Abstract

Image segmentation is crucial in image processing and computer vision, with multilevel thresholding (ML-ISP) offering robust solutions for complex images. However, effectively applying ML-ISP to RGB color images remains a challenge due to computational complexity and the limitations of traditional optimization algorithms, such as the Grey Wolf Optimizer (GWO). This study proposes an Inspired Grey Wolf Optimizer (IGWO) to address these issues and enhance ML-ISP for RGB color images. The performance stability of IGWO is comprehensively evaluated using three distinct objective functions: the Otsu method, the Kapur Entropy, and the M. Masi Entropy. Qualitative and quantitative analyses using PSNR, SSIM, and UQI were conducted on benchmark images. Results consistently demonstrate that IGWO, particularly with M. Masi Entropy, achieves superior segmentation quality. This research incorporates GridSearch-based hyperparameter tuning. The findings highlight the effectiveness and robustness of the proposed IGWO approach for complex ML-ISP tasks on color images.

Abstract

Reading is a fundamental skill for intellectual growth and critical thinking development, yet Indonesia faces significant literacy challenges with only 1 out of 1000 the population reads regularly according to UNESCO data and the Indonesian National Assessment Program revealing that merely 6.06% of students possess good literacy skills. The majority of social media platforms promoting instant gratification through short-form contents have further decreasing attention spans and reading habits. This study aims to design “Bookwormer”, a social literacy platform that supports reading habits through book exploration, community engagement, and distraction-free environment. The study used Design Thinking methodology, consists of five steps: Empathize, Define, Ideate, Prototype, and Test. A prototype was developed, featuring a home page, trending books exploration, reading clubs, and personal library with reading goal statistics. Usability testing using System Usability Scale (SUS) with 20 participants yielded an average score of 81.25, indicating excellent usability. Bookwormer is able to address identified user needs and contributes in improving digital literacy culture in Indonesia.

Abstract

In the digital era, the role of information technology in facilitating services has presented both challenges and opportunities for businesses seeking to provide exceptional customer service. To remain competitive and maintain customer satisfaction, businesses need to implement technology in the form of service management and customer management information systems. Using technology, community service endeavors aim to establish a service management information system and consumer management. For employees and clients, assistance is provided through technology transfer, socialization, training, and technical support. The outcomes of this assistance indicate advancements in consumer data management and the implementation of more effective technology. The PKM implementation team at INSTIKI discovered that active participation from partners and customers contributed to the success of the program. Partner participation helps identify actual needs and issues in the use of information systems, enabling mentoring programs to be tailored to user requirements and optimize service quality in the digital era.
