Abstract

Six wood species from West Java which are ki hiur (Castanopsis acuminatissima A.DC.), tunggeureuk (Castanopsis tunggurut), huru pedes (Cinnamomum iners Reinw.Ex Bl.), huru koja (Litsea angulata Bl.), ki kanteh (Ficus nervosa Heyne) and kelapa ciung (Horsfieldia glabra Warb) have been distillated by dry distillation at temperature 450°C-500°C for five hours in the retort distillation. Distillates from the dry distillation in form of charcoal, tar and liquid are calculated. The results exhibited charcoal quality of six woods meet the standards of Indonesia for charcoal and charcoal briquettes with calorific values ranging from 6743-6795 cal/g, fixed carbon ranging from 79.42 % - 82.37 %. Charcoal yield ranging from 27.43 % -33.55 % . Pearson correlation analysis on the lignin content and woodgravity to charcoal calorific value indicates that the lignin content has a significant correlation to the calorific value of charcoal.

Abstract

This article examines the dilemma surrounding the use of “empty columns” in Indonesia’s local elections (Pilkada). Empty columns were introduced during the 2017 simultaneous regional elections in response to the rising number of uncontested races, where only a single candidate pair appeared on the ballot. Such races have increased in each electoral cycle, with 25 single-candidate contests occurring in 2020. Although empty columns were designed to preserve democratic contestation by ensuring voters have at least two options, the regulatory and political framework governing them remains fragile. This study aims to explain why empty columns have become a dilemma within contemporary electoral political discourse. This research employs a qualitative methodology with an exploratory analytical approach, drawing on empirical patterns identified through an extensive review of relevant literature. The findings indicate that the empty column represents a fundamentally contradictory mechanism: while it is formally intended to sustain competition, it lacks the political infrastructure necessary for effective contestation and thus functions as a nominal rather than substantive electoral alternative. As a result, empty columns are structurally disadvantaged and struggle to counterbalance the dominance of single-candidate pairs, ultimately undermining their intended role in strengthening democratic practice.

Abstract

Deep learning and human-AI collaboration models have become a policy direction in Indonesianprimary education following the adoption of meaningful learning approaches within the KurikulumMerdeka in 2025-2026, in line with the global trend of integrating artificial intelligence (AI) intoprimary curricula. However, systematic studies examining the characteristics, effectiveness, andimplementation challenges of these two integrated approaches at the elementary school level remainlimited. This study aims to analyze and synthesize prior research findings regarding the design,implementation, and impact of deep learning models supported by human-AI collaboration inelementary classrooms, and to map research gaps relevant to the Indonesian context. This study employed a systematic literature review method following the PRISMA protocol, searching Scopus,ERIC, Google Scholar, Garuda, and SINTA databases using the keywords deep learning elementaryeducation, human-AI collaboration classroom, and AI literacy primary school, covering publicationsfrom 2020 to 2026. A total of 19 articles meeting the inclusion criteria were thematically analyzed andcoded into four theme categories. The coding results show that the characteristics of deep learning modelsdominated the findings (36.8%), followed by forms of teacher-AI collaboration (31.6%), impact onlearning outcomes and motivation (21.1%), and challenges and supporting factors for implementation(10.5%). Project-based learning and group collaboration supported by adaptive AI tools are mostconsistently associated with improved conceptual understanding, motivation, and digital literacyamong elementary students, although success depends heavily on teacher readiness, infrastructureavailability, and alignment with children's cognitive development stages. Key challenges includelimited teacher training, digital infrastructure gaps, and the absence of clear ethical guidelines for AIuse among elementary-aged students. This study recommends the development of co-design-basedteacher training models and contextual ethical frameworks as a foundation for AI integration policy inIndonesia's elementary curriculum

Abstract

Critical reading ability is an essential skill that should be developed in elementary school, particularly in understanding fable texts that are rich in conflict, cause-and-effect relationships, and moral messages. Reading instruction, however, has generally remained focused on literal comprehension, so students' ability to interpret, analyze, and evaluate texts has not developed optimally. This study aims to determine the effect of the SQ3R model (Survey, Question, Read, Recite, Review) on the critical reading ability of fifth-grade students on fable texts. The study used a quasi-experimental method with a non-equivalent control group design, involving 44 fifth-grade students of SDN Cigasong 1 divided into an experimental class (SQ3R model) and a control class (Direct Instruction model), each consisting of 22 students. Data were collected through multiple-choice and essay tests and analyzed using the Paired Sample t-Test and Independent Sample t-Test with IBM SPSS Statistics version 30. The results show that the experimental class's pretest mean score of 54.27 increased to 86.86 on the posttest, while the control class only increased from 48.68 to 51.59. The Paired Sample t-Test produced a significance value of 0.000 (< 0.05), indicating a significant effect of the SQ3R model on critical reading ability. The Independent Sample t-Test also showed a significance value of 0.000 (< 0.05), confirming a significant difference between the experimental and control classes. Thus, the SQ3R model proved more effective than the Direct Instruction model in improving fifth-grade students' critical reading ability on fable texts.

Abstract

Mathematical problem-solving ability is an essential competency that should be developed from the elementary school level. One learning model with the potential to foster this ability is the Read, Answer, Discuss, Explain, and Create (RADEC) model. This study aims to analyze the characteristics of previous research and examine the contribution of the RADEC model to elementary school students' mathematical problem-solving ability. The study employed a Systematic Literature Review (SLR) following the PRISMA 2020 guidelines. Literature was retrieved from the Google Scholar and Scopus databases, and the articles were screened based on predetermined inclusion and exclusion criteria, resulting in 15 eligible studies for analysis. The findings indicate that the reviewed studies were predominantly quasi-experimental, complemented by Classroom Action Research and Research and Development approaches, and were implemented across various elementary mathematics topics. Furthermore, the RADEC model positively contributes to students' mathematical problem-solving ability by enhancing conceptual understanding, mathematical thinking, mathematical communication, learning achievement, and learning interest. Therefore, the RADEC model can be considered an effective instructional alternative for improving elementary school students' mathematical problem-solving ability.

Abstract

This study was motivated by the low science process skill outcomes among fourth-grade students at SDN Panyingkiran 1. The study aimed to determine the effect of the experiential learning model on science process skills, considering the critical thinking levels of fourth-grade students at SDN Panyingkiran 1, Majalengka Regency, during the 2025/2026 academic year. A quasi-experimental method with a 2 × 2 factorial design was employed. The sample consisted of 48 students divided into two groups: an experimental class using the experiential learning model and a control class using the direct instruction model. Non-probability sampling specifically purposive sampling was used to select the participants. Data were collected using science process skills tests and critical thinking tests, and were analyzed using an independent sample t-test and two-way anova. The results revealed that (1) there was a significant difference in science process skills between the experimental and control classes; (2) there was a significant difference in science process skills between students with high and low critical thinking levels; and (3) there was no significant interaction between the learning model and critical thinking levels regarding students' science process skills. The findings indicate that the experiential learning model influences students' science process skills, regardless of whether they possess high or low levels of critical thinking.
