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

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.

Abstract

Vannamei shrimp (Litopenaeus vannamei) are one of the mainstays of Indonesia's aquaculture sector, which has great export potential. The development of Millennium Shrimp Farming (MSF) or millennial generation of shrimp farming means that the younger generation is encouraged to actively farm shrimp in a millennial way with the concept of cultivation using small amounts of land, low salinity and maximizing the regulation of water quality. Water quality in vannamei shrimp cultivation is managed by utilizing the application of probiotics and plankton growth. Plankton plays an important role in aquaculture, as natural food and an indicator of the fertility and stability of water bodies. Plankton itself is one of the main components in the food chain system and food web in vannamei shrimp cultivation. The aim of this research was to determine the type of plankton found in the vannamei shrimp ponds of Pangandaran Marine and Fisheries Polytechnic Teaching Factory. The data analysis method used is descriptive quantitative. The test parameters in this research were: plankton abundance, plankton diversity, plankton uniformity and dominance of plankton species found in vannamei shrimp ponds. The results of plankton identification in vannamei shrimp cultivation ponds in Pangandaran Maritime and Fisheries Polytechnic Teaching Factory revealed 7 species of plankton, including: (50-71)% from the Chlorophyta (green algae) group; (16-32)% from the Cyanophyta group (blue-green algae); (2-13)% from the Chrysophyta group (diatoms); 1% from the Phyrrophyta group (dinoflagellates); (2-3)% from the group of protozoa; (1-2)% from the Branchiopoda group and (2-8)% from the Euglenophyta group. The observation results show that the water in vannamei shrimp ponds has moderate biota community stability with plankton uniformity index values ​​under moderate or unstable conditions. Otherwise, there is no individual dominance in the shrimp pond waters.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the leading commodities. Environmental factors are crucial to intensive vannamei shrimp production. Changes in the plankton's composition can show the ecosystem's balance. This research was carried out from March to June 2022 in intensive ponds in the Gending district, Probolinggo Regency, East Java. Sampling was carried out over seven weeks. The population was calculated using a haemocytometer. The species diversity was calculated using the Shannon-Wiener formula, and the uniformity index was calculated using the Odum formula. The abundance of zooplankton did not have a significant relationship with water quality parameters because each species was affected by different water quality parameters. The N/P ratio value does not directly impact the plankton population in this shrimp pond, where the results obtained from the pond waters have low diversity, which means that the waters have a low level of uniformity. There is no dominance of certain species
