This study aims to describe the application of the Discovery Learning learning model assisted by Powerpoint media to students of class X IPA 3 of SMA Negeri 2 Merauke in improving the results of physics learning. This type of research is PTK using a descriptive approach consisting of 2 cycles. Based on the results of this study, it can be concluded that discovery learning learning models make students able to become more active and motivated to find their own solutions to the problems faced. The use of powerpoint media that displays moving images also makes learning more interesting. This is evidenced by an increase in scores at the end of each cycle. To increase the enthusiasm of students, then at the end of the cycle an award is given in the form of congratulations to students or groups that excel.  Keywords: Media Powerpoint, Discovery Learning, Learning Outcomes

Pendekatan multirepresentasi merupakan salah satu pendekatan yang menekankan beberapa sudut pandang makna dalam bentuk representasi verbal, gambar, persamaan, diagram, tabel dan grafik. Bantuan pendekatan multirepresentasi dalam pembelajaran fisika dapat meningkatkan proses dan evaluasi pembelajaran fisika. Beberapa fitur multirepresentasi dalam pembelajaran fisika memberikan dampak yang signifikan pada laur pembelajaran fisika. Secara umum tujuan penelitian ini adalah untuk mendeskripsikan secara kualitatif peranan pendekatan multirepresentasi dalam meningkatkan kualitas pembelajaran fisika secara komprehensif. Secara khusus kajian penelitian ini adalah pendekatan multirepresentasi dapat terintegrasi ke dalam beberapa model, media, strategi dan metode pembelajaran. Fisika serta pengaruhnya terhadap kemampuan kognitif mulai dari level rendah hingga level tinggi.  Metode penelitian ini adalah kualitatif dengan pendekatan kajian Pustaka dengan berbagai sumber berupa artikel jurnal dan beberapa literatur lainnya. Hasil review sumber referensi menunjukan bahwa pendekatan multirepresentasi dapat dintegrasikan pada beberapa model, media, strategi, metode, dan pendekatan pada pembelajaran fisika sehingga mampu meningkatkan beberapa kemampuan kognitif seperti kemampuan pemecahan masalah, argumentasi, pemahaman konsep fisika siswaKata kunci: Pendekatan Multirepresentasi; Pembelajaran Fisika; Kajian Literatur

Understanding the concept of physics is the basic cognitive skill to understand, know, apply and analyze a physical phenomenon.  Problems of conceptual knowledge of physics Students are minimal causing their inability to solve problems with Physics. The understanding of physical concepts can be learned in several ways, one of which is based on conceptual knowledge. Conceptual knowledge can be classified based on several sub dimensions of knowledge including knowledge of classifying, generalizing, basic or general concepts. The purpose of this research is to analyze and describe the understanding of physical concepts based on several indicators of conceptual knowledge through the Quizizz Online Game application. This research uses quantitative-qualitative mixed research methods that are interpreted together. Data retrieval techniques use test instruments and in-person interviews. The results showed that the average understanding of student concepts is in a moderate category with a concept understanding index reaching 47%. Students' concept understanding on each conceptual knowledge such as classifying, generalizing knowledge and knowledge of concepts or theories with results at a moderate level

Field and experimental data on aquatic ecosystem species show the effect of fear on changing prey demographics. The fear effect has an impact on aquatic ecosystems, such as species migration to settled areas. In this paper, the type of research described is a literature study. The cost effect assigned to the reproductive system of the prey population and the predation function response are given as Holling Type IV for research purposes to model the fear effect. Some research novelties, the equilibrium points are all shown in the population dynamics system model with an analysis of positive equilibrium. Positive and biologically realistic equilibrium points were analyzed using the Routh-Hurwitz criterion which is mathematically a local asymptotically stable. A pair of imaginary eigenvalues with a negative real part can increase population growth. An equilibrium region showing equilibrium for several parameters such as extinction, no predators, and two populations coexisting in a sustainable manner. The correlation and fluctuation of fear and fear cost were investigated to obtain a better model. The results of the numerical simulations show that the prey population becomes more daring to fight or fighting power with significant prey growth rates or high predator mortality rates. Doi: 10.28991/ESJ-2023-07-02-06 Full Text: PDF

Indonesia is a country rich in cultural diversity, with each culture having its own regional language characterizing the area. The Muyu language is one of the regional languages, used by the Muyu tribal community in Boven Digoel Regency, Papua Province. The language is now under the threat of abandonment by the Muyu community, especially the younger generation. One of the causes is the lack of written learning media for the language to be inherited by older speakers in the form of books and electronic dictionaries. This study will try to develop an Android-based Muyu-Indonesian-English dictionary application using the waterfall method (classic life cycle). The aim is to test students' preferences and attitudes towards the development of Muyu language knowledge. The research sample consisted of 40 respondents consisting of Muyu students at Musamus University. A questionnaire was used to measure the extent of student responses to the use of the Muyu-Indonesian-English dictionary application. The test results show that the system has no errors in carrying out the functions that have been created previously at the manufacturing stage. The three-language Muyu-Indonesian-English dictionary application is able to search for vocabulary properly and correctly in Muyu, Indonesian, and English. The attitude of students towards the usefulness of this dictionary application is measured at the medium category, meaning that the application is useful as a tool to facilitate students of the Muyu language, especially Android users, in finding vocabulary in three languages, and can be a tool for learning the Muyu language and preserving local wisdom so that it does not become extinct. Doi: 10.28991/esj-2021-SP1-06 Full Text: PDF
