Pemanfaatan mikrokontroler untuk menunjang pekerjaan manusia serta didunia industri menuntut adanya perkembangan dalam hal ketepatan, kecepatan serta teknologi yang terbaru. Raspberry Pi merupakan papan tunggal single board circuit (SBC) seukuran kartu kredit yang dapat digunakan untuk menjalankan program perkantoran, permainan komputer, sebagai pemutar media beresolusi tinggi serta menjadi mikrokontroler. Dengan menggunakan bahasa pemrograman PYTTHON yang mudah dipahami dan populer, Raspberry Pi dapat dengan mudah dalam pengembangannya. Salah satu penggunaan Raspberry Pi yaitu sebagai mikrokontroler robot lengan yang digunakan oleh manusia untuk mengangkat benda berat atau membutuhkan perpindahan yang mempunyai jarak jauh. Prototype Robot lengan dibuat menggunakan motor penggerak yaitu 1 servo Tower Pro MG996R dan 3 mini servo MG90S serta 4 buah potensiometer sebagai kendali manualnya. Robot difungsikan untuk memindahkan benda secara manual yaitu dengan memutar potensiometer. Berdasarkan hasil penelitian yang telah dilakukan robot lengan dapat memindahkan barang dari titik tertentu ke titik yang lain dengan berat kurang dari 90 gram dan benda berdimensi kurang dari P=60mm, L=36mm dan T=44mm. Mikrokontroler Raspberry Pi Zero W dinilai sangat efektif dalam menjalankan fungsinya, dalam pengembangannya Prototype Robot Manipulator 4DOF Berbasis Raspberry Pi Zero W dapat dengan mudah dikembangakan sesuai dengan kebutuhan manusia.

Raspberry Pi is a single board circuit (SBC) the size of a credit card that can be used to run office programs, computer games, as a high-resolution media player and a microcontroller. By using the PYTTHON programming language that is easy to understand and popular, Raspberry Pi can be easily developed. One of the uses of Raspberry Pi is as a microcontroller robot arm that is used by humans to lift heavy objects or require long distance movements. Prototype Robot arm is made using a drive motor namely 1 servo Tower Pro MG996R and 3 mini servo MG90S and 4 potentiometers as manual control. The robot functions to move objects manually by turning the potentiometer. Based on the results of research that has been done robot arms can move things from one point to another with a weight of less than 90 grams and objects with dimensions less than P = 60mm, L = 36mm and T = 44mm. The Raspberry Pi Zero W microcontroller is considered to be very effective in carrying out its functions, in its development the 4DOF Prototype Robot Manipulator Based on the Raspberry Pi Zero W can be easily developed according to human needs.

The purpose of this study was to determine the potential talents in the sports field of students at SMP Negeri 1 Andong Boyolali Regency in 2020. Knowing whether or not the student has a sports potential in the sports they are participating in. This type of research is descriptive quantitative, using test and measurement techniques. One-shot case study research design. The population in this study was 217 students, the sample of this study was 50 students who were taken by purposive sampling. The instrument used is the Sport Search method. Based on the results of the study, it can be concluded that the talents or hobbies of the students include soccer as many as 33 students or 66%. According to 7 students, 13 students did not match, and 13 students did not match. Volleyball sports as many as 15 students or 30%. According to 9 students, less suitable for 1 student, not suitable for 5 students. Basketball as many as 2 students or 4%. According to 0 students, less suitable for 0 students, not suitable for 2 students. The total number of students who are not suitable and not suitable is 34 students or 68%. Has the potential in the sport of fast walking 9 students or 18%, high jump 10 students or 20%, 10 students or 20% shot put, 5 students running or 10%. Suggestions: (1) Physical education teachers are able to guide and direct students' talents. (2) Students are expected to join sports clubs.
