UTILIZATION STATUS OF RAINBOW PRAWN (Parapenaeopsis stylifera) RESOURCE IN MUKOMUKO WATERS, BENGKULU
Full text linkShrimp resources in Mukomuko waters have been exploited by minitrawl since the 1980s. High fishing pressure has been reported due to intensive trawling in a relatively small fishing area. Appropriate management measures are needed to maintain the sustainability of the shrimp resource. The aim of this study was to assess the exploitation status of the shrimp (Parapenaeopsis stylifera) as a basic information for sustainable shrimp management. A simple random sampling technique was used to sample the shrimp. The results showed that female shrimp dominated the catch of kiddy shrimp in Mukomuko waters. The growth pattern of kiddy shrimp showed a negative allometric pattern. The gonadal maturity level (GML/TKG) of kiddy shrimp was dominated by TKG II and TKG III categories. The value of fishing mortality (F) for the growth parameters of Kiddy shrimp was higher than natural mortality (M). The exploitation rate (E) of Kiddy shrimp was 0.78. The SPR value of kiddy shrimp was 0.21 or 21% moderate or close to overexploitation. This study recommends three management options: replacing shrimp trawls with environmentally friendly fishing gear, opening and closing fishing areas and seasons, and reducing fishing effort

UTILIZATION OF MARICULTURE FISHERY RESOURCES IN AMBON BAY THROUGH GOVERNMENT POLICIES AND YOUTH INVOLVEMENT
Full text linkThe utilization of mariculture fisheries resources in Ambon Bay faces several challenges, including technological limitations, limited market access, and suboptimal government policies. The Ambon City Government and the Maluku Provincial Government have designated this area for marine aquaculture development. Youth involvement is a crucial aspect, as young people serve as partners in the implementation of government policies. This study aims to identify the forms of youth involvement, government policies, and the utilization practices of mariculture fisheries resources in Ambon Bay. Data collection was conducted through interviews with 51 respondents. The identified forms of mariculture fisheries resource utilization include seaweed farming and fish cultivation using floating net cage systems. Youth involvement was categorized as follows: 5.9% as business owners, 68.6% as members of business groups, and 25.5% as laborers. Government policy interventions in the area include the provision of assistance or grants in the form of fish seed, feed, supporting facilities, and training by the Ministry of Marine Affairs and Fisheries, the Maluku Provincial Government, the Ambon City Government, as well as village and sub-district governments. These entities consistently provide support in the form of production facilities for fish farming using floating net cage systems. Government policies on youth empowerment need to be implemented comprehensively, beginning with the preparation of human resources (youth), the development of adequate competencies and skills, and the provision of accessible business capital. These efforts aim to encourage greater youth involvement in the utilization of mariculture fisheries resources in Ambon Bay
BIOECOLOGY OF LOKAN CALM (Geloina erosa) IN THE MANGROVE ECOSYSTEM OF BURUK BAKUL VILLAGE, BUKIT BATU DISTRICT, BENGKALIS REGENCY, RIAU PROVINCE
Full text linkMangrove ecosystems are characterized by the high diversity of associated biota found, such as sea scallops. Sea scallops are filter feeders and suspension feeders that live at the bottom of the waters by burying themselves in sediment. This study aims to determine the biological aspects of sea scallops (morphometrics, density, distribution, and growth) and ecological aspects (mangrove vegetation structure and knowing the condition of sediment fractions and organic matter) in Buruk Bakul Village, Bukit Batu District, Bengkalis Regency, Riau Province. Sampling was carried out on transects containing 9 plots measuring 1 x 1 m² with a depth of 30 cm and a distance between transects of 100 m. Sampling and observation were carried out 3 times with an interval of 2 weeks. The results showed that the morphometric size of sea scallops varied. The density value of lokan clams ranges from 150 ind/ha to 2,700 ind/ha, with the highest lokan density at station I, natural mangrove forest conditions, and no community activities. The distribution pattern of lokan clams is categorized as uniform with an average value of <1. The growth pattern of lokan clams shows a negative allometric pattern, namely b <3. The highest density of mangrove vegetation is at station I, with 1,522 trees/ha, in a good category. The highest sediment fraction is the mud fraction, ranging from 30.24% to 84.6%. The highest organic matter content is at station I with a value of 28.37%. The results of the study showed that the density, growth, and morphometrics of lokan clams in Buruk Bakul Village were significantly influenced by the ecological conditions of the mangrove forest, especially the density of mangrove vegetation, substrate composition, and concentration of organic matter in the sediment

Full text linkPelabuhan Perikanan Nusantara (PPN) Brondong menjadi salah satu penyumbang hasil tangkapan cumi-cumi yang cukup besar. Namun, masih bergantungnya hasil tangkapan di alam memberikan gambaran bahwa resiko eksploitasi dan penangkapan berlebih. Kondisi nelayan Indonesia yang identik dengan kemiskinan diperlukan pemanfaatan cumi-cumi secara berkelanjutan sehingga upaya untuk menjaga kelestarian sumber daya perikanan tetap dapat memberikan manfaat secara ekonomi bagi nelayan. Tujuan dari penelitian ini adalah untuk menganalisis tingkat biomassa, hasil tangkapan, upaya penangkapan, rente ekonomi cumi-cumi di PPN Brondong pada kondisi Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), dan Open Access (OA) dengan menggunakan metode analisis bioekonomi Gordon-Schaefer. Hasil penelitian yang dilakukan didapatkan bahwa kondisi yang memberikan keuntungan secara maksimal adalah pada kondisi Maximum Economic Yield (MEY) dengan nilai rente ekonomi terbesar diantara ketiga kondisi pengelolaan bioekonomi. Sedangkan, kondisi yang memberikan potensi lestari secara maksimal adalah kondisi Maximum Sustainable Yield (MSY) dengan nilai hasil tangkapan terbesar. Hasil perbandingan analisis pada tiga kondisi pengelolaan bioekonomi dengan kondisi aktual menunjukkan bahwa upaya penangkapan secara aktual telah mencapai status tangkap lebih secara ekonomis (economic overfising).Pelabuhan Perikanan Nusantara (PPN) Brondong is one of the major contributors to the squid catch. The reliance on natural catches illustrates the risk of exploitation and overfishing. The condition of Indonesian fishermen, which is synonymous with poverty, requires sustainable utilization of squid so that efforts to preserve fisheries resources can still provide economic benefits for fishermen. The purpose of this study was to analyze the level of biomass, catch, fishing effort, economic rent of squid at PPN Brondong under the conditions of Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), and Open Access (OA) using the Gordon-Schaefer bioeconomic analysis method. The results of the research conducted found that the condition that provides maximum profit is in the Maximum Economic Yield (MEY) condition with the largest economic rent value among the three bioeconomic management conditions. Meanwhile, the condition that provides maximum sustainable potential is the Maximum Sustainable Yield (MSY) condition with the largest catch value. The results of the comparison analysis on the three bioeconomic management conditions with the actual conditions show that the actual fishing effort has reached the status of economic overfishing

This study analyzes land use changes in Jungut Batu Village, Nusa Lembongan, using secondary data and Google Earth Pro, revealing a significant shift from seaweed cultivation to tourism development between 2009 and 2020, with a temporary reversion to seaweed cultivation during the pandemic. This transformation highlights evolving economic dynamics and environmental impacts. While the shift towards ecotourism represents a potential evolution in sustainable land use, the adverse effects of mass tourism necessitate a transition to eco-friendly and sustainable practices. Effective collaboration among communities, tourism stakeholders, and government, as well as further research, is crucial to developing a genuinely sustainable ecotourism model for Nusa Penida with contribution of society has accpet for last moment
Kebijakan Berbasis Partisipasi Masyarakat Untuk Mitigasi Bencana Banjir Rob di Kecamatan Teluk Betung Timur, Kota Bandar Lampung
Full text linkBanjir rob di Kecamatan Teluk Betung Timur, Kota Bandar Lampung, terjadi secara berulang dan menimbulkan dampak sosial-ekonomi yang signifikan. Namun, studi terdahulu cenderung fokus pada aspek teknis penanggulangan banjir, sementara tingkat partisipasi masyarakat yang menjadi kunci keberhasilan mitigasi berbasis komunitas masih jarang diteliti secara komprehensif. Kekosongan penelitian ini menyebabkan kebijakan mitigasi yang ada cenderung bersifat top-down dan kurang melibatkan warga sebagai aktor utama. Penelitian ini bertujuan untuk menganalisis tingkat partisipasi masyarakat dalam upaya mitigasi banjir rob serta mengidentifikasi faktor-faktor penghambatnya dengan menggunakan kerangka tangga partisipasi Arnstein. Metode penelitian dilakukan melalui survei pada 60 responden dari empat kelurahan terdampak, dilengkapi wawancara mendalam dengan tokoh masyarakat dan perwakilan pemerintah daerah. Hasil penelitian menunjukkan bahwa partisipasi masyarakat berada pada level consultation, di mana warga hanya memiliki ruang untuk menyampaikan pendapat tanpa peran dalam pengambilan keputusan. Rendahnya tingkat partisipasi ini dipengaruhi oleh minimnya kesadaran risiko, keterbatasan akses informasi, serta kurangnya fasilitasi dari pemerintah. Berdasarkan temuan tersebut, studi ini merekomendasikan pembentukan forum komunikasi warga berbasis desa, peningkatan edukasi dan literasi kebencanaan, serta optimalisasi peran LSM untuk memperkuat keterlibatan warga. Temuan ini memberikan kontribusi bagi perumusan kebijakan mitigasi banjir rob yang lebih inklusif, partisipatif, dan berkelanjutan. Title: Public Participation-Based Policy For Mitigation of Rob Flood Disaster In Teluk Betung Timur District, Bandar Lampung City Tidal flooding in East Teluk Betung District, Bandar Lampung City, occurs repeatedly and has significant socio-economic impacts. However, previous studies have tended to focus on the technical aspects of flood mitigation, while the level of community participation, key to the success of community-based mitigation, has rarely been comprehensively studied. This research gap has resulted in existing mitigation policies being top-down and lacking citizen involvement as key actors. This study aims to analyze the level of community participation in tidal flood mitigation efforts and identify inhibiting factors using Arnstein’s ladder of participation framework. The research method used was a survey of 60 respondents from four affected villages, supplemented by in-depth interviews with community leaders and local government representatives.The results indicate that community participation is at the consultation level, where residents only have the opportunity to express their opinions without a role in decision-making. This low level of participation is influenced by minimal risk awareness, limited access to information, and inadequate facilitation from the government. Based on these findings, this study recommends the establishment of village-based citizen communication forums, increased disaster education and literacy, and optimizing the role of NGOs to strengthen community involvement. These findings contribute to the formulation of more inclusive, participatory, and sustainable tidal flood mitigation policies
