Abstract

Network device monitoring has problems such as connectivity loss between routers. Network technicians are required to monitor all network devices at all times. This article aims to discuss the results of the network device monitoring system in Building A FPTK UPI using Grafana integrated with Telegram as an effort to monitor and repair problematic network devices. The method used is simulation using network software that is adjusted to actual conditions. Grafana and Prometheus are used in creating a device monitoring system. Prometheus works to retrieve data from the SNMP (Simple Network Management Protocol) and process the data using an exporter. Grafana can create visualizations on the network device monitoring system from the data that has been processed. This study uses a simulation method on PNETLab and VMware software. Based on the results obtained, the Grafana dashboard display can display the traffic interface on the router. The dashboard displayed is when ether 2 connected to the north 2nd floor router experiences interference which causes the north 2nd floor router to not get internet network access so that a warning appears in the form of a notification message R_LT2_UTARA | Down from DSTIbot via Telegram. The repair effort for the problem was carried out by connecting ether 3 from the middle 1st floor router to the north 2nd floor router so that the north 2nd floor router still gets internet network access. The repair displays the message notification R_LT2_UTARA | Up from DSTIbot via Telegram.

Abstract

Electrical energy has become a basic necessity today. As the population increases, the amount of electricity demand is also increasing. Therefore, many innovations are needed to meet these needs. One of the innovations in energy harvesting systems is the use of piezoelectricity. This research aims to create a piezoelectric-based running track prototype to produce environmentally friendly electrical energy. The arrangement of piezoelectric sensors used in this research is a parallel circuit. The research method used is the Research and Development method. The test results on the physical activities of walking, running, and jumping show that the prototype system that has been made has worked well and produces a fairly stable electric voltage even though it is still in a small amount. the difference in activity and body weight that presses the prototype produces different electric voltages. For walking activity, the prototype is able to produce a maximum voltage output of 0.83V, running activity has a maximum output of 5.83V and the maximum voltage output of jumping activity is 7.88V. The use of energy is done by storing the energy obtained from the piezoelectric in the battery, which can later be monitored directly by the voltage sensor, bluetooth module, HC-05, and RTC module the data will be sent to the cell phone so that the piezoelectric output voltage can be recorded and monitored. The electrical energy output generated by the piezoelectric is able to charge the battery and switch on the LED light at 2.5 V.

Abstract

The need for simplicity in various activities encourages further technological development. One of them is a system to turn lights on and off with just a hand gesture. This hand gesture-based One-phase smart switch uses OpenCV, Arduino Nano, relays, and webcam cameras to recognize hand gestures. Static finger movements are used as buttons to turn on the lights. The results show that the algorithm used has high reliability with a precision score of 0.90, sensitivity of 0.90, accuracy of 0.96, and F1-score of 0.90. The accuracy of the system is affected by light intensity, distance, and hand tilt angle. At a light intensity of 70 LUX, the accuracy reaches 100%, while at 40 LUX the accuracy ranges from 98-99%. A distance of 30-60 cm gave the best accuracy of 100%, but decreased at longer distances. A hand tilt of 0° gives 100% accuracy, while at an angle of 60° the accuracy drops significantly, especially for the fifth finger with 64% accuracy. The average response time of the light to finger movement is 0.133 seconds. This device can recognize a variety of finger patterns well, thus meeting the desired needs.

Abstract

Sistem monitoring dan otomasi rumah jamur sangat diperlukan untuk budidaya jamur. Sistem ini membutuhkan suatu protokol yang dapat membantu pengiriman data yang handal agar keadaan lingkungan dapat terpantau dengan baik. Ketika jaringan dengan protokol TCP terganggu, monitoring kondisi kumbung jamur akan terhambat, berdampak pada pertumbuhan jamur yang tidak optimal. Penelitian ini bertujuan untuk mengimplementasikan protokol TCP dan UDP pada sistem monitoring dan otomasi rumah jamur menggunakan iot berorientasi Wireless Sensor Network (WSN). Sistem menggunakan dua jenis mirkokontroller Wemos D1 mini ESP8266 dan Arduino UNO. Untuk satu mikrokontroller akan ditempatkan di dalam kumbung jamur untuk mengambil data lingkungan kumbung jamur yang diberi nama node sensor dan satu lagi berada di luar kumbung jamur yang diberi nama gateway. Node sensor akan dipasang sensor suhu dan kelembaban udara, soil moisture sensor, sensor intensitas cahaya, dan sensor CO2. Proses pengiriman data dari node sensor ke gateway menggunakan protokol UDP dan dari gateway ke server menggunakan protokol TCP. Hasil yang diperoleh adalah sistem monitoring dan otomasi rumah jamur dapat berjalan dengan baik. Hasil perbandingan menunjukkan bahwa protokol UDP memiliki delay yang lebih kecil dibanding TCP yaitu dengan perbedaan 96.153 ms. Tetapi untuk parameter throughput protokol TCP memiliki nilai lebih besar dibanding protokol UDP. Untuk koneksi dari node ke gateway lebih baik menggunakan protokol UDP karena pengiriman yang cepat dan data yang sedikit dikirim sehingga lebih efektif. Tetapi pada gateway ke server lebih baik menggunakan protokol TCP, karena data yang dikirimkan bisa banyak dan data harus terjamin sampai pada server. The utilization of mushroom house monitoring and automation systems is crucial in the context of mushroom growing. The successful monitoring of environmental conditions necessitates the implementation of a protocol that facilitates the transmission of dependable data. In the event of a disruption in the network utilizing the Transmission Control Protocol (TCP), the ability to monitor the status of the mushroom house would be impeded, thus leading to suboptimal mushroom growth. The objective of this project is to apply the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) in a monitoring and automation system for mushroom houses. This will be achieved by utilizing a Wireless Sensor Network (WSN) that is specifically designed for Internet of Things (IoT) applications. The system employs two distinct microcontrollers, namely the Wemos D1 small ESP8266 and the Arduino UNO. A sensor node, referred to as the microcontroller, will be positioned within the mushroom home to collect environmental data. Additionally, a gateway microcontroller will be situated outside the mushroom house. The sensor nodes will be equipped with temperature and humidity sensors, soil moisture sensors, light intensity sensors, and CO2 sensors. The transmission of data from the sensor node to the gateway is facilitated by the User Datagram Protocol (UDP), while the transmission from the gateway to the server is facilitated by the Transmission Control Protocol (TCP). The findings indicate that the mushroom house monitoring and automation system operates effectively. The comparison results show that the UDP protocol has a smaller delay than TCP, with a difference of 96.153 ms. In contrast, the throughput parameter of the TCP protocol has a higher value compared to that of the UDP protocol. When establishing connections between nodes and gateways, it is advisable to utilize the User Datagram Protocol (UDP) due to its advantages in terms of expedited delivery and efficient data transmission, as it involves less data overhead. However, it is advisable to utilize the TCP protocol for the gateway to the server, as it ensures reliable delivery of large volumes of data to the server.
