Abstract

Skipjack tuna (Katsuwonus pelamis) is a large pelagic fish that seeks prey using the sense of sight, so the color of the hook used must be able to attract the attention of skipjack to eat the hook. The purpose of this research is to determine the effect of hook color on pole and line catches. The colors of the hook used are red, green and silver. The analysis used to see differences in skipjack catches based on hook color used two analyzes, namely comparative descriptive and statistical. Comparative descriptive analysis was carried out on the composition of pole and line catches. Statistical test using completely randomized design (CRD). The results showed that the hooks that produced the most skipjack tuna were red with 1785 fish or 57% of the total catch, then green with 830 fish (26%) and silver with 513 (17%) catches. Based on the CRD ANOVA statistical test, the average difference in catches based on hook color was significantly different with a significance value less than 0.05 (0.00<0.05), which means the catches of the 3 hook colors were significantly different. From the catch data, the hook color that gets the most catches is the red hook.

Abstract

This study aims to examine the effect of different concentrations of NaOH (60%, 70%, and 80%) on the isolation process of chitosan from by-products of squid bone (Loligo sp). The resulting chitosan was then tested for water content, solubility, yield, degree of deacetylation, and functional groups. The results showed that the physical appearance of chitosan tends to be white, specific to the characteristics of commercial chitosan. The use of different NaOH concentrations only affects the water content. The water content of chitosan in the 70% and 80% NaOH treatments has met the maximum chitosan quality standard of 12%. The highest chitosan solubility was obtained in the 70% NaOH treatment, namely 97.76%. Likewise, the best degree of chitosan deacetylation reached 95% (70% NaOH treatment), while the average yield of chitosan obtained reached 25.55%. In general, the absorption values of functional groups in the NaOH treatment (60%, 70%, 80%) showed that there were characteristics of chitosan, namely carbonyl (C=O) and amino (N-H2) vibrations in the fingerprint area (~1500–3000 cm-1). and a widening of the absorption band ~1600-3500 cm-1 caused by O-H stretching and N-H vibrations due to deacetylation. Other characteristics are aliphatic C-H vibrations, –NH bond deformation, and glycosidic chitosan (C-O-C) vibrations at a wavelength of ~664–1600 cm-1.

Abstract

Many studies have been conducted on load imbalance in 3-phase electrical installations, but research on the effects of unbalanced electrical loads on 3-phase electrical installations in fishing vessel generators has not been carried out. This study aims to determine the percentage value of load imbalance in the 3-phase electrical installations of KM fishing vessels in Pulau Pinang and observe its effect on the emergence of electric current in the neutral conductor cable in the electrical installation. The Indonesian Classification Bureau (BKI) in Volume IV rules for 2019 and 2022 regarding Electrical Installation on Ships requires that, under normal operating conditions, the percentage value of load imbalance in each phase must not exceed 15%. The research was conducted in three stages: March, April, and June 2021. From the study results, it was found that the average percentage value for load imbalance in KM Pulau Pinang on March 12, was 15.73% with an average electric current value of 8 Amperes in the neutral conductor. On April 7, the average percentage of unbalanced load sharing was 23.42% with an average neutral current of 12.26 Amperes. On June 19, the average percentage of unbalanced load sharing was 16.02% with an average neutral current of 6.11 Amperes.This research can provide new information regarding the study of load sharing imbalance and electric current in 3-phase electrical installations on fishing vessels. It can also serve as an evaluation for ship owners in reducing power losses due to the emergence of electric currents in the neutral conductor.
