Abstract

Gill net fishing gear is a passive fishing gear that usually blocks the swimming direction of fish, with the addition of bait as a lure is expected to increase the chances of fish that will be used as a target catch willing to enter the fishing gear. aims to analyze the composition of crab catches on different baits and analyze the size distribution of crabs. The expected benefits of this research are as one of the information materials for efficient crab fishermen about the use of chicken intestine waste bait and fly fish against crab catches with bottom gill net fishing gear related to the availability of fish bait stocks that are uncertain and quite expensive prices. This research was conducted in January - February 2022. From the results of the t-test analysis, the tcount value was obtained at 5.014 while the t-table was obtained at 2.042 with a significance value of 0.000. Because the t-count value is greater than the t-table and the significance value is smaller than the real level of 5% or 0.05, it is concluded that there is a difference in catches between the chicken intestine bait group and fly fish bait with an average catch using chicken intestine bait higher than using fly fish bait

Abstract

Portunus pelagicus is one type of crab that has a very high economic value. The high selling price of crab encourages an increase in fishing effort, where the pressure of increasing fishing effort can cause less catch per effort obtained. To maintain the sustainability of the availability of fisheries resources, improve community welfare, equality of cultivation technology, investment development, increase foreign exchange, and development of cultivation and crab (Portunus spp.), the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020 was issued to re-regulate the provisions for catching and/or releasing crab, therefore this study aims to determine the feasibility of catching crab (Portunus pelagicus) based on the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020. This study uses a quantitative method by measuring the frequency distribution of carapace width and crab weight which will then determine the frequency of each class by entering the width data of each crab based on the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020. The results showed that more than 90% of the crab catches followed the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020, namely carapace width size above 10 (ten) cm and weight above 60 (sixty) grams per tail. Although the catch of unfit crabs is less than 10%, it should be released back to nature to support the sustainability of crab.

Abstract

Making sweet potato noodle products with Gracilaria sp. seaweed fortification is one of the efforts to provide gluten-free products that are good for health and help the community optimize the selling value of seaweed. This study aims to determine the effect of Gracilaria sp. seaweed fortification on the nutritional value of protein content, water content, and gluten content of sweet potato flour and to determine consumer acceptance of sensory quality in sweet potato noodles (Ipomoea batatas L) fortified with Gracilaria sp. seaweed. This study was conducted in May-July 2024 at the Pangkep State Agricultural Polytechnic Biochemistry Laboratory. This study used an experimental method with a Completely Randomized Design (CRD). The parameters tested in this study were protein content, water content, gluten content of sweet potato flour, and sensory quality, namely: appearance, aroma, texture, and taste. Data analysis of protein content, water content, and sensory quality were analyzed using ANOVA. The results of the study showed that the highest protein content of 3.86% was found in seaweed-fortified sweet potato noodles with a concentration of 10% and the lowest protein content of 3.04% was found in seaweed-fortified sweet potato noodles with a concentration of 0% and the highest water content of 13.19% was found in seaweed fortified sweet potato noodles with a concentration of 10%. The lowest value was 11.55% The conclusion is that Gracilaria sp. seaweed fortification has a significant effect on the Nutritional Value of sweet potato noodles. The sensory quality values ​​for color, aroma, and taste with a concentration of 5% are preferred by consumers.
