Abstract

The purpose of this study was to evaluate the validity of worksheets based on the Collaborative Argumentation Learning Model (CALM) in order to improve students' science literacy level on alternative energy materials. An R&D approach combined with the ADDIE development model was the methodology used in this study. The three stages used in this research are: analysis, which involves identifying students' needs related to student worksheets on alternative energy materials; design, which involves organizing the worksheets created; and development, which involves collecting and validating the worksheets. The construction and content components of the LKPD can be used to evaluate its validation. One high school teacher and two knowledgeable lecturers became the three validators whose results were calculated as part of the data analysis technique. The advantages of the worksheets include being able to train science literacy indicators, using the argumentation-based CALM learning approach, and including real-world situations. The first recommendation from the validators was to pay close attention to the elements of scientific argumentation used as well as the signs of science literacy. The findings showed that the average validity score from the three validators was 96.21% for the content aspect and 97.22% for the construction aspect. This finding shows that the average value of the overall validity of the worksheet, with very valid criteria, is 96.72%. Thus, it can be said that the use of CALM-based worksheets to improve science literacy related to alternative energy content is appropriate for use during the educational process. This study shows that students benefit from using the argumentation component in physics learning, and this can be one way to help students become more savvy in science literacy.

Abstract

This study aims to identify variables that affect profitability in food and beverage companies listed on the Indonesia Stock Exchange. The addition of the quick ratio variable as an independent variable is a novelty in this study. Liquidity is measured by the current ratio, net working capital, and quick ratio while company efficiency is measured using total asset turnover. Profitability is measured by ROA and ROE. This study also includes control variables such as size, age, leverage ratio, and company growth rate to analyze the effect on profitability. This research method includes collecting data from 20 food and beverage companies over five years (2019-2023) with a total of 100 data that meet the criteria with the application of data processing analysis using panel data regression analysis techniques. The results of the study found that the current ratio has a significant positive effect on ROA and has no effect on ROE. Net working capital, company size, and growth rate do not affect ROA and ROE. Total asset turnover has a significant positive effect on ROA and ROE. The quick ratio and age have a significant negative effect on ROA and do not affect ROE. In addition, the debt ratio has a significant positive effect on ROE and does not affect ROA. This study confirms that the efficiency of asset use and liquidity management plays an important role in increasing the profitability of companies in the food and beverage sector, especially through the effect on ROA and ROE.

Dalam kegiatan ini seluruh siswa menyanyikan yel-yel dari masing-masing kelas untuk meningkatkan semangat siswa. Terakhir adalah kegiatan ice breaking dimana siswa menonton film tentang sumpah pemuda. Selain menonton film, ada juga pembacaan puisi dari perwakilan mahasiswa. Usai menonton film, para siswa diberikan kuis berhadiah untuk menambah semangat mereka untuk selalu mengingat sumpah pemuda. Program yang diselenggarakan oleh KKN-T Unesa Tuban ini sangat didukung oleh pihak sekolah. Serangkaian kegiatan berhasil mencapai target yang diharapkan, mulai dari upacara hingga ice breaking. Acara tersebut telah memberikan kesan yang sangat berarti bagi warga SDN Prunggahan Wetan.

In Tongklek art, all musical instruments used can be associated with the application of physics concepts. However, due to limited human resources, the study of the physics concepts contained in the art of Tongklek has received little attention. This study aims to identify the concept of physics in the local wisdom of Tongklek in order to increase public knowledge. In this study using a descriptive research method with a qualitative approach. The analysis technique used is data reduction.

In every musical instrument in the Tongklek art there is a concept of physics, namely the material of sound waves, especially organ pipes. The source of the sound of the Tongklek art, on average, comes from musical instruments that have a certain volume, there are forms where all fields are closed, there are also some of these things which are named as air columns as the source of the vibrations.
