Abstract

Abstrak. Tingginya biaya pakan, yang mencapai hingga 70–90% dari total biaya operasional, menjadi tantangan utama bagi pembudidaya ikan di Desa Panakkukang dan berdampak langsung pada keberlanjutan usaha mereka. Program pengabdian kepada masyarakat ini bertujuan untuk memberikan solusi inovatif dan berkelanjutan melalui pemanfaatan limbah pengolahan tuna (Thunnus sp.) dan rajungan (Portunus pelagicus) sebagai bahan dasar biostarter untuk fermentasi pakan ikan. Kegiatan dilaksanakan melalui beberapa tahapan, yaitu pelatihan pembuatan biostarter, pelatihan produksi pakan ikan berbahan limbah perkebunan dan pertanian, produksi biostarter secara mandiri, proses fermentasi pakan, serta aplikasinya dalam kegiatan budidaya oleh anggota kelompok pembudidaya ikan (pokdakan). Peserta pelatihan mencakup anggota Pokdakan Parannuanta, GAPOKTAN, mahasiswa KKN, dan aparat desa. Hasil program menunjukkan bahwa peserta berhasil menguasai teknik produksi biostarter dan pakan fermentasi, serta mampu memproduksinya secara mandiri dengan memanfaatkan bahan baku lokal. Uji aplikasi pakan fermentasi pada kolam budidaya memperlihatkan peningkatan efisiensi pakan, percepatan pertumbuhan ikan, dan penurunan biaya operasional secara signifikan dibanding penggunaan pakan komersial. Selain meningkatkan produktivitas pembudidaya, inovasi ini mendorong pengelolaan limbah industri perikanan dan pertanian secara ramah lingkungan. Secara keseluruhan, kegiatan ini berkontribusi terhadap peningkatan kapasitas pembudidaya, keberlanjutan ekonomi rumah tangga, dan ketahanan pangan masyarakat lokal. Keberlanjutan program direkomendasikan melalui penyusunan panduan teknis dan replikasi secara lebih luas pada kelompok pembudidaya di wilayah lain. Kata Kunci: Biostarter, Limbah tuna dan rajungan, Pakan ikan fermentasi, Pembudidaya ikan (Pokdakan)

Abstract

This study investigates the synergistic effects of honey and coconut water as natural masculinization agents on Nile tilapia (Oreochromis niloticus) larvae. The experiment evaluated the impact of these natural substances on sex ratio, hatchability, growth performance, and survival rate. A total of four treatments were tested: honey (15 ml/L), coconut water (30%), a combination of both, and a control group. Results showed that the combination of honey and coconut water yielded the highest masculinization ratio (94%), significantly higher than the control group (53%). Additionally, the combination treatment also exhibited superior hatchability (77.5%) and growth performance compared to the other treatments. Survival rates were highest in the combination group (94.67%), followed by coconut water (88.67%), honey (87.33%), and control (73.67%). This study provides promising evidence that honey and coconut water can be used as sustainable, eco-friendly alternatives to synthetic hormones in tilapia aquaculture.

Abstract

This study aims to analyze the effect of the use of water hyacinth (Eichhornia crassipes) fermented with tuna waste (Thunnus albacares) on the growth, feed efficiency, and survival of tilapia (Oreochromis niloticus). Fermentation is carried out using Lactobacillus sp. and Saccharomyces cerevisiae for five days in anaerobic conditions at 35°C. A complete randomized design was used with four fermentation dose treatments (0, 10, 20, and 30 ml/kg feed) as well as three replicas. The results showed that a fermentation dose of 20 ml/kg resulted in the highest absolute weight growth (167.6 ± 11.24 g), the best specific growth rate, the lowest feed conversion ratio (FCR) (0.81), and the highest survival rate (93.3 ± 1.92%). Excessive fermentation doses (30 ml/kg) reduce feed digestibility due to increased crude fiber. Statistical analysis showed a significant influence (p < 0.05) between treatment on growth and feed efficiency. The results indicate that fermentation of fish stomach waste at moderate doses can increase the nutritional value of water hyacinth and support the concept of zero waste aquaculture using environmentally friendly local materials

Abstract

Water quality is a critical factor influencing the growth and productivity of seaweed cultivation. This study aimed to analyze the relationship between water quality characteristics and the productivity of Kappaphycus alvarezii cultivated using the long-line method in West Sebatik District, Nunukan Regency. The study was conducted from September to December 2025 in three villages, namely Setabu, Binalawan, and Liang Bunyu, using a quantitative approach with an observational and descriptive-analytical design. Water quality parameters measured included temperature, salinity, pH, dissolved oxygen, transparency, current velocity, depth, nitrate, and phosphate. Productivity was evaluated based on growth performance and annual production. The results indicated that all water quality parameters were generally within suitable ranges for seaweed cultivation. Binalawan exhibited the highest transparency (1.50 ± 0.15 m) and phosphate concentration (0.30 ± 0.06 mg L⁻¹), resulting in the highest biomass (388 g) and specific growth rate (4.182% day⁻¹). Liang Bunyu recorded the highest annual dry production (6,435 tons year⁻¹) due to its larger cultivation area. The findings highlight the importance of water quality management and site selection in improving the productivity and sustainability of K. alvarezii cultivation
