Abstract

The preparation of a digital village map is one form of utilizing information technology to support regional data management and development planning at the village level. Wanasaba Daya Village, located in Wanasaba District, East Lombok Regency, requires geographic data that are presented systematically and easily understood. So far, information related to administrative boundaries, road networks, settlements, and public facilities has not been fully documented in an integrated digital map. This study aims to develop a digital village map of Wanasaba Daya Village by utilizing a Geographic Information System (GIS) using ArcGIS software. The method applied is descriptive, with secondary data collection obtained from online sources, particularly the LapakGIS website, and adjustments based on field observations. Spatial data were processed and presented in several layers representing the main elements of the village area. The results indicate that the resulting digital village map is able to present geographic information in a more structured and informative manner. This digital village map is expected to be utilized by the village government as a supporting medium for regional data management, development planning, and as part of efforts to digitalize village administration

Abstract

Indonesia is an agrarian country where the agricultural sector plays an important role in supporting the national economy. However, agricultural land management is still largely carried out using conventional methods, resulting in suboptimal monitoring of soil nutrient conditions. Nitrogen (N), Phosphorus (P), Potassium (K), and soil acidity (pH) are critical parameters influencing soil fertility and crop productivity. This study aims to develop a soil monitoring system for NPK and pH levels based on Artificial Intelligence (AI) and the Internet of Things (IoT) using an NPK Modbus sensor, an analog soil pH sensor, and an ESP32 microcontroller. Sensor data are transmitted in real-time to a Firebase database via a Wi-Fi network and displayed on a web dashboard through numerical visualizations, graphs, and ChatGPT-based AI analytic interpretations. The experimental results show that the system successfully acquires and transmits soil condition data consistently. Accuracy testing demonstrated that the system is highly precise, with the pH sensor readings showing an average difference (error rate) of only 0.2% when compared to a standard pH tester. The NPK sensor also exhibited excellent reactivity to changes in soil macronutrients. Furthermore, the integrated AI system successfully provided stable fertility evaluations and fertilization recommendations across multiple repeated tests. This system is expected to facilitate remote field monitoring for farmers and support precise, efficient fertilization decision-making.

Abstract

Monitoring temperature and air quality are important factors in creating a comfortable and safe treatment room environment for patients. This study aims to design and implement an Internet of Things (IoT)-based temperature and air quality monitoring system integrated with automatic blower control. The system was developed using the Research and Development (R&D) method by utilizing a DHT22 sensor for temperature and humidity measurement and an MQ135 sensor for air quality detection, controlled by NodeMCU ESP8266. The system was tested by comparing the temperature sensor readings with a thermohygrometer and testing the system's response to changes in environmental conditions. The test results showed that the system was able to monitor temperature and air quality in real-time with a temperature measurement error rate of 0.21% and was able to activate the blower automatically when the temperature and air quality values exceeded the specified thresholds. Thus, the developed system proved to work well and can be used as an IoT-based environmental monitoring solution for treatment rooms.
