Perkembangan teknologi modern dapat memudahkan pekerjaan manusia. Salah satunya teknologi robot yang banyak diaplikasikan pada bidang industri, medis dan alat-alat rumah. Robot ini diprogram berdasarkan ide logika dan meniru prilaku makhluk hidup, sehingga robot dapat bergerak sesuai keinginan pengguna. Pembelajaran robot umumnya ada pada Jurusan Teknik di Perguruan Tinggi. Untuk pemula perlu dikenalkan teknologi robot dan pemrogramnya kepada Siswa SMK dengan tujuan menambah pengetahuan dan meningkatkan keterampilan. Kegiatan pelatihan ini ditujukan kepada Siswa SMK Negeri 1 Indralaya Selatan sebanyak 20 orang siswa. Adapun metode pelaksanaan kegiatan ini yaitu melakukan pretest, memberikan pengenalan tentang konsep dan ilmu robotik, memotivasi siswa untuk aktif dalam kegiatan dan memprogram robot (learning by doing), dan melakukan posttest. Selama pelaksanaan kegiatan berlangsung siswa berperan aktif dan tertarik dalam mencoba dan bertanya kepada instruktur. Adapun hasil pelaksanaan kegiatan pelatihan ini yaitu pada saat dilakukan pretest banyak siswa yang belum paham tentang robot, namun setelah diberikan pemahaman dan cara memprogram robot sederhana khususnya “robot menghindar halangan” siswa dapat mengenal dan mengerti tentang logika program robot. Hal ini dapat ditunjukkan dari hasil posttest dengan tingkat keberhasilan siswa sebesar 85%.

Gas leakage in industrial areas will have negative impacts such as air pollution, loss, or even disaster. The occurrence of leakage can be caused by corrosion or from the valve crack in the pipe, and so forth. Therefore, it is necessary to have a system that can monitor the state of the gas pipeline so the possibility of leakage can be known earlier. This research has developed application of robot manipulator 4 DOF integrated with gas sensor that is MQ4 which placed at end of robot arm. The method used to determine the motion of the robot is trajectory planning in the form of cubic trajectory, where in this method the robot movement route will adjust the pattern of pipelines in cartesian coordinates. To determine the possibility of a leak of butane gas, observed the output signal from the gas sensor. If it exceeds 3.5 volts then the coordinates passed by the end-effector may leak. The experimental results show that robot manipulators with cubic trajectory planning are able to track paths according to the shape of pipes, and gas leaks can be detected by gas sensors.

Humanoid robots are designed to mimic human structures and utilize cameras to process visual input to identify surrounding objects. However, previous studies have focused solely on object detection, overlooking both the complexities of real-world implementation and the significance of calculating the distance between objects and the robot. This study proposes a system that employs the you only look once (YOLO) algorithm to detect various objects in the proximity of a robot. Using a dataset of primary data collected in a laboratory, the detected objects are from 12 classes, including humans, chairs, tables, cabinets, computers, books, doors, bottles, eggs, learning modules, cups, and hands, with each class comprising 1500 data points. Two YOLO architectures, namely tiny YOLOv3 and tiny YOLOv4, are assessed for their performance in object detection, with the tiny YOLOv4 demonstrating a superior accuracy of 82.99% compared to tiny YOLOv3. Evaluation under simulated conditions yields an accuracy of 74.16%, while in real-time scenarios, accuracies are 61.66% under bright conditions and 38.33% under dim conditions, affirming tiny YOLOv4’s efficacy. Moreover, this study reveals an average error distance of 31% between an object and the robot in real-time conditions. The developed system enhances human–robot interaction capabilities via data transmission.

Tanjung Pinang II Village is one of the districts in Tanjung Batu, Ogan Ilir Regency, South Sumatra, which is currently developing its potential to become a tourist village through an agro-park. However, the process of transforming the village into a tourism and educational area for the community has not yet implemented technology. Therefore, in this community service, a smart greenhouse was developed and implemented in Tanjung Pinang II Village. The methods used in this community service included situational analysis, greenhouse construction, counseling and training, as well as evaluation, analysis, and conclusion. The constructed greenhouse is equipped with temperature and humidity sensors to measure the conditions inside the room. The greenhouse is built with a steel frame and uses UV plastic for its roof and walls. The results of the community service showed that the village residents and the community benefited from the greenhouse in the process of developing Tanjung Pinang II Village as an ecotourism area.

Biomedical technology has now been widely adopted as a means of monitoring the human body in real-time. For example, to detect eye movement. In the medical world, eye movement can be used to determine the type of disease. With the application of human-machine interface (HMI) technology, eyeball movement can be developed in the robotics industry as robot navigation. For example, by moving the eyeball left and right, the robot can interpret the eye signal to move left and right. The interaction between the eyeball movement and the robot is of particular concern in this study. This study aimed to design a measuring instrument for eye movement detection using Electrooculography (EOG) techniques to move a wheeled robot. The EOG measuring instrument consisting of an instrument differential amplifier, a low pass filter, and a high pass filter has been applied in this research. The signal generator technique on EOG is carried out by placing electrodes on three sides of the face, namely forehead (G), left horizontal (H-), right horizontal (H +). The experimental results showed a significant difference between the left and right eye movement amplitude signals. This amplitude is used to classify the movement of the robot wheel towards the left and right. The process of sending robot signals and EOG measuring instruments uses Bluetooth HC-05 serial communication. Based on the research results, it is proven that the robot manages to move left and right according to the eyeball movement.
