Briquettes are a type of alternative energy whose raw material source comes from agricultural waste such as coconut shells. Coconut shells are converted into charcoal which has a higher calorific value through the pyrolysis process. The aim of this research is to determine the effect of comparing particle size and printing pressure on the length of burning time and burning temperature, so as to obtain a briquette composition that is durable and produces high temperatures. In this research, the raw material used was shell waste with a drying process of 400°C and the particle size variations used were mesh 30, 150 and 250 mixed with 12 grams of starch adhesive. The briquette molding process uses 3 kg and 5 kg pressure, which are then dried using an oven at a temperature of 750°C for 3 hours. Tests were carried out on burning time, burning temperature, water content and ash content. From the research results, it was found that for the highest temperature, briquettes with a particle size of 250 mesh were produced with a pressure of 5 kg at 312°C, and the flame duration of the briquettes was 240 minutes.

Briquettes are a type of alternative energy whose raw material source Plastic waste is an environmental problem faced by the people of Indonesia and the world. On the other hand, the production of waste generated in various institutions and sectors in Indonesia continues to increase every year, including the industrial sector whose production process is large-scale. Its use as a basic material for packaging bottles reaches 30% of world use. PET is also used as a synthetic fiber or polyester which accounts for 60% of world use. Study the author will do that is to make a tubing made from PET plastic waste that can be used as raw material for tubing. Using temperature variations (190?, 200?, 210?), then 9 samples from each variation will be micro-photographed the effect of temperature on tubing results and tested for maximum tensile. After that, calculations are carried out to obtain the maximum tensile stress and strain values. Then the average maximum load value that can be received by PET tubing is highest at 190ºC temperature tubing has the ability to withstand tensile strength better than all temperature variations so that the average value is 35.94 N/mm2 and 200ºC is able to withstand 35.49 N/mm2 and 210ºC with 18.30 N/mm2. It can be interpreted that the higher the temperature, the effect on holding the tensile strength of the PET tubing and making the plastic structure change so that 210oC is close to the recycling value, while for temperatures below it is still non-recycled.

Divorce is a global phenomenon with significant implications for children's rights. This study aims to conduct a comparative analysis of the fulfillment of children's rights after divorce in five countries with different legal systems: Qatar, Egypt, Indonesia, Malaysia, and Jordan. The research employs a normative juridical method with a comparative legal research approach through literature review and legal document analysis. The findings reveal that each country has a unique mechanism for ensuring children's rights after divorce. Diverse legal systems—ranging from common law, civil law, to Islamic law—lead to variations in approaches to ensuring custody, care, and protection for children. The study identifies four critical dimensions in fulfilling children's rights: the right to survival and development, the right to protection, the right to education, and the right to participation. The comparative analysis highlights that cultural factors, legal systems, and political commitment play a fundamental role in determining the effectiveness of child rights protection after divorce. Key recommendations of this study include the need for regulatory harmonization, strengthening enforcement mechanisms, and developing sustainable monitoring systems. This research provides theoretical and practical contributions to understanding the complexity of fulfilling children's rights across global legal systems.

The implementation of AI in the criminal justice system can enhance efficiency, transparency, and fairness in legal decision-making by efficiently managing information and providing legal considerations based on objective data. In Indonesia, although the Supreme Court has initiated technology-based innovations such as e-Court and Smart Majelis and is considering the concept of AI Judges, technical, legal, and ethical challenges must still be carefully addressed. The application of AI must take into account the specific aspects of Indonesia's legal system, ensure algorithmic transparency, and protect human rights. This research employs a doctrinal (normative) legal approach, utilizing legal materials including primary, secondary, and tertiary sources. The approaches used are the conceptual approach, comparative approach, and futuristic approach. The nature of the research is descriptive-prescriptive, and the data analysis method employed is content analysis. The results of the research indicate that the application of AI in Indonesia’s judiciary has significant potential to improve efficiency and justice, but must be done cautiously and wisely. AI should be used as a supportive tool for human judges, rather than fully replacing them. The concept of AI Judges, where AI plays a role in legal decision-making, must be accompanied by regulations that ensure transparency, accountability, and the protection of human rights. With a careful and ethical approach, AI can be a significant innovation in the judicial system, helping to achieve faster, simpler, and more efficient justice in line with the fundamental legal principles of Indonesia and the values of Pancasila.

Based on Article 351 (Paragraph 1) of the Criminal Code on ordinary persecution where in this article persecution is divided into three parts, namely ordinary, mild and severe persecution as in the case that I took to make this thesis with case number 2/Pid.B/2019/PN. In this case, the panel of judges sentenced the perpetrator of persecution to 10 months imprisonment, while the sentence that should have been imposed on the perpetrator of ordinary persecution was 2 years and 8 months by considering various kinds of evidence and factors of persecution, This study aims to analyze cases of persecution that refer to Article 351 of the Criminal Code (KUHP) in Indonesia.  In this analysis, we identify the elements necessary to determine whether an act can be classified as maltreatment under Article 351 of the Criminal Code.  This research involves a case study and analysis of the Depok district court decision, as well as referring to applicable laws and regulations.  The results of this analysis may provide a better understanding of the application of Article 351 of the Criminal Code in cases of maltreatment and its implications for the criminal justice system in Indonesia.
