Abstract

Proper post-harvest handling is very necessary to maintain product quality and extend the shelf life. One way to extend the shelf life of agricultural products, including cayenne pepper (Capsicum frutescens L.), is by drying techniques. Blanching pretreatment before drying can maintain the condition of the dried product so that it can maintain the final product quality. The aim of this research was to analyze the water content, water content ratio (MR), drying rate, drying constant of cayenne pepper using a rotary rack type of hybrid dryer. The use of rotary racks type hybrid dryer is a cheaper drying alternative and the use of rotary racks is able to standardize the water content in the cayenne pepper drying process. The research was carried out with two treatments, namely with and without blanching process at a temperature of 90°C for 5 min. The second factor was drying temperatures were are 43 47℃, 48-52℃ and 53-57℃ until the cayenne pepper reach the water content according to the reference, namely in the range of 5-8%. From the research results, it was obtained that the lowest water content of cayenne pepper was given pretreatment blanching at a temperature of 53-57°C, namely 6.43% with a drying time of up to 14 h. The drying rate of blanched cayenne pepper was higher than that of unblanched cayenne pepper. Keywords: Blanching, Cayenne pepper, Drying.

Abstract

This systematic literature review aims to examine the effectiveness of virtual laboratory implementation in enhancing students’ motivation and interest in learning based on scientific articles published between 2015 and 2024. A total of 17 empirical studies were analyzed using a qualitative descriptive content analysis method. The articles were collected through a systematic search using the Publish or Perish application in the Google Scholar and OpenAlex databases with the keywords: “virtual laboratory,” “virtual lab,” “PhET simulation,” “learning motivation,” and “learning interest.” Most of the analyzed studies were conducted at the junior and senior high school levels (SMP and SMA). The results indicate that all analyzed studies (100%) reported a positive effect of virtual laboratories on students’ affective domains, reflected in increased motivation scores and learning interest. PhET Simulation emerged as the most widely used platform (52.94%), particularly in Physics topics such as Archimedes’ Law, Heat and Temperature, and Harmonic Motion. Publication trends showed a significant peak in 2022 (29.41%), corresponding to the accelerated adoption of digital learning technologies during the post-COVID-19 era. The findings suggest that the effectiveness of virtual laboratories is driven by dynamic visualization of abstract concepts, interactive feedback, and flexibility in conducting repeated experiments. Overall, the findings indicate that virtual laboratories are effective learning media for improving students’ motivation and interest, particularly at the junior and senior high school levels. Their effectiveness is further supported by the integration of appropriate instructional models and the teacher’s role as a facilitator.

Abstract

Students' understanding of mathematical concepts remains relatively low, necessitating technological innovations in education to address this issue. A promising solution is the integration of GeoGebra as an interactive learning tool. This study aims to evaluate the effectiveness of GeoGebra in mathematics education regarding students' conceptual understanding through a systematic literature review. Utilizing a Systematic Literature Review (SLR) method with a qualitative descriptive approach, data were sourced from scientific articles in national and international journals via Google Scholar, ProQuest, and Springer Nature databases published between 2016 and 2025. The literature selection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, resulting in 16 articles that met the inclusion criteria. The findings demonstrate a consistent pattern wherein the utilization of GeoGebra significantly enhances students' conceptual understanding compared to conventional methods. This improvement is evidenced by increased average learning outcome scores, higher post-test than pre-test results, and statistically significant differences between the GeoGebra and conventional groups. Furthermore, GeoGebra proves effective across various educational levels and mathematical topics due to its capacity to visualize abstract concepts dynamically and interactively.

Abstract

This study investigates the role of game-based educational tools within a Project-Based Learning (PBL) framework in enhancing students' problem-solving skills. Faced with the demands of Industry 4.0 and the Sustainable Development Goals (SDGs), there is a critical need for innovative learning approaches that foster problem-solving and creativity among prospective teachers. This research adopted a 4D model (Define, Design, Develop, Disseminate) to develop a game-based PBL learning device, tested over six months with 27 university students across different semesters. The findings indicate that the integration of educational games significantly contributes to the development of problem-solving abilities. Students actively engaged in real-world project challenges through games, which facilitated the identification, formulation, strategy implementation, and solution verification stages of problem-solving. While the 'identifying problems' and 'verifying solutions' aspects showed areas for further improvement, the overall process demonstrated a positive impact on students' capacity to tackle complex issues effectively. This highlights the potential of game-based PBL as an engaging and effective pedagogical tool for cultivating essential problem-solving competencies in higher education.

Abstract

ABSTRACT The development of digital technology has driven innovation in creating more interactive and engaging learning materials for students. This study aims to analyze the implementation strategy for gamification-based digital learning materials to increase student learning motivation, drawing on a review of scientific literature. The method used is a systematic literature study by reviewing research articles published between 2022 and 2025 from various national and international journals relevant to the topic of gamification in education. A total of 15 journal articles were analyzed using content analysis techniques to identify implementation patterns, types of platforms used, and their impact on student learning motivation. The results of the study indicate that the application of gamification in digital learning materials, such as the use of points, levels, badges, leaderboards, and interactive challenges, has been proven to increase learning motivation, student engagement, and a more enjoyable learning experience. In addition, the integration of gamification through various digital platforms such as Quizizz, Kahoot, Wordwall, and Learning Management System (LMS)-based learning applications has a positive influence on active student participation in the learning process. However, the effectiveness of gamification implementation is greatly influenced by learning design, teacher readiness to utilize technology, and the availability of digital infrastructure. Therefore, strategies for implementing gamification-based digital teaching materials need to be systematically designed to support more interactive, innovative learning and be oriented towards increasing student motivation in the digital era.
