Abstract

This research aims to determine the effect of Digital-Worksheet (E-LKPD) with the Physics Toolbox Sensor Suite on understanding physics concepts of high school students in South Lampung, Lampung. A total of 60 students were involved in this research and were divided into two classes, namely the experimental and control classes. Data were analyzed using n-gain, independent sample t-test, and effect size. The research results showed that the average N-gain in the experimental class was 0.73 in the high category, while it was 0.58 in the medium category in the control class. There was a significant difference in n-gain in understanding concepts (sig.2-tailed < 0.05) between the experimental and control classes. This result is also reinforced by the effect size, which is very high, namely 1.319. This shows that the E-LKPD with the Physics Toolbox Sensor Suite is able to improve understanding of physics concepts, especially regarding Vibration. E-LKPD with the Physics Toolbox Sensor Suite can help students understand concepts, improve work activities, and reduce misconceptions.

Abstract

In the era of globalization and business digitalization, improving the quality of customer service is a crucial aspect for company success. Companies that are able to provide optimal and responsive service tend to maintain customer satisfaction and compete effectively in an increasingly tight market. Therefore, the use of the Information Technology Infrastructure Library (ITIL) framework is a strong foundation for managing and improving service quality. This research focuses on analyzing service quality in the ITIL V3 Service Design domain, by applying this framework to a significant e-commerce application, namely Lazada. Lazada, as a leading platform in Southeast Asia, has been an example of providing superior customer experience through its services. This research explains the role of ITIL in managing service quality, with an emphasis on the Service Design domain. This study uses a combination of methods, including literature study, questionnaire survey of Lazada users, and observation of application infrastructure. The analysis results show that Lazada has reached a high level of maturity in ITIL V3 Domain Service Design, with all subdomains reaching maturity level 4. However, there is room for improvement, especially in information security. The conclusion shows that Lazada can continue to maintain customer satisfaction and competitiveness in a competitive market by continuing to improve service quality, especially in aspects found through gap analysis.
