Abstract

ABSTRAK Lobster air tawar (Cherax quadricarinatus) merupakan komoditas air tawar yang potensial untuk dibudidayakan. Harga jual yang relatif tinggi, sampai saat ini permintaan pasar lobster air tawar baik dalam keadaan hidup maupun beku cukuplah besar. Pertumbuhan lobster air tawar ditunjang oleh ketersediaan pakan dalam jumlah yang cukup. Saat ini, melonjaknya harga pakan menimbulkan dilema bagi pembudidaya. Salah satu alternatif untuk menekan biaya produksi adalah dengan memanfaatkan pakan alternatif. Tujuan penelitian ini adalah untuk mengetahui kombinasi pakan alternatif nabati dan hewani manakah yang cocok untuk menghasilkan pertumbuhan benih lobster air tawar yang optimal. Metode penelitian yang digunakan adalah penelitian eksperimental. Desain yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 (lima) perlakuan. Perlakuan terdiri dari; Perlakuan (A) Pakan Alternatif Nabati (100%) + Pakan Alternatif Hewani (0%), Perlakuan (B) Pakan Alternatif Nabati (75%) + Pakan Alternatif Hewani (25%), Perlakuan (C) Pakan Alternatif Nabati (50%) + Pakan Alternatif Hewani (50%), Perlakuan (D) Pakan Alternatif Nabati (25%) + Pakan Alternatif Hewani (75%), Perlakuan (E) Pakan Alternatif Nabati (0%) + Pakan Alternatif Hewani (100%). Benih LAT yang digunakan memiliki berat awal 10 gr degan panjang 12 cm. Parameter uji adalah pertumbuhan berat mutlak pada benih LAT yang dihitung pada awal dan akhir penelitian, serta disampling setiap minggu. Data yang diperoleh selama penelitian dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa Perlakuan D (Pakan Nabati 25% + Pakan Hewani 75%) menghasilkan pertumbuhan berat mutlak tertinggi sebesar 10 gram.Kata kunci: lobster air tawar, pakan alternatif, kombinasi pakan, berat mutlak.ABSTRACTFreshwater lobster (Cherax quadricarinatus) is a freshwater commodity that has potential for cultivation. The selling price is relatively high, so currently the market demand for freshwater lobsters, both live and frozen, is quite large. The growth of freshwater lobsters is supported by the availability of sufficient amounts of food. Currently, soaring feed prices are creating a dilemma for farmers. One alternative to reduce production costs is to use alternative feed. The aim of this research is to find out which combination of alternative plant and animal feeds is suitable for producing optimal growth of freshwater lobster seeds. The research method used is experimental research. The design used was a Completely Randomized Design (CRD) with 5 (five) treatments. Treatment consists of; Treatment (A) Vegetable Alternative Feed (100%) + Animal Alternative Feed (0%), Treatment (B) Vegetable Alternative Feed (75%) + Animal Alternative Feed (25%), Treatment (C) Vegetable Alternative Feed (50% ) + Animal Alternative Feed (50%), Treatment (D) Vegetable Alternative Feed (25%) + Animal Alternative Feed (75%), Treatment (E) Vegetable Alternative Feed (0%) + Animal Alternative Feed (100%). The LAT seeds used had an initial weight of 10 grams with a length of 12 cm. The test parameter is the absolute weight growth of LAT seeds.Key words: freshwater lobster, alternative feed, combination of feed, absolute weigh.

Abstract

The use of probiotics is very important in cultivation activities. Probiotics are live microorganisms that have a beneficial effect on the host by balancing the microflora in their intestines. In increasing the nutritional content of artificial feed (pellets), the bacteria in probiotics have a mechanism for forming several enzymes for digesting feed. This study aims to determine the effect of giving delacto probiotics at different doses in artificial feed on the absolute weight growth of tilapia (Oreochromis niloticus). Probiotics are mixed with feed using a biofloc cultivation system. The method used in this research was an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 6 replications, namely by adding different doses to the treatments. Treatments A (8ml/kg), B (16 ml/kg), C (24 ml/kg) and D (32 ml/kg). The parameter observed was absolute weight growth. Water quality supporting parameters include temperature, pH and DO. Data were analyzed using the ANOVA test. Based on the research results, it shows that giving different doses of delacto probiotics has a significant effect on the absolute weight growth of tilapia (Oreochromis niloticus). Treatment A (8 ml/kg) gave the lowest absolute weight growth of 32.83 grams and treatment D (32 ml/kg) gave the highest absolute weight growth of 40.57 grams. Water quality parameters include water temperature ranging from 25.3 – 26.1֯C, acidity ranging from 7.5 – 8.0. And dissolved oxygen ranges from 4.7 – 5.3 ppm. The results of analysis of variance (ANOVA) for the three water quality parameters showed no differences between treatments (Oreochromis niloticus) fry.
