The increasing volume of hazardous and toxic waste (B3), particularly from used cooking oil, poses significant environmental and health challenges. One promising solution is converting this waste into biodiesel, thereby promoting renewable energy development while reducing ecological risks. This study investigates the yield percentage of biodiesel produced from waste cooking oil using a magnetic stirrer. The research aims to determine the optimal stirring duration to maximize yield and evaluate the flame duration of the resulting biodiesel. The process involved tool and material preparation, biodiesel production via transesterification, and subsequent data collection and analysis. The findings revealed that the highest biodiesel yield, 58.4%, was achieved at a stirring duration of 45 minutes, whereas the lowest yield, 51.2%, occurred at 60 minutes.

The increasing consequences of global climate change underscore the necessity for the integration of low-carbon education and renewable energy frameworks within the educational paradigm for learners. This study develops a training curriculum for Youth Scientific Paper/Karya Ilmiah Remaja (KIR) that incorporates these principles to enhance students' scientific proficiency. Utilizing a Systematic Literature Review (SLR) approach, thirty indexed scholarly articles from the last decade were rigorously analyzed. The results reveal that the inclusion of low-carbon education and renewable energy within KIR training programs significantly improves students' abilities in critical thinking, problem-solving, and data analysis while concurrently fostering environmental awareness. Effective implementation strategies include project-based learning, hands-on renewable energy experiments (such as solar panels and wind turbines), and collaborations with environmental organizations. However, challenges such as limited resources, insufficient mentor training, and inadequate policy support hinder successful implementation. Despite these obstacles, the integration of low-carbon education and renewable energy within KIR initiatives holds substantial promise for cultivating environmentally responsible scientific skills among students. This initiative aligns with the Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education), SDG 7 (Affordable and Clean Energy), and SDG 13 (Climate Action), thus contributing to a more sustainable future.

This research aims to explore the potential implementation of restorative justice in the resolution of press offense disputes in Indonesia, with a focus on Law No. 40/1999 on the Press. The urgency of this research arises from the need to reduce the burden on the increasingly heavy judicial system and increase the effectiveness of media dispute resolution. In this context, restorative justice can be a more humane and efficient alternative to conventional litigation approaches. The scope of the problem includes the lack of regulations supporting restorative mechanisms in the Press Law, as well as practical challenges in implementing mediation in Indonesia. The main findings show that restorative justice can help restore social relations between the parties involved, in a more constructive way, rather than simply imposing punishment. The novelty of this research lies in identifying the potential application of restorative justice in the context of press disputes, as well as the role of the Press Council as a mediator in dispute resolution mechanisms. The method used in this research is legal analysis and comparison of legal systems in other countries, as well as a study of restorative justice theory and its application in press disputes in Indonesia.

Abstract
 
This article aims to analyze the existence and reformulation of appropriate legal policies towards Law Number 19 of 2019 on the Corruption Eradication Commission, in combating corruption. The symbolic action taken by numerous anticorruption activists in the context of the funeral of the Corruption Eradication Commission (KPK) due to the ratification of Law No. 19/2019 reflects the integrity crisis of the institution. Several rules that have become polemic, namely the KPK's status as a State Institution, KPK’s status staff as a State Civil Apparatus, the presence of the Supervisory Board, and the rules regarding the Termination of Investigation and Prosecution. By applying the normative juridical research method, this study intends to provide a reformulation model for Law No.19/2019. Apart from not fulfilling all the principles in the Law on the Establishment of Legislation, which makes this regulation formally flawed, several articles in it can also harm KPK, some of those articles have been declared unconstitutional and conditionally unconstitutional based on the Constitutional Court's decision. Therefore, the implementation of reward and punishment within the KPK, along with personal evaluations supported by reverse proof of assets owned, should be an effective input for KPK to become a better institution.
 
Artikel ini bertujuan untuk menganalisa eksistensi dan reformulasi kebijakan hukum yang tepat terhadap Undang-Undang Nomor 19 Tahun 2019 tentang Komisi Pemberantasan Korupsi, dalam rangka memperkuat pemberantasan korupsi. Tindakan simbolis yang dilakukan oleh sejumlah pegiat antikorupsi dalam rangka pemakaman Komisi Pemberantasan Korupsi (KPK) akibat pengesahan UU No. 19/2019 mencerminkan adanya krisis integritas pada lembaga tersebut. Beberapa aturan yang menjadi polemik, yaitu status KPK sebagai Lembaga Negara, status kepegawaian KPK sebagai Aparatur Sipil Negara (ASN), hadirnya Dewan Pengawas (Dewas), dan adanya aturan mengenai Penghentian Penyidikan dan Penuntutan. Dengan menerapkan metode penelitian yuridis normatif, studi ini hendak memberikan model reformulasi terhadap UU No.19/2019. Selain dari tidak terpenuhinya seluruh asas-asas dalam Undang-Undang Pembentukan Peraturan Perundang-Undangan yang menjadikan peraturan ini cacat formil, beberapa pasal di dalamnya juga dapat merugikan KPK, di mana sebagian telah dinyatakan inkonstitusional dan inkonstitusional bersyarat berdasarkan putusan Mahkamah Konstitusi. Sehingga dengan ikut diterapkannya reward and punishment dalam lingkup KPK, juga evaluasi personal dengan pembuktian terbalik mengenai harta kekayaan mereka, seharusnya menjadi masukan yang efektif bagi KPK untuk dapat menjadi institusi yang lebih baik lagi.

This study aims to examine the legal status of land rights that can be owned by transmigration communities and the legal protection that can be taken by the community if they feel disadvantaged. The research method used is normative legal research using a statutory approach and a case approach. The government is holding a transmigration program for population equality throughout Indonesia, therefore, a transmigration area was formed as a residential area and a place of business for the community to improve the community's standard of living. Over time, the need for land has increased because community growth is not comparable to the available land, so it often causes disputes. One example of a land dispute that occurs is transmigration land owned by the community that has changed ownership to company land, where the transmigration land owned by the company was obtained by winning an auction. This study was conducted to determine the appropriate legal system in resolving transmigration land disputes whose land is used as an auction object, as well as to find out about the legal protection received by transmigration communities. The results of the study are that the legal status of transmigration land that is used as an auction object should still belong to the transmigration community because transmigration land cannot be transferred, while legal protection for transmigration communities should mean that the land is not used as an auction object by the local government because it still belongs to the transmigration community.

This study aims to analyze the application of chemical castration against perpetrators of child sexual abuse from a human rights (HR) perspective and examine the legal considerations in the District Court Decision of Banjarmasin Number 858/Pid.Sus/2022/PN.Bjm. Child sexual abuse is a serious crime that causes long-term physical and psychological harm. The Indonesian government responded by enacting chemical castration sanctions under Law Number 17 of 2016 and Government Regulation Number 70 of 2020. The research method used is normative juridical with statutory and conceptual approaches, and qualitative analysis of primary and secondary legal materials. The results show that the implementation of chemical castration has the potential to conflict with the principle of non-degrading treatment under international human rights instruments ratified by Indonesia. The novelty of this study lies in its evaluative approach, combining national legal norms, international HR standards, and actual judicial practice. It concludes that chemical castration may be maintained if it meets medical consent, strict supervision, and protects the rights of offenders. The study recommends a policy reform focusing on offender rehabilitation, public education, and independent oversight to ensure comprehensive rights protection.
 
Kekerasan seksual terhadap anak merupakan kejahatan serius yang menimbulkan dampak fisik dan psikologis jangka panjang. Pemerintah Indonesia merespons kejahatan ini dengan memberlakukan sanksi kebiri kimia melalui Undang-Undang Nomor 17 Tahun 2016 dan Peraturan Pemerintah Nomor 70 Tahun 2020. Penelitian ini bertujuan untuk menganalisis penerapan sanksi kebiri kimia terhadap pelaku kekerasan seksual anak dalam perspektif hak asasi manusia (HAM), serta mengkaji pertimbangan hukum dalam Putusan Pengadilan Negeri Banjarmasin Nomor 858/Pid.Sus/2022/PN.Bjm. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan dan konseptual, serta analisis kualitatif terhadap bahan hukum primer dan sekunder. Hasil penelitian menunjukkan bahwa penerapan kebiri kimia berpotensi bertentangan dengan prinsip non-degrading treatment dalam konvensi internasional yang telah diratifikasi Indonesia. Novelty dari penelitian ini terletak pada pendekatan evaluatif yang menggabungkan analisis norma hukum nasional, HAM internasional, serta praktik yudisial konkret. Disimpulkan bahwa kebiri kimia dapat dipertahankan dengan syarat adanya persetujuan medis, pengawasan ketat, dan perlindungan terhadap hak pelaku. Rekomendasi yang diajukan meliputi reformulasi kebijakan dengan menekankan rehabilitasi pelaku, edukasi publik, serta pengawasan independen untuk menjamin perlindungan hak semua pihak yang terlibat.
