Analisa Pengaruh Pandemic Covid 19 Terhadap Konsumsi Energi Listrik Di Provinsi Sulawesi Selatan Dengan Metode Regresi Dan Korelasi Linear Sederhana

The level of electricity consumption in an area is affected by population growth and the COVID-19 pandemic. Forecasting electrical energy consumption is one of the important things. Using data from the past, the purpose of forecasting electrical energy consumption is to get an idea of how much electricity will be needed in the future. Therefore, it is necessary to do so in order to forecast the demand for electrical energy, especially in the province of South Sulawesi. This research was conducted to predict electrical energy sold during the 3 years of the Covid-19 pandemic and compare with calculations from PLN and BPS. This study used a simple linear regression method, and a simple linear correlation. With linear regression, it is found that the number of inhabitants has a positive influence on the amount of energy sold. With the T Test obtained RU_t= 18,326 is greater than the limit value of t_cr= 3.182, then Ho = 0 is rejected. So there is a relationship between the increase in population and the consumption of electrical energy. With a linear correlation obtained that between 0.80-1.00 is the value of the correlation coefficient, this means that the correlation is very strong that the population is very influential on the consumption of electrical energy in the province of South Sulawesi

Desain Aplikasi Biaya Sebagai Penetapan Tarif Praktek Bidan Swasta

As long as this fee has not been calculated on a unit cost basis, the rates for midwives differ from one to another, even though they are in the same area. Tariff calculation is only based on the price of goods prevailing in the market. As a result of these differences in rates, people tend to choose private practicing midwives who provide lower rates for the same type of service. The practice of private midwives has not yet calculated the unit cost as the basis for setting tariffs. The purpose is to find out whether the rates currently used are appropriate or not with the unit cost. The data collection technique uses case studies because it only involves one partner unit, namely the midwife. The data collected was then analyzed through descriptive qualitative, namely explaining and explaining the conditions of partners in implementing the excel application regarding practice rates. The location of the community service partner at Midwife Anggraeni Linda Silfyani A.Md.Keb at Babakan Ciparay Bandung. After attending this training, private practice midwives were able to formulate a tariff pattern based on the unit cost that would be used at their practice site. From the explanation above, this dedication to the community is entitled Design Cost Application as the Basis for Determining Tariffs for Private Midwife Practice. From the community service that is carried out, it is hoped that it can minimize problems from partners and become a pilot project for other midwives who have the same problems
