Abstract

Credit union has a substantial role in supporting the growth of the national economy. A number of credit Unions implements DSS application to promote and accelerate the process of decision-making by management. DSS can provide ease of calculation, accuracy in the calculation and examination. However, an ITinvestment in DSS application, as well as other investments, is a segment that depletes costs and effort. The cost is calculated from the procurement, and continues during maintenance or during the investment implemented. Thus the implementation of DSS on a credit union needs to be measured whether it is quite fit and gives positive impacts on decision-making by management and on sale.

Abstract

PT Argatama Multy Agung is one provider of metal cutting services using turret machine. The quality of metal cutting services offered are still questioned. The quality service intended is that the length accuracy of the outcome product meets the requirements of the requested length. The purpose of this study is to determine what factors lead to defects the goods length, as well as to provide the right solution that factors can be eliminated so that the number of defective products can be reduced. In this research authors implement Six Sigma methodology with an improved model of Define-Measure-Analyze-Improve-Control (DMAIC) to perform improvement in the services quality provided by PT Argatama Multy Agung. On the improvement phase Design Of Experiment (DOE) is used to find the machine configuration that can produce the best quality. From the research conducted, a significant increase of sigma is obtained.

Abstract

Changes in land use due to the rapid growth of building construction leads to an increase in direct runoff, as well as declining water that seeped into the ground. Consequently, water distribution happens to be unequal of between the rainy and dry seasons. This phenomenon also occurs in the area of Kijang Campus - Bina Nusantara University which always comes up with puddles even though the rain falls with only a short duration. In this research the rainfall on the Kijang Campus - Bina Nusantara University is assessed based on the rainfall data record to obtain the rainfall intensity of various periods. Field survey is conducted to determine the existing infiltration capacity (with / without bio pore holes) and on-site. It is concluded based on the research results using Horton method that the soil on the Kijang Campus - Bina Nusantara University is earth embankment that has the infiltration capacity ranging between 0.0867 - 0.2165 m3/hr. This illustrates that the soil infiltration capacity is relatively small and thus requires the installation of bio pore holes with distance by 0.5 meters.

Abstract

This paper discusses the design of computer programs that is able to discern the characteristics description of water surface elevation data in Manggarai water gate, which variable is the most influential on the water surface elevation model and find a proper flood forecasting model using multivariate autoregressive model. The result of this study is able to assist the water gate officer in delivering early warning, prevention and anticipation of flood countermeasure. The forecast equation model obtained is Yt = 109,.7828 + 0,9291 CHt-6 – 24,484 T t-2 – 0,06245 PM t-2 + 1,4706 KB t-2 in which temperature and water surface elevation is a variable that owns the strongest correlation. This variable owns negative correlation which means that if the temperature falls, the water levels will rise. The coefficient of determination has a value of R2 = 0.4056 and the Durbin Watson statistics for DW = 0.7429.

Abstract

Cities in Indonesia has the same problem in the presence of slum residential in some area. The existence keeps growing altogether with the increasing of population and urbanisation in some cities. Slum residential brings several bad effects towards urban life, not only based on physical performance but also affects the decreasing in human resource quality especially those who live in the area. Along with the city development, slum residential should be arranged into a livable environment; which could be handled by area-based that placed the slum area arranged altogether by supervising surrounded environment like a united area.

Abstract

Sorting is a basic algorithm studied by students of computer science major. Sorting algorithm is the basis of other algorithms such as searching algorithm, pattern matching algorithm. Bubble sort is a popular basic sorting algorithm due to its easiness to be implemented. Besides bubble sort, there is insertion sort. It is lesspopular than bubble sort because it has more difficult algorithm. This paper discusses about process time between insertion sort and bubble sort with two kinds of data. First is randomized data, and the second is data of descending list. Comparison of process time has been done in two kinds of programming language that is C programming language and FORTRAN programming language. The result shows that bubble sort needs more time than insertion sort does.

Abstract

This research is based on the rapid development of the culinary and information technology. The difficulties in communicating with the culinary expert and on recipe documentation make a proper support for media very important. Therefore, a web-based database application for the public is important to help the culinary community in communication, searching and recipe management. The aim of the research was to design a web-based database application that could be used as social media for the culinary community. This research used literature review, user interviews, and questionnaires. Moreover, the database system development life cycle was used as a guide for designing a database especially for conceptual database design, logical database design, and physical design database. Web-based application design used eight golden rules for user interface design. The result of this research is the availability of a web-based database application that can fulfill the needs of users in the culinary field related to communication and recipe management.
