Abstract

The research was conducted in June 2013 in Rupat Starait waters with the aim to deter-mine the constituent materials in the sediment. The Eckman Grab was used to take samples and than the sediment was analyzed to determine the composition and content of organic mat-ter. The results showed that the composition of the sediment composed of lithogenous and biogenous. Lithogenous composition especially in waters and rocks dominating presence even-ly at each station. The highest composition found in a location close to the mainland and one of the areas that get the first time the influence of the tide, from the Strait of Malacca and the flow from Strait of Bengkalis. Lithogenous lowest percentage was found in areas close to the mangrove area whre the station had high composition of litter biogenous. While the station containing the lowest organic matter was the station near the strait of Malacca. Mean while the station closed masjid river and Dumai river containing organic matter was high due to the flow of the river carrying a high content of organic materials.

Abstract

Base on the survei and field visiting at the location of dockyard industry, thestate of traditional dockyard management and technology reported. Traditionaldockyards use wood as raw materials for building mostly small fishing boat of less than5 GT. The location of dockyard is built open on the bank of riverside in the coastal areawithout any covered building. Facilities in the traditional dockyard as well asinfrastructure ro the location are almost nothing deliberately built. The dockyardpersists on the wetland environment, swampy area, and unhealthy working condition.The management of the dockyard is family wise as it belongs to the one core family, butthe boat craft man mostly recruite from extended family. While the technology usedmostly come from the long experiences working in the famili or other dockyard. Themain problem of the traditional dockyard is the raw wood materials are scarce anddifficult to get it, except by high price, whilst capital to secure materials stockunavailable. The consequence, five of seven traditional dockyard surveied have beenstopping to product a new boat; and frustrating to pace the future. The probableeffective idea of way out to the situation is to use alternative wooden materialsubstitution such as FRP.
