Abstract

The library is a collection place of various kinds of books. Arrangement of books by category called book shelving makes easier for customers to choose and find books. However, the location and arrangement of book categories becomes a problem in a library. Based on the book borrowing data, data mining was carried out to find out a book borrowed simultaneously by library visitor in one transaction. This can be solved by using the association rule technique and a priori algorithm. Possible combinations of borrowed books were based on certain rules and then tested whether the combination of items meets the minimum support requirements to create eligible rules. The results of this study were in the form of information about a combination of borrowed books for libraries to arrange the location of books according to categories that are often borrowed together.

Abstract

The Bottled Drinking Water Industry has grown rapidly to various provinces and cities throughout Indonesia now. The development of this industry is caused by high demand from consumers and the lower quality of raw water in springs and wells. PT. Cahaya Bumi Intanpari (CBI) is a company that produces gallons, bottles, and glasses bottled drinking water under the brand “AirMu”. Sales of bottled water every month always fluctuate, the management of PT. Cahaya Bumi Intanpari requires an estimate of the amount of production of each type of bottled water to market demand in the future. Based on the description of the background, in this study, a desktop-based application was designed and built. The research method used includes data collection and data analysis. Data collection includes observation, interviews, and literature study. While data analysis includes making data flow diagrams. The forecasting model is used in forecasting the sales of bottled drinking water at PT. Cahaya Bumi Intanpari is a time series or it can be called a time series, and the forecasting method used is single exponential smoothing. From the results of calculation testing, it is proven that the Single Exponential Smoothing method can be implemented in the AMDK sales forecasting system. Based on the validity test, it is found that the prediction test results of bottled drinking water sales below 20% are included in the good criteria.

Abstract

The level of security in Central Java declined but for each region is not the case. Based on the crime index and the number of security posts in each police region of Central Java.These data are used for grouping the two regions in Central Java, namely good security level and bad security level.K-Means clustering method is a method used to classify data based on multiple attributes.K-Means clustering method is a method used to classify data based on multiple attributes. In this study, will be applied to the K-Means method with random initial centers. It is derived from two police regions that describe the good and bad security level.The formulation of the problem is to know the areas with good and bad security level in Central Java. Based on the results, there are 8areas with good security level and 27 areas with bad security level. Keyword :Crime Index, K-Means Clustering

Abstract

Forecasting is an attempt to predict future conditions through testing conditions in the past using previous data. According to the data obtained from Dinas Perdagangan, Koperasi, dan UMKM Sukoharjo in January 2016 - August 2019, the prices of rice in Sukoharjo Regency experienced instability. Based on this problem, a method is needed to predict the price of rice in Sukoharjo Regency to prevent price volatility and to provide an overview of the price of rice in Sukoharjo Regency in the coming period. The method used in this research is the Exponential Smoothing Winters method. The rice price prediction application is made using the vb.net programming language and the sql server database. in this application produces predictive calculations for rice and in it there are graphs and reports on the results of prediction calculations. This study resulted in an overall MAPE of 3.91% for the price of  premium IR 64  rice,  and  4.24% for the price of  medium IR 64 rice.

Abstract

One of the key public health service facilities is Public Health Center (Puskesmas). For new residents, it is very important to have information about the location of the puskesmas or hospital as well as information about the shortest path to the puskesmas or hospital. The size of the region and the volume of traffic present a challenge for people who are unfamiliar with the Karanganyar Regency's routes. The aim of this research is to enable the community to easily locate the health center and to provide access for numerous individuals who require assistance in locating the health center in Karanganyar Regency. Floyd-Warshall research methodology was used in this study to create this system while data collection from Karanganyar District Health Office is then required in this study. The results of this study are in the form of the closest route that is connected to Google Maps, which is information about the location of the health center in Karanganyar Regency which is beneficial for people outside Karanganyar Regency. This study's test findings, which used Floyd Warshall's results approach, further ensure its success in identifying the closest path. The test scenario and the available observations matched 91.6% of the 12 test components, according to the system functionality test. Based on the validity test, it has an average error in predicting the distance from the starting point to the search location of 98%.
