Abstract

This research aims to determine the effectiveness of differentiated learning on the social skills of class IV students in science subjects at SDN 19 Kelapa. The population in this study were 21 class IV students. The sample in this study amounted to 21 people. The sampling technique in this research was using a saturated sampling technique. The method used in this research is an experimental method in the form of Pre-Experimental Designs with the One-Group Pretest-Posttest Design type. Data collection was obtained using activity, observation and documentation rubrics. The data analysis techniques used in this research are normality testing and hypothesis testing. The results of the data analysis data calculations obtained an average posttest result value of 81 (good) in the category "Very Effective. Based on the results of the normality test analysis using the Shapiro-Wilk test with the results of the pretest normality test calculations, it can be obtained that the pretest value is 0.087 > 0.05 and the posttest value is 0.148 > 0.05, so it can be concluded that the data is normally distributed. Meanwhile, the results of the hypothesis test analysis used the Paired-sample-t-test with the hypothesis results contained in Sig (2 tailed) that between the pretest and posttest had a value of 0.00 <0.05. This shows that Ho is rejected and Ha is accepted, meaning that there is effectiveness of differentiated learning on the social skills of class IV students in science subjects at SDN 19 Kelapa. This research needs to be developed by further researchers in subjects other than Natural Sciences such as PPKN, Indonesian, Mathematics so that innovation and novelty can be found related to differentiated learning for students' social skills in the learning process.

Abstract

This study aimed to examine the effects of Current Ratio (CR), Return on Assets (ROA), and Assets Growth (AG) on the debt-to-equity ratio (DER) of PT Indofood Sukses Makmur Tbk from 2014 to 2023. The research employed descriptive and verification methods using a quantitative approach. Data was collected through documentation, utilizing secondary data from quarterly financial reports. The study used purposive sampling. Results of partial hypothesis testing (t-test) revealed that the Current Ratio (CR) had a significant positive effect on the debt-to-equity ratio (DER). In contrast, Return on Assets (ROA) and Assets Growth (AG) had positive but non-significant effects on DER. Simultaneous hypothesis testing (F-Test) showed that CR, ROA, and AG significantly impacted DER at PT Indofood Sukses Makmur Tbk, accounting for 50.9% of its variation. The remaining 49.1% was attributed to other factors not examined in this study

Abstract

Indonesia is known as a country with many natural and man-made tourist destinations, especially the South Tapanuli region which has marine, natural and man-made tourist destinations that are attractive and worth visiting for domestic and foreign tourists. In 2023, the number of tourists visiting South Tapanuli will be 422,688 people. This research aims to estimate or predict the number of tourists visiting South Tapanuli in the next 6 years using the Double Exponential Smoothing (DES) method with amortized parameters. Double exponential smoothing (DES) is a forecasting method by predicting time series data with a trend model. To overcome overprediction, an attenuating parameter is added which can reduce the estimated value exponentially. This research also aims to compare the estimated number of tourists in South Tapanuli Regency using the T test. This research shows that the estimated number of tourists coming to South Tapanuli Regency in the next six years will increase. For the t test carried out, the results obtained were tcount < ttable (2.014 < 2.015).

Abstract

The objective of this study is to determine the outcomes of the requirements analysis and learning materials for electrolyte and non-electrolyte solution materials. Additionally, learning materials will be developed utilising computational chemical calculations and visualisation of the results to create learning media based on the National Education Standards Agency (BSNP) requirements. This kind of study uses the ADDIE development model and is referred to as development research. There are five steps in the current ADDIE model: analysis, design, development, implementation, and evaluation. The entire student body of one of the senior high schools in Padangsidempuan City, North Sumatera, Indonesia, served as the study's population. The participants in this research were senior high school students from Padangsidempuan City, North Sumatera, Indonesia. The use of a purposive sampling technique yields grade X as the research sample. An inquiry form derived from the National Education Standards Agency was used as the research tool. Utilising a significance level of 5%, the data analysis was conducted using the SPSS 22 for Windows software. The investigation's findings demonstrate the need for educational materials to help pupils struggling with learning. Based on 95% validation findings, the learning materials for both electrolyte and non-electrolyte solutions visualise the outcomes of computational chemical calculations.

Populasi objek penelitian sebanyak 55 perusahaan dalam 5 (lima) tahun dan sampel yang digunakan sebanyak 22 data. Pengolahan data menggunakan eviews 10. Tujuan dari penelitian ini adalah utuk mengetahui komite audit, tingkat utang dan kinerja perusahaan terhadap manajemen laba baik secara parsial maupun simultan. Hasil penelitian menunjukan bahwa secara simultan komite audit, tingkat utang dan kinerja perusahaan berpengaruh terhadap manajemen laba karena dari hasil perhitungan diperoleh nilai Prob (Fstatistic) sebesar 0,045637 < 0,05. Kemudian secara parsial variabel komite audit tidak berpengaruh terhadap manajemen laba, tingkat utang dan kinerja perusahan berpengaruh terhadap manajemen laba.
