Abstract

The problems faced by this shipyard were the insufficient land to increase the ship production, and theinsufficient number of workers so that it took a long time to produce one ship which resulted in piling upof the ship orders at this shipyard. Moreover, it was difficult to obtain the license to export the shipsabroad. This study was conducted from June 20th to July 4th. This study was located at the Shipyard ofthe New Bagansiapiapi Harbor, Rokan Hilir Regency, Riau Province. The data obtained were analyzed byusing a descriptive analysis and to know the development the data were analyzed by using SWOTanalysis. This shipyard had low technology and was managed by using a family management system.Based on the SWOT analysis carried out by the New Harbor Shipyard, it can still be developed because itwas in a 1.01 quadrant. The strategic plans for the development of the shipyard of the new Harbor wereholding a training for the timber shipbuilders to build FRP ships, attending an entrepreneurship training inthe management of the shipyard industry for shipyard owners, and collaborating with stakeholders such asthe government, raw material supply companies, training and education fields (college) to be able todevelop the New Harbor Shipyard.

Abstract

Pulp and paper industry is one of industry that is relatively much generate solid waste, oneof is the solid waste from the Waste Water Treatment Plant with activated sludge systems,known as biosludge. Biosludge output from the secondary clarifier portion is returned to theprimary clarifier and partly in landfills. Present day this untapped biosludge waste properly,potentially causing pollution as they contain chemicals and hazardous, cause odor and landhoarding unproductive. Present day pulp and paper industries generate solid waste(biosludge) among 3-4 % of the production capacity. In this research has been done the testof Toxcicity Characteristic Leaching Procedure (TCLP). Method TCLP analysis performed isa method of Glass JAR USEPA SW-846 Method 1311. TCLP analysis results for each ofthese metals concentrations in unit mg per liter samples are: arsenic (0.004), barium(0.122), boron (2.66), cadmium (0.011), chromium (0.003), copper (0.025), copper (0.051),mercury (0.0003), selenium (<0.001), silver (<0.001), zinc (0.084). TCLP concentrationswere below the TCLP standards contained in Regulation No. 18 and 85/1999. According tothe delisting hierarchy non hazardous and toxic waste by regulation number 85/1999, wastebiosludge pulp and paper categorized as non hazardous and toxic waste. Althoughcategorized as non hazardous and toxic waste, destruction of the future scenario will come tobe a concern. Given the heavy metals in the environment are not easily degraded and eventends to accumulate in the food chain through biomagnification. It can be harmful to humanhealth, the survival of other creatures and can cause damage to the ecosystem.

Abstract

This study analyzes the greenhouse gas estimation calculation for CO 2 and NO x (asNO 2 ) emissions. Estimation is calculated using the SANGEA application which is basedon the fuel gas consumption and composition for the combustion engine. The estimationcalculations are then compared with the results of on a direct measurement by using acontinuous emission monitoring system (CEMS.) Furthermore, the estimationcalculation is referred to some related regulations to see if it meets with the standard, toknow the quality levels or “tier” and reliability of the SANGEA application used, alsoto learn more on the strategy undertaken by emitters in managing GHG emissions. Thestudy methodology used is descriptive qualitative analysis by performing field survey tolearn how to perform direct measurements with continuous emission monitoringequipment or CEMS in place (in situ) and how to calculate estimation emissions usingthe SANGEA applications for the operation of combustion engines or turbines. Theresult of this study shows that there are differences result between the SANGEAcalculation and CEMS direct measurement, where the SANGEA calculation result is19.7 - 27.8% lower than the direct measurement and this difference result is still closewith the previous studies that have been done, 18.3 to 30.7%, which is becomes atheoretical reference for this comparison calculation and direct measurement study.
