Abstract

The rapid development of Information Technology (IT) facilitates various fields, including the government sector. The application of IT in the government sector is carried out in the application of the smart city concept which consists of the application of 6 pillars. The application of the smart city concept in Malang City has been echoed since 2014 and is targeted for completion in 2022. Of the six pillars of smart city, smart governance is the pillar related to bureaucratic affairs. RW 12 Tulusrejo Village is one of the areas that requires the implementation of smart governance. RW 12 has 3 services, namely information services, finance, and letter submission. However, the implementation of these services is not optimal due to several obstacles. The first obstacle is that the data stored is still in the form of printed archives, making it difficult to provide data. The second obstacle is the pandemic situation in Indonesia which makes residents a bit afraid to meet in submitting letters. The third obstacle is the busyness of the RT and RW management which makes them not in place so that it hinders residents who want to submit letters. Therefore, a mobile application for the Rukun Warga community service was developed using the MASAM development method and the flutter framework. The results of the application design produce 16 use cases and the results of testing applications that are built on the usability side produce an SUS value of 70 for citizen applications and an SUS value of 68.5 for administrator applications.

Abstract

PT. Kencana Tiara Gemilang is a manufacturing company based on plastic sector and located in Singosari, Malang. PT. Kencana Tiara Gemilang products are geosynthetic, agricultural and innovation products. Problems that often occur in the production process are sales & marketing take a long time to receive some orders, PPIC makes the wrong calculations in determining raw materials, and the production process takes a long time because of Human Resources (HR). For this reason, it is necessary to evaluate the production process. After conducting interviews and observations, it can be seen that the production process is divided into three business processes, such as the production planning process, the production process, and the product evaluation process. The three business processes will be modeled by using the Business Process Model and Nation (BPMN) with a bizagi modeler as a tool. Furthermore, evaluation and analysis were carried out using the Failure Mode and Effect Analysis (FMEA) method to get the priority of the existing problems based on the RPN value. After that, the next step is to make recommendations for business process improvements using the Business Process Improvement (BPI) method with streaming tools. Finally, compare the results of the current business process simulation (AS-IS) and recommendations (TO-BE). The simulation comparison results show that there is a savings in the production planning business process of 21.55 % for Max Time and 5.01 % for Average Time, the production business process is 18.36 % for Max Time and 16.38 % for Average Time, and The product evaluation business process is 32.06 for Max Time and 42.48 % for average time. Savings indicates that the duration of time has decreased from the current ongoing business process (AS-IS) into a business process recommendation (TO-BE).

Abstract

Review on Google Play Store is one of the features used to provide a rating of an application. MyXL is a self-service application provided by PT XL Axiata Tbk on the Google Play Store that is useful for users to perform XL services easier such as activating internet packages, checking credit, checking remaining quota, etc. However, the review on the application is only in the form of text with no specific meaning and there are some high ratings but the reviews given are negative reviews, for that a sentiment analysis is needed that can classify reviews as user sentiment. In this research, the scraping stage was carried out for collecting application user review data, followed by the text preprocessing stage to process data by selecting data and turning it into more structured data. The data from the text preprocessing were word weighted using the Term Frequency - Inverse Document Frequency (TF-IDF) method. Then sentiment classification is carried out using the Support Vector Machine (SVM) algorithm. The best results were obtained with the SVM algorithm for sentiment testing for 2 classes using the value of training data and test data of 80%:20%, the total data is balanced with 160 positive and 160 negative data, experiments with cross validation K = 5 and the use of a linear kernel. The results obtained for the average value of 88% accuracy, 88% precision, 88% recall and 88% f-measure.

Abstract

Digital Wallet is an electronic application that can be used to make financial transactions online, without physical money and without cards, users only use smartphones in conducting financial transactions. A popular digital wallet application during this pandemic is Dana. The Dana app has many users, so there are often positive, negative and neutral reviews that are irrelevant to the rating given on the Google Play Store. The Dana application review data will be obtained using the Web Scraping technique using the Google-Play-Scraper API. The data from the scraping will then be done by text preprocessing to clean the text so that the data can be executed. Sentiment analysis can detect whether a text contains positive, negative or neutral opinions from user reviews that do not match the rating. Random Forest is a method in analysis that consists of several decision trees as a classifier. In this study, the random forest method was used by dividing three classes of sentiment, namely positive, negative and neutral. Also taking evaluation indicators, namely accuracy, recall, precision and f-measure. The test is carried out based on the number of trees and the depth of the tree to 1354 data by dividing the data by 250 data per class. Based on the results of tests and analyzes that have been carried out, with a comparison of training data and test data of 80%: 20%, namely precision 84%, recall 84%, F1-Score 84% and accuracy of 84% with a tree depth of 65 and a tree number of 400.
