Abstract

Computer networks are very important for people in the current era of modern globalization to access their daily needs. A good computer network is certainly needed to speed up community activities. Sub-netting is one of the things that can be done to optimize IP management on a computer network. This research on the application of the subnetting method on a computer network can be a reference in determining a better subnetting method for building a network. This research aims to analyze the influence of the two subnetting methods on a computer network, compare the network speeds obtained, and the application of the two subnetting methods on a computer network based on QoS parameters. The research results show that the analysis of both subnetting methods displays a very good QoS Index with the following details: FLSM: average throughput 50.792kbps, packet loss 0%, average delay 5.25ms, average jitter 5.37ms. VLSM: average throughput 77.843kbps, packet loss 0%, average delay 3.52ms, average jitter 3.58ms. In the FLSM method, all applied subnets have 101 remaining unused IPs and in VLSM, all applied subnets have 19 unused IPs remaining. This proves that networks designed using the VLSM subnetting method have more optimal network quality and more effective IP management.

Abstract

This community service was carried out in the Tambak Hamlet, Ngestiharjo Village, Kasihan, Bantul, Yogyakarta. Tambak Hamlet is a hamlet located in the Ngestiharjo Village, Bantul, which is on the outskirts of Yogyakarta. Therefore, the population in this area is quite dense, so that agricultural land becomes increasingly limited. Narrow land still exists in this area, which can be used for farming or planting horticultural crops. However, nowadays the weather is getting more and more erratic, so the time for planting is becoming more difficult. In Tambak Hamlet there is already an IoT-based green house for smart farming for horticultural crops, but it has not been managed, because it is still in the development stage. Based on this, the service team is trying to make a suggestion regarding the management of the green house, so that the results can be maximized and able to increase the economic value for the community. This service aims to develop agricultural digitalization through the Smart Farming Model, using Internet of Things (IoT) technology, to assist in crop monitoring, so that the growth and yield of horticultural crops is optimal. The purpose of this service is in line with the 3rd and 5th Main Performance Indicators (IKU) of Higher Education. The 3rd IKU, namely lecturers who carry out activities outside the campus, in this case the lecturer performs community service which is carried out in the Tambak Hamlet. The 5th IKU is the work of lecturers used by the community, namely in the form of ideas and thoughts in the development of smart farming. The expected outputs from this community service activity are services in the form of training and assistance for the management of green house smart farming, and publication in the form of scientific articles that will be published in national journals.

Abstract

The inefficiency and potential for operator error in manual height measurements limit data reliability in health and fitness monitoring. To address this, we developed an automated IoT-based system to compare the performance of HC-SR04 and HY-SRF05 ultrasonic sensors. The system architecture is built on a NodeMCU ESP8266 microcontroller, which sends measurement data to a cloud-based Firebase platform for real-time storage and historical analysis, all visualized on a dynamic ReactJS dashboard. The evaluation involved 30 human subjects with heights ranging from 100 to 200 cm. The analysis revealed a mean absolute error of 0.20 cm (0.131%) for HY-SRF05 and 0.233 cm (0.16%) for HC-SR04. Crucially, statistical testing found no significant difference in accuracy between the two sensors (T-test, p > 0.05). The study concludes that both low-cost sensors are highly capable and statistically equivalent for this application. The complete IoT system demonstrates a robust solution for deploying affordable, scalable, and accurate automated height measurement tools, offering a significant improvement over traditional methods.

Abstract

Penetration testing is a method used to identify security vulnerabilities in networks or computer systems. In this process, pentesters attempt to exploit security gaps by simulating potential attacks that could be carried out by an actual attacker. The goal of penetration testing is to evaluate the security of computer systems or networks. This multi-stage approach, which includes information gathering, exploitation, and post-exploitation, utilizes the MITRE ATT&CK framework. Tools are used to help identify and exploit security weaknesses, such as nmap, netdiscover, metasploit, SSH, and MySQL. This research can reduce the risk of data loss and operational disruptions, enhance pentesters' skills and awareness, and strengthen the security of computer systems and networks.

Abstract

Penelitian ini fokus pada dampak meningkatnya penggunaan internet secara massif, terutama dalam konteks kehabisan sumber daya IPv4 dan peralihan ke IPv6. Selain itu, penelitian juga menyoroti peran ketersediaan jaringan dan kemampuan dalam mengatasi kegagalan pada router dalam konteks manajemen perangkat dan kualitas layanan. Penelitian ini membandingkan performa HSRP dan GLBP dengan IPv6 menggunakan parameter QoS (Quality of Service), termasuk delay, throughput, downtime, dan packet loss. HSRP menunjukkan kinerja lebih baik daripada GLBP dalam kondisi default, dengan throughput HSRP lebih tinggi (0,128 Bps), packet loss yang lebih rendah (0%), dan delay yang lebih rendah (0,308 ms). Saat terjadi hardware failure, HSRP tetap unggul dalam throughput (perbedaan sekitar 0,695 Bps) namun memiliki packet loss lebih tinggi (0,55%) dan delay yang lebih tinggi (0,566 ms). Downtime yang dibutuhkan oleh HSRP juga lebih cepat (8,13 detik) dibandingkan dengan GLBP (8,6 detik), dengan selisih sekitar 0,47 detik.

One promising alternative is urban farming supported by the Internet of Things (IoT). This research aims to design and develop an IoT-based smart farming system for monitoring vegetable crops in urban areas with limited land availability. The system uses a NodeMCU ESP32 as the main controller, an SHT20 sensor to measure temperature and humidity, and a pH sensor to monitor the acidity of the nutrient solution. Sensor data are displayed in real time through an LCD and an Android-based application, and are also used to control an automatic fan to maintain optimal environmental conditions. The research method applied is an experimental approach comprising a literature review, system design, hardware and software implementation, and system testing. Based on the research results, the IoT-based smart farming system was successfully developed and can monitor plant environmental conditions and nutrient solutions in real time via an Android application, with data stored in a database and displayed appropriately. The test results indicate that the system helps users manage vegetable cultivation more efficiently. This system is expected to provide an effective, efficient, and sustainable smart farming solution for urban areas with limited land availability.

Abstract

Population growth continues to drive food demand, while agricultural land becomes increasingly scarce due to urbanization and land conversion. This condition demands agricultural innovations that can increase productivity sustainably in limited land. One emerging solution is the hydroponic system, but managing key parameters such as water temperature, water level, and nutrient content (TDS) is often still done manually, which risks reducing crop quality. This study aims to design and implement an Internet of Things (IoT)-based hydroponic system capable of real-time and remote monitoring. The research method used is an experimental method, including literature review, needs analysis, system design, hardware and software installation, and system testing. The system was developed using an ESP32 microcontroller with a DS18B20 temperature sensor, a JSN SR04T ultrasonic sensor, and a TDS sensor, along with an Android application as the monitoring interface. The design results show that the system can monitor hydroponic conditions in real time, powered by solar panels. This system is expected to improve the efficiency of nutrient management and support the implementation of smart agriculture in limited land.

Abstract

The development of urban agriculture faces challenges related to limited land availability, water scarcity, and inefficient plant management. These conditions encourage the adoption of smart agricultural technologies that operate automatically and efficiently. This study aims to develop an IoT-based smart mini greenhouse prototype suitable for urban environments with limited space. The research method used is an experimental approach focusing on system design and implementation. The system employs an ESP32 microcontroller as the main control unit and is equipped with pH, Electrical Conductivity, and water temperature sensors to monitor the quality of hydroponic nutrient solutions. Sensor data are automatically processed to control circulation pumps and nutrient correction pumps via relay modules, and the data are transmitted to a web-based monitoring system in real time. The test results show that the system can monitor water quality parameters stably and automatically perform irrigation and nutrient correction according to predefined threshold values. The implementation of this system improves the efficiency of water and nutrient management and reduces reliance on manual monitoring. These results indicate that the IoT-based smart mini greenhouse has the potential to serve as a practical and sustainable solution for supporting urban farming in areas with limited land.
