Analysis Of The Application Of GMP (Good Manufactoring Practice) In household Scale Pindang Fish Processing : Case Study In Sukabumi City

2025-04-25T07:26:32+00:00

This study aims to analyze the application of Good Manufacturing Practice (GMP) in the cob fish pindang processing industry owned by Mr. Wawan in Sukabumi City. The method used is descriptive research through surveys, direct observation at the production site, and interviews with owners to evaluate aspects of sanitation, packaging, and production supervision. The results of the study show that the implementation of GMP in several aspects such as the selection of raw materials and environmental sanitation, has been well implemented. Weaknesses are still found in quality control, sanitation facilities, and product packaging and labeling systems. Packaging that still uses waste paper is at risk of causing contamination. The lack of separation between the areas of raw material receipt, production and storage increases the risk of cross-contamination. Improving GMP standards can be done by improving sanitation systems, using safer packaging, and implementing simple quality controls such as checklists and periodic evaluations. This improvement is expected to improve the quality and safety of pindang products to comply with applicable food standards.

2025-04-25T01:44:34+00:00

Sidenreng Rappang Regency has great potential in the freshwater fisheries sector, especially in tilapia cultivation and is the main choice for local farmers because the Sidrap area is mostly land and has no coastline. The problem in this study is to determine the most effective type of feed in increasing the growth rate of tilapia. Therefore, the purpose of this study is to identify the best feed to maximize the growth of tilapia. This research was conducted in August-September 2024 at the Fisheries Science Development Pond, Muhammadiyah University of Sidenreng Rappang, Pancarijang District, Sidenreng Rappang Regency, South Sulawesi. The method used in this study is an experimental method with a Completely Randomized Design (CRD) experimental design. The experiment consisted of two treatments with two replications each, so that there were a total of six experimental units. The results of the analysis of variance showed that the provision of natural and artificial feed had a significant effect on the growth rate of tilapia (p <0.05). Further analysis using the W-Tukey test revealed differences between feed A and feed B. Based on the results of the study, it was found that fish fed commercial feed experienced the highest growth with an average of 7.53 ± 0.05, while the lowest growth was found in fish fed natural feed with an average of 5.36 ± 0.11. This shows that artificial feed is more effective in increasing the growth of tilapia because it has a more balanced nutritional content, especially in terms of protein and energy, which is in accordance with the metabolic needs of fish. However, natural feed can still be used to support the survival of tilapia.

Astaxanthin Function as Colour Source in Ornamental Fish

2025-04-25T01:45:39+00:00

Ornamental fish are one of the fishery commodities that continue to grow in Indonesia, with production increasing every year. Color is the most important factor that determine ornamental fish value in market. There are several factors that affect color of ornamental fish, genetics, fish health and the feed given. Astaxanthin, a type of carotenoid, plays an important role in the coloring of ornamental fish. It is known that astaxanthin can produce red colour on fish skin. Astaxanthin cannot be synthesized from within the fish’s body, so it requires external sources through feed. This article was written using a journal review method from several journal and was explained descriptively. The results of the article review obtained were that there are two sources of astaxanthin that are widely used today, namely chemical synthesis and extraction from natural materials. Synthetic astaxanthin has a more economical price but its bioactivity is lower than natural astaxanthin. Natural sources of astaxanthin can be obtained from the microalgae Haematococcus pluvialis, crabs and shrimp. H. pluvialis is a natural source of astaxanthin with the highest content, which can be produced through cultures that are given stress such as changes in temperature and lighting. In addition, shrimp and crabs also accumulate astaxanthin in the body through the consumption of feed rich in carotenoids. Several studies have shown that giving astaxanthin in feed can significantly increase the brightness of the color in ornamental fish.
