Abstract

Information on macroalgae species and their distribution in the coastal areas of Kolaka Regency is extremely limited. This research is a preliminary study of macroalgae species found along the coast of Kolaka Regency, conducted in the waters of Tanggetada Village. The research applied the belt transect method and 1 x 1 m quadrats using a 50 m long line transect with a placement interval of each quadrat of 5 m, which was repeated 3 times with a distance of 50 m between line transects. The results showed that 20 species of macroalgae, namely Caulerpa verticillata, Caulerpa racemosa, Dyctiosphaeria versluysii, Dyctiosphaeria cavernosa, Udotea sp., Halimeda opuntia, Halimeda macroloba, Halimeda sp., Boodlea composita, Gelidiella acerosa, Hormophysa triquetra, Sargassum sp., Lobophora variegata, Padina minor, Liagora sp., Avrainvillea obscura, Gracillaria coronopifolia, Valonia aegagropila, Acanthophora spicifera, and Dictyota dichotoma, come from 3 group, namely 11 species from the Chlorophyta, 5 species from the Rhodophyta, and 4 species from the Phaeophyta. Water conditions in Tanggetada village still support macroalgae growth. Further research with a wider scale is needed in the observation area to reach the coral reef area and an overview of the ecological index of macroalgae in the Tanggetada village. Keywords: Macroalgae Divisi; Macroalgae Species; Tanggetada; Water conditions Abstrak Informasi yang tersedia mengenai spesies makroalga dan distribusinya di wilayah pesisir Kabupaten Kolaka masih sangat terbatas. Penelitian ini merupakan studi pendahuluan mengenai spesies makroalga yang ditemukan di sepanjang pesisir Kabupaten Kolaka, yang dilakukan di perairan Desa Tanggetada. Penelitian dilaksanakan menggunakan metode belt transect dan kuadrat 1 x 1 m menggunakan transek garis sepanjang 50 m dengan interval penempatan setiap kuadrat sebesar 5 m yang diulangi sebanyak 3 kali ulangan dengan jarak antar transek garis sebesar 50 m. Hasil penelitian menemukan 20 jenis makroalga yaitu Caulerpa verticillata, Caulerpa racemosa, Dyctiosphaeria versluysii, Dyctiosphaeria cavernosa, Udotea sp., Halimeda opuntia, Halimeda macroloba, Halimeda sp., Boodlea composita, Gelidiella acerosa, Hormophysa triquetra, Sargassum sp., Lobophora variegata, Padina minor, Liagora sp., Avrainvillea obscura, Gracillaria coronopifolia, Valonia aegagropila, Acanthophora spicifera dan Dictyota dichotoma yang berasal dari dari 3 kelompok yakni 11 jenis dari Chlorophyta, 5 jenis dari Rhodophyta dan 4 jenis dari Phaeophyta. Nilai rata-rata kondisi perairan Desa Tanggetada masih termasuk dalam kisaran nilai optimum untuk mendukung pertumbuhan makroalga. Namun demikian, penelitian ini masih membutuhkan penelitian lanjutan dengan skala area pengamatan yang lebih luas hingga mencapai daerah terumbu karang untuk menggambarkan indeks ekologi makroalga yang berada di Pesisir Tanggetada.

Abstract

Perikanan tangkap merupakan sektor perikanan penting dalam meningkatkan perekonomian khususnya nelayan. Namun sektor ini masih menghadapi banyak tantangan dan permasalahan. Nelayan Desa Tondowolio memiliki produktivitas perikanan tangkap yang masih tergolong rendah yang disebabkan oleh rendahnya infrastruktur dan teknologi. Sehingga membutuhkan solusi dalam menyelesaikan permasalahan melalui hilirisasi teknologi salah satunya alat pengumpul ikan berupa rumpon dasar. Tujuan pelatihan pembuatan rumpon dasar adalah untuk meningkatkan keterampilan nelayan dalam membuat alat bantu pengumpul ikan untuk meningkatkan hasil tangkapan. Metode pelaksanaan kegiatan yaitu sosialisasi fungsi dan keunggulan rumpon dasar, persiapan alat dan bahan, demonstrasi serta pendampingan pembuatan rumpon dasar. Pelatihan pembuatan rumpon dasar dilaksanakan di Desa Tondowolio dengan Mitra sasaran Kelompok Nelayan Dayung Sakti Tondowolio. Hasil pelatihan diperoleh bahwa nelayan mitra mampu mengetahui dan melakukan seluruh tahapan pembuatan rumpon dasar meliputi persiapan alat dan bahan, serta pembuatan rumpon dasar dengan mengikuti langkah-langkah yang diperoleh dari hasil sosialisasi.

Abstract

This study aims to analyze the influence of consumers' purchasing power on the demand for Malaja fish in Tanggetada District, Kolaka Regency. The research employs a quantitative descriptive method with simple linear regression analysis. Data were collected through questionnaires distributed to 100 respondents who are consumers of Malaja fish. The independent variable is purchasing power, measured by income, while the dependent variable is demand, measured by purchase frequency and quantity. The results show a significant influence of purchasing power on demand, with a p-value of 0.012 (< 0.05). The coefficient of determination (R²) is 0.48, indicating that 48% of the variation in demand is explained by purchasing power. These findings highlight the important role of purchasing power, although other influencing factors remain unexamined

Abstract

Bone Regency is one of the coastal areas in South Sulawesi with abundant fisheries resources, both in marine and freshwater environments. This study aims to analyze fish species diversity, catch potential, and environmental factors influencing fisheries sustainability in the waters of Bone Regency. Data were collected through field surveys, fisher interviews, and environmental parameter measurements such as temperature, salinity, and water pH. The research was conducted from March to May 2025 at several water sites, including the coastal area of Bone Bay, the Walanae River, and several community aquaculture ponds. The results showed that more than 25 dominant fish species were caught by fishers, with major contributions from small pelagic fish (sardinella, anchovy), demersal fish (grouper, snapper), and freshwater species (tilapia, milkfish). Data analysis revealed a moderate to high species diversity, with Shannon-Wiener index (H’) values ranging from 2.5 to 3.2. Environmental factors played an important role in determining fish availability, particularly during the transitional season. Fishers’ catches showed a declining trend compared to the past five years, presumably due to overfishing pressure and habitat degradation. These findings highlight the need for ecosystem-based fisheries management and the adoption of environmentally friendly fishing gear. Education and fisher assistance programs are highly recommended to ensure the sustainability of fisheries resources in Bone Regency.
