Abstract

This study aimed to analyze the relationship between physical activity and students’ mental health in the digital era at SMAN 2 Labuapi. The study employed a quantitative approach with a correlational design. The population consisted of 552 students, and 59 students were selected as the sample using purposive sampling. Physical activity was measured using the Physical Activity Questionnaire for Adolescents (PAQ-A), while mental health was assessed using the Self Reporting Questionnaire-20 (SRQ-20). Data were analyzed descriptively and bivariately using the Chi-Square test. The findings showed that most students were in the moderate physical activity category (62.7%), while 55.9% were classified as having good mental health or no indication of emotional mental disorders. The Chi-Square test revealed a significant relationship between physical activity and mental health (χ² = 7.589; p = 0.022). Students with higher levels of physical activity tended to have better mental health conditions. These findings indicate that physical activity is an important protective factor for students’ psychological well-being in the digital era.

Abstract

This article explores the implementation of religious moderation education through extracurricular activities in vocational high schools. This research uses a qualitative approach that is analytically descriptive. The research location is at SMK 17 August Bangsri Jepara. Data collection in this study used interview techniques, observation, documentation studies, literature studies, and field notes. The data analysis is like Miles and Huberman, namely: data reduction, data presentation, and conclusion drawing. In this study obtained the results that religious moderation education at SMK 17 August Bangsri Jepara can be carried out through several strategies, among others: First, extracurricular activities of scouts. To produce moderate scout members, of course, they must be accompanied by moderate mentors to teach the value of religious moderation; Second, camp activities: Ambalam Guest Reception Camp. In this activity, scouts are taught to respect various religious beliefs, teach moral values, and develop positive religious attitudes. One of the activities taught is the appreciation of the Dasa Darma Scout is very important and can be applied to extracurricular scouting activities to shape the character of participants for the better, in this case the attitude of religious moderation; Third, camp activities: Bantara Camp. In this case, participants are taught some education, including: character building, life skills, and social care. One of them is the Scout Oath, this activity has a positive impact in encouraging moderate attitudes for participants and also for participants at school. Manifestations of moderate education for participants include: universal values; openness; tolerance; and cooperation.

Abstract

Accurate characterization of viscosity behavior is essential for the design of advanced heat-transfer fluids, particularly hybrid emulsions involving immiscible polar and non-polar phases. However, the rheological behavior and molecular interactions of silicone oil/ethylene glycol (EG)–water emulsions stabilized with surfactants remain insufficiently understood. Therefore, this study experimentally investigates the temperature-dependent viscosity and molecular characteristics of low-viscosity Silicone Oil PMX-200 dispersed in an EG–water (10:90 v/v) base fluid stabilized with Tween 80 over a temperature range of 30–70 °C. Fourier Transform Infrared (FTIR) spectroscopy was employed to evaluate molecular interactions and emulsion stability, while viscosity measurements were performed using a calibrated rotational rheometer under controlled thermal conditions. FTIR analysis confirmed characteristic polydimethylsiloxane (PDMS) absorption bands associated with C–H, Si–CH₃, and Si–O–Si vibrations. The attenuation of Si–O–Si intensity and the appearance of broad O–H stretching bands indicated enhanced interfacial interactions between the hydrophobic silicone-oil phase and the polar EG–water medium, confirming successful emulsification by Tween 80. Rheological measurements showed that viscosity decreased significantly with increasing temperature, from 6.2 mPa·s at 30 °C to 4.2 mPa·s at 70 °C. The emulsions exhibited nearly Newtonian behavior with flow behavior indices close to unity (n ≈ 1), indicating minimal shear-rate dependence within the investigated range. The viscosity–temperature relationship followed Arrhenius-type behavior, with activation energies decreasing from 8.93 kJ·mol⁻¹ for SO‒50 to 4.86 kJ·mol⁻¹ for SO‒10, indicating enhanced molecular mobility at lower silicone-oil concentrations. Experimental deviations remained below 2% compared with literature data, confirming measurement reliability. The novelty of this work lies in integrating FTIR molecular characterization, rheological validation, and Arrhenius-based viscosity modeling for silicone oil/EG–water emulsions. The proposed correlation provides reliable viscosity prediction for thermal-fluid design and CFD-based heat-transfer simulations.

Abstract

Electrical discharge machining (EDM) is one method of manufacturing precise parts with materials that are difficult to cut. EDM has wide applications in the automotive and aerospace industries. The process of electrical erosion consists of the removal of material from the workpiece due to an electric discharge that occurs between the work electrode and the workpiece surface. The electrodes and the workpiece are connected to an electric charge generator.This thesis presents the results of experimental research on electrical discharge machining (EDM), in which the workpiece material is SPHC plate and copper electrodes. The method used in this experiment is the Taguchi method to determine the optimal parameters by varying the current parameters (7A, 12A and 15A), spark on time (210 s, 340 s and 400 s), Gap (50V, 45V and 40V). Process performance measured in this case is the Material Removal Rate and Surface Rougness. The results of the experiment using the Taguchi method showed that the largest optimal MRR was 82.10 mm3/min at current=15 A; Spark on time= 340 s; gap= 50 volts. For the smallest optimal value of SR is 26.00 m at 7 A current; Spark on time= 210 s; gap= 45 volts.

Abstract

Electrical discharge machining (EDM) is a non-conventional machining process by feeding the workpiece material by means of an electric spark (spark) through the gap between the electrode and the workpiece containing a dielectric fluid. The EDM process is influenced by the material being processed, electrode material, discharge current, spark on time, spark gap, dielectric fluid and so on. The combination of these parameters will produce different machining characteristics. The purpose of this study was to determine the value of the material removal rate and surface roughness of the workpiece (Surface Roughnes), using graphite electrodes and using the Taguchi method to determine the optimal parameters by varying the current parameters 10A, 13A. , 16A, spark on time 210µ, 340µ, 400µ and gap 40, 45, 50.

Abstract

The G. A. Siwabessy Multi-Purpose Reactor (RSG–GAS) is included in the MTR type research reactor having a straight plate-shaped fuel element fueled by uranium silicide with a density of 2.96 gU/cm3. This research aims to analyze the influence of the geometry of the straight plate model fuel element on the criticality and distribution of neutron flux in the RSG–GAS reactor core. Monte Carlo simulations with OpenMC were carried out on five types of fuel elements namely from RSG–GAS, HANARO, WWR-SM, MARIA, and BRR, with mass U235 250 grams per fuel element. The research results show that the geometric shapes of different fuel elements influence the criticality value and flux distribution in the same core. The highest criticality value was obtained for the fuel element from HANARO followed by RSG-GAS and the lowest was obtained for the fuel element from WWR-SM. The flux distribution in the fuel elements from MARIA and BRR has a better flux distribution.
