Abstract

Kalisalak Hamlet in Sukoharjo District is faced with the risk of landslides that can affect the structure of residents' houses. This study aims to identify potential landslide zones based on the parameters of Dominant Frequency (f_0), Amplification Factor (A_0), and Seismic Vulnerability (K_g)to determine areas that are potentially vulnerable to landslides. Microseismic measurements were carried out at 25 measurement points in the landslide zone. Measurements used a 3-component digital portable seismograph (North-South, West-East, and Vertical). Microseismic data were processed using Geopsy software with the HVSR (Horizontal-to-Vertical Spectral Ratio) method to obtain an H/V curve that provides Dominant Frequency (f_0) and Amplification Factor (A_0) values. The results showed that Kalisalak Village has a dominant frequency value between 3 Hz to 12.5 Hz and an amplification factor value between 1.4 to 6.8. This variation indicates that some areas are more susceptible to seismic vibration amplification. Based on the Dominant Frequency (f_0) value and Amplification Factor (A_0), a Seismic Vulnerability (K_g) microzonation map was created for Kalisalak hamlet with a value range of 0.2 to 7 with a high vulnerability value located in the landslide area south of the village. This map is important for disaster mitigation planning in Kalisalak hamlet.

Abstract

Besei Kambe is a traditional Dayak game from Central Kalimantan in which two teams compete by pulling a jukung on the water. Beyond its cultural significance, this activity embodies various physics concepts that can be utilized as contextual learning resources. This study aims to identify and analyze the physical principles that emerge during the practice of Besei Kambe, particularly those related to Newton’s laws, action–reaction forces, and resultant forces. Through qualitative analysis based on illustrative observation and literature review, the study reveals that the motion dynamics of the boat and the interactions between the paddlers and the water reflect direct applications of these fundamental physics concepts. These findings indicate Newton’s First Law appears when the boat remains still under balanced forces, Newton’s Second Law when an unbalanced force causes acceleration, and Newton’s Third Law in the action–reaction interaction between the paddle and the water. These findings demonstrate that Besei Kambe naturally represents fundamental mechanics principles and can serve as an effective contextual resource for physics learning grounded in local wisdom.

Abstract

Kelurahan Mangunsari is located at Semarang city and emerges as a locale brimming with potential, yet grappling with the pervasive challenge of waste management, a predicament shared by many urban areas. This neighborhood faces the daunting task of dealing with both organic and inorganic waste, wherein the latter has seen some resolution through the establishment of a waste bank in RW 04. However, the management of organic household waste remains a critical issue. Addressing this, the Community Empowerment Team (PkM) from Universitas Negeri Semarang (Unnes) has embarked on a pioneering mission to imbue the local populace with the knowledge and skills necessary to transform waste into valuable resources, namely compost and ecoenzymes. This endeavor unfolds in three strategic phases: an educational campaign on waste management principles, hands-on training in compost and ecoenzyme production, and a rigorous monitoring phase to evaluate the program's efficacy. The initiative's results are commendable, marking a significant milestone in community-led waste management practices. Not only has it been successful in producing compost and ecoenzymes, but it has also fundamentally shifted the community's perception, recognizing the initiative as a transformative tool for enhancing household waste management. This case study not only underscores the potential of community empowerment in environmental stewardship but also serves as a replicable model for sustainable urban waste management solutions.

Abstract

This study aims to implement a differentiated Project-Based Learning (PjBL) model to improve students' science process skills and scientific attitudes in the topic of renewable energy. A quasi-experimental method with a pretest-posttest control group design was applied. The experimental class was taught using the differentiated PjBL model, while the control class used conventional PjBL. Instruments included open-ended tests to assess science process skills and Likert-scale questionnaires to evaluate scientific attitudes. The results showed a significant improvement in all science process skill indicators and scientific attitudes in the experimental class compared to the control group. Skills such as observing, questioning and predicting, conducting investigations, processing and analyzing data and information, evaluating and reflecting, as well as communicating results improved evenly across the board. Regression analysis indicated that science process skills positively influenced scientific attitudes, contributing 11.8% of the variance. These findings highlight the effectiveness of differentiated PjBL in offering more personalized and contextual learning experiences that develop both cognitive and affective student outcomes. Physics teachers are encouraged to integrate this model into classroom practice and to enhance their competence in designing student-centered project learning. Future studies may explore its application across different subjects and education levels to broaden its impact.

Abstract

Physics learning on non-central collisions is often challenging because students must understand abstract concepts and dynamic interactions, while existing instructional Material generally provide limited opportunities for conceptual exploration and problem-solving. To address this issue, this study developed instructional Material based on the Problem-Based Learning model supported by PhET simulations. This study aims to identify the characteristics, level of suitability, and student responses to the developed instructional Material. This study employs a Research and Development (R&D) method using the 4D model, which includes the Define, Design, Develop, and Disseminate stages. The research instruments included expert validation sheet, readability test sheets, and student response questionnaire. The results showed that the developed instructional Material integrated the PBL framework with PhET simulations, enabling students to solve contextual problems, explore concepts, and build understanding independently. The feasibility test yielded a score of 91.25%, categorized as “highly feasible” based on content, presentation, language, typography, and visual design. The readability feasibility test obtained 91.79%, categorized as “highly feasible,” while student readability reached 98%, categorized as “easy to understand.” Student feedback on the use of these instructional Material reached 89.5%, categorized as “very good.” Based on these results, the developed instructional Material have strong potential as an effective learning resource for teaching non-central collisions in physics.
