Abstract

According to the World Health Organization (WHO), 15 – 30% of the world's population suffers fromdigestive tract diseases every year, and Indonesia ranks third with the most cases. This tragedyprompted the pharmaceutical industry to maximize production of antacid drugs. One of them isspeeding up the analysis process for antacid medications without compromising the accuracy of theanalysis results. This research aims to increase productivity by identifying waste activities, makingimprovements using a lean approach, and adopting I4.0. The research results stated that the mainwaste occurred in an ineffective process, namely the titrant solution standardization process and notutilizing resources with automation technology. After the future state value stream mapping wasdesigned, the total lead time decreased from 35,760 seconds to 26,940 seconds and the total distancefrom 225 meters to 115 meters, so with the proposed improvements, there was an increase inprocess cycle efficiency (PCE) from 36.07% to 42.87%.

Abstract

This research discusses the analysis of work posture in the MMH activity of lifting products from thebending workstation to the Quality Control (QC) and packaging workstation. Observations weremade on the operator's working posture at the bending workstation in Kobar, Ltd, which producesrear brake components. The problems found were manual material handling activities in the form ofrepetitive lifting and placing products from the bending workstation to the QC and packagingworkstation. Work posture analysis was done using the Nordic body map questionnaire, REBA, andOWAS methods. Based on the results of the NBM questionnaire, fatigue occurred in the right elbow,left elbow, upper back, lower back, lower wrist, right wrist, and left wrist.Meanwhile, the results of the REBA method obtained a score between 4-7, which means that MMHactivities have a moderate risk and immediate improvement. Apart from that, based on the OWASmethod, a score of between 2-3 is obtained, so improvements must be made as soon as possible. Theimprovements made were by designing material handling tools using the principles of kaizenkarakuri and anthropometric ergonomics. This improvement eliminates the element of manualmaterial handling work and changes the position of the layout.

Abstract

Horizontal Directional Drilling (HDD) is a drilling technique that does not damage the groundsurface; the HDD process involves a stage that requires high concentration and physical skills and isoften carried out in challenging working conditions, causing mental Workload and fatigue in HDDworkers. HDD workers should be given improvements in their work methods to be safe whenworking due to being too tired or losing focus. HDDs must be monitored in real-time, which requiresworkers to get good results without errors so that workers experience workload pressure andmental fatigue. This study aims to measure and minimize mental Workload and fatigue in HDDworkers and determine improvement proposals based on the why-why diagram. Mental workloadmeasurement using the RSME method and fatigue using SOFI and why diagrams are used to findcause and effect in mental Workload and fatigue experienced by HDD workers. Based on the analysisof RSME, the scale value obtained based on six indicators of WL, WD, WP, WME, WA, and WF is 92.05,which is in the category of enormous business carried out, and the KiK indicator or fatigue gets thehighest scale value of 106.52 with the business category given is very large so that HDD workersexperience a mental workload. Mental workload and fatigue correlate. Based on the results of SOFI,the sleepiness dimension received a score of 21.83 with a high level of fatigue category. Therefore,the proposed improvement to the causal results of the Why Diagram is adding the workforce,adjusting work shifts, and monitoring and evaluating HDD workers.

Abstract

Kenaf fiber is one of plant-based fibers used as an industrial raw material. The business model canvasin this study was an approach used to describe the business model of kenaf fiber agro-industry in theupstream supply chain network. This study aimed to identify value propositions, structural models ofdevelopment strategies, and to design a business model canvas for the agro-industry. AnInterpretative structural modelling method was used to construct a structural model for thedevelopment strategy, and the business model canvas was used to describe this agro-industrybusiness model. BMC is a framework that helps business people describe the current business model.This approach is a static approach that uses past data. However, this approach becomes dynamicafter being integrated with certain scientific methods so that it is able to describe its business modelin the future. The structural model identified that the prominent element that had the significantinfluence on this business was seed suppliers, while the prominent element in development of thisagro-industry strategy was an institution. This research is still limited to the upstream supply chainnetwork, therefore, future research can be developed on the mid-stream and downstream supplychain networks.

Abstract

Service quality is a fundamental principle of a service-oriented firm. High service quality is crucial forservice organizations to remain competitive and retain customers, preventing them from switchingto other providers. PLP is a firm that specializes in providing maintenance services for electrical andlighting systems. With a sample size of 28 respondents, a preliminary customer satisfaction surveywas conducted. The survey revealed that 32% of the customers were dissatisfied with the service,while 7% were very dissatisfied. However, these scores did not meet the desired level of maximumcustomer satisfaction. The objective of this study is to evaluate the level of customer satisfaction withthe electrical and lighting maintenance services provided by PLP, and to identify the specific featuresthat need improvement and should be given priority. This research employs the amalgamation ofservice quality, importance-performance analysis (IPA), and Kano techniques. The disparity betweenthe significance and execution is seen in customer satisfaction. A survey was sent to a total of 45patrons of PLP Company. SPSS determined all the questions in this questionnaire on five qualityfactors. The study's gap scores for dependability, responsiveness, assurance, empathy, and tangiblesare as follows: -0.364, -0.409, -0.467, -0.462, and -0.111. This suggests that consumers of PLP aredissatisfied. Subsequently, this research identified six service qualities that need improvement.
