Abstract

Sutindo Raya Mulia is a stockist company that purchases, stores, and resells it to consumers. PT Sutindo Raya Mulia is headquartered in the city of Surabaya and has branch offices in Jakarta, Semarang, Balikpapan, and Samarinda. One of the products offered by SRM is a stainless steel plate. Plate products have 3 series (S200, S300, and S400) and have different suppliers consisting of both local and international. Some of the weaknesses of the purchasing process can be caused by the selection of suppliers that are not fixed when purchasing products from suppliers. This is because the company does not have priority criteria in selecting suppliers. Priority criteria are determined using the Analytical Hierarchy Process method. Supplier assessment is determined using the Technique for Order Preference by Similarity to Ideal Solution method. The results of the AHP method obtained the weight and order of these criteria, price (0.261), availability (0.206), quality (0.200), position (0.106), quantity (0.102), MOQ (0.060), delivery (0.038), payment method (0.027). The results of the TOPSIS method obtained the value and sequence of suppliers, AB (0,587 - 21,0%); AC (0,764 - 27,3%); AD (0,565 - 20,2%); AE (0,490 - 17,5%); AF (0,397 - 14,1%).

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

PT X is a manufacturing company operating in the integrated cardboard industry, utilizing various machines, including flexography machines. This study aims to analyze the primary causes of production deficiencies in the flexography process and provide improvement recommendations using the Six Big Losses-based Overall Equipment Effectiveness (OEE) method. The OEE analysis revealed that the average availability ratio is 88.8%, falling short of the world-class standard of 90%. A deeper analysis using the Six Big Losses methodology identified that the primary cause for not achieving the desired availability ratio is the high percentage of setup and adjustment losses, which stands at 7%. To address these issues, several recommendations are proposed. Firstly, conducting comprehensive training for operators on the proper and correct operation of flexography machines is essential. This training will enhance their technical skills and reduce the time lost during setup and adjustments. Secondly, implementing daily briefings for operators before shifts begin, coupled with regular supervision, will ensure consistent adherence to operational standards. Moreover, establishing a routine and time-limited cleaning schedule for machines and work locations will minimize unexpected downtimes due to maintenance issues. Finally, developing and enforcing standardized machine operation protocols will promote discipline among operators, ensuring that all procedures are followed meticulously. These recommendations aim to improve the overall efficiency of flexography machines, thereby increasing the availability ratio to meet or exceed the world-class standard. By addressing the root causes of production inefficiencies, PT X can enhance its operational performance and maintain its competitive edge in the cardboard industry.

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.
