Abstract

This study is intended as a source of learning and research will design and comfort safety System gymnasium-based microcontrollers. Existing gym until now still has a weakness for several factors such as weather changes rapidly, visitors are crowded, and the level of public awareness of the order is still lacking, so will implications for the safety and comfort for users of building itself. The method is a method of research literature and methods of laboratory studies. Literature study was done by studying and looking for articles on matters relating to the development of world sports stadiums that are considered to have the required criteria. For laboratory study done by making the design of hardware and software is also used in this study. This system used sensors to detect the rainy weather conditions, detect the light intensity to keep the lighting inside the building, limiting the number of visitors in accordance with the capacity building capacity, temperature rise resulting from a user density of buildings and also a fire hazard that could have been either intentional or unintentional. Entirety of the sensor arrangement is controlled by a microcontroller. It is expected that by using this system, users are building (football stadium) will feel more secure and convenient to activities inside the building.

Abstract

In a highly competitive industry faces today ranging from small or home-based printing to using machine that can print offset a hundred thousand copies per hour. But, the increasing competition resulted in requiring a faster production time from order entry, print proff until the production process to delivery to customers. Often times in case of orders which will result in the concurrent PPIC will experience vertigo in the setting of production schedules which have concurrent delivery time. Often will end up with no receipt of orders due to difficulties in the production schedule, especially if the orders require the same offset machine and cylinder wear the same length, while the number of cylinders is limited. Therefore, the printing company should be able to do so in the conduct of a penetration timing of production can easily be simulated and implemented on the ground. CBS (Base Constraint scheduling) is a technique to do the scheduling of production so that production can be carried out smoothly and quickly that fulfill the promise made to customers. In scheduling, there are several techniques that can be used are: FCFS (First Came First Serve), EDD (Earliest Date), and LCLS (Last Came Last Serve). So, it is required to be able to do way better scheduling to get results quickly in this fast changing schedules.

Abstract

Basically, the water wave (wave) that passes through uneven base will have a solution to the wave transmission and reflection. It has been found also that the sinusoidal basis with certain conditions can cause the Bragg resonance. This paper will show that the wave propagation through the wall of river water can also cause sinusoidal Bragg resonance. Bragg resonance will occur if the sinusoidal wall of the wave number twice the number of incoming waves. Both analytically and numerically, the river wall with amplitude sinusoidal small amplitude can be reduced significantly due to the Bragg resonance. More specifically, the situation would be different if we consider the river mouth in the form of a hard wall of the dam. The existence of the hard wall of the dam at the mouth of the river it can cause the amplitude of the waves crashing against the transmission of large dams increased many-fold.

Abstract

The purpose of this study was to identify problems and weaknesses in the payroll information system, providing recommendations to reduce the risk of existing problems and produce audit reports for companies. Research method used is through literature study, interviews and observation. Audit method used is the method of auditing around the computer. Analysis was performed by analyzing the findings of problems, risks, and recommendations on the findings of the problem. After doing research, we conclude that there are still some weaknesses in management control and application control. But companies should be more focus on the weaknesses inherent limitations in controlling the application and control the output. Based on these findings, suggested that the company to rectify existing weaknesses and enhance control over payroll information system.
