Abstract

The problem of fossil energy crisis and the increasing carbon emissions have encouraged the search for environmentally friendly alternative energy sources, one of which is through the utilization of biomass into solid fuels such as bio-char. This study aims to optimize the pyrolysis process conditions to produce high-quality bio-char from Acacia crassicarpa bark, a lignocellulosic waste from the forestry industry. The pyrolysis process was carried out in a batch reactor with variations in temperature (400–500°C), residence time (30–60 minutes), and NiMo/NZA catalyst concentration (2–6%) as independent variables. Optimization was carried out using the Response Surface Methodology approach with a Central Composite Design experimental design to obtain the optimum conditions. The results showed that the optimum conditions were obtained at a pyrolysis temperature of 400°C, residence time of 30 minutes, and catalyst concentration of 2%, resulting in a bio-char yield of 33.8% with a desirability value of 0.876. Meanwhile, the highest calorific value of 28 MJ/kg was achieved at the same temperature with a residence time of 90 minutes. This value exceeds the minimum standard for solid fuels according to the International Biochar Initiative and the European Biochar Certificate, which are generally in the range of >20–25 MJ/kg. Thus, the resulting bio-char not only has potential as an alternative energy source but also meets quality standards as an efficient and sustainable solid fuel.

Abstract

This article describes problem-based mathematics learning in elementary schools. The description begins with the concept of mathematics learning, the concept of problem-based learning and the steps of problem-based learning. The main part of this article is a discussion of problem-based learning in mathematics implemented in the fourth grade of SDN Antasan Besar 1 Banjarmasin. The implementation of the Problem-based learning model includes orientation to the problem, organizing students, guiding investigations, developing and presenting results and analyzing and evaluating the process and results of problem solving. Based on the results of the learning analysis carried out, it shows that problem-based mathematics learning goes well in elementary schools, problem-based mathematics learning can improve the quality of learning and improve student learning outcomes in elementary schools. Based on the results of the study, problem-based learning in mathematics is highly recommended in grade four elementary schools.

Abstract

The enactment of Presidential Instruction Number 1 of 2022, on Optimizing the Implementation of the National Health Insurance Program, introduces a requirement for proof of National Health Insurance (BPJS Kesehatan) participation from all citizens during land rights transfers. This study examines the legal implications of this instruction, focusing on its validity, relevance, and social impact on public access to land rights. Employing a doctrinal approach, the research involved legal document reviews, policy analysis, and interviews with relevant stakeholders. The findings indicate that mandating BPJS membership as a condition for land transfer registration is legally invalid, irrelevant, and conflicts with Indonesias constitutional hierarchy. This inconsistency leads to legal uncertainty and undermines the principle of orderly regulation, creating overlapping regulations, unclear authority between the National Land Agency (BPN) and BPJS Kesehatan, and potential institutional conflicts. It increases administrative burdens that could restrict citizens access to legitimate land rights. Overall, the study argues that this instruction risks undermining legal hierarchy and good governance principles, which could adversely affect public access to land and hinder effective policymaking. It highlights the importance of understanding Indonesias legislative hierarchy to prevent policies from disrupting existing legal structures. To mitigate these issues, it is recommended that the government revise Presidential Instruction Number 1 of 2022, ensuring alignment with legislative hierarchy, and foster dialogue and collaboration among relevant institutions for the development of comprehensive, non-conflicting policies.

Abstract

Dancers’ makeup in a performance is an attraction for the community of connoisseurs and observers of the Ebeg. The Mega Laras group in Tanjunganom, Rakit, Banjarnegara was plagued by problems with the makeup of its performers in staging performances, caused by the lack of knowledge and skills of the dancers and makeup artists. With full support from the village government and all group members to conserve Ebeg as an Indonesian cultural heritage, Universitas Negeri Semarang through its community service team provided a solution through facilitation-based action learning model training. The purpose of this activity was to improve the makeup skills of the group members, with main stages of implementation of preparation, training, and result analysis. The preparation included coordinating with partners about the place and time of the activity, and team coordination regarding technical implementation. The training phase included planning, workshop, and mentoring. During the training, a set of tools and makeup materials were distributed to partner. Analysis of the overall activity showed that 80% of participants demonstrated significant skill improvement after the training. The community service activity supports Sustainable Development Goal (SDGs) 4, namely Quality Education, for providing lifelong learning opportunities for the traditional arts practitioners.
Lingkungan Pergaulan (Social Circle) sebagai Determinan Perkembangan Individu: Tinjauan Integratif dari Perspektif Psikologi, Agama Islam, dan Ilmu Sosial Sirojudin, Sirojudin; Idwar, Agus; Yasin, Rahman; Sunarno, Sunarno; Salsabila, Alifa Sauda

Abstract

Tujuan penelitian ini adalah untuk menganalisis pengaruh lingkungan pergaulan (social circle) terhadap perkembangan individu melalui pendekatan integratif multidisiplin. Metode yang digunakan adalah kajian pustaka sistematis dengan mengeksplorasi perspektif Psikologi Sosial, Agama Islam (dalam Al-Qur'an, Hadis, dan Tasawuf), Sejarah, dan Filsafat. Hasil analisis menunjukkan konvergensi yang signifikan antar disiplin ilmu mengenai kekuatan determinan lingkungan sosial. Dalam psikologi, teori Social Learning dan Conformity menjelaskan mekanisme peniruan dan penyesuaian diri. Agama Islam menegaskan hal ini melalui hadis Nabi tentang analogi penjual minyak wangi dan pandai besi, serta konsep ukhuwah. Tasawuf menekankan peran "Sohbet" (pergaulan dengan orang shaleh) untuk transfer cahaya spiritual (nur). Sejarah membuktikan melalui kelompok Renaissance dan halaqah sahabat Nabi bagaimana circle membentuk peradaban. Filosofi Aristoteles tentang "zoon politikon" memperkuat dasar manusia sebagai makhluk sosial. Simpulan penelitian ini adalah bahwa lingkungan pergaulan bukan hanya faktor pendukung, melainkan determinan fundamental yang mempengaruhi pola pikir, kebiasaan, ketahanan mental, standar hidup, dan arah masa depan individu. Implikasinya, intervensi melalui pembinaan komunitas positif (seperti halaqah dalam Islam) perlu menjadi strategi utama dalam pendidikan, dakwah, dan pengembangan masyarakat.
