Abstract

Tujuan pengabdian ini adalah pembuatan air bersih dan penyediaan tempat sampah yang harus dimulai dengan pendekatan preventif dan persutif, yaitu melakukan sosialisasi, penyuluhan dan pemberian contoh berupa pembuatan teknologi/alat sederhana yang langsung dipraktekkan dan diinstalasi serta dibagikan kepada masyarakat. Teknologi sederhana penjernih air (traditional water purefier) yang dibuat untuk menyaring air kotor menjadi air bersih. Disamping itu potensi sampah menjadi pemicu dan penyebab utama air kotor dan penyebaran penyakit menular melalui air, diperlukan penyediaan tempat sampah agar mempunyai rasa peduli dan mulai merubah kesadaran dan perilaku agar sampah tidak dibuang sembarang. Untuk memberikan contoh efektif dibuat tempat pembuangan sampah sederhana (organik dan an organik) dibagikan ke masyarakat dan diletakkan kantor kepala desa dan beberapa tempat dalam lokasi Kelurahan Sidomukti. Diharapkan dengan kegiatan pengabdian ini sangat membantu masyarakat agar memahami pentingnya air bersih dan hidup bersih untuk kesehatan, karena air penting untuk kebutuhan sehari-hari. Hal lain kegiatan ini dapat memberikan wawasan dan pemahaman agar tidak membuang sampah sembarang tempat atau ke sungai. Kegiatan pengabdian ini dapat memberikan masukan dan membantu program Pemerintah Kabupaten Asahan dalam mewujudkan lingkungan yang rapi, indah dan sehat.

Abstract

This study analyzes the effect of Current Ratio (CR), Debt to Asset Ratio (DAR), and Debt to Equity Ratio (DER) on Return on Asset (ROA) in insurance sub-sector companies listed on the Indonesia Stock Exchange during 2021-2024. Profitability in insurance companies is important to examine because this sector has characteristics related to risk management, claim obligations, liquidity needs, and financing structures that differ from non-financial companies. This research applies a quantitative approach with a causal associative method. The data used are secondary data obtained from annual financial statements published on the website of the Indonesia Stock Exchange. The population consists of 19 insurance companies, while the sample was selected using purposive sampling, resulting in 9 companies and 36 observations. Data were analyzed using multiple linear regression with SPSS 27, preceded by assumption tests consisting of normality, multicollinearity, heteroscedasticity, and autocorrelation tests. The results indicate that CR has no significant effect on ROA, suggesting that liquidity is not the main factor in improving profitability among insurance companies. DAR has a positive and significant effect on ROA, indicating that assets financed by debt can support profit generation when managed productively. DER has a negative and significant effect on ROA because dependence on debt compared with equity may increase financial expenses and reduce profitability. Simultaneously, CR, DAR, and DER have a significant effect on ROA. The Adjusted R Square value of 0.275 indicates that 27.5% of ROA variation is explained by the three independent variables, while 72.5% is affected by other outside factors.

Abstract

This research aims to determine the effect of using Canva-based video learning media on the mathematical problem solving abilities of class XII students at SMA Negeri 1 Air Joman. This type of research is quasi-experimental with a two-group pretest and posttest research design. The population in this study were all students of class XII Science consisting of 3 classes. The research samples used were 2 classes (Class XII IPA-2 and XII IPA-3) with 30 students in each class. In class XII IPA-3 was an experimental class using Canva-based learning video media and in class XII-2 as a control class without using Canva-based learning video media. After the learning was completed, a posttest was obtained with an average result for the experimental class of 80.5 and the control class of 76.4. The t-test results obtained t_count (3.774)> t_table (2.001). H_a is accepted, thus there is a positive and significant influence in the use of Canva-based video learning media on the mathematical problem-solving abilities of class XII students at SMA Negeri 1 Air Joman.

Abstract

Based on the results of data analysis and discussion that have been carried out regarding the application of the Problem Based Learning model with the help of the Brain Math application on students' mathematical reasoning abilities, it was obtained that the t-test results obtained t_(count)> t_(table) (8.70> 1.672) then H_(0) was rejected and H_(1) was accepted. So it can be concluded that there is an influence of the Problem Based Learning model on students' mathematical reasoning abilities. This means that the mathematical reasoning abilities of students who are taught using the Problem Based Learning model with the help of the Brain Math application are better than the mathematical reasoning abilities of students who are taught using the direct learning model.
