Abstract

Excessive exposure to X-ray radiation can be harmful to human health; therefore, it is important to regularly monitor its intensity, especially in laboratories equipped with ionizing radiation facilities. This research aims to develop an X-ray radiation monitoring system designed to measure radiation levels in the Material Characterization Unit of the Physics Laboratory at Universitas Negeri Semarang. The research method refers to the prototype model, which consists of several stages: communication, quick planning, quick design modeling, and prototype construction. This monitoring system is essential due to the presence of an X-Ray Diffractometer (XRD) machine, which serves as a source of ionizing radiation.The developed system consists of an X-ray radiation detector integrated with an ESP32 microcontroller that transmits data to a cloud server via a Wi-Fi protocol. The radiation detector used in this monitoring system is a Geiger-Müller counter. The measured radiation data can also be displayed on an OLED 128x64 screen. Data acquisition is recorded online using the Google Sheets Application Programming Interface (API), enabling real-time data logging. Experimental results of radiation measurements inside the XRD unit show a radiation dose of 319.2 µSv at a distance of 30 cm from the tube at an angle of 30°, while environmental radiation measurements indicate a dose of 0.815 µSv. The monitoring system’s measurements were compared with those obtained from a standard survey meter, Ludlum Model 3. The results demonstrate that the developed system is capable of measuring X-ray radiation in real-time and can be effectively used for X-ray radiation monitoring.

Abstract

This activity was motivated by the fact that Semarang district was declared by the National Disaster Management Agency (BPBN) as a drought-prone area. Plumutan Village became one of the villages in the Bancak sub-district, Semarang district in 2019 .. The methods used are lectures, discussions, and training. For training on the use of appropriate technology, Dowsing and Geoelectricity is carried out in practice in a predetermined location. The results of the activity showed that the participant's experience increased by being given the practice of making and using dowsing to obtain initial information on the position of areas that have groundwater potential, and experience in using geolistic tools assisted by the service team in several locations that had been determined by the Dowsing tool. The results of geoelectric measurements are then processed using the IP2Win device to obtain a cross-sectional map of the soil layer which shows that at point 1 the depth of the aquifer is 87.4 m and point 2 is at a depth of 83.6 m.

Abstract

Kemambang Village, located in Banyubiru District, Semarang Regency, is highly susceptible to landslides due to its hilly topography and high rainfall intensity. Preliminary observations and discussions with village officials and community representatives indicated that many residents had limited understanding of how to interpret climate and weather information issued by the Meteorology, Climatology, and Geophysics Agency (BMKG) for landslide preparedness. This community service program aimed to develop a community-based landslide early warning system by integrating climate and weather information with participatory education, scenario-based simulations, and digital communication through the “Masyarakat Pemerhati BMKG” WhatsApp group. The program was conducted on July 26, 2025, at the Kemambang Village Hall, Banyubiru District, Semarang Regency, involving 25 participants consisting of village officials, community representatives, and local stakeholders. Program evaluation was conducted using pretest-posttest assessments and a reflective questionnaire. The average pretest score increased from 28.42 to 32.32 in the posttest, indicating an improvement in participants’ short-term understanding after the program. Reflective questionnaire results further showed that 84% of participants demonstrated adequate understanding of the training materials, 72% had previous disaster experience, 51% exhibited environmental awareness, and 93% expressed interest in participating in follow-up disaster mitigation activities. The WhatsApp group was established as a community communication platform for disseminating official BMKG weather information and supporting continuous disaster preparedness after the training. In addition, educational videos and disaster mitigation posters were developed to strengthen public awareness. These findings indicate that integrating climate and weather information with participatory education, community-based communication, and digital follow-up can improve short-term community understanding and support the development of a sustainable community-based landslide early warning system in Kemambang Village.
