Abstract

The Bali Strait connects the Java Sea in the north to the Indian Ocean in the south, and the interaction between these two regions influences the strait’s oceanographic dynamics, including salinity variability. Large-scale climate phenomena such as the Indian Ocean Dipole (IOD) and the Madden–Julian Oscillation (MJO) play important roles in modulating salinity in these waters. This study aims to analyze the correlation between salinity and both the IOD and MJO in the northern and southern parts of the Bali Strait, using data from 1999 to 2023. Descriptive statistical methods and Fast Fourier Transform (FFT) analyses were employed. The results show that in the northern waters, the direct correlation between salinity and the IOD is generally weak, with the highest value of 0.22794 at a depth of 1.54 m. Correlations with the MJO are also weak and predominantly negative. In contrast, the southern waters exhibit stronger correlations, particularly between salinity and the IOD, with the highest correlation of 0.29537 at a depth of 25.21 m. FFT analysis further supports these findings, indicating that the IOD exerts a more dominant influence on salinity variability than the MJO, especially at shallow depths. Overall, the IOD has a more significant and consistent impact on salinity variability in the Bali Strait, particularly in the southern region, while the influence of the MJO remains relatively weak.

Abstract

Intensive shrimp aquaculture has grown rapidly in recent years, requiring efficient pond management systems to ensure sustainability and productivity. This study aimed to evaluate the cultivation performance of Litopenaeus vannamei (vannamei shrimp) in High-Density Polyethylene (HDPE) round ponds at a shrimp aquaculture facility in Prigi, East Java, Indonesia. Two ponds (BO1 and BO2) were observed through various cultivation phases, including pond and media preparation, feed and water quality management, growth monitoring, harvesting, disease prevention, and waste treatment. The ad libitum and blind feeding methods were used without feeding rate calculations, and water quality parameters were monitored regularly. Results showed that pond BO1 performed well with a survival rate of 72.69%, an FCR of 1.37, and steady growth (ABW and ADG), indicating effective management. In contrast, pond BO2 experienced significant mortality and poor growth due to early stress from excessive water current caused by oversized paddlewheels, resulting in a survival rate of only 6.95% and an FCR of 4.41. Waste management was conducted using a sedimentation-based Wastewater Treatment Plant (WWTP) without the use of chemicals. These findings highlight the critical role of mechanical suitability and integrated management practices in ensuring successful shrimp cultivation in intensive systems.

Abstract

Hybrid grouper (Epinephelus fuscoguttatus × E. lanceolatus) is a high-value marine fish with significant economic potential in both domestic and export markets. Effective nursery and grow-out management is essential to optimize growth, survival, and overall productivity. This study aimed to evaluate the optimal application of nursery and grow-out techniques for hybrid grouper in concrete ponds at the Marine Aquaculture Installation (IBL) Boncong, Tuban, East Java, Indonesia. The research was conducted over 13 weeks (February–May 2025) using a descriptive approach through direct observation, interviews, active participation, and documentation. Nursery activities included pond preparation, fry selection, acclimatization, size grading, feeding management, and water quality monitoring, while the grow-out phase involved feed management and health maintenance in floating net cages. Results showed an average Specific Growth Rate (SGR) of 6.4% per day and a final survival rate (SR) of 86.25%, meeting the Indonesian National Standard (SNI) minimum requirement of 80%. Effective feeding and optimal water quality contributed to high growth performance and fish survival. These findings indicate that proper nursery and grow-out management is crucial for productive and profitable hybrid grouper aquaculture.

Abstract

Marine pollution from ship waste poses a significant threat to global and national ecosystems, particularly in Indonesia, the world’s largest archipelagic country with 5.8 million km² of waters. This study examines the preparedness of officers at the Tanjung Perak Harbormaster and Port Authority Office (KSOP) in preventing and managing ship waste according to MARPOL 73/78 Annex V, using a mixed-methods descriptive qualitative-quantitative approach. Data were collected through semi-structured interviews, participant observation, document studies, and surveys of 20 officers with at least two years of experience. Validity and reliability were confirmed via Content Validity Ratio (CVR) and Cronbach’s Alpha (α = 0.82). Preparedness was assessed across four dimensions, i.e., regulatory knowledge, information systems & early warning, operational response, and mobilization & equipment, yielding an overall score of 75.27% (“Ready”). Officers’ strengths were in operational response (82.5%) and equipment mobilization (83.6%), supported by 100% participation in Garbage Spill Drill simulations and boom/skimmer availability up to 95%. Weaknesses included regulatory knowledge (67.2%), particularly technical aspects of food waste management (accuracy 60–65%), and information systems (67.8%), with InaPortNet integration only 60%, reflecting global systemic deficiencies (e.g., 22.07% of MARPOL violations). Case studies of KM Sinabung, KM Dharma Ferry V, and KM Dharma Kencana V inspections showed compliance potential via Garbage Management Plans but were limited by inadequate inter-agency coordination and reception facilities (35%). The study recommends intensive training, cross-sector collaboration with Pelindo and waste contractors, and investment in digital technologies, including full InaPortNet integration and AI-based early warning systems, to achieve “Very Ready” status (≥80%). Periodic post-intervention evaluations and econometric impact analyses are also advised to optimize ship waste pollution prevention, support maritime sustainability, and advance SDG 14 on life below water.

Abstract

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.
