Abstract

Bagan Perahu (Lift Net) is a fishing business that requires a large investment value. The income of this business is uncertain because it relies heavily on catches and the fish season. The risk of uncertainty will affect business income and fishermen's income. This study aims to analyze the economic feasibility of fisheries and fishermen's businesses in Pelita Jaya Bay West Seram Regency, Maluku. The method used in this study is a survey. The results showed that the business carried out is still very profitable, seen from the business income earned by the owner, which is Rp68,548,000/year. Financial analysis shows the value of NPV over the next ten years amounting to Rp241,568,753; the value of IRR is still above the current bank interest rate of 42.98% and the net value of B/C>1, which is 2.58. The average monthly fishermen's income amounted to Rp1,288,311, and the existing income is still far below the UMR of Maluku Province. This is certainly not economically viable

Abstract

Penggunaan teknologi penginderaan jauh dalam bidang perikanan sangat bermanfaat bagi nelayan untuk memprediksi daerah potensial penangkapan ikan dengan menggunakan peta prediksi penangkapan. Umumnya nelayan tradisional banyak menggunakan pendugaan berdasarkan pengalaman melaut untuk mengetahui zona potensi penangkapan ikan. Penelitian ini bertujuan untuk memetakan kawasan potensial penangkapan ikan di perairan utara pulau Morotai menggunakan citra satelit Teraa Modis. Data yang digunakan adalah sebaran klorofil-a dan suhu permukaan laut pada musim timur dan peralihan 1. Metode yang digunakan adalah analisis overlay antara suhu permukaan laut dan konsentrasi klorofil-a untuk menentukan prediksi daerah potensial penangkapan. Hasil yang diperoleh suhu permukaan laut mempunyai sebaran antara (29-31oC) dimana konsentrasi suhu pada bulan Agustus lebih tinggi. Klorofil-a berkisar antara (0,1-0,25 mg/m3) dengan konsentrasi tertinggi pada bulan Maret. Hasil analisis antara hubungan suhu permukaan laut dan klorofil-a melalui regresi linear sederhana, terihat pengaruh kuat anatara suhu permukaan laut dan klorofil-a terlihat dari koefisien korelasi (R) 0,73 dan koefisiesien determinasi (R2) 0,530. Hal ini menjelaskan bahwa suhu permukaan laut di kawasan pantai utara pulau Morotai berpengaruh terhadap klorofil-a sebesar 53% selebihnya dipengaruhi oleh faktor lain. Hasil overlay menunjukan prediksi potensi zona penangkapan ikan (fishing ground) pada musim timur dan peralihan 1 lebih berfokus pada area utara pulau Morotai.

Abstract

The marine and fishery sector is one of the leading sectors and the main driving force that builds the regional economy of the Maluku province, especially in the provision of protein feed ingredients and can improve the welfare of the community, especially fishermen groups, most of whom live in coastal areas. The purpose of this community service activity is to socialize protected fish species for tuna fishing communities. This community service activity was carried out on December 24-25 2022. Community service activity being carried out in the Waiyoho Kawa Village, West Seram Regency. Implementation of activities through several stages, namely: location survey, in-depth interviews, outreach and evaluation. The results of community service can increase the knowledge and insight of tuna fishermen in Waiyoho about protected fish species. The material explained includes (1) 20 protected fish species, (2) the importance of diversity of fish species, (3) sustainable use of fish resources

Abstract

Rumput laut merupakan salah satu komoditi ekspor perikanan yang bernilai ekonomis tinggi. Kandungan yang terdapat pada rumput laut seperti algin, agar dan karagenan memiliki fungsi beragam baik di dunia industri seperti bahan kecantikan, makanan, farmasi pertanian dan tekstil. Manfaat karagenan sendiri sangat penting karena mengandung natrium, magnesium dan kalium yang terdapat pada ester sulfat dari glaktosa. Penelitian ini bertujuan untuk mengetahui faktor-faktor lingkungan perairan bagi pertumbuhan rumput lau jenis Eucheuma cottoni sebagai daya dukung ekonomi masyrakat pesisir. penilitian ini dilaksanakan pada bulan Januari 2023 di Desa Wael Kecamatan Seram Bagian Barat. Metode pengambilan sampel menggunakan pendekatan RAL. Hasil parameter fisik kimia oseanografi yang dipeoleh menunjukan daerah perairan budidaya rumput laut jenis Eucheuma cottoni masih dalam ambang batas yang sesuai. Kualitas perairan diantaranya DO 4,46-4,45 Mg/L, suhu 27,2oC-28,4oC, salinitas 26-30 ‰, pH 6,9, kedalaman 2-3 m, kecerahan 1,25-2,5 m, COD 0,22-0,45, nitrat 0,22-0,23 mg/L.

Abstract

Mangrove merupakan kawasan ekosistem yang memiliki peran penting dalam kawasan pesisir. Kawasan mangrove juga menjadi salah satu kawasan yang paling rentan terhadap tekanan pemanfaatan. Informasi yang berkaitan dengan pemetaan luasan area mangrove talah banyak dilakukan di kawasan timur Indonesia khususnya kawasan maluku dan sekitarnya. Penelitian ini menggunakan metode NDVI yang bertujuan untuk mengetahui nilai kerpatan vegetasi mangrove berdasarkan tingkat kehijauan vegetasi. Data yang digunakan adalah data Landsat-8 tahun 2013 dan citra Sentinel 2B tahun 2023. Hasil penelitian yang diperoleh citra Landsat-8 mampu mememetakan rentang vegetasi mangrove menggunakan pendekatan NDVI dengan baik dan total hasil tutupan lahan yang diperoleh adalah 40,24 Ha. Sedang untuk citra Sentinel 2B memperoleh hasil tutupan rentang mangrove dengan pendekatan metode NDVI sebesar 44,35 Ha. Perubahan kerapatan vegetasi mangrove di kawasan teluk Ambon sangat dipengaruhi oleh aktivitas manusia yang menjadi indikator utama.

Abstract

The declining condition of global fish stocks threatens the sustainability of the resource. Periodic assessments must address this wisely, especially on economically important fish. This study aims to assess the stock of Tylosurus sp. for sustainable management. Length measurements were taken from fishermen's catches over four months. The analysis was carried out using the TropFishR package in the R program. The results showed that the stock of Tylosurus sp. was underfished with the current exploitation rate at (E=0.48). The total mortality is (Z=1.47 year-1), natural mortality is (M=0.77 year-1), and fishing mortality is (F=0.70 year-1). From the modelling results, the maximum catch can be done up to 1.5 year-1, with the length at the first capture of Tylosurus sp. being 63.3 cm. So, with the current stock condition, fishing can still be increased as long as fishermen need to pay attention to the length of fish caught, which should not be less than the value of the first capture.

Abstract

Penipisan stok ikan pada perikanan dunia saat ini menjadi perhatian yang serius karena mengancam keberlanjutan sumberdaya tersebut. Penilaian stok ikan tidak pernah dilakukan karena data yang terbatas. Namun, permasalahan ini dapat diatasi dengan memahami aspek biologi ikan, khususnya parameter populasi. Penelitian ini bertujuan untuk mengetahui kondisi stok ikan pada perikanan yang minim data penangkapan untuk pengelolaan berkelanjutan. Data panjang ikan Decapterus macarellus sebagai tangkapan utama dikumpulkan untuk memperkirakan parameter pertumbuhan, mortalitas dan eksploitasi dengan Paket TropFishR yang dikembangkan pada program R sehingga cukup handal. Hasil penelitian menunjukkan bahwa stok berada pada kondisi underfished. Tingkat eksploitasi berada di angka (E = 0,30), mortalitas total sebesar (Z = 1.52), mortalitas alami sebesar (M = 1,06) dan mortalitas penangkapan sebesar (F = 0,46). Parameter pertumbuhan von Bertalanffy terdiri dari panjang asimptotik (L∞ = 30 cm), koefisien pertumbuhan (K = 0,7), dan indeks kinerja pertumbuhan (Φ’ = 2,81). Tingkat eksploitasi saat ini masih rendah dibawah eksploitasi optimum (Eopt = 0,53) dan penangkapan optimum (Fopt = 2,92). Pemanfaatan masih mungkin ditingkatkan dengan selalu mengontrol masukan dan luaran serta penangkapan panjang dewasa pertama.

Abstract

The utilization of skipjack tuna bone waste from this community service activity aims to raise awareness of the Laha Village community in Ambon Bay about the importance of preserving the surrounding environment in order to avoid environmental pollution in the form of bad odors from fish bone waste that is simply thrown away. This fish bone waste can come from households or home industries. The method used in this community service is Observation, participation and training. This community service was attended by 41 people consisting of lecturers and the surrounding community and was carried out smoothly according to the prepared activity plan. This fish bone flour making training activity can increase the empowerment of the local community to become more independent in utilizing fish bone waste that has economic value so that it can increase family income.
