Leaf trolys have been utilized in PTPN VI to transfer tea-leaves between workstations. 75% of operators suffer from manual handling injuries after using leaf trolys mostly on their back and waist. Rapid Upper Limb Assessment (RULA) method is utilized to analize whether those injuries caused by working posture. The analysis states all working postures not ideal and need to be changed immediately (level 4). Ideal working postures achieved by redesigning of leaf trolys i.e. new handle, hidraulics, changing the wheel size and positition. Compliance of ergonomy principles is evaluated by RULA. The analysis reports all working postures have degraded from level 4 to level 1 or 2. Time evaluation reports mostly working postures have reduced the standard time, especially in tea-leaves transfer activity from leaf trolys to DIBN 1 machine inlet by 62,39%.

Abstractâ€” PT. TIJ is a company that produces women's bags. One of the products with high demand is the bag which is marketed under the selling brand LC. The problem that occurs is the length of production time for making bags caused by the layout of the production floor that is not good. The length of production time for making bags has caused the company to not be able to achieve the output target of LC bag production. It is necessary to evaluate the current production floor layout by simulating using ProModel software to get improvements to the production floor layout design by utilizing Genetic Algorithms and MATLAB assistance. The purpose of this study is to find out the proposed improvements to increase the output of bag production based on the evaluation results of the production floor layout simulation at PT TIJ. The stages of this research began with data collection and evaluation of the layout of the production floor using a checklist sheet and Flow Map of the process of making bags as a basis for designing a simulation model. The initial model simulation results produce a bag production time of 4.32 hours or 259.2 minutes. By using the Genetic Algorithm approach and the help of MATLAB, it is iterated to get a better production floor layout so that it can reduce the production time for making bags. The development of a simulation model scenario with the addition of goods moving equipment in the form of wheeled racks resulted in a production simulation time of 211.2 minutes (a 19% reduction in production time). The proposed layout improvement using the Genetic Algorithm approach with the addition of material handling in the form of 50 wheeled racks resulted in a simulation time of 211.2 minutes resulting in a production output of 1669 bags per day or reaching 83% of the target output for bag production.

Abstractâ€” Due to their aging, refinery facilities face the threat of suffering from incidents and accidents. Even fatal injury may be caused if running without proper maintenance planning. The revitalization project is performed intended to replace, repair, or increase production capacity at an existing refinery. Like other projects in the construction sector, the revitalization project tends to experience the same common flaws in their performance; project delay, cost overrun, scope creeping, operational mishaps, and canceled or stopped. The best time for a project to experience idea development, conduct scope changes, prepare excellent project engineering, etc., is at the Front-end Planning stage. This paper focused on project selection and prioritization at the Front-end Planning. The focus is then zoomed in to the sub-stage of Front-end Planning (initiation, conceptual, and basic engineering design). The aim is to eliminate the infeasible and unpromising projects that cannot meet the requirement. This focus is necessary before more resources are expended, which can ignite catastrophic events in the organization, primarily financial.The literature reviews have been done on the references to develop a comprehensive framework that decomposes the front-end planning into three sub-phases, providing the platform for project selection in each stage with its different focus and objectives. The new framework is proposed emphasizing the gate review and decision gates for those three sub-stages under the Front-end planning phase. The framework also provides the windows of having different selection criteria at each stage; hence the proper criteria will be efficiently used at the right time. Project proposals must go through a prioritization process since the organization's resource is not unlimited. Project proposals would experience the evaluation and selection as an individual project and, at a subsequent level, would be evaluated as part of the project proposals pool where the Project Management Office will prioritize the suitable projects worth execution.

Intisari-PT. XYZ adalah perusahaan farmasi yang menghasilkan produk obat generik. Permintaan produk obat MEF pada PT XYZ belum dapat terpenuhi dikarenakan proses produksi obat MEF yang belum optimal. Penelitian bertujuan melakukan evaluasi meminimasi waste yang terjadi, untuk dapat meningkatkan performansi proses produksi obat MEF. Upaya meminimasi waste menggunakan pendekatan lean manufacturing yang diawali dengan pemetaan current value stream mapping (C-VSM) terhadap kegiatan proses produksi obat MEF. Hasil pemetaan C-VSM menunjukkan 14 kegiatan tidak memberikan nilai tambah (non-value added) terhadap produk dengan 4 jenis pemborosan (waste) yaitu waste waiting, defect, transportation dan over processing. Nilai MLT (manufacturing lead time) dan PCE (process cycle efficiency) pada C-VSM adalah 324506 detik dan 39,13%. Perbaikan yang diusulkan pada waste waiting berupa pelatihan operator setiap bulan, penambahan rak untuk peletakan prosedur pengemasan induk (PPI), penyusunan jadwal dan pembuatan form inspeksi mesin stripping. Usulan perbaikan untuk meminimasi waste defect adalah perancangan alat bantu pembatas foil dan pembuatan form pembersihan sensor nozzle, sedangkan untuk eliminasi waste over processing dilakukan dengan menghilangkan aktivitas rekonsialisasi bon putih. Future VSM yang merupakan proyeksi VSM apabila usulan perbaikan dilakukan, dengan nilai MLT proyeksi sebesar 301716 detik dan PCE proyeksi sebesar 52,4%, didapatkan peningkatan efisiensi proses produksi sebesar 13,3% dan diproyeksikan adanya peningkatan output produksi, namun belum dapat memenuhi permintaan produksi pada periode puncak. Perusahaan disarankan untuk mengevaluasi kembali ketersediaan sumber daya produksi yang dimiliki dalam penentuan target produksi terkait pemenuhan permintaan kebutuhan obat MEF. Abstract— PT. XYZ is a pharmaceutical company that produces generic drug products. The demand for MEF medicinal products at PT. XYZ cannot be fulfilled because the MEF drug production process is not yet optimal. The research aims to evaluate minimizing the waste that occurs, in order to improve the performance of the MEF drug production process. Efforts to minimize waste use a lean manufacturing approach, which begins with mapping current value stream mapping (C-VSM) on MEF drug production process activities. The results of the C-VSM mapping show that 14 activities do not provide added value (non-value added) to products with 4 types of waste, namely waste waiting, defects, transportation and over processing. The MLT (manufacturing lead time) and PCE (process cycle efficiency) values on C-VSM are 324506 seconds and 39.13%. Proposed improvements for waste waiting include monthly operator training, adding shelves for placing main packaging procedure (PPI), preparing schedules and creating stripping machine inspection forms. The proposed improvement to minimize waste defects is to design a foil barrier tool and create a nozzle sensor cleaning form. Meanwhile, eliminating waste over processing is done by eliminating the white bill reconciliation activity. Future VSM is a VSM projection, if the proposed improvements are carried out, the MLT and PCE values are projected to reach 301716 seconds and 52.4%. There has been an increase in production process efficiency by 13.3% and a projected increase in production output, but it is still unable to meet production demand during peak periods. The recommendation for companies is to re-evaluate production targets according to resource availability in an effort to meet demand for MEF drugs.
