Abstract

The digital era has brought major changes to the education, including Science learning at the junior high school level. However, science learning at the junior high school level still needs several challenges, such as a lack of variety in learning media, low interest in learning science, and limited students' ability to understand science concepts. Based on these problems, the Physics Laboratory of Universitas Trisakti held a Community Service (PkM) activity in collaboration with MGMP IPA of Tangerang. Service activities are carried out in the form of training for science teachers with training materials to improve brain memory abilities and training on the digitalization of science learning with ThingLink interactive media. Teachers are often faced with various challenges in teaching, including the complexity of science material, the rapid development of science and the high workload of teachers. Training to improve brain memory abilities can help improve teachers' ability to remember information, focus and concentrate. Furthermore, training on digitizing science learning using ThingLink is considered important to carry out. ThingLink is a digital platform that allows the creation of interactive science learning content, simulations and virtual experiments that are interesting and easy for students to understand. This PkM activity can increase teacher competency and professionalism in teaching, so that it can improve the quality of science learning in the classroom. This training can be carried out sustainably by collaborating with more educational partners.

Abstract

The self-potential (SP) method investigated leachate distribution near Rawa Kucing. Rawa Kucing is the main landfill in Tangerang that burned almost the entire area. A total of 78 SP data points were scattered throughout the study area. The SP values range from -20 to 16 millivolts, dominated by negative values attributed to electrokinetic processes. The results suggest that a highly conductive zone in the study area may have been caused by high contamination from leachate. The possible direction of leachate flow is towards the Cisadane stream, located west of the landfill. On the other hand, a quantitative interpretation of SP was conducted for two profiles, AA’ and BB’. The result shows that the vertical spreading of leachate was found at a depth of h 6,59 and 3,53 meters and H 8,10 and 4,34 meters for AA' and BB', respectively, with an angle of 28,810. Additionally, groundwater samples were collected from four sites near the landfill to assess groundwater quality using physical and chemical analysis. Based on the Indonesian Ministry of Health Regulation, most parameters indicated low contamination. Statistical analysis revealed that the groundwater near the landfill was worthy of consumption. Based on the results, rainfall during the study significantly reduced the concentrations of contaminants in leachate due to dilution.

Abstract

Accuracy in measuring local gravitational acceleration remains a challenge due to the limitations of conventional experimental approaches and the influence of dynamic system conditions. Furthermore, few studies have integrated numerical simulation methods to enhance precision in the context of nonlinear oscillatory motion. This study aims to conduct an in-depth analysis of the dynamics of a damped physical pendulum and to evaluate the accuracy of local gravitational acceleration measurements by integrating experimental methods with numerical simulations. This is a quantitative study employing a quasi-experimental design. The research subject consisted of a single set of physical pendulum apparatus in the form of a homogeneous metal rod, with no human participants involved. Data were collected by measuring the oscillation period using a high-accuracy digital stopwatch and the effective length using a roll meter. Instruments were validated based on classical physics principles and result consistency tests. Numerical simulations were performed using the fourth-order Runge-Kutta method (ODE45). Data analysis included quantitative descriptive analysis, comparative analysis, relative error evaluation, and uncertainty identification. The results showed that the experimental gravitational acceleration value closely approximated the theoretical value, with a low relative error. It is concluded that integrating experimental and simulation approaches provides a more comprehensive understanding of pendulum dynamics and improves the accuracy of local gravity measurements. The findings imply the need for more complex dynamic models to support precision measurements in various fields such as geophysics, engineering, and education.

Abstract

A decline in groundwater quality in the coastal part of Tangerang Regency, which directly borders the Java Sea, has been identified in recent years. This content analysis research examines the suitability of the coast of Tangerang Regency, especially the Kosambi sub-district, as an industrial area based on the RPIJM of the Tangerang Regency government. Groundwater quality and the impact of intrusion in the study area were analyzed based on secondary data obtained from the Groundwater and Subsidence Monitoring System of the Ministry of Energy and Mineral Resources at 15 water sample points. The parameters analyzed include physical, chemical and inorganic water parameters. The results obtained from the analysis of various parameters show that groundwater in the study area is polluted by seawater. The plan to develop an industrial area in the study area will certainly impact increasingly severe levels of intrusion in the study area if the plan does not pay attention to preserving groundwater resources.

Abstract

Research-based elective courses can be an alternative to Student-Centered Learning (SCL) classes. Project-based learning (PjBL) can be an attractive learning method. PjBL was developed through lecturers' research interests to balance the tri dharma of higher education. This study aims to give an example of creating an elective course in an SCL class. Kansei Engineering in Affective Design (KEiAD) class is a PjBL elective course successfully implemented in the Industrial Engineering Department of Universitas Trisakti by appointing the lecturer's research. Course learning outcome (CLO) was developed through five major stages of the KEiAD framework: identifying Kansei users, selecting design concepts, identifying key design elements, formulating design, and prototyping. The first lecture had good results. Eleven groups containing two to three students could formulate 11 affective products. All students also succeeded in achieving the expected outcomes of this course. Several students showed interest in using KEiAD as a final project topic. In the future, a quota for elective courses that is too large, such as 32 students, is considered too large because the assistance in class is not intensive enough. Smaller student quotas and R studio alternatives can be considered for continuous improvement.

Abstract

The effective science education requires practical methods that allow students to explore complex physics concepts. One promising approach is the use of physics experiment as an interactive media. This research focuses on the development of water rocket launcher using an Arduino as an innovative physics experiment. Arduino in water rocket launcher is used for making the precise control and relevant measurement of variables, such as angle of projection, speed of launch, maximum altitude of launch, and air pressure. The research process followed the ADDIE instructional design model and involved hardware, software prototyping, work testing, and user instruction. The launcher’s performance was tested with 33 engineering students and assessed by 5 experts. Expert evaluations rated the relevance, design, and usability of the kit highly (3.4–4.0 on a 4-point Likert scale). User responses from 33 students indicated strong agreement on ease of use and engagement (mean scores 3.79–3.91), with a high reliability (Cronbach’s alpha = .964). Experimental launches, using three and four finned rockets, showed maximum height percentage differences between theoretical and observed values ranging from 0.0%–52.6% (three fins) and 1.2%–51.8% (four fins); range errors were 3.4%–36.8% (three fins) and 2.1%–42.7% (four fins). The findings confirm that the Arduino-based water rocket launcher provides effective, interactive learning, though further refinement in data accuracy and instructional materials is recommended to maximize its classroom impact and is needed for improved accuracy.
