Tangerang is counted among Indonesia's fastest-growing industries and population since it is located near the capital. At the current rate of population growth, the population by 2035 is expected to reach more than 2 million by appliying the geometric method. Rapid population growth has severe environmental damage. A simple linear regression calculation was applied to predict the Tangerang waste generation and it is expected to grow to 1,57 million tonnes by 2035. The Pearson's correlation was used to examine the impact of population growth in Tangerang on waste generation. Overall, there is a positive correlation between population growth and waste generation. The increase in the amount of waste can affect the formation of leachate. Rawa Kucing is the main Tangerang landfill that implements an open dumping system in its waste management. One of the negative impacts of the open dumping system is the potential for leachate generation. This study performed a simple calculation of leachate volume to illustrate leachate generation in Rawa Kucing. The more leachate produced, the greater the level of contamination since it contains highly toxic components, and it will escape from the Rawa Kucing landfill, contaminating the groundwater, potentially polluting the environment and harming human health.

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.

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.

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.
