Abstract

Big Data-based Business Intelligence (BI) systems have evolved into autonomous profiling and decision-making engines, triggering ethical dilemmas and privacy violation risks. This study aims to analyze the intersection between Information Technology (IT) professionalism ethics, BI architectural implementation, and compliance with Law Number 27 of 2022 concerning Personal Data Protection (UU PDP). Utilizing a Design Science Research (DSR) approach combined with a normative-juridical review, this study evaluates software engineering practices through data exploitation case studies in Indonesia. The results indicate that the UU PDP mandate and international codes of ethics demand the proactive adoption of Privacy by Design (PbD) and Data Protection Impact Assessment (DPIA) starting from the requirement analysis phase. As a practical contribution, this research proposes the Ethically-Aligned Business Intelligence (E-BI) framework featuring a five-layer architecture to integrate ethical controls, ensuring BI systems operate fairly, transparently, and respect data subjects' rights.

Abstract

This study applies the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm to the UK Smoking Survey Dataset from Kaggle (1,691 records, 13 attributes). Preprocessing includes missing value imputation, label encoding, feature selection of 8 features, and StandardScaler normalization. Optimal parameters (eps=2.0; min_samples=15) were determined via K-Distance Graph. Four clusters were identified: Cluster 0 (n=539, male non-smokers, avg. 51.2 yrs), Cluster 1 (n=228, female smokers, 11.9 cig/weekday), Cluster 2 (n=731, female non-smokers, avg. 53.0 yrs), Cluster 3 (n=168, male smokers, 13.5 cig/weekday), and 25 noise points as extreme heavy smokers. Evaluation: Silhouette Score=0.2032, Davies-Bouldin Index=2.0494, Calinski-Harabasz Index=395.68. Results demonstrate DBSCAN’s effectiveness in identifying demographic-based smoking behavior patterns.

Abstract

Inventory and repair management are essential aspects in supporting organizational operational performance. The UPT Workshop of Signal, Telecommunication, and Electricity Unit (Sintelis) at PT. Kereta Api Indonesia (Persero) Daop 7 Madiun still applies a manual recording system for inventory and repair management, which may cause data inaccuracies, reporting delays, and difficulties in data retrieval. This study aims to design and develop a web-based inventory and repair information system to improve efficiency and data accuracy. The research method used is Research and Development with the Rapid Application Development (RAD) approach, which consists of requirement planning, design workshop, and implementation stages. Data were collected through observation, interviews, and documentation studies. The results indicate that the developed system is able to manage inventory and repair data in an integrated manner and generate reports automatically. System testing using the black box testing method shows that all system functions operate according to user requirements. Therefore, the developed information system can serve as an effective solution to support inventory and repair management at the Sintelis Unit.
