Abstract

This study aims to analyse the socio-economic conditions of the fishing community in Bianci Village, Raja Ampat Regency, Southwest Papua Province. A descriptive quantitative method was used, with data collected through observation, interviews, and questionnaires involving 10% of the total households. The results show that most fishermen have only completed elementary education (64%), are in their productive age, and support relatively large families. Public facilities, consisting of one elementary school, one mosque, and a single posyandu (integrated health post) with restricted service frequency, are limited. Fishing operations utilise simple wooden boats with outboard engines and traditional nylon hand lines, producing an average catch of 10–15 kg per trip, predominantly groupers. The average monthly income of fishermen reaches IDR 6,018,000, exceeding the regional minimum wage of Southwest Papua, indicating a relatively prosperous economic condition. Despite limited infrastructure, the economic potential of the fishing community remains promising and should be supported through integrated coastal empowerment programs.

Abstract

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

Abstract

Perairan Untia merupakan salah satu kawasan pesisir di Makassar yang memiliki aktivitas perikanan dan ekonomi yang tinggi. Perubahan pola curah hujan dapat memengaruhi aktivitas perikanan, kualitas air, dan ekosistem lokal. Variasi suhu permukaan laut (SPL) yang disebabkan oleh faktor seperti musim Timur dan musim Barat dapat memengaruhi distribusi dan intensitas curah hujan. Penelitian ini menganalisis data SPL dan intensitas curah hujan selama lima tahun terakhir (2019–2024) di Perairan Untia, Makassar. Data diperoleh dari Stasiun Meteorologi Maritim Makassar. Analisis dilakukan menggunakan uji normalitas, uji korelasi Pearson, dan analisis korelasi silang (cross-correlation) untuk mengetahui keterlambatan waktu (time lag) antara perubahan suhu laut dan terjadinya curah hujan. Hasil uji korelasi menunjukkan SPL memiliki hubungan yang lemah dengan curah hujan di Musim Barat (r = -0.31) dan Musim Peralihan I (r = -0.05), serta hubungan kuat hingga sangat kuat di Musim Timur (r = 0.53) dan Musim Peralihan II (r = 0.77). Hasil analisis cross-correlation memperlihatkan adanya time lag sekitar 1 bulan antara peningkatan SPL dan terjadinya hujan, terutama pada Musim Timur dan Peralihan II. Temuan ini penting untuk mendukung prediksi iklim lokal dan manajemen sumber daya pesisir.
