Stock price prediction remains a complex challenge due to the dynamic and non-linear nature of financial markets, especially for banking stocks like PT Bank Negara Indonesia (Persero) Tbk (BBNI). This study aims to optimize BBNI stock price forecasting by integrating an automated Extract, Transform, Load (ETL) pipeline with the Long Short-Term Memory (LSTM) algorithm within a data engineering framework. Historical data from 2019 to 2025 were processed through a structured ETL sequence—including data cleaning, feature engineering, and MinMaxScaler normalization—to ensure high data quality. The dataset was partitioned into 80% for model training and 20% for testing to ensure rigorous evaluation. The results demonstrate that the systematic ETL approach significantly enhances model stability and predictive accuracy compared to conventional methods. The LSTM model effectively captured long-term temporal dependencies, providing reliable trend forecasts with an impressive test accuracy, achieving a Root Mean Squared Error (RMSE) of 0.0354. This research underscores that integrating robust data engineering practices with deep learning is essential for building resilient financial decision-support systems.

Narcotics are a frightening scourge on society. Drug use is a pathological behavior that is harmful both to the individual and to society. The widespread use of drugs in Indonesia prompted the government to issue Law No. 35 of 2009 on narcotics, which includes provisions for the rehabilitation of individuals who abuse drugs. Rehabilitation is an effort to enable a person to function normally without addiction to addictive substances. One of the institutions that carries out rehabilitation related to addictive substances is the Sahabat Sehat Rekan Sebaya Jakarta Foundation. This foundation uses art therapy as a rehabilitation method. Therefore, the purpose of this study is to describe the art therapy process as a rehabilitation effort at the foundation. This study uses a descriptive qualitative approach with data collection through interviews, document reviews, and observations using purposive sampling as the informant selection technique. The results of this study show that the rehabilitation process begins with assessment, detoxification, and art therapy, both primary and re-entry, as well as aftercare or monitoring. The results show that rehabilitation using the art therapy method has successfully restored the physical, psychological, and social conditions of former drug users. They are physically fit, not easily tired, and able to control their sleeping hours. Psychologically, they are not anxious and are able to express themselves and their feelings through art, and socially, they began to reconnect with people they had previously cut off due to feelings of shame and lack of confidence.

Marriage is a basic human need that involves an official agreement between husband and wife, regulating rights and obligations, including the ownership and management of joint property. Under Indonesian law, property acquired during marriage is considered joint property, which often becomes a source of conflict during divorce. To prevent this, Indonesian law recognizes the existence of a marital separation of property agreement, which regulates the separation of assets between spouses from the beginning, whether before or during marriage. A separation of property agreement provides legal protection for personal assets, protects one party from being liable for the partner’s debts, and reduces the potential for disputes during divorce. Therefore, it is important for the public to receive socialization and legal education about the separation of property agreement in marriage to increase understanding of its benefits and protect the rights of married couples in both marriage and divorce. Legal education on this matter can help reduce disputes over joint property and offer better protection for couples who wish to clearly and legally manage their assets.

This research examines the implementation of the curator’s role in the bankruptcy process following the Postponement of Debt Payment Obligations (PKPU) based on Law Number 37 of 2004 concerning Bankruptcy and Postponement of Debt Payment Obligations. The main objective of this study is to analyze the role, authority, and challenges faced by curators in carrying out their duties in accordance with Indonesia’s positive legal framework. This research employs a normative juridical approach combined with an empirical juridical approach, incorporating a review of legal literature, court rulings, and statutory regulations, as well as interviews with curators and supervising judges in commercial courts. The findings reveal that curators play a central role as administrators and liquidators of bankrupt estates, with the authority to inventory, secure, manage, and liquidate the debtor’s assets to protect creditors’ interests. Pursuant to Law Number 37 of 2004, curators are also responsible for overseeing the bankruptcy process, preparing reports, and ensuring that the distribution of liquidation proceeds is conducted transparently and equitably. However, the implementation of this role often faces obstacles such as limited curator competence and resources, external interference, the complexity of bankruptcy laws, and inadequate judicial supervision. This study emphasizes the importance of legal reform, professional capacity building, and the adoption of digital technology to enhance the effectiveness of Indonesia’s bankruptcy system. A professional, accountable, and integrity-driven curator is essential to achieving the fundamental objectives of bankruptcy law—ensuring fair, efficient, and transparent debt settlement for all parties involved.

The pretrial institution serves to regulate the use of coercive measures by authorized organizations during the investigation and prosecution stages. The establishment of this institution is a primary priority aimed at protecting the rights of suspects, particularly in cases involving unlawful arrest or detention, the termination of investigations and prosecutions, and other similar circumstances. However, several weaknesses remain in both the design and implementation of this institution within the judicial system, resulting in insufficient protection of human rights for suspects, despite its regulation under positive law, namely Law Number 8 of 1981. Efforts to safeguard the human rights of suspects during the investigation process constitute the main focus of this study, which examines the legal status of pretrial procedures within Indonesia’s criminal justice system, the challenges in their implementation as a means of protection, the effectiveness of pretrial rulings in this context, and their implications for subsequent investigations.

PT. Tirta Fresindo Jaya, specifically its Pasuruan plant as the producer of Pucuk Harum Tea beverage, requires a large supply of steam to support various production processes. This steam is used in the process of heating tea leaves, heating water through a heat exchanger, and heating chemicals and water in the cleaning in place (CIP) process. Steam pressure of 5 bar that is flowed to the process equipment will undergo condensation to produce condensate. To separate steam and condensate, steam traps are used, consisting of several types, namely mechanical, thermostatic, and thermodynamic. However, in operational practice, steam trap malfunctions often occur, either in the form of steam leaks that are wasted with condensate or failure to drain condensate from the system. This condition causes a decrease in the efficiency of the steam piping system and increases the workload of the boiler. As a result, fuel consumption and boiler feed water requirements become greater than ideal conditions. Therefore, this study aims to analyze the energy and operational losses caused by steam trap malfunctions, as well as evaluate their impact on boiler system performance and steam utilization efficiency at PT. Tirta Fresindo Jaya Pasuruan plant.
