Abstract

A remote weather station requires solar power system (PLTS), hence making power consumption calculation is very essential. PLTS analysis is applied to an ESP32-based weather station with low-power sensors to reduce costs. The process starts with setting up the station and PLTS without prior analysis, followed by a literature review, data collection of current and voltage from the SCC, conducting an analysis, and finally determining components recommendations. Calculations determine the need for a 12V, 4.375 Ah battery, 14.255 Wp solar panel, and a SCC with 0.46 A battery current and 0.306 A load current. Adjusted to market availability, a VRLA 12V/6Ah battery, 20 Wp solar panel, and 5A SCC module can replace the previously used 12V/7Ah battery, 50 Wp solar panel, and 10A SCC.

Abstract

This research aims to develop a remote control system for waste collection machines using Arduino Nano and LoRa communication modules. The background of this research is the need for an effective remote control system to manage waste collection machines automatically. This system is designed to optimize the machine control process through stable wireless communication. The research process begins with system design, including block diagrams and flowcharts for remote control transmitters and receivers. The transmitter uses an Arduino Nano to read input from the button and send data via the LoRa module. The receiver receives signals from the transmitter, then controls the motor using the L298N motor driver module based on the data received. The research results show that the system can control the motorbike accurately according to the signals received, including forward, backward, right turn and left turn movements. The system is also capable of handling button combinations for more complex motor control. The use of Fritzing and Visual Studio Code in the design and programming process makes system implementation and testing easier. This research provides a practical solution for remotely controlling waste collection machines with LoRa communication.

Abstract

The need for high-speed internet continues to increase with technological developments. Fiber to the Building (FTTB) is a solution for providing fast internet access to commercial and residential buildings. However, the main challenge in maintaining network quality is attenuation in fiber optic cables, especially at connections. This research aims to analyze the effect of pigtail cable length and connection quality on the total attenuation from the Optical Distribution Frame (ODF) to the Optical Distribution Cabinet (ODC) in the FTTB network, both before and after activation. The research method uses pigtail cables of varying lengths, from 30 cm to 150 cm. Some connections are carried out according to Standard Operating Procedures (SOP), while others are not, to measure the effect of connection quality on attenuation. Measurements were carried out using an Optical Power Meter (OPM) and Passive Optical Network (PON) technology with an SFP of 8 dB. The research results show that connections that comply with the SOP produce lower attenuation, namely 7.16 dB on a 150 cm cable, 7.09 dB on a 120 cm cable, and 6.99 dB on a 100 cm cable. On the other hand, connections that do not comply with the SOP produce higher attenuation, namely 8.15 dB on an 80 cm cable, 8.08 dB on a 50 cm cable, and 8.02 dB on a 30 cm cable. This research contributes to the optimization of FTTB network installations.
