Abstract

Masalah yang sering dihadapi dalam produksi benih adalah tingginya tingkat kematian larva atau tingkat kelulusan hidup yang masih rendah. Penelitian ini tentang pemberian dosis minyak cumi yang berbeda pada permukaan air untuk mengetahui dosis terbaik terhadap tingkat kelangsungan hidup larva kakap putih (L. calcarifer). Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 kali ulangan yaitu K: Tanpa minyak cumi, A: Minyak cumi 0,1 ml/m2, B: Minyak cumi 0,2 ml/m2, C: Minyak cumi 0,3 ml/m2, D: Minyak cumi 0,4 ml/m2. Analisis data menggunakan One-Way ANOVA dan uji lanjut duncan menunjukkan tingkat kelulusan hidup terbaik terjadi pada perlakuan C (24,53±2,66%), panjang mutlak terbaik terjadi pada perlakuan A (1,16 ± 0,04) cm. Hasil penelitian yang diperoleh menunjukkan perlakuan C merupakan perlakuan terbaik.

Abstract

This research was carried out from April to June 2021 in Madong Village, Bugis Village, Tanjungpinang City. The purpose of this study was to determine the effect of adding turmeric flour to feed on the growth of cantang grouper. This study used a completely randomized design method with 4 treatments with each treatment repeated 3 times, namely treatment K (without the addition of turmeric flour), treatment A (addition of 10 g of turmeric flour to 1 kg of feed), treatment B ( addition of 15 g of turmeric flour to 1 kg of feed), treatment C (addition of 20 g of turmeric to 1 kg). The results showed that treatment B (addition of turmeric flour 15 g to 1 kg of feed) was the highest treatment for all parameters which included absolute weight growth value of 53.37 g, daily growth rate of 1.19gr/day, feed efficiency 71.48%. However, it was not significantly different from treatment A (addition of 10 g of turmeric flour to 1 kg of feed) which included an absolute weight growth value of 51.66 g, daily growth rate of 1.15 g/day, feed efficiency 65.55%. So, the addition of 10 g of turmeric flour to 1 kg of feed was effective for the growth of Epinephelus foscoguttatus x Epinephelus lanceolatus grouper.

Abstract

This study aims to determine the optimal temperature range of rearing media for the growth and survival of barramundi larvae. This research was conducted in the biology laboratory of the Faculty of Marine Sciences and Fisheries, Raja Ali Haji Maritime University. The test fish used were 3 day old white snapper larvae which were kept in 13 aquariums where one aquarium was specifically for organ observation. The aquarium used is 25x25x35 cm filled with 10 liters of water with a density of 5 fish/liter. The temperature treatments were P1 (26°C), P2 (28°C), control (30°C), and P4 (32°C) with 3 replications. The design used was a completely randomized design. Larvae were fed rotifers using the abliditum method with a frequency of 3 times a day. The results showed that the white snapper larvae produced a length growth rate and survival rate of 4.99 mm and 28,67 % at an optimal temperature of 32°C.

Abstract

Ikan kerapu cantang (Epinephelus fuscoguttatus x Epinephelus lanceolatus) di Indonesia sedang dikembangkan dan digalakkan sebagai komoditas budidaya laut unggulan untuk diekspor dengan nilai yang cukup tinggi. Harga ikan kerapu berkisar antara Rp. 110.000- 120.000/kilogram. Pembudidaya umumnya memberikan pakan pada ikan budidaya hanya menurut kebiasaannya, tanpa mengetahui tentang kebutuhan. Salah satu usaha yang dapat dilakukan dalam usaha budidaya untuk mendukung tingkat keberhasilan budidaya salah satunya dengan cara pengaturan frekuensi pemberian pakan. Sehingga perlu dilakukan penelitian lebih lanjut tentang frekuensi yang tepat untuk dapat mengoptimalkan pertumbuhan ikan kerapu cantang. Penelitian ini dilaksanakan pada bulan Oktober -November 2020 di Kelompok Budidaya Maju Mandiri, Kelurahan Kampung Bugis, Kota Tanjungpinang, Kepulauan Riau. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan yaitu A : 1 kali/hari, B : 2 kali/hari, C : 3 kali /hari, D : 4 kali/hari. Analisis data menggunakan One-Way ANOVA dan uji lanjut Duncan. Hasil analisis data menunjukan bahwa nilai FCR, EP, BM, PM, SGR terbaik terjadi pada perlakuan D dengan nilai FCR (2,25±0,02), EP (44,49±0,36 %), BM (26,8±0,28 g), PM (5,0±0,35 cm), SGR (0,638±0,006g/hari).

Abstract

The research was carried out in September 2021, taking place at the Marine Aquaculture Laboratory and for water quality analysis carried out at the Marine Chemitry Laboratory of the Raja Ali Haji Maritime University, Tanjungpinang City, Riau Islands Province. The method used is an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications. The results showed that the levels of ammonia and nitrite decreased after passing through the coconut shell charcoal fragments. The best reduction in ammonia and nitrite levels was obtained in treatment C (using coconut charcoal fragments of 30 g/liter of rearing container water), resulting in total ammonia nitrogen of (11,983±0.691) and nitrite (4.14±0.01), the length of time for filter performance for 2 days the level of ammonia (0.115±0 ppm) and nitrite level of (4.448±0)

There are several factors that will inhibit the growth of seaweed when the cultivation process is the initial stocking density in the off-bottom method. This study aims to determine the effect of different awa seed weights on the growth rate of K. alvarezii seaweed which will provide information regarding the optimal initial weight. This research was carried out in April-May 2021 for 42 days with an acclimatization period of 3 days and preparation of containers for 7 days. Berakit Village, Teluk Sebong District, Bintan Regency, Riau Islands Province. The method used is an experimental method with a completely randomized design (CRD) with 3 treatments with 3 replications. Where the weight of the seeds of treatment A: 50 g, B 100 g, C 150 g, The results of the analysis of the highest absolute growth were obtained in seaweed with initial seed weight of 50 treatments. g with the highest average value of 207.75±9.02b, followed by treatment of 150 g with an average value of 166.78±6.96a and the lowest treatment of 100 g with an average value of 157.04±1.48a. Meanwhile, the highest daily specific growth rate was focused on the 50 g treatment with an average value of 4.95±0.22% b followed by the 150 g treatment with an average value of 3.97±0.17% and the lowest treatment was in the 100 g treatment with an average value of 3.74± 0.04%.
