Abstract

PT X is a plastic manufacturer and the company utilizes SAP system in its operations. Unfortunately, there is still an issue regarding deviation of raw material stock between system and actual inventory. Therefore, this research aims to investigate and analyze the measures that can be taken to prevent the occurrence of such deviation in the Production Floor Plastic Injection (PFPI) PT X. To achieve this objective, the DMAIC approach (Define, Measure, Analyze, Improve, Control) is employed as the framework for the research process. Through the creation of a Fishbone Diagram, several root problems were identified, focusing on method-related factors. These problems include the absence of raw material quantity calculations, lingering overwork (mixer -> setter), inadequate control of good issue and good receipt, and the lack of recording for leftover material transfers. To address these issues, proposed improvement suggestions were formulated, including the implementation of "Raw Material Requirement Calculation Form," "Raw Material Work Order Form," "Inbound and Outbound Raw Material Form," "Good Issue and Good Receipt Recording Form," and "Good Issue Request Form." These proposals are believed to aid in improving the calculation, recording, and monitoring systems for raw materials in the Production Floor Plastic Injection (PFPI) PT X.

Abstract

PT X merupakan perusahaan rokok di Indonesia, permasalahan yang terjadi pada perusahaan yaitu terkait penyediaan layanan transportasi yang kurang optimal karena tidak ada support system untuk meningkatkan layanan seperti data layanan belum tercatat secara realtime, pembagian tugas driver dan kendaraan yang kurang optimal, dan permasalahan keluhan pengguna karena tidak terpenuhi seluruhnya. Rata-rata permintaan yang tidak terpenuhi selama Bulan Juni-Desember 2022 sebesar 2,54% sedangkan harapan perusahaan adalah memenuhi seluruh permintaan. Metode yang digunakan untuk menyelesaikan masalah adalah Metode DMAIC beserta beberapa tools seperti SMART Target, 5 Why Analysis, dan RACI Matrix. Upaya untuk menangani permasalahan tidak ada support system adalah dengan menganalisis business process awal dan membuat kerangka sistem TOSS (Transport Support System) untuk menunjang layanan transportasi. Upaya untuk mengatasi keluhan pengguna adalah dengan menggunakan 5 Why Analysis dan melakukan kerja sama dengan pihak eksternal penyedia layanan transportasi. Implementasi kerja tersebut diterapkan selama dua bulan dan berdampak baik yaitu rata-rata permintaan yang tidak terpenuhi menurun menjadi 0,47%. Pengontrolan hasil perbaikan adalah dengan mengikuti rancangan langkah kerja sistem dan penggunaan RACI Matrix.

Abstract

PT X is a cigarette company in Indonesia, the problems that occur with the company are related to theprovision of transportation services that are less than optimal because there is no support system toimprove services such as service data has not been recorded real time, division of tasks driver and vehiclesthat are less than optimal, and problems with user complaints because they are not fully met. The averageunfulfilled demand during June-December 2022 is 2.54%, while the company's hope is to fulfil allrequests. The method used to solve the problem is the DMAIC Method along with several tools likeSMART Target, 5 Why Analysis, and RACI Matrix. There are no efforts to deal with the problem supportsystem is to analyze business process early and create a TOSS system framework (Transport SupportSystem) to support transportation services. The effort to overcome user complaints is to use 5Why Analysisand cooperate with external transportation service providers. The implementation of the work was carriedout for two months and had a good impact, namely the average unfulfilled demand decreased to 0.47%.Controlling the results of repairs is by following the system work step design and using the RACI Matrix.
