<![CDATA[Sistem kendali attitude hold pada multirotor adalah sebuah sistem kendali penjaga sikap untuk mempertahankan sikap stabil saat terbang. Sistem attitude hold pada penelitian ini diaplikasikan dalam bentuk seesaw atau pengungkit yang merupakan salah satu bentuk pesawat sederhana dari lengan kuasa. Penelitian ini merupakan sistem kendali penjaga sikap pada seesaw diatur di 1 derajat kebebasan (DOF) yang ditetapkan sebagai setpoint pada kemiringan 0°. Kestabilan pada seesaw dikendalikan dengan metode kendali PID, yang merupakan sistem pengendali yang berfungsi untuk mencari nilai kestabilan sehingga respon sistem yang diperoleh dapat mencapai setpoint dengan baik. Maka dari itu diperlukan sistem penyeimbang yang dapat membaca sudut kemiringan pada lengan seesaw. Pembacaan sudut tersebut menjadi acuan kecepatan putaran baling-baling motor brushless dc (BLDC). Sensor yang digunakan adalah gyroscope. Sensor tersebut terdapat dalam modul IMU MPU-6050. Baling-baling menggunakan akuator berupa dua motor BLDC 920 kv kontroler berupa Electronic Speed Control (ESC). Setpoint ditentukan pada kemiringan 0° terhadap gaya gerak 1 DOF lengan. Motor BLDC kanan dan kiri melakukan variasi kecepatan putaran ketika pembacaan sudut tidak sama dengan setpoint. Motor BLDC kiri akan melakukan putaran CW dan motor BLDC kanan melakukan putaran CCW untuk membuat gaya angkat sehingga mencapai kestabilan. Pengaruh besarnya variasi kecepatan baling-baling yang diberikan yaitu berdasarkan besarnya nilai eror yang terjadi antara setpoint dengan input. Penelitian ini telah menghasilkan prototipe alat yang dapat bekerja pada kemiringan -30 derajat hingga 30 derajat dengan setpoint stabil pada 0 derajat. Dari perhitungan penalaan konstanta PID Ziegler-Nichols kurva reaksi didapat nilai Kp = 2,94, Ki = 1,2 dan Kd = 0,33. Dari hasil nilai penalaan tersebut didapatkan hasil stabil sesuai terhadap setpoint dengan hasil pengujian PID dengan nilai rise time= 18 detik, setling time= 7,5 detik, overshoot= 3,1%, peak time= 18 detik.]]>

<![CDATA[Kebanyakan fasilitas parkir tidak memberikan informasi bahwa parkiran sudah penuh sehingga membuat pengguna jasa parkir harus memakan waktu lebih dari 10 menit untuk menemukan slot parkir. Sistem parkir dirancang untuk membuka dan menutup portal secara otomatis serta memberikan informasi slot parkir yang harus dituju oleh pengguna jasa parkir pada sebuah layar monitor yang diletakkan sebelum portal masuk. Sistem ini juga mampu menampilkan jumlah slot parkir yang masih tersedia. Lampu indikator pada slot parkir berfungsi untuk memberikan indikasi menyala jika slot sudah terisi dan tidak menyala jika slot parkir tidak terisi. Indikasi ini menjadi parameter untuk tampilan informasi slot parkir yang harus dituju. Prototipe menggunakan pressure switch pad untuk mengaktifkan portal dan counter, motor servo sebagai penggerak portal masuk dan portal keluar, sensor LDR untuk mendeteksi keberadaan mobil pada slot parkir, LED sebagai lampu indikator, LCD sebagai layar monitor, dan seven segment sebagai counter dan menampilkan jumlah slot parkir yang masih tersedia. Angka pada seven segment berkurang jika mobil masuk dan bertambah jika mobil keluar. Prototipe mampu memberikan informasi bahwa parkiran penuh dengan menampilkan angka 0 (nol) pada seven segment dan informasi slot parkir FULL pada LCD. Portal masuk tidak dapat terbuka jika semua slot parkir telah terisi.]]>

<![CDATA[Modeling of a system is an important step for designing a good controller for a wheeled mobile robot. There are several techniques can be used gaining a model. One is deriving an analytical model mathematically. Another technique is by using system identification where the robot is given an input test signal and then measured the output signal. This technique, in general, is simpler compared to the analytic one. This paper described the modeling of a wheel mobile robot and used a gyroscope sensor as a feedback.The transfer function model of the robot is a second order system.]]>

<![CDATA[The manouver ability from one place to another in order to accomplish some tasks safely is a basic requirement of mobile robotics. Current robotic’s navigation systems require a ’real world’ map data, acquired by on-board sensors, to carry out simultaneous localisation and navigation (SLAM) algorithm. There are several SLAM algorithms. In this article we used SLAM gmapping using robot operating system (ROS) and laser scanner. The gmapping slam algorithm used particle filter method to localize robot pose within the environment and generate 2D occupancy grid map. The map is in gray-scale informed the free space, wall, and unexplored space. The implementation of gmapping slam conducted with turtlebot 3 from Robotics as well as 3D simulation using gazebo. ]]>

<![CDATA[An earthquake is a natural disaster caused by the movement of the earth plates or from below the Earth surface. The impact of the earthquake could lead casualties and other losses whether material or immaterial. The evacuation process of the victims must immediately proceed. The SAR (Search and Rescue) team has a duty to rescue victims who trapped in the rubble of the building. But information about the position of the victims could not be known precisely, and the environment around the location of the disaster is still very dangerous that might endanger the safety of SAR Team. In this research, a robot path pointer was designed to help SAR team in locating the victims. The method used in this research is the robot wirelessly controlled by SAR team at SAR team’s post with remote control. The robot searches in the rubble of the building and sends the victim’s location information to SAR team. This robot pointer research aims to find safe routes for SAR team of the victim’s location to reduce the risks that may harm the SAR team. The robot will give the main results of the pointer in the form of location coordinates and routes of the victim so that the SAR team only have to follow the route. Robot pointer guides the SAR team to the location of the earthquake in a short and less risky path for victim evacuation.]]>

<![CDATA[Abstract. We develop a smart digital advertisement board system which allows the system to display advertisements based on the majority of age and gender classifications of the consumers. The system captures the faces of the crowd and the face recognition techniques used to classify the majority gender and age of the crowd and then shows appropriate advertisement from the database to the advertisement board. A DNN model that is built, trained, and validated is used to recognize and predict the age and gender of the visible faces through image input or webcam using face photo dataset known as audience dataset. Several testing and analysis have been done onto the system in order to demonstrate the effectiveness and reliability of the system in displaying suitable advertisement for the public. The system can get gender accuracy of 77.82% and 86% for female and male respectively. And 68.78% accuracy for age recognition. The recognition speed is less than 1.3 second for up to 9 faces in an input image.]]>

<![CDATA[Efforts to enhance the quality of public services in Gampong Lam Ara, Aceh Province, were carried out through the development of a village information system (e-Gampong) and training for Gampong officials. Quality public services are considered crucial in evaluating government performance and creating a positive image in the eyes of the community. In an effort to provide more efficient and effective services, e-Gampong was developed to manage population data and other necessary administrative processes for the residents of Gampong Lam Ara. Additionally, intensive training was provided to Gampong officials to enhance their understanding of the smart village concept, Gampong management, Gampong digitization, and the utilization of e-Gampong. Evaluation results indicated that the implementation of the village information system and the training provided successfully improved the understanding and perceptions of Gampong Lam Ara officials and received a positive response from them. These results demonstrate that this approach succeeded in enhancing the quality potency of public services in Gampong Lam Ara and establishing a stronger foundation for realizing a smart village.]]>
