Abstract

This study aims to develop transparent concrete learning media for spatial geometry and evaluate its feasibility, practicality, and effectiveness in supporting students’ understanding of surface area concepts. This development applies the 4D model (Definition, Design, Development, and Dissemination) and involves one media expert, one subject matter expert, and 30 ninth-grade students during the limited dissemination phase. The uniqueness of this study lies in the use of a transparent acrylic model that allows students to clearly observe the relationships among planes, edges, and angles, providing a concrete, visually accessible representation of geometric structures. The research procedure included a student needs analysis, prototype design and production, product validation through expert review, and limited classroom deployment supported by pre- and post-test assessments. Media experts rated the product at 80% (acceptable), while subject matter experts rated it at 87.5% (highly acceptable). Students’ conceptual understanding improved significantly, with the average pre-test score of 81.43 increasing to 100 on the post-test, resulting in an N-Gain of 1.00 (very high). The student response rate reached 66.9% (very practical). These findings indicate that transparent concrete geometric media are feasible, practical, and effective, offering pedagogical advantages for enhancing students’ conceptual understanding through realistic, transparent geometric representations.

Abstract

The formatur election at PC IPM Cepu is an important practice of internal democracy within the Muhammadiyah student organization; however, the manual voting process has frequently led to invalid ballots, lengthy vote recaps, and potential recording errors. This study aims to develop a web-based e-voting system that enforces election rules and improves efficiency and data integrity. In this election, voters are required to select exactly nine candidates, which serves as the core validation constraint of the proposed system. The research employs a Research and Development (R&D) method with a prototyping approach, encompassing needs analysis, system design, implementation using the Flask framework with an SQLite database, and system testing. Automatic selection-count validation is implemented on both the client and server sides, along with a double-vote prevention mechanism to ensure voting integrity. System evaluation involved 30 active PC IPM Cepu participants through functional testing, time-efficiency comparison, and a user-satisfaction survey. The results indicate that the system successfully eliminated invalid ballots, achieving 0% input errors, defined as the absence of votes with an incorrect number of selected candidates across all test cases. In addition, the voting and recapitulation process was accelerated by up to 80% compared with the manual method. User satisfaction was measured using a Likert-scale questionnaire, yielding an overall satisfaction rate of 95% (positive responses), derived from aggregated Likert scores. Despite these promising results, this study is limited by its relatively small sample size and its application within a single student organization. Overall, the findings demonstrate that a simple rule-based e-voting system can serve as an effective digitalization model for internal democratic processes in student organizations, enhancing participation and organizational governance efficiency through technology.

Abstract

Digital transformation in public administration is a strategic effort to achieve governance that is effective, efficient, and accountable. This study examines the implementation of the Rapid Introductory Letter Administration Service System (SIMANTAP) in Samboja District as a digital innovation in personnel services, aiming to identify factors that hinder its optimal operation. A descriptive qualitative approach was employed, with data collected through in-depth interviews, observations, and documentation. Informants included the Head of Samboja District, the Head of the General and Personnel Subdivision, and SIMANTAP operators at district and village levels. Data were analyzed through data reduction, presentation, and conclusion drawing, using Edward III’s policy implementation model, encompassing communication, resources, disposition, and bureaucratic structure. The findings indicate that initial socialization of SIMANTAP reached 85% of target personnel but lacked ongoing communication. While 90% of staff demonstrated readiness and positive commitment, only 60% had stable access to functional computers and reliable internet. No dedicated budget exists in the regional budget (APBD), and structured monitoring mechanisms are absent. The study concludes that SIMANTAP has strong potential as a district-level e-government model, but its adoption is constrained by limited technological infrastructure, inadequate budgetary support, and a lack of systematic evaluation. Strengthening policy guidance, enhancing staff capacity, modernizing ICT infrastructure, and allocating budgets are critical to ensuring sustainable and effective implementation.

Abstract

This study addresses the limited empirical profiling of emotional labor among early childhood teachers in Indonesia by applying the Rasch Rating Scale Model. The research aims to examine teachers’ tendencies in emotional regulation, identify item difficulty levels, and map teacher ability distributions. A total of 312 early childhood teachers participated by completing an emotional labour scale representing four emotional-regulation dimensions. The reported logit range of −0.85 to 0.75 refers specifically to the distribution of item difficulty, which differs from the later reported teacher logit range (−3.5 to +3.2). The analysis revealed high measurement reliability (item reliability = 0.98; person reliability = 0.70) and satisfactory model fit indices. Teachers predominantly demonstrated reflective and authentic emotional regulation, as operationalised by lower difficulty on deep-acting and natural-expression items, indicating these strategies were more readily performed. These findings highlight that emotional labour among Indonesian early childhood teachers is grounded in empathy, warmth, and affective balance, forming an essential foundation for emotionally responsive and humanistic teaching practices.

Abstract

This study aims to synthesize research findings from published articles addressing students’ mathematical communication skills and self-regulated learning. A systematic literature review (SLR) was conducted following a structured, standardized procedure, including the formulation of review questions, database selection, keyword identification, the definition of inclusion and exclusion criteria, article screening, and data extraction. Relevant studies were identified from reputable academic databases and systematically reviewed to ensure methodological rigor and transparency. The results of the analysis indicate that mathematics learning implemented through specific instructional models or learning strategies contributes to improvements in students’ mathematical communication skills and self-regulated learning. Furthermore, several studies report a positive relationship between mathematical communication skills and self-regulated learning in mathematics education. However, other studies reveal no significant relationship between these two variables. Various factors, including differences in sample characteristics, learning contexts, and research designs, influence these inconsistencies. Therefore, further studies using more controlled and consistent methodologies are needed to obtain more specific findings and to identify the key factors influencing the relationship between mathematical communication skills and self-regulated learning, thereby improving the quality of future research.

Abstract

This study aims to develop and psychometrically validate an assessment instrument designed to measure students’ metaphorical thinking ability in mathematics learning, with a specific focus on the Pythagorean Theorem. The instrument was developed using a Research and Development (R&D) framework based on the Oriondo and Antonio model, encompassing test design, empirical tryout, and measurement stages. Six polytomous essay items were constructed according to six indicators of metaphorical thinking: connect, relate, explore, analyze, transform, and experience. Content validity was established through expert judgment using Aiken’s V coefficient, with all items exceeding the minimum validity threshold, indicating strong agreement among experts. Empirical validation was conducted using Item Response Theory (IRT) with the Graded Response Model (GRM), selected for its suitability in analyzing ordered polytomous response data. The results demonstrate that the instrument satisfies the unidimensionality assumption, exhibits strong item discrimination parameters, and shows good model fit across all items. Analysis of the Test Information Function indicates high measurement precision within the ability range of θ −1 to +1, confirming strong local reliability. These findings indicate that the developed instrument is valid, reliable, and capable of providing accurate diagnostic information regarding students’ ability to construct mathematical meaning through metaphors. The study contributes methodologically by demonstrating the applicability of GRM-based IRT analysis for essay-type instruments and substantively by supporting the assessment of higher-order cognitive processes in mathematics learning.

Abstract

Mathematical ability is a core competence that students must master and develop in mathematics education. One instructional model considered effective for enhancing this competence is Problem-Based Learning (PBL), which positions students at the center of learning by engaging them in solving contextual and meaningful problems. Through these activities, students are encouraged to strengthen key mathematical skills, including conceptual understanding, reasoning, and problem-solving. This study aims to comprehensively analyze the impact of the PBL model on students’ mathematical abilities in Indonesia through a meta-analytic approach. A total of 30 studies were systematically reviewed following PRISMA guidelines. Data analysis was conducted using JASP to calculate the pooled effect size, the heterogeneity level, the forest plot, the funnel plot, and the potential publication bias. The meta-analysis produced a summary effect size of 1.132 (95% confidence interval: 0.873–1.390), indicating a large effect. The heterogeneity index (I²=83.26%) showed substantial differences across studies; therefore, a random-effects model was employed. Although the funnel plot showed slight asymmetry, the Fail-Safe N value of 9.29>1 indicated that publication bias did not substantially affect the results. Overall, the findings confirm that PBL has a significant and consistent positive effect on students’ mathematical abilities across various educational levels in Indonesia.

Abstract

This study examines the regulatory framework for assessing environmental damage as a basis for establishing state financial losses in corruption cases and analyzes judicial reasoning in sentencing to realize substantive justice. It addresses a key gap in Indonesian legal practice: the absence of an integrated framework linking environmental damage valuation to state loss calculations, and the limited inclusion of ecological restoration costs in criminal sanctions. The research employs a normative juridical method, drawing on legislative, conceptual, case-based, and comparative approaches, supported by primary, secondary, and tertiary legal materials. Data were obtained through a literature review and limited structured interviews with environmental law experts and practitioners. Within the normative juridical framework, the interviews serve solely as supplementary secondary data to complement and confirm the normative analysis of statutory regulations, particularly to verify the adequacy and practical applicability of the legal framework governing environmental damage assessment and state financial loss calculation. Legal materials were analyzed using qualitative descriptive analysis. The findings indicate that environmental damage calculations rely on ecological components regulated under the Environmental Protection and Management Law, Ministry of Environment Regulation No. 7 of 2014, and Government Regulation No. 22 of 2021. In the sentencing of Harvey Moeis and Nur Alam, judges emphasized abuse of authority, official position, degree of culpability, and motive; however, ecological restoration costs were not systematically integrated into sentencing, thereby constraining the realization of substantive justice. This study recommends adopting a unified guideline linking environmental damage valuation to state financial losses and mandating the incorporation of environmental restoration obligations into criminal sentencing. The research is limited to two court decisions and does not include a broader empirical analysis of sentencing patterns.

Abstract

The rapid development of digital technology has shifted the conventional trading paradigm into e-commerce transactions, which, despite offering efficiency, are highly prone to causing complex disputes between consumers and business actors. To address these potential losses, Law Number 8 of 1999 concerning Consumer Protection mandates the establishment of the Consumer Dispute Settlement Body (BPSK) as an institution tasked with supervision and dispute resolution outside the court to ensure legal certainty. This research employs a juridical-empirical method with statutory and conceptual approaches to analyze the optimization of BPSK's supervisory role and its obligations in handling consumer losses. Research data were collected through in-depth literature studies and exclusive interviews with BPSK officials to comprehensively examine the implementation of the institution's policies, functions, and authorities within the current practice of consumer protection. The results indicate that optimizing BPSK's role as a supervisor faces significant structural obstacles due to the centralization of authority to the provincial level following the enactment of the Local Government Law, as well as the absence of technical guidelines for standard clause supervision, which causes overlapping functions with trade agencies. In the specific context of e-commerce, BPSK's supervision tends to be reactive on the downstream side, acting only after complaints are lodged, while upstream electronic system supervision remains under the control of the Ministry of Trade; a condition exacerbated by the fragmentation of complaint data which has not been integrated across institutions. Regarding the restoration of rights, BPSK has proven effective in adjudicating measurable material damages, such as refunds or product replacements, through conciliation, mediation, or arbitration dispute resolution mechanisms. However, BPSK has significant limitations in handling immaterial losses due to the difficulty of measuring psychological damage parameters and the weak executorial power of its decisions, which often fail if challenged in district court, making the effectiveness of consumer protection currently highly dependent on active consumer participation and voluntary business compliance.
