Abstract

This study aims to identify waste in the 3 kg LPG delivery process at PT Nahatolu Miragas Prima and provide improvement proposals to improve distribution efficiency. The main problem is the delivery lead time that exceeds the estimated ideal time, causing delays to distribution partners. The method used is lean distribution with steps such as data collection of the distribution process, process flow mapping using Value Stream Mapping, and identification of waste based on 8 types of waste. Weighting was done through a questionnaire to determine the most dominant waste, followed by cause analysis using fishbone diagrams and formulation of improvement proposals using the 5W+1H approach. The results showed that the main wastes were in the waste activities of waiting, excess processing, and non-utilized talent. The application of future stream mapping shows the potential to significantly reduce distribution time by reducing the lead time of the distribution process from 732 minutes to 574 minutes. In conclusion, the lean distribution method is effectively used to identify and reduce waste in the LPG distribution flow by increasing the activity of the 3 Kg LPG distribution process by 21,5%.

Abstract

This study aims to develop an environmentally friendly crystal salt packaging design using the House of Sustainability (HoS) approach at PT Baruna Energi Solusindo Teknik. The methods used include observation, questionnaire distribution, and literature study to identify consumer needs through Voice of Customer (VoC), as well as mapping sustainability attributes with Quality Function Deployment (QFD). The analysis showed that the use of HDPE plastic in packaging results in high carbon emissions and energy consumption. Based on VoC, the most prioritized attributes for consumers are environmental health, safety, and product price. The most influential technical responses in packaging design are the type of eco-friendly material, product durability, and pollution control. The proposed alternative packaging uses kraft paper material with a size of 33 cm × 33.5 cm and a transparent window to display the product contents. This design is considered to fulfill the overall technical, aesthetic, and sustainability aspects. In conclusion, the implementation of the House of Sustainability is effective in supporting environmentally friendly packaging design and strengthening green supply chain management in the company.
