Abstract

The rapid development of information and communication technology has driven significant changes in various fields, including the service sector. Internet-based digital services provide quick and easy access to all needs, such as ordering transportation, food, or even services. On-demand services are services based on customer demand (Anjani & Sujarwo, 2023). This research aims to develop a web-based on-demand computer service system integrated with geographic location using the K-Nearest Neighbor (KNN) algorithm. Difficult access for customers with limited mobility, the lack of location-based partner distribution, and the manual partner search process remain major challenges in conventional computer service. The system was developed using Laravel as the backend framework and MySQL as the database processor, using the KNN method to measure the closest distance between the user's location and the partner based on latitude and longitude coordinates. The results show that the system can automatically provide information in the form of recommendations for the nearest technician partner, which can increase service time efficiency and make it easier for consumers to access professional computer service. A user-friendly interface and a simple ordering process can enhance user experience. This study recommends further system development by integrating digital payment methods and conducting more detailed classification accuracy testing to improve the quality of the service system's recommendations.

Abstract

A good and strong visual identity is a tool in building a brand because it functions to form an impression that influences consumer perceptions. The longer people are familiar with a particular brand, the more likely they are to have a positive attitude toward that brand. In fact, by changing the visual identity of a product, it can also change or improve the brand image in the community and create an Identity. This is what is meant by the concept of brand loyalty, and vice versa if consumers get a negative stimulus from a visual identity of a brand, the biggest possibility is that consumers cancel the desire to try or make repeat purchases. To represent an identity, a logo and a visual system are needed, so that they are important assets in a company, institution, or product as an identity. This need is needed by various levels of business, including MSMEs. This community service program emphasizes increasing the competence of MSME actors in maximizing the potential for selling business products by strengthening the visual identity of the logo. The implementation of this service involves teaching staff (lecturers) from the Information Systems Study Program, Informatics Engineering and Communication Studies as well as students. This program collaborates with as many as 15 (Fifteen) MSME participants to create an identity design and its application media. In its implementation, the design starts from product analysis and then visual output is made, from illustrations to colors.

Abstract

The rapid growth of user reviews on Google Maps is not always accompanied by ease in understanding the sentiment contained within them, causing tourists and the general public to face difficulties in determining shopping centers with good reputation and service quality. The lack of information regarding visitor satisfaction levels, along with various facility-related issues such as crowd density, limited parking space, and the comfort of public facilities, combined with the large number of subjective and unstructured reviews, makes manual sentiment analysis ineffective and potentially leads to less accurate conclusions. This investigation aims to analyze sentiment from Google Maps reviews of shopping centers in the city of Semarang utilizing the Support Vector Machine (SVM) and Naïve Bayes methods. The data were collected from five shopping centers with the highest number of reviews in Semarang, namely Paragon Mall, Mall Ciputra, Java Mall, DP Mall, and Queen City Mall. The investigation method includes text preprocessing, TF-IDF weighting, and sentiment classification into three classes: negative, neutral, and positive. The dataset was divided into training and testing data with a ratio of 80:20. The outcomes reveal that the Naïve Bayes method achieved an accuracy of 85.56%, while the Support Vector Machine (SVM) method achieved an accuracy of 89.20%. Considering the outcomes, the SVM method performs better in classifying sentiment from Google Maps reviews of shopping centers in Semarang.
