Abstract

Nowadays, many companies often offer a discount to customer. The goal is that the company can attract new customers. However, the offer given cannot be done randomly. Offers must be directed to the right customers so the company doesn’t need to spend much money. This study will analyze to determine whether there is an influence of the association rule on customer retention. The data used is the Acquire Valued Shopper Challenge taken from the Kaggle website. As the program used is java with the Hadoop framework that uses the association rule method. Tests carried out twice using different data. The objective to be achieved from testing is that the model created can predict customers who will retain if they get an offer. With the tests carried out, the best results to answer the objective is to use data in the second experiment with the ratio of training data to testing data is 7: 3 and gamma 0.1 with accuracy obtained is 58.21%.

Abstract

Management Information System has become one of the mediaused to facilitate the administration, storing and viewing dataquickly and easily through Web. Nowadays, manualadministration requires more and less efficient resources,causing human error to affect important data.To answer the issue, a management information system is neededby utilizing website-based technology , assisted by AcceleratedMobile pages on the main page .By utilizing this technology, awebsite can be easily opened even in a slow internet connection.In addition, the presence of the website as a media managementinformation system facilitates the management of data, theadministration process of all parties in need in the languagecourse.From the research and testing systems that have been made, theapplication can help facilitate the process of administration anddata management. From the results of the questionnaireconducted on 10 respondents, the level of satisfaction with theprogram reached 3.1 on a scale of 4.

Abstract

Plastic bottles and cans are anorganic waste that cannot be decomposed by bacteria naturally and take a long time decomposed. Until now, people awareness to care about the environment is still low. Even though waste sorting is very important before the waste recycling process. According to Kediri City Environment, Hygiene and Gardening Agency, waste such as plastic and cans require special treatment for the recycling process. Until now, the process of sorting waste is still done manually by humans. This process require a lot of energy, a long time and still cannot overcome the amount of the waste nowadays.This research uses Convolutional Neural Network (CNN) method for object recognition. There have been other research about the classification of plastic waste. Both of studies only use plastic waste as the object. There is no studies yet about cans waste. Therefore, this research will carried out an introduction to plastic bottles and cans waste.Based on the result of the study, the activation function that suits the case is ELU. While using four convolutional layers, four max pooling layers, and three fully connected layers in total. This study uses 0.00001 for the learning rate, 0.8 for the dropout rate, and 50 times epoch. The result from test that were done by using this CNN model architecture is an accuracy rate of 86%.

Abstract

In scraping a website, the main concern is the type of website whether it is a static or dynamic website, and also the data structure of the website. With different website characteristics and diverse web scraping tools, it will make users quite difficult in choosing tools that suit their needs. The purpose of this research is to compare web scraping tools from different website characteristics, and to provide recommendations for web scraping tools for future research by knowing the right tools in handling each website's characteristics. Based on the results of tests that have been done, it can be concluded which tools are more effective and efficient in certain conditions.

Abstract

For years, TK Anak Ceria does not have a centralized and organized academic information system. The data is being kept in archives and this situation complicates the school to control the school’s work and quality, such as student’s grades data that are still kept in paper archives, unstructured student’s data, manually written cash flow transaction and others.Based on that problems, the solution is to make a design and implementation of web based school administration information system on TK Anak Ceria. The system will facilitate the arrangement and data storage for the school administration data, and the school’s finance. This administration information constructed using SQL Server 2005 and Visual Studio 2005.From the implementation and application setting, it can be concluded that the system is useful enough to be used as school administration information system. However, it also can be concluded that there is a lack of interface design in the report forms.

Abstract

On March 2, 2020, President Joko Widodo's announcement regarding the COVID-19 virus has made its way to all of Indonesia, serving as a warning to the people. The virus continues to grow and spread its influence across cities, one of which is Surabaya. Surabaya attained the 'crimson zone' status on 2nd of June, 2020 due to the drastic increase of positive COVID-19 cases which tallies to 2748 people. The rapid pace at which COVID-19 spreads results in a high death rate.This research was done to try and prevent high casualty rates by predicting the need for health equipment, isolation rooms, medical personnel, and the need for personal protective equipment (PPE) for COVID-19 patients. There were two methods used for the sake of predicting, namely the Artificial Neural Network (ANN) and Susceptible Infectious Recovered Decease (SIRD) methods. The methods in question will have their accuracies tested using error measurement methods which include the Mean Absolute Deviation (MAD), Mean Square Error (MSE), and Mean Absolute Percentage Error (MAPE). After measurements have been made, the prediction results from these 2 methods will be utilized to calculate the needs for equipment, isolation rooms, medical personnel, and PPE needs based on the regulatory patterns owned by the S, N, and X hospitals. Based on the results of the website implementation analysis, the ANN method is shown to have average error rates of 53.1733 for training and 89.73 for testing based on the MAD method, 6581.09 for training and 22953.9067 for testing based on the MSE method, and 17.7367% for training and 16.3067% for testing based on the MAPE method. The SIRD method is shown to have average error rates of 309.81, 150496.08, and 30.2% for the MAD, MSE, and MAPE methods respectively.
