Abstract

The development of technology in the world of education is a demand for the curriculum, so currently technology is developing, namely Augmented Reality, which allows its use to interact in a real way with the system. The application of Augmented Reality can be a solution to educational problems that require the application of science and technology in every subject, especially chemistry in chemical equilibrium material. Augmented Reality-based LKPD was developed based on validation results, teacher and student responses. The development method used is the research and development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The data collection techniques used were teacher interviews, analysis of student needs, media and material validation sheets and student response questionnaires. Based on validation carried out on interactive LKPD based on Augmented Reality on chemical equilibrium material, the level of validation by media expert validators was 95% with the criteria "very feasible". And a response test was carried out on students, obtaining a percentage of 76% with the "interesting" criteria. So it can be concluded that overall the interactive LKPD product based on augmented reality media on chemical equilibrium material that has been developed is interesting for students to study for use in the learning process, especially on chemical equilibrium material.Keywords: LKPD, Augmented Reality, Chemical EquilibriumDOI: 10.23960/jppk.v13i3.32181

Abstract

Research on the slow release kinetics of Fe(III) ions from Activated Carbon/Alginate-Fe(III) composites or abbreviated as K/A-Fe(III) has been carried out. The aim of this research was to synthesize K/A-Fe(III) composite as a material that has the potential to become a slow release micronutrient fertilizer and to study the kinetics of slow release of Fe(III) ions from the composite. The K/A-Fe(III) composite was synthesized by mixing alginate suspension and activated carbon (alginate: activated carbon weight ratio = 1:3 and 3:1) until homogeneous. Composite grains were characterized using Fourier Transformed Infrared (FTIR) spectroscopy, the kinetics of Fe(III) release from the three composite variations found that KAlg31 composite showed more absorption and release of Fe ions than KAlg13.

Abstract

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.

Abstract

Suboptimal classroom instruction can make content difficult to grasp and reduce students’ focus and interest, a problem compounded by the limited use of a learning medium. This study aimed to develop a coconut coir waste–based learning medium (Ecowaste) to improve students’ learning outcomes in Integrated Science and Social Studies (IPAS). We evaluated the feasibility, practicality, and effectiveness of the Ecowaste learning medium in Grade V at SDN 200206 Padangsidimpuan using a Research and Development approach with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Content expert validation reached 92% (“very feasible”), and media expert validation reached 91.4% (“very feasible”). Teacher practicality was 90% (“very practical”), and student responses averaged 86.35% (“very good”). The mean pretest score was 58.25%, increasing to 86.5% on the posttest after using the learning medium, which falls into the “Effective” category. These results indicate that the coconut coir waste–based learning medium (Ecowaste) is feasible, practical, and effective for improving students’ learning outcomes.

Abstract

The integration of 21st-century learning and generic science skills (GSS) is critical in developing students' higher-order thinking skills (HOTS), especially in chemistry education. This quasi-experimental study aimed to analyze the effects of implementing four GSS-integrated digital learning models (PjBL-GSS, PBL-GSS, IBL-GSS, and DL-GSS) and students’ initial abilities on their HOTS performance. A total of 397 students participated, grouped by initial ability levels and assigned to different learning models. Data were collected using validated instruments including scholastic tests and HOTS assessments, and analyzed using descriptive statistics and two-way ANOVA. The results showed significant effects of both initial abilities and learning models on HOTS, with IBL-GSS being the most effective, especially for high-ability students. Moreover, significant interactions were found between initial ability and the type of model used. The study suggests that selecting appropriate digital learning models based on students' prior knowledge is essential to foster optimal HOTS outcomes. Teachers are encouraged to align instructional design with both GSS indicators and students’ learning readiness.

Abstract

The purpose of this study was to design and evaluate the feasibility, usability, and effectiveness of the SIKMAHI (Life Cycle of Living Things) learning media as a tool for teaching IPAS to third-grade elementary school students. The background of this study stems from the low level of students’ interest and learning outcomes related to the topic of life cycles, which is caused by monotonous teaching methods and the limited use of concrete learning media. This research employed a Research and Development (R&D) approach using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research subjects consisted of 18 third-grade students at SDN 060857 Durung. Data were collected through observation, interviews, documentation, questionnaires, and tests (pretest and posttest). Validation results from subject matter experts, media experts, and teachers indicated that the SIKMAHI media is highly feasible for use. Usability testing showed that teachers found the media easy and engaging to apply in the learning process. Furthermore, the pretest and posttest results demonstrated a significant improvement in students’ learning outcomes. In conclusion, the SIKMAHI learning media is effective for use in IPAS learning, particularly for the topic of life cycles of living things. This media is able to enhance students’ understanding, increase learning interest, and encourage active participation in the teaching and learning process.
