Abstract

Mangrove ecosystems in coastal areas play an important role in supporting physical, biological, and environmental economic functions. One of the alternatives to preserve the mangrove ecosystem is integrated area management. Bulaksetra Beach is a mangrove area located on the East Coast of Pangandaran which has the potential to be developed as an ecotourism area. The Edu-ecotourism area which combines conservation, education, research, and economy requires good and appropriate management. Analysis of land suitability, vegetation types and environmental conditions is important in making decisions and determining the feasibility of an area. Facilities and infrastructure are one of the elements and indicators that support the success of an Edu-ecotourism area. Observations on water conditions, types of mangrove vegetation, water substrate, weather and topography were carried out to determine the feasibility of developing facilities and infrastructure in the Bulaksetra area. The results showed that the Bulaksetra area was feasible to be developed into an Edu-ecotourism area with an average salinity measurement of 14 ppt, an average rainfall of 46.4 mm - 81.3 mm, a sandy mud substrate and a gentle topography. The zoning of the mangrove ecosystem was carried out based on the main mangrove vegetation in Bulaksetra, namely Avicennia alba and Rhizophora apiculata. The selection of vegetation in the landscape design is adjusted to the natural vegetation and topography in the Bulaksetra area. The supporting facilities for Bulaksetra Edu-ecotourism were designed include mangrove trekking, canoeing docks and mangrove galleries. Facilities are designed according to area size, landscape, and suitability of location. Further studies such as the selection of design and building materials, material costs, construction costs, operational costs and maintenance costs need to be carried out to determine the appropriate building construction. The development of Bulaksetra Edu-ecotourism facilities and infrastructure is expected to contribute to the development of the mangrove ecosystem so that it becomes a center for information, education, and conservation for the public, especially in Pangandaran Regency.

Abstract

Giant freshwater prawns, one of the freshwater aquaculture commodities which has high economic value and has wide market opportunity. Dissolved oxygen on giant freshwater prawn aquaculture is the one of necessary part on a prawn weight gain. Availability of dissolved oxygen can be increased by optimalization on mini wheel and blower use. Mini Wheel is a part of aquaculture technology application, especially on household scale aquaculture of giant freshwater prawn (M. rosenbergii). This assembly used recycle material which can still be used. This mini wheel was modified by 3 treatments, that A (blower without mini wheel pond treatment); B (one-propeller mini wheel pond treatment); C (two-propeller mini wheel pond treatment). This research used quantitative method and every treatment should has three repetitions. Aquaculture a household scale by applying mini wheel designed to find out its effect on water quality and growth of giant freshwater prawn (M. rosenbergii), with parameter ABW (Average Body Weight), ADG (Average Daily Growth), FCR (Feed Convertion Ratio) and SR (Survival Rate). This research showed that there is a significant difference between two-propeller mini wheel pond treatment, one-propeller mini wheel pond treatment and blower without mini wheel pond treatment. The optimum Dissolved Oxygen value on two-propeller mini wheel pond treatment was about 9 mg/L (morning and afternoon testing), Pond temperature on range 280C, and also pH has stability on 7. The best growth was found in two-propeller mini wheel pond treatment with Survival Rate (SR) 93%, Average Body Weight (ABW) 10 g/prawn, Average Daily Growth (ADG) 0.11 g/prawn, and Feed Convertion Ratio (FCR) 1.5.

Abstract

Pupuk tracemetal adalah larutan yang terdiri dari FeCl3.6H2O, EDTA, CuSO4.5H2O, CoCl2.6H2O, MnCl2.4H2O, Na2MoO4.H2O, ZnSO4.7H2O. Tujuan dari penelitian untuk mengetahui pengaruh perbedaan pemberian dosis pupuk pada peningkatan pertumbuhan dan kepadatan Tetraselmis sp. Pupuk NP adalah larutan yang terdiri dari NaNO3 dan DSP. Metode penelitian dilakukan menggunakan 4 perlakuan dengan 3 kali ulangan. Perlakuan yang diberikan yaitu perlakuan A pengurangan dosis pupuk NP 30% (7 ml) dan penambahan pupuk tracemetal 70% (17 ml), perlakuan B penambahan dosis pupuk NP (70%) (17 ml) dan pengurangan pupuk tracemetal 40% (7 ml), perlakuan C penambahan pupuk NP 60% (16 ml) dan pengurangan pupuk tracemetal 40% (6 ml), dan kontrol (K). Parameter yang diamati yaitu kepadatan sel harian, laju pertumbuhan harian, waktu generasi, dan kualitas air. Hasil penelitian menunjukan larutan penambahan dan pengurangan dosis pupuk berpengaruh terhadap pertumbuhan dan kepadatan Tetraselmis sp. dengan perlakuan B dengan dosis terbaik yaitu kepadatan sel sebesar 95 x 104 sel/mL dan laju pertumbuhan harian sebesar 3.99936 sel/mL/hari.

Abstract

Daun kelor (Moringa oleifera) merupakan bahan baku lokal yang memiliki kandungan protein nabati sebesar 21,49% sehingga dapat dijadikan alternatif dalam penyusunan formulasi pakan buatan. Potensi penggunaan daun kelor sebagai bahan baku dalam formulasi pakan dapat dilakukan dalam bentuk silase. Penelitian ini bertujuan mengetahui pengaruh penggunaan dan persentase silase daun kelor dalam formulasi pakan terhadap efisiensi nutrient dan pertumbuhan ikan nila (Oreochromis niloticus). Penelitian dilakasana dengan menggunakan metode Rancangan Acak Lengkap dengan 4 perlakuan dan 3 kali ulangan. Penelitian dilakukan dengan mengindetifiksi potensi silase daun kelor, persiapan pakan perlakuan dan uji biologi terkait efesiensi nutrient dan pertumbuhan ikan nila. Hasil penelitian menunjukan pemanfaatan silase daun kelor memiliki potensi yang sama seperti pakan komersial terhadap efisiensi nutrient dan pertumbuhan ikan nila. Nilai efisiensi nutrient tidak menunjukan perbedaan signifikan antara pakan formulasi silase dan tanpa silase daun terhadap rasio konversi pakan dan retensi energi (P>0.05), sebaliknya mengalami perbedaan signifikan terhadap rasio efisiensi protein (P<0.05). Pertumbuhan ikan nila yang diperoleh tidak menunjukan perbedaan signifikan antara formulasi silase dan tanpa formulasi terhadap pertumbuhan bobot mutlak, Laju Pertumbuhan Spesifik (LPS) dan tingkat kelangsungan hidup (P>0.05), hal ini menujukan bahwa kualitas pakan formulasi silase sama dengan pakan tanpa formulasi tapi memiliki tingkat rasio efisiensi protein yang rendah.
