Abstract

Squid jigging fisheries in Indonesia have developed rapidly, leading to a substantial increase in energy consumption due to the growing number of squid jigging units. Traditionally, metal halide (MH) lamps with electrical power ranging from 24 to 30 kW are used as light attractors. This study aimed to design a LED (light-emitting diode) lamp for squid fishing with a light distribution pattern comparable to that of MH lamps and to evaluate its fuel consumption. The research involved the design and construction of an LED-based squid lamp, measurement of light intensity in air, and comparison of fuel consumption between LED and MH lamps under laboratory conditions. Underwater light intensity was measured in the waters of Banten Bay. The electronic system employed components with total LED power of 450 watts. Results showed that the average light intensity of the LED lamp decreased by only 10.57% compared to the MH lamp. The Specific Fuel Consumption (SFC) of MH lamps ranged from 0.00162–0.00176 kg/hp·h, while that of LED lamps ranged from 0.00109–0.00119 kg/hp·h. The LED system achieved a fuel efficiency of 40.54%, indicating a 19.03% improvement compared MH lamps. Further field-scale experiments are required to validate effectiveness in actual squid fishing operations. Key words: intensity, light, measurement, squid

Abstract

Pengudang Village, Bintan Regency, Riau Islands, is a coastal area that hosts seagrass ecosystems with high biodiversity. However, this area is increasingly experiencing degradation pressures due to climate change and anthropogenic activities. The limited public knowledge regarding the condition of seagrass ecosystems has become a major obstacle to community-based conservation efforts in the region. This community service activity aimed to disseminate information on seagrass density mapping results using the Object-Based Image Analysis (OBIA) technology to the coastal community of Pengudang. The mapping was conducted at 59 survey points distributed across the shallow waters of Pengudang Village in October 2025. The results identified seven seagrass species with a total coverage area of 344.26 hectares, of which approximately 92% fell into the high-density category. The dissemination of the mapping results was carried out in December 2025 using an interactive outreach method supported by visual media and infographics, and was evaluated through questionnaires distributed to 10 respondents. The evaluation results showed that all assessment indicators were within a score range of 3.7–4.0, categorized as Very Good, with no respondents expressing disagreement regarding either the material or the implementation of the activity. This activity demonstrates that a dissemination approach based on modern mapping technology, delivered through participatory and contextual methods, is effective in improving public understanding, awareness, and conservation motivation among coastal communities toward seagrass ecosystems.
