Abstract

The spin coating technique can produce very thin layers by utilizing centrifugal force,linear shear stress and uniform evaporation of the solution on a rotating disk or substrate.The thin layer produced by the spin coating method has a high level of homogeneity. Thedesired thickness and quality of the coating can be controlled based on the viscosity orviscosity of the solution, material content, time, and speed of rotation of the spin coater.The research method used to develop this research is the instrumentation research methodof the spin coating device which detects spin on the disc. This system uses an ESP32Microcontroller, Hall effect Magnet Sensor, Diodes, DC Motor, LCD 165x2 i2c, Mosfetand smartphone. The results obtained are that this Spin Coating tool can rotate with amaximum speed of 3000 rpm, and a minimum speed of 1000 rpm. Although there is stillnoise at certain speeds caused by the less stable data transmission process and lesssensitive response from the sensor, as a whole, the spin coating tool can rotate at a certainspeed by monitoring using android.

Abstract

The use of a barcode scanner system on Android is applied to facilitate the user or users in accessing a system where in this system the barcode scanner serves as the initial key to accessing a safe. Research and evaluation results show that the use of QR Code (Quick Respone Code) can store numeric data types up to 7,089 characters, alphanumeric data up to 4,296 characters, binary codes up to 2,844 bytes and kanji letters up to 1,817 characters. QR Code is also resistant to damage, because QR can correct errors up to 30%, so the use of QR Code on a system can increase the speed of work and accuracy of detection on the system.

Abstract

The development of the world of robotics in Indonesia is experiencing very rapid development compared to a few years ago, the use of PID Control-based technology is growing in the field of robotics. This line follower robot uses IR Line follower sensor to detect the black line and PID control to regulate the movement of the robot automatically, so that the robot can follow the line that has been made with direction. The Arduino Uno microcontroller in this robot design is the main part of the input and output control system. In this robot design, Arduino Uno is used as a microcontroller to control sensors that function as sensing / detection tools for robots. The working system of this robot is: how to run it by activating the power button on the back of the robot. The number of sensors and the accuracy of the PID control value can affect the comparison of the robot's travel time value from the starting point to the end of the test with two paths that have been tested, the results obtained 4 IR LF Sensors with an average travel time of 6.7 seconds on the first path and 13.5 seconds on the second path, better than 2 or 3 IR LF Sensors which have a difference of 0.64 seconds on the first path and 0.7 seconds on the second path. The above values can change according to the influence of component specifications, circumstances and robot environment during testing.

Abstract

Abstrak- Program pengabdian ini dilaksanakan di Desa Seuseupan, Kecamatan Caringin, Kabupaten Sukabumi, sebagai respons terhadap dua permasalahan utama, yaitu rendahnya produktivitas pertanian akibat metode konvensional dan keterbatasan penerangan publik yang menghambat aktivitas sosial-ekonomi. Kegiatan dirancang untuk memperkuat ketahanan pangan dan kemandirian energi desa melalui penerapan teknologi Internet of Things (IoT) pada sistem pertanian serta instalasi solar panel pada ruang publik. Metode pelaksanaan mencakup observasi lapangan, Focus Group Discussion, pelatihan teknis, pembangunan Green House Smart Village, pemasangan lampu tenaga surya, serta monitoring dan evaluasi. Implementasi smart farming berbasis IoT menghasilkan peningkatan hasil panen sebesar 28%, efisiensi penggunaan air 35%, serta penurunan kerusakan tanaman. Penerapan solar panel di titik strategis desa meningkatkan keamanan malam hari, menekan biaya listrik hingga 37%, dan mendorong pertumbuhan aktivitas ekonomi sebesar 23%. Pelatihan yang diberikan kepada petani dan perangkat desa meningkatkan pemahaman teknologi lebih dari 90%, serta mendorong terbentuknya Kelompok Tani Cerdas Seuseupan sebagai pengelola keberlanjutan program. Secara keseluruhan, kegiatan ini menunjukkan bahwa integrasi IoT dan energi surya mampu memperbaiki kualitas pengelolaan pertanian, memperkuat infrastruktur energi, dan meningkatkan partisipasi masyarakat. Program ini membangun fondasi desa cerdas yang mandiri secara pangan dan energi, sekaligus membuka peluang perluasan inovasi ke desa-desa lain dengan karakteristik serupa.
