Abstract

This research employs the CRISP-DM framework to analyze sentiment and toxicity dynamics in tourist vlog reviews thoroughly. The study delves into sentiment classification and toxicity identification nuances by leveraging machine learning algorithms such as k-NN, SVM, NBC, and DT with SMOTE. Utilizing a dataset comprising a substantial number of posts, the analysis reveals varying levels of accuracy across different algorithms. For instance, k-NN and SVM showcase promising accuracy rates of 85.90% and 86.27% in sentiment classification, while NBC and DT with SMOTE yield 72.52% and 71.14%, respectively. Furthermore, the research elucidates the limitations of toxicity analysis, with NBC demonstrating a precision of 64.96% and DT exhibiting lower recall rates. These findings highlight the importance of robust methodologies for understanding sentiment and toxicity dynamics in online content, particularly in tourist vlog reviews.

Abstract

To achieve sustainable tourism, a monitoring system of tourism activities is needed to minimize the environmental impact of the intensity of tourist visit activities. The development of coastal tourism needs particular attention, considering the diversity of activities around the coast related to environmental sustainability, including coral reefs. This study designed an information system and database to monitor coastal tourism activities to minimize the risk of damage to the coastal environment due to tourism activities. The method used in system design is Rapid Application Development (RAD), which has the following stages: requirement planning, user design, construction, and cutover. Meanwhile, the system and database design context is adjusted to the tourist destinations of Luari Beach, North Halmahera Regency, North Maluku Province, Indonesia. The results of this study show that identifying user needs at the requirements planning stage shows the need for a database of tourists visiting the destination and data related to the vehicles used. There is a need for a database related to beach conditions or beach environments and data on people involved as small entrepreneurs around coastal tourist areas. Considering the user's needs, at the user design stage, a prototype design is carried out using Oracle Apex with a dashboard display according to the data needed. At the construction stage, database configuration is carried out to display data visualization so that managers of beach tourist destinations understand the context and priority. System features and functions are tested at the cutover stage to evaluate application performance. The cutover result shows that successful applications can be used in decision-making. Thus, tourism destination managers take infrastructure development policies following existing conditions and short-, medium-, and long-term development plans.

Abstract

One of the challenges of tourism development in North Halmahera Regency is integrating technology in decision-making to determine leading and priority tourist destinations. Thematically, the ecology-based tourism development approach is the concept of ecotourism that balances environmental sustainability with tourism economic growth; however, tourism databases and information systems need to be developed by considering economic, socio-cultural, and environmental distribution and growth. This research adopts the Rapid Application Development (RAD) method in designing the Community-based Ecotourism Monitoring System. The stages in the RAD method consist of requirements planning, user interface design, construction, and cutover stages. At the requirement planning stage, this system will accommodate three main aspects: local attraction, local transportation, and local accommodation. A local attraction focuses on ecotourism development approaches, while local transportation refers to local transportation services managed individually or community-based. In addition, local accommodation refers to the business of homestay accommodation services as a form of community participation in tourism activities. At the construction stage, the instrument used in designing this system database is oracle-apex, which utilizes map, classic report, and form (modal dialog) features. Features and functions are tested at the cutover stage, and access rights restrictions are provided based on administrator, user, and viewer roles. The system design results show that policymakers must support community involvement in each tourist destination in determining priority areas for ecotourism infrastructure development. The testing result shows that all the features and operators are thriving and ready to be used. Thus, implementing RAD in the design of a community-based ecotourism monitoring system can be adapted to the context of ecotourism in North Halmahera Regency, North Maluku Province, Indonesia.

Abstract

Technological developments have sparked creativity through innovation in tourism marketing strategies through various video content. There have not been many studies that use video statistical data as a reference to create other creative content and identify opportunities to increase viewers and subscribers to access a broader range of system users. This research offers ideas for designing Tourism and Travel Vlog Content Statistical Analysis using the Rapid Application Development (RAD) approach. The stages in the RAD method consist of the requirements planning stage, user design stage, construction stage, and cutover stage. This study's results show that user needs identification shows the need for Author Channel data, statistics, and relation patterns that can be used in Social Network Analysis (SNA). At the user design stage, the dashboard design creates a page where images or background videos are taken in content to SNA and Chain Network pages. In the construction stage, design is carried out according to the use case diagram to manage data and make data as helpful information in identifying publication opportunities so that the video rating made is by tourist preferences so that it can trigger intentions to visit tourist sites. At the cutover stage, testing the features and functions of the application is carried out; the test results show that all pages can be accessed without any problems. Thus, this application can analyze statistical data of content published on various platforms. This application generally benefits content creators who consider statistical information in addition to popular content design.

Abstract

The quality of education needs to be observed and maintained in building an effective teaching and learning environment. There are several factors that can affect the quality of education in a school, such as the availability of human resources, supportive learning facilities, environmental conditions, and various other factors. The focus of this research is on the ideal number of teachers in a school, considering the number of students and the availability of facilities such as laboratories and libraries, which will be correlated with the failure to pass the class rate. Data were obtained from the official website of the Kemdikbudristek regarding educational statistics, comprising 29 districts in Tangerang Regency for the academic year 2023/2024 at the senior high school level. The analysis was conducted using multiple linear regression, and it was found that the variables "availability of laboratory" and "availability of library" did not correlate with the failure to pass the class rate, whereas the "teacher ratio" variable correlated with the failure to pass the class rate with a value of +0.46. This can be explained that for every increase of 1 unit in the teacher ratio variable, or in other words, the fewer teachers teaching in a school compared to the number of students, the failure to pass the class rate will also increase by 0.46 students. Therefore, the results of this research can provide input for schools, especially in Tangerang Regency, to pay attention to the number of teachers in each school.
