Abstract

PT. Hamdan Jaya Makmur is a company that runs in the field of Machining, Engineering, Fabrication, Stamping, and Trading Company, which produces products for small, medium and modern industries. Less than optimal maintenance system with corrective maintenance causes PT. Hamdan Jaya Makmur often experiences machine failure. Based on historical data, it can be seen that the lathe machine type SS-850 experienced very high downtime. Therefore, it is necessary to plan optimal and preventive maintenance of the machine in order to produce according to the target and increase the reliability of the machine. The purpose of this research is to determine the time interval and cost of preventive replacement on components of the lathe machine type SS-850 at PT. Hamdan Jaya Makmur. The method used in this research is the Age Replacement method, namely by determining critical components, determining the distribution pattern of damage, determining distribution parameters, and calculating MTTF and MTTR, where the results obtained are preventive replacement time intervals, and calculating preventive replacement costs. The results obtained from this research are that there are four critical components on the lathe machine type SS-850, namely electric components with a preventive replacement time interval of 11 days and a preventive replacement cost of Rp.3,080,679,253, bearing components have a preventive replacement time interval of 14 days and a preventive replacement cost of Rp.4,931,989,307, the gearbox component has a preventive replacement time interval of 33 days and a preventive replacement cost of Rp.11,621,532,829, and bolt and nut components have a preventive replacement time interval of 11 days and a preventive replacement cost of Rp.1,615,296,412.

Abstract

PT. XYZ is a company that produces pharmaceutical products for livestock. Most of the raw materials for veterinary drugs consist of B3 powder (toxic and hazardous materials). Waste from the production process is unavoidable, one of the types of waste produced by PT. XYZ is B3 powder wastes. According to the Environmental Service (DLH) B3 waste cannot be directly discharged into the environment, therefore PT. XYZ uses 3rd party services in processing B3 waste disposal. PT. XYZ produces powdered B3 waste at an average of 267.12 kg/month, the cost that must be incurred by the company to manage B3 waste and the value of loss of raw materials is Rp. 28,094,703.70/year. This study aims to design a system for the minimization of B3 waste by using a Soft System Methodology (SSM) approach. The proposed changes from this research use the 3R principle (reduce, reuse, recycle). The implementation of the proposed changes can result in cost efficiency incurred by the company for B3 waste management of Rp. 18,368,995.87/year.

Abstract

The environmental uncertainty due to the COVID-19 pandemic poses severe challenges for all parts of the supply chain in the tourism industry. The focus of the Indonesian government is to improve the condition of the tourism industry, which has experienced a decline in the number of tourists due to the COVID-19 pandemic. A supply chain tourism industry framework was developed through the Support System Facilities (SSF) variable to map the actors in the tourism industry activities in an uncertain environment due to COVID-19. The method in this study uses a qualitative descriptive approach through in-depth interviews, direct observation, and literature study. The results of this study are the tourism industry supply chain conceptual framework which states that there are several stages in distributing services and support systems and facilities to tourists, namely through suppliers, tour operators, tour agencies, and tourists. This finding has practical implications for the government in making a policy strategy.

Abstract

The development of digital technology has encouraged the adoption of Augmented Reality (AR) as a strategic innovation in various industries, but its application in Indonesia remains limited due to low awareness and a lack of an integrated innovation strategy. This research aims to develop a strategy to strengthen AR technology through the integration of the Stimuli-Organism-Response (SOR) model, the concept of Open Innovation (OI), and Organizational Performance (OP), with a case study on PT. X in the city of Bandung. A mixed methods approach was applied, combining qualitative and quantitative analysis using the Fuzzy Analytical Hierarchy Process (F-AHP) method to determine the priority of the strategy, as well as Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the relationships between variables. The results showed that stimuli in the form of interactivity, augmentation, and AR aesthetics had a significant influence on internal organizational factors (organisms) and subsequently affected user behavioral responses, including reuse intentions. Meanwhile, open innovation plays an important role in strengthening organizational competitiveness through external collaboration, with inbound innovation being the most dominant factor. The research also resulted in three main strategies: improving interactive features and user experience, developing high-quality visual content, and strengthening collaborative networks through open innovation. The integration of SOR, OI, and OP models has proven effective in shaping a holistic, data-driven AR development strategy. The conclusion states that this approach can increase the adoption of digital technology and make a real contribution to organizational performance and digital economic growth in Indonesia.

Abstract

PT XYZ faces challenges in declining product quality due to production defects exceeding the optimaltolerance limit of 2% per period for six consecutive periods. This research aims to identify and addressdefects, offering action strategy recommendations to mitigate and prevent their recurrence during theproduction of grey fabric on RRC shuttle loom machines. The study utilizes an integrated analysis method,combining Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA). The researchhighlights five major defect types in grey fabric products, constituting 80% cumulatively. These defectsinclude pickbar issues, ambrol (fraying), tears, broken threads, and skipped weaving. Twelve root causescontributing to these defects in RRC shuttle loom production are identified and evaluated based on theirRisk Priority Number (RPN), categorized into classes A, B, and C with varying risk intensities. Two rootcauses from Class A, constituting 20% cumulatively, are identified as primary defect causes. These issuesinvolve the fit of the weaving reed and discrepancies in the let-off and take-up motion mechanism on theloom machine, each with an RPN value of 648. Action strategy recommendations are provided for thesetwo root causes, collectively contributing to 20% of the overall problem percentage. The objective is toprevent the recurrence of the five major defect types, accounting for 80% of the cumulative percentage.This comprehensive approach aims to rectify the identified issues, ensuring a higher standard of productquality in the textile manufacturing process

Abstract

The decline in the performance of the food and beverage sector by -3% for the food sector and -26.39% for the beverage sector in the second quarter of 2020 due to the outbreak of Covid-19 necessitated an analysis of the sustainability of the food and beverage industry. This research aimed to analyze the sustainability of the industry. A monitoring system for the sustainability of the food and beverage industry was an essential tool to ensure that the sector operated sustainably and contributed positively to the environment and society. Multidimensional Scaling (MDS) could be used to analyze and visualize the sustainability performance of the food and beverage industry based on various relevant dimensions or factors. The simulation results of Rapid Assessment of Food and Beverages (RAP-FB) indicated an overall high level of sustainability at 64.89%. In summary, the research showed that the food and beverage (F&B) industry's sustainability could be assessed through various dimensions and factors (such as Gross Domestic Product (GDP), energy efficiency, and workplace safety) contributed significantly to its overall sustainability. The monitoring system based on MDS could provide valuable insights to enhance the industry's performance and ensure its continued positive impact on the environment and society.
