Plastic waste has become one of the main environmental problems due to its nature, which is difficult to decompose naturally and can cause environmental pollution. One alternative waste treatment method that can be applied is to use a plastic melter to melt and recycle plastic waste into useful products. However, the design of plastic melters often lacks consideration of structural strength and safety aspects during the operation process. This study aims to design and engineer a plastic melter using the Finite Element Analysis (FEA) simulation approach to analyze structural resistance to thermal and mechanical loads that occur during the operation process. The research method was carried out through 3D design modeling of plastic melter components using Solidworks software, followed by analysis with FEA simulation on the main component, namely the melting tube. The parameters analyzed include the distribution of von Mises stress, the amount of displacement, and the safety factor. The analysis results show that the analyzed components experience von Mises stress distribution and displacement that are still below the material tolerance limits, with safety factor values above the recommended safety limits. Thus, the resulting plastic melter design is declared safe and can proceed to the manufacturing process. Therefore, the plastic melter design is safe, strong, and feasible to be realized as an effective and sustainable plastic waste processing technology solution.

Academic stress is a psychological pressure commonly experienced by final-year university students, particularly during the process of completing their undergraduate thesis. High academic demands, limited time, pressure to graduate on schedule, and various obstacles encountered during research may intensify students’ emotional burden. When left unmanaged, academic stress can escalate into more serious psychological problems, including suicidal ideation. This study aims to analyze the relationship between academic stress levels and suicidal ideation among final-year students at Universitas Islam Sultan Agung Semarang. This research employed a quantitative design with a cross-sectional approach. A total of 180 respondents were selected using a simple random sampling technique. The research instruments consisted of the Perceived Academic Stress (PAS) scale to measure academic stress levels and the Adult Suicidal Ideation Questionnaire (ASIQ) to assess suicidal ideation. Data analysis was conducted using the Spearman Rank correlation test. The results showed that the majority of students experienced high (49.4%) and very high (47.8%) levels of academic stress. Meanwhile, suicidal ideation was most commonly found in the mild category (42.8%), followed by the no-risk category (28.9%). The statistical test indicated a significance value of p = 0.021 with a correlation coefficient of r = 0.172, demonstrating a positive and significant relationship between academic stress and suicidal ideation. These findings indicate that higher levels of academic stress are associated with an increased likelihood of suicidal thoughts among final-year students. The study highlights the importance of mental health support, academic guidance, and accessible counseling services to mitigate psychological distress and reduce the risk of suicidal ideation during the thesis completion period.

The family is the smallest unit in society, within which rights and obligations exist as in social life in general. In fulfilling individual needs and interests, conflicts often arise, including disputes over inheritance distribution. Inheritance refers to the property left behind by a deceased person, which must be distributed to entitled heirs in accordance with Islamic law or customary law applicable within the community. Problems frequently emerge regarding the position of substitute heirs, particularly nephews, within the Islamic inheritance system. This study entitled “Various Aspects of Family Law in Indonesia: The Problematics of the Position of Nephews as Substitute Heirs in Islamic Law” aims to examine the status of substitute heirs in inheritance distribution and to identify the conditions under which substitute heirs are recognized in Islamic law. The research employs a normative method with a library-based approach, analyzing classical fiqh literature and scholarly opinions. The data consist of primary and secondary sources collected through document study. The findings indicate that a substitute heir is recognized when the primary heir dies after the testator but before the inheritance has been distributed, allowing the substitute heir to receive the share in accordance with Islamic legal provisions.

Low levels of maternal knowledge and appropriate nutritional practices, combined with limited continuity of nutrition education from health workers, remain significant risk factors for maternal and child health problems, including stunting.

In the modern era, embedded systems and the Internet of Things (IoT) are experiencing rapid and continuous development, with their usage projected to match or even exceed the number of IoT devices globally. This technological transformation has influenced various sectors, including education, which must adapt to current digital advancements. Therefore, it is important for educational institutions to integrate embedded systems and IoT concepts into their curricula to ensure that learning remains relevant to industrial and technological demands. Improving the competence and technological literacy of students and lecturers in the fields of embedded systems and IoT, particularly for smart control applications, is expected to strengthen academic capabilities and practical skills. Through this development, higher education institutions can encourage innovation and the application of technology-based solutions in solving real-world problems. Furthermore, this effort supports the implementation of the Tri Dharma of Higher Education, especially in the areas of education and research, by promoting applied research projects and collaborative learning activities based on embedded systems and IoT technologies.

The industrial revolution 4.0 has brought rapid advances in technology, one of which is artificial intelligence (AI). AI has the ability to imitate the human thought and action process in solving various problems. However, the implementation of AI raises legal problems related to responsibility for the negative impacts caused, such as cybercrime, information manipulation, privacy violations, and misuse of technology. Indonesia, as a country based on law, is faced with the challenge of regulating AI to be in line with technological developments. Currently, legal regulations in Indonesia do not specifically regulate the legal responsibility of AI. Positive laws, such as the Civil Code and the ITE Law, can be used interpretively, but are not enough to address the complexity of AI. Legal responsibility related to AI is debatable, whether it is imposed on the developer, owner, or user of AI. In addition, AI does not have a “mens rea” in criminal law, so that unlawful acts are more relevant to be imposed on the responsible human. To overcome this problem, legal reform or the creation of special regulations that comprehensively regulate AI are needed. These regulations must include privacy protection, data security, and criminal and civil liability due to the use of AI. With a clear legal framework, the risk of AI misuse can be minimized and its use can be optimized for the welfare of society.

This research is based on the shortage of functional penghulu officers, which has become a serious issue for the government, particularly the Ministry of Religious Affairs of Indonesia. This condition can affect the quality of services in marriage registration, family guidance, and the provision of legal certainty to the community. To overcome the emergency of penghulu personnel, it is necessary to propose that the position of penghulu also be granted equal access to women, whereas until now the position of penghulu has been dominated only by men. Therefore, this research aims to conduct a comprehensive study on the provisions regarding the opportunities and problems of female penghulu within Indonesia’s civil law system, in which civil law is the official positive legal umbrella governing penghulu affairs. This research is normative legal research employing a statutory approach and a conceptual approach. Meanwhile, the primary legal materials of this research consist of various laws and regulations directly related to penghulu affairs. The results of this research indicate that the opportunities for female penghulu within the civil law system are very open, constitutionally valid, and not subject to any normative prohibition. The problems arise when female penghulu are requested to act as guardians appointed by the court (wali hakim) or entrusted with the delegated guardianship of marriage (taukil wali). This is because, under Indonesia’s civil law, a wali hakim or a person receiving taukil wali is required to be male. In addition, another problem is the existence of a specific requirement to be male that must be fulfilled in the recruitment of penghulu personnel as stated in the Announcement Letter on the Recruitment of Candidates for Civil Servants of the Ministry of Religious Affairs.  

Adolescence has problems, one of which is reproductive health. Factors that influence reproductive health include socioeconomic and demographic factors, cultural and environmental factors, psychological factors, and biological factors. This study aims to determine the factors related to the reproductive health of adolescents at SMPN 3 Pantai Raja, the working area of the UPT Pantai Raja Health Center (respondent characteristics, parental characteristics, adolescent knowledge, family support). This type of research is descriptive with a cross- sectional approach. The population is all seventh grade students at SMPN 3 Pantai Raja, the working area of the UPT Pantai Raja Health Center, grade VII in October 2025 with a sample of 59 people using total sampling. Data analysis uses descriptive data analysis and statistic chi square, namely explaining data about each variable. The results of the study showed that all (100%) were in the 35-49 age group, the majority (57.6%) had secondary education, the majority (59.3%) were employed, the majority (71.1%) had sufficient support, all (100%) were aged 11-14 years, almost all (81.4%) were female, and the majority (57.6%) had sufficient knowledge. The conclusion of this research is that there is a relationship between knowledge and support from parents of class VII students with a p-value of 0.001 and factors related to adolescent reproductive health influence each other to influence reproductive health during adolescence. Therefore, it is hoped that community health centers will increase knowledge and understanding, especially in providing services to adolescents, to provide more information about adolescent reproductive health.
