Abstract

Coastal areas of Banyuwangi Residence are location that exposed to industrial and settlement activity. This condition makes much waste contaminated coastal area of Banyuwangi Residence, and can decrease quality of the area. Plankton is organism that live depended on quality of aquatic environment. Several species of plankton can live on contaminated water. So we can use diversity of plankton as water pollution indicator. The aim of this research is to know coastal contamination status in Banyuwangi Residence. Plankton was used as bioindicator to anticipating coastal pollution. This research is conducted at the dry season on 2010. The result of this research showing the value of shannon diversity index are : 0.60796, 1.17653, 2.25307, 0.54356. This value showing water pollution happened in coastal area of Banyuwangi Residence. The level of water pollution that happened is middle level until heavy level.  Keywords  : Banyuwangi, plankton, bio-indicator, pollution. Diversity indeks

Abstract

Saat ini awal dan akhir periode budidaya rumput laut sudah tidak dapat dipastikan lagi karena mengalami pergeseran yang diduga akibat perubahan iklim global.  Hal tersebut mengakibatkan gagal panen dan rendahnya rendemen karaginan.  Salah satu cara untuk mengetahui dampak perubahan iklim terhadap budidaya rumput laut (Kappaphycus alvarezii) adalah dengan mengkaji parameter kualitas air yang mempengaruhi pertumbuhannya yaitu suhu.  Melalui penelitian ini diharapkan diperoleh temuan baru mengenai pengaruh suhu terhadap pertumbuhan rumput laut.  Hasil penelitian menunjukkan bahwa, Kappaphycus alvarezii yang diberi perlakuan suhu 200C, 250C, 300C, 350C dan 400C tidak menunjukkan perbedaan yang nyata terhadap rata-rata pertumbuhan hariannya. Kata kunci: suhu, pertumbuhan, Kappaphycus alvarezii

Abstract

Perairan Indonesia merupakan daerah ruaya (migration)dari jenis-jenis mamalia laut (marine mammals) seperti paus, lumba-lumba dan ikan duyung, terutama di wilayah Indonesia bagian timur.Cetacea dan berbagai jenis biota laut peruaya lainnya termasuk jenis penyu hingga saat ini keberadaannya semakin terancam.Pemerintah Indonesia, melalui Departemen Kelautan dan Perikanan melakukan upaya perlindungan spesies bagi mamalia laut dengan membentuk dan menetapkan kawasan konservasi Laut Sawu sebagai Kawasan Konservasi Perairan Nasional (KKNP).Penetapan suatu kawasan menjadi kawasan yang dilindungi tidak lepas dari kendala dan hambatan yang dihadapinya, tetapi hambatan dan kendala ini dapat dijadikan suatu tantangan dalam mengelola sumberdaya alam yang lebih efektif.Pengelolaan yang efektif bagi mamalia laut yakni dengan tetap melindungi ekosistem dan habitatnya, melakukan penelitian dan monitoring, pemantauan terhadap illegal fishing maupun destructive fishing.Kata Kunci :Cetacea, Konservasi, Tantangan, Pengelolaan efektif

Abstract

Indonesian short fin eel (Anguilla bicolor) was one of Indonesian fishery commodities which have high value not only in local market but also western market. Advantages of Indonesian short fin eel not only their high value because of prospectively in international market, but also the quality of  Indonesian short fin eel itself that contain high vitamin and micronutrient. Weaknesses of Indonesian short fin eel was their growth classified slow. That was can be overcome by giving the exact feed. The purpose of this research was to know the effect of combination between artificial feed and natural feed with different percentage to protein retention, fat retention and energy retention of Indonesian short fin eel (Anguilla bicolor). This research used experimental method and Completely Random Design method with five treatments. Each treatment was replicated four times. The treatment used were : 100% of artificial feed (A), 75% of artificial feed and 25% of natural feed (B), 50% of artificial feed and 50% of natural feed (C), 25% of artificial feed and 75% natural feed (D), and 100% natural feed (E). The main parameters measured were protein, fat, and energy retentions. The supporting parameters observed was growth rate and water quality. Data analysis used analysis of variance (ANOVA) to know the effect of the treatments. The  difference among treatments were known by using Duncan’s Multiple Range Test (DMRT).The result showed that combination between artificial  and natural feeds with difference percentage showed different effect (p0,05) to fat retention of Indonesian short fin eel therefore they didn’t showed different effect to protein and energy retentions of Indonesian short fin eel (p0,05). Water quality of Indonesian short fin eel rearing medium was 28-31oC in temperatures, 7-8,5 in pH, 3,5-5,8 mg/l in dissolved oxygen and 0,003 mg/l in ammonia. Keywords : Anguilla bicolor, artificial feed, Tubifex tubifex, protein retention, fat retention, energy retention.

Abstract

Indonesia has a marine biological resources are very large with the content of various types of creatures living in it. The biological richness of which are fish that have a benefit in the field of food and health. Tunafish (Euthynnus affinis) is a species that is very interesting to study both in terms of nutritional composition and in terms of its economy. The purpose of this study was to determine the nutrient content and chemical compounds contained in red meat and white meat tuna. Research methodology includes observation of morphology, proximate analysis and phytochemical analysis of tuna. The highest yield was found in meat that  50%. Proximate protein content of the highest in the white meat that was 68.36%, the highest fat in red meat was 5.6%, the highest in red meat ash 3.29%, and the highest water on the white meat that was 12.16%. In the white meat and red meat tuna contained alkaloid, steroid, and carbohydrate compounds (molisch). Keywords: proximate, chemical compounds, tuna (Euthynnus affinis)

Abstract

Cost for feed is about to 60-70% of fishery production costs, but the current feed price is higher as well, so need feed manipulation such as fermentation and feed ingredients substitution that are usually derived from wastes such as kepok banana peels. Fermentation with Trichoderma viride used 4 treatments and 5 replications for 7 days. Inoculum doses were P0 (0%), P1 (3%), P2 (5%) and P3 (5%). Result of this study showed statistically differences (p0.05) for crude protein contents and the best treatment was P2 (5%) and not statistically differences (p0.05) for crude fibre contents. Fermented banana peels with 5% inoculum dose could be used for feed ingredients substitution as isoenergy to replaced rice flour, corn flour and starch in feed formulation for common carp fish (Cyprinus carpio) that includes as likeable cultured fish and one of omnivore fish that tolerable for high amount artificial feed. Keywords: Waste. Kepok banana peels. Trichoderma viride. Substitution. Feed formula for common carp fish.

Abstract

Kawasan ekosistem mangrove Wonorejo Surabaya adalah salah satu kawasan hutan yang masih terjaga secara alami. Selain beranekaragam jenis mangrove, di wilayah hutan ini dapat pula dijumpai spesies-spesies biota laut dan pesisir lainnya, baik reptil, amphibi maupun aves (burung). Oleh sebab itu, kawasan ini sangat berpotensi untuk dapat dikembangkan sebagai daerah tujuan wisata alternative di Kota Surabaya. Agar menjadi ”ikon” kelestarian lingkungan pesisir di Surabaya, direkomendasikan bahwa lokasi ini sesuai untuk dijadikan sarana Eco-Tourism dan Edu-Tourism. Pengembangan 2 jenis wisata alternatif akan memiliki nilai tambah baik untuk peningkatan potesi ekonomi lokal masyarakat pesisir maupun untuk sarana pendidikan untuk mengenalkan keragaman ekosistem dan biota wilayah pesisir dan lautan.Untuk mencapai tujuan tersebut, perlu adanya dukungan dari pemerintah Kota Surabaya untuk mempersiapkan fasilitas, meyediakan sarana dan prasarana, memberdayakan masyarakat sekitar serta yang tak kalah pentingnya adalah mempromosikan wilayah tersebut sebagai daerah tujuan wisata alternatif. Kata Kunci : Wonorejo Surabaya, mangrove, eco-tourism, edu-tourism
