Abstract

The growth of tourism in the digital era encourages the use of social media as a source of visual data for destination analysis. This study aims to classify and map tourist attractions in West Kalimantan using a transfer learning-based Convolutional Neural Network (CNN) method with the MobileNetV2 architecture. A total of 454 images were collected through web scraping from the Instagram account @enjoykalbar, then through a process of elimination, augmentation, normalization, and manual labeling based on the West Kalimantan Disporapar tourism categories, namely Hills, Beaches, Cascades, Culture, Lakes, Rivers, Caves, and Forests. The dataset was divided into training data (70%), validation (20%), and test (10%). The model was built by freezing the initial layers of MobileNetV2 and adding a classification head, then drilled for 20 epochs using the Adam Optimizer and EarlyStopping and ReduceLROnPlateau callbacks. The training results showed a training accuracy of 95.8%, validation accuracy of 88.1%, and test accuracy of 80%. Further evaluation using the classification report yielded an overall accuracy of 89%, with an average precision of 0.93, a recall of 0.86, and an F1-score of 0.88. The model was then integrated into a category- and coordinate-based interactive mapping system to display the distribution of tourist attractions across 12 districts and 2 cities. The results demonstrate that the CNN transfer learning approach is effective for tourism image classification and supports spatial visualization in tourism promotion and planning.

Abstract

Strategic alignment between business and Information Technology (IT) remains a critical factor for organizational effectiveness and competitive advantage. However, measuring and achieving this alignment presents complex challenges for organizations across various sectors. Objective: This article analyzes the measurement of business and IT strategic alignment using the Strategic Alignment Model (SAM) and its maturity extension (SAMM). Methods: The study reviews and synthesizes empirical applications of SAM across healthcare, financial services, manufacturing, and other industries, examining both Henderson and Venkatraman's original model and Luftman's maturity assessment framework. indings reveal that organizations typically demonstrate alignment maturity levels ranging from 2 to 4 on Luftman's five-point scale, with communication, governance, and skills emerging as critical dimensions requiring attention. Organizations undergoing digital transformation often experience transitional disconnects between evolving expectations and underlying IT structures. The SAM framework effectively diagnoses alignment gaps but requires contextual adaptation and consideration of social dimensions including values, beliefs, and success criteria. Successful business-IT alignment measurement demands multi-dimensional assessment, continuous adaptation of alignment perspectives, and integration of both technical and social factors.
