In this study, the application of temperature and air circulation control in the smoking room using a microcontroller. The Sensors applied to this Prototype are LM35 and DT-Sense CO. The method used design a controller and then apply it to the microcontroller. The sensor has been tested on a miniature smoking room. The results show sensors can work and good, although cigarette smoke and the temperature of the room changes, so air quality in the smoking room can be maintained. Index Term-Cigarette smoke, CO, automation, microcontroller, temperature sensor, smoke sensor
Tank is a war vehicle made of steel that can be operated on various fields. With various fields and a large amount of terrain that the tank had to pass, this made it necessary for the tank to be able to stabilize the cannon so that the cannon be able to fire right on the target. This study discusses the stability of the position of the cannon on the tank prototype using the PID control system. PID values are obtained by using the Ziegler-Nichols tuning formula and simulink. The system using Arduino MEGA 2560 as microcontroller, gyroscope & accelerometer for the feedback sensor and cannon that driven using three servos that representing the x-axis, y-axis and z-axis. The highest average error value is 4.67 degrees with an overall average value of 2.29 degrees and an accuracy percentage of 98% when the tank tilted randomly on the x-axis, y-axis and z-axis.
Jumlah area Desa Lengkong Kulon adalah 15331 km2. Desa Lengkong Kulon ini merupakan desa berkembang yang pada saat ini wisata yang akan dikembangkan pada desa ini adalah wisata religi, wisata kuliner, wisata air, dan dari segi ekonomi. Namun dari beberapa pengembangan tersebut, desa ini membutuhkan pengelolaan sampah. Sampah merupakan hal krusial bagi kehidupan dan kesehatan masyarakat. Di area yang luas tersebut terdiri dari beberapa RW yang memiliki kebijakan tersendiri untuk pengelolaan sampahnya. Ada yang melakukan pembakaran sampah, ada yang bekerjasama dengan pemerintah daerah untuk pengangkutan sampah, dan ada pula yang membuang sampah pada lahan kosong. Dari segi kesehatan untuk proses pembakaran sampah dan membuang sampah sembarangan memiliki dampak buruk, karena dapat mengakibatkan pencemaran lingkungan bagi masyarakat sekitar. Solusi yang ditawarkan dengan Program Kemitraan Masyarakat ini adalah dengan memberikan penyuluhan terkait pengolahan sampah, peminjaman mesin pencacah sampah organik dan anorganik, dan pengawasan dalam pemanfaatan mesin tersebut. Desa Lengkong Kulon memiliki bank sampah yang akan dikelola oleh pemuda-pemudinya. Bank Sampah ini adalah wadah bagi masyarakat untuk mengubah sampah yang mereka miliki menjadi uang. Dengan adanya mesin pengolah sampah, maka harga jual sampahnya akan lebih tinggi dibandingkan jika penjualan sampah sebelum diolah.
Abstract— Tanks have an important role in protecting a region in the event of a battle. The tank's cannon is a very reliable weapon in warfare. However, the cannon's precision while aiming and firing targets is a concern. A control system must be created to increase the cannon's stability and precision. The state feedback control technique with a full-state observer is the control system that can manage cannon disturbances. The control system is built around three DC motors, each of which operates the cannon’s x, y, and z axes. Then performed tests for each axis at an angle of 90 degrees, The state feedback control with a full state observer can produce outstanding performance, with the time required for the cannon to reach the target angle was 0.51 seconds, and the cannon system had 0% overshoot.
