Abstract

This research was conducted to simulate digital image sharpening using the Lusi Richardson deconvolution method. Sharpening was then performed by Lusi richardson deconvolution of the pint spread function of the lens effect. This point spread function is modeled mathematically with a mathematical function approach. The results of the convolution between the Digital Image from a photo of an object are then convolved with the point spread function so as to produce a blurry image. The blurry image is then re-sharpened by deconvolution using the Lucy Richardson convolution method. The results of this deconvolution are then compared with the image of an object photo of reference and then the difference is calculated. The slight difference between the deconvolution result image and the original object photo image indicates that the program is running well. Peak Signal to Noise Ratio (PSNR) Is used to determine image sharpening recovery. The optimum sharpening recovery of deconvolution iteration is obtained in the maximum PSNR value

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

The use of teaching materials has many benefits for students, one of which is to make it easier for students to find information and assist in mastering concepts. This pre-experimental study aims to describe students' mastery of Basic Physics concepts in lectures using e-books. The subjects of this study consisted of all students taking Basic Physics courses at the Biology Education Study Program, University of Mataram, with a total of 27 students. The research was conducted in 7 meetings, starting from October 24 2022 to December 5 2022. The concepts studied consisted of: Static Fluid, Dynamic Fluid, Vibration and Waves, Temperature and Heat. Student concept mastery data was obtained from giving essay tests at the 8th meeting. The level of mastery of the concept is divided into 8 grades namely A, B+, B, C+, C, D+, D, E. Students are declared to have passed if they get grade C, with levels of mastery of concepts ranging from 65 to less than 70. The results showed that the grades the lowest is 66.2 (grade C), while the highest is 91.5 (grade A). The average value of concept mastery is 77.8 (grade B). Thus, it can be concluded that the percentage of students' concept mastery who obtain a pass grade of 100%. The use of e-books can be an alternative teaching material that can be used by lecturers and students in an all-digital era. E-book users can access anytime and anywhere

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.
