Abstract

CV. XYZ found barriers that could hinder the implementation of a sustainable supply chain in the company. However, the company does not have a resolution method for determining the priority barriers that most influence the implementation. The aim of this research is to determine the barriers that influence the implementation of a sustainable supply chain. Settlement is carried out using the DEMATEL-ISM method. The research results show that the most influential barriers are lack of regulation and guidance from the government (A9) and high initial investment (A1). Because in the DEMATEL-ISM integration, these two factors were found to be located at the lowest level, which is the level with the most influential barriers, which are the main drivers. As a result, companies need to prioritize lack of regulation and guidance from the government and high initial investment as a basis for evaluation and improvement in implementing sustainable supply chains.

Abstract

Internet of things (IoT) becomes the backbone of the advanced countries and it has a real contribute to exchange the traditional style or way of practical life, even personal life into smart style, with (IoT) technology the life become more and more easy and professional. internet of things achieves various applications coordinate with sensors and standard protocols to apply what is called machine -to- machine connection (M2M), in this paper we will talk more about the concept of (M2M), the main component of internet of things and finally the common protocols that is used in network, in addition to that this work present an IOT operation with processing system using camera for capturing image and Xilinx system generator(XSG)models for designing image processing algorithms and the result of the processing is an image with black and white for edge detection and Thresholding models and gray color image for gray enhancement model.

Abstract

PT.XYZ is a company engaged in manufacturing, specifically in the production of granulated sugar. The problem that occurs in this company is the increasing number of gravel sugar defects by 18% or 1,019.52 tons. This number far exceeds the defect limit set by the company of 5% or 283.2 tons per month. Therefore, the purpose of this study is to identify the risks of the sugar production process using the House of Risk (HOR) method and determine the best alternative for priority risk mitigation through the Analytic Network Process (ANP) method at PT.XYZ. The HOR method is used to identify and classify risks based on severity and likelihood. Furthermore, the ANP method is used to determine the priority of risk mitigation strategies by considering the interdependence between risks. The results of the study showed that through the Focus Group Discussion (FGD) approach, 25 risk events and 25 risk sources were obtained which will be used to determine the mitigation strategy in the House Of Risk (HOR) method. Based on the calculation results of the rate agreement for alternative (W) of 0.777778, it shows a fairly high level of conformity among respondents' answers in selecting risk mitigation alternatives. Based on the calculation results on the super decision software, the highest normalized value was obtained, namely in the Desuperheater alternative of 0.51145. With this research, it is expected to help companies in overcoming company problems and can increase profits for the company.

Abstract

Warehouses play an important role in maintaining product quality until the product is delivered to consumers. The many important activities in the warehouse require companies to improve their performance to be effective and efficient in order to maintain trust. ABC Company is a private company engaged in civil construction, landfilling, cut and fill, heavy equipment rental, and spare part distributor. In warehousing activities, there are various activities that don’t have value added or waste. This study aims for identify waste and provide recommendations for improving warehousing activities. The implementation of Lean Warehousing is carried to identifying the warehousing flow process with Value Stream Mapping (VSM), then identifying 7 wastes that occur in the warehousing process using the Waste Assessment Model (WAM) method. The results of the study showed that the waste with the highest percentage level was waste inventory (I) waste overpurchase (O) waste defect (D). From the proposed improvements and Future stream mapping, it was found that the lead time was reduced to 544 minutes, which eliminated 200 minutes of non- value added activity. So that activity increased by 27% from the initial condition.

Abstract

The production of carton boxes is an energy-intensive process that generates various contaminants, polluting water and air, and affecting both ecology and human health. This study focuses on the environmental impact during the carton box production process at PT XYZ, aiming to calculate and analyze the environmental impact while measuring the eco-efficiency level of the production process. The research method employed in this study is quantitative descriptive, with primary data sources consisting of interviews, while secondary data includes company reports. Data were processed using SimaPro software and the Eco Indicator 99 method. Eco-efficiency measurement was conducted using the Life Cycle Assessment approach. The results indicate that the production of 1 ton of carton boxes generates an environmental impact of 315 Pt, with the largest contributions coming from the corrugating, folding, and customer delivery stages. The eco-cost value was IDR8,922,503, yielding an eco-efficiency index of 1.34, indicating that the production process is environmentally friendly and economical. However, the eco-efficiency ratio of 25.6% is still considered low, necessitating improvements in energy efficiency and emission reduction. Recommended improvements include substituting fossil fuels with renewable energy, selecting environmentally friendly suppliers, and replacing or modifying machinery to enhance efficiency and reduce emissions.
