Object Following Design for a Mobile Robot using Neural Network

Deciding the best method for robot navigation is the most important tasks in mobile robot design, defined as the robot's ability to reach the target or/and move around its environment safely using the installed sensors and/or predefined map. To achieve this objective, wall or object detection can be considered. It is common to derive kinematics and dynamics to design the controls system of the robot, however by giving intelligence system to the robot, the control system will provide better performance for robot navigation. One of the most applied artificial intelligence is neural networks, a good approach for sensors of mobile robot system that is difficult to be modeled with an accurate mathematical equations. Mostly discussed basic navigation of a mobile robot is wall following. Wall following robot has been used for many application not only in industrial as a transport robot but also in domestic or hospital. Two behaviors are designed in this paper, wall following and object following. Object following behavior is developed from wall following by utilizing data from 4 installed distance sensors. The leader robot as the target for the follower robot, therefore the follower robot will keep on trying reaching for the leader in a safe distance. The novelty of this research is in the sense of the simplicity of proposed method. The feasibility of our proposed design is proven by simulation where all the results shows the effectiveness of the proposed method

EFEKTIVITAS PELATIHAN PEMANFAATAN POWER POINT MELALUI METODE ASISTENSI UNTUK MENINGKATKAN KOMPETENSI GURU DI SMPN 37 PALEMBANG

This community service was inspired by teachers' lack of capacity at SMP N 37 Palembang to use the PowerPoint application as a teaching aid in the classroom. A training program for the use of PowerPoint applications is therefore required to provide teacher training to optimize the PowerPoint application's role as an interactive learning tool that can be used for individual learning and indirectly increase teacher competence scores. To enhance this program's effectiveness, the Instructors from the Electrical Engineering Department of Politeknik Negeri Sriwijaya use the Assistance Approach as a way of distributing materials from the Community Service Team (Instructors) to the Teacher (Participants) to improve the comprehension of the materials provided. Observation and evaluation results show (a) Participants applied the assistance method with 85.5 points, excluding the assistance method with 71.5 points. (b) The pre-test results averaged 70 points, and the post-test results averaged 90 points

The impact of Nodes Distance on Wireless Energy Transfer System

Wireless energy transfer (WET) reemerges as the method for transmitting electric power without the necessity to deal with cable losses and an aesthetically pleasing environment. The problem with WET is how to maintain magnetic induction as the distance gets further. This paper investigates the impact of nodes distance on the WET system. The experimental results show that the most effective distance among transmitter, nodes, and receiver are 4 cm. The measurement is taken with and without load. The without load application give that for node 1; the results are 6 V, 110 mA, and 2.85 mT for voltage, current, and magnetic flux, respectively. At the application of 2 nodes, the voltage is 6.8 V, the current is 0.124 mA, and the magnetic flux is 3.83 mT, and at three nodes installation, it is 7 V, 134 mA, and 3.83 mT. During the application of 3-Watt and 5-Watt lamp, at 4 cm distance, the power received is 1.66 W and 3.66 W at 3-Watt and 5-Watt lamp for one node, 1.84 W, and 3.84 for two nodes, and 1.93 W and 3.93 for three nodes. The experimental results show that the transmitted signal can be prolonged by installing nodes. Even though this study shows that 4 cm is the most effective, it is possible to increase up to 20 cm to power a 3-Watt lamp and 5-Watt lamp

LITERASI MEDIA ISLAMI ANAK MENGGUNAKAN METODE “SATU ANAK SATU BUKU”

Literacy for early education students can be defined as the ability of reading and writing. This capability will increase if (1) facilities and (2) infrastructure are easily accessed, and (3) supported by the environment. The observation shows that those three factors are not available for children learning Al-Quran and Islam in Al-Ikhlas Masjid, especially Islamic media literacy. The community service was conducted in Al-Ikhlas Masjid to increase Islamic literacy for children using the method of "One Child One Book." Books and short version of Al-Quran were donated to encourage the children to enjoy reading and writing. This method was successful in increasing children's interest in reading shown by the enthusiasm of 14 children who came to participate in the activities.The Al-Ikhlas Masjid became crowded because the children came almost every evening to read and borrow books. Everyone was happy to read the books provided by the team. Therefore, the community service was considered successful in increasing Islamic literacy proven by an excellent reception from parents and children studying at Al-Ikhlas Masjid, and they are expecting further activities

PELATIHAN PENULISAN KARYA TULIS ILMIAH KELOMPOK IPA DAN IPS SMAN 6 PALEMBANG

Scientific writing is a scientific means of communication that uses systematics appropriate to the scientific community through an accepted writing system where scientific features of a scientific paper are empirical and objective to be regarded. However, not all students have the capacity to do so, hence the need for science writing instruction for students. The activities of the Community Service Team, consisting of 3 lecturers and 3 students of the Electrical Engineering Department of Politeknik Negeri Sriwijaya, are to enrich students to write appropriate scientific papers in compliance with the guidelines for writing. The presentation/discussion, assessment, and mentoring of this activity have been carried out in conjunction with the stated targets. Students' high motivation is shown by the assistance and assessment of the titles and writings offered by the Community Service Team

Aplikasi Rangkaian Pengali Tegangan Walton Cockcroft Dan Sensor Af-30 Pada Penjernih Udara Ruangan Otomatis

Air is very important for all the living being in this planet, therefore good quality of air has to be maintained. The air quality in our office environment is much decreasing nowadays, due to human behaviour and life style, such as smoking and in return reduces our health. This reasearch proposes to design an air purifer to increase air quality inside a room. The propose air purifier applies Walton Cockcroft voltage multiflier with voltage output 4000-5000 Vdc to separate carbonmonoxide (CO) from oxigen. This device will work as soon as smoke sensor AF-30 detects carbonmonoxide in the air. This carbonmonoxide detection will result analog signal as the input to the programmed microcontroller ATMega 8535. The output signal of microcontroller ATMega 8535 will activate relay switch circuit and in the end will activate DC Motor fan, voltage multiplier circuit and exhaust fan. The voltage multiplier circuit output is 4420 volt DC at the 13th stage, this high voltage will ionize carbonmonoxide (negatif ion) from oxigen (positif ion). After positif and negative ion get separated, negatif ion would be outed by DC fan to the purifier element, the negatif ion would be the residue and stayed inside the purifier. It is hoped that this device would help in increasing air quality in side office room

The Concept of Automatic Transport System Utilizing Weight Sensor

The current pandemic situation insists that people find a way to create a physical distance, limiting the number of people in a closed room. The human need for commuting has led to the idea of an automatic transport system that can transport people and goods without the assistance of a driver. This idea can lead to a new "normal" and reduced cost of manufacturing in the industry. The paper discussed the concept of an automatic transport system using a weight sensor. An automatic vehicle is designed to transport loads of different packages and be allocated automatically based on the weight of the package. The system is designed to be as simple as possible to increase the scope for implementation
