Abstract

PT Torabika Eka Semesta is a company producing healthy drinks and food. The existence of factories and various products certainly requires effectiveness and efficiency at work. The productivity level in the company is quite good, as seen from the achievement of the output target from January to December 2023 above 80%. The achievement of the output target can be caused by several things, such as off-production machines, delays in starting production, and output fluctuations. The purpose of doing productivity analysis is to discover the problems that affect productivity. The productivity analysis uses three methods: the Objective Matrix (OMAX), the Fault Tree Analysis (FTA), and the Analytical Hierarchy Process (AHP). The OMAX method is designed to calculate productivity values. The FTA method is used to identify how a problem can occur at the highest level in a system. The AHP method is used to calculate the weighting of each indicator. The results of the AHP method obtained values of 0.1888, 0.4121, 0.1252, 0.1728, 0.1011 for indicator 1 to indicator 5 respectively. Then, using the OMAX method, the productivity values of 1.640, 1.415, 6.665, 5.548, 2.371, 1.716, 2.227, 2.470, 2.089, 1.387, 1.591, 1.396 were obtained from January 2022 to January 2023. Based on the calculation results, it is known that defect/rework output, machine stop time and late start of production are indicators that have deficient performance. Implementation was performed by attaching a "Cello Replacement Instructions" sticker to the machine. The implementation results showed an increase in productivity value in January by 1.613.

Abstract

The Interior Department is one of the departments of PT X that produces bus and minibus interior parts. During the interior production process there are still quite a lot of defective products. There are six types of defects, namely air bubbles, not 100% printed, double tip insulation does not stick, torn, too dense/less dense, and color striped. The main focus of this research is to analyze the causes of failure of a process and make recommendations for improvements that can be made using the Fault Tree Analysis (FTA) method. From the FTA, improvements are needed to reduce defects in the Interior Department. Recommendations for improvement that can be given to the company are to create a checklist form to make it easier for operators to clean the mattress regularly, to check that the non-stick liquid has been sprayed twice, to ensure that the mattress has been heated every morning, to ensure that the paint has been shaken before use so that there are no striped colors, and to ensure that the paint has been sprayed twice. Then the next improvement recommendations are to provide and attach a standard description to each injection number on each product, make a machine maintenance schedule, replace the non-stick liquid with an old model that is not too strong, provide a timer on the mattress that is used as a reminder when waiting for the paint to dry, procure a mattress equipped with a sound sensor, and procure a generator.

Abstract

The study focuses on the Supporting department, responsible for producing components for assembling minibuses, including the J type. The department faces several issues, including a 60% confusion rate in component names out of the 600 components, delays and errors in component delivery spanning 4 to 16 hours, and the absence of a Standard Operating Procedure (SOP). Addressing these challenges necessitates the development of a material order system, tackled using the System Development Life Cycle (SDLC). Through SDLC analysis, solutions were derived, involving the creation of system programs, enhancing system flow, standardizing component names, grouping components into kits, establishing component catalogs, and formulating SOPs. This comprehensive solution was implemented at PTXYZ. The outcomes revealed significant improvements: standardization of component names among operators, administrators, and Microsoft GP, where 600 raw components were grouped into 98 packages, reducing delays to less than one working hour, meeting production schedules without delivery errors, and successful implementation of SOPs and catalogs facilitating the production process. Continuous monitoring is crucial to prevent the recurrence of delivery delays and name confusion.

Abstract

PT Wijaya Karya Industri dan Konstruksi has businesses in the fields of Steel, Plastic, Pressing and Casting (PPC) Manufacturing and heavy construction equipment. The PPC factory produces various kinds of manufacturing components, one of which is vehicle spare parts made from metal which are produced using a casting process. One of the products produced using a casting process is Pipe Water Inlet EW010. There are many Pipes Water Inlet EW010 defective products with an average of 52% defective products in July-August 2023. The research was conducted to analyze the sigma value and determine the factors of product defects and the impact of the defects to provide suggestions for product quality improvement. In this research, the method applied is the Six Sigma method and FMEA, by implementing DMAIC (Define, Measure, Analyze, and Control). From this research, the results showed that the most common defects were Leaking, Pen/core, and Porous, namely 89% cumulative. Pipe Water Inlet EW010 products are currently at level 2.44 sigma so corrective action needs to be taken to reach the six-sigma level. By applying the FMEA method, it can be seen that the most significant and most frequently occurring product defects are caused by poor core quality and work method errors. Therefore, the recommended alternative repair solution is to improve the quality of the cores used and improve work methods. The results show an increase in the sigma level value from 2.44 to 2.86 and a decrease in average defects from 52% to 23%.

Abstract

Quality control is a vital aspect of product manufacturing, ensuring adherence to predefined standards and meeting consumer expectations. This study focuses on quality control within the cigarette production process, specifically in PT PID Ongkowidjojo, a prominent manufacturer located in Malang, Indonesia. Despite meticulous production processes, defects in cigarette sticks persist, leading to waste of resources, time, and potential degradation in product quality. The research employs Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA) to identify, analyze, and propose solutions for defects occurring in the maker machine division. Initial analysis reveals common defects such as glue inadequacy, tears in wrappers, and tobacco density inconsistencies, prompting the need for systematic improvements. Through FMEA and FTA methodologies, root causes of defects are pinpointed, and corrective actions are proposed. Implementation of these measures results in a reduction of Risk Priority Number (RPN) values for major defects, indicating a positive impact on production quality. However, limitations in utilizing gate symbols within FTA are acknowledged, suggesting avenues for future research to optimize analytical techniques. This study contributes to the ongoing discourse on quality control in manufacturing industries, particularly in addressing common defects in cigarette production. By integrating FMEA and FTA methodologies, it offers insights into effective defect mitigation strategies, highlighting the importance of continuous improvement in maintaining product quality and operational efficiency.

Abstract

PT PID Ongkowidjojo, yang lebih dikenal dengan sebutan “Oepet,” adalah perusahaan manufaktur yang telah beroperasi di industri rokok sejak tahun 1946. Kantor pusat perusahaan terletak di Jalan Raya Gadang 22 Kota Malang, Indonesia. Penelitian pada PT PID Ongkowidjojo berfokus pada pengendalian kualitas tembakau pada tahap proses 1 (satu). Tahap ini terjadi pada bagian pertama dari proses produksi tembakau yang berada di gudang work in process. Pengendalian kualitas tembakau ini bertujuan untuk memastikan bahwa rokok yang dihasilkan memenuhi standar rasa dan sensasi yang telah ditetapkan. Metode yang digunakan untuk pengendalian kualitas adalah pengendalian kualitas statistik. Pengumpulan data inspeksi harian dilakukan oleh Quality Control (QC) Inspector pada tahap 1 proses utama. QC Inspector memeriksa berbagai parameter, termasuk kandungan air, ukuran tembakau, kebersihan, aroma, impact, rasa, dan tingkat iritasi dari setiap tobacco finish blend yang telah digiling pada hari tersebut. Hasil pengamatan menunjukkan bahwa maksimal penyimpanan tembakau saosan adalah satu minggu; lebih dari itu, kualitas tembakau mengalami penurunan. Perbedaan antara hasil lapangan dan teori perkuliahan terutama terlihat pada penilaian rencana sampling. Pada bulan Agustus 2023, penilaian rancangan sampling menunjukkan nilai Operating Characteristic Curve (OCC), yang menggambarkan probabilitas kesalahan atau cacat sebesar 1% hingga 5%. Nilai penerimaan dalam hal ini adalah 100%. Selain itu, kurva Average Outgoing Quality Inspection (AOQ) menunjukkan nilai Average Outgoing Quality Level (AOQL) sebesar 0,06, yang berarti peluang menghasilkan kualitas terburuk adalah 6%. Sebagai usulan saran pada PT PID Ongkowidjojo dapat mempertimbangkan peninjauan kembali kualitas atau rencana sampling tembakau saosan yang diproses pada tahap utama, mengantisipasi perubahan cuaca yang dapat mempengaruhi kualitas tembakau saosan, terutama pada suhu tinggi, dan menggunakan alat pengukur kandungan air yang sesuai dengan tembakau saosan.

Abstract

Pada setiap produksi rokok di PT PID Ongkowidjojo, pasti terdapat produk yang tidak lolos uji kualitas. Hal ini disebabkan oleh beberapa faktor salah satunya berat timbang penggunaan tembakau dalam rokok per kotak yang berbeda-beda atau tidak berada pada batasannya. Penelitian ini difokuskan untuk menganalisis berat timbang rokok per kotak dalam kemasan yang sudah siap didistribusikan dengan metode SPC. Metode SPC (Statistical Process Control) dipilih untuk menilai kemampuan proses dan variasi dari data berat timbang rokok SKM dengan menghitung nilai kapabilitas proses (CP dan CPK). Dari hasil pengumpulan data, ditemukan bahwa nilai CP=0,4561 dan CPK=0,12251. Dapat ditarik kesimpulan bahwa kemampuan proses PT PID Ongkowidjojo dalam memenuhi spesifikasi berat timbang rokok kurang baik karena nilai CP dan CPK kurang dari 1. Faktor yang mempengaruhi keterbatasan kemampuan proses antara lain bahan baku material yaitu material yang tidak sesuai dan tekstur serta kelembapan tembakau tidak mencapai standar, faktor manusia yaitu kurangnya pengalaman operator baru dan ketidaktelitian pada proses produksi, faktor mesin seperti kurangnya maintenance mesin dan penggunaan mesin yang sudah tua, dan faktor lingkungan seperti cuaca dan iklim tidak stabil sehingga mempengaruhi suhu dalam ruang produksi dan gudang tembakau. Kemampuan proses pada PT PID Ongkowidjojo bisa ditingkatkan bila berfokus pada perbaikan faktor-faktor yang ikut mempengaruhi proses produksi itu sendiri.

Abstract

This study aims to enhance equipment effectiveness in the primary cigarette manufacturing process at PT. PID Ongkowidjojo, focusing on Stage 3, a critical production phase with significant downtime due to equipment failures. Using Overall Equipment Effectiveness (OEE) and Failure Mode and Effects Analysis (FMEA), the research identified nine key failure modes affecting interconnected machines. Based on these findings, targeted improvements were implemented, including scheduled maintenance, real-time monitoring, periodic cleaning, and spare parts inventory management. As a result, the OEE value increased from 50.52% to 56.57%, driven by improvements in Availability (71.07% to 79.22%) and Quality Rate (92% to 93.36%), despite a slight decline in Performance Rate (77.20% to 76.25%). This study highlights the importance of integrating OEE and FMEA methodologies to reduce downtime and address equipment inefficiencies. By tackling the Six Big Losses, particularly equipment failures, this approach offers actionable insights for maintaining operational efficiency and fostering continuous improvement in manufacturing systems.
