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.

Abstract

This report discusses about the administration service at House of Medicinal Treatment in Central Office of The Ministry of Agriculture Republic of Indonesia. The administration service build in a web-based system, which has changed the administration system from manual to computerized. This system, which is known as Clinic Information System, facilitate the employee at House of Medicinal Treatment when they do their medical service in clinic from patient registration, medical record and report. The conclusion of this report is that the employees in the house of medicinal treatment is assisted enough with the design of this web-based system, but the function and the accuracy of the system should still be improved.

Abstract

Indonesia today is still a State agrarian. Thus agriculture in Indonesia always get more attention by the government. Many government programs are rolled out to support the agricultural development of Indonesia, and one of them is the fertilizer subsidy to farmers Indonesia. Fertilizer itself is very useful to nourish the soil and provide vitamins to the plants, thus increasing the amount of production generated. Therefore it is necessary fertilizer for agriculture in Indonesia. CV. G company is one of the companies that produce fertilizer. Fertilizer produced by this company is an organic fertilizer and inorganic fertilizer. Problems faced by these companies are in planning the production of fertilizer produced. Companies want to optimize the amount of production of each fertilizer, maximize revenues, minimize production costs, and simultaneously optimize the working hours of employees. To meet these objectives, this research created program package using goal programming methods. Goal programming method can provide an effective solution / equilibrium toward the goals set, and the calculation will be assisted by using the Simplex method that has been modified. This method is an extension of linear programming, linear programming which can only solve problems with a single goal while the goal programming to solve problems with multiple objectives.

Abstract

Multivariate calibration model aims to predict the expensive measures obtained by using the measures of a cheap and easy. There are several problems that often occur in the model calibration, among others, and multikolinear. To overcome these problems we used partial least squares method (PLS). The study was conducted to apply the PLS method on the data gingerol. Based on research conducted with the two components of the model obtained with the diversity of variable Y at 83.8032% and the diversity of variable X equal to 100%, and obtained for R2 = 83.8% and RMSE = 0.100891 calibration data group and R2 = 84.2 % and RMSEP = 0.199939 for the validation data.

Abstract

Analysis of chemical substances in some processes an-organic bottled water and drinking water recharge has been done using One Way Manova. Samples originated from springs Ciburial Bogor taken in May 2009 at 10 depots refill drinking water process (AMDIU) Around Syahdan and Anggrek Campus of Bina Nusantara University. Reserve osmosis filtration processes and filtration Hollow Fiber and testing of heavy metal contents of five CN, Pb, Mn, Cr, and Cd in the company carried out the bottled water (bottled water) PT Buana Cikarang Tirta Abadi. Test results and analysis show that the processed water filtration contains CN, Pb, Mn, Cr, and Cd was lower than that of water filtration was not processed. And drinking water processed by filtration Reserve Osmosis, contains CN, Pb, Mn, Cr, and Cd was lower than that processed by Hollow Fiber Filtration and Granular Activated Charcoal.
