Abstract

ABSTRACT Learning barriers often faced by students in lower grades of Elementary School are difficulties in beginning reading. This problem was also found in class IIA students of Kembaran State Elementary School, which was the main focus of this study. The purpose of this study was to provide a deeper understanding of the types of beginning reading difficulties experienced by students. This study used a qualitative approach with a case study method. The subjects of the study consisted of 13 students who had difficulty reading, class IIA teachers, and 13 parents of the students. Data collection techniques were carried out through observation, interviews, and document analysis. Data validity testing was carried out using the Miles Huberman model, which includes data collection, data reduction, data presentation, and drawing conclusions. The results of the study showed that 13 students of class IIA of SD Negeri Kembaran had difficulty in beginning reading, which included: a) Difficulty in recognizing the alphabet, where 2 students did not recognize letters from A to Z, b) Difficulty in recognizing consonants, with 3 students only knowing a few consonants, c) Difficulty in reading diphthongs, where 4 students had difficulty pronouncing diphthongs or stuttered when reading them, d) Difficulty in reading words, where 4 students still spelled words when reading, e) Difficulty in reading sentences, where 13 students were not yet fluent in reading sentences.

Abstract

Machine Learning (ML) offers an innovative approach to reservoir characterization, yet its widespread application is hindered by poor cross-basin generalization. Specifically, most models validated on intra-basin data fail to account for the geological heterogeneity encountered in new settings. This study addresses this limitation by quantifying the geological domain shift that hinders direct model transferability and by proposing a conceptual framework to overcome it. This approach is designed to systematically address geological variability by identifying local electrofacies structures before attempting predictive modelling. To validate the necessity of this framework, we conducted a preliminary empirical study comparing the Talang Akar Formation in the North West Java Basin and the Menggala Formation in the Central Sumatera Basin (Basins A and B). This study empirically demonstrates that, despite shared fluvial-deltaic depositional environments, the intrinsic statistical structures of the two basins diverge significantly. A quantitative analysis revealed a severe domain shift, evidenced by a large Euclidean distance between cluster centroids and a low adjusted Rand index (ARI) of 0.113 when applying direct analog mapping. These findings empirically demonstrate that direct model transfer is ineffective because of second-order geological controls. Consequently, this study establishes the critical need for the proposed UL-SL strategy to adaptively handle domain shifts, providing a geologically grounded roadmap for accurate characterization in frontier and data-scarce basins.

Abstract

CO2 storage screening ensuring the long-term containment of injected CO2 and the integrity of carbon capture and storage. In Indonesia, robust seal evaluation is constrained by the limited availability of caprock core data. This study develops a dimensionless Caprock Quality Index (CQI) as a practical CO2 storage screening tool based on displacement pressure (Pd) and caprock thickness (h). Displacement pressure is estimated using an empirical Pd equation derived from existing caprock core data. The CQI provides a quantitative classification of seal quality within the 0-1 range, where values closer to 1 indicate better caprock quality. Based on the data availability of this study, the results show that the Banggai and Salawati basins currently exhibit the highest CQI, indicating strong suitability for CO₂ storage. This study provides a framework for conducting preliminary CO₂ storage screening, particularly valuable in settings where caprock core data are sparse and contributes to the development of a more efficient, data-driven framework for future CCS planning and implementation.

Abstract

This study aimed to compare the effects of triangle passing and quadrangle passing drills on the passing quality of U-17 Taruna Gomong FC football players. The study employed a quantitative approach with a quasi-experimental two-group pretest-posttest design. The population consisted of 24 players, and 16 players who met the inclusion criteria were selected through purposive sampling. The sample was then divided into two equal groups using ordinal pairing based on pretest scores. Group A received triangle passing training, whereas Group B received quadrangle passing training for 18 sessions over six weeks. The instrument used was a 30-second passing and ball-control test adapted from Nurhasan. Data were analyzed using the Shapiro-Wilk normality test, homogeneity test, paired-sample t-test, and independent-sample t-test at a significance level of 0.05. The results showed that triangle passing training significantly improved passing quality (t = 10.58; p = 0.000) with a 15.38% increase. Quadrangle passing training also significantly improved passing quality (t = 5.36; p = 0.001) with a 12.75% increase. However, the difference between the two training methods was not statistically significant (t = 2.030; p = 0.062). These findings indicate that both drills can be used to improve players’ passing quality, although neither method was statistically superior.

Abstract

Limbah cair kelapa sawit (POME) merupakan hasil dari proses perebusan/sterilisasi dan klarifikasi yang mengandung sludge, air kondensat, dan air sisa cucian pabrik. Pengolahan konvensional POME menggunakan sistem kolam terbuka kurang efektif karena dapat menimbulkan masalah lingkungan. Oleh karena itu, diperlukan alternatif pengolahan POME yang ramah lingkungan seperti penggunaan biokoagulan ampas tebu. Penelitian ini bertujuan untuk mengetahui efektifitas dan pengaruh dosis biokoagulan dari ampas tebu pada pengolahan POME. Ampas tebu dengan kandungan lignoselulosa tinggi, memiliki potensi sebagai agen biokoagulan. Ampas tebu yang telah dipreparasi kemudian didelignifikasi dengan NaOH 8% pada suhu 120°C selama 120 menit untuk menghasilkan biokoagulan. Pengaplikasian dilakukan dengan proses klarifikasi dengan variasi dosis 7,5; 10; 12,5; 15; dan 17,5 (g/L). Pengaplikasian bikoagulan dilakukan pengadukan cepat selama 2 menit, pengadukan lambat selama 20 menit, dan diikuti dengan sedimentasi selama 60 menit. Setelah itu dilakukan analisis pH, TSS, dan kekeruhan. Peningkatan dosisi bikoagulan meningkatkan nilai pH dan penurunan nilai kekeruhan. Dosis optimal diperoleh pada 10 g/L dengan efektivitas penurunan TSS sebesar 32,49%, kekeruhan sebesar 9,43%, dan nilai pH 5,1.

Abstract

Objective: This study aims to analyze the level of preparedness among Indonesian diaspora students in the face of potential disasters, particularly earthquakes and tsunamis, and to identify aspects of preparedness that still need to be improved. Method: This study employed a quantitative approach using a survey method involving 30 fifth-grade students at Sekolah Indonesia Kuala Lumpur (SIKL), Malaysia. The instrument used was the LIPI-UNESCO/ISDR Disaster Preparedness Questionnaire Series 3, which covers four main parameters: knowledge and attitudes, emergency response plans, early warning systems, and resource mobilization. The data was analyzed by calculating the readiness index for each parameter and the overall student readiness index. Results: The research findings indicate that the disaster preparedness level of diaspora students falls into the "nearly ready" category, with an index score of 58.5. The knowledge and attitude (60.8) and emergency response plan (59.6) parameters showed relatively better results, indicating that the students already possess a basic understanding of disaster risks and initial response measures. However, the parameters for early warning systems (44.1) and resource mobilization (40) remain in the low category, indicating limitations in practical experience, understanding of early warning systems, and the ability to act quickly and in a coordinated manner when a disaster occurs. Novelty: This study offers a novel perspective by examining the disaster preparedness of Indonesian diaspora students in the context of cross-border education, where disaster risk characteristics vary. The study highlights how geographical displacement, limited experience with disasters, and differences in disaster communication systems influence students’ level of preparedness. In addition, this study integrates four dimensions of preparedness (knowledge and attitudes, emergency response planning, early warning systems, and resource mobilization) to provide a more comprehensive picture of the preparedness of diaspora students to cope with disasters.
