Abstract

PID control has been widely used in industry  as well as been implemented in the control of the liquid level . The research objective is to design  PID controller base on microcontroller  and then apply it on the miniature hopper-conveyor plant to maintain solid levels of raw materials to remain constant . The dimension of hopper is 25 cm long, 20 cm wide and 25 cm high. The design of PID control uses a separate action based on microcontroller and for the  tuning uses open-loop Ziegler-Nichols. The design is implemented in miniature hopper-conveyor plant to move the raw material form of green beans to the hopper using a screw conveyor. The screw conveyor is  rotated by a three phase induction motor with inverter speed drive. Level in the hopper is measured by using an ultrasonic sensor module build-in the data acquisition program . The experimental results of implementation on the miniature hopper-conveyor plant shows that PID control provides good performance such as overshoot occurs in  1 cm, or 0.05 % of set point and risetime shows 280 seconds. Key words: PID controller, microcontroller, Ziegler-Nichols, Hopper-conveyor plant

Abstract

Motorbikes are motorized vehicles that have two wheels. in a straight line lined up so that when the conditions go at high speed it remains stable because of the gyroscopic force. Moving at high speeds continues to run stable and at low speeds stability always depends on the settings. In Indonesia motorbike users are very popular because they are cheap, easy to reach, save fuel and the maintenance costs are not large. One of the most famous motorbikes in Indonesia is Yamaha with its founder from Japan named Yama Tarakusu. Yamaha motorbike is a service for consumers in providing motorized vehicle maintenance because it is designed by reliable experts. Yamaha Motor Trade Expo Showroom Simalungun Regency dealers selling motorcycles, spare parts while providing service services for consumer motorcycle vehicles have not been maximized and have not been satisfactory because they are still done manually on sales, especially in selling spare parts because there is no fast and accurate information regarding stock or inventory. In terms of service services, there is also no application system running at the Yamaha Motor Trade Expo Showroom in Simalungun Regency. The design of sales and service applications aims to facilitate and accelerate the sales data processing and motorcycle service, so that the administration of sales and information is faster and more accurate. Departing from this, the author designed the application of sales and service services at the Yamaha Motor Trade Expo Showroom in Simalungun Regency in the hope that sales applications and service services can provide fast, precise and accurate information.Keywords : Sales, Motorcycle Services, Microsoft Visual Studio 2010, MySQL

Abstract

Vending machine is one of hardware that the system was build using an object oriented approach. Almost half of human job related with it, then the development system of automatic machine getting fast to adapt human needed nowdays.Visual Modeling is the process of taking the information from the model and displaying it graphically using standar set of graphical elements. The standard is vital to realizing one of the benefits of visual modeling: communication. Communication between users, developers, analysts, testers, managers and anyone else involved with a project is the primary purpose of  visual modeling. We can use Unified Modeling Language when make visual modeling. UML is industry-standard modeling notation for object-oriented system, and is the premiere platform rapid application development. One of the primary advantages of the object-oriented modeling is the ability  to build components once and then use them over and over again. We can reuse a basic piece of object-oriented design code in desired system.All in all, visual modeling make easy in implementing software of vending machine those it can increase work time efficiency in developing a vending machine system especially, and generally fulfill human need nowdays. Keyword : Vending Machine, Unified Modelling Language
