Abstract

Tubifex worms are freshwater oligochaetes characterized by their bright red color and high nutritional content, consisting of 57% protein, 13.3% fat, 2.04% crude fiber, and 3.6% ash. Their natural populations have declined due to water pollution from waste, which reduces water quality, thus necessitating cultivation efforts. This study aimed to evaluate the effect of fermented sawdust and cocopeat as culture substrates on the biomass, population, and growth rate of Tubifex worms. The experiment was conducted using a Completely Randomized Design (CRD) with a non-factorial model consisting of four treatments and three replications: A (control: 80% mud + 20% chicken manure), B (80% fermented sawdust + 20% chicken manure), C (80% fermented cocopeat + 20% chicken manure), and D (40% fermented sawdust + 40% fermented cocopeat + 20% chicken manure). Analysis of variance (ANOVA) showed that different substrate compositions had a significant effect on biomass, population peak, and growth rate. The best performance was observed in treatment B, which resulted in the highest biomass (13.32 g/container), the highest population peak (120,111 individuals/container on day 40), and the highest growth rate (3.09%). These results indicate that fermented sawdust supplemented with chicken manure is the most effective substrate for enhancing the growth and population of Tubifex worms.

Abstract

Usaha budidaya perikanan merupakan sebuah usaha pemeliharaan ikan mulai dari pembenihan, pemeliharaan, pemberian pakan sampai pemasaran ikan. Dalam usaha budidaya ikan tidak terlepas dari pakan ikan, karena pakan merupakan biaya terbesar dalam produksi mencapai 60- 70% dari biaya produksi ikan. Pakan ikan selama ini memiliki kendala salah satunya yaitu harga pakan yang tinggi yang tidak mengimbangi harga jual ikan sehingga pembudidaya merasa kewalahan dalam hal pakan ikan, apalagi pakan dengan protein tinggi sudah pasti harganya jauh lebih mahal dibandingkan dengan pakan dengan protein rendah. Metode pendekatan dalam kegiatan pengabdian ini adalah metode edukatif, partisipatif, dan persuasif. Prosedur kegiatan pengabdian kepada masyarakat ini terdiri atas beberapa tahapan, yakni: (1) Penyuluhan tentang pakan ikan buatan berbahan baku limbah, (2) penyuluhan tentang pengenalan berbagai bahan baku limbah yang berpotensi untuk dijadikan bahan pakan, (3) penyuluhan tentang teknologi pembuatan pakan ikan, (4) pelatihan dalam tahapan pembuatan pakan ikan. Hasil yang dirasakan adalah terjadi perubahan tambahan pengetahuan dan pengalaman serta skil peserta pengabdian tentang pemanfaatan bahan baku limbah untuk pembuatan pakan ikan mandiri.

Abstract

Socialization of service is aimed at salt farmers in developing geomembrane technology for smallholder salt businesses in accordance with local resource conditions and capacities, potential and capacity for salt development and marketing, and the availability of technology to increase sales of salt based on information technology, as well as technical management capabilities in one management. The problem with salt farmers is mostly coastal communities which are identical with helplessness, poverty and backwardness, especially from the socio-economic aspect. Traditional production technology, small production scale, and limited marketing and promotion strategies cause the products they produce are still far from prosperous due to low income. The low income of salt farmers makes it difficult for salt farmers to implement innovations and increase the productivity of salt farmers in various regions. The objectives of implementing science and technology activities for the community (PKM) are, firstly, geomembrane technology to increase the resource capacity of salt farmers in an effective and efficient manner, secondly to increase sales marketing results of salt production, thirdly to increase sales significantly through information technology promotion media, fourthly to create shelters. Ergonomically salt in Kuala Cangkoy, Lapang District. The specifications of the socialization results from community service produced can achieve economies of scale and be able to have salt carried out in an integrated manner in the marketing management system. Have a strong bargaining position in the market, both the primary product market and its derivative products based on information technology technology. The last is being able to increase the income of partner members collectively from the results of storing salt because the place is built according to ergonomic principles and from a marketing perspective.
