Abstract

The development of computer vision technology and artificial intelligence has driven innovation in automation in various fields, including the agricultural sector and fruit trading. The process of identifying fruit quality, which is generally done manually, is still vulnerable to human error and inconsistencies. Based on these problems, this study aims to develop an automated system to detect the difference between fresh and rotten fruit using a deep learning-based You Only Look Once (YOLO) algorithm integrated with the OpenCV library. The system is designed in the form of a web application that is easy for fruit sellers to use. The dataset used consists of images of apples, mangoes, and bananas labeled through Roboflow into two categories, namely fresh and rotten. The model was trained using YOLOv11, then tested with new data that had never been used before. The test results showed high performance with an accuracy of 99.01%, mAP@50 of 0.925, precision of 0.93, recall of 0.90, and F1-score of 0.91. Based on these results, the system is able to detect the condition of the fruit automatically and in real-time with an excellent level of accuracy. This implementation proves that the integration between YOLO and OpenCV is effective in improving the efficiency, accuracy, and consistency of the fruit quality identification process.

Abstract

The development of Internet of Things (IoT) technology has had a significant impact in various fields, including the agricultural sector. One of the main challenges in modern agriculture is the efficient and accurate measurement of soil fertility, including temperature, humidity, and nutrient content parameters such as nitrogen (N), phosphorus (P), and potassium (K). Manual measurements take considerable time, effort, and cost, and often result in less accurate data because they are subjective and not real-time. This research aims to design and build an IoT-based soil fertility measuring device that integrates NPK sensors, Soil Moisture sensors, and DHT22 sensors with ESP32 microcontrollers as the system control center. The methods used include hardware and software design, ESP32 programming using Arduino IDE, and integration with the Firebase platform for online data storage. It reads the soil conditions in real-time and displays the measurement results on the LCD, as well as transmitting data to a smartphone application over the internet. The test results show that the tool can distinguish fertile and infertile soil conditions well. In fertile soils, a temperature of 29°C, humidity of 89%, and NPK content of Nitrogen 20–23 ppm, Phosphorus 32 ppm, and Potassium 190–195 ppm, respectively. Meanwhile, in infertile soils, a temperature of 23–32°C, humidity below 75%, and a Nitrogen content of 12 ppm, Phosphorus 22 ppm, and Potassium 118–120 ppm. This system provides benefits in remote monitoring, resource efficiency, and increased agricultural productivity.

Abstract

Alphabet recognition is an essential skill in students' development; therefore, it requires greater attention from parents and teachers. This study aims to determine the effect of plasticine media on letter recognition in early childhood at Baiturrahman Sako Islamic Kindergarten, Palembang. This study uses a quantitative approach with a one-group pretest-posttest design and involves 15 children as samples selected by the purposive sampling method. The instrument used is an observation sheet that has been tested for validity and reliability with valid and reliable results. The research procedure includes administering a pretest and providing treatment through plasticine-based learning. A posttest was administered to assess treatment outcomes; the data were analyzed using a t-test, which showed a significant increase in scores (p < 0.001). These results demonstrate that plasticine media affect letter recognition in children aged 4-5 years.

Abstract

Narcotics offenses constitute serious violations under the Code of Ethics of the Indonesian National Police (KEPP). Accordingly, police officers who are proven to have committed such criminal acts and whose cases have been decided by a court with final and binding legal force may be subsequently recommended to receive administrative sanctions in the form of Dishonorable Discharge (PTDH). The purpose of this study is to analyze the legal regulation of ethical and disciplinary responsibility of police officers involved in narcotics abuse at the Pulau Meranti Police Resort. This research employs a sociological legal research method. Based on the research findings, it is evident that the involvement of police officers in narcotics abuse constitutes a serious violation with multilayered legal implications, encompassing criminal liability, disciplinary sanctions, and professional ethical responsibility. Members of the Indonesian National Police are bound by legal and moral obligations to uphold the law, adhere to professional ethics, and maintain the honor and dignity of the police institution, as mandated by Law Number 2 of 2002 on the Indonesian National Police, Government Regulation Number 2 of 2003 concerning Police Disciplinary Regulations, and Regulation of the Chief of the Indonesian National Police Number 7 of 2022 on the Police Professional Code of Ethics. However, this study also reveals that cases involving police officers in narcotics abuse continue to occur annually, including within the jurisdiction of the Pulau Meranti Police Resort. As a result, the persistence of such violations underscores that the enforcement of ethical and disciplinary sanctions has tended to be repressive in nature and has not fully addressed preventive and comprehensive guidance aspects.
