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

This study aimed to determine the effect of duckweed and fish meal on feed on the growth and survival of Nirvana tilapia (Oreochromis niloticus). The tested tilapia were 8-10 cm long and weighed 12 g, kept in 9 aquariums (120 cm x 50 cm x 40 cm), three aquariums as control, three aquariums for treatment A and three aquariums for treatment B, with each each treatment A. 5% dry duckweed and fish meal (1 kg commercial feed, 25 g dry duckweed and 25 g fish meal), treatment B. 5% wet duckweed and fish meal (1 kg commercial feed, 25 g wet duckweed and 25 g g of fish meal) and treatment K (control) without treatment. The results showed that dukweed and fish meal could be used as additional feed for fish. Of the three feeds that gave the best growth, treatment A 5% (dried duckweed and fish meal) had a specific growth rate of 1.7% with a daily growth rate (GR) of 0.32 grams, and an absolute length of 3.16. cm with a survival rate of 99%.

Abstract

Rhizopora merupakan jenis tanaman bakau yang dominan ditanam oleh masyarakat di kawasan pesisir Pangandaran. Bakau jenis ini dipilih karena pertumbuhannya yang baik pada substrat jenis lumpur yang banyak terdapat di muara-muara sungai yang ada di Pangandaran. Perbanyakan bibit jenis Rhizopora pun tergolong mudah. Namun demikian belum banyak masyarakat yang secara khusus mengembangkan pembibitan bakau jenis Rhizopora, sehingga terkadang bibitnya harus didatangkan dari derah lain. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan bibit mangrove yang ditanam pada polibag dengan media berupa pasir, tanah merah, lumpur dan serbuk kelapa/cocopeat. Rancangan Acak Lengkap digunakan sebagai metode percobaan dengan perlakuan berupa empat media tanam yang berbeda dengan 50 ulangan. Total bibit Rhizopora yang ditanam yaitu sebanyak 200 bibit. Hasil pengamatan selama 60 hari dianalisis menggunakan analisis ragam dan uji Beda Nyata Terkecil. Pertumbuhan bibit tanaman pada keempat media tanam berbeda secara nyata dengan pertumbuhan rata-rata yang lebih baik yaitu pada media tanah sebesar 5,64 cm dan media lumpur sebesar 5,55 cm. Pertumbuhan rata-rata bibit pada media pasir dan cocopeat  lebih lambat yaitu masing-masing sebesar 5,25 cm dan 5,19 cm.Rhizopora is the dominant type of mangrove planted at coastal area by the people of Pangandaran . This type of mangrove was chosen because of its good growth on mud-type substrates that are widely found in river estuaries in Pangandaran. Propagation of Rhizopora seeds is also relatively easy. However, not many people have specifically developed Rhizopora mangrove nurseries, resulting the seeds have to be imported from other areas. This study measures the growth response of mangrove seedlings planted in polybags with four different media namely beach sand, red soil, mangrove mud and cocopeat. Completely randomized design was used as the experimental method with four different growing media as the treatment with 50 replications. The total number of Rhizopora seeds planted was 200 seedlings. The results of observations for 60 days were analyzed using analysis of variance and the Least Significant Difference test. The growth of plant seeds on the four planting media was significantly different with a better average growth of 5.64 cm in soil media and 5.55 cm in mud media. The average growth of seedlings on sand and cocopeat media was slower, which was 5.25 cm and 5.19 cm, respectively.

Abstract

Produksi garam menggunakan tambak geomembran model tunnel marak dikembangkan di Indonesia. Selain hasil garam yang lebih bersih dibandingkan dengan tambak kolam tanah, produksi garam dengan metode ini bisa dilaksanakan sepanjang tahun karena tidak terkendala oleh hujan. Namun demikian, proses penguapan pada kolam tunnel lebih lambat dibandingkan kolam terbuka sehingga waktu tunggu panennya menjadi lebih lama. Penelitian ini bertujuan untuk meningkatkan kecepatan penguapan pada tambak garam model tunnel dengan penggunaan plastik penutup tunnel berwarna hitam untuk meningkatkan suhu dan pengarah angin untuk meningkatkan aliran angin dalam kolom tunnel. Penelitian dilakukan dengan Rancangan Acak Lengkap dengan 4 perlakuan berupa tunnel berpenutup plastik bening tanpa pengarah angin sebagai kontrol, tunnel berpenutup plastik hitam tanpa pengarah angin, tunnel berpenutup plastik bening dengan pengarah angin dan tunnel berpenutup plastik hitam dengan pengarah angin. Kolam tunnel berukuran 200 x 100 x 35 cm dan diisi dengan air laut setinggi 30 cm. Parameter yang diukur yaitu berupa suhu, kelembapan dan kecepatan angin pada kolom tunnel serta penurunan tinggi muka air harian selama 30 hari. Data dianalisis menggunakan Analisis Sidik Ragam dan Uji Beda Nyata Terkecil. Penggunaan plastik penutup berwarna hitam dan pengarah angin berpengaruh nyata terhadap peningkatan kecepatan penguapan dengan kecepatan tertinggi diperoleh pada tunnel berpenutup plastik hitam dan pengarah angin dengan kecepatan penguapan 0,98 cm/hari atau setara dengan 19,6 liter/hari.Salt production using geomembrane ponds tunnel model is widely developed in Indonesia. In addition to producing salt that is cleaner than land ponds, salt production with this method can be carried out throughout the year because it is not constrained by rain. However, the evaporation process in tunnel ponds is slower than open ponds, so the production time until the harvest is longer. This study aims to increase the speed of evaporation in the salt pond model tunnel by using black plastic tunnel cover to increase temperature and wind direction turner to increase wind flow in the tunnel column. The study was conducted in a completely randomized design with 4 treatments in the form of a clear plastic covered tunnel without wind direction as a control, a black plastic covered tunnel without wind direction turner, a clear plastic covered tunnel with wind direction turner and a black plastic covered tunnel with wind direction turner. The tunnel pool measures 200 x 100 x 35 cm and is filled with seawater as high as 30 cm. Parameters measured were temperature, humidity and wind speed in the tunnel column as well as the daily decrease in water level for 30 days. Data were analyzed using the Test of Variance and the Test of Least Significant Difference. The use of black plastic covers and wind direction turner has a significant effect on increasing the evaporation rate with the highest rate obtained in the tunnel covered with black plastic and wind direction turner with an evaporation rate of 0.98 cm/day or equivalent to 19.6 liters/day.
