Abstract

The degradation in water quality was caused by rapid development and population growth in the absence of a specialize monitoring system and planning methods for river preservation. Sewage, home garbage from commercial and residential sectors, and waste from wet markets and industry are the main causes of pollution. In the action of collecting floating trashes process, the government & non-government from all around the worlds put efforts on inventions, creating machines, crafted the most efficient mechanism to trap all the floating debris in their living area to prevent these trashes from entering the seas .Conventional methods used by Perbadanan Pembangunan Sungai Dan Pantai Melaka (PPSPM) for collection of floating trash are manual by human and trash is transported manually at the collecting center. These methods are risky, costly and time consuming. PPSPM having a demand to make an improvement on existing river cleaning boat by applying conveyor unit on the boat. The study will focus on design improvement and application conveyor unit on the existing river cleaning boat used by PPSPM. This study will also focus on the conveyor type and the analysis on the boat hydrostatics features (buoyancy and stability) using Delftship software. The design of the River Cleaning Boat having a critical issue on the selection of conveyor unit and the buoyant force that acting on the system. The specification of the conveyor unit was identified by calculation on the parameters according to the common conveyor’s data collected and calculations. By considering all the parameters of river surface cleaning systems and eliminating the drawback of the methods used earlier, there have been several mechanisms proposed. DELFTShip software were used to identify the buoyant force of the boat platform for the identification of draft on the conveyor application. The conveyor was designed to be adjustable angle by applying automatic mechanisms (linear actuatuor) so that it could be retracted and cover with metal plates to perform a platform for users to pass through. Based on consultation and research the angle of the conveyor was set as 20° - 30° in order to maintain balance and buoyancy of the boat. Various research methodology is used such as questionnaire with PPSPM, morphological chart method, systematic combination methods and Pugh and Weighted Rating methods. In the nutshell, the design of Malacca Cleaning Boats was studied, the parameters of a conveyor unit were identified, and the best design of collector unit was generated.
