Abstract

PT. Niaga Nusa Abadi is a company engaged in sales, distribution and marketing. Established in 2012. It is known that PT. Niaga Nusa Abadi has never carried out an energy audit since the company was founded. After collecting data, it can be seen that the lighting and air conditioning in several rooms do not comply with SNI standards. Energy audit technique used to calculate the amount of energy consumption in a building. Energy Consumption Intensity (IKE) is the quotient between total energy consumption during a certain period (one year) and the building area. The IKE unit is kWh/m2 per year. Energy saving opportunities are the potential to reduce energy use in a particular system or process in an efficient manner without compromising comfort. PT. Niaga Nusa Abadi has an area of ​​713.42 m2, an office with an area of ​​139.5 m2 and a warehouse with an area of ​​574.24 m2. After carrying out calculations, it can be seen that the initial energy audit is 52.77 Kwh/m2 per year. Carrying out detailed energy audit calculations of 46.79 Kwh/m2 per year. Recalculating the energy audit after carrying out improvements to lighting and air conditioning, it was found to be 52.27 Kwh/m2 per year. After making improvements to the lighting system and air system (AC), it is ideal and meets SNI standards. IKE after making improvements amounting to 52.27 kWh/m2 per year. IKE after carrying out repairs experienced an increase of 10% but the suitability and comfort of building users can be fulfilled and can increase user productivity

Abstract

This study aims to optimize the quality control of wood pallet products at PT. Azdhi Kayu Kreasi by using the Root Cause Analysis (RCA) and Statistical Process Control (SPC) approaches. The problem faced by the company is the high level of product defects that can reduce customer satisfaction and increase production costs. The RCA method is used to identify the root cause of product defects, while SPC is used to monitor and control the production process. Data were collected through field observations, interviews, questionnaires, and internal company documentation. The data were analyzed using P charts, Pareto diagrams, and fishbone diagrams. The results showed that the main cause of product defects was wood cracking, which was caused by factors such as poor raw material quality, production process errors, and unsuitable environmental conditions. The implementation of RCA and SPC proved effective in identifying and reducing the causes of product defects. By making improvements to the production process and selecting better raw materials, the product defect rate can be significantly reduced. This research makes a practical contribution to the company in improving product quality and production process efficiency.
