Abstract

Several factors that affect boiler efficiency in Palm Oil Mill are saturated pressure, feed water temperature, steam temperature, amount of steam produced, amount of fuel consumption, and calorific value of fuel combustion. The purpose of this study is to obtain the relationship between saturated pressure variations and boiler efficiency, the relationship between feed water temperature variations and boiler efficiency, the relationship between variations in the amount of steam produced and boiler efficiency, and to analyze the calorific value of 75% fiber fuel + 25% shell and Water Tube boiler efficiency. From the analysis results that have been carried out, it was obtained that the relationship between saturated pressure variations and boiler efficiency is not constant, but fluctuates. The relationship between feed water temperature variations and boiler efficiency shows an inconsistent pattern, while the relationship between variations in the amount of steam produced and boiler efficiency is relatively constant and increasing. The high combustion calorific value (HHV) is 21323.584 kJ/kg, and the low combustion calorific value (LHV) is 18083.584 kJ/kg. The highest boiler efficiency value produced is 68% and the lowest boiler efficiency value produced is 49%.

Abstract

Coconut plantations produce residue or waste that has not been utilized optimally. There are three types of waste produced by coconut plantations, namely solid waste, liquid waste and gas. One use of coconut solid waste is to use it as a renewable energy source or as an alternative fuel such as making charcoal briquettes. This potential illustration can be used as a waste processing innovation, which does not rule out the possibility of making society's economic cycle better. The aim of this research is to provide education to the people of Ujung Rambe Village, Bangun Purba District, Deli Serdang Regency about the use of coconut shell waste into charcoal briquettes. Providing education to the people of Ujung Rambe Village, Bangun Purba District, Deli Serdang Regency turns the process of making charcoal briquettes into a side income so that it can improve the community's economic benefits in daily life

Abstract

The problem identified in this study was the low level of students' collaboration skills and Mathematics learning outcomes among fourth-grade students at SDN SN Kebun Bunga 4 Banjarmasin. Students were less actively involved in learning activities, experienced difficulties in working collaboratively, and had not yet achieved the predetermined learning mastery criteria. This study aimed to improve students' collaboration skills and learning outcomes through the implementation of the Problem Based Learning (PBL) model. The study employed Classroom Action Research (CAR) conducted in three meetings. The subjects were 24 students of class IVA, consisting of 13 male and 11 female students. Data were collected through observation, tests, and documentation and analyzed using descriptive quantitative and qualitative methods. The results showed an improvement in students' collaboration skills and learning outcomes. Collaboration skills increased from 42% in the first meeting to 75% in the second meeting and 88% in the third meeting. Similarly, learning outcomes increased from 46% in the first meeting to 66% in the second meeting and 87.50% in the third meeting. Therefore, the implementation of the Problem Based Learning model improved students' collaboration skills and Mathematics learning outcomes.

Abstract

This article examines the issue of intellectual property rights (IPR) violations arising from the use of Artificial Intelligence (AI) in generating creative works. While AI technologies have advanced rapidly and are capable of producing outputs comparable to human creations, legal frameworks remain underdeveloped. Some jurisdictions restrict copyright ownership to humans, while others explore whether AI or its owners may hold rights. The Indonesian Copyright Law (Law No. 28/2014)¹ does not explicitly regulate AI-generated works, resulting in a legal vacuum. This study adopts a normative legal research method with statute, comparative, and case approaches to analyze Indonesia’s regulatory gaps alongside practices in the United States, European Union, and Japan. Findings show that Indonesian law remains limited to conventional notions of human authorship, while international cases such as Thaler v. Copyright Office² and Getty Images v. Stability AI³ illustrate ongoing disputes about AI creativity and copyright. The article contributes by proposing policy reforms in Indonesia, emphasizing the need for adaptive legislation, clearer liability mechanisms, and harmonization with global standards. Implications: Strengthening protection for creators, ensuring fair use of data in AI training, and advancing international dialogue on AI’s legal status.
