Abstract

In 2017, the minister of Indonesia tourism stated that everyone who travels spends his time for culinary about 30-40%. The key point in increasing the tourism income; especially from the culinary sector is about how to inform and promote the wealth of Indonesia culinary to all travellers. The information system of Bengkulu tourism has been developed in the previous study. However, that system has not been able to provide the best culinary recommendations to the travellers. This study focuses on designing and implementing the recommendation system of Bengkulu culinary by using sentiment analysis and simple adaptive weighting (SAW). The recommendation offered is based on the user review and criteria as well. The user review will be classified into positive, negativeand neutral reviews by the sentiment analysis method. If the user needs culinary information based on criteria, the system will provide a recommendation and rank of culinary by using simple adaptive weighting. These criteria used are the average price,opening hours, facilities, distance from a central city, and transportation as well. Sentiment analysis method obtains the accuracy of recomendation classification at 79% while the recommendation rank obtained by the SAW method is 90.83%. These results show that the proposed method has a potential for assisting the travellers to gain the best culinary recommendation, especially in the Bengkulu area.

Abstract

Advances in information technology in the banking sector have led banking institutions to continuously innovate and improve their services. One such service is the emergence of mobile-based banking applications. Bank Bengkulu has introduced a mobile-based banking application, but it has received poor ratings and negative feedback from its users. This study aims to evaluate user satisfaction with the Bengkulu mobile banking application using the End User Computing Satisfaction (EUCS) method, then improve user satisfaction by redesigning the application using the Double Diamond method, and re-evaluate the results of the application redesign using the System Usability Scale (SUS) method and sentiment analysis using Natural Language Processing (NLP) with the IndoBERT model. The results show that user satisfaction with the Bengkulu mobile banking application was 2.77 when measured using the EUCS method. This measurement falls into the ‘adequate’ category but is very close to the ‘dissatisfied’ category. After the application redesign, user satisfaction improved, as indicated by the evaluation of users using the SUS method with a score of 87.975, which falls into the ‘excellent’ category. The results of qualitative user satisfaction measured using sentiment analysis methods show that there were 75 positive sentiments, 22 neutral sentiments, and only 3 negative comments. The results of the study show that there was a notable improvement in user satisfaction after the Bengkulu Bank application was redesigned.
