Abstract

Farming in cultivation always faces challenges, including land/land area, acquisition of superior seeds, fertilization, maintenance and labor. As a result of these uncertain risks, farmers are encouraged to always have high motivation, be creative and innovative, and dare to take risks by responding to existing opportunities. Therefore, it is necessary to make maximum efforts in providing understanding to farmers to carry out sugarcane cultivation. Problems inevitably arise because they dare to take unnecessary risks, so it requires questions in dealing with the impact, so risk mitigation is needed to reduce risk. Therefore, the purpose of this study was to determine the highest risk in the sugarcane planting process in increasing productivity. Data was collected by documentation through the distribution of questionnaires. The method used in this research is FMEA (Failure Mode Effect Analysis) based on ex ante, interactive and ex post strategies. The results of this study are Risk mitigation against the highest risk, the first is to make a good irrigation system, the second is to give pest control drugs in accordance with the provisions and the third is to pay attention to kletek time and carry out klentek properly.

Abstract

The study on improving the facility layout at CV. Surya Mega Yokasa demonstrated that the Systematic Layout Planning (SLP) method significantly enhances the efficiency of the production process, with a total reduction in material displacement distance by 13.45 meters and an efficiency increase of 16%. These findings imply that careful consideration of workflow and qualitative factors in layout planning can markedly optimize production flow and reduce congestion. However, the study did not factor in the Material Handling Costs (MHC), suggesting that future research should integrate MHC analysis to provide a more comprehensive evaluation of layout effectiveness and further optimize production efficiency. Highlight: Efficiency Boost: SLP reduced displacement by 13.45m, increasing efficiency by 16%. Improved Workflow: SLP method improved production flow, reducing congestion. Future Focus: Include Material Handling Costs for better layout evaluation. Keywoard: Systematic Layout Planning, Blocplan, Production Efficiency, Material Flow, Facility Layout

Abstract

This study investigates the root causes of defects in recycled paper production, focusing on GSM-related issues, and proposes solutions to mitigate these defects. Through a six-month data collection process involving observation, on-site inspections, surveys, and expert interviews, the research employs Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) methodologies to identify key factors contributing to defects. Results reveal seven types of defects, with GSM defects being most prominent, attributed to factors such as insufficient training and inadequate supervision. Proposed improvements include enhanced training, raw material inspections, and improved monitoring practices. These findings offer valuable insights for the paper production industry, suggesting practical interventions to enhance product quality and production efficiency. Further research could explore additional methodologies such as Root Cause Analysis (RCA) or Six Sigma for continuous quality improvement. Highlights: 1. Thorough analysis: FMEA and FTA methodologies for defect root cause identification.2. Recommended solutions: Enhanced training and monitoring for quality improvement.3. Industry insights: Practical strategies to enhance production efficiency and product quality. Keywords: Recycled paper production, Defects, Root cause analysis, Improvement strategies, Quality enhancement

Abstract

PT. XY, a textile company specializing in woven sarongs, faces fluctuating demand during Islamic religious celebrations, impacting production. In Ramadhan 2023, production increased by 30%, but warp yarn availability was insufficient. This study forecasts warp yarn production over twelve periods, comparing Double Exponential Smoothing Holt’s (DES) and Holt-Winter’s Exponential Smoothing (WES) methods, optimized using the golden section method. Using historical data from January 2021 to April 2023, WES with golden section parameters (α1 = 0.67387, β1 = 0.08756, γ2 = 0.85408) achieved the best accuracy with a MAPE of 5.5437%. The WES method is recommended for improving production planning at PT. XY, with future research suggested to explore production correlations and procurement costs. Highlight: Demand Fluctuation: PT. XY experiences significant demand changes during Islamic religious celebrations. Forecasting Methods: Comparing DES and WES methods for predicting warp yarn production. Optimal Accuracy: WES with golden section optimization achieved the lowest MAPE of 5.5437%.
