Abstract

Service quality is crucial for companies in the service sector, directly impacting customer satisfaction. PT BLI, a company offering TPS warehouse rental services, is facing issues with a low influx of containers and customer complaints. This research aims to analyze the service quality at PT BLI's warehouse storage section using the Servqual method, which encompasses five quality dimensions and 24 attributes, followed by Importance Performance Analysis (IPA) to identify attributes that require immediate improvement. The Servqual analysis revealed that 10 attributes of PT BLI's service quality do not meet customer expectations. Through IPA, five attributes were identified as high-priority for improvement: the safety of goods in the warehouse (gap of -0.07), the informativeness of employee service regarding activity updates (gap of -0.14), the speed of employees in processing goods in and out of the LCL warehouse (gap of -0.34), the ability of employees to understand consumer needs (gap of -0.01), and the communication skills of employees in providing excellent service (gap of 0.32). Addressing these critical service quality gaps will help PT BLI enhance customer satisfaction, reduce complaints, and potentially increase the number of incoming containers, positively impacting the company's standing in the warehouse rental industry.

Abstract

One of the companies that make tools for printing at one of the printing companies in Jakarta has a product in the form of Offset Roller Printing, where Offset Roller Printing is a mainstay product with the highest sales. The company promises a declining trend in the rejection rate in 2024, with the rejection rate not exceeding 2%. For that, an analysis of the cause of the problem will be carried out until a repair proposal is obtained by using an integrated method which is Statistical Quality Control (SQC) with Failure Mode Effect Analysis (FMEA). Based on the check sheet, it shows the total production in January - December 2023 of 5699. On the overall operational map, there is no point that is outside the upper or lower operational limits. From the results of the FMEA analysis, it can be seen that the highest RPN is the cover for the method factor with the first priority having an RPN value of 252 which means that the vulcanization temperature is not reached or the temperature of the maturity point is not reached. unable to. There is a need to renew the vulcanization recipe so that the rubber matures perfectly and avoids the occurrence of oblong or closed defects. In addition, improvement proposals as a form of evaluation results are given related to the operator's attention factor, operator's skill, various types of materials, working environment temperature, no machine control, comfortable work environment, hostap plastic setting.

Abstract

The coal mining industry is one of the largest contributors to Indonesia’s economy and greenhouse gas emissions at the same time. Indonesian coal mining companies will inevitably expand their business to meet the demand and targets. But Indonesia already set its ambition to become a net-zero country by 2060 or earlier. Without a robust decarbonization strategy at the company level, Indonesia will face difficulties meeting the net-zero target. This study proposes to use one of the Multi-Criteria Decision Analysis, Technique for Order of Preference by Similarity to Ideal, Solution method within the Political, Economic, Social, Technology, Environmental, and Legal criteria to assess five prioritized decarbonization strategies, which are renewable energy, equipment electrification, business shifting, process efficiency, carbon offset. The analysis will evaluate essential sub-criteria such as regulation compliance, investment, social acceptance, technological readiness, and emissions reduction. The data was acquired from a survey of coal mining stakeholders, other journal reviews, and company disclosures. The final results show that process efficiency scores highest on the selected criteria due to high economic and technological value. Meanwhile, other criteria like carbon offset, renewable energy use, and equipment electrification receive lower scores.

Abstract

One of the pivotal aspects of a company lies in its supply chain. The company must effectively and efficiently manage their supply chains to support production quality, achieve organizational goals, and ensure customer satisfaction. This research aims to determine the key performance indicators (KPIs) for the crumb rubber processing industry and provide suggestions for improving its supply chain performance. Supply chain performance measurement was conducted using the Supply Chain Operations Reference (SCOR) model in conjunction with the Analytical Hierarchy Process (AHP) method to determine the weights of the KPIs. The research found that the overall supply chain performance score for the crumb rubber company was 84.92, categorizing it as "Good." However, among the 26 Key Performance Indicators (KPIs) identified, three indicators (i.e. production of defective products, consumer complaints, and returns of defective products) fell into the "Poor" category. Hence, it is crucial for crumb rubber industry stakeholders to address these three criteria to enhance supply chain performance.

Abstract

In the batch process, the company uses the same process facilities to produce various types of products. This allows businesses to change production in response to changes in market demand. Batch processes are widely used in industry. In many cases, batch processes provide several benefits over continuous processes, especially when the industry wants to ensure and maintain the quality standards of its products. This paper proposes a behavioral model of a single-stage batch processing system, using the language of system dynamics. When run, the behavioral model will provide an overview of how the system behaves. The system dynamics language is a formulation of a system of ordinary differential equations that is extracted from the real system being studied, in the form of a stock and flow diagram. The computation of this diagram is further implemented using software. Because it is actually a calculus method, the system dynamics language provides output data much faster than discrete simulation modeling. In this paper, the system behavior modeled is mainly loading, processing and unloading activities. The verification results carried out by testing it on two different case examples show that the model can sufficiently describe the behavior of the conceptual system logically so that the model can enrich experimental tool options related to batch production processes in the future.

Abstract

Oyster mushrooms, Pleurotus ostreatus, are a type of edible wood mushroom. MSME Sidimpuan Hiratake Mushroom have customer, a family restauran. In order to meet consumer demand with quality and quantity requirements, MSME had issues such as inability to fulfill demand due to insufficient production capacity, and occurrence of returns, where both of these continue to increase. Purpose of this study is to explain the process of supply chain, to find out the actual performance, and to provide some suggestions for improvements to the performance of supply chain. The process flows analyzed in this supply chain are product, information and financial. The product produced by partner farmers is fresh oyster mushrooms, the products that will be sent to restaurant are oyster mushrooms that have been weighed, cleaned and packaged. This research method is qualitative and quantitative. The results of analysis with food supply chain network show that the process flow in the supply chain has been going well. The operational performance measurement results were measured using several supply chain operation reference metrics, that the operational performance of the supply chain cannot be said to be perfect overall. To measure marketing performance, the farmer's share value obtained by partner farmers is 58.3% and the marketing margin for MSME is Rp.5.000. The results of 5 why's analysis, inability to fulfill restaurant's demand was caused due to several things including variations in the growth process as well as limited resources of farmers. Returns are caused by differences in quality control standards and qualifications between restaurant and MSME.
