Abstract

Penelitian ini bertujuan mengevaluasi pengaruh kombinasi pakan pelet komersial dan Wolffia arrhiza terhadap performa pertumbuhan benih ikan nila salin (Oreochromis niloticus) pendederan II. Metode penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan rasio pelet dan wolffia: Kontrol (100:0), A (85:15), B (75:25), dan C (65:35). Hasil menunjukkan bahwa pemberian pakan kombinasi berpengaruh nyata (P < 0,05) terhadap pertumbuhan bobot mutlak dan pertumbuhan panjang mutlak, namun tidak berpengaruh nyata (P > 0,05) terhadap laju pertumbuhan spesifik (SGR). Penurunan performa pertumbuhan pada pakan kombinasi dibandingkan kontrol diduga akibat hambatan serat kasar (selulosa) dinding sel wolffia serta pengalihan energi pakan untuk proses osmoregulasi di media payau (6 ‰) dan adaptasi terhadap fluktuasi amonia (0,4-0,8 mg/l). Rasio konversi pakan (FCR) cenderung meningkat seiring bertambahnya proporsi wolffia, dengan nilai terbaik pada Kontrol (1,5) diikuti Perlakuan A (2,4). Meskipun terjadi penurunan efisiensi pakan, tingkat kelangsungan hidup tetap stabil dan tidak berbeda nyata pada kisaran 79-88%. Penelitian menyimpulkan bahwa Perlakuan A (substitusi 15% wolffia) merupakan dosis paling efektif yang mampu menyokong pertumbuhan dengan performa panjang mutlak yang secara statistik setara dengan kontrol, sehingga berpotensi sebagai alternatif pakan pendorong efisiensi biaya.

Abstract

Vaname shrimp (Litopenaeus vannamei) has a fast growth rate, good tolerance to a wide range of salinity and temperature, and resistance to several common shrimp diseases. Vaname shrimp has an efficient feed conversion making it more economical to cultivate, and its international market demand is high. The research method used four treatments of fermented soybean meal doses, namely 0% (control), 15%, 25%, and 35%, each with 3 replications. The feed was formulated using Pearson’s Square method targeting 35% protein, and the soybean meal was fermented using tempe yeast method. The observed parameters included daily growth rate (%), absolute weight gain (grams), survival rate (%), feed utilization efficiency (FUE), and feed conversion ratio (FCR). The results showed that the treatment with 25% fermented soybean meal dose gave the best results with a daily growth rate of 6.42%, absolute weight gain of 0.22 grams, survival rate of 90.66%, and the highest feed utilization efficiency of 0.66.
ANALISIS KELAYAKAN USAHA TEKNIK BUDIDAYA RUMPUT LAUT (Gracilaria sp) YANG BERBEDA PADA TAMBAK TRADISIONAL DI DESA RANDUSANGA KULON KABUPATEN BREBES Guntur Bayu Samudra; Nurjanah; Ninik Umi Hartanti

Abstract

Rumput laut merupakan salah satu komoditas perikanan yang memiliki nilai ekonomis tinggi dan berperan penting dalam mendukung ketahanan pangan serta perekonomian masyarakat pesisir. Teknologi budidaya menentukan produktivitas budidaya dan kelayakan usaha budidaya yang dilakukan. Penelitian ini bertujuan untuk mengetahui kelayakan usaha serta mengevaluasi teknik budidaya rumput laut (Gracilaria sp) pada tambak tradisional di Desa Randusanga Kulon, Kecamatan Brebes, Kabupaten Brebes. Pertumbuhan rumput laut metode terapung menghasilkan bobot tertinggi dibandingkan metode lepas dasar dan metode dasar. Analisis kelayakan usaha menunjukkan bahwa budidaya rumput laut di lokasi penelitian secara finansial layak untuk dikembangkan. Total biaya produksi per tahun berkisar antara Rp49.980.000 hingga Rp76.445.000, dengan rata-rata keuntungan yang diperoleh petani sebesar Rp24.864.000 hingga Rp53.587.000 per tahun. Nilai Revenue Cost Ratio (R/C Ratio) seluruh responden berada di atas 1, yakni pada kisaran 1,48 hingga 1,70, yang mengindikasikan bahwa usaha budidaya rumput laut layak dilakukan. Secara keseluruhan, usaha budidaya rumput laut Gracilaria sp. pada tambak tradisional di Desa Randusanga Kulon memiliki prospek yang baik dan dapat dijadikan sumber pendapatan utama bagi masyarakat pesisir setempat. Penerapan metode terapung serta pengelolaan kualitas air yang optimal merupakan sebagai upaya untuk meningkatkan produktivitas dan keberlanjutan usaha budidaya di wilayah tersebut

Abstract

Tilapia (Oreochromis niloticus) It is one of the freshwater fish that has received considerable attention from the government which is expected to contribute to increased production. In doing fish farming business, it is hoped that fish can grow faster. One effort to accelerate the growth of Tilapia (Oreochromis niloticus) by adding supplementation to the feed. One of the supplementations that can be used Azolla. addition of Azolla supplementation (Azolla microphylla) can affect the process of growth and development of Tilapia (Oreochromis niloticus). Knowing the effect of dosing Azolla (Azolla microphylla) which is effective against the growth of Tilapia (Oreochromis niloticus). The method used in the study was an experimental method of 3 treatments using Complete Random Design (RAL), each treatment had 3 repetitions, each of which consisted of 10 TilapiaS (Oreochromis niloticus). The fish to be used in this study are Tilapia (Oreochromis niloticus) fry with a length of between 5-7 cm. As an additional feeding treatment Azolla (Azolla microphylla) supplementation with treatment doses A (20 gr), B (30 gr), C (40 gr) and control (0 cm). The results showed that each treatment differed markedly on growth and survival rates. Treatment C is the best treatment at growth of 8.9 g and daily growth rate of 0.319 gr, Tilapia (Oreochromis niloticus) fry survival in A, B, C and Control is relatively stable with a survival percentage of 100%. Water quality during the study was within a decent range for Tilapia (Oreochromis niloticus) life.
