Prigi, Trenggalek is a potential fishery area located in the southern part of the East Java. Most fishers in Prigi uses trammel net as a capture device. The purpose of this research is to analyze the correlation of oceanographic parameters on the production of trammel net in Prigi’s fishing ground. The data used in this research are temperature, pH, salinity, velocity of currents, depth, and trammel net production during 35 trips. Oceanographic parameters in the fishing ground are temperature ranges from 26°C - 31°C, pH ranges from 7 – 9, salinity ranges from 25‰ - 35‰, current velocity range 0.13 m/s - 0.39 m/s, and the water depth ranges from 10 - 18 m. Variability from trammel net production are long tongue sole (Cynoglossus sp), crab (Portunus sp), endeavour shrimp (Metapenaeus sp), sea snail (Bufonaria sp), common ponyfish (Leiognathus sp), japanese threadfin bream (Nemipterus sp), squid (Loligo sp), and giant tiger prawn (Penaeus sp) with total production 302.2 kg. Correlation between oceanographic parameters and trammel net production are high for the current velocity with correlation value 0.78, and medium for depth and temperature with correlation value are 0.56 and 0.45, respectively. Correlation between salinity and pH with trammel net production are low and very low with correlation value -0.23 and 0.002, respectively.

Brondong District in Lamongan Regency is one of Indonesia’s coastal zones where shoreline dynamics are highly sensitive to both natural processes and human activities. As coastal development intensifies, shoreline positions in this region exhibit periodic shifts, resulting in either land expansion or loss. Understanding these changes is critical for effective coastal management, regional planning, and risk mitigation. This study analyzed shoreline displacement from 1993 to 2019 and projected shoreline conditions up to 2030. Remote sensing techniques, supported by the Digital Shoreline Analysis System (DSAS), were employed to quantify shoreline movement and calculate accretion and erosion rates through transect-based statistical models. Land-use changes were analyzed using the regional spatial plan and Landsat imagery, validated through field observations. Results indicate that Brondong District experienced predominantly accretional shoreline movement over the study period. Brondong Village showed the most substantial accretion, with an average shoreline shift of 376.12 meters and an annual rate of 14.49 meters, while Lohgung Village exhibited the lowest, with 31.72 meters and 1.22 meters per year. Differences between villages suggest that local geomorphology, sediment supply, and human activities significantly influence coastal change. Projections for 2030 indicate that accretion will continue to dominate, with Brondong Village expected to experience an additional 42.58 meters of shoreline advance at an annual rate of 3.87 meters. Although the projected rate is lower than historical values, continued land accumulation highlights the long-term influence of sediment deposition, tidal processes, and coastal infrastructure. These findings provide valuable insights for sustainable coastal management, planning, and adaptation strategies in rapidly developing coastal zones.

Bangsring Village, Banyuwangi Regency, Indonesia is a coastal tourism area with high ecological and economic potential; however, tourist visitation has declined significantly since 2020, highlighting the need for locally grounded and resilient livelihood innovations. This study aims to evaluate the feasibility and community relevance of lobster aquaculture as a tourism-supporting livelihood strategy using a Community-Based Participatory Research (CBPR) framework. The CBPR process was implemented through collaborative problem identification, participatory planning, joint environmental assessment, and community-led implementation involving the Pesona Bahari Community Group. Water quality parameters and site characteristics were jointly analyzed to inform technology selection. Based on these findings, a circular bottom (base) net-cage system was selected due to its suitability for moderate current conditions, benthic substrates, and its ability to mimic the natural habitat of lobsters. Program implementation included cage construction and deployment, seed stocking, daily maintenance using natural feed, and harvesting after approximately 100 days of rearing. The outcomes indicate increased community capacity in environmentally responsible lobster aquaculture practices and successful production of marketable-sized lobsters under local conditions. Beyond economic diversification, lobster farming activities also function as an educational and experiential attraction, strengthening the integration between aquaculture and coastal tourism. This study contributes a context-specific CBPR-based model for integrating small-scale lobster aquaculture with coastal tourism development. The approach demonstrates practical applicability and potential replicability for other coastal communities seeking sustainable livelihood diversification without compromising ecosystem integrity.

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan sistem budidaya outdoor dan indoor terhadap performa budidaya udang vannamei (Litopenaeus vannamei). Pengamatan dilakukan selama 90 hari atau satu siklus pemeliharaan dengan menggunakan metode observasi langsung, wawancara, serta partisipasi aktif dalam seluruh rangkaian kegiatan budidaya. Parameter yang diamati meliputi kualitas air, yang terdiri atas suhu, salinitas, pH, oksigen terlarut, dan kecerahan perairan. Selain itu, parameter pertumbuhan udang juga diamati, meliputi Average Body Weight (ABW), Average Daily Growth (ADG), Survival Rate (SR), serta Feed Conversion Ratio (FCR) sebagai indikator efisiensi pemanfaatan pakan. Hasil penelitian menunjukkan bahwa sistem budidaya outdoor memiliki kondisi suhu dan salinitas yang lebih mendekati kisaran optimal bagi pertumbuhan udang vannamei. Kondisi tersebut mampu mendukung laju pertumbuhan yang lebih cepat, yang ditunjukkan oleh nilai ABW akhir sebesar 26,35 g dan nilai ADG tertinggi mencapai 0,78 g/hari. Sebaliknya, sistem budidaya indoor menunjukkan laju pertumbuhan yang relatif lebih lambat, namun memiliki tingkat kelangsungan hidup yang lebih tinggi, yaitu sebesar 95%, dibandingkan dengan sistem outdoor yang mencapai 90%. Selain itu, nilai Feed Conversion Ratio (FCR) pada sistem indoor menunjukkan tingkat efisiensi pakan yang lebih baik dibandingkan sistem outdoor. Hal ini mengindikasikan bahwa kondisi lingkungan yang lebih terkendali pada sistem indoor mampu mendukung pemanfaatan pakan secara lebih optimal. Secara keseluruhan, sistem budidaya outdoor lebih unggul dalam meningkatkan pertumbuhan biomassa udang, sedangkan sistem budidaya indoor lebih efektif dalam menjaga tingkat kelangsungan hidup dan stabilitas lingkungan.

Whiteleg shrimp (Litopenaeus vannamei) is one of the leading commodities in Indonesian brackishwater aquaculture due to its high production efficiency and strong market demand. Water quality is a key factor determining culture success, and aeration plays an essential role in maintaining dissolved oxygen (DO) levels while reducing the accumulation of toxic nitrogen compounds such as ammonia and nitrite. This study aimed to evaluate the effects of different aeration systems on water quality and the survival of whiteleg shrimp at the Brackish Water Aquaculture Installation (IBAP) Banjar Kemuning, Sidoarjo, Indonesia. A comparative descriptive study was conducted using two treatments: a complete aeration system consisting of paddle wheels, blowers, and diffusers, and a single aeration system using paddle wheels only. The observed water quality parameters included temperature, pH, salinity, DO, ammonia, nitrite, and nitrate. The results showed that the complete aeration system maintained more stable water quality, characterized by higher DO levels and lower ammonia and nitrite concentrations than the single aeration system. The average survival rate (SR) of shrimp cultured under the complete aeration system was 76.99%, compared with 73.28% in the single aeration system. Overall, the complete aeration system was more effective in improving water quality and enhancing shrimp survival. Nevertheless, unstable water quality conditions, particularly elevated ammonia and nitrite concentrations and low DO levels, were associated with the occurrence of White Spot Syndrome Virus (WSSV). These findings highlight the importance of optimizing aeration as part of an integrated water quality management strategy to support sustainable whiteleg shrimp aquaculture.
