Quality Control Analysis of Wood Pellet Products at PT XYZ Using the Seven Tools and New Seven Methods
Get PDFQuality is a factor that determines the success of a product in market competition. PT XYZ, which produces wood pellets, is experiencing problems related to the quality of its products. The company wants to control the quality of its products in order to reduce losses due to product defects. Product quality control is carried out using the seven tools method to determine the causes of defects and the new seven tools method which is used to see the corrective actions that must be taken based on the factors that cause product defects. The results showed that there are 3 types of defects in wood pellet products, namely water content that is too high, less density, and shape that is too small. From the total amount of 12,782 kg of defective products, 34.24% of them are the types of defects of too high moisture content, 30.50% defects of insufficient density, and 35.26% defects of too small shapes. The proposed improvements to prevent errors that can cause product defects can be done by tightening the implementation of company SOPs, improving worker performance and skills, optimizing machine performance, and improving the quality of the raw materials used

Is Indonesia Ready for a Sustainable Procurement Revolution in Goods and Services?
Get PDFIn the globalisation era, issues pertaining to sustainable development have assumed a position of paramount importance in the realm of international development. This phenomenon is further accentuated by the United Nations' establishment of the Sustainable Development Goals, which mandate that the developmental trajectories of nations worldwide must be aligned with the tenets of the SDGs. The ramifications of this directive extend to all facets of society, including the acquisition of goods and services. The present article thus seeks to undertake a comprehensive analysis of the procurement of goods and services based on sustainable principles within the Indonesian context. The present study adopts a dual approach, encompassing both a legal research methodology and a conceptual and statute approach. Sustainable procurement is the process of acquiring goods and services that take into account environmental, social, and governance factors. Its goal is to provide a positive impact on the environment, society, and economy. The benefits of sustainable procurement include enhancing reputation, cost savings, improving efficiency, reducing risks, increasing resilience, promoting innovation, and fostering growth. To implement sustainable procurement, organizations can use ISO 20400, an international standard that provides guidelines for developing a sustainable purchasing approach. Procurement of goods/services is essential for government activities, both at the central and regional levels, according to Presidential Regulation Number 16 of 2018 regarding Procurement of Goods/Services for the public The internalization process of sustainable procurement aspects includes implementing environmentally friendly procurement at every stage of procuring goods/services. Support for the sustainability of public procurement requires a rational and instrumental approach towards the community
The Immediate Bankruptcy Decision: The Role of Curators and Supervisory Judges in Ensuring Justice and Legal Certainty
Get PDFThis research examines the urgency of implementing an immediate bankruptcy decision in Indonesian bankruptcy law. The main issues raised were how bankruptcy judgments can be implemented even though they do not have permanent legal force, as well as how curators and supervisory judges ensure justice for creditors and debtors. The purpose of this study is to analyze the legal basis of instant judgments in bankruptcy, distinguish their application from ordinary civil procedure law, and examine how the principles of justice and legal certainty can be fulfilled in this process. The research method used is a normative juridical approach, with an analysis of primary and secondary legal materials, including Bankruptcy Law No. 37/2004, court decisions, and legal literature. The results of the study show that the bankruptcy verdict is immediate and provides a guarantee of rights protection for creditors by allowing the curator to manage the debtor's assets directly. This is supported by the role of the supervisory judge, who ensures that the curator's duties are carried out fairly. Although a bankruptcy judgment can be overturned at the cassation or review level, the actions taken by the curator remain valid and binding. The recommendations of this study are the importance of strict monitoring in the settlement process to ensure fairness for all parties, as well as the need to strengthen regulations to optimize the supervisory function by supervisory judges to maintain a balance between the rights of creditors and debtors
Comparison of Dimensionality Reduction Techniques to Improve Performance and Efficiency of Logistic Regression in Network Anomaly Detection
Get PDFNetwork anomaly detection is a crucial process to identify abnormal network traffic, which may pose a security threat. This research aims to improve the performance and efficiency of Logistic Regression (LR) in network anomaly detection by applying dimension reduction techniques, such as Principal Component Analysis (PCA), Truncated Singular Value Decomposition (TSVD), t-Distributed Stochastic Neighbor Embedding (t-SNE), and Independent Component Analysis (ICA). The performance of each dimension reduction method is evaluated based on accuracy, precision, recall, F1-score, and computation time. The results show that TSVD provides the best performance with 95.86% accuracy, 0.96 precision, 0.96 recall, 0.95 F1-score, and 13.83 seconds computation time. In contrast, ICA showed the worst performance, especially in precision, recall, and F1-score, with values of 0.73, 0.83, and 0.78, respectively. Meanwhile, although t-SNE produces competitive accuracy, it has a high computational cost with an execution time of 1698.54 seconds. These findings show that choosing the right dimension reduction algorithm not only improves detection performance but also supports data processing efficiency, making it highly relevant for large-scale network security scenarios. Keywords: dimensionality reduction, Logistic Regression, network anamoly detection, performance evaluation, Truncated Singular Value Decomposition
