Currently, the use of microcontrollers is very diverse in helping make work easier. A microcontroller is also a microprocessor circuit system that consists of CPU, Internal Memory, Internal Beat Circuit, and I/O Terminal. All parts of the system are integrated into one single chip to get the maximum benefit from the microcontroller.In the industrial world, humans are greatly helped by the machines that have been created. One very useful machine is a CNC machine. This project utilizes a microcontroller as an automatic control on a CNC machine which aims to help simplify the programming of input files or data needed to move a CNC machine. The ball screw is used to convert the rotational motion generated from the stepper motor into a translational motion to move the working axis of the CNC machine. Designs that have been drawn on a personal computer will be converted into a G-Code form and then converted into microcontroller programing language using Inkscape application. The microcontroller uses a Pronterface application to read the data that has been transferred by the personal computer. Then this data is used to drive the two stepper motors, and a pattern is formed on the plane according to the design.The result of this CNC machine is to use a pen as an assumption of the drill bit, the precision of the distance traveled according to the input, and the milling experiment in the form of a certain image or writing.

Desa Sunten Jaya, Kecamatan Lembang, Kabupaten Bandung Barat, merupakan desa yang memiliki banyak potensi. Namun potensi tersebut belum didukung dengan adanya bimbingan dan pengarahan untuk memaksimalkan potensi tersebut. Dengan menggunakan pendekatan wawancara dan diskusi, kelompok Pengabdian Kepada Masyarakat Universitas Sangga Buana bekerjasama dengan Universitas Kebangsaan mencoba untuk membantu mengembangkan potensi tersebut. Salah satu solusi yang ditawarkan adalah dengan membuat Website Penjualan untuk memasarkan hasil perkebunan dan industry kecil-menengah Desa Sunten Jaya. Dengan adanya kegiatan Pengabdian Kepada Masyarakat ini diharapkan dapat membantu masyarakat Desa Sunten Jaya untuk mengelola dan mengembangkan potensi desa mereka.

The purpose of this prototype is to develop a stator winding mechanism with a helical method, to reduce the electromagnetic force and decrease stator winding temperature rise. The prototype is divided into mechanical systems using a slider-crank mechanism that controls the wire movement with a worm gear arrangement. The other side is a control system that rotates two-cylinder, the stator winder cylinder, and the wire shaft shifting so that the coil is stacked helically in each layer. This prototype design has been made and the stator winding temperature increase is tested with 2.5 Celsius degrees on the average, with the baseline of temperature increase less than 10 Celsius degrees form the ambient temperature.

Cases that occur complaining about the engine on the vehicle is abnormal, both in idling and high rpm, when the initial inspection is carried out, there appear to be abnormal symptoms on the vehicle's engine. So it needs repairs to the vehicle where there is a problem in the vehicle, which complains about the abnormal state of the engine both the state of idling or middle and high rpm. After doing repairs, the problems that occur occur. The water hammer is caused by a cowl top seal that has no locking clip and water filter assembly. As a result of the water hammer being produced, there is damage to the components inside the cylinder block, namely the cylinder liner and piston rod. Keywords: Abnormal, When Idling, High Rpm
