Abstract

Ammonia synthesis in conventional industrial plants typically employs fused iron-based catalysts under harsh conditions (temperatures of 400–700 °C and pressures exceeding 300 atm), resulting in significant energy consumption. This study investigates the potential of using a Mn0.8Zn0.2Fe2O4 catalyst, synthesized under varying sintering temperatures and magnetic field inductions, to enable ammonia synthesis under milder conditions. Additionally, process optimization was carried out using Response Surface Methodology (RSM) and Central Composite Design (CCD). Catalyst characterization results indicate that the crystallite size of Mn0.8Zn0.2Fe2O4 increases with higher sintering temperatures. The catalyst exhibits a near-spherical morphology with notable agglomeration. Magnetic property analysis shows that samples sintered at 700 °C and 900 °C display ferrimagnetic behavior, while the sample sintered at 1100 °C exhibits ferromagnetic characteristics. Temperature-Programmed Reduction (TPR) revealed a maximum reduction peak at 788 °C for the catalyst sintered at 1100 °C, indicating enhanced reducibility. Ammonia formation was successfully achieved using a Helmholtz coil-assisted synthesis method, where the produced ammonia was captured in acidic and basic media in the form of NH₄OH and (NH₄)₂SO₄, confirming the catalytic activity of Mn0.8Zn0.2Fe2O4. The RSM model demonstrated high accuracy with an R² value of 99.73%, and residual analysis confirmed normal distribution, validating model assumptions. The optimal synthesis parameters determined were a sintering temperature of 700 °C, magnetic induction of 0.14 T, and a reaction temperature of 28 °C. The minimal deviation between predicted and experimental responses confirms the reliability and predictive accuracy of the quadratic regression model.

Abstract

This study aims to examine a test instrument to ensure its conformity with appropriate formats and procedures for measuring senior high school students’ mastery of temperature and heat concepts. The instrument consists of 14 multiple-choice questions. This study uses a quantitative descriptive method to evaluate and produce a high-quality and valid test instrument. The instrument underwent revision through consultation with expert lecturers and was then empirically tested on 95 students at SMAN 1 Pamekasan as respondents. The test items were analyzed using SPSS version 30, covering four stages of empirical analysis: validity testing, reliability testing, item difficulty analysis, and item discrimination analysis, all conducted using classical test theory parameters. Based on the results of the point biserial analysis, questions 1, 9, and 11 are below standard. Reliability shows a Cronbach's alpha of 0.708, which means it is reliable. The difficulty level test results show that out of 14 questions, 3 questions are categorized as difficult and 1 question is very easy. In the discrimination test, 5 questions are categorized as poor, 3 questions are moderate, and 7 questions are good. Overall, 11 questions were deemed acceptable and passed the empirical test, while 3 questions (numbers 1, 9, and 11) were disqualified. The weakness of this instrument testing is that the results are highly dependent on the abilities of the participants. For example, question number 9, which was adapted from PhysPort and simplified in language, still had to be disqualified because it did not meet the empirical criteria.

Abstract

This study develops a low-head smart picohydro system for rural electrification optimized using the Queen Honey Bee Migration (QHBM) algorithm. The system includes a propeller turbine, axial generator, charge controller, inverter, and battery. QHBM optimizes flow rate, head, system efficiency, output power, and energy cost to achieve the best technical and economic performance. For comparison, Particle Swarm Optimization (PSO) is used, known for its fast convergence but prone to local optima. Results show that at a 0.65 m head, QHBM produces 546.68 W, higher than PSO (546.48 W) and manual calculation (530 W), with 50% faster convergence. The proposed system supports sustainable and affordable energy access for off-grid communities and offers potential for renewable energy startup innovation.

Abstract

Students often struggle to identify and position themselves in physics class which is known as the conceptualization of physics identity. One of the contributing factors is the limited learning environment that fosters engagement and a sense of belonging in physics. This study aims to develop, validate, and test the practicality of physics learning tools in a non-formal context, specifically through a physics club. The research employs the Research and Development (R&D) design with the 4D model (Define, Design, Develop, and Disseminate). The instruments were validity and practicality questionnaires. The content validity was assessed by two experts: one physics lecturer and one physics teacher. In addition, the practicality testing involved one physics teacher and 36 students from Laboratory Senior High School UM (Universitas Negeri Malang). Data were analyzed through descriptive statistic by presenting the percentage of the validity and the aspect of practicality. The developed products include a physics club program book, a physics club activity module, and a physics club material book. The validity results showed that the program content achieved 94% (highly valid), the media and material validity of the physics club activity module scored 81% and 89% respectively (highly valid), and the media and material validity of the physics club material book scored 89% and 91% (highly valid). Practicality tests by teachers and students yielded scores of 97% (highly practical) and 77% (practical), respectively. Based on these results, the physics club learning tools are declared valid and practical for use in order to strengthen students’ physics identity.

Abstract

The counter electrode (CE) in dye-sensitized solar cells (DSSCs) has an essential impact on the photovoltaic performance and long-term stability of DSSCs. Carbon materials, such as activated carbon (AC) and graphene, are attractive candidates for CE materials in DSSCs due to their low cost, high thermal conductivity, and high specific surface area. In this work, the manufacture of carbon CE using the knife coating method. Then, its performance was tested using a solar simulator and electrochemical impedance spectroscopy (EIS) testing. The samples with carbon and graphene counter electrodes show efficiencies of 0.29% and 0.23%, respectively. The findings revealed that the CE-based carbon materials had a significant impact on the performance of DSSCs. The proposed carbon materials, having low-cost fabrication, high conductivity, high thermal stability, and good corrosion resistance to electrolytes, may offer a promising solution for solar cell applications.

Abstract

The solar-powered Nila floss production system was developed to address the issues encountered by the Darul Hikmah Al Hasani Foundation in Merjosari, Malang. Although the partner owns nila fish ponds with high potential, they have not been optimally utilized as an income source. This technology enhances production effectiveness and efficiency while reducing operational costs by utilizing solar energy. The system integrates several machines: a bone–meat separator, an autoclave, a meat shredder, a mixt-roaster, and an oil spinner, all powered by solar panels. This application of scientific knowledge provides tangible benefits for the partner, including cost savings, more efficient production, and enhanced income generation through the development of value-added fish products. The program will run for ten months, starting with preparation and installation, followed by operational training and mentoring. A marketing analysis will also be conducted to strengthen product competitiveness and expand market reach for Nila Fish Floss.
