Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak bawang putih (Allium sativum) yang tepat terhadap penetasan telur ikan bandeng (Chanos chanos). Penelitian ini dilakukan di Balai Budidaya Perikanan Air Payau (BBPAP) Ujung Batee pada bulan Juli hingga Agustus 2014. Desain eksperimen yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 6 taraf perlakuan dan 3 ulangan. Sampel yang digunakan adalah telur ikan bandeng (Chanos chanos) yang telah terbuahi sebanyak 100 butir per wadah/ulangan. Perlakuan yang dilakukan meliputi perlakuan konsentrasi ekstrak bawang putih (Allium sativum) ; 0 (kontrol) ; 500 ; 1.000 ; 1.500; 2.000; 2.500 ppm. Hasil uji ANOVA menunjukkan bahwa penambahan ekstrak bawang putih berpengaruh sangat nyata terhadap daya tetas telur ikan bandeng pada taraf uji 1%. Uji lanjut BNJ menunjukkan bahwa perlakuan konsentrasi ekstrak bawang putih terbaik adalah pada konsentrasi 2.000 ppm.Kata kunci: Ikan bandeng (Chanos chanos), Daya tetas telur, Ekstrak bawang putih (Allium sativum).

Danau Laut Tawar terletak di Kabupaten Aceh Tengah Provinsi Aceh. Danau Laut Tawar telah banyak dimanfaatkan sebagai lokasi penangkapan, budidaya keramba jaring apung dan tempat parawisata yang menyebabkan terjadinya degradasi sumberdaya dan penurunan kualitas perairan. Perubahan kualitas perairan sangat mempengaruhi keanekaragaman organisme didalamnya, salah satu organisme yang berdampak adalah makrozoobentos. Penelitian ini bertujuan untuk mengetahui struktur komunitas makrozoobentos di Danau Laut Tawar. Penelitian ini dilakukan pada bulan Januari-April 2022. Penelitian ini menggunakan metode Purposive Sampling dengan3 kali pengulanganpada 5 stasiun yaitu Desa Mandale, dan Desa One-one yang mewakili perairan keramba jaring apung. Desa Mepar, Desa Mandale, Desa Kalasegi yang merupakan perairan non keramba jaring apung. Hasil penelitian yang telah dilakukan, diperoleh 6 kelas, 14 famili, dan 844 individu makrozoobentos. Spesies yang paling mendominasi adalah Melanoides tuberculata dari kelasGastropoda. Kelimpahan makrozoobentos Danau Laut Tawar pada stasiun keramba jaring apung sebesar 2.963-3.438 individu/m² dan stasiun non keramba jaring apung sebesar 440-1.563 individu/m². Nilai keanekaragaman yang diperoleh berkisar 2,14-3,07 yang tergolong sedang sampai tinggi. Indeks keseragaman yang diperoleh pada perairan keramba jaring apung dan non keramba jaring apung berkisar antara 0,01-0,99 yang masih tergolong stabil. Indeks kesamaan jenis disemua stasiun termasuk dalam kategori tinggi. Tipe substrat dasar yang paling mendominasi adalah substrat lumpur berpasir. Kualitas perairan masih dalam kondisi stabil yang mendukung kehidupan makrozoobentos. Berdasarkan analisis PCA diperoleh keterkaitan makrozoobentos dengan beberapa parameter kualitas air sebesar 78,9%.

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Abstract. The aims of the present study was to evaluate community structure and biomass of phytoplankton based on the depth stratification in the waters of Lake Laut Tawar. Sampling was conducted during March and April 2010. The results showed that 43 species of phytoplankton belonging to five classes were found in Lake Laut tawar. The most common class was Chlorophyceae with 20 genera, followed by Bacillariophyceae (diatoms) by 9 genera, Cyanophyceae (10 genera), Dinophyceae (2 genera), and Euglenophyceae (2 genera). The highest species composition was found at II with 15 m depth (24 genera), while the highest abundance of phytoplankton was occured at station with 10 depth (155600 cells/l), while the lowest abundance was obtained at 15 depth (12745 cells/l). Overall the phytoplankton population in Lake Laut Tawar was dominated by Bacillarophyceae. In addition, the diversity index of phytoplankton was in moderate level (2.34), while the evenness index was ranged from 0.43 to 0.87, indicate the distribution of the individuals of each species was varied, however there was no predominant species detected.Keywords.

This study aimed to determine the optimal concentration of Moringa oleifera leaf extract as an antibacterial agent on Litopenaeus vannamei larvae that are infected by Vibrio sp.. It was conducted in 15 March - 15 April 2019 at PT. Global Gain Superior Seeds, Pantai Cermin, North Sumatera. The research used a completely randomized design (CRD) method with five treatments and four replications. The shrimps infected by Vibrio sp. were immersed into M. oleifera leaf extract in various concentration of (A) 0 ppm, (B) 400 ppm, (C) 600 ppm, (D) 800 ppm, and (E) 1000 ppm for ±15 minutes. The size of shrimp used was post-larvae 8 (length of 3.5-5 mm/ind). The best performance results of vannamei shrimps were obtained in treatment E (1000 ppm), namely length growth of 16.75 ± 1.16 cm, weight growth of 0.92 ± 0.89 g and survival rate of 91±7.87%.Keywords:Moringa oleiferaVibrio sp.Immersion

Studi makanan dan kebiasaan makan sangat berpengaruh terhadap pertumbuhan suatu organisme karena dalam budidaya pakan memegang peranan yang sangat penting. Tujuan pada penelitian ini adalah menganalisis kebiasaan makan lobster air tawar (Cerax quadricarinatus) di Danau Laut Tawar, Kabupaten Aceh Tengah. Metode yang digunakan dalam penelitian ini yaitu pengambilan sampel secara acak sederhana dengan 3 titik stasiun dan menggunakan sebanyak 35 sampel, kemudian diawetkan dengan formalin 4%. Analisis kebisaan makan lobster dilakukan di Laboratorium Kesehatan Ikan dan Lingkungan, BBI Lukup Badak, Dinas Perikanan Kabupaten Aceh Tengah. Berdasarkan hasil penelitian kebiasaan makan pada lobster ditemukan komposisi makanan yang terdiri dari hewan (Cacing dan Oithona), tumbuhan, dan 20 genus fitoplankton dari 9 kelas (Chlorophyceae, Zygnematophyceae, Cyanophyceae, Charophyceae, Ulvophyceae, Bacillariophyceae, Macroconidia, Pteridopsida, dan Deutromycetes). Berdasarkan nilai Index of Preponderance (IP) makanan utama lobster air tawar adalah detritus baik untuk semua stasiun.
