Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dosis ragi roti yang berbeda terhadap kepadatan rotifera (Brachionus plicatilis). Penelitian ini dilakukan pada bulan Agustus 2021 di Laboratorium Perikanan Terpadu, Universitas Sulawesi Barat. Rotifera dikultur dengan pemberian pakan alami Nannochloropsis sp. sebanyak 41 ml dengan penambahan berbagai dosis ragi roti. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu perlakuan A sebagai kontrol yakni penambahan ragi roti dengan dosis 0,0 mg/L, perlakuan B dosis 15,0 mg/L, perlakuan C dosis 30,0 mg/L, dan perlakuan D dosis 45,0 mg/L. Parameter yang diujikan yaitu kepadatan rotifera. Analisis data menggunakan ANOVA dengan tingkat kepercayaan 95%. Hasil uji ANOVA menunjukkan bahwa pemberian pakan ragi roti dengan dosis yang berbeda memberikan pengaruh nyata (P<0,05) terhadap kepadatan rotifera pada hari ke-3 sampai hari ke-5 pemeliharaan. Kepadatan rotifera tertinggi diperoleh pada perlakuan B yakni pemeliharaan hari ke-4 dengan pakan ragi roti sebanyak 15,0 mg/L yaitu 3.999.333 ind/L, kemudian di ikuti perlakuan A (kontrol) yakni 2.999.667 ind/L, perlakuan C yakni 2.583.000 ind/L dan terendah pada perlakuan D yaitu 2.249.667 ind/L. A B S T R A C T The present study aimed to determine the effect of different doses of baker's yeast on the density of rotifers (Brachionus plicatilis). This study was conducted in August 2021 at the Integrated Fisheries Laboratory, West Sulawesi University. Rotifers were cultured with natural feed Nannochloropsis sp. with a density of 41 ml with the addition of various doses of baker's yeast. Completely Randomized Design (CRD) with 4 treatments and 3 replications, treatment was used for experimental design with the addition of baker's yeast at a dose of 0.0 mg/L, treatment B with 15.0 mg/L dose, treatment C at a dose of 30.0 mg. /L, and treatment D with 45.0 mg/L doses. The parameter tested is the density of rotifers. Data analysis used ANOVA with a 95% confidence level. The results of the ANOVA test showed that the feeding of baker's yeast with different doses had a significant effect (P<0.05) on the maintenance of the density of rotifers on the 3rd to 5th day. The highest density of rotifers was obtained in treatment B, rotifers maintenance on the 4th day with 15.0 mg/L yeast feed, which was 3,999,333 ind/L, then followed by treatment A (control) which was 2,999,667 ind/L), treatment C namely 2,583,000 ind/L and the lowest in treatment D was 2,249,667 ind/L.

Abstract

Uji coba budidaya rumput laut Codium sp. dengan bobot bibit berbeda pada media penumbuhan berupa limbah cair tambak udang super intensif. Penelitian ini bertujuan untuk menganalisis kemampuan rumput laut Codium sp. dalam menyerap unsur nitrogen dan fosfor dari media budidaya udang. Penelitian dilakukan selama 45 hari di Instalasi Tambak Percobaan (ITP) Balai Penelitian dan Pengembangan Budidaya Air Payau (BPPBAP), Desa Punaga, Kecamatan Mangarabombang, Kabupaten Takalar. Wadah yang digunakan adalah kotak plastik berukuran 87 cm x 64 cm dengan ketinggian air di dalam wadah 40 cm. Penelitian terdiri atas 4 perlakuan bobot Codium sp. yaitu A (50 g), B (100 g), C (50 g) dan D (200 g) dan masing-masing perlakuan diulang sebanyak tiga kali. Analisis data menggunakan ANOVA dengan tingkat kepercayaan 95% dan uji lanjut W-Tuckey menggunakan perangkat lunak SPSS versi 23. Hasil penelitian menunjukkan adanya pengaruh penyerapan yang dilakukan oleh rumput laut Codium sp. dengan bobot bibit 200 g yang menghasilkan laju penyerapan N-total tertinggi 0.1133±0.01155% sedangkan laju penyerapan P-Total tertinggi yaitu pada bobot 100 g dengan nilai 0.00500±0.002646%. A B S T R A C T Cultivation of Codium sp. seaweed with different seed weights on the growth media in the form of super intensive shrimp pond liquid waste is a promising method for seaweed aquaculture. The study was conducted for 45 days at the Experimental Pond Installation (ITP) Research and Development Center for Brackish Water Aquaculture (BPPBAP), Punaga Village, Mangarabombang District, Takalar Regency. A plastic box is used by the container in this research measuring 87 cm x 64 cm with a water level of 40. The study consisted of 4 weight treatments of Codium sp. namely A (50 g), B (100 g), C (50 g) and D (200 g) and each treatment was repeated three times. Data of research is analyzed by ANOVA with a 95% confidence level and further W-Tuckey test using SPSS version 23 software. The results showed that there was an effect of absorption by seaweed Codium sp. with a seed weight of 200 g resulting in the highest N-total absorption rate of 0.1133±0.01155%, while the highest P-Total absorption rate was at a weight of 100 g with a value of 0.00500±0.002646%.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui komposisi hasil tangkapan bagan perahu di Desa Tonyaman Kab. Polewali Mandar. Penelitian ini dilaksanakan pada tanggal 8-19 April 2023 di Desa Tonyaman dengan menggunakan metode deskriptif yaitu membuat gambaran atau deskripsi mengenai komposisi hasil tangkapan bagan perahu. Hasil pengamatan penelitian yang berlangsung selama 10 trip didapatkan volume persentasi hasil tangkapan tertinggi yaitu jenis ikan teri (Stolephorus sp.) sebesar 61% (789 kg) dan terkecil adalah ikan semar (Mene maculate), sebesar 0,07% (0,85 kg). Analisa frekuensi kemunculan ikan, menunjukkan ikan teri (Stolephorus sp.) lebih sering tertangkap dengan persentasi sebesar 90% sedangkan ikan semar (Mene maculate) memiliki persentasi tertangkapnya paling kecil yaitu sebesar 10%.

Abstract

The success of the tiger prawn seeding business is the first step in the cultivation chain system that will support the business of providing quality seeds. One of the factors that really determines the quality of shrimp seeds is the quality and quantity of feed. This study aims to determine the appropriate dose ratio of natural feed and artificial feed for the growth of tiger prawns in the post larval stage. This research was conducted in September 2020. This study used a Completely Randomized Design (CRD) which consisted of 3 treatments 20 artemia/larvae, 25 artemia/larvae, 30 artemia/larvae. Each treatment was repeated three times. Parameters tested included absolute weight growth, absolute body length, feed efficiency, survival rate, and water quality. Data analysis used ANOVA to see the significance of the effect on the growth of absolute body weight, absolute body length, feed efficiency, survival rate and water quality were analyzed descriptively. The highest average absolute weight growth was obtained in treatment C (0.8 gram) then treatment B (0.65 gram) and the lowest was in treatment A (0.62 gram). The highest mean absolute body length was obtained in treatment C (6.6 mm), then B (5.4 mm) and the lowest was in treatment A (4.3 mm). The highest average value of feed efficiency was in treatment C (9.25%) followed by treatment B (7.56%) and the lowest in A (7.17%). The highest average survival value of tiger shrimp post larvae was obtained in treatment C (77%), followed by treatment B (67%) and the lowest in treatment A (19%). In general, the dose of artemia 30 heads/post larvae was the best treatment with an average weight (0.8 gram), body length (6.6 mm), feed efficiency (9.25%) and survival rate (77%).Keywords: artemia, survival rate, growth, tiger shrimp
