Abstract

Physics cannot be separated from things that are conceptual. The concept of physics is a description or definition of the physical variables that exist in events in the universe. It's just that, often there is a problem in students' understanding of concepts where there is a discrepancy between the definitions that are understood and those conveyed by experts. This problem is called a misconception. Misconceptions can occur because the concepts that students understand through observation of everyday events are different from the theories obtained in the learning process in class, one of which is on black body radiation material. One learning model that can overcome misconceptions is a problem-based learning model or Problem Based Learning (PBL). The purpose of this study was to reduce misconceptions about black body radiation and to determine the effectiveness of PBL in overcoming misconceptions about black body radiation. This research is a type of experimental research using a pre-experimental design pre-test post-test group. The results showed that PBL can reduce misconceptions and is quite effective as an effort to reduce misconceptions about black body radiation material marked with an N-Gain value of 0.55.

Abstract

Microalgae are highly valuable across various industries due to their rich nutritional content and positive environmental impact. In the fast-growing field of aquaculture aimed at meeting global food needs, integrating microalgae technology can be highly beneficial. This literature review explores the diverse roles of microalgae in enhancing aquaculture, focusing on their nutritional benefits, water quality management, larviculture, Integrated Multi-Trophic Aquaculture (IMTA) systems, and bioremediation. Microalgae are excellent natural nutrient sources, offering high protein content, omega-3 fatty acids, vitamins, minerals, and antioxidants, vital for aquatic organism growth and health. Their contributions to water quality maintenance, larval stage nutrition, and waste nutrient uptake are critical. Additionally, microalgae play a pivotal role in IMTA by acting as primary producers and minimizing environmental impact. The review emphasizes challenges like economic constraints and strain optimization, underscoring the need for further research to fully leverage microalgae's potential in aquaculture, promising advancements to revolutionize the industry and enhance global food security.

Abstract

A computational thinking approach is an approach to thinking and reasoning by computer scientists. Computational thinking skills can be adopted as an approach to solving a problem and analyzing the solution. The computational thinking approach is not limited to computer science but can also be applied to other disciplines through problem-solving. The computational thinking approach has been integrated into various instruments and learning media. The purpose of this research is to see the potential of the computational thinking approach to be integrated into learning media to improve problem-solving skills and to discuss the integration of computational thinking in various learning tools and media. This research method uses literature studies with 6 international articles as the main source from scopus.com and 19 articles as supporting articles from scholar.google.com. The results of the study show that the computational thinking approach has the potential to be integrated into various learning tools and media as a means of increasing problem-solving skills.

Abstract

Fish crackers are one of the most popular snacks in Southeast Asian countries, including Malaysia. Traditionally, the process of fish crackers drying usually uses sun drying method. The problem of this method is uncontrollable weather conditions. Drying of fish crackers requires an alternative in the drying process. The heat pump is the most effective and controllable alternative dryer in reducing the moisture content of the material. Air Conditioning (AC) is one type of heat pump. The heat produced by the AC condenser can be used to dry fish crackers. In this study, the AC utilization as a heat pump system to dry fish crackers has an Evaporate Capacity (EC) of 1,838kg/h, a Specific Moisture Extraction Rate (SMER) of 1,998kg/kWh, and a Specific Energy Consumption (SEC) of 0.425kWh/kg of dry crackers. This drying machine is also economically feasible because it has an NPV> 0 which is RM28201.58 with an investment period of 1 year.
