Tujuan penelitian adalah untuk mengetahui efikasi diri terhadap prokrastinasi akademik di SMK Islam Ruhama. Metode penelitian yang digunakan dalam penelitian ini adalah metode kuantitatif. Sumber data yang digunakan adalah peserta didik kelas XII di SMK Islam Ruhama dengan responden sebanyak 42 peserta didik. Teknik dalam pengumpulan data yang digunakan dalam penelitian ini adalah menggunakan kuisioner (angket). Dari hasil perhitungan nilai korelasi product moment sebesar r = 0,802 berada dalam skala yang sangat kuat dan perhitungan koefisien determinasi yang hanya memberikan kontribusi efikasi diri terhadap prokrastinasi akademik sebesar 74,20%. Kemudian hasil dari pengujian hipotesis menunjukkan nilai - thitung < -ttabel atau -5,110 < -2,021 maka Ho berada di daerah penolakan. Hal ini menunjukkan bahwa Ho ditolak, dengan demikian Ha diterima, sehingga dapat disimpulkan terdapat pengaruh efikasi diri terhadap prokrastinasi akademik.

Penelitian ini bertujuan untuk mengetahui adanya pengaruh yang signifikan konsep diri Guru terhadap kinerja Guru di SD Negeri Sawah 2 Ciputat. Metode penelitian yang digunakan dalam penelitian ini adalah metode kuantitatif. Sumber data yang digunakan adalah Guru di Sekolah Dasar Negeri Sawah 2 Ciputat dengan responden sebanyak 32 Guru. Teknik dalam pengumpulan data yang digunakan dalam penelitian ini adalah menggunakan kuesioner (angket). Dari hasil perhitungan nilai korelasi product moment sebesar r = 0,527 berada dalam skala yang sedang dan perhitungan koefisien determinasi yang hanya memberikan kontribusi konsep diri terhadap kinerja Guru hanya sebesar 27,80 %. Kemudian hasil dari pengujian hipotesis menunjukkan nilai t hitung > t tabel atau 2,461 > 1,695. Sehingga disimpulkan bahwa terdapat pengaruh yang sangat signifikan konsep diri terhadap kinerja Guru di Sekolah Dasar Negeri Sawah 2 Ciputat. Kata kunci : konsep diri Guru, kinerja Guru

The purpose of this study was to determine the simultaneous effect of the inflation rate, interest rates and economic growth on the rupia exchange rate. This study also examines the partial effect of the inflation rate on the rupia exchange rate, finds the effect of interest rates on the rupia exchange rate, and economic growth on the rupia exchange rate. The research method used in this study is a quantitative method. The data source used is secondary data in the form of a Time Series. Time-series data is data that is collected over a specified period / period of time. The data collection technique used in this research is the documentary method taken from the Central Bureau of Statistic's data. From the calculation of the F value it is known that 0.00467 < 0.050, so there is a simultaneous influence of the inflation rate, interest rate and economic growth variables on the Rupiah exchange rate. The regression equation is Y = . The inflation rate coefficient for variable X1 is 0.009 and positive. This shows that the inflation rate has a direct relationship with the Rupiah exchange rate. This means that every time one unit of inflation increases, the beta variable (Y) of the rupia exchange rate will also increase by 0.009 with the assumption that other independent variables from the regression model have been corrected. The value of the interest rate coefficient for variable X2 is -0.02 and is negative. This indicates that the interest rate has a direct relationship with the Rupiah exchange rate. This means that each time the interest rate increases by one unit, the beta (Y) variable of the rupia exchange rate will decrease by 0.02 assuming that the other independent variables of the regression model have been corrected. If the value of economic growth (X3) increases one point, then the Y value will decrease by 0.06, assuming that the other independent variables of the regression model are fixed.Keywords: Inflation rate, interest rate, economic growth, rupia exchange rate

Unemployment occurs because of an imbalance in the labor market. The labor demand curve shows the number of workers employed by firms and has a negative slope at a certain wage level, while the labor supply curve shows the amount of labor that households will supply and has a positive slope to wages. The research objective was to determine the effect of the Human Development Index (HDI) on the unemployment rate in Indonesia in 2010-2019. The method used in this research is time-series data analysis method with quantitative methods. In this study, the results show that the relationship between the Human Development Index (HDI) and the unemployment rate is 0.960, which means that it has a very strong relationship. The influence of the contribution of the Human Development Index (HDI) variable in the unemployment rate is 82.1%. The Human Development Index (HDI) has a significant and negative effect at the 5% level on the unemployment rate. This is evidenced by a significance value.
