Abstract

This research was conducted based on the low number of tax employees in helping taxpayers carry out their tax obligations. This results in some taxpayers using the services of tax consultants. Taxpayers expect tax consultants to be able to help and solve tax problems that are being pursued by taxpayers. The purpose of this study is to foresee the use of services in the coming month at the tax consultant's office Rahmat Accountax. The method used in this study is a quantitative method. The data is processed in the form of quantitative data in the form of months, years, and the number of people who use services at the Rahmat Accountax office in January 2020-March 2022. This research is to predict the development of service use with the Single Exponential Smoothing (SES) method. The Single Exponential Smoothing method is a method used in short-term forecasting that is usually only 1 month ahead which assumes that the data fluctuates around a fixed mean value without a trend or consistent growth pattern. From the analysis that has been carried out, the author can conclude that the forecasting of service use at Rahmat Accountax has decreased from the previous month, namely as many as 8 clients to 7 clients with α=0,2

Abstract

Koi fish (Cyprinus carpio) is one of the most popular ornamental fish with high economic value and can compete in local and international markets. One of the obstacles in koi fish farming is growth and survival caused by changes in temperature. One of the factors that affect temperature changes is water level. This study aims to determine the effect of water level on the growth and survival of koi fish seeds. This study used an experimental method with a completely randomized design (CRD). There were 4 (four) treatments tested, namely P1 (15 cm) as control, P2 (20 cm), P3 (25 cm), and P4 (30 cm). Each treatment was repeated 3 times, resulting in 12 experimental units. The variables taken were fish length and weight, and water quality (temperature, pH, DO, ammonia). The results showed that. The ideal container water level and can provide the best results to support the growth of koi fish fry is 25 cm. At a water level of 25 cm, weight growth of 0.034 grams/day, length growth of 0.018 cm/day, specific growth rate of 0.021%/day, and survival rate reached 100%. Meanwhile, water quality parameters during the study were in the optimal range, namely temperature 19 - 23 °C, pH 7, dissolved oxygen 5 - 8 mg/L, and ammonia 00.1 - 0.06 mg/L.

Abstract

The field of mathematics is a scientific discipline that can solve economic problems. This is because the field of mathematics can be used in dealing with financial audit problems that use images and numerical ideas in critical thinking. Apart from that, branches of mathematics such as the application of systems of linear equations can influence economics. Therefore, this research is intended to find out in more depth about the Application of Systems of Linear Equations in Economics. The aim of this research is to find the effect of implementing systems of linear equations in economics. To achieve this goal, the author uses library research methods with the aim of collecting data or information with the help of technology in the form of computers and various sources in libraries such as books, journals, articles and similar research results. From this research, several explanations regarding the Application of Systems of Linear Equations which can influence the field of Economics are produced, including: 1). The application of the Linear Equation system can influence Demand in the economic sector; 2). The application of the Linear Equation system can influence supply in the economic sector; 3). Application of a Linear Equation System can result in market balance (market equilibrium); 4). Implementation of a Linear Equation System can affect Tax; 5). Application of the Linear Equation System can affect subsidies. From the research conducted, the author hopes that it will become a reference in the world of economics and become a reference in carrying out efforts to improve the economy.

Abstract

This research aims to determine the application of linear function concept in economics and business. A linear function is the simplest function because it only has one independent variable and has a power of one. This research is qualitative research that uses a literature study method with an exploratory approach. Data collection techniques are carried out by collecting valid secondary data sources from books, scientific journals and the internet. The research results show several linear function models, namely the demand function Qdx = -a.Pdx +b , the supply function Qsx = a.Psx +b , the market balance point from the linear equation Pdx = Psx , the consumption function C = C0 + cY , the savings function S = C0 + (1 - c ) Y, and the production cost function TC = TFC + TVC.

Abstract

This research aims to explore the learning trajectory of data analysis in the Fase A class using the case study or action research method in the context of traditional food from cassava with the PMRI (Indonesian Realistic Mathematics Education) approach. The focus of this research is on the diversity of traditional foods made from cassava. The research method used is action research which involves Fase A class students in understanding and analyzing data related to traditional food that uses cassava as the main ingredient. Through the PMRI approach, students are encouraged to understand not only the mathematical aspects of the data, but also the cultural aspects and local wisdom related to the food. The results of this research indicate that by applying PMRI in teaching, students can be more actively involved in collecting, analyzing and interpreting data about traditional cassava food. They learn how to convert quantitative information into a deeper qualitative understanding of the rich culture around them
