Pemanfaatan kotoran ternak dengan dosis yang berbeda terhadap pertumbuhan dan biomassa cacing sutra (Tubifex sp.)

Abstract

The purpose of this study was to analyze the use of cattle dung on the growth and biomass of silk worms. The experiment was conducted at Freshwater Aquaculture Center (BPBAT) Tatelu, Tatelu Village, Dimembe Subdistrict, North Minahasa Regency, North Sulawesi Province, about 35 km from Manado city. The media used was pig manure, chicken manure, cow dung, and fine mud added with EM4. The method used was complete randomized design (RAL) with 4 treatments including A. 500 g of pig manure, 500 g of chicken manure 500 g of cow dung, and 500 g of fine mud; B. 600 g of pig manure, 400 g of chicken manure 500 g of cow dung, 500 g of fine mud; C. 700 g of pig manure, 300 g of chicken manure, 500 g of cow dung, 500 g of fine mud; and K (control) was 2000 g of fine mudinand, each with 3 replications. Water quality parameters measured during the study were temperature, pH, DO, nitrate and nitrite. The results showed that there was a very significant effect on growth but not for the value of silk worm biomass. The highest growth was found in treatment A that was 38 g, while for the highest biomass also in treatment A namely 1.5 g / cm3. Water quality parameters during the study were 24.3-25.4° C, pH 7,1-7,3; DO 2.7-5,7 ppm; nitrate 1.1-1.4 ppm; nitrite 0.011-0.201 ppm.Keywords: Cattle dung, growth, biomass, Tubifex sp., aquaculture

Growth and Survival Rate Goldfish (Carassius auratus L.) in Various Dosages of Natural Feed Tubifex sp.

“…Pada fase benih sebaiknya diberi pakan alami dan Tubifex sp. berpotensi sebagai sumber pakan alami karena ukurannya sesuai dengan bukaan mulut benih ikan mas koki (Wenda et al, 2018). Menurut Deftari et al (2015) Tubifex sp.…”

Edukasi Usaha Budidaya Cacing Tubifex sebagai Salah Satu Peluang Ekonomi bagi Masyarakat Desa Lubuk Saban Kecamatan Pantai Cermin Kabupaten Serdang Bedagai

“…Tingginya kandungan gizi cacing Tubifex hasil dari budidaya sangat dipengaruhi oleh media hidupnya selama masa pemeliharaan. Menurut (Wenda, Pangkey, & Mokolensang, 2018), bahwa kombinasi kotoran babi, kotoran ayam, kotoran sapi, dan lumpur halus yang ditambahkan dengan EM4 sebagai substrat budidaya cacing Tubifex terbukti menghasilkan pertambahan berat cacing Tubifex pada hari ke-28. Pemberian kombinasi limbah peternakan dan lumpur halus yang ditambahkan dengan EM4 sebagai pengkayaan pada media substrat cacing Tubifex diharapkan dapat menjadi solusi dalam meningkatkan ketersediaan cacing sutera, disertai dengan peningkatan biomassa cacing yang cukup besar dan juga peningkatan kandungan nutrisinya.…”

Growth Performance of Silkworms (Tubifex sp.) Cultivated Using a Dry Substrate

“…Starting from selecting the type of substrate to be used and the method of cultivation that will be carried out. The selection of the exemplary substrate can be an indicator of the success of silkworm cultivation because the quality and growth of silkworms are strongly influenced by the cultivation substrate used (Wenda et al, 2018). There are also various cultivation methods, such as traditional paddy fields, apartment systems, and multistorey shelving systems (Lestari et al, 2021).…”
