Abstract

In this modern era a motorcycle is very common means of transportation to use. With the increasing population of motorcycle users, accidents caused by motorbikes cannot be avoided. In general, accidents cannot be predicted when and where accidents occur. By using an accident notification system on a motorcycle, it will be easier to find out the location of the accident. So that the device does not consume excessive power on a motorcycle battery, it must have a low power mechanism to be able to save power. Low power and state machine mechanisms can be implemented in a prototype system that serves to inform that an accident has occurred by sending a short message containing the location of the accident. In testing the accuracy and functional levels of several components obtained results that are as expected. The MPU6050 sensor has an accuracy of 84.43%, the NEO6M module has an accuracy of 99.99% and the functional module SIM800L can send short messages properly. In testing the low power mechanism can reduce the power consumed by 22.2 mA or 18.8%. The device consumes power of 117.7 mA without using a low power mechanism and consumes power of 95.5 using the low power mechanism.

Abstract

Electricity is one of the necessities of human life. One of those that provide electricity services in Indonesia is a state-owned company, namely PLN. PLN itself has 2 categories of electricity customers, namely, prepaid and postpaid. Postpaid customers make bill payments according to the energy used for a period of 1 month. However, in reality in the field, according to the head of the daily management of YLKI (Indonesian Consumers Foundation), Tulus Abadi, PLN officials frequently record errors for postpaid customer electricity meters. The problem is that PLN is still monitoring customers manually for postpaid electricity. To overcome this, it is necessary to establish a kwh meter monitoring system for PLN customers. This monitoring system will send KWH usage data using the LoRa communication protocol which will then be sent through the gateway, then the data will be forwarded to the broker using the MQTT protocol and the data will be subscribed to by the client so that the data can be monitored regularly. In the research conducted, the author of this monitoring system has an average percentage of error data kwh of 0% and a wattage of 0.6% compared to other sensors KWE-PM01. For sending data from the sensor node to the client it can run well. At a distance of 100 meters to 300 meters, sending from the sensor node to the gateway is the best delivery in this study. Because the successful rate for testing single and multiple nodes at this distance, the packet can be received 100% by the gateway.
