Abstract

Abstract One of the main processing cassava into Modified Cassava Flour (mocaf) is slicing . So far, operators still do slicing cassava using manual tools with hand gestures repetitive. Its effect, operators complain of stiffness , pain in the arm muscles and fatigue , frequent breaks so that consequently the operator takes a long time to clice of cassava . Therefore, the authors intend to design a slicer machine wake cassava based anthropometric workers , so that workers can work safely , comfortable , healthy , in accordance with the principles of ergonomics so as to reduce musculoskeletal complaints and save time slicing to be more efficient and effective. Given method is to use a questionnaire measuring musculoskelatal complaint Nordic Body Map ( NBM ) and processing time slicing the operator using a stop watch before and after using the machine slicing of cassava . Then designing wake slicer tool cassava using anthropometric data operator, and the operator ergonomics intervention. The results achieved in this research is the machine slicer of cassava that adjusted for anthropometric data of workers. Scores of workers experienced musculoskeletal complaints was 17.08 before the intervention , after the intervention decreased with score of 2.77. and cassava processing time using a manual perajangan 18 min/kg, after using the machine chopper dropped to 2.12 min/kg . So the chopping time efficiency reaches 803 % . Keywords Cassava Machine slicing, Musculoskeletal, efficiency

Abstract

PT. YZ menghadapi masalah pemborosan dalam proses produksi karet di Departemen Finishing Goods, khususnya pada aktivitas potong sampel dan pengisian peti yang menunjukkan tingkat pemborosan tertinggi. Penelitian ini bertujuan untuk mengidentifikasi dan mengatasi pemborosan tersebut guna meningkatkan efisiensi produksi. Metode Value Stream Mapping (VSM) digunakan untuk memvisualisasikan alur proses produksi secara keseluruhan, sedangkan Failure Mode and Effect Analysis (FMEA) diterapkan untuk mengidentifikasi kegagalan dalam proses produksi dan menentukan prioritas pemborosan terbesar. Hasil analisis menunjukkan bahwa aktivitas potong sampel pada Quality Control memiliki nilai Risk Priority Number (RPN) tertinggi yaitu 240, menandakan kegagalan analisis karet yang serius, biasa terjadi, dan sulit dideteksi. Proses pengisian peti juga memiliki nilai RPN tinggi yaitu sebesar 192, akibat kesalahan penyusunan yang sering terjadi. Rekomendasi perbaikan meliputi peningkatan akurasi pemotongan sampel dari 35 gram menjadi 38 gram, penggunaan timbangan digital berakurasi tinggi, serta pelatihan tambahan untuk karyawan. Penerapan Lean Manufacturing dapat mengurangi pemborosan dalam proses produksi karet di PT YZ, meningkatkan efisiensi, dan kualitas hasil produksi.
