Abstract

Use of information systems at the university, which is the standard management of the university, is required to support all the activities of the academic community. Aside of determining the smooth operations, information technology also maintain the competitiveness of the competitors by constantly updating the information technology so as not to miss. Trends in the development of technology will make a strong connectivity between universities and stakeholders, governments, and partners. Some of the problems that occur when information systems are not yet fully integrated system, separate user management, application is implemented on different platforms and dashboards for management, not integrated. It is important for the university to provide Single and Integrated Application applications that are integrated into each of their services. Single and Integrated Applications are available at the web application / desktop / mobile multi-platform, for which data are available in real time, and there is no duplication of data occurs.

Abstract

Layanan teknologi informasi merupakan layanan bidang teknologi informasi yang selanjutnya dalam tulisan ini akan disebut dengan istilah layanan TI. Layanan TI memberikan dukungan untuk semua kegiatan operasional sebuah organisasi, termasuk Universitas Kristen yang memiliki sebuah bidang sistem dan teknologi informasi yang berada dibawah Direktorat Informasi. Bidang ini memerlukan sebuah pengelolaah yang baik dan telah mendefinisikan layanan TI sejak tahun 2014 kedalam bentuk Service Level Agreement (SLA). Namun sejak dibuat SLA tersebut belum pernah dilakukan analisis terhadap SLA yang ada. Oleh karenanya dilakukan analisis dari tahun 2016-2018. Penelitian ini bertujuan untuk menganalisis layanan TI dengan menggunakan sumber data utama SLA. Metode penelitian berupa observasi SLA dan dokumen mutu, wawancara dengan pihak terkait, menganalisis setiap layanan dengan beberapa alat yang sesuai, serta penyebaran survey kepada pengguna layanan. Hasil penelitian menunjukkan SLA telah dijalankan sesuai dengan taget namun setiap kegiatan layanan TI harus didukung sepenuhnya oleh dokumentasi lengkap agar pada saat pengukuran kinerja berikutnya dapat lebih menunjukkan pengukuran yang handal dan terpercaya.

Abstract

Almost all parts in an organization both commercial and non-commercial must have held an event. No exception in the education, especially at the University. The number of events carried out on campus is a phenomenon that makes students who are members of organizations learn to organize it so that it can run well. Organizing events is not easy and requires a lot of energy, time and costs starting from marketing, registering, ticketing, participant validation, and distribution of certificates. The aim of this research is to analyze the ineffectiveness and inefficiencies that occur in running an event. Analysis and observations were made based on the processes that took place in the holding of events held by students at Universitas Atma Jaya Yogyakarta. The process will be simplified by utilizing digital media so that the process of making an event becomes more effective and efficient. This research resulted in a BPR (Business Re-engineering Process) in which the marketing, registration, and ticketing processes that were originally done manually were, converted to digital with a web-based system. It is expected that from this BPR, researchers can develop an application to digitalize marketing, online event registration, ticketing, and event validation using QR Code. Keywords— event; marketing; promotion; QR code; registration

Abstract

Abstract — A loan is one of the most important products on the bank, which used for main revenue. All bank tries to find the most effective business strategy to persuade a customer to use the loan, but loan default has a negative effect after the application is approved. Loan default causes loss on the bank, therefore it is mandatory to calculate in order to decrease the risk of the loan default. This study uses random forest and adaptive boosting machine learning methods to get the prediction and decision. The random forest uses a voting method from many decision trees and adaptive boosting can support to increase accuracy, stability and handle an underfit or overfit problem. The experimental results show that Adaptive Boosted Random Forest outperformed normal random forest and Deep learning Neural Network (DNN) in recall rate evaluation metrics with small trade-offs in the accuracy. Keywords— Adaptive Boosting; Bank; Loan Default; Machine learning; Random Forest;

Abstract

This study discusses the analysis of year-on-year inflation data on the island of Sumatra using the Getis-Ord General G index and the Getis-Ord Gi* Index, which will be compared with the Bootstrap Method. And the Mann Withney Test for comparison of two time periods. The results showed that the highest average inflation was in Pangkal Pinang City by 5.82, and the lowest was in Banda Aceh City by 3.63. There is a significant difference in the median inflation rate from the cities of inflation on the island of Sumatra except in the cities of Banda Aceh, Palembang and Batam. With a significance level alpha = 5%, it is concluded that there are spatial cluster and spatial autocorrelation patterns in February 2014. Cities with high inflation value cluster with its neighbors are the city of Pangkal Pinang, and the low inflation value cluster is Banda Aceh. It means that a region is close to other regions has a similar level of inflation in terms of high and low at a certain time. In other words, commodities contributing to inflation between adjacent regions are interrelated. Keywords—Getis-Ord General G Index, Getis-Ord Gi* Indeks, Inflation, Spatial Autocorrelation, Spatial cluster.

Abstract

Poultry need food to maintain their lives and to produce. To meet the needs of these nutritional elements, poultry eat from various types of food. Because there is no single food ingredient that contains a complete nutritional element, so we need a variety of appropriate and balanced food ingredients to meet nutritional needs. This can be done by choosing cheap food ingredients without ignoring the quality of the nutritional content that is adjusted to the type and age of poultry. To solve the above problems, an expert system with a forward chaining method can be used to determine the nutritional needs and nutritional content of food ingredients, while linear programming with the simplex method is used to determine the combination of poultry feed-forming ingredients that meet economical poultry nutritional needs. The combination of the forward chaining method and the simplex method can accelerate the preparation of combinations of food ingredients, so that the resulting application can provide a solution in making decisions for the selection of food ingredients forming ration effectively

Abstract

One of the functions of the warehouse is to store finished products. Stored products will be grouped based on the same type of material or goods, with boxes that have been marked in color or other codes in accordance with the specified classification. In the warehousing system, vertical storage helps in maximizing the use of warehouse areas. Storage of goods that are still manual with the aid of a forklift also has a high risk of damage due to work equipment accidents. The application of automation technology to the warehousing system is needed because it allows the storage and retrieval of products to run more easily and regularly than done manually. This study aims to create an automatic multilevel storage system as a solution to improve work safety and facilitate workers in storing finished products. This system is made in the form of an elevator with a rack containing 12 cells. The elevator is driven by a stepper motor to move in the direction of the X, Y, and Z axis and is controlled through an Arduino Mega 2560 microcontroller. Object identification is carried out by the TCS 3200 color sensor and the infrared obstacle sensor to read the height of the object. In this study, prototype storage and lifter systems have been achieved as movers for storing boxes on shelves. The results showed success in shipping boxes according to the intended address, but there were still average error values on the x-axis motion of 0.125%, and on the z-axis of 0.11%.

Abstract

Abstract — Based on the prior study, some shrimp ponds went bankrupt due to pond water quality monitoring is still not good. Many shrimps get sick and die for water quality monitoring still relies on laboratory checks and is rarely done because of financial problems. The purpose of this study is to develop a monitoring system of shrimp pond water quality especially for vannamei shrimp using an Internet of Things (IoT)-based device with a data logging method. The system role is to monitor the water condition, record sensor data, and provide water quality status of shrimp ponds based on water movement, turbidity of water, and water temperature. The data logger device uses a microcontroller named NodeMCU ESP8266 and two sensors namely the LDR sensor and the water temperature sensor dallas 18b20. The devices are connected to the internet and send all water quality monitoring data to Google's database service called Firebase. The results of the water quality monitoring can be accessed through an Android-based monitoring application that is built using Flutter framework which contains information. Keywords— Flutter Android; Internet of Things; Monitoring System; Water Quality
