The current production process for processing snake fruit does not pay attention to water use efficiency, resulting in excess water use. Another problem that occurs is the large amount of liquid waste, which causes a strong odor and pollution of the water. One approach that can be taken to increase productivity while reducing environmental impacts is the Green Productivity (GP) model. The average value of productivity in the period January - September 2024 is 148.07% and the EPI Index is -27.50. In this research, efforts were made to handle liquid waste by proposing two alternative solutions. Alternative 1 is by adding a salak fruit mixer machine for efficient use of water and alternative 2 is by processing waste into biogas. Based on the alternatives proposed, alternative 2 was chosen as an alternative solution, namely making a liquid waste processing plant into biogas. This alternative was chosen because it can increase company productivity to 152.32% or provide a contribution of 4.25%. Alternative 2 also contributes to changes in liquid waste levels of the BOD5 variable by 89.70%, COD by 88.28%, TSS by 79.83%, as well as increasing the pH value by 61.59% so that environmental performance is better with an EPI index of -2.64.

PT Z produces gray fabric using the Picanol PAT-A Air Jet Loom. In May 2023, the company's efficiency declined, producing 56,432 meters of gray cloth, 73,15% efficiency, and a total grade C of 0,89%. The results fell short of the company's target of 67,800 meters with an 85% minimum efficiency of 85% and a 2% maximum grade C target. To address the low efficiency, research was conducted in June 2023 using overall equipment effectiveness (OEE) and six big loss analyses to identify improvement areas. The research method involves direct field observation of the machine monitor and literature study. It begins by measuring machine effectiveness using the OEE method, which includes calculating availability, performance efficiency, and product quality rates, and assessing the six big losses. The average OEE value is 67,28%, below the JIPM standard of >85%. Analysis of six big losses shows reduced speed losses at 39,14, idling and minor stoppage losses at 32, 18%, breakdown losses at 16,61%, and setup and adjustment losses at 11,16%. 16% yield loss at 0,92% and rework losses at 0%. Reduced speed losses are the main factor causing losses due to low engine operational speed below the ideal. Based on a fishbone diagram analysis, the main factor of reduced speed losses is the machine factor, namely the age of the machine 32 years, continuous use, worn machine parts, and difficult to find on the market. To enhance efficiency with modifying spare parts, re-establish a replacement schedule, and document all machine damage events.

Published: January 2025

High levels of neps are a critical problem in the carding process in the spinning industry because they will affect the quality of the sliver. The purpose of writing this paper is to reduce the level of neps from 6 neps/gram to 4 neps/gram according to company standards with the DMAIC (Define, Measure, Analyze, Improve and Control) method. The implementation of the DMAIC method in the textile and clothing industry is a successful strategy to reduce defects generated along the production line. At the defined stage using the Pareto diagram found the highest type of neps defect in the daily quality check of sliver carding. Cause and effect analysis with a fishbone diagram illustrates that the critical cause is the neglect of machine cleanliness according to the applicable Standard Operational Procedures. After making improvements with the DMAIC method, the neps level decreased from 6 neps/gram to 3 neps/gram, exceeding the standards set by the company. Although the results show a significant decrease in the number of neps, there is a small variation in weekly results that may be caused by environmental factors or variations in the production process that are not fully controlled. Further research is needed to understand these factors and control them more effectively. The results of this study indicate that the DMAIC method not only helps in identifying problems but also in implementing effective solutions. This study contributes to the theoretical benefits of DMAIC in process improvement and practically in the textile industry.

River water pollution in Bengkalis Regency, particularly in Bukit Batu River, has seen an increase in pollution levels that significantly affect water quality. This study aims to analyze the water quality and pollution load in Bukit Batu River, Bengkalis Regency, as well as to explore the socio-economic factors of the communities that depend on the river. Bukit Batu River plays an essential role in the local community's life, serving as a source of water for domestic and agricultural purposes, as well as supporting the fisheries sector. However, in recent years, the river's water quality has deteriorated significantly due to deforestation, land conversion for oil palm plantations, and pollution from domestic, agricultural, and industrial activities. This study employs a quantitative approach with methods including observation, in-depth interviews, and literature review. Water samples were collected at three observation points representing the upstream, midstream, and downstream sections of the river. The water quality data were analyzed and compared with the standards set in government regulations. The results show that in June and September 2024, the water quality of Bukit Batu River decreased, with parameters for BOD and COD exceeding the established quality standards. The increase in BOD and COD was primarily influenced by domestic waste, agricultural runoff, and weather factors such as high rainfall. In June, the water quality was slightly better due to clear weather, which reduced pollution activity, while in September, heavy rainfall increased the water flow, carrying pollutants into the river. The pollution load analysis indicated a rise in pollution in September, showing that water conditions change significantly depending on environmental factors and human activities around the river. The increased pollution load analysis suggests potential adverse impacts on the ecosystem and public health in the surrounding areas. This study is expected to provide recommendations for sustainable river management policies and to help maintain the water quality of Bukit Batu River within safe and healthy standards for both the ecosystem and local communities.

Climate change is increasingly contributing to the frequency and intensity of natural disasters, especially in archipelagic countries like Indonesia. This study aims to develop a predictive model for disaster risk levels using deep learning with climate and geographical variables. The simulated data includes variables such as average temperature, precipitation, humidity, wind speed, elevation, land cover type, and population density. The model was designed to classify disaster risk into four categories: no risk, low risk, moderate risk, and high risk. Data preprocessing involved normalization and an 80:20 train-test split. The model was trained using the Adam optimization algorithm with activation functions suitable for multi-class classification. Evaluation results show that the model can accurately predict disaster risk levels. This study demonstrates that simulated data can effectively support disaster risk prediction when observational data is limited. With further development using more comprehensive data, this model has the potential to be implemented in an early warning system to support decision-making in climate change mitigation in Indonesia.

The advancement of cloud computing technology has transformed the retail industry landscape, particularly through the adoption of cloud-based Point-of-Sale (POS) systems. This system not only simplifies store operations management but is also believed to improve the quality of customer service. However, studies that directly measure the impact of cloud-based POS implementation on customer experience and satisfaction remain limited. This study aims to explore the influence of cloud-based POS technology on enhancing customer service in the retail sector in Indonesia. This research employs a quantitative approach with a survey method. Data were collected from 100 respondents consisting of customers and retail store managers who have been using cloud-based POS systems for over a year. Data analysis was conducted using simple linear regression to determine the relationship between cloud-based POS system implementation (independent variable) and customer service improvement (dependent variable). The results show that the implementation of a cloud-based POS system has a significant and positive impact on improving customer service. The regression coefficient of 0.765 indicates that each improvement in cloud-based POS implementation contributes to an increase in customer service quality, including transaction speed, product information accuracy, and service personalization. An R-squared value of 63.4% indicates that most of the variation in customer service improvement can be explained by the use of cloud-based POS. This research makes a new contribution by demonstrating that cloud-based POS technology not only enhances operational efficiency but also significantly improves the quality of interaction and customer satisfaction. These findings can serve as a reference for retail industry players in adopting cloud-based POS technology as a strategy to enhance customer service and business competitiveness.
