Abstract

Fiber Reinforced Plastic (FRP) material has been widely used as a ship construction alternative to wood. FRP has many advantages such as lightweight material, easy maintenance, weather resistance, economical price, and shorter production time. FRP ship production is weak from the waste factor produced, such as production residue during shipbuilding, ship molds, and FRP shipwrecks. FRP waste can impact the environment, economy, and human health. These impacts include soil pollution, microplastics, skin diseases, and human respiratory disorders. FRP material tends to be burned by many shipyards but still leaves waste in the form of dust. FRP material is difficult to decompose and takes a long time to melt. One strategic effort to minimize the impact of FRP is to recycle FRP. This study aims to reduce FRP waste by making composite boards from FRP waste. The method used was experimental, involving the making of 12 specimens and testing the density, MOR, and MOE. Based on the results of the density value test, the average value obtained follows the JIS A 5905-2003 reference. The MOR and MOE values for each specimen do not comply with the Indonesian Classification Bureau (BKI) standards. In the ANOVA test calculation, no significant differences were obtained for MOR and MOE.

Abstract

The escalating utilization of FRP materials ultimately gives rise to issues related to waste production. Waste disposal typically involves incineration, as practiced at UD Wahyu Asih Fiberglass. The combustion process yields thick black smoke and a pungent odor. Incineration does not annihilate fiberglass material but generates combustion byproducts, such as solid ash. This study aims to elucidate the material type, chemical element content, and associated properties inherent in FRP shipbuilding materials at UD Wahyu Asih Fiberglass Shipyard. The methodology commences with the identification of materials utilized in FRP ship manufacture through field observations at the shipyard. Another objective of this study is to quantify the ash content and ascertain the total particulate matter during the incineration process of FRP shipbuilding material waste via laboratory tests. The total particulate data obtained will be compared with applicable emission quality standards.

Abstract

Outrigger boats are prevalent in Indonesian waters. In Indonesia, the majority of Outrigger boats have a gross tonnage of less than 7 GT, resulting in their classification as "boats." After being hit by waves, the outrigger serves as a balancing mechanism on the boat, ensuring that it does not capsize and that it continues to keep its stability. In spite of the fact that they have a number of benefits, outrigger boats also have a number of drawbacks. One of these drawbacks is that they need a mooring space that is sufficiently large to anchor the boat at the beach or pier. This research was carried out through the use of experimental methodologies. The stability value is a reference to the design parameters established by IMO A.749 (18), which are applicable to all boats. Type 2 boats have a maximum GZ value that is greater than that of type 1 boats. According to the findings of the study, the utilization of the Palabuhanratu pool was increased by 33% on model B boats and by 52% on boat C when the outrigger boom was pulled while the boat was in the port pool. This was in comparison to the original value when the boat was anchored without pulling the outrigger boom.
