Abstract

Markas Komando Brimob uses optical fiber as a transmission media in the design of the Sistem Informasi dan Administrasi Brimob (SIAB) communication network. Optical fiber has a large transmission capacity, therefore fiber optic networks are implemented on network of SIAB. This facility includes withdrawal of fiber optic cable from Mako Brimob to seven points, namely Pool Mako, Mako Gegana, Pool Bengkel Gegana, Detasemen Gegana, Pool KBR, Pool Pelopor, and Danpas Pelopor. The design of the SIAB network is adjusted to the needs of the Mako Brimob such as: 10-10 of BER, 100 Mbps of data speed, and 1310 nm of wavelength. The optical equipment used were single fiber optic tube loosen mode, PIN photodiode light detector, optical laser diode, and SC connector. From the power link analysis, the maximum distance without using an optical amplifier was 491.9 km. Then, the maximum speed was 896 Mbps measured using rise time budget. Keywords: Power link budget, Rise time budget

Abstract

ABSTRACT Trans Semarang buses as transportation used by residents the city of Semarang often experience delays at one corridor stop so that passenger waiting times are quite long, so monitoring is needed on each bus. LoRa with long-distance communication capabilities without an internet signal with low power over a wide area, so it can be used to monitor the position and speed of the Trans Semarang bus for efficient passenger waiting time. The tool used to monitor Trans Semarang bus consists of a transmitter section as a data sender and a receiver as a data receiver with 915 MHz LoRa communication media and there is a buzzer as a bus speed warning and an emergency button when the bus has problems on the road. The test results from this study are the device can send and receive data with the furthest distance of 2200 meters with a maximum speed that can be measured is 46 km/hour, then it can give speed limit warnings and bus emergency warnings. Keywords : LoRa 915 MHz, Trans Semarang Bus, Distance, Speed
