Taman Safari Indonesia (TSI), an ex-situ conservation institution in Puncak, Bogor, has developed the 4A framework to attract more tourists and enhance visitor satisfaction and loyalty, while increasing visits revenue. It has also raised the carbon footprint of tourist transportation. This study aims to analyze the vehicle emissions of tourists and their satisfaction with 4A components to predict the likelihood of repeat visits and the subsequent rise in carbon emissions. Emissions were calculated using the IPCC 2006 Guidelines (Tier 2), and the relationship between tourist satisfaction and loyalty was assessed using the structural equation model partial least squares (SEM-PLS) method. The results indicated that CO2 emissions from tourist vehicles during holidays reached 1,482,261.96 g.CO2/h, significantly higher than the 552,732.81 g.CO2/h recorded on weekdays. The analysis also revealed that tourist satisfaction and loyalty towards the 4A components significantly positively impacted the intention to revisit, as demonstrated by the T-statistics of 5.437 and P-values of 0.000, where the more satisfied the tourists are, the more loyal they are to return to TSI. Keywords: carbon footprint, IPCC, loyalty, satisfaction, SEM-PLS

This study examines the production capacity challenges faced by PT RAS following the launch of RAS Gleam in November 2023. The significant increase in demand has put pressure on the production, filling, and packing workstations, leading to potential bottlenecks in fulfilling orders. To address this issue, time-series forecasting was applied to project demand for the next year for three products: RAS Self-Cleaning, RAS Instant Antifog, and RAS Gleam. These forecasts guided the development of a Master Production Schedule (MPS) to align production with projected demand and informed Rough-Cut Capacity Planning (RCCP) to identify capacity constraints. The analysis revealed gaps between available and required work hours, particularly during peak periods. To bridge these gaps, the study proposed workforce management solutions, including a controlled overtime system and the strategic use of freelance workers for filling and packing workstations. These measures enabled PT RAS to meet demand while complying with Indonesian labour regulations. The findings demonstrate how accurate forecasting, workforce optimization, and flexible labour management enhance production efficiency and operational flexibility at PT RAS. By forecasting demand, PT RAS can prepare for future conditions, ensuring it has the capacity to meet demand.

The spray painting process at PT Tritek Indonesia plays a vital role in determining final product quality, especially for components used in the automotive and electronics industries. However, recurring defects such as NG total and under paint have led to elevated production losses and pose risks to customer satisfaction and process stability. This research aims to identify the root causes of these defects and propose structured improvements using the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) methodology. During the Measure phase, data from January to March 2025 indicated that defect rates remained high, with DPMO values of 116,160 (? = 1.19), 89,553 (? = 1.34), and 110,861 (? = 1.22) respectively, highlighting low process capability and the need for urgent improvement. Root cause analysis using Fishbone Diagrams and FMEA identified several key contributors to the high defect rate, including the lack of operator discipline in pretreatment and thickness inspection, inconsistent spraying techniques, suboptimal spray gun performance due to nozzle wear, and dusty spray booth conditions. To address these root causes, the proposed solutions in the Improve phase include implementing a daily pretreatment checklist, structured coating thickness inspections with periodic training and microbreaks, development of a spray painting assistive tool to standardize distance and angle, a preventive maintenance schedule for spray gun components, and the implementation of 5S principles to improve cleanliness in the painting area. The Control phase proposes regular audits, performance documentation, and bi-weekly evaluation meetings to ensure long-term compliance. This research provides practical insights for small-to-medium manufacturing enterprises in Indonesia to initiate structured quality control programs and gradually advance towards higher process capability and reduced defect variability.

The Coal Handling Facility (CHF) functions as the principal conveyor line responsible for delivering coal to the coal-fired power plant. Coal extracted from the mining face is transported by dump trucks over an average distance of approximately five kilometers before being transferred to the conveyor system, which subsequently channels the coal to the power plant. In parallel, overburden materials are transported to designated disposal sites located about four kilometers from the mining area. These operational conditions underscore the necessity of optimizing the CHF route to enhance overall system efficiency. This study investigates the operational constraints and develops strategies for improving coal supply chain performance to the power plant. The research employs the Six Sigma methodology, utilizing its structured problem-solving framework : Define, Measure, Analyze, Improve, and Control (DMAIC), to propose optimization measures aimed at enhancing efficiency and reducing operational costs for the company. Keywords: Coal Handling Facility (CHF); Coal fired Power Plant; Conveyor; Six Sigma; Cost Reduction; Define, Measure, Analyze, Improve, and Control (DMAIC)

CV PG STTT is a garment manufacturing company that specializes in producing chemical laboratory coats and technical PDL (Personal Duty Line) shirts. The company operates on a make-to-order system. However, its production processes remain entirely manual, resulting in challenges related to production monitoring, tracking, and recording. Furthermore, the company still adheres to a linear economy model, where production waste is discarded without being repurposed. To address these issues, the implementation of an extended work order management system using a circular economy approach offers a viable solution. This approach not only minimizes production waste but also enhances the monitoring of production processes. The extended work order management system is developed using the Accelerated SAP (ASAP) methodology. The research follows several stages, including observation, interviews, analysis, and the proposal of a system design through configuration and adjustment of manufacturing modules, followed by testing the manufacturing modules. The outcome of this study is an ERP system on Odoo with customized module to align with the company's business processes and proposed workflows. This system simplifies production processes at CV PG STTT while promoting sustainability and supporting the transition to a circular economy.
