Bagan perahu merupakan alat tangkap yang prinsip kerjanya memanfaatkan cahaya lampu untuk mengumpulkan gerombolan ikan baik yang bersifat fototaksis positif atau ikan yang ingin mencari makan di sekitar cahaya lampu dan pada umumnya lebih efektif digunakan untuk menangkap ikan-ikan pelagis seperti ikan Teri, ikan Tongkol, dan cumi. Tempat Pelelangan Ikan (TPI) Desa Lamurukung merupakan salah satu pusat aktivitas perikanan tangkap di Desa Lamurukung Kecamatan Lamuru Kabupaten Bone, dimana jenis alat tangkap di TPI Desa Lamurukung mayoritas menggunakan alat penangkap ikan bagan perahu. Penelitian ini bertujuan untuk menganalisi kelayakan usaha pada pengoprasian alat penangkap ikan bagan perahu dengan beberapa indikator yaitu Analisa Rugi/Laba, Payback Period (PP), Analisa Net Present Value (NPV), dan Analisa Revenue Cost Ratio (R/C Ratio). Hasil penelitian menunjukan bahwa nilai keuntungan per tahun sebesar Rp. 233.464.667, PP sebesar 1,56, NPV sebesar 53.722.736,4, dan R/C Ratio sebesar 1,95, sehingga usaha pengoprasian alat penangkapan ikan bagan perahu layak untuk dilanjutkan dan dikembangkan.

One of the ecosystems in tropical waters is the coral reef. Coral reefs serve multiple functions, both ecologically and economically. The marine waters in Wakatobi Regency boast diverse coral reefs, and this study aims to assess the coral reefs in one of its regions, specifically in the waters around Hoga Island, part of Wakatobi National Park. The research was conducted from March to May 2023, involving direct observations at the research site. The collected data were then analyzed and presented descriptively concerning the percentage of coral reefs in the study area. The percentage of coral cover in the growth forms (lifeform) of the Wakatobi National Park tourism zone, region II, revealed that, at the first station, coral cover was 46.33%, dominated by Coral Branching (CB) at 22.36%, and Biotic, primarily Soft Coral (SC), at 14.95%. At the second station, coral cover was 36.13%, with Coral Branching (CB) accounting for 11.53%, and Soft Coral (SC) at 25.33%. The third station exhibited a coral cover percentage of 60.37%.

Jakarta Bay is one of the important waters in Indonesia that plays a major role in economic activities, shipping, defense, and coastal tourism. Therefore, field observations and numerical modeling with Mike 21 are needed to determine the pattern of tidal current movement. Field observations of currents and tides were carried out for 15 days at the marina beach where the observation data will later be processed using the admiralty method to determine the harmonic component and tidal type and the observation data is used to validate the data from the MIKE 21 modeling simulation. The tidal validation results got an RMSE value of 0.13 with a correlation of 0.95 and the current validation results got an RMSE value of 0.05 with a correlation of 0.14.

Teluk Jakarta merupakan salah satu perairan penting di Indonesia yang berperan besar dalam aktivitas ekonomi, pelayaran, pertahanan dan wisata pantai. Aktivitas tersebut tentu tidak lepas dari pengaruh oseanografi fisik salah satunya yaitu pola pasang surut dan arus laut. Penelitian ini bertujuan untuk melakukan simulasi pemodelan arus pasang surut di perairan teluk Jakarta menggunakan perangkat lunak mike 21. Pemodelan ini diperlukan untuk memahami dinamika arus pasang surut yang berpengaruh terhadap aktivitas pesisir dan infrastruktur di teluk Jakarta. Data yang digunakan dalam penelitian ini yaitu data batimetri, data angin, dan data pasang surut. Hasil simulasi pemodelan mike 21 selama 1 bulan di area teluk Jakarta didapatkan bahwa kecepatan arus pasut maksimum 0.15 m/s dengan tipe pasang surut harian tunggal (diurnal). Data pengamatan digunakan untuk memvalidasi data hasil model mike 21, validasi dilakukan untuk mengetahui keakuratan data hasil pemodelan yang telah dilakukan. Hasil validasi pasut mendapatkan nilai RMSE 0.13 dan validasi arus mendapat nilai RMSE 0.05. dari hasil validasi yang telah dilakukan bisa di simpulkan bahwa pemodelan yang telah dilakukan sudah cukup bagus karena mendekati nilai tinggi air yang sebenarnya.

This study was conducted to determine the socio-economic conditions of the foreign fish processing community in Ambesia Village, Tomini District, Parigi Motong Regency. This study was conducted in January 2024 - March 2024. A salted fish processor works in salted fish processing and knows the concept of salted fish processing principles. Salted fish processing activities include designing and implementing fisheries and offering salted fish prices. This study aims to determine the socio-economic conditions of salted fish processors in Ambesia Village, as well as to determine the prospects and obstacles in developing the salted fish business. Data collection was carried out using observation and interview methods, as well as questionnaires. Determination of respondents was carried out by census, namely taking the entire population consisting of 30 people from the salted fish processing community in Ambesia Village, Tomini District, Parigi Moutong Regency. In general, the economic conditions in Ambesia Village are supported by several types of alternative livelihoods for the community, such as fishermen, carpenters, laborers, civil servants, domestic helpers, mechanics, small entrepreneurs, traveling traders, and others. Constraints in the salted fish processing business are influenced by the availability of raw materials, low quality, and low level of education of salted fish processors. The profit of salted fish processors is Rp 3,754,346/month from the types of salted anchovies, lolosi, and dolo-dolo.

Rewataya Village is situated on Tanakeke Island, within the Takalar Regency. Despite its significance, previous studies have not addressed the mapping of changes in mangrove land area within this locale. The present research aimed to fill this gap by assessing alterations in mangrove land area from 2013 to 2023, alongside examining density and canopy cover conditions. The method employed for mapping changes in land area entailed utilizing the unsupervised method with maximum likelihood classification. Additionally, the assessment of mangrove conditions involved employing plot line transects to determine species density and hemispherical photography methods to evaluate canopy cover. Notably, two types of mangroves, namely Rhizophora mucronata and Rhizophora apiculata, are prevalent in this village. The mangrove species density in Rewataya Village, Tanakeke Island, is categorized as good. In addition, the canopy cover in Rewataya Village falls within the classification of very dense according to mangrove damage criteria. However, there has been a notable reduction in the mangrove ecosystem area between 2013 and 2023, with a decrease of 42.28 hectares (from 367.13 hectares to 324.84 hectares).Keywords: MangroveLandsat 8Rewataya villageUnsupervised

Indonesia merupakan negara kepulauan dengan memiliki wilayah yang sebagian besar adalah wilayah pesisir dengan mempunyai potensi yang kaya akan keanekaragaman hayati juga sumberdaya alam pada daerah pesisir. Salah satu sumberdaya pesisir yang memberikan kontribusi yang tinggi dalam lingkungan pesisir, yakni ekosistem padang lamun. Desa Barugaia merupakan salah satu desa yang terletak di Kabupaten Kepulauan Selayar, Sulawesi Selatan, yang memiliki padang lamun yang tersebar hampir merata di wilayah perairannya. Sebagai wilayah pesisir yang masyarakatnya sebagian besar bergantung pada laut untuk sumber penghidupan, keberadaan ekosistem lamun di Desa Barugaia dapat memberikan manfaat berkelanjutan bagi ekonomi lokal, khususnya bagi sektor perikanan.Tujuan penelitian ini untuk menghitung sebaran dan luasan padang lamun di Desa Barugaiya Kepulauan Selayar. Dalam penelitian ini digunakan citra Sentinel 2A yang kemudian dilakukan proses koreksi atmosferik lalu diolah menggunakan ArcGis 10.8. Penentuan titik koordinat dilakukan menggunakan Google Earth Pro. Sentinel 2A membawa berbagai petak-resolusi tinggi imager multispektral dengan 13 band spectral. Hasil penelitian menunjukkan luas sebaran padang lamun pada Desa Barugaia adalah sebesar 37,36 ha. Dimana yang paling dominan di tumbuhi lamun adalah wilayah bagian sebelah selatan, dan yang kurang di dapati adalah wilayah bagian timur
