The Merdeka curriculum organizes the physics subject into concept understanding and science process skills. However, based on interviews and observations at MAN IC Pekalongan, the development of process skills in physics learning is rarely facilitated due to the limited availability of learning media and time. This RnD research aims to develop digital learning media as an alternative solution to these problems. The analysis of learning media needs showed that teachers and students need Interactive E-Modules as learning media, applications of physics in everyday life such as STEM, and a Virtual Lab packaged with interactive and simple language. The E-Module was validated by several experts in material, learning media, and learning and was declared highly feasible with an average score of 4.5 out of 5. The posttest results showed an average score of 59.67 for both the experimental and control classes. The n-gain analysis demonstrated that the E-Module effectively improved conceptual understanding, with an n-gain value of 0.74 (high), and had a positive effect on process skills with an average value of 87.86 for the experimental class and 86.44 for the control class, with a significance value of 0.032 in the independent sample test of both classes.

Telkomsel has introduced 5G technology in Padang City, evaluated through drive tests using G-Nettrack Pro software to measure Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR). The tests revealed RSRP values ranging from -44 dBm to -100 dBm and SINR values between -12 dB and 26 dB. While high RSRP does not always guarantee high throughput, higher SINR consistently improves throughput, with the highest throughput reaching 153,053 kbps at SINR levels between 10 and 30 dB. Modulation and Carrier Aggregation (CA) also play a significant role, with 64-QAM modulation combined with CA achieving throughput up to 31,500 kbps, compared to 6,300 kbps without CA. Although CA bandwidth decreased from 100 MHz to 50 MHz, throughput remains higher compared to 20 MHz bandwidth without CA. CA proves highly effective in enhancing throughput through larger bandwidth and more efficient modulation. Additional factors such as handover, interference, and physical and weather conditions also impact network performance. Overall, Telkomsel’s 5G network in Padang City meets the company’s Key Performance Indicators (KPI), despite some areas with suboptimal signal quality.
