Bacteria are a group of living things or organisms that do not have a core covering. In the grouping, some bacteria are pathogenic. With a microscopic size, many pathogenic bacteria are found around and spread through the food eaten or by touching objects around them, then cause diseases such as diarrhea, vomiting, and others. As a more effective effort to help the government and society prevent disease caused by pathogenic bacteria, a system for the identification and classification of pathogenic bacteria K-Nearest Neighbor was created. This system uses a biological microscope that is attached to a webcam camera above the ocular lens as a tool to see bacterial objects and assist in bacterial capture. Rough player rotates automatically (auto-focus) in image capture. In the process of classification and identifying bacteria, the K-Nearest Neighbor method is used, which is a method with the calculation of the nearest neighbor or calculation based on the level of similarity to the dataset. In this study, the bacteria vibrio chlorae, staphylococcus aereus, and streptococcus m. with the highest accuracy is the K = 9 value of 97.77% using the Chebyshev method.

Solar thermal energy is one type of renewable energy, so this type of energy can be converted into other energy. This study uses a four-axis solar tracker with angle settings on the reflector to get optimal sunlight, scanning to determine the optimal lighting angle, measurement results are stored in real-time in the data logger. This study uses an LDR (Light Dependent Resistor) as a sunlight detector, equipped with several sensors, namely: current, voltage and power sensor (INA219), light sensor (MAX4409), and temperature sensor (DS18B20), and reflector angle as a parameter of solar efficiency panels. . The results showed that a four-axis solar tracker equipped with a reflector was able to increase the output power. The maximum power production produced by solar panels is: At a reflector angle of 300, the maximum power generated by a static panel is 143.43 W while a solar tracker is 175.15 W. At a reflector angle of 450 the maximum power generated by a static panel is 170.01 W and solar tracker 236.36 W. At an angled reflector of 600 the full power generated by a static panel is 87.77 W, and a solar tracker is 123.36 W. This study concludes that a solar tracker panel with an angle setting of 300 is more capable of maximizing power output than a static solar panel.

Protocol IEEE 802.15.4/ZigBee is a standard for low power personal network. This paper discusses about router, end device and coordinator using ZigBee protocol in term of distance and time to join. Testing carried out by pairing and On/Off method that constitute communication model from router or end device to coordinator. The result showed that with pairing methods could far distance until outside building with further distance about 65 meters, while the distance using On/Off method can reach few room in indoor area. Longest time to join need about 1 minute 15 seconds. Compare with pairing method that always connected, On/Off method need more time to connect in ZigBee Network.

Kemacetan adalah masalah yang sulit di selesaikan oleh beberapa kota. Maka dari itu pemerintah merestrukturisasi angkutan umum seperti bus, kereta api, dan MRT, dan perbaikan trotoar bagi pengguna jalan kaki. Bagi sebagian orang sadar untuk berjalan kaki untuk menempuh jarak yang dekat, namun berjalan kaki membutuhkan waktu yang lama dan membutuhkan tenaga yang lebih. Skuter listrik merupakan salah satu inovasi yang dikembangkan sebagai sarana transportasi jarak pendek. Scooter ini dirancang dengan tujuan penggunaan pada lingkungan dimana pada tempat-tempat tersebut terdapat banyak aktivitas berpindah tempat sehingga nantinya dapat meningkatkan produktifitas waktu. Maka dari itu di buatlah skuter listrik untuk mengatasi masalah tersebut. Untuk membuat alat ini membutuhkan beberapa komponen yaitu Arduino uno, Bluetooth, modul regulator stepdown, dan sensor inframerah

In this digital era, technological development is one of the main developments in human life today. And along with the times, there is drone technology which is currently becoming popular among the wider community with its ability to take photos and videos.[1] One of the technological innovations that are developing in the current era of globalization is drone technology which in military terms is also called Unmanned aerial vehicle (UAV) is a type of aircraft that can fly without a crew. The waypoint method works by finding the coordinates of the position to be addressed and then returning to the initial position. Autonomous is an autopilot mode with reference to GPS coordinate data on electronic devices that can move automatically without using a remote control in its movement. In the process of carrying out an autonomous drone mission, it requires several steps in which there are hyperlapses, waypoints, and intervals. From the results of testing autonomous missions on the DJI Mavic 2 Combo drone, a conclusion can be drawn where the drone is able to carry out its mission correctly. Di era digital ini perkembangan teknologi merupakan salah satu pokok pembangunan dalam kehidupan manusia saat ini. Dan seiring dengan perkembangan zaman, terdapat teknologi drone yang saat ini menjadi populer di kalangan masyarakat luas dengan kemampuannya yang dapat mengambil foto dan juga video.[1] Salah satu inovasi teknologi yang berkembang pada era globalisasi saat ini adalah teknologi drone yang dalam istilah militer disebut juga dengan Unmanned aerial vehicle (UAV) merupakan jenis pesawat yang dapat terbang tanpa awak. Dengan metode waypoint bekerja dengan cara mencari titik-titik koordinat posisi yang akan dituju kemudian kembali ke posisi awal. Autonomous merupakan suatu mode autopilot dengan acuan dari data koordinat GPS pada perangkat elektronik yang dapat bergerak secara otomatis tanpa menggunakan remote controle dalam pergerakannya. Dalam proses menjalanan misi autonomous drone membutuhkan beberapa langka yang didalamnya terdapat hyperlaps, waypoint, dan interval. Dari hasil pengujian misi autonomous pada drone DJI Mavic 2 Combo dapat ditarik sebuah kesimpulan dimana drone mampu menjalankan misinya dengan tepat.

In the cultivation of rice, there is never a problem with the name pests. If not controlled, the pest attack will affect the productivity level of the plant. Pests that attack rice plants include leafhoppers and birds. Birds have a very large percentage rate in attacking rice plants, namely the bondol bird which is one of the grain-eating birds. This bird is a very troubling pest for rice farmers because it causes crop yields to drop dramatically. There are several ways to repel birds, usually farmers using the manual method by making a rice field and crackle which is then tied to a rope. When using this method, farmers have to wait for agricultural land for approximately one month. This is considered inefficient considering the farmer's job is not only to wait for the rice plant until harvesting. So that in this study, a tool that will be used to repel bird pests will be designed by using solar panels as a source of voltage with sound output using a frequency of 1.5 - 3 KHz.

Electronic devices that are increasingly developing make alternatives to human activities every day so that human work can be completed easily. Like smartphones as electronic devices that have dominated electronic devices so that users have the convenience of fulfilling their needs. There have been many electronic devices that can be controlled by simply pressing the remote button without even touching anything but by voice commands. Technology has developed rapidly so that a microcontroller like Arduino can be integrated with other devices, such as an electric car that is equipped with solar panels as a source of electrical energy and controlled via an Android smartphone. In this study, an electric car will be controlled by an application on a smartphone with voice commands, and using bluetooth as a connection between the application system and the electric car system.
