Abstract

Penelitian ini bertujuan untuk menganalisis model penggunaan informasi akuntansi pada BUMDES di Desa Pematang Serai Kabupaten Langkat dalam rangka peningkatan Pendapatan Asli Desa melalui pelatihan akuntansi, lama berdiri usaha dan skala usaha dalam penggunaan sistem informasi akuntansi BUMDES di Desa Pematang Serai Kabupaten Langkat dengan pengumpulan data menggunakan kuisioner. Pengujian yang digunakan dalam penelitian ini adalah uji kualitas data, uji normalitas data, analisis regresi linear berganda, dan uji hipotesis. Model regresi yang digunakan dalam penelitian ini adalah model regresi linear berganda dengan bantuan alat uji statistik. Metode pengambilan sampel pada penelitian menggunakan metode Random Sampling (acak) yang diperoleh sebanyak 30 pengelola BUMDES di Desa Pematang Serai Kabupaten Langkat. Hasil uji regresi Hipotesis pertama diterima dan H0 ditolak, dimana hasil uji T pada variabel pelatihan akuntansi diperoleh probabilitas Sig. Sebesar 0,000. yang berarti nilai Sig ≤ 0,05 atau (0,000 ≤ 0,05), Begitu pula dengan nilai T hitung pada pelatihan akuntansi adalah 8,681 . Dan nilai T tabel sebesar 2,0518 Sehingga dapat diperoleh nilai (Thitung ≥ Ttabel) atau (8,691 ≥ 2,0518). dikarenakan pelatihan akuntansi berpengaruh signifikan terhadap penggunaan sistem informasi akuntasi di BUMDES di Desa Pematang Serai Kabupaten Langkat. Hasil uji regresi hipotesis kedua ditolak dan H0 diterima dimana hasil uji T pada variable lama berdiri usaha diperoleh probabilitas sig sebesar 0,329. Yang berarti nilai sig >0,05 atau (0,329 > 0,05), . Begitu pula dengan nilai Thitung -0,995 . Dan nilai Ttabel 2,0518 . Sehingga dapat diperoleh nilai (Thitung < Ttabel) atau (-0,995 < 2,0518) yang artinya bahwa variabel lama berdiri usaha tidak berpengaruh signifikan terhadap penggunaan sistem informasi akuntansi pada BUMDES di Desa Pematang Serai Kabupaten Langkat. Hasil uji regresi hipotesis ketiga ditolak dan H0 diterima dimana hasil uji T pada variable skala usaha diperoleh probabilitas sig sebesar 0,586. Yang berarti nilai sig >0,05 atau (0,586 > 0,05), . Begitu pula dengan nilai T hitung 0,551 . Dan nilai T tabel 2,0518 . Sehingga dapat diperoleh nilai (T hitung < T tabel) atau (0,55551 < 2,0518). yang artinya bahwa variable skala usaha tidak berpengaruh signifikan terhadap penggunaan system informasi akuntansi pada BUMDES di Desa Pematang Serai Kabupaten Langkat.

Abstract

This study aims to analyze the model of using accounting information at BUMDES in Pematang Serai Village, Langkat Regency in order to increase Village Original Income through accounting training, length of business establishment and business scale in using the BUMDES accounting information system in Pematang Serai Village, Langkat Regency by collecting data using a questionnaire . The tests used in this study were data quality tests, data normality tests, multiple linear regression analysis, and hypothesis testing. The regression model used in this study is a multiple linear regression model with the help of statistical test tools. The sampling method in this study used the Random Sampling method (random) which obtained as many as 30 BUMDES managers in Pematang Serai Village, Langkat Regency. Regression test results The first hypothesis is accepted and H0 is rejected, where the results of the T test on the accounting training variable obtain a probability of Sig. By 0.000. which means the Sig value ≤ 0.05 or (0.000 ≤ 0.05), as well as the T value calculated in accounting training is 8.681 . And the T table value is 2.0518 so that a value can be obtained (Tcount ≥ Ttable) or (8.691 ≥ 2.0518). because accounting training has a significant effect on the use of accounting information systems at BUMDES in Pematang Serai Village, Langkat Regency. The results of the second hypothesis regression test were rejected and H0 was accepted where the results of the T test on the long standing business variable obtained a sig probability of 0.329. Which means the sig value > 0.05 or (0.329 > 0.05). Likewise with the value of Tcount -0.995 . And the Ttable value is 2.0518. So that the value (Tcount <Ttable) or (-0.995 <2.0518) can be obtained, which means that the long standing variable has no significant effect on the use of accounting information systems at BUMDES in Pematang Serai Village, Langkat Regency. The results of the third hypothesis regression test were rejected and H0 was accepted where the results of the T test on the business scale variable obtained a sig probability of 0.586. Which means the sig value > 0.05 or (0.586 > 0.05), . Likewise with the calculated T value of 0.551 . And the T table value is 2.0518 . So that a value can be obtained (T count < T table) or (0.55551 < 2.0518). which means that the business scale variable has no significant effect on the use of the accounting information system at BUMDES in Pematang Serai Village, Langkat Regency.

Abstract

Based on previous research, Computational Thinking (CT) skills and learning motivation can be influenced by differences in IQ. Furthermore, learning motivation is correlated with and has an impact on CT skills. However, studies on CT skills, learning motivation, and IQ in mathematics, as well as the relationship between CT skills in mathematics and learning motivation, are still limited. Therefore, this research was conducted to address this gap. This study employed a descriptive quantitative method with a comparative and correlational design. The participants in this study were students from a high school in Medan, with a total of 41 subjects. Data were collected using a mathematical problem-solving test to measure CT skills and a questionnaire to assess students' learning motivation. The data were analyzed using simple and multivariate linear regression. The findings of the study is CT skills of students in the IQ group ≥ 100 were better than those in the IQ group < 100 in solving mathematical problems. There was no significant difference in learning motivation between students in the IQ group ≥ 100 and those in the IQ group < 100. There is a significant relationship and influence of learning motivation on CT skills.

Abstract

Critical Thinking Disposition (CTD) and Computational Thinking Skills (CTS) are essential competencies required to navigate the complexity of 21st-century challenges, particularly in high school mathematics learning. This study aims to describe students’ levels of CTD and CTS after participating in Problem-Based Learning (PBL) and to analyze the relationship between the two variables. A quantitative approach with a descriptive–correlational design was employed, involving 55 tenth-grade students from a private senior high school in Medan selected through purposive sampling. CTS data were obtained through essay-based mathematical problem-solving tests, while CTD was measured using a Likert-scale questionnaire. Descriptive analysis revealed that both CTD and CTS were at a high achievement category with moderate data variability. Pearson correlation analysis showed a strong and significant positive relationship between CTD and CTS (r = 0.723; p = 0.001 < 0.05), indicating that a strong disposition toward critical thinking makes a substantial contribution to the development of students’ computational thinking skills. These findings reinforce that PBL is an effective pedagogical approach for simultaneously integrating dispositional and cognitive aspects and provide important implications for the design of learning that strengthens higher-order thinking skills. Future studies are recommended to expand the scope of variables and employ longitudinal designs to enhance the generalizability of the findings.
