Abstract

Lighting is one of the human basic needs that must be fullfiled. Compact fluorescent lamps is the most used lamp as source of lighting. However, they contain mercury, which is classified as heavy metals, that can potentially harm the environment. Even as mercury container, many people didnt know that. Many people dont know the method to handle the broken or used compact fluorescent lamp. They just dispose the broken compact fluorescent lamp to trash without considering the effect of mercury contained.Inverse Manufacturing concept is about designing product life cycle that aims to repair and reuse product components so that the negative impact can be reduced and minimized. In this research, the concept of Inverse Manufacturing is applied on handling the compact fluorescent lamp product in Bandung, West Java. The study is begun with designing the Inverse Manufacturing concept’s model by adding the step of collecting back (two scenarios), sorting, repairing, remanufacturing, and recycling into the life cycle of compact fluorescent lamp. The results of recycling rates of 15 Watt compact fluorescent lamp  (about 234 grams) starts from the lowest value,  and the maximum value are 27,51 % (64,366 grams),  and 27,61 % (64,609 grams). By applying this concept, the result are the reduction on the amount of compact fluorescent lamp waste dumped into the environment and the achievement of  the conservation of natural resources through the reuse of used components.

Abstract

The posture/body position of batik maker is conducted by kneeling on the ground (squatting) especially on the staining activity (smearing) that is placed on the floor. This body position causes the batik maker’s posture or position in doing the static work (motionless) approximately 3 hours per staining. It can cause a fatigue in static muscle load. In order to reduce static muscle load, the researchers tried to design the alternative tool to be a replacement of batik rest. The purpose of this research is to know the reduction level of muskuskeletal complaints, fatigue and how well the increase in productivity after the change of posture/staining position (smearing) on the floor becomes sitting position in a chair-table in Ergonomics. The research method is the similar subject experiment. Batik table design has an adjustable height and tilt and also can be rotated so that It facilitates the process of coloring (smearing). The Application of Ergonomics in Designing Batik table can show the reduction level of musculoskeletal complaints in batik coloring (smearing) up to 36.63%, the fatigue decrease around 16.73% and the increase of productivity around 68.18%. It indicates that the improvement of squatting position into a sitting position using a chair-table can reduce the complaints of the musculoskeletal system, fatigue and increase the productivity of batik worker.
