The public's need to get high-speed internet services that can be accessed anywhere is a current need. One of the internet network services that is often accessed by the public is video streaming. The emergence of cellular providers with various advantages, each of which is a challenge in choosing a reliable provider. To find out which telecommunications provider/organizer is good for use in an area, especially in the city of Mataram, throughput values were measured using the Wireshark application. The main goal is to find out the throughput value which is a comparison of the download and upload sides. The morning measurement results using provider A had an average value of 484.76 kbps, in the afternoon it was 493.97 kbps and in the evening 401.65 kbps. Meanwhile, measurements using provider B have an average value of 1187.13 kbps in the morning, 1280.04 kbps in the afternoon and 844.46 kbps in the evening. From the calculation results obtained, it was concluded that provider B was better than provider A.

Sistem Keamanan Sepeda Listrik Menggunakan Fingerprint

Zhera putri yulianingsih — Sat, 30 Mar 2024 14:18:00 +0000

Fingerprint sensor technology has been implemented in a security system for electric bicycles using Arduino IDE as the core of the system. The main components consist of a fingerprint sensor, relay, and buzzer. The fingerprint sensor is responsible for reading the enrolled fingerprint, while the relay serves as a switch to regulate the flow of electricity to the electric bicycle. This approach provides an innovative solution that enhances the security level of the electric bicycle by allowing users to only access the bicycle using an enrolled fingerprint. Thus, the system combines reliable security with user convenience. Based on this research, it was found that the security system using Arduino Uno ATMega328 microcontroller and fingerprint sensor works well, allowing only the registered owner to access the electric bicycle. This proves that the use of biometric technology such as fingerprint sensors can be an effective solution to improve the security of electric bicycles.

Pests are one of the scourges that often lead to crop failure. Some challenges faced by farmers in growing rice include rat and bird pests. Therefore, this study designs a system to repel pests. It uses an ESP32 microcontroller connected to a PIR (Passive Infrared Sensor) to detect pest movement. When pests are detected, the system will activate several pest repelling components, including a buzzer to produce a sound that scares rats, an electrified wire fence to repel rats, and a servo that moves to repel birds, where the servo will also be active if an anemometer detects winds of 3000-4000 m/s. The tool is monitored in real time using Arduino Cloud IoT software connected to the internet. The purpose of monitoring is to determine the success of the tool in repelling pests. This prototype system has been tested on a small scale, with separate tests for rat and bird pests. The PIR sensor successfully detected pest movement within a range of up to 4 meters. From the testing on 8 birds, 5 were successfully repelled by the servo movement. For rats, the buzzer effectively disturbed rats up to a distance of 40 cm, and with the support of a high voltage module kit, rats were successfully repelled up to a distance of 80 cm. Then the pests can be monitored in real time using Arduino Cloud IoT software. Then field testing was conducted on the prototype for 6 days, where the development of the success rate of the tool was observed from 3 days without repelling and 3 days of repelling to find out the difference in the number of pests repelled. The results of the testing showed a decrease in rat and bird pests, with a decrease in the number of rats and birds detected.

Analisis pengaruh Co-firing biomasa terhadap kinerja peralatan boiler CFB pada PLTU Jeranjang OMU unit 3

Suanggoro Legowo, I Ketut Wiryajati — Sat, 30 Mar 2024 14:26:10 +0000

Dalam upaya untuk meningkatkan efisiensi dan mengurangi dampak lingkungan negatif, Indonesia telah mengambil langkah maju dalam menerapkan Energi Baru dan Terbarukan (EBT) sebagai bagian dari matriks energi nasional, salah satu langkah tersebut adalah dengan melakukan co-firing biomassa pada pembangkit listrik tenaga uap (PLTU). Penerapan co-firing tersebut pasti akan berdampak secara langsung maupun tidak langsung pada peralatan boiler. Terdapat tiga pendekatan co-firing yaitu direct, indirect dan paralel, umumnya pendekatan yang sering digunakan adalah direct co-firing karena lebih ekonomis.Dari perbandingan yang dilakukan didapatkan hasil bahwa penerapan co-firing tidak mempengaruhi kinerja peralatan boiler, bahkan efisiensi PLTU semakin meningkat dani polutan yang dihasilkan oleh PLTU berkurang.
