Abstract

The shipping industry faces significant challenges in reducing emissions and improving ship operational efficiency. This study aims to analyze the impact of environmentally friendly technology and renewable energy utilization on the operational efficiency of merchant vessels. The study was conducted at TUKS PT. Petrokimia Gresik using a quantitative approach by distributing questionnaires to 96 respondents, who were ship operators and technicians. Data were analyzed using multiple linear regression to test the partial and simultaneous effects of both independent variables on operational efficiency. The results of the study indicate that both environmentally friendly technology and renewable energy significantly influence ship operational efficiency, both partially and simultaneously. The coefficient of determination (R²) of 0.674 indicates that 67.4% of the variation in operational efficiency is explained by these two variables. This finding reinforces the urgency of implementing a green shipping strategy in the Indonesian maritime sector. This study suggests the need for continued investment in low-emission technologies and the use of alternative energy sources in industrial ports.

Abstract

Based on Law Number 27 of 2007 Jo. Law Number 1 of 2014 Concerning Management of Coastal Areas and Small Islands, the Government has the rights and controls. Regional governments, districts/cities have the responsibility to make plans for regulations or decisions in the management and utilization of resources for the benefit of the community. The issuance of land rights certificates on sea waters has a complicated background, involving legal aspects, regulations, and practices. In general, the sea is part of the natural resources controlled by the state, so it cannot be directly certified as land rights. However, there are exceptions for buildings or constructions built on waters, which can have land rights. The formulation of the problems discussed are: 1) What are the legal basis and legal considerations in issuing land title certificates with objects located above sea waters? and 2) How is the validity of land title certificates issued without meeting the requirements in the Complete Systematic Land Registration (PTSL)? The research method used is the normative touristic method, namely research that prioritizes library data, namely research on secondary data. The secondary data can be in the form of primary, secondary or tertiary legal materials. Based on the results of the study, the author concludes that the legal basis and legal considerations in issuing land title certificates with objects located above sea waters have a complex legal basis and require careful legal considerations. In general, land rights on land and at sea have different regulations, with the sea being considered a public space controlled by the state. Issuance of certificates for objects in sea waters often requires adjustments to regulations on licensing activities in sea space and considering the basic principles of agrarian law, namely: a) Basic Agrarian Law (UUPA); b) Law No. 27 of 2007 concerning Management of Coastal Areas and Small Islands; c) Government Regulation (PP) related to Sea Space; and d) Government Regulation No. 24 of 1997 concerning land registration. While the legal considerations are: a) Nationality Principle; b) State Control Rights; and c) Application of the HGB Principle (Building Use Rights) or Usage Rights.

Abstract

In the process of providing health services, errors or negligence can occur in the form of patient identification errors either in the process of diagnosis, treatment, or other medical procedures. Such negligence or error can potentially result in injury or loss to the patient. The purpose of providing correct patients identification is to identify patients who will be given appropriate services, actions, or treatment. One of the vulnerabilities of services for newborns is the error of health workers in providing identification. Newborn babies must be matched with the mother who gave birth to them, namely immediately attaching an identity bracelet immediately after the baby is born to avoid the baby being exchanged. The formulation of the problems discussed are: 1) How is the mechanism and verification of the identity of babies born in hospitals to prevent cases of baby exchange? and 2) What is the form of legal responsibility of the hospital if there is a case of baby identity exchange according to laws and regulations in the context of legal certainty? The research method used is the normative juridical method, namely the research is conducted with a literature approach, namely by studying books, laws and regulations and other documents related to this research. Based on the results of the study, the author concludes that the legal responsibility of the hospital in the event of a case of a baby's identity being exchanged according to laws and regulations in the context of legal certainty is that the hospital can be held accountable for criminal, civil, state administration, and professional ethics or for negligence that results in losses for patients and families. Referring to the provisions of Article 46 of Law Number 44 of 2009 concerning Hospitals, it states that: the hospital is legally responsible for all losses caused by negligence by health workers in the hospital. In an effort to hold the hospital criminally responsible, it was first started by providing a number of compensation, and/or compensation, of course the hospital must sit down together with the policy makers of the hospital.

Abstract

One form of unlawful acts that often occur in the development of technology and information in this digital era, is defamation or insults committed through social media. Defamation through social media is included in the category of cyber criminal acts regulated in Article 27 paragraph (3) of the ITE Law which reads: "every person deliberately and without the right distributes and/or makes accessible electronic information and/or electronic documents that have insulting and/or defamatory content. The formulation of the problem discussed is: 1) How to regulate alleged defamation through social media? and 2) How is the application of criminal sanctions against perpetrators of criminal acts that are proven to be defamatory through social media that cause harm to others?. The research method used is the normative juridical method, namely research that prioritizes literature data, namely research on secondary data. The secondary data can be in the form of primary, secondary or tertiary legal materials. Based on the results of the research, the author concludes that the application of criminal sanctions against perpetrators of criminal acts that are proven to be defamatory through social media that causes harm to others, is regulated in the ITE Law and the Criminal Code. Perpetrators can be subject to imprisonment and fines, with heavier penalties if carried out through social media because of its wider and fast-spreading impact. Defamation through social media is included in cyber crimes and is regulated in Article 27 paragraph (3) of the ITE Law which reads: "Every person deliberately and without the right to distribute and/or transmit and/or make accessible Electronic Information and/or Electronic Documents that have insulting and/or defamatory content. However, in the decision of the Central Jakarta District Court Number 589/Pid.Sus/2024/PN Jkt.Pst, the defendant was declared not legally and convincingly proven guilty of committing the criminal act as charged, thus acquitting the Defendant therefore from all charges of the Public Prosecutor.

Abstract

This study investigates the application of machine learning techniques for predictive maintenance in industrial rotating machinery, with a specific focus on bearing fault detection. Utilizing a qualitative research approach, the study synthesizes existing literature, industry case studies, and experimental findings to provide a comprehensive analysis of data-driven maintenance practices. Vibration signal analysis, particularly using frequency domain features extracted through Fast Fourier Transform (FFT), forms the basis for fault diagnosis. Machine learning models such as Support Vector Machines (SVM) and ensemble classifiers are examined for their effectiveness in early detection of bearing faults. The results highlight that these models achieve fault identification accuracies exceeding 90%, enabling timely interventions that reduce unplanned downtime and maintenance costs. The qualitative insights also emphasize integration with Industry 4.0 technologies like IoT and cloud computing, which enhance real-time monitoring capabilities and scalability of predictive maintenance systems. Challenges, including data quality issues and environmental noise, are discussed alongside future directions for algorithm refinement and broader fault detection. Overall, this study underscores the value of machine learning-based predictive maintenance as a transformative approach for improving reliability and operational efficiency in industrial rotating machinery.
