Abstract

Nglurah Village, Tawangmangu, still faces challenges in effective tourism promotion due to the use of conventional promotional methods. This study employs a mixed-method approach to identify the issues and expectations of tourism managers. The results indicate that 50% of managers struggle with tourism promotion, and 70% believe that the implementation of technology is crucial to promote the village's tourism potential in an attractive and interactive way. This research aims to combine image stitching and seam carving methods to enhance the quality and diversity of responsive virtual tour applications. Image stitching is the process of merging multiple 360° panoramic images into a single comprehensive image that accurately represents the actual scene. Meanwhile, seam carving is a technique for carefully cropping an image to remove less important parts while preserving important areas when the image is resized. The collaboration of these two methods is expected to produce virtual tour applications that can adapt to the shape and size of gadgets without losing important content. This virtual tour application is expected to enhance the user experience in virtual tourism and open up opportunities for technology-based tourism development in Tawangmangu Village. Additionally, this research can increase the attractiveness of Tawangmangu Village tourism and provide a foundation for further research in virtual tour development.

Abstract

Waste management poses a significant challenge in many regions, including Indonesia. This study aims to analyze and evaluate the performance of Resik Kutho Waste Bank in Surakarta City, focusing on effective and sustainable waste management strategies. A qualitative research method was employed, combining SWOT analysis and primary data from observations, interviews, and questionnaires distributed to waste bank managers and customers. The results show that Resik Kutho Waste Bank has internal strengths that can be leveraged for the development of more efficient waste management strategies, particularly in seizing existing opportunities. However, certain aspects such as financing and operational techniques need improvement. This study provides valuable insights for waste management at the community level, emphasizing the importance of integrating the waste bank's internal strengths with existing opportunities to achieve more sustainable waste management.

Abstract

The aim of this study is to examine how geographical location affects the credit risk faced by savings and loan cooperatives. Using a quantitative approach, this research will develop a credit risk model that considers geographical variables,measured by the Human Development Index (HDI). The initial stage of the research involves classifying the credit dataset according to the categoriesdetermined by Bank Indonesia. The data cleansing process resulted in attributes such as credit ceiling, HDI, and credit category. Analysis was conducted using Chi-Square, and Logistic Regression methods. The Chi-Square analysis results showed  statistically significant relationship between credit ceiling, HDI, and credit category (p-value < 0.05). The Logistic Regression models demonstrated high accuracy in classifying the data, with Logistic Regression achieving 89.71%. In conclusion, credit ceiling and HDI have a significant influence on credit category, with the Logistic Regression model data classification. This study provides valuableinsights into how credit ceiling and HDI influence credit categories, which can be used to make better decisions related to public policy, developmentplanning, and social interventions

Abstract

Penelitian ini mengevaluasi pengalaman pengguna (user experience) aplikasi Virtual Tour Reality (VTR) dalam konteks wisata menggunakan System Usability Scale (SUS) untuk kegunaan dan End-User Computing Satisfaction (EUCS) untuk kepuasan. Studi ini melibatkan 293 responden, terdiri dari ahli IT, pengelola objek wisata, dan masyarakat. Hasilnya menunjukkan bahwa aplikasi VTR dinilai "puas" dari aspek Learnability, Efficiency, Memorability, Error, dan Pleasantness, dengan nilai terendah pada Error (3,75). Kepuasan pengguna juga dinilai "Puas," dengan nilai terendah pada Timeliness (3,92). Kedua skor berada di atas 3,75, menempatkan kepuasan pengguna pada level 4, yaitu "Puas." Studi ini juga menemukan hubungan korelasi positif yang sangat kuat antara usability dan kepuasan pengguna, di mana peningkatan kegunaan meningkatkan kepuasan. Meskipun aplikasi VTR memenuhi ekspektasi, peningkatan pada aspek Error dan Timeliness disarankan untuk mencapai tingkat "Sangat Puas."

Abstract

The current learning process requires students to be active, creative, and innovative both in activities and lectures. Students are one of the main indicators in the accreditation of a university. Therefore, a tertiary institution is also required to be able to receive and provide assistance to students and graduates in the form of scholarships, such as achievement scholarships. At present, it is quite difficult to determine students who have excelled at tertiary institutions in considering and determining students who are entitled and appropriate to receive them. The Decision Support System is a solution to be able to assist in managing student achievement data and determining the right scholarship recipients, and is supported by blockchain technology so that security is guaranteed and protected so that it is not easily hacked and information can be tracked by parties who are given access, so that they can share information transparently. This study uses the waterfall system development method with the Analytcal Hierarchy Process (AHP) problem solving method for the analysis model of the decision support system , blockchain algorithms, and open source software used solidity ethreum. The actual results will be that a decision support system with the AHP model combined with Blockchain can help provide more precise decisions to determine more appropriate scholarship recipient students, as well as increase trust in parties in tracking every transaction information on student achievement activities transparently and safely.
