The economy of a country is basically supported by many sectors, one of which is the automotive industry sector with the designation as a provider of transportation facilities. The policy regarding transportation facilities is supported by the ministry of industry which issued a policy on environmentally friendly cars or low cost green cars (LCGC). Apart from being environmentally friendly, the car also has an affordable price in the community. Forecasting sales of LCGC cars is important for many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to company targets. This will have an impact on the life and death of the automotive industry sector in the region. Important forecasting is done by many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to the company's target. The data used in this research is secondary data. The secondary data needed in this study is the data on LCGC car sales in Indonesia from December 2019 to November 2020 obtained from secondary data sources. The data analysis method used in this research is exponential smoothing and trend analysis using POM QM software for Windows. The results also show that a good method to use as a sales forecasting method is the exponential smoothing method. This is because this method has a smaller MAPE value than the MAPE value in the trend analysis method. The MAPE figure for exponential smoothing is 4.9%, while the MAPE figure on the trend analysis method is 6.69%. In the exponential smoothing method, it is predicted that the sales of LCGC type cars in the next period are approximately 8448 units, while according to the trend analysis method, the sales forecast for the next period is 3894 units.

Sustainability was based on three main baselines (economic, social, and cultural). Currently, a tool needed to assessment sustainability and develop a competitive strategy for these SMEs. However, the tools for sustainability assessment in SMEs was not available. This study aims to develop a sustainability assessment tool in the SMEs sector. Multi-Criteria Decision Making (MCDM) was a framework that supports the decision-making process by combining several baselines. One of the MCDM methods that can be used was the Analytical Hierarchy Process (AHP).

Warehouse SSI 3 of PT. Sami Surya Indah Plastik is a polymer raw material storage facility of approximately 1,088 m², storing main raw materials (HDPE, LLDPE), supporting materials (metalonce, pellet, calcium), and external raw materials. The existing layout suffers from misplaced raw materials, the absence of grouping based on movement frequency, and dependence on a single operator, resulting in an average waiting time of up to 30 minutes. A physical constraint also exists in the form of a maximum stacking limit of 2 pallets due to safety factors. This study analyzes the suitability of raw material placement, designs a proposed layout using ABC classification and class-based storage (CBS), and compares performance using historical data from January–December 2025. The ABC classification results formed the basis for the proposed storage zoning, evaluated through FlexSim simulation. The proposed layout reduced total material handling moment from 59,013,313.97 kg/m to 49,688,902.90 kg/m and weighted average distance from 13.38 m to 11.27 m, each with 16% efficiency.

CV. Bebetrend Garment Sukoharjo is a garment company whose core process lies in the sewing department. Observations of three sewing machines (two collar-attaching machines and one sleeve-hemming machine) during May–June 2026 revealed considerable downtime, unstable production speed, and a notable level of defective output. This study aims to measure sewing machine effectiveness using the Overall Equipment Effectiveness (OEE) method and to identify the dominant causes of loss through Six Big Losses analysis within a Total Productive Maintenance (TPM) framework. The research employed a quantitative descriptive approach using primary and secondary data obtained through observation, interviews, and company production records. The results show that the OEE values of the three machines ranged from 63% to 70%, well below the world-class standard of 85%, with availability (82.5%–85.2%), performance (80.7%–87.7%), and quality rate (95%–96%) all falling short of JIPM standards. Six Big Losses analysis identified reduced speed losses as the largest contributor, averaging 11.15%–17.20%, followed by breakdown losses averaging 9.06%–10.46%.
