Frequent Reason

This study aims to determine the level of compliance of fishing vessels operations to Malaysian Fisheries Department rules and regulations as well as to identify the reasons of non-compliance among fishermen in Pangkor Island, Perak. The data was collected through the distribution of questionnaire and analysed using descriptive statistical tools. The level of compliance of fishing vessel operations was determined by a five point Likert scale, whilst qualitative statements were grouped into several topics using qualitative content analysis. The reasons for the fishermen’s non-compliance were also identified by using closed-ended and open-ended questions. The outcome of this study can be categorised into several levels of compliance. As for the reasons for non-compliance, the most frequent reason chosen by respondents was lack of trust towards the authorities.

Traditional Fishing

Utilization of radar satellite data to monitoring vessels distribution in regard to combating IUU fishing is a newly developed in Indonesia. Ship detection using radar satellite data performed with high accuracy which is about 79% to the size of the boats between 24-81 meters (averaging 45 meters).  However, information about accuracy of the radar satellites to detect small traditional fishing vessel are not yet widely available, and making this study is very important to conducted.    The research was conducted at the west part of Belitung Island waters using RADARSAT-2 satellite data to detect vessels distribution which was acquired by radar ground station Perancak at October 25, 2016 and also using vessel position data which is acquired by using GPS tracker.  There are 10 traditional fishing vessel was used as a sample, in accordance with the availability of GPS tracker.  All vessels are made from wood with the size between 11 to 15 meter and using ‘bubu’ as a primary fishing gear to catch fish.  Accuracy test was done using overlay analysis between vessel distribution information resulted from radar image analysis with the vessel position data coming from the GPS Tracker.  Result showed that the accuracy of radar data on extended high incidence beam mode to detect the distribution of traditional fishing vessels with small size (11-15 meters) is about 30% and over estimate measuring between 7.5 to 8 meters.

Adsorption Desorption

The preparation of activated carbon from wood-based industrys residue is one of the most environmental friendly solutions of transforming negative-valued wastes to valuable materials. Wood sawdust was first chemically activated using potassium hydroxide, KOH and characterized by nitrogen adsorption-desorption isotherms measured in Micrometrices ASAP 2020 and Field Emission Scanning Electron Microscope (FESEM). By manipulating three different parameters, the optimal activation conditions were found at temperature of 500°C, activation time of 60 min and impregnation ratio of 1:3. Results showed that the BET surface area, total pore volume and diameter of activated carbon were 1876.16 m2g-1, 0.88 cm3g-1and 6.93 nm, respectively. Nitrogen adsorption desorption isotherm analysis proved the existence of mesopores in activated carbon produced, suggesting that it can be effectively used as an adsorption material.
