Abstract

This research is intended to analyze how macroeconomic factors influence the level of fisheries investment in Bandung city. Economic factors analyzed in this study include inflation, interest rates, and Gross Domestic Regional Product (GDRP) in Bandung city in the period 2010-2017. The method used throughout this research is the Literature Survey method by using multiple linear regression analysis methods. The results of multiple linear regression tests through the F-test and T-test to prove to be no significant positive relationship between inflation and the level of fisheries investment in Bandung city. The results of the multiple regression test also showed an insignificant negative relationship between the interest rate and the level of investment in the fisheries sector in Bandung city. GDRP has a significant positive relationship with the level of fisheries investment in Bandung city. R Square Test (R2) shows a value of 0.913 which means that 91.3% of the proportion of investment in the fisheries sector from 2010-2017 can be attributed to the variable inflation, interest rates, and GDRP. While 8.7% is due to other variables outside the tested model. Keywords: Fisheries Investment, Macroeconomics, Inflation, Interest Rates, Gross Regional Domestic Product

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

This study aimed to determine the effectiveness of filters on the growth performances of catfish fry (Clarias gariepinus) in the aquaponic system. The study was conducted in the Ciparanje Green House, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor. A completely randomized design with four treatments and three replications was applied, namely treatment A: Water circulation using bioball filter medium, B: Water circulation using water spinach filter medium, C: Water circulation using bioball and water spinach filter media, and D: Water circulation using sponge filter medium (control). The container used for the maintenance was a fiber tank at 70 cm × 70 cm × 70 cm size filled with 257 L water and a stocking density of 15 fish/fiber. The parameters observed were survival rate, growth, feed conversion, and water quality. The results showed that the use of biological filter using water spinach produced the best growth performance of catfish. The best survival rate was also obtained by using water spinach filter (100%) with the absolute growth of 98.32 ± 15.6 g. The water quality an aquaponic system with water spinach filter supported the growth performance of catfish fry. Keywords: absolute growth, aquaponic, Clarias gariepinus, filters.

Abstract

Sampah plastik banyak dijumpai di berbagai wilayah pesisir, terbawa oleh gelombang arus dan pasang surut, serta kontribusi aktivitas daratan melalui sungai yang bermuara di laut. Ekosistem pesisir yang saat ini mengalami dampak peningkatan sampah plastik antara lain terumbu karang, padang lamun, pantai dan ekosistem mangrove. Ekosistem mangrove menjadi wilayah dengan ancaman akumulasi sampah makroplastik dengan jumlah sangat banyak dari berbagai aktivitas. Kawasan mangrove Karangsong di Kabupaten Indramayu merupakan ekosistem mangrove yang memiliki fungsi dan dikelola sebagai kawasan ekowisata. Riset ini bertujuan untuk mengetahui komposisi jenis dan kepadatan makroplastik di kawasan ekowisata Mangrove Karangsong. Penelitian menggunakan metode survei dengan plot transek 10 x 10 m2 secara stratified random sampling. Hasil penelitian ini menunjukkan makroplastik terbanyak merupakan jenis Polyethylene Terephthalate (PETE) sebesar 33,47% dengan kepadatan 5,43 potong/m2, sementara makroplastik paling sedikit dijumpai pada jenis Polyvinyl Chloride (PVC) sebesar 0,15% dengan kepadatan 0,01 potong/m2. Sebaran sampah makroplastik yang ditemukan umumnya terkumpul tersangkut pada sistem perakaran mangrove dan tertutup substrat sedimen. Jenis makroplastik yang ditemukan, mengindikasikan pentingnya pengelolaan sampah di kawasan ekowisata maupun dari sumber utama penghasil.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung rumput laut Eucheuma cottonii terhadap karakteristik kimia dan organoleptik cendol. Penelitian ini dilaksanakan di Laboratorium Pengolahan Hasil Perikanan, Fakultas Perikanan dan Ilmu Kelautan Universitas Padjadjaran, serta di Laboratorium (SIG) PT. Saraswanti Indo Genetech Bogor. Metode riset yang digunakan adalah metode eksperimen dengan menggunakan 4 perlakuan penambahan tepung rumput laut sebanyak 0%, 5%, 10%, dan 15% pada cendol. Uji organoleptik dilakukan sebanyak 25 orang panelis semi terlatih sebagai ulangan. Parameter yang diuji meliputi tingkat kesukaan kenampakan, aroma, rasa, dan tekstur serta kadar air, protein, lemak, abu, serat pangan. Data hasil uji organoleptik dianalisis dengan uji Friedman dan Bayes, sedangkan hasil uji kimia dianalisis secara deskriptif komparatif. Hasil riset ini menunjukkan bahwa penambahan tepung rumput laut Eucheuma cottonii pada cendol sebesar 5% merupakan perlakukan yang paling disukai berdasarkan parameter organoleptik dengan nilai rata-rata tingkat kesukaan kenampakan (7,3); aroma (6,8); rasa (7,0); dan tekstur (6,8) dan menghasilkan komposisi proksimat yaitu kadar air (91,55%); kadar abu (0,16%); kadar protein (0,59%); kadar lemak (0,02%); karbohidrat (7,70%) dan kadar serat pangan menjadi (1,94%).
