Abstract

Penelitian tentang penggunaan karbon aktif dari ampas teh sebagai adsorben telah dilakukan untuk mengadsorpsi -karoten yang terkandung dalam minyak kelapa sawit mentah. Penelitian ini bertujuan untuk mendapatkan model isoterm dan kinetika yang sesuai untuk proses adsorpsi -karoten di dalam CPO. Kajian isoterm dilakukan pada suhu 60C menggunakan rasio karbon aktif terhadap CPO = 1:3, 1:4, 1:5, dan 1:6. Kajian kinetika dilakukan pada suhu 60C, rasio karbon aktif terhadap CPO = 1:3 dimana sampel diambil dengan interval waktu pengambilan 2 menit hingga 120 menit. Hasil penelitian menunjukkan bahwa kemampuan karbon aktif dari ampas teh dalam menyerap -karoten dari CPO ini sangat memuaskan yakni lebih besar dari 99%. Persentase adsorpsi -karoten terbaik diperoleh pada rasio karbon aktif terhadap CPO = 1:3, yakni sebesar 99,61%. Model isoterm yang sesuai dengan data penelitian ini adalah model isoterm Freundlich. Sedangkan model kinetika yang sesuai adalah orde dua semu dengan nilai koefisien korelasi (R2) sebesar 0,996. Berdasarkan model kinetika tersebut diketahui bahwa laju penyerapan pada kesetimbangan adalah sebesar 3,5087 mg/g dan konstanta laju adsorpsi sebesar 0,0578 (L/menit).

Abstract

This research aims to determine the effect of Return on Equity (ROE), Current Ratio (CR), Debt to Equity Ratio (DER), & Earning per Share (EPS) on Share Prices of Mining Companies in the Coal Mining Sub-Sector Listed on the Indonesia Stock Exchange in 2016-2020 either partially or simultaneously. The number of samples used in this study were 8 coal mining sub-sector companies listed on the Indonesia Stock Exchange from a total population of 28 companies. The type of data is secondary data sourced from the company's financial statements and annual reports. The data analysis method used is multiple linear regression analysis. The results of hypothesis testing in this research indicate that simultaneously Return on Equity (ROE), Current Ratio (CR), Debt to Equity Ratio (DER), & Earning per Share (EPS) have no significant effect on stock prices. Partially, Return on Equity (ROE) has an effect on stock prices. Meanwhile, Current Ratio (CR), Debt to Equity Ratio (DER), & Earning per Share (EPS) have no effect on stock prices.

Abstract

This study uses primary data with quantitative descriptive. The data used in this study is in the form of questionnaires to 52 employees. The sampling technique is the same as the total population at PT. Enseval Putera Megatrading, Tbk Pangkalpinang Branch. The data analysis method used is descriptive statistics with hypothesis testing using multiple linear regression processed with JASP. The results of the study show (1) Control Environment has no partial effect on employee performance with a significance value of 0.813. (2) Risk assessment has no partial effect on employee performance with a significance value of 0.239. (3) Control activities have no partial effect on employee performance with a significance value of 0.230. (4) Information and Communication has no partial effect on employee performance with a significance value of 0.968. (5) Monitoring has a partial effect on employee performance with a significance value of 0.020. (6) Control Environment, Risk Assessment, Control Activities, Information and Communication and Monitoring have a simultaneous effect with a significance value of 0.001.

Abstract

This research was entitled: “Analisis Pengaruh Kualitas Pelayanan, Lokasi, Harga service Terhadap Kepuasan Pelanggan di Bengkel Motor Coms”. The purpose of this study was to determine the effect of direct marketing on purchasing decisions either simultaneously or partially. This research was conducted from January 2023 to June 2023. The method used in this study is descriptive with a quantitative approach with the aim of finding the relationship between the independent variables (Service Quality, Location, Service Price.) and the dependent variable (Customer Statisfaction) using a statistical formula. While the statistical formula used to test the hypothesis of Multiple Linear Analysis. The sample in this study amounted to 94 people. The results of the study prove that: (1) Service quality has an effect on Customer Statisfaction,tcount value is 2.704 greater than the ttable 1.98667.(2) Location does not affect Customer Statisfaction value of tcount -1523 is smaller than ttable 1.98667. (3) Service price has an effect on Customer Statisfaction,tcount value is 3.470 greater than the ttable 1.98667.

Abstract

The method used in this research is a descriptive method with a quantitative approach to find the relationship between the independent variables (service quality, corporate image, and satisfaction) with the dependent variable (loyalty) using statistical formulas. While the statistical formula used to test the hypothesis is multiple linear regression analysis, the sample in this study amounted to 67 people. The test results for the service quality variable (X1) where tcount (4.486) > ttable (1.669) mean that the service quality variable (X1) has a partial effect on loyalty (Y). The test results for the company image variable (X2) where tcount (-0.221) < ttable (1.669) mean that the corporate image variable (X2) has no partial effect on loyalty (Y). The test results for the satisfaction variable (X3) where tcount (7.121) > ttable (1.669) mean that the price variable (X3) has a partial effect on loyalty (Y).

Abstract

This research aims to find out how big the role of the Online Financial System (SISKEUDES) is in improving the quality of village financial accountability in Benteng Village, Pangkalan Baru District, Central Bangka Regency. The research method used in this research is qualitative with data collection techniques obtained from interviews and documentation. There were 4 informants in this research, namely the Village Head, Village Secretary, Finance Head and Planning Head. From the results obtained during the research, it can be concluded that the presence of SISKEUDES in Benteng Village helps the village accountability process to the local government and community with the village financial reports produced by this application. Then regarding the accountability of village financial reports, judging from the vertical and horizontal accountability indicators, the reporting and accountability of the Benteng Village Government has been said to be good or accountable. Benteng Village has implemented SISKEUDES which is adapted to Permendagri No. 20 of 2018 concerning Village Financial Accounting so that the quality of reporting can be accounted for based on applicable village accounting. Although there are still problems with the application which often causes errors.
