The success of tiger shrimp farming in Oensuli Village's fishponds will be achieved if its location meets the criteria for tiger shrimp farming. Therefore it is important to conduct this research to find out the level of suitability of the actual land of tiger shrimp farms that are managed with high, and low production in Oensuli Village, Muna Regency. The method used is to compare the measurement results or the results of data analysis with the eligibility criteria/land quality for tiger shrimp farming. The results of this study illustrate the suitability of the actual land of tiger shrimp ponds with high and low production, as well as on land that has not been converted to ponds, it is obtained that the class category is quite appropriate (S2a1.2h), which means that there are water quality limiting factors such as temperature and brightness, and different tides ebbs are too high.

Abstract. Oetama D, Purnama MF. 2022. Freshwater gastropod community in South Konawe District, Southeast Sulawesi, Indonesia. Biodiversitas 23: 3364-3372. The freshwater gastropod population in South Konawe District, Southeast Sulawesi, Indonesia, consists of aquatic and terrestrial snail communities. This resource (gastropod) is an ecological and economic potential that needs to be maintained and utilized optimally and sustainably. This research was conducted in April-July 2021 and aimed to determine the ecological index of the inland gastropod community in the South Konawe District. The sampling location was determined qualitatively using the purposive sampling method and a simple random sampling technique (Quantitative based). Gastropod samples were collected manually (hand picking) with a paralon pipe (3.5 inches), Sieve (1 mm), and Gloves. The total gastropods obtained at 33 sampling locations in this district were 2635 individuals. The inland gastropods comprised 19 genera and 33 species spread over 9 families, namely Achantinidae, Ampullariidae, Ariophantidae, Lymnaeidae, Neritidae, Pachychilidae, Planorbidae, Thiaridae, and Viviparidae. The average abundance of gastropods reached 79.85 ind./m2 and the abundance of gastropod species ranged from 0.58-13.48 ind./m2. Overall, the analysis of gastropod ecology index showed a stable condition, where the diversity of gastropod species was categorized as high (H'= 3.03), moderate evenness (E= 0.87), and high species richness (R= 4.06). There were no dominant species (C= 0.08) and the gastropod distribution showed a clustered pattern (Ip= 0.02). These ecological index values indicated that the gastropod community in the inland waters of South Konawe District was in a stable condition. Although the gastropod community in the inland waters of the South Konawe District simultaneously has the same area as the invasive gastropod from the family Thiaridae, namely Melanoides tuberculata (O.F.Müller, 1774) and Tarebia granifera (Lamarck, 1816).

Motivasi penelitian ini adalah untuk menemukan metode transplantasi yang tepat bagi budidaya karang hias. Penelitian ini bertujuan untuk membandingkan tingkat pertumbuhan dan kelangsungan hidup fragmen karang yang ditransplantasi menggunakan metode ikat dan gantung. Penelitian ini dilaksanakan pada tahun 2017 sampai 2019 di perairan Labuan Beropa Kabupaten Konawe Selatan. Pada metode ikat fragmen karang diikat pada tonjolan rangka besi media transplantasi yang telah disiapkan, sedangkan pada metode gantung fragmen karang digantung pada rangka media transplantasi. Fragmen karang yang diuji pada Tahun pertama (F1) berasal dari koloni alami, tahun kedua (F2) dari koloni hasil transplantasi tahun pertama dan tahun ketiga (F3) dari koloni hasil transplantasi tahun kedua. Parameter yang diamati adalah tingkat pertumbuhan dan kelangsungan hidup. Hasil penelitian menunjukan bahwa Rata-rata pertambahan panjang fragmen karang yang ditransplantasi dengan metode ikat dalam 6 bulan adalah 51,9 mm hingga 58,9 mm, sedangkan pada metode gantung adalah 41,6 mm sampai 76,6 mm. Tingkat pertumbuhan fragmen karang F1 dan F2 lebih tinggi pada metode gantung sedangkan pada fragmen F3 pertumbuhan lebih tinggi pada metode ikat. Tingkat kelangsungan hidup fragmen karang menggunakan metode gantung berkisar 82,61% - 100%, sedangkan pada metode ikat berkisar 51,61- 82,93%.

Inti Sari Pembangunan pariwisata terintegrasi sektor andalan dan diversi�ikasi produk dan jasa merupakan salah satu arahan pembangunan daerah Kota Baubau. Salah satu model yang akan dikembangkan adalah kampung wisata berbasis produk unggulan mutiara. Tujuan penelitian adalah untuk mengkaji potensi kawasan dan perencanaan layout kampung wisata bahari berbasis produk unggulan mutiara di Kelurahan Palabusa. Metode pengumpulan data meliputi (1) survei terkait isu dan permasalahan pengembangan pariwisata berbasis pemanfaatan sumber daya perikanan, (2) Focus Group Discussion terfokus oleh beberapa multipihak terkait isu yang dikaji (3) veri�ikasi dan evaluasi hasil yang diperoleh di lapangan. Kondisi potensi sumber daya alam tersebut akan didokumentasikan. Metode analisa data mencakup analisis spasial, analisis pengembangan kawasan wisata dan tata letak (layout). Berdasarkan hasil analis spasial bahwa wilayah perairan laut yang masih dapat dikembangkan sebagai area budi daya kerang mutiara di Palabusa masih tersedia kurang lebih 61,23 hektar. Saat ini, area budi daya existing secara total baru mencapai 22,22 hektar yang terdiri atas 4,06 wilayah budi daya existing oleh masyarakat lokal dan sekitar 18,16 hektar wilayah budi daya milik PT. Selat Buton. Dari luas efektif tersebut, jika diasumsikan dimanfaatkan sebesar 25% saja, maka akan menampung jumlah keramba ukuran 6×12 meter sebanyak 138 unit. Hasil layout pengembangan kawasan mencakup ruang penerimaan, ruang pelayanan, ruang penyangga, ruang budi daya, ruang wisata/pelayanan, jalur sirkulasi, ruang konservasi situs sejarah. Model pengembangan kampung wisata di Palabusa mencakup ekonomi dan lingkungan, berbasis masyarakat dan keterlibatan multipihak.

Indonesia is one of the countries in the world that has many large islands and thousands of small islands. The small island is a unique environment with a distinctive community life. The main occupations of the people on small islands are generally fishermen and boat owners. This study aims to determine the socio-economic conditions of small islands, especially the livelihoods and incomes of local communities as well as the condition of coastal and shallow marine resources around small islands in supporting the development of marine tourism in one of the small islands in Indonesia. This research was conducted on Barrang Caddi islands, South Sulawesi Province, Indonesia. Data were collected through direct interviews, deep interviews and focus group discussions with local community, local government representatives, traditional leaders and community leaders. Marine resource data is carried out by direct observation and recording in the field. The data collected is analyzed descriptively. During our study, we are found that the main livelihood as fishermen, with an average level of income that is good for their daily life. Besides having a good income, the community also maintains their culture well. Some traditional cultural activities are well developed. This can be an activity that attracts visitors. The findings illustrate those economic conditions with good income are a strong driver in the development of tourist destination in this island. The strength of good tourism is to maintain all the supporting aspect such as cline white sand and marine resources. One of the marine resources that attracts the attention of visitors is coral reefs. Small island communities can increase their income by developing local potential management for marine tourism. Preserving marine resources is a strength that can be developed from marine tourism management. The recommendation of this research is that marine tourism is a prospective social economic development and marine resources strength of the small island.
