Abstract

Learning independence is a crucial outcome in modern education, enabling students to take responsibility and initiative in their learning processes. This study examines the relationship between emoji-based self-assessment, teacher role, student perception, and learning independence among elementary school students. Using a quantitative correlational design, data were collected through questionnaires from 160 students familiar with digital learning activities. The instruments measured the four constructs using Likert scales, with reliability confirmed through acceptable Cronbach’s alpha values. The results show that emoji-based self-assessment, teacher role, and student perception are positively and significantly related to learning independence. Emoji-based assessment showed the strongest association, supporting students’ emotional awareness and self-reflection. Teacher guidance and supportive perception of the learning environment further contributed to autonomous learning behaviors. Collectively, these three factors explained 48% of the variance in learning independence. The findings imply that integrating simple, affective digital tools with supportive teaching practices can effectively foster student autonomy. Educators are encouraged to adopt emoji-based reflection methods, strengthen facilitative teacher roles, and cultivate positive classroom climates to promote independent learning, especially in technology-enhanced educational settings.

Abstract

Sektor konstruksi memiliki tingkat kecelakaan kerja yang tinggi karena karakteristik pekerjaan yang kompleks dan berisiko. Job Safety Analysis (JSA) merupakan salah satu instrumen penting dalam penerapan keselamatan dan kesehatan kerja (K3) yang berfungsi untuk mengidentifikasi potensi bahaya, menilai tingkat risiko, serta menetapkan langkah pengendalian sebelum pekerjaan dilaksanakan. Penelitian ini bertujuan untuk mengkaji peran Job Safety Analysis (JSA) dalam penerapan K3 pada proyek konstruksi melalui metode literature review. Sumber data diperoleh dari artikel jurnal nasional dan internasional yang relevan dalam lima hingga sepuluh tahun terakhir. Hasil kajian menunjukkan bahwa penerapan JSA secara konsisten dapat menurunkan tingkat kecelakaan kerja, meningkatkan kesadaran keselamatan pekerja, serta memperkuat pengendalian risiko di lapangan. Namun, implementasi JSA masih sering bersifat administratif dan belum optimal. Oleh karena itu, JSA perlu diterapkan secara operasional dan terintegrasi dalam manajemen proyek konstruksi.

Abstract

The rapid development of digital technology has encouraged the creation of more interactive and accessible learning materials in elementary education, particularly for Integrated Natural and Social Sciences. However, many classroom materials remain conventional and less responsive to students’ learning characteristics. This study aimed to determine the validity of Weebly-based Natural and Social Sciences teaching materials for fourth-grade elementary school students. The research used a descriptive quantitative design with expert validation involving one media expert and one material expert. The instruments consisted of validation sheets covering content accuracy, material depth, contextual relevance, language clarity, conceptual presentation, visual design, navigation, accessibility, and interactivity. The data were analyzed using descriptive statistics and Aiken’s V to measure expert agreement. The results showed that the media expert validation obtained a total score of 138 with an average of 4.60, while the material expert validation obtained a total score of 134 with an average of 4.47. The Aiken’s V values were 0.90 for media and 0.87 for material, both indicating very high validity. These findings show that the developed Weebly-based teaching materials are highly feasible and appropriate for use as digital learning resources in elementary school. The study implies that Weebly can support the development of structured, interactive, and pedagogically relevant teaching materials that align with student needs and curriculum demands.

Abstract

Membrane osmometry is a crucial analytical technique for determining the molecular weight of macromolecules, demanding highly selective semi-permeable membranes to prevent solute leakage. This study investigates the effect of solvent evaporation time (1 to 5 minutes) during the phase inversion fabrication of cellulose acetate (CA) membranes on their physicochemical properties and semi-permeability. The synthesized membranes were evaluated for macroscopic appearance, density, swelling degree, and semi-permeability performance using dextran (100-200 kDa) as a model macromolecule. The results demonstrated that while the macroscopic structures remained uniform, prolonging the evaporation time significantly altered the microscopic morphology. Increasing the evaporation time to 5 minutes maximized the localized polymer concentration, resulting in the highest membrane density (1.55 g/mL) and the lowest swelling degree (17.62%). This highly compact structure provided a superior physical barrier, yielding the most optimal semi-permeability with minimal solute leakage. Furthermore, the application of this 5-minute optimized membrane in a membrane osmometer successfully determined the average molecular weight of dextran to be 122.45 kDa, which perfectly aligns with the theoretical range. The analytical measurement exhibited excellent reproducibility with a coefficient of variation (CV) of 1.8% and an accuracy of approximately 80%. These findings conclusively establish that controlling the evaporation time is a highly effective approach to tailoring the strict selectivity of CA membranes for precise osmometric applications.

Abstract

The gas sensor performance can be improved by optimizing the testing chamber design, including volume, shape, gas inlet/outlet positions, and sensor array. We studied the effect of chamber design on the gas sensor's response patterns characteristics in differentiating Robusta coffee aroma from Sidomulyo, and Bangsalsari, Jember. Hemisphere and cylindrical chambers, with three variations for each model, and a ring chamber, were used as model chambers. Eight types of gas sensors (MQ-135, MQ-136, MQ-2, MQ-3, MQ-6, MQ-7, MQ-8, and MQ-9) were used in the sensor array system to examine the gas sensor instrument performance. The resulting responses were analyzed using the reproducibility, response time, and principal component analysis (PCA) test. The result shows that the reproducibility value for all hemisphere chamber models, cylindrical chamber model-1, and ring chamber indicated an excellent sensor performance (%RSD<20%). Meanwhile, the cylindrical chambers model-2 and 3 resulted in %RSD>20%, indicating the low performance of the gas sensor. Among all variations, hemisphere chamber model-1, a hemisphere chamber with the inlet position lower than the outlet gas position, has the best performance due to the shortest response time, high-intensity signal, and performing ability to distinguish the response patterns characteristics of Robusta coffee aroma from Sidomulyo and Bangsalsari, Jember, Indonesia. In this study, we found that changing the testing chamber design, volume, and inlet/outlet position resulting different gas sensor responses to the coffee aroma. The proposed instrument can distinguish the coffee aroma from a different origin.

Abstract

The intricate aroma of coffee arises from a complex blend of volatile compounds, each characterized by distinct attributes and intensities. This study focuses on synthesizing and characterizing the PANI/GO composite. It explores the impact of sensor thickness, rooted in the PaNi/GO composite, on its responsiveness to coffee aroma. Moreover, the findings hold promise as a reference point for sensor development. The PANI/GO composite, doped with HCl, was synthesized using a chemical oxidative polymerization technique in an aqueous solution, employing ammonium persulfate (APS) as the oxidant. Functional group analysis was conducted on the synthesized PANI/GO composite via FTIR (Fourier Transform Infrared). Subsequently, the composite was employed to create a gas sensor with varying thicknesses—0.14, 0.21, 0.28, 0.35, and 0.44 mm. This PANI/GO gas sensor was evaluated using robusta coffee steam from the Sidomulyo region, with resistance measurements performed using a multimeter. The optimization process encompassed sensor conductivity, sensitivity, response time, and repeatability considerations. The most effective sensor thickness emerged as 'Sensor 4,' possessing a 0.35 mm thickness, showcasing a conductivity of 4.69 x 10-9 S/cm, sensitivity of 0.67, response time of 18 seconds, and repeatability of 2.10%. These outcomes hold significant implications for enhancing sensor design and performance, particularly in capturing intricate aromatic profiles such as coffee scents.
