KEBIJAKAN INOVASI TEKNOLOGI AERATOR PORTABEL UNTUK MENINGKATKAN DAYA TAHAN HIDUP RAJUNGAN DAN PENDAPATAN NELAYAN BUBU DI TELUK JAKARTA
Get PDFRajungan (Portunus pelagicus) merupakan komoditas perikanan bernilai ekonomi tinggi yang memiliki peran strategis dalam meningkatkan pendapatan nelayan kecil di Indonesia. Salah satu tantangan utama dalam rantai nilai rajungan adalah rendahnya tingkat kelangsungan hidup hasil tangkapan sebelum tiba di pelabuhan, yang berdampak pada penurunan nilai jual. Penelitian ini bertujuan untuk mengevaluasi efektivitas teknologi aerator portabel dalam meningkatkan daya tahan hidup rajungan pada kapal bubu sebagai upaya kebijakan inovatif yang berdampak pada ekonomi nelayan. Metode eksperimen dilakukan dengan membandingkan dua perlakuan: bak kontrol tanpa aerator dan bak perlakuan dengan aerator, selama lima trip penangkapan di Perairan Teluk Jakarta. Hasil analisis statistik menunjukkan terdapat perbedaan signifikan (p = 0,007) dalam tingkat kelangsungan hidup rajungan antara dua perlakuan, dengan angka survival mencapai 100% pada perlakuan aerator. Temuan ini menunjukkan bahwa teknologi aerator portabel dapat diadopsi sebagai bagian dari strategi kebijakan peningkatan kualitas pasca-tangkap dan peningkatan kesejahteraan nelayan rajungan. Diperlukan dukungan kebijakan dalam bentuk penyuluhan teknologi dan bantuan akses peralatan bagi nelayan kecil. The blue swimming crab (Portunus pelagicus) is a high-value fishery commodity that plays a strategic role in enhancing the income of small-scale fishers in Indonesia. One of the key challenges in the crab value chain is the low survival rate of catches before landing, which significantly reduces market value. This study aims to evaluate the effectiveness of portable aerator technology in improving the survival rate of crabs on trap boats, as part of an innovative policy effort to enhance fisher livelihoods. An experimental method was employed, comparing two treatment groups: a control tank without an aerator and a treatment tank equipped with a portable aerator, over five fishing trips in Jakarta Bay. Statistical analysis revealed a significant difference in survival rates between the two treatments (p = 0.007), with the aerated group achieving a 100% survival rate. These findings suggest that portable aerator technology can be adopted as a viable strategy for improving post-harvest quality and supporting the economic resilience of blue swimming crab fishers. Policy support in the form of technology outreach and improved access to equipment for small-scale fishers is recommended
FAKTOR-FAKTOR YANG MEMPENGARUHI PERFORMA PENGELOLAAN SUMBER DAYA TERUMBU KARANG DI PULAU PAHAWANG, KABUPATEN PESAWARAN
Get PDF Ekosistem terumbu karang banyak dimanfaatkan sebagai destinasi wisata bahari khususnya snorkeling. Ekosistem terumbu karang di Pulau Pahawang menghadapi tekanan akibat aktivitas wisata yang tidak ramah lingkungan. Kerangka kerja Institutional Analysis Development (IAD) digunakan sebagai pendekatan untuk mengevaluasi pengaruh variabel eksogen yaitu kondisi biofisik, atribut komunitas dan aturan yang digunakan (rules-in-use) terhadap interaksi antar aktor dan pengelolaan ekowisata dengan menggunakan metode analisis structural equation modeling-partial least square (SEM-PLS) untuk menguji hubungan kausal antar variabel laten. Hasil menunjukkan bahwa pengelolaan ekowisata dan rules-in-use memiliki pengaruh signifikan terhadap performa pengelolaan, sedangkan peran aktor belum menunjukkan kontribusi signifikan. Atribut komunitas terbukti mempengaruhi aktor, terutama melalui kesamaan karakteristik dan tingkat pemahaman masyarakat. Meskipun terdapat inisiasi konservasi antara pihak akademisi dan masyarakat, implementasi pengelolaan masih terkendala oleh minimnya koordinasi antar pihak, dominasi aktor eksternal, serta keterbatasan kapasitas lokal. Edukasi dan pemberdayaan masyarakat menjadi kunci untuk penguatan pengelolaan ekowisata berkelanjutan. Penelitian ini menekankan pentingnya sinergi antar stakeholder dan penerapan aturan yang efektif dalam mendukung pelestarian terumbu karang serta peningkatan kesejahteraan masyarakat pesisir.Pahawang Island, Pesawaran Regency, Lampung Province has a coral reef ecosystem and is used as a primary resource for marine tourism, especially for snorkeling. The coral reef ecosystem on Pahawang Island faces pressure from environmentally unfriendly tourism. The Institutional Analysis Development (IAD) framework is used as an approach to evaluate the influence of exogenous variables, namely biophysical conditions, community attributes and rules-in-use on interactions between actors and ecotourism management using the structural equation modeling-partial least square (SEM-PLS) analysis method to test the causal relationship between latent variables. The results show that ecotourism management and rules-in-use have a significant influence on management performance, whereas the role of actors does not. Community attributes have been shown to influence actors, especially through similarities in their characteristics and levels of community understanding. Although there is a conservation initiative between academics and the community, its implementation is still constrained by limited coordination among parties, the dominance external actors, and limited local Capacity. Community education and empowerment are the keys to strengthening sustainable ecotourism management. This study emphasizes the importance of synergy between stakeholders and the implementation of effective regulations to support coral reef conservation and improving the welfare of coastal communitie
KECUKUPAN KONSUMSI IKAN PADA RUMAH TANGGA DI NUSA TENGGARA TIMUR: PENDEKATAN REGRESI LOGISTIK
Get PDFKonsumsi ikan di Nusa Tenggara Timur (NTT) masih sangat rendah, walaupun hasil perikanannya melimpah. Kondisi ini menyebabkan kebutuhan protein tidak terpenuhi, yang kemudian menimbulkan ancaman gizi buruk (stunting) yang cukup parah . Oleh karena itu, diperlukan upaya untuk meningkatkan konsumsi ikan pada rumah tangga sampai memenuhi batas konsumsi yang cukup. Penelitian ini bertujuan untuk mengetahui gambaran kecukupan konsumsi ikan dan menganalisis faktor-faktor yang memengaruhi kecukupan konsumsi ikan pada rumah tangga di NTT. Periode penelitian ini adalah tahun 2024 dengan memanfaatkan data sekunder berupa data mikro SUSENAS Maret 2024 yang bersumber dari Badan Pusat Statistik. Data dianalisis dengan pendekatan model regresi logistik. Hasil penelitian menunjukkan bahwa mayoritas rumah tangga di NTT belum mengonsumsi ikan dalam jumlah yang cukup. Rumah tangga di wilayah perkotaan, termasuk kelas pendapatan menengah-atas, atau beranggotakan 1-5 orang memiliki kecenderungan lebih tinggi untuk mengonsumsi ikan dalam jumlah cukup. Selain itu, kepala rumah tangga yang mengakses internet, bekerja pada sektor perikanan, berusia di atas 40 tahun, atau seorang perempuan juga meningkatkan kecenderungan rumah tangga untuk mengonsumsi ikan dalam jumlah cukup. Penelitian ini memberikan rekomendasi strategis dalam mendukung Gerakan Memasyarakatkan Makan Ikan (Gemarikan) di NTT, meliputi pembangunan pasar ikan murah, subsidi harga ikan, serta sosialisasi pentingnya konsumsi ikan.TITLE: ADEQUACY OF HOUSEHOLD FISH CONSUMPTION IN EAST NUSA TENGGARA: A LOGISTIC REGRESSION APPROACHFish consumption in East Nusa Tenggara (NTT) remains very low despite the abundance of fisheries resources. This condition leads to inadequate protein intake, which poses a serious threat of malnutrition, particularly stunting. Therefore, efforts are needed to increase household fish consumption to an adequate level. This study aims to describe the adequacy of household fish consumption and to analyze the factors that inffuence it in households across NTT. The study utilizes secondary data from the March 2024 SUSENAS microdata, provided by Statistics Indonesia (BPS). The data are analyzed using a logistic regression model. The results show that the majority of households in NTT do not consume fish at an adequate level. Households located in urban areas, those in the middle-to-upper income classes, or those with 1–5 members are more likely to consume fish adequately. In addition, households headed by individuals who access the internet, work in the fisheries sector, are over 40 years old, or are female also have a higher likelihood of adequate fish consumption. This study provides strategic recommendations for supporting the Gerakan Memasyarakatkan Makan Ikan (Gemarikan) in NTT, including the development of affordable fish markets, the provision of fish price subsidies, and public campaigns on the importance of fish consumption

Analisis Kebijakan Zona Inti Kawasan Konservasi Perairan, Pesisir, dan Pulau-Pulau Kecil di Kepulauan Seribu
Get PDFZona inti Kawasan Konservasi Perairan Pesisir dan Pulau-Pulau Kecil (KKP3K) dapat menghadapi ancaman antropogenik alami maupun karena dampak kebijakan dan ego sektoral. Tujuan penelitian ini untuk mengkaji aspek ekologi, sosial, dan ekonomi di kawasan konservasi Kepulauan Seribu sehingga dapat menghasilkan skenario terbaik setelah terbitnya Peraturan Pemerintah Nomor 27 tahun 2021 tentang perubahan zona inti KKP3K. Penelitian ini menggunakan metode kuantitatif dengan pendekatan empiris. Data primer diperoleh melalui Focus Group Discussion (FGD) dan wawancara serta data sekunder dari studi dokumentasi dengan skenario menggunakan analisis trade-off. Hasil penelitian menunjukkan skenario terbaik (rata-rata 57) adalah skenario B (zona inti digunakan untuk ekowisata berkelanjutan) karena mengedepankan asas keberlajutan lingkungan sebagai salah satu aset dalam mendorong pariwisata. Skenario A (zona inti tidak perlu dirubah) menjadi alternatif kedua karena pembatasan aktifitas melalui sistem zonasi positif terhadap keberlanjutan ekologi lingkungan, sedangkan skenario C (zona inti digunakan untuk ekonomi) menggambarkan perubahan aspek ekologi, ekonomi dan sosial yang berdampak negatif terhadap ekologi dan hanya berimplikasi positif terhadap aspek ekonomi dan sosial. Dasar legalitas dari perubahan zona inti yang digunakan untuk proyek strategis nasional akan menimbulkan dampak sosial dan ekologi, oleh karena itu perubahan terhadap zona inti mestinya tidak perlu dilakukan kecuali dapat memberikan alternatif yang bermuara pada penyelarasan dan peningkatan aspek ekologi, ekonomi, dan sosial pada kawasan tersebut. Title: Policy Analysis of Core Zone in Marine Conservation Areas, Coastal and Small Islands in Seribu Island The core zone of the Coastal Marine Protected Area and Small Islands (KKP3K) can face anthropogenic, natural threats, as well as due to the impact of sectoral policies and egos. The purpose of this study is to examine the ecological, social, and economic aspects of the Thousand Islands conservation area so that it is expected to produce the best scenario related to the issuance of Government Regulation Number 27 of 2021 concerning changes in the KKP3K core zone. This research uses quantitative methods with an empirical approach and uses primary data obtained through Focus Group Discussion (FGD) and interviews as well as secondary data from documentation studies screened with scenarios using trade-off analysis. The results showed that the best scenario (average 57) was scenario B (core zone used for sustainable ecotourism) because it prioritized the principle of environmental sustainability as one of the assets in encouraging tourism. Scenario A (core zone does not need to be changed) is the second alternative because restrictions on activities through the zoning system positivelly on the sustainability of environmental ecology, while scenario C (core zone is used for economics) describes changes in ecological, economic and social aspects that can produce negative impacts on ecology and only have positive implications for economic and social aspects. The legality basis of changes to core zones used for national strategic projects will have social and ecological impacts, therefore changes to core zones should not be necessary unless they provide alternatives that lead to alignment and improvement of ecological, economic, and social aspects of the region.
STATISTICAL AND MACHINE-LEARNING APPROACHES FOR MAPPING BIGEYE TUNA FISHING OPTIMALITY IN THE BANDA SEA
No full textGiven the complexity of the Banda Sea, which has rapidly changing environmental factors, studies are needed to determine the optimal location for important fishing, such as bigeye tuna (BET). To map optimal fishing locations, statistical and machine-learning methods are used through an understanding of the dynamics of chlorophyll-a (Chlo) concentrations and sea surface temperature (SST) and fish catch data as key factors. Using the fishing logbook and oceanographic data from 2014 to 2022, this study applies the methods of generalized Additive Model (GAM) and Empirical Cumulative Distribution Function (ECDF) to analyze the effect of Chlo and SSTs on Catch per Unit Efforts (CPUEs). Due to GAM's suboptimal performance, ECDF is chosen as the primary method. Determining the optimal value range using k-means and the elbow method showed an optimal Chlo range of 0.087–0.30 mg/m³ and SST of 29.46–30.45°C. The analysis showed the best catching conditions from January to March. These findings support sustainable fishing by providing a monthly map of optimal fishing zones, helping fishers adapt to dynamic conditions. Further research is suggested to integrate real-time data and advanced techniques to improve location accuracy

Get PDFIkan sidat termasuk ikan konsumsi potensial yang memiliki daya tarik baik di dalam maupun luar negeri. Budidaya benih ikan sidat (stadia glass eel) memiliki tantangan tersendiri. Salah satunya adalah wadah pemeliharaan yang digunakan. Kolam beton sering digunakan sebagai wadah pemeliharaan, namun dibutuhkan biaya yang cukup besar dalam pembuatannya. Alternatif yang digunakan dalam budidaya benih ikan sidat yaitu menggunakan kolam terpal. Tujuan dari penelitian ini untuk mengidentifikasi kinerja pertumbuhan benih ikan sidat pada stadia glass eel pada media kolam terpal. Variabel yang diamati dalam penelitian ini meliputi pertumbuhan berat mutlak, pertumbuhan panjang mutlak, laju pertumbuhan mutlak dan tingkat kelangsungan hidup. Hasil yang didapatkan selama kegiatan penelitian dengan masa pemeliharaan 25 hari menunjukkan bahwa benih ikan sidat mengalami pertumbuhan dengan pertumbuhan tertinggi terdapat pada kolam A. Namun kolam A menunjukkan tingkat kelangsungan hidup ikan sidat terendah, yakni sebesar 82,5%. Kolam B dan C masing-masing memiliki tingkat kelangsungan hidup sebesar 98,4% dan 99,8%. Secara keseluruhan dalam masa pemeliharaan di kolam terpal, benih ikan sidat dapat tumbuh dan memiliki tingkat kelangsungan hidup yang lebih tinggi dibandingkan tingkat kelangsungan hidup pada kolam beton berdasarkan penelitian sebelumnya.Eel (Anguilla spp.) is considered a potential species for human consuption with significant market appeal both domestically and internationally. However, culturing juvenile eels, specifically at the glass eel stage, presents unique challenges. One such challenge lies in the choice of rearing containers. Concrete ponds are frequently used for this purpose but incur substantial construction costs. As an alternative, tarpaulin ponds offer a more cost-effective option for glass eel culture.The objective of this study was to evaluate the growth performance of glass eels reared in tarpaulin ponds. The variables observed included absolute weight gain, absolute length gain, absolute growth rate, and survival rate. Over a 25-day rearing period, the results indicated that the glass eels exhibited growth, with the highest growth observed in Pond A. However, Pond A had the lowest survival rate for eel larvae, at 82.5%. In contrast, Pond B and Pond C demonstrated significantly higher survival rates of 98.4% and 99.8%, respectively. Overall, during the rearing period in tarpaulin ponds, the glass eels showed positive growth and higher survival rates compared to those previously reported for concrete ponds
Analisis Kelayakan Usaha dan Efisiensi Faktor Produksi Budi Daya Udang Vaname (Litopennaeus Vannamei) di Kabupaten Barru
Get PDFPerbedaan sistem budi daya dan kebiasan lokal petambak tanpa perhitungan input-output yang rasional berpotensi menurunkan efisiensi dan kelayakan usaha udang vaname. Penelitian ini bertujuan menganalisis kelayakan usaha dan efisiensi faktor produksi budi daya udang vaname di Kabupaten Barru pada dua Desa Sentra, yaitu Desa Corawali (tradisional) dan Desa Lawallu (semi-intensif). Metode yang digunakan adalah metode kuantitatif melalui analisis kelayakan finansial serta analisis efisiensi faktor produksi menggunakan fungsi produksi Cobb-Douglas yang dilanjutkan dengan perhitungan efisiensi alokatif. Hasil penelitian menunjukkan bahwa usaha budi daya di kedua desa layak diusahakan (R/C > 1), namun Desa Lawallu memiliki Net Profit lebih besar dan Payback Period lebih cepat dibandingkan Desa Corawali. Luas lahan dan jumlah benih merupakan faktor yang paling berpengaruh terhadap produksi. Analisis efisiensi alokatif menunjukkan bahwa pemanfaatan lahan di kedua desa cenderung berlebihan, sementara jumlah benih di Desa Lawallu masih perlu dimanfaatkan secara optimal. Oleh karena itu, diperlukan pengaturan kembali skala lahan dan padat tebar sesuai daya dukung tambak, serta dukungan pemerintah melalui perbaikan fasilitas irigasi di Desa Corawali dan pelatihan pengelolaan pakan serta teknologi budi daya ramah lingkungan untuk mendukung produksi yang berkelanjutan.Title: Analysis of Business Feasibility and Optimization of Production Factors of Vaname Shrimp Cultivation in Barru RegencyDifferences in cultivation systems and local practices of farmers without rational input-output calculations have the potential to reduce the efficiency and feasibility of vannamei shrimp farming. This study aims to analyze the feasibility of the business and the efficiency of production factors of vannamei shrimp farming in Barru Regency in two central villages, namely Corawali Village (traditional) and Lawallu Village (semi-intensive). The method used is a quantitative method through financial feasibility analysis and production factor efficiency analysis using the Cobb-Douglas production function followed by allocative efficiency calculations. The results show that the cultivation business in both villages is feasible (R/C > 1), but Lawallu Village has a greater Net Profit and a faster Payback Period than Corawali Village. Land area and number of seeds are the most influential factors on production. The allocative efficiency analysis shows that land utilization in both villages tends to be excessive, while the number of seeds in Lawallu Village still needs to be utilized optimally. Therefore, it is necessary to rearrange the land scale and stocking density according to the carrying capacity of the pond, as well as government support through improving irrigation facilities in Corawali Village and training in feed management and environmentally friendly cultivation technologies to support sustainable production

Get PDFPada tahun 2021, nilai ekspor tuna sirip kuning Indonesia mencapai USD 5,179 juta, menjadikannya komoditas tuna dengan nilai ekspor tertinggi di antara lima jenis tuna yang diperdagangkan secara global. Namun demikian, masih terdapat sejumlah tantangan, seperti penurunan volume ekspor, terpusatnya pasar pada beberapa negara utama, serta melemahnya daya saing di pasar tradisional. Oleh karena itu, perlu dilakukan perluasan pasar ekspor ke negara-negara nontradisional. Penelitian ini menganalisis faktor-faktor yang memengaruhi volume ekspor tuna sirip kuning Indonesia ke pasar tersebut dengan menggunakan data panel periode 2016–2021 dari UN Comtrade dan World Bank, mencakup sepuluh negara tujuan nontradisional: Britania Raya, Italia, Vietnam, Tiongkok, Hong Kong, Malaysia, Filipina, Singapura, Uni Emirat Arab, dan Australia. Analisis dilakukan dengan regresi data panel menggunakan pendekatan Random Effect Model (REM). Hasil penelitian menunjukkan bahwa harga ekspor tuna sirip kuning Indonesia dan harga pesaing berpengaruh negatif signifikan terhadap volume ekspor, sedangkan indeks Revealed Symmetric Comparative Advantage (RSCA) dan nilai tukar berpengaruh positif. Sementara itu, variabel jarak ekonomi tidak berpengaruh signifikan. Temuan ini menegaskan bahwa daya saing merupakan faktor utama dalam peningkatan kinerja ekspor tuna sirip kuning Indonesia. Oleh karena itu, diperlukan upaya menjaga stabilitas harga melalui pengendalian pasokan dan biaya produksi, peningkatan mutu dan pemenuhan standar internasional, serta penguatan kerja sama perdagangan dengan negara nontradisional untuk mengurangi hambatan tarif dan nontarif.Title: Export Performance Analysis of Indonesian Yellowfin Tuna in Nontraditional Countries In 2021, Indonesia’s yellowfin tuna exports reached a value of USD 5.179 million, making it the highest among the five tuna species traded internationally. However, several challenges persist, including a declining export volume, concentration in a few destination countries, and weakening competitiveness in major markets. To address this, expanding exports to nontraditional countries has become essential. This study analyzes the determinants influencing Indonesia’s yellowfin tuna export volume to such emerging markets. Panel data covering 2016–2021 from UN Comtrade and the World Bank were employed, encompassing ten nontraditional destinations: the United Kingdom, Italy, Vietnam, China, Hong Kong, Malaysia, the Philippines, Singapore, the United Arab Emirates, and Australia. Using a Random Effects Model (REM), the results indicate that both Indonesia’s export price and competitors’ prices have a significant negative effect, while the Revealed Symmetric Comparative Advantage (RSCA) index and the exchange rate positively affect export volume. Conversely, economic distance shows no significant impact. These findings highlight that competitiveness is a key driver of Indonesia’s yellowfin tuna export performance. Therefore, maintaining price stability through supply and production cost management, improving quality and international standard compliance, and strengthening trade partnerships with nontraditional markets are recommended to reduce tariff and non-tariff barriers and enhance long-term export sustainability
COMPOSITION OF THE CATCH AND OPERATION OF SONDONG FISH FISHING GEAR IN THE WATERS OF RUPAT STRAIT, DUMAI, RIAU
Get PDFThis study aims to determine the type and composition of the catch, as well as describe the operation of the sondong fishing gear (push net) in the waters of the Rupat Strait, Dumai City, Riau Province. The method used is a descriptive method with quantitative and qualitative approaches. Data collection was carried out through direct observation, interviews with fishermen from KM Camar Laut, and documentation of catches from January to June 2025. The results of the study indicate that the sondong fishing gear has a simple construction with high effectiveness in catching white shrimp (Penaeus sp) as the main catch. In addition, there are bycatch in the form of senangin fish, gulama fish, sole fish, flatfish, black pomfret, swimming crab, sea eel, and tiger shrimp. The discarded catch that has no economic value is dominated by puffer fish (Tetraodon sp). Of the total catch of ±2,437 kg, approximately 43.4% is the main catch, 25.2% is bycatch, and 31.4% is discarded. Although effective, this tool is considered less selective and has the potential to damage the waters bottom. Therefore, sustainable management and monitoring of the use of sondong fishing gear is needed so as not to threaten the sustainability of the marine ecosystem in the area
