A molded expanded polystyrene (EPS) cushion is a flexible, closed-cell foam that can be molded to fit any packing application and is effective at absorbing shock. However, the packaging waste of EPS cushions causes pollution to landfills and the environment. Despite being known to cause pollution, this sustainable packaging actually has the potential to reduce this environmental pollution because of its reusability. Therefore, the objective of this study is to identify the accurate design parameter that can be emphasized in producing a sustainable design of EPS cushion packaging. An experimental method of drop testing and design simulation analysis was conducted. The effectiveness of the design parameters was also verified. Based on the results, there are four main elements that necessitate careful consideration: rib positioning, EPS cushion thickness, package layout, and packing size. These parameter findings make a significant contribution to sustainable design, where these elements were integrated directly to reduce and reuse packaging material. Thus, it has been concluded that 48 percent of the development cost of the cushion was decreased, 25 percent of mold modification time was significantly saved, and 27 percent of carbon dioxide (CO₂) reduction was identified. The findings also aided in the development of productive packaging design, in which these design elements were beneficial to reduce environmental impact. These findings had a significant impact on the manufacturing industry in terms of the economics and time of the molded expanded polystyrene packaging development.

This paper presents a survey on customer needs on wheelchair design for big size patient weight maximum up to 150kg. As more patients who are overweight are admitted to hospitals, critical care nursing care become more important. In order to design new type of wheelchair for big size patient, customer's needs requirements are very important in early development process. It firmly identified with idea age, idea choice, aggressive benchmarking and foundation of item determinations. The data obtained from this survey is very useful for designer in designing of new type wheelchair for big size patient, which currently not available or very difficult to find in the market.

The project present about development lightweight sustainable heat insulation panel from waste material. Scrap tyres and plastic waste was used for this purpose. The fabrication process started with scrap tyres is being cut and blends into smaller pieces. Then, the pieces of the material of rubber from scrap tyres are mixed together with the plastic waste material polyethylene at different composition. The mixture of the materials is pressed together using hydraulic press machine and heat are applied to melt the material in order to create the panel by using the mould. There are few tests that are conducted to the panel to find out its weight, volume and density. In order to determine the most suitable sample among the sample, a test is carried out to each sample. This test involved the black box or wooden box and the container by using the thermocouple and probes to measure the temperature. From the both test using black box and the container, the most suitable sample that excellent in insulating the heat is the sample with the bigger composition of rubber which are sample with 95% of rubber and 5% of polyethylene polymer.

This paper presents an analysis of the mechanism of gears and belt system of Small Sugarcane Juice Extractor machines. The existing design of sugarcane extractor consists of two rollers with the pulley system connected by V-belts. The power generated by the motor will be transmitted from the wheel to the gears and finally the rotating shaft. The rollers will tear then press the sugarcane to extract the juices. The need for the mechanism analysis is necessary to obtain information on existing design for future development of a new version of extractor machine. This is due to currently available sugarcane juice extractors requiring high energy to power bulk and heavy roller mills that are mechanically driven. The analysis is focused on gears, belt and roller as well as the weakness, advantages and disadvantages of the existing extractor.

This paper presents an analysis of the mechanism of Belt-Pulley Driven Spray Plunger Pump. Belts and pulleys are used to transfer kinetic energy from the internal combustion (IC) engine to operate the pump. Combination of pulley and belts was used to transfer motion between each other simply without the need for meshed toothed gearing. The principal remains the same that there is a driver (powered) and driven (free). The benefit from application of belts which are mostly made of synthetic fibres is that no lubrication is necessary compared to chains. The analysis is focused on power transmitted from IC engine to plunger pump (design power) considering service factor as well as determining total number of belts to be used in the system with refer to FENNER Friction Belt Range Brochure Technical Docs.
