Abstract

Industri Barokah Jaya merupakan industri yang terletak di Desa Turus Gede Rembang. Industri ini memproduksi krupuk rambak. Salah satu proses produksinya adalah pemotongan krupuk yang dilakukan operator dengan posisi duduk di kursi kecil (dingklik) dan krupuk yang akan dipotong diletakkan di lantai. Berdasarkan observasi awal, operator mengalami rasa sakit pada bagian tubuh tertentu. Hal ini mengakibatkan target produksi menjadi tidak optimal. Melihat kondisi kerja tersebut perlu dilakukan perancangan kursi dan meja kerja pada stasiun pemotongan. Untuk merancang fasilitas kerja tersebut digunakan data antropometri tubuh operator di Industri Barokah Jaya, keluhan-keluhan selama bekerja dan waktu proses pemotongan krupuk. Hasil penelitian ini adalah rancangan meja dan kursi kerja pada stasiun pemotongan. Berdasarkan implementasi dihasilkan perbandingan kondisi awal dan akhir sebagai berikut : kondisi sebelum perancangan, waktu baku dan output standar adalah 9,068 detik/unit dan 396 unit/jam. Setelah perancangan, waktu baku dan output standar adalah 7,377 detik/unit dan 468 unit/jam. Terjadi peningkatan produktivitas sebesar 18,18 %.

Abstract

Taylor Spatial Frame (TSF) better known as an external fixation product from several types of fixation devices in the orthopedic field. The Laboratory of Product Planning and Design has manufactured TSF or called OrthoLPPDUNS external fixations. The OrthoLPPDUNS design found that frame instability forming ring-strut angles caused by strut screw rotations was feeling rough due to backlash. The purpose is how to redesign an OrthoLPPDUNS with a Function Analysis System Technique (FAST). FAST method is applied at each stage of starting from the information stage to the interpretation of the results. The OrthoLPPDUNS design with the joint system uses custom components that cause weakness in frame stability. The use of standard components in joint systems can provide solutions to external fixations, although there are still weaknesses in the ring-strut angle. The OrthoLPPDUNS redesign has a better success rate in terms of stability parameters, allowing more precise bone reconstruction.

Abstract

This project is conducted in Company X, a passenger cars wheel producing company located in Sunter, North Jakarta. With a view of increasing the productivity of the company, the focus of this project will be redesigned the layout of the factory. The main problem encountered is that the goods are not produced in single location, causing a considerable hindrance in terms of time and distance, and hence efficiency. The redesigning layout process will use SLP method and flow analysis while supported by analysis of assembly line balancing to optimize the layout. Regarding the evaluation process, ARENA software will be used to simulate and identify the bottleneck in the production process, and comparing the layout alternatives to decide the best layout. The best chosen layout according to the simulation and SLP method that supported with flow analysis and assembly line balancing will be used as the master draft layout that will be proposed to Company X.
