Abstract

Pakan merupakan kompenen utama dengan biaya paling mahal dalam budidaya ikan secara intensif. Oleh sebab itu, dicari alternatif pakan murah dengan teknologi sederhana untuk menekan biaya operasinal pakan. Penelitian ini bertujuan mengetahui waktu efektif yang dibutuhkan untuk fermentasi limbah ampas tahu dan isi perut ikan tongkol krai (Auxis thazard) dan mengetahui koloni bakteri. Penelitian dilaksanakan Juni sampai Juli 2021 di Balai Penerapan Mutu Produk Perikanan (BPMPP) Makassar. Metode penelitian ini bersifat eksperimental yaitu fermentasi limbah ampas tahu dan isi perut ikan tongkol selama 4, 8 dan 12 hari dengan perbandingan 1:1 (isi perut ikan tongkol: ampas tahu). Hasil fermentasi kemudian dilakukan perhitungan koloni bakteri menggunakan ALT. Hasil penelitian ALT menunjukkan jumlah bakteri pada fermentasi ampas tahu dengan isi perut ikan tongkol yakni 3.7x106 koloni/g - 5.4x106 Koloni/g pada ikan kecil, 4.2x105 koloni/g - 22.3x105 koloni/g pada ikan sedang, dan 4.2x105 koloni/g - 22.3x105 koloni/g pada ikan besar. Bahwa waktu fermentasi ampas tahu dengan isi perut ikan tongkol berkontribusi terhadap peningkatan jumlah total bakteri. A B S T R A C T Feed is the main component with the most expensive cost in intensive fish farming. Therefore, it is necessary to look for cheap feed alternatives with simple technology to reduce feed operational costs. This study aims to determine the effective time required for fermentation of tofu waste and entrails of tuna krai (Auxis thazard) and to determine bacterial colonies. The research was carried out from June to July 2021 at the Makassar Fishery Product Quality Application Center.

Abstract

Vibrio harveyi is a Gram-negative marine bacterium from the genus Vibrio known for its ability to emit light (bioluminescence). This bacterium is rod-shaped, moves using flagella at one end, has facultative anaerobic properties, and thrives in environments with high salt content (halophilic). Vibrio harveyi is often found in tropical and subtropical marine waters, especially in coastal ecosystems. Nanotechnology, which is the focus of this study, is a technology based on objects (structures) that are at the nanometer level, often used in biomedical and environmental applications. The purpose of this study was to determine the effect of SLS (nanoenzyme) in inhibiting the growth of Vibrio harveyi, which can cause disease in various marine organisms, including fish and shrimp. The method used in this study was experimental with a quantitative approach, where various concentrations of SLS were tested on bacterial growth. This study was conducted from June to July 2024, under controlled laboratory conditions. The results of this study indicate that the effect of SLS (nano enzyme) cannot inhibit the growth of Vibrio harveyi bacteria at various concentrations, namely 100%, 40%, 20%, and 10%. This is thought to be due to the particle size of the nano, where a smaller nanoparticle size can increase its effectiveness as an antimicrobial. In addition, several other methods need to be tested on SLS (nano enzyme) to understand further its ability to inhibit the growth of Vibrio harveyi bacteria, such as combining with other antimicrobial materials or modifying the nanoparticle structure.

Abstract

This study aims to examine the effect of fermented maggot feeding on the survival and growth of tilapia (Oreochromis niloticus) as an effort to increase feed efficiency in fish farming. Maggots are known as an alternative feed source rich in protein, but the fermentation process is needed to increase the digestibility and availability of nutrients. This study was conducted for six weeks at the Moncongloe Aquaculture Institute using an experimental trial method with a Completely Randomized Design (CRD) consisting of four treatments, namely A (maggots without fermentation as a control), B (maggots fermented with SLS), C (maggots fermented with EM4), and D (maggots fermented with Yakult), with each treatment being repeated three times. The main parameters measured included survival and absolute weight growth of tilapia. Based on the results of the study, the highest survival data was obtained in treatment B with a value of 86.7%, followed by treatments C and D which were each 83.3%, and treatment A (control) of 73.3%. Meanwhile, the absolute weight growth parameter showed the highest value in treatment B at 5.92 g, followed by treatment C at 5.79 g, treatment D at 5.58 g, and treatment A at 5.29 g. The results of the analysis of variance (ANOVA) revealed that the provision of fermented maggot feed did not have a significant effect on the survival of tilapia, but had a significant effect on its absolute weight growth. The treatment of maggot fermented with SLS (treatment B) showed superior results compared to other treatments, indicating that certain types of fermentation can increase the effectiveness of feed in supporting the growth of tilapia. Thus, this study provides scientific evidence that maggot fermentation, especially using SLS, is a potential method to improve the quality of fish feed, so that it can be applied as an innovation in the development of more efficient and sustainable fish farming

Abstract

Kappaphycus alvarezii seaweed produces carrageenan; its growth and development are highly dependent on the quality of the waters and nutrients such as nitrate, phosphate, and potassium. The planting method that cultivators often carry out is to take it directly from the seaweed that is being harvested. This pattern makes the growth of seaweed less than optimal. One solution is to fertilize. One type of fertilizer that can be used is natural fertilizer, such as kasgot fertilizer. This study aims to determine the combination of soaking time and concentration of kasgot fertilizer that effectively increases the growth and carrageenan content of Kappaphycus alvarezii. This research method uses the treatment of the duration of kasgot fertilizer immersion for 2 hours, 4 hours, 6 hours and without immersion (control) and the concentration of kasgot fertilizer of 2 grams, 4 grams, 6 grams, and without kasgot fertilizer (control), repeated 3 times. The results show that the kasgot fertilizer immersion treatment can increase weight, growth rate, and carrageenan value. The higher the dose given, the higher the weight, growth rate, and carrageenan value, although in statistical tests, it was found that the immersion treatment did not significantly affect weight or growth rate. Water quality during the study (temperature, salinity, pH, and depth) was still within the standards for cultivating K. alvarezii seaweed. Further research is needed on using kasgot fertilizer in cultivating other types of seaweed or using different doses.
