Abstract

Ikan komoditas lokal yang memiliki potensi untuk dibudidayakan salah satunya adalah ikan baung, karena ikan jenis ini juga memiliki nilai ekonomi yang tinggi. Tujuan pengabdian kepada masyarakat adalah untuk meningkatkan minat masyarakat gunung manau untuk melakukan usaha pembenihan ikan baung dan meningkatkan mutu benih ikan baung. Pengabdian dilaksanakan di Balai Benih Ikan Lokal Gunung manau yang berada di desa Gunung manau, kecematan Batu mandi, kabupaten Balangan kegiatan dilaksanakan dari bulan April – Mei 2024. Bentuk kegiatan yang dilakukan ialah dengan praktek langsung ke lapangan dan melakukan wawancara pada pihak BBIL Gunung manau. Metode yang digunakan ialah kualitatif deskriftif. Hasil pelatihan yang dilakukan diketahui bahwa Melalui pemijahan secara buatan pada ikan baung yang dilakukan pada budidaya ikan baung di BBIL Gunung Manau menghasilkan benih yang berjumlah 70.000 ekor. Meskipun perlu perhatian khusus dalam pemeliharaan dari ukuran larva sampai benih karena sifatnya yang rentan mudah mati jika kekurangan oksigen sehingga aerasi harus selalu menyala untuk menghindari kematian massal.

Abstract

Abstract. Research and development of biofloc aquaculture system until now only in the range of 14-15 species conducted. Even though this technology is able to increase production several times compared to conventional systems, so it is necessary to diversify species that allow development, especially economically important fish. There are 4 species of fish that are feasible to be developed, especially freshwater fish groups in wetlands, such as fish (climbing perch; Anabas testudineus Bloch, snakehead, Channa striata Bloch, giant gouramy , Opronemus gouramy and Pangas , Pangasius hypophthalmus. This research has been carried out in the range of June 2023- February 2024 using a complete randomised complete block design, 4 treatments climbing perch; snakehead, giant gouramy and pangas with 4 replicates. Stocking density of 1000 fish 2500 L-1 using 2 m diameter round pond with biofloc media; feeding twice a day and the amount of feed given was 2.5% of total weight, for 158 days. Research parameters included; daily growth rate (%/day), feed efficiency. FCR, weight gain (gr) and length gain (cm), water quality and biofloc content (ml/L). The results showed that the results of the anova test showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments of the daily growth rate (SGR) parameter, the results of the area test also showed differences between treatments. The highest daily growth rate was obtained in climbing perch, followed by pangas, giant gouramy and Snakehead. The results of the anova test for weight gain showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments. The anova test results showed a significance value (Sig.) of 0.052 0.005, so there was no significant difference between treatments; the growth of each treatment showed peculiarities between species depending on genes. Anova test results show that the feed conversion of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system Survival rate of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system. Water quality with 4 main parameters is able to support the growth and development of the 4 economically important fish species studied.

Abstract

The quality of the river will undergo changes in accordance with the development of the river environment which is influenced by various activities and human life. This study aims to analyze the status of water quality in the Kanibungan River based on a comparison of quality standards and water quality index with the pollution index method and river water pollution control strategies. Measurement of research parameters at three locations, namely the upstream, middle, and downstream of the Kanibungan River. Insitu sampling and laboratory tests. Water quality parameters are TSS, pH, BOD5, DO, Mn, H2S, Fat and Oil. Quality standards based on South Kalimantan Governor Regulation No. 5 of 2007 class I water quality classification and KAN accredited Parameters (ISO/IEC 17025). The pollution index is based on the Decree of the Minister of Environment No.115 of 2003. The results of the research on water quality compared to class I water quality standards for parameters, TSS, pH, dissolved oxygen, Fe, Mn, H2S and oils and fats meet the quality standards, water quality BOD5 exceeds the quality standard. The water quality status of the upstream, middle and downstream of the river is included in the slightly polluted category with a value range of 2.5213-2.5507. River pollution control strategies can be carried out by reducing pollution loads, namely by community-based river environmental management, involving supervision from the local government.
