Abstract

This study discusses the convolution or the sum of independent and identical random variables, where the random variables are the Negative Binomial distribution and the Exponential distribution, so that the resulting distribution is known as the Negative Binomial -Exponential distribution. The purpose of this study is to find the characteristics of the distribution including the expected value, the variance value, the moment generating function and the characteristic function. This property is obtained by using theorems and lemmas that relate to the properties of a distribution. It is found that the expected value, variance value, moment generating function and characteristic function of the Negative Binomial-Exponential distribution.

Abstract

This study aims to determine the effect of factory overhead costs and direct labor costs on sales results in Pak May Padang's baking pan business. Taking this title is based on the phenomenon that many business actors do not understand the calculation of production reports so that sales results are not clear, as we can see for ourselves business actors often neglect recording financial reports, the need to know sales results so that they can determine the number of products to be produced and sold in more detail. This study uses a type of quantitative research. The data taken is in the form of secondary data by conducting direct interviews with business owners, by preparing question materials and looking at records of factory overhead costs and direct labor costs during the period 2018 to 2022. This study conducted a classic assumption test, hypothesis testing using SPSS version 21. With the results of the study stating Seeing the results of the tests that have been carried out proves that partially Factory Overhead Costs have a significant effect on Sales Results, direct labor costs have no significant effect on sales results and simultaneously both variables have a significant effect on Sales Results, and can also be seen Adjusted R Square of 0.501 or 50.1% This means that 50.1% of the Sales Results variable is influenced by Factory Overhead Costs and Direct Labor Costs, the remaining 49.9% is influenced by other variables outside of this research variable.

Abstract

This study is entitled regression analysis and correlation between product quality and purchasing decisions for Oppo smartphone products in Kota Pariaman. Statistical science can be used in estimating consumer purchasing decisions involving product quality. The number of respondents amounted to 16 data taken by the proposive sampling method. The method used is Simple Linear Regression. The result of the equation is Y ̂=184.41-0.6X. The degree of relationship or Pearson correlation between variables X and Y is 77.7% which is categorized as having a high relationship. While the results of the F test obtained F count of 47.85 and F table of 4.6, because the results of F count were greater than F tables, which meant that the product quality variable had an effect on the purchasing decision variable.

Abstract

Penelitian ini didasari atas rendahnya hasil belajar siswa. Faktor yang mempengaruhinya adalahpembelajaran masih didominasi oleh Guru, dan siswa kurang diberi kesempatan melakukansesuatu selain mencatat, mendengar serta menyatakan informasi dengan kalimat mereka sendiri.Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh strategipembelajaran aktif tipe rotating quartet exchange terhadap hasil belajar matematika siswa padaranah kognitif. Jenis penelitian ini yaitu pra eksperimen dan rancangan penelitian yangdigunakan adalah randomized control group only design.Berdasarkan tes akhir hasil belajar diperoleh rata-rata hasil belajar matematika pada kelaseksperimen 83,68 dan rata-rata hasil belajar matematika kelas kontrol 72,13. Hasil analisa uji- t diperolehthitung = 3,58 dan ttabel = 1,67 pada taraf nyata 0,05. Disimpulkan thitung > ttabel menerima hipotesis alternatif(H1) yaitu hasil belajar matematika siswa kelas eksperimen lebih baik dibandingkan kelas kontrol, artinyapembelajaran aktif tipe rotating quartet exchange berpengaruh terhadap hasil belajar siswa.

Abstract

This study aims to examine the influence of taxpayer attitudes, taxpayer awareness, and taxation knowledge on taxpayer compliance in paying rural and urban land and building tax (PBB-P2).  Researchers used quantitative descriptive methods with multiple regression analysis. The population in this study was taxpayers of Cubadak Mentawai Village, Pariaman City and obtained 84 data samples. The data obtained came from questionnaires. Researchers conduct classical assumption tests and hypothesis tests. The results of this study revealed that partially taxpayer attitudes did not significantly affect taxpayer compliance, taxpayer awareness had a significant effect on taxpayer compliance, while taxation knowledge had a significant effect on taxpayer compliance. However, based on the test results simultaneously reveal that taxpayer attitudes, taxpayer awareness, and taxation knowledge have a significant effect on taxpayer compliance.
