Nobita Hill, a tourist site in Padang City, is undergoing development as a tourist destination that offers a bird's-eye view of Padang City. Unfortunately, the hilly topography with steep slopes increases the risk of landslides in this area. In order to address the problem, the community service team from the Physics Department of Andalas University has carried out a six-month community service program from July to December 2022. It focused on disaster awareness education and used a qualitative approach. This activity aims to socialize disaster mitigation efforts, especially those related to landslides and earthquakes, considering that Padang City is also prone to earthquakes. The results of this activity showed an increase in the knowledge of the local community after the socialization, but repeated activities are needed to achieve optimal results. This ongoing activity is essential to ensure continuous improvement in the community's understanding of disaster mitigation and to support efforts to make Bukit Nobita a disaster-resilient area. Thus, this activity makes a positive contribution to shaping a safe, sustainable, and disaster-resilient tourism environment.

This research was conducted to determine the distribution of magnetic anomalies in the geothermal area of Nagari Cupak, Solok Regency using geomagnetic methods. Data was collected using a magnetometer at 144 observation points with a distance of 300 m between points. The magnetic anomaly value is obtained from the correction of daily variation’s total magnetic data and correction to the magnetic field value of the 13th generation IGRF (International Geomagnetic Reference Field) reference model. Furthermore, reduction to the poles and continuation upwards with a height of 200 m are carried out to remove noise and separate local and regional magnetic anomalies. After data processing, the total magnetic anomaly value in the area ranges from 1252.8 nT to 2969.4 nT which is categorized as low. The low anomaly value is thought to be caused by the demagnetization of rocks due to the influence of geothermal sources in the subsurface. Furthermore, 2D modeling is carried out by analyzing the magnetic anomaly data and making a cross-sectional incision of the model on the contour of the magnetic field anomaly that has been processed above. Based on the modeling results, the subsurface geothermal system of Nagari Cupak, Solok Regency, consists of a cover rock layer, reservoir layer, and hot rock layer which is suspected to be the heat source of the geothermal system of the study area.

A study was conducted to investigate the effect of varying concentrations of cocoa leaf extract on ZnO nanoparticles as a capping agent. The concentrations of cocoa leaf extract were varied at 0%, 2%, 4%, 6%, and 8%, and tested to observe their effects on crystal size, optical properties, and morphology of the ZnO nanoparticles. The ZnO nanoparticles were synthesized using the sol-gel method with cocoa leaf extract. The success of the synthesis was indicated by the similarity of the peaks from the synthesized compounds to the standard ZnO peaks in the X-Ray Diffraction (XRD) analysis. The resulting crystal structure was hexagonal wurtzite, with crystal sizes for each extract concentration of 54.393 nm, 54.01 nm, 54.39 nm, 45.61 nm, and 38.45 nm, respectively. UV-Vis spectrometer analysis showed that the ZnO nanoparticles were relatively stable at wavelengths between 228 nm and 366 nm, with bandgap energy values for each extract concentration being 3.11 eV, 3.13 eV, 3.11 eV, 3.14 eV, and 3.15 eV, respectively. The UV-Vis results indicated that the bandgap energy increased with increasing concentrations of cocoa leaf extract, while the crystal size decreased, which was consistent with the XRD results. Scanning electron microscope (SEM) analysis showed that ZnO nanoparticles synthesized with 4% cocoa leaf extract predominantly exhibited a spherical shape, with an average size of 45 nm.

Research to identify the level of water quality of Batang Agam River in Payakumbuh City has been conducted based on physical and chemical parameters. Physical parameters in this study are temperature, electrical conductivity, Total Dissolve Solid (TDS), and Total Suspended Solid (TSS). Chemical parameters in this study are acidity (pH) and heavy metals in the form of cadmium (Cd), lead (Pb), and zinc (Zn). The level of river water pollution is processed using the Pollution Index (IP) method and analyzed based on the class I quality standard of Government Regulation No. 22 of 2021. The results of this study obtained that the temperature value of the Batang Agam River in Payakumbuh City in the Sumatra Region Balai Park (TBWS) area exceeds the quality standard value of 30.33⁰C. The pH and TDS values are still within the quality standard threshold of 6-9 and 1000 ppm respectively. The TSS value has exceeded the quality standard value of 40 ppm. The electrical conductivity value is still within the quality standard according to the World Health Organization (WHO) 2017 of 1500 µs/cm. The concentrations of heavy metals Cd, Pb, and Zn were 0.0495 mg/L, 0.0325 mg/L, and 0.0254 mg/L, respectively, with Cd and Pb concentrations exceeding the quality standard. Based on the measurement of water quality parameters, it is concluded that the level of pollution of the Batang Agam River in Payakumbuh City is classified as lightly polluted with an average IP value of 4.61, which cannot be used for drinking water and household purposes.
