Abstract

Air is one of the sources of human life that can be obtained freely. Good or bad air quality can affect human health and activities. The brown sugar production process often causes air pollution that endangers the surrounding environmental conditions. Based on this problem, in this study, an air quality monitoring system and early warning of air pollution were made. This study focuses on air quality monitoring, namely by detecting the level of harmful gases in the air, equipped with a DHT11 sensor to determine temperature and humidity values, and an MQ-135 sensor to determine the content of harmful gases in the air. Then the value of each sensor data is uploaded to the cloud and monitored in real-time using the IoT Platform. The methods used were to design and manufacture hardware and software for monitoring air temperature and humidity and gas content in the air, calibrating the DHT11 sensor, and testing the performance of the MQ-135 sensor as well as testing the overall system performance. The results showed that the calibration of the DHT-11 sensor had an accuracy rate of 99.7% and an error rate of 0.3%, and the MQ-135 sensor was able to detect the gas content in the air optimally. The results of air quality monitoring in the brown sugar production process obtained that the value of the hazardous gas content exposed to the air is 2300 ppm (CO, CO2, NOx, PM10), From the results of this air quality monitoring, the pollutant gases produced from the production of brown sugar are declared to be poor air quality.   This air quality monitoring and air pollution early warning system can provide information about the air conditions around the brown sugar production area in real-time.

Abstract

Manual recording of water meters in the Community-Based Drinking Water and Sanitation Program (PAMSIMAS) is still vulnerable to human error, reporting delays, and operational inefficiencies. This study proposes a smartphone-based Automated Meter Reader (AMR) system that utilizes Optical Character Recognition (OCR) as a low-cost digital solution for rural environments. The system uses a smartphone camera to capture an analog water meter image and processes it through a computer vision pipeline that includes grayscale conversion, bilateral filtering, Canny edge detection, contour-based segmentation, and a full-image OCR fallback mechanism. An experimental evaluation was conducted on 120 analog water meter images with variations in lighting, capture angle, blur level, and meter surface conditions. Digit extraction was performed using Google Vision OCR (online) and Tesseract OCR (offline). The OCR accuracy was calculated based on the compatibility of the digit value of the recognition result with the ground truth value and complemented by confidence score analysis. The test results showed an average OCR accuracy of 91%, a confidence score of 0.87, and an average processing time of 1.27 s per image. Although the system showed stable performance in most test scenarios, the accuracy declined in strong glare conditions and with faulty meters, indicating the limitations of the contour-based segmentation approach. Overall, this smartphone-based AMR system has proven to be feasible and practical for supporting the digitization of community-based water management, with the potential for further development through deep learning-based segmentation.

Abstract

Sektor pertanian masih menjadi penggerak roda perekonomian terbesar di Indonesia. Pekerjaan sebagai petani, juga menjadi mata pencaharian sebagian besar masyarakat di pedesaan. Saat musim panen tiba, berbagai komoditas seperti padi, ketela, jagung dan lainnya melimpah ruah di pasar. Ketersediaan barang yang cukup besar seringkali berdampak pada melemahnya harga barang. Perlu dilakukan diversifikasi produk dengan mengolah hasil pertanian menjadi produk akhir, bukan lagi barang mentah. Tujuan program ini memberikan ketrampilan wirausaha memproduksi popcorn dan bantuan teknologi tepat guna kepada kelompok sasaran produktif. Tahapan pelaksanaan program dilakukan melalui sosialisasi memberikan pemahaman pentingnya menggerakkan potensi desa, melakukan praktek kerja dengan memproduksi bahan baku jagung menjadi popcorn dan memberikan bantuan teknologi teknologi tepat guna POKER ( Popcorn Maker ). Fokus permasalahan adalah penerapan teknologi pasca panen utnuk meningkatkan nilai tambah komoditas jagung dan pembekalan ketrampilan wirausaha masyarakat. Program ini mampu menggerakkan potensi desa dari sektor pertanian, membangun wirausaha baru,meningkatkan nilai jual komoditas pertanian dan akhirnya berdampak pada peningkatan waktu produktif dan pendapatan bagi kesejahteraan masyarakat.

Abstract

Administrative processes have gradually shifted from manual methods to computerized ones in various public services for the community. The service team then made observations in Kaliwungu village and found that the need for computerized data and information processing was still very lacking. Therefore, the Service Team is trying to implement the system that has been implemented in Janggalan and in 11 villages in Mejobo sub-district. This system covers various aspects of data processing, including population data, family facilities and infrastructure, socio-economic conditions, access to education, and others. This system is expected to bridge the needs of village governments in managing data and information as well as in reporting to local governments. This system is expected to be able to support reporting to local governments by presenting and providing data recapitulation with appropriate indicators. Implementation of this system is carried out through training and mentoring methods for village government staff in Kaliwungu, which will then be passed on to the community.

Abstract

Flooding is one of the most frequent natural disasters occurring in the Kesambi River area, causing both material and non-material losses. The delay in obtaining information related to rising water levels is a major factor contributing to low community preparedness. This study aims to design and implement an Internet of Things (IoT)-based Flood Early Warning System (EWS) capable of real-time monitoring in flood-prone areas of the Kesambi River. The method used includes hardware design utilizing an ultrasonic-based water level sensor, microcontroller, and communication module for data transmission, as well as software design in the form of a mobile-based monitoring application. The system operates by detecting changes in water level and transmitting data to an IoT platform for real-time visualization and early warning notifications to users. The testing results indicate that the system can measure water levels with good accuracy and transmit data reliably. Furthermore, the system is capable of providing rapid early warnings when the water level reaches a predefined threshold. Therefore, the developed system can improve community preparedness in facing potential floods and reduce the resulting impacts.

Abstract

Bawang hitam merupakan produk olahan dari bawang putih yang memiliki banyak manfaat kesehatan dan nilai jual yang tinggi. Proses pembuatan bawang hitam memerlukan kondisi suhu, kelembapan, dan berat yang tepat untuk mencapai kualitas yang optimal. Namun, banyak petani yang masih menggunakan metode konvensional dalam proses fermentasi, yang sering kali mengakibatkan hasil yang tidak konsisten dan kurang efisien. Oleh karena itu, diperlukan sebuah sistem yang dapat memantau parameter-parameter tersebut secara otomatis. Penelitian ini bertujuan untuk membuat alat monitoring suhu, kelembapan, dan berat pada proses pembuatan bawang hitam berbasis Internet of Things (IoT). Dengan menggunakan mikrokontroler Arduino dan ESP32, sistem ini dapat mengumpulkan data dari sensor NTC Thermistor, DHT22, dan Load Cell, serta mengirimkan informasi tersebut ke database Firebase untuk pemantauan secara real-time. Aplikasi yang dikembangkan menggunakan MIT App Inventor memungkinkan pengguna untuk memantau kondisi fermentasi dari jarak jauh. Hasil penelitian menunjukkan bahwa sistem monitoring yang dirancang dapat berfungsi dengan baik, dengan tingkat akurasi sensor mencapai 98,8% untuk suhu, 97,2% untuk kelembapan, dan 96,06% untuk berat. Dengan adanya sistem ini, diharapkan proses pembuatan bawang hitam dapat dilakukan dengan lebih efisien dan menghasilkan produk yang berkualitas tinggi.
