Abstract

Observations carried out at SMAN 2 Rejang Lebong show that readiness to implement the independent curriculum and the use of the Platform Merdeka Mengajar (PMM) in its implementation is still lacking. So, it is necessary to assist in the use of PMM in implementing the independent curriculum at SMAN 2 Rejang Lebong. The aim of this service is to introduce the features in PMM for Mathematics and Science (MIPA) teachers at SMAN 2 Rejang Lebong. Providing knowledge and skills for MIPA teachers at SMAN 2 Rejang Lebong regarding the use of PMM in implementing the independent curriculum. The target of this activity is MIPA teachers at SMAN 2 Rejang Lebong. The total number of targets is around 22 people. Furthermore, participants who had received training directed teachers in other fields of study who had not been invited to this activity. The methods used in this activity are training and workshops, guided assignment work and evaluation monitoring at the final stage. Based on the results of the service that has been carried out, teachers are very enthusiastic about participating in the training. As many as 100% of teachers have successfully opened an account at PMM and 85% have utilized the features available at PMM.

Abstract

This study aims to develop interactive learning media on the topic of complex reaction kinetics as an effort to stimulate students' systematic thinking skills. This type of research is development research using the ADDIE model. The test subjects in this study were students of the Chemistry Education Study Program who participated in the Chemistry Kinetics course in the 2022/2023 academic year. The data collection techniques in this study included feasibility data from the developed media based on expert validation of the media and material, as well as responses from students participating in the course regarding the developed media. The instruments used in this study were a questionnaire on the needs of course participants, a validation sheet, and a student response questionnaire. The results showed that the interactive learning media developed was deemed very feasible from the perspective of media and material validation, with average percentages for media and material validation of 92.5% and 93.75%, respectively. The results of the response test of students taking the Chemical Kinetics course to the interactive media developed showed an average score percentage of 86.6% and was in the very good category. The responses of the students also showed that the media developed could stimulate students' systematic thinking skills in the topic of complex reaction kinetics.

Abstract

Climate change is a global issue primarily driven by increased carbon dioxide levels in the atmosphere. Numerous studies have been conducted to reduce carbon dioxide emissions as a strategy to mitigate its effects. Soils, particularly volcanic soils, are known to store significant amounts of carbon - second only to deep-sea reservoirs. This study aims to investigate the soil organic carbon content distribution of volcanic soils along elevation gradient on Kaba Volcano in Bengkulu Province, Indonesia. Nine soil samples, both disturbed and undisturbed, were collected at a depth of 10 cm from three locations at different elevations: the foothill (1360–1380 m a.s.l.), hillside (1610–1620 m a.s.l.), and hilltop (1930–1940 m a.s.l.). Undisturbed samples were collected using a 70-mm core cylinder to determine soil bulk density, while disturbed samples were taken with a shovel and analyzed for soil organic carbon, pH, and particle size distribution (sand, silt, and clay). The results showed that the hillside samples had the highest soil organic carbon content, while the hilltop samples had the lowest. Correspondingly, the lowest soil pH was observed at the hillside, and the highest bulk density was found at the hilltop. Particle size analysis revealed that sand and clay content at the hillside were similar to those at the foothill and both were higher than those at the hilltop. The lower soil organic carbon at the hilltop may be attributed to drier conditions and reduced vegetation cover compared to the foothill and hillside.

Abstract

Oil palm kernel shells (KS) are a byproduct of oil palm processing that often receives little attention and is treated as waste. Biochar has various applications for example as an adsorbent. This study aims to prepare and characterize biochar from KS and evaluate its effectiveness in adsorbing Cu2+. The biochar (BKS) was prepared by heating KS in a furnace at 500°C for three hours. The resulting material was sieved using a 50-mesh sieve to ensure uniformity. Characterization of BKS showed that it had a surface area of 319.9 m2 g-1, a total pore volume of 0.168 cm3 g-1, and an average pore size of 1.049 nm, classifying it as microporous. Analysis for its functional groups revealed the presence of functional groups with stretching vibrations corresponding to O-H (3400 cm-1), C-H (2920 cm-1), C=O (1700 cm-1), C=C (1432-1690 cm-1), and C-O (1000-1200 cm-1). SEM imaging displayed a clear porous structure with well-defined channels. Adsorption isotherm experiments demonstrated that Cu2+ adsorption data using BKS aligned better with the Freundlich isotherm model than with the Langmuir model. These findings indicate that BKS derived from KS is less effective for removing Cu2+ ions from water compared to other biochars.
