Abstract

In the contest of Indonesian wheeled robot football or KRSBI wheeled robot which competes with wheeled football robots, there is a referee who controls the course of the match, the referee box. For referee box to provide commands that can set the course of the robot, a base station is required that serves to receive data from the referee box and translated and then sent it to the robot. The use of TCP socket programming is quite successful whereby 17 attempts to send commands from referee box can be accepted all by base station with a success rate of 100%. The use of robot operating system (ROS) to pass data in the form of coordinate points and commands for robots chasing balls or stops was also successfully carried out where from 17 attempts the delivery of orders, it can reach 100% success rate. After that, the measurement of distance analysis against quality of service (QoS) with 3 different distances, and obtained the following results, at a distance of 3 meters obtained an average delay of 44.41 ms, throughput of 767.29 kbps and no missing package, at a distance of 8 meters obtained an average delay of 7.22 ms, an average throughput of 1065.17 kbps and no missing packages, lastly at a distance of 15 meters obtained an average delay of 103.99 ms, an average throughput of 835.51 kbps and there was a missing package of 6.9% on 1 order so that the average lost package was obtained by 0.405%.

Abstract

An Islamic educational facility called a pesantren houses students, or santri, in dormitories. One of the biggest Islamic boarding schools in Jombang is called Darul 'Ulum. Students are expected to participate in early recitation activities, are forbidden from smoking, are forbidden from visiting the student rooms without the coach's permission, and are forbidden from entering the guest rooms. This research used a case study of a high school dormitory as an example. For proper monitoring of student breaches, a high number of students demand more efficient supervision. Based on these issues, a monitoring system is required that may alert the hostel supervisor to infractions in real-time, allowing them to take fast action against violators and impose sanctions in line with the seriousness of the offenses. This study uses an android application monitoring of students. According to the results of testing violations of students who smoke in the room using the MQ-2 sensor with 10 test trials, a 100% success rate is obtained in detecting cigarette smoke, and testing violations of students who are still in the room at the time of the early Koran reading with using a PIR sensor with 10 test trials, the success rate was 100% in detecting the presence of students. Both the RFID sensor test and the fingerprint sensor test resulted in delays of 1.59 seconds and 3.01 seconds, respectively, with 100% success rates.

Abstract

The value of signal attenuation by the resulting weather changes may differ at any time. The collection of signal power data with different times, weather, humidity, rainfall, and temperatures using the drive test method in Malang area will be processed using machine learning methods and backpropagation algorithms. The process is carried out using Matlab software. In this study, data collection is carried out on four BTS ranges. In addition to these data, it is also necessary to calculate the value of signal attenuation by weather changes in order to find out whether the weather category is good or bad for telecommunications activities. When the weather is sunny and cloudy it has an RSSI range value of -85 dBm to -75 dBm, while in cloudy and rainy weather it has an RSSI range of -104,2 dBm to -87 dBm. Data from the results of the drive test measurements obtained the signal attenuation value by the largest weather change of 40.49718 dB and the largest rainfall of 681.8 mm / hour. Based on the test data, the signal attenuation value when the weather is sunny and cloudy is worth 0.096164 dB to 8.61604 dB, and in cloudy and rainy weather it has a greater attenuation value, from 12.3466 dB to 21.0098 dB. Using the backpropagation algorithm, the accuracy rate in this prediction reaches 99.7 %.

Abstract

A key is a tool made of metal to open or fasten a door or object that has a lock by inserting it into the hole in the main key. The lock itself is usually used on doors, suitcases, or other objects that require security. The lock on the suitcase itself still has a slight variation and there are still weaknesses, for example the code lock if you forget it cannot be opened, then the padlock and slot lock if the key is lost cannot be opened and can still be broken into by lockpick. The type of research carried out is included in the type of research and development (Research and Development). So, from these problems, a system will be designed and built that can monitor and maximize security automatically so that user's goods are protected from crime or theft by utilizing Near Field Communication (NFC), Global Positioning System (GPS), Magnetic Sensors and Microcontrollers. This system is made portable, so that it can be used in various goods with certain conditions, for example suitcases. The results of this research are portable lock tools, and applications that can integrate lock tools in real time. From the test results obtained accuracy on the gps key, and the security system can run according to the program.
