Earthworms meal (Lumbricus sp.) is very prospective as milkfish feed raw materials to substitute fish meal. Type of raw material and the exact composition will generate artificial feed quality with high levels of water stability, desirable, and safe for the fish. The purpose of this study to evaluate the quality of milkfish feed at different levels of fish meal substitution with earthworms (Lumbricus sp.) based on organoleptic, physical, and chemical tests. The treatments tested levels of substitution of fish meal with earthworms meal in artificial feed milkfish, namely: feed A (0%); feed B (34,62%); feed C (65,38%) and feed D (100%). The organoleptic and physical test showed that all the feed has a smooth texture, pungent aroma, and brown in color, with good water stability (rupture velocity ranged from 91,25±1,47 up to 92,87±1,67 minutes and dispersion of solids 11,14±1,55 up to 11,87±1,3%), hardness 84±0,18 up to 84,71±1,24%, sinking velocity 5,07±0,68 up to 5,64±0,17 cm/sec, the level of homogeneity of 81,34±0,17 up to 85,68±1,85%, the allure of 0,62±0,58 up to 0,65±0,12 cm/sec and delicious power of 0,059±0,024 up to 0,067±0,032 g/fish weight/day. The quality of feed is chemically with moisture content ranging from 8,4–9,1%, 16,7–19,46% ash, 31,07–32,37%, protein, 6,67–7,58% fat, crude fiber 7,45–7,87%, NFE (nitrogen free extracts) 35,35–35,48%. Results show that different levels of substitution of fish meal with earthworms meal (Lumbricus sp.) produces the same feed quality and contains nutrients in a range requirement milkfish. Accordingly, earthworms meal (Lumbricus sp.) can be substituted for fish meal in fish milk feed artificial up to 100%.Keywords: substitution, fish meal, earthworms meal (Lumbricus sp.), artificial feed, milkfish

Saline tilapia fish is a result of technology engineering technique that is tolerant with brackish waters and sea with salinity ≥ 20 ppt. The main problem in the development of saline tilapia is the availability of seeds because the resulting synthesis is still low. One effort to overcome the problem of low tilapia salinity this is by providing dissolved organic material such as glucose. Glucose plays an important role as a source of energy for animals including tilapia. The aim of this research is to determine the optimum dose of dissolved glucose to the survival and growth of salt tilapia larvae (Oreochromis niloticus). The research was conducted from March to May 2017 at Brackish Water Aquaculture (BPBAP) Takalar, South Sulawesi. The research container using 25 L plastic volume basin amounted to 15 pieces. The test animals used were 7-day saline tilapia larvae of 0.03 gram sized for 20 days. The glucose used is pure glucose in powder form. The study was designed using a complete randomized design consisting of 5 treatments and each having 3 replications. The five treatments are 0, 50, 100, 150, 200 ppm per day added to the once-daily research container that is the morning. The result of variance analysis showed that soluble glucose administration had significant effect (p <0.01) on the synthesis and growth rate of saline tilapia fish. The highest survival rates and growth rates were achieved at 100 ppm doses of 94.44% and 14.93% / day respectively, while the lowest at doses of 0 ppm were 74.81% and 11.85% / day respectively.Keywords: glucose, salin tilapia, survival, growth rate

Mixed microorganisms consist of bacteria, fungi, yeasts, and molds that produce important enzymes to ferment raw materials, thereby increasing the nutrient content of milkfish feed. This study aims to examine various doses of mix. microorganisms fermented raw materials on growth performance, chemical composition of the body, and hepatosomatic index of milkfish. Milkfish weighing 28.40 ± 0.11 g is kept in hapa of 1 m3 and placed on brackish water ponds. The test feed contains Sargassum sp. and formulated from raw materials fermented with mix. microorganism (control, 10, 15 and 20 mL / 100 g). The experimental results show the relative growth rate (%) and the growth of biomass (g) of milkfish fed with fermented feedstock with a dose of 10 mL / 100 g (122.77 ± 3.00%, and 522.05 ± 12.19 g ), the real feed is higher than the other dose. The fat content, crude fiber, and energy of test fish fed with fermented feedstock with 10, 15, and 20 mL / 100 g doses were significantly lower, while the hepatosomatic index was significantly higher than the control. (91.11-97,78%), protein content and NFE or Nitrogen Free Extracts (66.81 ± 0.41 72.33 ± 0.28% and 0.88 ± 0.38- 2.24 ± 0.92%), hepatic and muscle glycogen (7.16 ± 0.25-7.3 ± 0.31 mg / g and 6.16 ± 0.16, 6.51 ± 0.35 mg / g) were the same in all treatments. Thus, a dose of 10 mL / 100 g feed ingredients is the best dose in fermenting feed ingredients.Keywords: fermentation, milkfish, mix. microorganism, artificial feed, Sargassum sp.

Abstrak Limbah cangkang rajungan yang mencapai 40-60% dari total bobot rajungan selama ini hanya dibuang ke lingkungan sehingga menimbulkan pencemaran di daerah pesisir. Kegiatan pengabdian masyarakat ini bertujuan memberikan edukasi dan pelatihan kepada kelompok nelayan "Mappedeceng" di Desa Lasitae, Kecamatan Tanete Rilau, Kabupaten Barru tentang pemanfaatan limbah cangkang rajungan menjadi kitosan sebagai pengawet alami. Metode pelaksanaan terdiri dari tiga tahapan yaitu persiapan, pelaksanaan (penyuluhan, pelatihan teknologi pengolahan, dan praktik langsung), serta evaluasi melalui pre-post test. Kegiatan dilaksanakan pada 9 Agustus 2025 dengan melibatkan 40 peserta. Hasil evaluasi menunjukkan peningkatan pengetahuan peserta sebesar 38,75% berdasarkan perbandingan skor pre-test (rata-rata 10,575) dan post-test (rata-rata 18,325). Kegiatan praktik pembuatan pengawet alami menunjukkan antusiasme tinggi dari peserta, dengan mayoritas merasa percaya diri menerapkan teknologi ini di rumah. Kitosan yang dihasilkan terbukti dapat memperpanjang masa simpan produk perikanan hingga 2-3 kali lipat dan memiliki nilai ekonomi tinggi sekitar Rp 75.000-100.000 per kilogram. Program ini berhasil meningkatkan kesadaran nelayan tentang pentingnya ekonomi sirkular dalam perikanan dan memberikan solusi berkelanjutan untuk mengatasi masalah limbah cangkang rajungan sekaligus menciptakan peluang ekonomi baru bagi masyarakat pesisir. Kata kunci: limbah cangkang rajungan; kitosan; pengawet alami; pemberdayaan nelayan; teknologi pengolahan limbah. Abstract Crab shell waste, which accounts for 40-60% of the total weight of crabs, is often dumped into the environment, causing pollution in coastal areas. This community service activity aims to provide education and training to the "Mappedeceng" fishing group in Lasitae Village, Tanete Rilau District, Barru Regency, on the utilization of crab shell waste into chitosan as a natural preservative. The implementation method consists of three stages: preparation, implementation (counseling, processing technology training, and direct practice), and evaluation through a pre-post test. The activity was carried out on August 9, 2025, involving 40 participants. The evaluation results showed an increase in participant knowledge of 38.75% based on a comparison of pre-test scores (average 10.575) and post-test (average 18.325). The practical activity of making natural preservatives showed high enthusiasm from the participants, with the majority feeling confident in applying this technology at home. The resulting chitosan has been proven to extend the shelf life of fishery products by two to three times and has a high economic value of around IDR 75,000-100,000 per kilogram. This program has successfully raised awareness among fishermen about the importance of a circular economy in fisheries and provided a sustainable solution to address the problem of crab shell waste while creating new economic opportunities for coastal communities. Keywords: crab shell waste; chitosan; natural preservative; fishermen empowerment; waste processing technology.
