ABSTRAK/ABSTRACT

Proses cleaning midsole di PT Hyangdotama Indonesia masih dilakukan secara manual oleh operator, sehingga membutuhkan waktu yang relatif lama, hasil pembersihan kurang konsisten, serta memerlukan tenaga kerja yang cukup banyak. Kondisi tersebut menyebabkan efisiensi proses produksi menjadi rendah dan produktivitas dipengaruhi oleh kemampuan operator. Oleh karena itu, penelitian ini bertujuan untuk merancang dan membangun mesin cleaning midsole yang mampu mengotomatisasi proses pembersihan sehingga dapat meningkatkan efisiensi kerja dan kualitas hasil cleaning. Metode yang digunakan dalam penelitian ini meliputi observasi lapangan, wawancara dengan operator, analisis 5 Whys untuk mengidentifikasi akar permasalahan, serta metode rekayasa dalam proses perancangan. Mesin dirancang menggunakan tiga pasang roll busa sebagai penarik dan pengarah midsole, dua pasang roll sikat sebagai media pembersih, sistem transmisi gear dan rantai yang digerakkan oleh dua motor listrik tiga fasa, serta sistem sirkulasi cairan pembersih secara kontinu menggunakan pompa air. Hasil perancangan menunjukkan bahwa mesin mampu membersihkan empat buah midsole dalam satu siklus selama sekitar 10 detik, dengan kapasitas produksi mencapai sekitar 1440 midsole per jam. Dibandingkan dengan proses manual yang memerlukan tujuh operator dengan kapasitas sekitar 70 midsole per orang per jam, mesin hasil rancangan mampu meningkatkan efisiensi waktu proses, mengurangi kebutuhan tenaga kerja menjadi satu operator, serta menghasilkan proses pembersihan yang lebih konsisten. Dengan demikian, mesin cleaning midsole yang dirancang dapat menjadi solusi untuk meningkatkan efisiensi, produktivitas, dan kualitas proses cleaning pada PT Hyangdotama Indonesia.

The midsole cleaning process at PT Hyangdotama Indonesia is still performed manually by operators, resulting in relatively long processing times, inconsistent cleaning quality, and a high labor requirement. These conditions reduce production efficiency and make productivity highly dependent on operator performance. Therefore, this study aims to design and develop an automatic midsole cleaning machine capable of automating the cleaning process to improve work efficiency and cleaning quality. The research methods employed include field observations, interviews with operators, 5 Whys analysis to identify the root causes of the problem, and engineering design methods for machine development. The machine is designed with three pairs of foam rollers functioning as midsole feeders and guides, two pairs of brush rollers serving as cleaning media, a gear and chain transmission system driven by two three-phase electric motors, and a continuous cleaning fluid circulation system powered by a water pump. The results show that the machine is capable of cleaning four midsoles in a single cycle within approximately 10 seconds, achieving a production capacity of around 1440 midsoles per hour. Compared to the manual process, which requires seven operators with a capacity of approximately 70 midsoles per operator per hour, the proposed machine significantly improves process efficiency, reduces labor requirements to a single operator, and provides more consistent cleaning results. Therefore, the designed midsole cleaning machine can serve as an effective solution to enhance efficiency, productivity, and cleaning quality at PT Hyangdotama Indonesia.
