Abstract

Abstrak: Perkembangan teknologi dalam sektor pertanian membuat para petani harus mampu beradaptasi dengan teknologi yang dapat digunakan untuk membantu pekerjaan menjadi lebih efektif dan efisien. Perkembangan teknologi yang dimaksud salah satunya menggantikan system manual menjadi system otomatisasi. Contoh system otomatisasi yang dapat dipakai oleh petani adalah penyiram tanaman. Namun Saat ini masih banyak petani melakukan penyiraman tanaman secara manual manual, yaitu petani harus selalu melihat tanaman untuk melakukan penyiraman langsung. Hal ini sering dianggap kurang efisien dan efektif karena petani tidak punya cukup waktu untuk menyiram tanaman, serta kurang mengetahui berapa banyak air yang dibutuhkan oleh tanaman. Jika Tanaman tidak disiram tepat waktu dapat dipastikan tanaman menjadi layu dan akhirnya tanaman bisa mati. Berdasarkan permasalahan yang terjadi, penulis mengembangkan sebuah sistem otomatisasi yang dapat membantu petani melakukan penyiraman tanaman secara otomatis. Pada sistem otomatisasi yang dibangun menggunakan Mikrokontroller Arduino Uno sebagai pengontrol utama, Sensor kelembaban tanah Capasitive Soil Moisture sebagai sensor untuk mengetahui kelembaban tanah. Motor DC L298N akan digunakan untuk mengatur Pompa mini DC untuk mengalirkan air ke tanaman berdasarkan hasil pembacaan dari sensor kelembaban. LCD I2C sebagai monitor untuk melihat hasil pembacaan sensor kelembaban. Setelah pengembangan sistem otomatisasi ini diharapkan dapat berjalan dengan baik dan digunakan petani untuk melakukan penyiraman tanaman mereka sehingga tanaman dapat dipantau pertumbuhannya

Abstract

Internet of Things (IoT) technology can enhance agricultural productivity through automated monitoring and control systems. However, many existing IoT systems are still centralized and inflexible, making integration with other systems in the field challenging. This research develops a distributed and modular (plugin) automated monitoring and control system for soil moisture management, specifically for potato cultivation. The system utilizes soil moisture sensors to measure moisture levels, which are processed by an ESP8266 microcontroller. The data is used to automatically control irrigation flow, maintaining soil moisture within the optimal range for potato plants. Additionally, the system includes a backup feature that allows manual operation in case of automatic system failure. Field tests demonstrate that the system effectively maintains soil moisture at optimal levels. Its manual operation feature also ensures continued functionality during disruptions. Therefore, this system is expected to improve efficiency and resilience in agricultural land management, particularly in dynamic environmental conditions.

Abstract

Rice is an important commodity for human life. The application of appropriate technology continues to be developed and researched as an effort to create food security. Indonesia is one of the largest rice producers but has not fully implemented agricultural technology. The lack of application of technology causes agricultural techniques to be still traditional. This causes the younger generation to be less interested in working as farmers. One of the challenges for novice farmers is how to handle plant diseases. This study aims to design a disease detection system so that it can be easier to handle. This plant detection uses a deep learning method with the YOLO V5 Algorithm. To obtain the best model, each YOLO V5 version was compared. The experimental results showed that the detection of healthy plants could be predicted better (0.99) than the other classes. Based on the predicted value, it means that the extra-large version is better (0.83) than the other versions. In addition, this study also designed the user interface with website application media. This website can be accessed via a laptop or smartphone so that its use is more effective and efficient. The user interface design is designed simply so that farmers and novices can easily learn and use it. With this research, it is hoped that rice production can be increased and one way to attract the interest of the younger generation.

Abstract

The socialisation of understanding digital attacks aims to help the community, especially students in the Toba area, regarding the types of digital attacks and how to deal with them. The socialisation activity was conducted in several junior high and senior high schools in Toba. Socialisation was also carried out to help the students understand the types of digital attacks by questionnaire. The contents of the questionnaire were to see how large the percentage of digital attacks, such as identity forgery, phishing, and data leaks, were experienced by students. The results of 315 respondents showed that digital attacks were in the "Normal" category of 18.88%, "Often" 29.33%, and "Very Often" 17.73% of respondents. The cases were attacks on personal information, defamation, hacking of social media accounts, data breaches, online fraud, the spread of hoaxes or disinformation and cyberbullying.

Abstract

In this ever-evolving digital age, container technology has become one of the main solutions in cloud computing due to its efficiency and flexibility. However, the dynamic and ephemeral nature of containers poses new challenges in terms of security, especially regarding data integrity. The implementation of OSSEC in container environments requires a tailored approach, as it lacks native support for automatically detecting new containers. Agents must be embedded within container images or installed at the host level. These agents activate each time a container runs and send monitoring data to the OSSEC server. With orchestration and automated configuration, monitoring results are stored externally, and real-time email alerts can be triggered upon detecting suspicious file changes. Container environments are increasingly targeted by cyber threats such as malware and ransomware, which pose risks of unauthorized data access or encryption. Limited file integrity monitoring within containers creates a security gap that can be exploited undetected. This research addresses the issue by implementing a File Integrity Monitoring (FIM) mechanism using OSSEC, an open-source Host Intrusion Detection System (HIDS) capable of real-time file and log monitoring, malware detection, and automated threat response. OSSEC is deployed within a Docker-based setup and integrated with a Web User Interface for visualizing logs and monitoring activity. The system includes real-time email notifications for immediate alerts. Testing through file modification scenarios confirmed OSSEC’s accuracy in detecting changes and notifying administrators. This implementation effectively strengthens data security and provides timely threat detection in containerized environments.

Abstract

Infusion is a common medical procedure used to treat conditions such as gastric acid and typhoid, where precise fluid administration is critical. This study presents the development of an IoT-based smart infusion monitoring and control system using an ESP32 microcontroller, designed to automatically monitor infusion volume and regulate drip rate in real-time. The system integrates a load cell sensor to measure infusion fluid weight, a photodiode sensor to detect drip rate, and a servo motor to adjust the flow rate adaptively. It features web-based monitoring, buzzer alerts, and an LCD display for local feedback. The system was tested in a clinical simulation with an infusion requirement of 1500 mL per 24 hours and various drip factors (15, 20, and 60 drops/mL). The infusion volume status is automatically categorized into three levels: FULL (>350 mL), HALF (150–350 mL), and WARNING (<150 mL). Based on 10 test scenarios, the system accurately classified volume levels and triggered warnings when volume dropped below 150 mL. For example, in Test-08 to Test-10, volumes of 139.67 mL, 87.34 mL, and 40.53 mL were correctly detected as “WARNING” with buzzer alerts activated. The load cell sensor achieved excellent accuracy, with an error margin between 0.02% and 0.06%, while the system maintained drip-rate stability within a ±5% tolerance range. It also dynamically adjusted the servo angle to correct under- or over-drip conditions. These results confirm that the system delivers accurate, automated, and responsive infusion control, making it suitable for healthcare settings with limited staff to improve safety and efficiency.
