Abstract

Karamba Jaring Apung (KJA) merupakan salah satu metode dalam kegiatan budidaya ikan di perairan umum seperti Waduk Cirata. Masalah yang umum dihadapi oleh pembudidaya ikan KJA di Waduk Cirata yaitu rendahnya konsentrasi oksigen di lokasi tersebut, sehingga akan berpengaruh secara langsung terhadap kehidupan ikan-ikan yang dibudidayakan. Rendahnya oksigen akan menyebabkan rendahnya laju pertumbuhan yang tentunya akan menurunkan produktivitas. Objek penelitian ini adalah produktivitas ikan bawal dan nila yang dibudidayaka secara polikultur dalam KJA di Waduk Cirata. Penelitian ini dilakukan selama 10 minggu dengan metode experimental yang menggunkanan 2 perlakuan yaitu KJA dengan airasi dan KJA tanpa aerasi. Adapun parameter yang diukur adalah oksigen terlarut (DO), amonia bebas (NH3), suhu, pH dan bobot ikan. Konsentrasi DO rata-rata pada KJA dengan aerasi lebih tinggi 8,26% dibandingkan KJA tanpa aerasi. Berdasarkan hasil analisis uji t, produktivitas KJA dengan menggunakan teknologi aerasi memberikan hasil produktivitas lebih baik bandingkan dengan tanpa menggunakan aerasi. Produktivitas rata-rata KJA dengan aerasi sebesar 11,47 Kg/m3, sedangkan KJA tanpa Aerasi adalah 8,91 Kg/m3.

Abstract

AbstractAquaponics is new aquaculture integrating the technology of fishes and plants due to less availability of land. This study aimed to determine the optimum retention period in the aquaponics farming of sangkuriang catfish (Clarias gariepinus) integrated with water spinach (Ipomoea reptan) to generate the water to support the catfish production. This study conducted in 40 days between May to June 2016 at Ciparanje Fish Hatchery Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The design of this study was completely randomized, with five treatments and three replications. The treatments retention periods were 5, 10, 15, 20 minutes, and control (no water flow). The study showed that the retention period affected water spinach’s inorganic nutrient absorption in sangkuriang catfish farm. The 15 minutes retention period gave the most desirable result, with a flow of 0.072 L/s that reduced 58.83% of nitrate, and 33.32% of ammonia has been produced by fish farming activities. The highest specific growth rate of the sangkuriang catfish obtained in 15 minute retention period of 4.01 % Keywords: aquaponics, sangkuriang catfish, water spinach, retention periods  AbstrakAkuaponik adalah teknologi akuakultur baru yang mengintegrasikan ikan dan tanaman karena ketersediaan lahan yang semakin rendah. Penelitian ini bertujuan untuk menentukan periode retensi optimum pada budidaya akuaponik ikan lele sangkuriang (Clarias gariepinus) yang terintegrasi dengan kangkung air (Ipomoea reptan) untuk menghasilkan air yang mendukung produksi lele. Penelitian ini dilakukan selama 40 hari di Laboratorium Budidaya  Ikan Ciparanje, Fakultas Perikanan dan Ilmu Kelautan, Universitas Padjadjaran. Penelitian ini menggunakan rancangan acak lengkap, dengan lima perlakuan dan tiga kali ulangan. Perlakuan berupa periode retensi 5, 10, 15, 20 menit, dan kontrol (tidak ada aliran air). Hasil penelitian menunjukkan bahwa periode retensi memengaruhi penyerapan nutrisi anorganik oleh bayam air dalam budidaya ikan lele sangkuriang. Periode retensi 15 menit memberikan hasil yang paling baik,  dengan aliran 0,072 L/s mengurangi 58,83% nitrat, dan 33,32% amonia dalam media budidaya ikan. Laju pertumbuhan spesifik ikan lele sangkuriangtertinggi diperoleh pada perlakuan waktu retensi 15 menit, yaitu sebesar 4,01%.  Kata kunci: akuaponik, ikan lele sangkuriang, kangkung darat, waktu retensi

Abstract

Cijulang River is one of the leading ecotourism objects in Pangandaran, West Java Province, Indonesia. However, the river has a variety of activities that can increase the water pollution in the river such as Green Canyon cliffs tourism, ecotourism of mangrove conservation, housing, and industrial siting. Macrobenthos is one of the bio-indicators that can assess the rate of water pollution in rivers, especially their organic pollutants. Therefore, this research aims to determine water pollution status in Cijulang River Tourism by comparing various biotic indices. The study was conducted at four site sampling locations from upstream to downstream in the rainy season period and dry season period using different methods namely, line transect model, water quality assessment by biological indexing (diversity, species dominant, and family biotic), species deficit, and organic measurement. The research showed 5873 macrobenthos and divided into 27 species with an average abundance of 167 ind.m-2 and are mainly dominated by gastropod species Faunus ater (40%). They are extreme species that can live in high organic pollution and water salinity. This divided the research of quality water assessment of Cijulang River into three categories as follows: slightly polluted (score 36-46) at Green Canyon site, moderately polluted (score 50-60) at Boat Shelter and Muara Cijulang location, and highly polluted (score 66) at Nusawiru site.Keywords:RiverBio-indicatorOrganicAquatic pollution

Abstract

Chitosan is an ingredient that can be used as a feed additive. In aquaculture, chitosan can be used as an antimicrobial, antifungal, antioxidant growth-promoting and immunostimulant. This study aims to determine the optimum addition of chitosan to feed to increase growth and daily feed consumption of giant gourami. The method used in this research is an experimental method using a completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without chitosan (control), (B) 2.5 g/kg feed, (C) 5 g/kg feed, (D) 7.5 g/kg feed, and (E) giving chitosan of 10 g/kg feed. The test fish used were giant gourami with a 6 8 cm length and a weight of 8 10 g. The container used was hapa measuring 1 x 1 x 1 m3 with a density of 15 fish per treatment and 42 days of maintenance. The feeding rate was 3% of the fish biomass. Data from observations of length and weight were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level; if there was a significant difference, Duncan's multiple distance test was performed. The results showed that addition of chitosan 7.5 g/kg feed was effective in improving growth on giant gourami. During maintenance, absolute length growth was 2.90 0.10 cm, absolute weight growth was 15.33 1.19 g, daily growth was 36.51 2.84%, feed conversion ratio was 1.69 0.06, and survival rate was 100 0.00%. This research concluded that the optimum level of addition of chitosan to increase growth and daily feed consumption of giant gourami was 7.5 g/kg feed.Keywords:ChitosanFeed additiveGiant gouramiGrowth
