Abstract

A line follower robot is a robot that works along a line. This robot is a very simple type of robot, so it is often used as training material for students who are new to robots. One of the indicators for assessing the performance of a line follower robot is the travel time achieved by the line follower robot in covering various trajectories correctly. The average speed of the robot at 90% and 75% PWM settings is almost the same with a value of around 41 cm/second, while at 50% PWM settings it is much reduced to 35.63 cm/second. At the 90% PWM setting, it can be seen that the path length ratio is 4.32: 2.06: 1, while the travel time ratio is 4.44: 2.66: 1. At the 75% PWM setting, it can be seen that the path length ratio is 4.32: 2.06 : 1. while the travel time ratio is 4.38 : 2.41 : 1. At 50% PWM setting, it can be seen that the path length ratio is 4.32 : 2.06 : 1. while the travel time ratio is 4.09 : 2.09 : 1

Abstract

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.

Abstract

Sasambo batik is a traditional batik from the West Nusa Tenggara province. Sasambo itself is an abbreviation of three tribes, namely the Sasak (sa) in the Lombok Islands, the Samawa (sam), and the Mbojo (bo) tribes in Sumbawa Island. Classification of batik motifs can use image processing technology, one of which is the Convolution Neural Network (CNN) algorithm. Before entering the classification process, the batik image first undergoes image resizing. After that, proceed with the operation of the convolution, pooling, and fully connected layers. The sample image of Lombok songket motifs and Sasambo batik consists of 20 songket fabric data with the same motif and color and 14 songket data with the same motif but different colors. In addition, there are 10 data points on songket fabrics with other motifs and colors. In addition, there are 5 data points on Sasambo batik fabrics with the same motif and color and 5 data points on Sasambo batik fabrics with the same motif but different colors. The training data rotates the image by 150 as many as 20 photos. Testing with motifs with the same color shows that the system's success rate is 83.85%. The highest average recognition for Sasambo batik cloth is in testing motifs with the same color for data in the database at 93.66%. The CNN modeling classification results indicate that the Sasambo batik cloth can be a reference for developing songket categorization using a website platform or the Android system.

Abstract

Advances in information technology have driven the use of digital media as a more effective means of conveying information in educational settings. However, SDIT Saad Bin Abi Waqqash does not yet have a digital information system capable of delivering information to the school community quickly and dynamically. This community service project aims to design and implement a digital information board system with a running-text display suitable for the school environment. The method used is an action research approach, which includes the identification, planning, implementation, and evaluation stages. The planning process involves determining the installation location based on the building’s layout and designing an LED dot-matrix system. The implementation results show that the running text system operates effectively, displays information in real time, and provides optimal visibility from various areas of the school. Additionally, the developed system is easy for users to operate via a smartphone-based application. Thus, the use of running text as a digital medium for information dissemination can enhance its effectiveness and support the use of technology in the school environment.
