Abstract

This study focuses on optimizing the management system of tourism villages in Indonesia through the development of a contextual and relevant information system that caters to users' needs. Specifically, the study targets the Morotai Island Regency, where the tourism village management requires a website-based system capable of providing comprehensive information on attractions, accessibility, accommodation, and ancillary services to a broader market. The study uses the Software Development Life Cycle (SDLC) with a Waterfall approach to design the system, with a focus on the actors involved in the system, including tourists and prospective tourists (users as tourists), administrators and community members (users as a community), and stakeholders such as entrepreneurs and formal organizations supporting tourism (users as stakeholders). The resulting system, SIDEWITA, is expected to optimize the management of tourist villages in Morotai Island Regency. However, the study is limited to the design phase using the Waterfall approach.

Abstract

This study aims to design a marketing website for special interest tourism destinations in North Halmahera Regency. The method used is design thinking. The design thinking method has five stages: empathize, define, ideate, prototype, and test. At the empathize stage, the needs of system users are classified based on the characteristics of the user as a host or guest. In the define stage, the problem statement technique is used to define the problems and needs of users into four parts: lack of awareness and exposure, limited digital infrastructure, the limited availability of tourism-related infrastructure, and the lack of tourism-related data. At the ideation stage, the main problem identified related to the marketing of special interest tourist destinations is the lack of tourism-related data, so the idea to solve the problem is through the design of a website that accommodates all information about destinations and events, hotel accommodation services, resorts and cottages, vehicle rental services, and travel experiences to North Halmahera which are shared in the form of articles to short videos. At the prototype stage, the database and interface design are designed according to the analysis results at the empathize, define, and ideate stages. Furthermore, at the testing stage, aspirations about prototypes are carried out through posters and short videos to gain insight into the subsequent development. Thus, marketing special interest tourist destinations becomes more effective and efficient using a website-based digital platform.

Abstract

E-learning UAJ is a system provided by Unika Atma Jaya to facilitate the learning process for both students and lecturers. However, this system is still rarely used, especially among engineering faculties. This forms the basis for conducting the following analysis. The purpose of this research is to measure the level of usability of the UAJ e-learning system. Usability analysis is carried out using five components of usability outlined by Jakob Nielsen: Learnability, Efficiency, Memorability, Errors, and Satisfaction. The indicators within these five components are then compiled into a questionnaire, which will be distributed to active lecturers and students across all faculties who utilize the UAJ e-learning platform. This study employs a Likert scale with five categories, ranging from category 1 indicating "very bad" to category 5 indicating "very good." Among the five usability criteria assessed for both students and lecturers, the majority of responses fell within category 3, indicating sufficiency. The average scores ranged from 14.122 to 18.731 for lecturers and from 19.825 to 21.845 for students. Overall, the usability level of the UAJ e-learning platform is deemed satisfactory, enabling more effective utilization by both lecturers and students. Additionally, the study results propose several solutions for enhancing the development of the UAJ e-learning system.

Abstract

As an agency, it is necessary to evaluate and assign value to the content outcomes that have been published by content creators periodically. Aurora News Agency, which is one of the content creator agencies for Snack Video, has over 700 member content creators. This requires specialized techniques to facilitate and expedite the assessment of the performance of these content creators. Therefore, research was conducted on a decision support system using the TOPSIS method as a decision-making tool for evaluating the best content creators within the agency. Data was collected from a total of 630 content creators, and after undergoing data cleansing processes, a total of 10,916 content items were obtained. The research results present a ranking of the top 10 content creators based on their preference scores, ranging from the highest to the lowest. Anemz Tv is the content creator with the highest preference score of 0.4368, securing the first rank. On the other hand, Talenta.TV is the content creator with a preference score of 0.3203, earning the second rank. Upon analysis, differences in strategies for each content creator became apparent, with some focusing on quantity and others placing emphasis on the quality of content. In conclusion, the application of the TOPSIS method can be implemented relatively simply, with sufficiently fast computations, and it yields a diverse range of preference scores

Abstract

The increasing trend and public interest in coffee shops, also known as cafes. One of the cafes named Kopi KurangLebih has great potential to attract customers due to its strategic location, high-quality menu, and aesthetic ambiance. Although Kopi KurangLebih already has an Instagram account to showcase its content and engage with followers, the information provided is limited and lacks proper organization. Visitors to the coffee shop struggle to make menu choices due to the absence of a platform to display the available options. To address these challenges and improve the quality of service, a website is needed to document and present information that assists customers in making menu selections. The current reliance on social media as a source of information for coffee shops is inefficient and temporary, as the information shared only appears briefly on users' timelines. Hence, the development of an attractive and informative website for Kopi KurangLebih becomes necessary. The website should be designed according to user needs and the resources available to Kopi KurangLebih. By utilizing a digital information medium in the form of a website, potential customers can access and obtain information easily, thereby increasing their interest and purchasing power. The research also applies the Three Circles method and incorporates various UX Law principles into the user interface (UI) design. Through observations and analysis, the research identifies the values of Kopi KurangLebih, customer needs, and competitor values. This research successfully built a UI prototype of the KURLEB website, transforming it into an effective digital platform for promoting, storing, and providing information about Kopi KurangLebih. It also achieved a good user experience by providing relevant information, intuitive navigation, and appealing visual aesthetics. With a well-designed UI and the applied principles of UX Law, this website delivers a positive user experience, enhances customer engagement, and contributes to the sustainable marketing of Kopi KurangLebih as a local coffee shop brand.

Abstract

In general, the buyers of rice field produce are often middlemen who offer the lowest possible prices to the farmers. This is due to the lengthy distribution chain that causes a significant price difference between the low prices paid to farmers for their rice and the high prices consumers pay for milled rice. Therefore, in an effort to cut out the distribution chain that disadvantages both farmers and consumers, the idea of developing the Petani Sawah Sugita mobile-based application emerged. This application enables farmers to sell their rice and milled rice directly to consumers at prices that benefit both parties. The research was conducted by applying the four main stages of the SDLC. The requirements analysis phase involved observations and direct interviews with farmers in one of the rice fields located in the Ciasuk area, Tangerang Regency, Banten. The design phase was carried out by creating UML diagrams. The implementation phase was done with the assistance of Android Studio, resulting in the Sugita Rice Field Farmer mobile application. The application's standout feature is the location search for farmers or nearest products from users, built using the Dijkstra algorithm. The system testing phase was performed using black box testing. The test results showed that 105 out of 114 test cases, or 92.1%, met the expected outcomes. In conclusion, the development of the Sugita Rice Field Farmer application proceeded well and was successfully implemented. This application can help reduce product delivery costs and foster relationships between users and farmers. Furthermore, it simplifies the process for farmers to market their agricultural products to the wider community and provides valuable experience for farmers to stay up-to-date and leverage existing technology advancements.

Abstract

The graduation rate of students is an important measure of a school’s success, as it indicates the school’s ability to help students complete their education. Predicting student completion is crucial for schools to identify at-risk students and offer them early interventions to improve their academic performance. This can also assist policymakers in developing effective policies and programs to enhance graduation rates and reduce dropout rates. The dataset used in this study was obtained from the Kaggle website, and the best model proposed utilizes the Random Forest method with hyperparameter tuning. By adjusting the n_estimator parameter to 1000, our proposed method decreases the mean squared error (MSE) value from 0.5525155 to 0.5374983 and increases the R2 Score value from 0.9984039 to 0.9984873. The study also compares the performance of the proposed model with other datasets sourced from the University of California Irvine (UCI), demonstrating superior performance across all experiments. The results consistently show a decreasing trend in MSE value and an increasing trend in R2 value for all datasets

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.
