a water can be measured by knowing the value of the Saprobic Index (SI). The Saprobic index is an index that closely relates to the pollution level. This research aims to determine the level of fertility and pollution levels in the waters of Telaga Tunjung Dam, based on the status of Trophic and Saprobic's structure of Phytoplankton, knowing the relationship (linkage) of trophic status and structure Saprobic phytoplankton with variable water quality in Telaga Tunjung Dam. The methods of study used are descriptive methods of case study. The research was conducted on five stations with four repetitions. Plankton sampling performed actively using plankton net with mesh size 60 μm diameter 25 cm. Based on the results of the status of the trophic waters in Telaga Tunjung Dam is at the head of high Water Fertility (Eutrofik). The pollution level is mild to moderate water with a saprobic index from 0,739 to -0,583. The trophic level relationship and the saprobic structure with the water quality variable show that good water quality affects the abundance of high phytoplankton and mild to moderate pollution levels.

Abstract

Snakehead fish (Channa striata) is a freshwater fishery commodity in Indonesia which has a high protein content. Many studies on the benefits of snakehead fish have resulted in an increase in the amount of demand for these fish. One of the production factors that support fish farming is feed. The snakehead fish seeds have an average length of 2 cm, with rudimentary digestive organs. Therefore, the most suitable feed as seed feed is natural food. Commonly used natural feed is water fleas (Daphnia sp.) and silk worms (Tubifex sp.). This study aims to determine the effect of a combination of feed on the growth of snakehead fish seeds and to determine the combination of feed that gives the highest growth in snakehead fish seeds. This research was conducted at the Fisheries Resources Development Laboratory, Warmadewa University for 60 days, from March to April 2020. The method used in this study was an experimental study using a completely randomized design (CRD) with six treatments and three replications. The analysis used in this study was Analysis of Variance (ANOVA), and continued with the Least Significant Difference (LSD) test. The results showed that there was an effect of combination feeding on the growth of snakehead fish as indicated by the increase in absolute weight and length. And the sixth treatment is a combination of feed that provides the highest growth in snakehead fish seeds.
