Abstract

Everyone who wants to borrow money either for business capital or for personal needs will definitely borrow from the bank. Borrowing money from public banks is commonplace, but borrowing money from Islamic banks is only used by some people who know about Islamic banks. The difference from borrowing money from a commercial or Islamic bank lies in the specified usury. To make it easier for customers to find out what sharia loans are like, they can use cellphones (HP). That's why this sharia loan information application via mobile phone was made. For the design process, the JWTK application software will be used and the KToolbar will be used. The design of handheld devices software is designed based on the displays needed. The display consists of menus that will make it easier for users to search for sharia loan information. It's very easy to use, just choose what type of loan you want. After that, enter the input in the form of a number and then by pressing the Wrung button, the output will automatically display the calculation results from the input. J2ME (Java 2 Micro Edition) technology is used because this technology is platform- and device-free. In addition, the memory used is very small, so it doesn't take up too much memory on existing cellphones and the installation process is so easy.

Abstract

In an industry it is often necessary to have an automatic control in every industrial process. Misainya in chemical companies. Where each industrial process requires the mixing of several chemicals in liquid form continuously all at once and in each mixing constant and controlled circulation is desired. So we want a tool that can be used to regulate the circulation of water and control it constantly and monitor the volume of liquid from the control center without having to visit each of the mixing tanks. This system uses the MC68HC908KX8 microcontroller made by Motorola included in the 8-bit processor as the central controller. The im water circulation control system consists of several controller circuits including keypad circuits, water sensor circuits, microcontroller circuits, display circuits, and driver circuits for motors and pumps. The process starts from reading the water sensor, where this sensor is in the form of a probe that is installed sequentially from the bottom to the top of the tub with a level level from 0 to 8. The output from this water sensor is fed to the microcontroller which will eventually be displayed on the water level display. In addition to reading the water level and sensor, the m.krokontroler also looks at the desired water level request according to the level selection from the selection button displayed on the button display. During the control process, the microcontroller will always see a display where the selection number will be used as a reference for the microcontroller to maintain the water level according to demand. The water level sensor system used is very good for salt water and not so good for clean water or bathroom wastewater. The size of the work area on this tool is still relatively imperfect, because the wiper motor and water pump as input output water use little power. Besides that, the water sensor used is simple and made of iron wire which corrodes easily. So it is necessary to develop the use of a motor with greater power and a water sensor that is anti-corrosion, capable of detecting and working well for any liquid.

Abstract

Today, industrial competition is increasingly competitive and complex, along with advances in science and technology that are increasingly integrated. So like it or not, every company competes to continue to improve the company's performance so that it continues to exist in the competitive arena. The classic problem experienced by each company is the limited human resources and technology they have, so optimizing the conversion of resources such as: Labor, Raw Materials Energy Capital and technology should be the main focus in company policies so as to create a life cycle and company performance that is healthy so that it can provide maximum benefits and have high competitiveness. Productivity analysis using the American Productivity Center Model (APC Model) approach is a productivity analysis based on index numbers that can provide an overview of the company's productivity and profitability growth and can provide information to company management about which resources or inputs are not optimal in conversion. which causes a decrease in company performance so that improvement steps can be taken early and continuously. Research results at PT. Mirasa Indo Food Industry which is located at JI. Munggur No. 2 Ambar Ketawang, Mungkid, Magelang. During the period 2002 to 2003, it turned out that in 2003 productivity decreased by 3.34% while profitability increased by 23. 22% in 2003 there was also an increase in the total input of 1.266%. From the results of the research that has been done, it can be seen that the productivity level has decreased and the profitability has increased.

Abstract

Ultrasonic sensors are widely used in various fields of application such as car alarm systems, automatic door controls, measuring the level of viscosity of liquids, measuring the tensile force on screws and others. In this study, ultrasonic sensors were applied to manufacture digital distance measuring devices that resonate at a frequency of 40 KHz above the threshold of human hearing. Ultrasonic sensors are made of piezoelectric material which has two properties, namely direct piezoelectric properties and reverse piezoelectric properties, then the sensor will change the physical quantity to electronic quantity. The principle of this tool is shooting pulses from the transmitter with the TX sensor until it hits the object to be measured until it returns to the receiver with the RX sensor. By measuring the length of time it takes for the transmitted wave to return to the sensor, then calculates the target distance using the speed of sound in the medium (air), then the conversion value will be obtained in the form of the distance. Object detection by ultrasonic sensors is influenced by several factors such as the characteristics or ability of the sensor system to reach objects, the surface area of ??objects and environmental conditions such as air humidity and temperature. This tool uses a seven/segment display as a display of measured distance values, with changes in distance every 0.01 meters, with the closest detectable measuring distance of 5 cm and the farthest measuring distance of 300 cm.

Abstract

Image visualization is very much needed in a study. To obtain this visualization, it can be done in various ways. One of them is by utilizing ultrasonic waves to represent the shape of an object. In this paper, it will be revealed how a signal or ultrasonic wave can be converted into data in the form of a visualization display that can be understood by humans. Imaging the shape of objects using ultrasonic waves is a short analysis of how ultrasonic waves through signal processing can produce data, which in this case is an image. The yarn* system design used is a combination of hardware and software UrLrin,fS , Ultrasonic Transmitter and Receiver, MC68HC908GP32 microcontroller, MC74HC595A shift register, PPI 8255 interface and uepeIr^tn^0mpUter Se6an^^ The software used is \VinIDE_GP32 and Borland C++ Builder version 4. This system starts working when the microcontroller gets a response from the computer. The microcontroller will function as a system controller and data processor. The data obtained from the ultrasonic receiver is then processed to be converted into grayscale color. The data is then sent to the computer via the MC74HC595A and PPI 8255. The final image results are obtained by rearranging the data based on the order of pixels!. In this study the object used as a reflective object is a toy candle in the form of a block. cubes, spheres and prisms. The ultrasonic firing distance is selected 2cm, 5cm and 9cm. The final image obtained is a 2D image with a canvas size of 10 x 10 pixels and a gray scale image sharpening technique.
