Abstract

Budidaya selada perlu memperhatikan kondisi lingkungan agar pertumbuhannya optimal. Melakukan budidaya di ruangan terkontrol bertujuan agar pertumbuhan tanaman selada selalu stabil tanpa perlu mengkhawatirkan faktor alam. Penelitian ini menggunakan NodeMCU ESP32 sebagai pengendali sistem untuk melakukan pemantauan dan pengontrolan budidaya selada berbasis Internet of Things (IoT). Sensor pH air analog digunakan untuk memantau pH air, sensor capacitive soil moisture untuk memantau kelembapan tanah, dan sensor DHT11 untuk memantau suhu dan kelembapan udara. Pengontrolan kondisi ruang budidaya dapat dilakukan menggunakan sistem berdasarkan parameter pH, kelembapan tanah, kelembapan udara, suhu udara, dan intensitas cahaya yang ideal untuk pertumbuhan tanaman selada. Pengguna juga dapat melakukan pengontrolan secara manual. Hasil pengamatan selama 14 hari menunjukkan bahwa tanaman selada yang dibudidayakan berbasis sistem mengalami pertumbuhan yang subur sebesar 60% dan pertumbuhan sedang sebesar 40%. Tanaman selada yang dibudidayakan secara manual hanya mengalami pertumbuhan yang subur sebesar 10%, pertumbuhan sedang sebesar 10%, pertumbuhan kurang sebesar 30% dan sudah tidak mengalami pertumbuhan lagi karena layu atau mati sebesar 50%. Faktor yang memberikan pengaruh signifikan terhadap kesuburan budidaya tanaman selada adalah intensitas cahaya dan kelembapan tanah.

Abstract

Server security is an important thing that must be considered so that the server can work well and serve users. Attacks on servers can threaten server performance and data security in it. According to the National Cyber and Crypto Agency 2020 report, ports 22 and 80 were the top ports with the most attacks. One of the attacks on port 22 is brute force and an attack on port 80 is Distributed Denial of Service (DDoS). To solve this problem, a study was conducted to implement fail2ban IPS (Intrusion Prevention System) to increase server security. The attacks tested focused on brute force attacks on port 22 and DDoS attacks on port 80 using the TCP protocol. The fail2ban system is equipped with a website interface and notifications via telegram. The test results show that DDoS attacks have more impact on CPU performance with the highest increase in CPU being 92%, while brute force attacks have more impact on server memory performance with the highest increase in memory by 100%. The increase in server performance results in slowed server performance. The system managed to prevent DDoS attacks with an average speed of 0.5 seconds while brute force attacks were 6.1 seconds. The system managed to prevent DDoS attacks with a total of 88 attacks and brute force attacks with a total of 864 attacks.

Abstract

Server is a center for providing services and storing data in a computer network. A server is managed by server administrator who has a duty of monitoring security server. While on duty, there are deficiencies in detecting attacks, the slow information about the attacks, and how to handle attacks on the server. In this research, a server security system was created by implementing an Intrusion Prevention System (IPS) based on website and mobile applications. Attack detection focuses on ICMP and TCP port attacks with the latency time when the system responds to an attack is 99,89 ms (very good). The attack handling system was successfully carried out using Iptables against the attacker's IP that detected by the Suricata system through the website and mobile applications, to be given action which is divided into Drop, Reject and Accept. Administrators can quickly take the necessary precautions after receiving an automatic notification when the server is under attack via Telegram with an average speed is 3.41second. The ping attack, port scanning and ping of death (DoS) attacks resulted in an increase in the performance load on the local server with the initial conditions of CPU performance ranging from 10-19%, increasing when a ping attack occurred to 21,6%, memory 41,7%, and disk 19,6%. Port scanning increased by 85,9% CPU, memory 41,9%, and disk 20,3%. Ping of death increased CPU 90,4%, memory 42,9%, and disk 20,8%. Based on the tests that have been done, an excessive increase is found in the ping of death attack which results in server performance increasing to 90,4%, if the attack occurs for a long time then the server condition will be hang (damaged).

Abstract

Aeroponics is a farming method without soil media that works by spraying water and a nutrient solution in the form of a mist on plant roots. The use of the aeroponic method itself requires monitoring and controlling air temperature, air humidity, water temperature, and nutrient levels. Incorrect settings can cause plants to experience drought, root rot, and a lack of nutritional elements, which can cause plant death. Therefore, we need a system that can monitor and control air temperature, air humidity, water temperature, and nutrient content. This research builds an Internet of Things-based system that can assist in providing information regarding the values of air temperature, air humidity, water temperature, and nutrient content displayed on the website application. The system can also perform manual and automatic control functions. In the test results, the sensor value reading system has an accuracy of 98.56% for air temperature, 96.89% for accuracy of air humidity readings, 99.64% for accuracy of water temperature readings, 97.02% for accuracy of nutrient solution readings, and 99.86% for accuracy of water level readings. The test results from observing potato plants for 21 days showed an increase in growth in the highest plant height with an average of 4.36 cm and the lowest plant height growth with an average of 0.96 cm.
