Abstract

ABSTRACT The limitations of conventional architectural visualization methods, which only provide a 70% level of understanding, and the gap in the integration of Aug mented Reality (AR) technology with the Internet of Things (IoT) are major challenges in the modern architectural design industry. This research aims to develop an AR application integrated with an IoT system for architectural de sign visualization and smart home device control using a mixed-method approach with the ADDIE development model. The developed system uses Unity 3D as the AR rendering engine, Vuforia SDK for marker detection, NodeMCU ESP8266 integrated with a DHT22 sensor for temperature monitoring, and a relay system for lighting control through the Blynk platform. The testing was conducted on 68 respondents using the System Usability Scale (SUS) instrument, marker de tection accuracy testing, and system latency evaluation. The results showed that the SUS score reached 80.96 (category “Good”), exceeding the minimum target of 70 by a margin of 15.7%. Vuforia marker detection accuracy reached 92% under various lighting conditions, exceeding the 80% target with a very strong correlation (R=0.994). User understanding of the architectural design increased significantly to 85.7% compared to the conventional method, which was only 70% (p<0.05). The real-time temperature monitoring system using the DHT22 sensor achieved an accuracy of ±1°C with updates every 5 seconds, in line with the research target. Although the IoT control latency reached 4000ms, exceeding the target of 1000ms, the system still provided an acceptable interaction experience in the context of a smart home application. This research successfully bridges the gap between AR and IoT technologies within an integrated platform, making a significant contribution to the digital transformation of the architecture industry and the development of a more efficient and interactive smart building ecosystem.

Abstract

Sentiment analysis is critical to understanding how an app, such as a digital training app like Digitalent, is viewed by users. User reviews available on app distribution platforms provide ample data for this analysis. However, in sentiment analysis, data imbalance is a common problem; positive reviews tend to outnumber negative and neutral reviews. This imbalance can impact machine learning models, which can lead to inaccurate predictions of the majority class. The purpose of this research is to solve this problem by using SMOTE (Synthetic Minority Selection Technique) technique in sentiment analysis of Digitalent app reviews and comparing the performance of two machine learning algorithms, Naive Bayes and Random Forest. The research data was collected from Indonesian user reviews from the Digitalent platform. Before being processed for analysis, the data went through pre-processing processes such as cleaning, tokenization, and normalization. SMOTE technique was applied to balance the number of reviews for each sentiment class. Furthermore, Naive Bayes and Random Forest algorithms are used to categorize the sentiment. The results of the SMOTE application research successfully increased the proportion of negative and neutral classes, so that the distribution of the dataset became balanced. The test results show that the accuracy of Naïve Bayes increased from 68.25% to 92.16%, while Random Forest increased from 68.25% to 92.16%.Keywords: K-Means Clustering, education level, clustering, village education, RapidMiner

Abstract

The digital era has transformed lifestyles, with people increasingly relying on electronic devices as tools for everyday life. Technology simplifies various activities by streamlining data and information processing. The growing demand for data has driven the development of new technologies to process information quickly. Technological advancements have improved transportation, access to information, education, and the convenience of online transactions, particularly through digital wallets or e-wallets. Digital financial services, including e-wallets, facilitate easy transactions using e-wallet funds. The primary reason for their use is the convenience of electronic wallets, which eliminate the need for cash and simplify transactions for both buyers and sellers. The case of i.Saku demonstrates its popularity, with over 5 million downloads on the Google Play Store since 2017. Google's digital platform, Google Play Store, includes user reviews as a valid source of information. Nearly 50% of internet users rely on recommendations from other users before using a product. Google Play Store reviews influence the decisions of potential users, but managing them manually is not easy. Sentiment analysis, or opinion mining, is the study of opinions, behaviors, and feelings of individuals towards an entity and is crucial for understanding user reviews. In the context of i.Saku, this research focuses on sentiment analysis of Google Play Store reviews using support vector machine techniques. The study outlines the stages from preprocessing to sentiment analysis, highlighting the complexity and benefits of technology-based sentiment analysis.
