Abstract

Penelitian ini mengeksplorasi peran filosofi Tri Hita Karana (THK) sebagai kerangka kerja untuk menciptakan harmoni dalam kehidupan masyarakat dan institusi di Bali. Dengan menggunakan tinjauan pustaka sistematis berbasis pedoman PRISMA, penelitian ini menganalisis 30 artikel yang relevan dari tahun 2014 hingga 2024. Hasil penelitian menunjukkan bahwa THK memainkan peran signifikan dalam berbagai aspek kehidupan, termasuk hubungan spiritual dengan Tuhan (parhyangan), interaksi sosial (pawongan), dan pelestarian lingkungan (palemahan). Filosofi ini tidak hanya mendukung harmoni sosial dan budaya melalui kegiatan kolektif seperti gotong royong dan pelestarian adat, tetapi juga menjadi pedoman dalam praktik keberlanjutan lingkungan. Pada tingkat institusi, THK diadopsi dalam kebijakan pemerintah, pendidikan, dan pariwisata, menghasilkan keseimbangan antara pembangunan ekonomi, pelestarian budaya, dan konservasi lingkungan. Meski demikian, tantangan dalam implementasi THK mencakup tekanan globalisasi, individualisme, dan modernisasi yang dapat mereduksi nilai-nilai tradisional. Penelitian ini memberikan kontribusi dengan mengidentifikasi praktik terbaik dalam penerapan THK serta relevansinya dalam konteks global. Implikasi praktis dari penelitian ini mencakup pengembangan kebijakan berbasis THK, penguatan strategi pendidikan, dan model keberlanjutan institusi yang menekankan keterpaduan antara nilai tradisional dan inovasi modern. Hasil ini mempertegas bahwa THK bukan sekadar filosofi lokal, melainkan pendekatan universal yang relevan untuk mendukung pembangunan berkelanjutan dan harmoni sosial di era modern. The Role of Tri Hita Karana in Community and Institutional Life: A Comprehensive Literature ReviewAbstractThis study explores the role of the Tri Hita Karana (THK) philosophy as a framework for fostering harmony in community and institutional life in Bali. Using a systematic literature review guided by PRISMA protocols, the research analyzes 30 relevant articles published between 2014 and 2024. The findings demonstrate that THK plays a significant role across various aspects of life, including spiritual connections with God (parhyangan), social interactions (pawongan), and environmental preservation (palemahan). This philosophy not only promotes social and cultural harmony through collective activities such as communal work (gotong royong) and cultural preservation but also serves as a guideline for environmental sustainability practices. At the institutional level, THK is adopted in government policies, education, and tourism, creating a balance between economic development, cultural preservation, and environmental conservation. However, challenges in implementing THK include pressures from globalization, individualism, and modernization, which can erode traditional values. This study contributes by identifying best practices in applying THK and highlighting its relevance in a global context. The practical implications of this research include the development of THK-based policies, the strengthening of educational strategies, and institutional sustainability models that emphasize the integration of traditional values and modern innovation. These findings underscore that THK is not merely a local philosophy but a universal approach relevant to supporting sustainable development and social harmony in the modern era.

Abstract

Educational philosophy plays a dominant role in shaping educational theory and practice by providing an epistemic and ethical foundation. This study examines recent literature (2023-2024) to analyze how philosophical concepts, such as Kuhn’s paradigm shifts and culturally rooted approaches like Ubuntu and Ujamaa, influence curriculum design and teaching methods. Using the PRISMA systematic review method, this research identifies 35 relevant documents and conducts an in-depth analysis of 13 journal articles discussing the role of philosophy in education. The findings indicate that philosophy contributes to enhancing critical literacy, epistemic decolonization, and strengthening inclusive educational strategies. This study also highlights the challenges in applying philosophical principles in global education systems, which are still predominantly influenced by Western-based curricula. Through a comprehensive literature review, this research asserts that educational philosophy is not only of academic value but also has practical implications for improving the relevance and quality of education. Therefore, integrating philosophical thought into education can serve as an innovative solution for creating a more inclusive, reflective, and contextual learning system.

Abstract

During the 7 rounds of PISA, Indonesian students consistently ranked low in scientific literacy assessments. In the last decade, many studies have been carried out by science education researchers in Indonesia in an effort to improve students' scientific literacy. However, this fact is contradictory to the results of the scientific literacy assessment of Indonesian students which still remains low. This can be caused by not many Indonesian science educators who understand the characteristics of scientific literacy. What are the characteristics of scientific literacy in PISA is important to understand so that teachers can apply learning oriented towards the development of scientific literacy in schools and universities. This article aims to describe the characteristics of scientific literacy referring to the PISA science framework in the period 2000-2021. This article was compiled through a literature review. Scientific literacy is defined as the ability of individuals to devote attention to science-related topics and science ideas as a form of individual reflection. A person who is scientifically literate will always devote attention to logical debates regarding science and technology that require competence: 1) explaining phenomena scientifically; 2) evaluate and design scientific investigations; and 3) interpret data and evidence scientifically. Scientific knowledge consist of content, procedural, and epistemic knowledge. The scientific literacy context consist of health and disease, natural resources, environmental quality, hazards and contamination, and the limitations of science and technology. The PISA science attitude aspect consists of a critical attitude of science in decision making and a creative attitude characterized by the ability to propose scientific ideas. In PISA 2021, scientific literacy assessment is not only present as a core domain, but also integrated with mathematical literacy, reading, and creative thinking.

Abstract

Teacher competencies consist of pedagogical, personality, social, and professional competencies. Science educators must be able to encourage students to become lifelong students who are competent, have character, and behave in accordance with the values of Pancasila, have the competence to become democratic citizens and become superior and productive human beings, and be able to participate in sustainable and resilient global development in facing various challenges. So that to be able to integrate these values into science learning, the conception of these four competencies for science educators must be reformulated by considering the competencies needed for Education for Sustainable Development (ESD), Science Literacy, and strengthening the pupil profile of Pancasila. The results of this study show that pedagogical, personality, social, and professional competencies can be reformulated so that they are relevant to Education for Sustainable Development (ESD), Science Literacy, and strengthening the pupil profile of Pancasila learning. With the presence of this competency, the science teachers will have the ability to facilitate learning for Education for Sustainable Development (ESD), Scientific Literacy, and strengthening the profile of Pancasila learning. simultaneously through the science learning process.

Abstract

This study investigates the effects of varying base materials, specifically coconut shell charcoal (ATK) and corncob charcoal (ABJ), on the characteristics of biobriquettes. The research employs an experimental method, analyzing the impact of different ATK and ABJ proportions on calorific value, ash content, moisture content, density, and combustion rate. The biobriquettes were produced by mixing coconut shell and corncob charcoal with 10% tapioca starch adhesive, molded into cubes, and dried. The results show that increasing the ATK proportion improves the calorific value, with the highest value of 10,640 calories in briquettes with 90% ATK. In contrast, higher ABJ content results in faster combustion rates but lower energy efficiency, with the lowest calorific value of 6,424 calories in briquettes containing 90% ABJ. The study also highlights that all biobriquettes meet Indonesian National Standards (SNI) for moisture content and calorific value, although only the 90% ATK sample meets the ash content standard. These findings suggest that coconut shell charcoal is a superior biomass material for producing high-performance biobriquettes, with a 90% ATK and 10% adhesive combination yielding the best overall results for sustainable energy applications.

Abstract

This research focuses on optimizing the binder percentage in organic waste-based briquettes to improve their calorific value and combustion rate. Conducted through experimental methods, organic waste such as sawdust, dry leaves, and branches were processed into briquettes using varying concentrations of tapioca starch as a binder (10%, 12.5%, 15%, and 17.5%). The experiment evaluated key performance metrics, including calorific value, combustion rate, moisture content, ash content, and briquette density. Results showed that the optimal calorific value (9,234 cal/g) was achieved with 10% binder, while the highest combustion rate (0.586 g/min) occurred at 15% binder concentration. These findings suggest that lower binder percentages result in higher energy efficiency, while higher binder content prolongs combustion. However, increased binder content also led to higher ash production, with the highest ash content recorded at 17.5% binder. The research highlights that balancing the binder ratio is essential for creating briquettes that are both energy-efficient and environmentally sustainable, offering a viable alternative to traditional fuels in Indonesia's pursuit of renewable energy solutions.
