Abstract

The development of maritime technology drives innovation in ship design, including a 5 GT pilot boat designed for high efficiency and performance in Indonesian waters. This vessel is constructed using Fiberglass-Reinforced Plastic (FRP), a material known for its strength and cost-effectiveness compared to wood. Measuring 12.4 meters in length, the boat is powered by a total of 700 HP from two Yamaha F350UCB V8 5.3L F350 outboard engines, enabling it to reach an optimal speed of approximately 25 knots. Stability and power analysis, conducted using the Maxsurf application, indicate that positioning the engines at the stern on both the right and left sides provides the best stability with an inclination angle of 73.6°. This design is expected to enhance operational efficiency and support pilotage activities in dynamic waters.

Abstract

Betutu (Oxyeleotris marmorata) is a freshwater fish of high economic value widely consumed in Southeast Asia. Overfishing in nature has resulted in a decline in population and genetic diversity. Genetic diversity is an important factor in the long-term survival of O. marmorata populations. This study aimed to analyze the genetic diversity and phylogenetic relationships of O. marmorata in three rivers in East Java (Bengawan Solo River, Kali Tengah River, and Bondoyudo River) using a DNA barcoding approach. Twenty-two fish specimens were collected, identified, and analyzed using PCR and DNA sequencing. The results showed that O. marmorata from the three locations had a low level of genetic variation, with genetic distance differences between 0.00-0.02. Phylogenetic analysis showed that specimens from East Java were closely related to populations from Thailand and Australia. This study emphasizes the importance of genetic conservation and population management with the development of hatcheries to reduce dependence on natural catch.
