Abstract

Abstrak Bank Sampah Hijau Lestari adalah tempat pengolahan limbah plastik pusat yang ada di kota Bandung. Ada beberapa tahap dalam pengolahan limbah di bank sampah ini, mulai dari pemilahan, pencacahan, pencucian dan pemindahan ke dalam karung, pengeringan. Namun, pada proses pencucian dan pemindahan potongan plastik masih dilakukan secara manual. Setelah dilakukan analisis RULA, REBA, dan RWL didapatkan skor yang sangat tinggi yang dapat menyebabkan resiko Musculoskeletal Disorders (MSDs) sehingga perlu adanya perbaikan postur melaui alat bantu usulan. Perancangan alat bantu usulan ini menggunakan metode Ergonomic Function Deployment (EFD) yang menerapkan aspek ergonomi yaitu EASNE (Efektif, Aman, Sehat, Nyaman, dan Efisien) sehingga dapat memperbaiki postur operator untuk mengurangi resiko cidera MSDs. Berdasarkan penelitian didapatkan spesifikasi alat bantu usulan terpilih yang dapat memindahkan potongan plastik menggunakan screw conveyor, alat bantu dapat disesuaikan tingginya, memiliki pengunci roda, sehingga didapatkan nilai skor RULA sebesar 3, nilai skor REBA sebesar 4, nilai RWL sebesar 23 kg, dan LI sebesar 0.28 sehingga nilai tersebut dapat mengurangi resiko cidera MSDs pada operator saat melakukan proses pemindahan potongan plastik.

Abstract Bank Sampah Hijau Lestari is a central plastic waste processing facility in the city of Bandung. There are several stages in waste management in this garbage bank, ranging from sorting, crushing, washing and transferring into sacks, drying. However, in the process of washing and transferring pieces of plastic is still done manually. After RULA, REBA, and RWL analysis, very high scores are obtained which can lead to the risk of Musculoskeletal Disorders (MSDs) so that there is a need to improve posture through the proposal aids. The design of this proposed aid uses the Ergonomic Function Deployment (EFD) method that applies the ergonomic aspects of EASNE (Efektif, Aman, Sehat, Nyaman, dan Efisien) so as to improve the operator's posture to reduce the risk of MSDs injuries. Based on the research, it was found that the specifications of the selected auxiliary tool that can move pieces of plastic using a screw conveyor, the tool can be adjusted in height, has wheel lock, so that the RULA score is 3, the REBA score is 4, the RWL value is 23 kg, and the LI is 0.28 so that this value can reduce the risk of MSDs injury to the operator when carrying out the process of transferring pieces of plastic.
