Abstract

The starter system is a vital component in the main engine starting process on a ship, so its reliability is an important factor in ensuring smooth sailing operations. This study aims to analyze the effectiveness of implementing preventive maintenance in improving the performance of the main engine starter system on a passenger ship. The study was conducted on the XYZ ship using a descriptive method through direct observation and interviews with the engineer officer. Data obtained included the physical condition of the battery, cable path, solenoid, and internal components of the starter dynamo, then analyzed based on performance parameters before and after preventive maintenance. The results showed several major problems, including heavy starter rotation, rapid battery voltage drop, loose cable connections, and damage to the solenoid. After implementing preventive maintenance such as adding battery water, cleaning terminals, tightening cable connections, and internal maintenance of the starter, there was a significant increase in engine starting speed, battery voltage stability, and starter response. The frequency of previously frequent problems also decreased drastically. The conclusion of this study is that preventive maintenance is proven to be effective in improving starter system performance, reducing the risk of starting failure, and supporting the smooth and safe operation of the ship as a whole. Implementation of scheduled preventive maintenance is recommended to ensure long-term reliability of the starter system.

Abstract

Energy efficiency in small-scale fishing boats has become a critical issue due to their high dependence on fossil fuels, rising operational costs, and environmental impacts. Fishing boats less than 5 GT generally operate with fluctuating engine loads, potentially reducing energy conversion performance. This study aims to analyze the energy conversion efficiency of fishing boats operating in Bali Province. The research method uses a descriptive-quantitative approach through field studies. Primary data were obtained from measurements of fuel consumption, engine power and speed, electrical load, and operating duration at each stage of the boat's activities, while secondary data came from technical documents and operational logbooks. Efficiency analysis was conducted by comparing the input energy from diesel fuel and the output energy in the form of mechanical and electrical energy. The results show that energy consumption is dominated by the propulsion system, especially during the cruising phase. The total energy conversion efficiency is still relatively low, ranging from 22%–30%, and decreases during the maneuvering and fishing phases due to partial engine loads. These findings suggest that improvements in operational efficiency and engine maintenance are needed to reduce fuel consumption, reduce operational costs, and support the aspirations of small-scale fishing.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) dominates global aquaculture production due to its adaptability to intensive systems. However, intensive systems often experience excess accumulation of nitrogenous waste and total organic matter (TOM), which can destabilize microbial communities and affect water quality. While protozoa are known as bioindicators, few studies have explored how their functional composition interacts with nitrogen cycling and production performance in shrimp ponds. This study investigated the relationships between nitrogenous compounds, TOM, bacterial and protozoan abundance in two intensive shrimp ponds (HP: high protozoan abundance and LP: low protozoan abundance). Water quality parameters, including Total Ammonia Nitrogen (TAN), nitrite, nitrate, TOM, and phosphate, were monitored weekly alongside microbial assessments of total bacterial count (TBC), total Vibrio count (TVC), and protozoa abundance. Protozoa were identified microscopically, while shrimp performance was measured by growth, feed conversion ratio (FCR), survival, and productivity. TOM emerged as the primary ecological driver, significantly correlating with Vibrio abundance (r = 0.585, p < 0.05). Although the high-protozoa pond featured greater bacterial biomass and more bacterivorous taxa (e.g., Ciliata, Vorticella), it had lower shrimp productivity. Conversely, the low-protozoa pond dominated by detritivores (Euplotes, Strombidionopsis) achieved superior growth, FCR, and final biomass, despite higher TOM and nitrite levels. These findings suggest that protozoan functional composition, rather than total abundance, critically influences nutrient cycling, microbial stability, and production outcomes. Managing TOM and fostering beneficial microbial loops are essential strategies for sustainable shrimp farming.

Abstract

Sentra Pengolahan Ikan Kusamba merupakan pusat industri pemindangan tradisional yang berperan penting dalam perekonomian masyarakat pesisir Kabupaten Klungkung. Namun, proses produksinya masih memiliki berbagai potensi risiko Keselamatan dan Kesehatan Kerja (K3), terutama akibat paparan panas, penggunaan peralatan konvensional, serta kondisi kerja yang belum ergonomis. Penelitian ini bertujuan mengidentifikasi sumber bahaya, menilai tingkat risiko kerja, dan menentukan upaya pengendalian menggunakan metode Hazard Identification, Risk Assessment, and Determining Control (HIRADC). Penelitian dilakukan secara deskriptif kuantitatif melalui observasi, wawancara, dan kuesioner kepada 15 pekerja pada setiap tahapan produksi. Hasil penelitian menunjukkan bahwa tahap perebusan memiliki risiko tertinggi (84,42%), diikuti penyiangan (74,03%), sementara pengemasan dan pendinginan tergolong risiko rendah. Sebanyak 73,3% pekerja telah menggunakan APD, namun kepatuhan dan ketersediaannya masih perlu ditingkatkan. Faktor risiko dominan meliputi lingkungan kerja panas dan lembap (60%), keterbatasan APD (26,67%), kerusakan peralatan (20%), serta tata letak kerja yang kurang aman (26,67%). Meskipun seluruh pekerja telah mengikuti pelatihan K3, penerapannya masih bersifat individual. Oleh karena itu, diperlukan penguatan sistem K3 melalui penyusunan SOP, peningkatan APD, pengawasan rutin, serta perbaikan fasilitas kerja untuk mendukung keselamatan, produktivitas, dan keberlanjutan industri.

Abstract

Electrical energy consumption in aeration systems represents a major component of operational costs, primarily due to the low power factor of inductive equipment such as blowers. This study evaluates the effectiveness of capacitor banks in improving energy efficiency and their economic feasibility in small- to medium-scale aquaculture aeration systems. Over 90 days, measurements were conducted on energy consumption, current, voltage, and water quality parameters, including dissolved oxygen (DO) and pH in two systems: without and with capacitor banks. The results showed that the use of capacitor banks reduced daily energy consumption from 15.01 ± 0.45 kWh to 13.13 ± 0.45 kWh (savings of 12.51%), equivalent to approximately 56.4 kWh per month or 686.2 kWh per year. The average current decreased from 2.44 A to 1.88 A, while voltage, DO (6.50-6.64 mg/L), and pH (7.20-7.25) remained stable within the optimal range. Economic analysis revealed that an initial investment of IDR 1,500,000 has a payback period of 18 months, a net present value (NPV) of IDR 2.15-2.33 million (at 8% discount rate), and an internal rate of return (IRR) exceeding 50% per year. These findings demonstrate that the application of capacitor banks not only enhances energy efficiency and reduces power losses but is also highly feasible and profitable for practical adoption in aquaculture operations.

Abstract

Cold storage plays a crucial role in preserving temperature-sensitive products, particularly in the fisheries and food sectors. However, its operation is highly energy-intensive and often constrained by unstable electricity supply in many Indonesian regions. This study quantitatively evaluates a hybrid renewable energy system integrating photovoltaic (PV) panels, diesel generators, batteries, and the utility grid to ensure sustainable cold storage operations. Using measured load profiles, solar irradiation data, and annual operating costs, the system achieved a 60% reduction in diesel fuel consumption, 30-50% lower CO₂ emissions, and annual savings exceeding IDR 100 million compared to conventional generator-based systems. The system demonstrated 83.5% overall efficiency, with a payback period of 4.4 years and a positive net present value (NPV), confirming its economic viability. The novelty of this research lies in presenting the first comprehensive techno-economic analysis of a PV-diesel-battery-grid hybrid system specifically designed for fisheries-based cold storage facilities in Indonesia, considering local solar potential and grid reliability. Despite its feasibility, implementation challenges remain, including a lack of skilled technicians, limited financial incentives, and bureaucratic constraints. To overcome this, the study recommends PV subsidies, low-interest green loans, and public–private partnerships aligned with Indonesia's energy transition roadmap and cold chain development goals.
