This study aims to evaluate the effect of supplementation of natural ingredients in pelleted feed on gonad maturity and survival of female Betta fish (Betta splendens). The research was carried out from April to June 2025 at the Aquaculture Laboratory, Faculty of Agriculture, Muhammadiyah University, Palembang. The research design used a Completely Randomized Design (CRD) with five treatments and three replications (a total of 15 containers). The basic feed used was PF 500 pellets. Treatment consisted of: P1 (100% pellets), P2 (pellets + Lactobacillus rhamnosus 100 mg%), P3 (pellets + 100 mg astaxanthin), P4 (pellets + combination of L. rhamnosus 70% + astaxanthin 30%), and P5 (pellets + combination of 70% astaxanthin + L. rhamnosus 30%). Parameters observed included an increase in body weight and length, survival, gonad maturity level (TKG), gonad maturity index (IKG), and fecundity. The results of the study showed that 100% astaxanthin (P3) supplementation provided the most optimal results in increasing body weight, survival, gonad maturity and fecundity of female B. splendens. Length growth did not show significant differences between treatments, while water quality during the study remained in the optimal range for keeping Betta fish. These findings confirm the potential of astaxanthin as an effective natural supplement in supporting the sustainable reproductive performance of ornamental fish.

Belanti village used to be land before the entry of the palm oil company, which caused the canalization to form a lake or swamp. The company's canalization blocked the flow of a natural river in Ulak Pati, Pampangan sub-district, preventing water from flowing and causing it to pool in what was once open land. The result of this canalization caused changes to the ecosystem in the village of Rawa Belanti, which had an impact on the growth factors of aquatic organisms that formed along with the formation of the lake/swamp. This study focuses on collecting data and information about the growth of cork fish that are found in many communities in rawa belanti through the sampling method. The study was conducted for 4 months with sampling intervals every 10 days. Calculation of length-weight and condition factor used all cork fish caught during the sampling.The growth factors assessed were the correlation between length and weight, and the condition factor of the gourami fish caught in the swamp. Based on the results of the study, the correlation of length and weight growth is negative allometric, which means that weight growth is slower than the growth of fish length. Assessment of the condition factor of cork fish shows an average value of 1, which means that the fish is in good body condition. Water quality assessment was also conducted in order to support growth data.

Catfish is a popular fish to eat for some people in South Sumatra. The market's strong demand for catfish motivates farmers to keep producing them. One of the strategic stages in enhancing community welfare and attending to local needs is empowering the community, particularly the young of Karang Taruna. In order to create human resources for the production of catfish seeds that promote the sustainability of natural resources, this project aims to transfer science, technology, and skills to Karang Taruna. Helping with fish seeding, basic bookkeeping, and marketing advice are the strategies employed. Sungai Lebung Village, Pemulutan Selatan District, Ogan Ilir Regency, was the location of the community service project. The outcomes of this community service project can proceed as planned. The efficacy of the catfish spawning aid program is demonstrated by the up to 80% seed survival rate. Additionally, partners have a basic understanding of bookkeeping and marketing for catfish seeding activities.

This community service initiative, conducted under the Community-Based Empowerment Scheme, aims to enhance the economic independence of the Burai Village Youth Organization (Karang Taruna) through the implementation of biofloc technology in catfish cultivation and the utilization of maggots (Black Soldier Fly larvae) as an alternative feed source. The program was carried out from March to November 2025, comprising several stages: initial exploration, Focus Group Discussions (FGDs), outreach, technical training, and field practice. The training focused on three key aspects: (1) biofloc-based catfish farming, (2) maggot cultivation as a high-protein feed, and (3) basic marketing and bookkeeping strategies. The outcomes showed a significant improvement in the capacity of village youth to manage productive, fisheries-based enterprises. However, challenges remained, including fish mortality rates of up to 30% due to unstable water quality and maggot mortality caused by high environmental temperatures. Corrective measures were implemented through regular water quality monitoring, improved feed management, and better control of maggot rearing conditions. Overall, this program successfully strengthened the technical and managerial skills of Karang Taruna members, fostered an entrepreneurial mindset, and opened up sustainable business opportunities utilizing local resources.
