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

One of the fishing gear widely used by fisherman in Banten Bay is bottom mini trawl which called jaring arad. The main problem in “jaring arad” fisheries is high bycatch and low selectivity of fishing gear. One effort to reduce high bycatch at jaring arad is the implementation of Turtle Excluder Device (TED. Accordingly, this study aimed to examine community perceptions of the Turtle Excluder Device (TED). Data were collected through interviews with 25 respondents, and the findings were subsequently analyzed using descriptive statistical methods. Research results indicate that 67% of fishermen disagree with the prohibition of jaring arad. However, one of the obstacles to use Turtle Excluder Device (TED) is the limited knowledge and understanding fishers have of the technology. Based on the interview results using the questionnaire, it was found that 61% of the fisherman who participated in the outreach activity had never heard of the TED device, while only 39% had heard of it.  After receiving an explanation during the outreach activity about the use of TED, the majority of participating fishers were willing to try it. Based on the survey, 82% of the fishermen were willing to try the Turtle Excluder Device (TED). Key words: bycatch, jaring arad, selectivity, Turtle Excluder Device
