Abstract

In this final project, a temperature and humidity control system for aircraft component storage has been designed using a PID controller and ON/OFF controller. This system is designed so that the warehouse component storage temperature of aircraft components, especially the avionic component (aviation electronic) which has a storage requirement at a temperature of 16-26 °C and humidity at 40-65% maintained at the reference temperature, so that the quality and state of components stored in the warehouse will stay awake his life span and abilities. The control system that was designed consisted of 1 unit 12VDC 10A power supply, 1 unit DC-DC Converter, 1 unit Arduino Uno microcontroller board, 4 DHT22 sensors, 1 unit 2 Channel Relay, 1 unit 180 ° servo motor, and 1 unit dehumidifier. The reference temperature is set at 24 °C and the reference humidity at 60%. The control system consists of a PID controller to control temperature and an ON / OFF controller to control humidity. When the warehouse room is fed with a central AC (air conditioner) flow, the sensor will read the temperature and humidity of the room. The sensor readings will be sent to Arduino to be compared with a predetermined set point. The temperature error value will be processed by the PID with an output control signal in the form of a PWM signal (50Hz) to control the rotation of the servo motor used to open or close the central AC flow. While the humidity error signal will be processed by the ON / OFF controller with an output signal in the form of an ON or OFF state for the relay that is used as a switch for the dehumidifier. The test results with the PID parameter values ​​Kp=75, Ki=40, and K =45 obtained by the heuristic method produces a good system response. The temperature can be controlled between 24 °C - 26 °C and humidity can be lowered when it is above 60%.

Abstract

Kehidupan modern saat ini telah sepenuhnya berhubungan dengan energi listrik. Tetapi masih banyak pengguna/konsumen listrik yang masih awam dengan hal yang satu ini. Tindakan nyata Universitas Budi Luhur khususnya Fakultas Teknik secara terstruktur lewat institusi, secara rutin melakukan aplikasi IPTEK yang langsung menyentuh masyarakat namun masih belum terasakan secara signifikan. Berbagai permasalahan yang dihadapi masyarakat tampaknya ada yang luput dari perhatian Fakultas Teknik. Masyarakat luas sangat berharap Fakultas Teknik dapat berkiprah lebih banyak dalam memecahkan berbagai permasalahan yang ada di masyarakat. Dengan berkembangnya teknologi yang semakin modern, listrik mempunyai peran yang sangat penting dalam kehidupan maupun dunia industri. Melihat kondisi masyarakat yang masih belum paham betul mengenai cara menghitung KWH Meter ini dan cara menghemat energy pemakaian listrik, maka perlu adanya suatu sosialisasi yang dapat membuka jendela wawasan masyarakat agar dapat lebih mengetahui dalam penggunaan listrik sehari hari. Oleh karena itu dilakukan “Penyuluhan Teknik Penggunaan Listrik Hemat Energi dan Cara Menghitung Tagihan Listrik dari KWH Meter” yang dapat membekali masyarakat dalam penggunaan listrik dalam kehidupan sehari-hari.

Abstract

The wheeled robot used to deliver documents between rooms must be able to move according to the environmental conditions of the work area. For this reason, the robot must have knowledge of the conditions of the work environment to be passed. In this final project, the work area environment mapping on the wheeled robot is carried out. Mapping was done using the Simultaneous Localization and Mapping (SLAM) method. The equipment used in the mapping is a lidar sensor. The robot system consists of a raspberry Pi 4 which is used as the main controller of the robot. The robot has two sensors. The first sensor is a lidar sensor, which is used to detect the distance of the object in front of the robot. Then the IMU sensor is used to detect the robot's orientation and position changes. In the robot there is a motor driver which is used as a robot control signal processor to drive a DC motor. Map making is done by means of a lidar sensor reading the robot's working area environment. The lidar sensor output signal is processed using the SLAM gmapping method. In this test, to determine the environment of the robot's work area, using a laser scanner to produce a two-dimensional (2D) map, while estimating the position of the robot on the map using a particle filter. This simultaneous mapping uses the Simultaneous Localization and Mapping (SLAM) mapping algorithm based on Raspberry Pi 4. The results obtained are maps in grayscale. In addition to SLAM gmapping, this article also shows that there are one to three robot position 2D testing arenas.

Abstract

Abstrak: Pengolahan sampah sangat penting untuk mencapai kualitas lingkungan yang bersih dan sehat dengan demikian sampah harus diolah dengan sebaik mungkin. Salah satu teknologi yang dapat digunakan untuk mengolah sampah menjadi senergi terbarukan yakni teknologi biodigester. Banyak manfaat pengelolaan sampah bagi kehidupan. jika sampah dikelola dengan baik dapat digunakan kembali. Dalam mengolah sampah menjadi energi terbarukan dilakukan dalam beberapa tahapan yaitu tahap persiapan, tahap perancangan dan pembuatan biodigester, tahap pembuatan biomass, tahap ujicoba dan monitoring hasil. Biodgester mini dibuat dengan menggunakan tong sampah kecil ukuran 60liter yang umum digunakan di setiap rumah. Sampah organic yang digunakan adalah sampah sayuran dan buah-buahan yang dicampur dengan kotoran sapi. Uji coba berhasil dengan baik, lebih dari 80% warga dapat menerima materi dan mengaplikasikannya. Untuk mendapatkan gas dengan baik, diperlukan jenis tong sampah yang tepat dengan penutup yang memiliki ulir sehingga dapat menutup rapat agar proses pembentuk biogas berjalan sempurna.Abstract: In this community service activities are presented as assistance in the manufacture of household-scale mini bio digesters. The activity was carried out in the neighborhood of RT. 002 RW 016, Paninggilan, Ciledug, involving approximately 10 heads of families. The activities are carried out in several stages, namely the preparation, design and bio digester manufacturing, the biomass production, the trial and yield monitoring. The mini bio digester is made using a small 60liter trash can that is commonly used in every home. The organic waste used is vegetable and fruit waste mixed with cow dung. The trial was successful, more than 80% of residents were able to accept the materials and apply them. To get good gas, needs the right type of trash can with a lid that has a screw so that it can close tightly so that the biogas forming process runs perfectly.
