Abstract

Economic growth is a difficult problem for every country to overcome. The government can use macroeconomic policies, namely monetary policy and fiscal policy, to increase economic growth. The monetary policy instruments used in this research are JUB, BI rate, inflation and exchange rate, while fiscal policy is in the form of taxes and government spending. By using the VAR method, JUB and the exchange rate have a significant influence on economic growth and in the long term increasing JUB and stabilizing the exchange rate can increase economic growth while high inflation and BI rates can reduce economic growth. When the economy is sluggish, the government can increase the JUB by reducing the Minimum Statutory Reserve and carrying out open market operations, limiting imports and increasing exports so that the rupiah exchange rate against the dollar can appreciate so that inflation can be suppressed, then lowering the interest rate on savings and loans so that people can running MSMEs or macro businesses. In the long term, fiscal policy in increasing tax revenues from the formal sector and increasing government spending in infrastructure development, education and health can increase economic growth.

Abstract

Indonesia's tobacco exports are currently experiencing a setback. For this reason, this research uses the ARDL (Autoregressive Distributed Lag) model with variables of production, land area, international prices and exchange rates which influence Indonesian Tobacco Exports both in the short and long term. For the short term, the ARDL model forecasting variables for production, land area, international prices and exchange rates have a significant effect on Indonesian tobacco exports, while for the long term the variables of international prices and exchange rates have a significant effect on Indonesian tobacco exports.

Abstract

This research aims to estimate the expenditure on Toba Batak wedding customs from the initial stages to the traditional wedding ceremony by taking an inventory of various expenditures so that the economic value of the wedding custom can be mapped. The economic value referred to is the value paid by consumers (namely paranak and parboru) for goods and services purchased or consumed or used in marriage customs, especially from micro, small and medium enterprises (MSMEs). To collect data, 30 families were selected as research samples with the following criteria: (1) the traditional wedding party was paid for by paranak , (2) the amount of the dowry (sinamot ) was a maximum of 40 million rupiah, (3) the martumpol was held , (4) the traditional party was held in Medan , and (5) paranak and parboru are both Toba Batak people. The sampling method is accidental sampling and data collection starts from March to August 2023. Then the primary data is processed using simple mathematical calculations and analyzed quantitatively descriptively. The research results show a total expenditure of 2,833,900,000 rupiah or an average of 188,926,667 rupiah for each wedding custom. The main source of expenditure is paranak, almost 69% of the total. Meanwhile, the economic value of traditional marriages reached 1,965,600,000 rupiah or an average of 131,040,000 rupiah, namely to pay for goods and service transactions to MSMEs. Paranak contribution to the transaction was around 67% and the rest came from parboru. Assuming 500 marriage customs, the economic value of marriage customs is estimated to reach hundreds of billions in 2023 and become one of the drivers of economic activity, especially for MSMEs in Medan City.

Abstract

This study aims to analyze the effect of export volume, rupiah exchange rate, and inflation on Indonesia’s foreign exchange reserves during the period 2000–2023. The data used are secondary data obtained from the Central Bureau of Statistics (BPS) and Bank Indonesia (BI). The analysis was conducted using multiple linear regression with the EViews 12 software. The results show that export volume and the rupiah exchange rate have a positive and significant effect on foreign exchange reserves, while inflation has a negative and significant effect. The coefficient of determination (R²) of 0.9462 indicates that the three independent variables explain 94.62% of the variation in Indonesia’s foreign exchange reserves, while the remainder is influenced by other factors outside the model. These findings highlight that increasing exports and maintaining exchange rate stability strengthen foreign exchange reserves, whereas high inflation weakens them. Therefore, controlling inflation and enhancing exports are crucial strategies for sustaining Indonesia’s foreign exchange reserve stability.

Abstract

This study analyzes the influence of exchange rates, inflation, and interest rates on shrimp exports in Indonesia from 1999 to 2019 using multiple linear regression. The research findings indicate that the exchange rate and inflation positively influence shrimp exports, whereas the interest rate negatively impacts them. The regression coefficient for the exchange rate is 10.015, which indicates that each depreciation of the rupiah by 1 rupiah per year will increase shrimp exports by 10.015 tons per year. Conversely, the interest rate has a negative regression coefficient of -3519.690, suggesting that each 1% increase in interest rates will reduce shrimp exports by 3.519,690 tons per year. Inflation has a positive regression coefficient of 3.333,168, indicating that each 1% increase in inflation will increase shrimp exports by 3.333,168 tons per year. However, only the exchange rate shows a significant relationship, with inflation and interest rates not significantly impacting shrimp exports. The model's coefficient of determination is 58.3%, meaning that approximately 58.3% of the variation in shrimp exports can be explained by the exchange rate, inflation, and interest rates. This study provides crucial insights for policy makers and the shrimp industry in considering the factors affecting shrimp exports for the creation of applicable policies and strategies.

Abstract

Tujuan: Penelitian ini bertujuan untuk menganalisis pengaruh pelatihan dan motivasi terhadap kinerja, baik secara langsung maupun melalui variabel mediasi disiplin kerja. Metode Penelitian: Jenis penelitian ini adalah kuantitatif dengan metode pengumpulan data melalui kuesioner dan observasi awal. Data dianalisis menggunakan metode Partial Least Square (PLS). Hasil dan Pembahasan: Hasil penelitian menunjukkan bahwa: (1) pelatihan berpengaruh positif dan signifikan terhadap kinerja, (2) motivasi berpengaruh negatif dan tidak signifikan terhadap kinerja, (3) pelatihan dan motivasi masing-masing berpengaruh positif dan signifikan terhadap disiplin kerja, (4) disiplin kerja berpengaruh positif namun tidak signifikan terhadap kinerja, serta (5) disiplin kerja tidak berperan sebagai variabel mediasi antara pelatihan dan motivasi terhadap kinerja pegawai. Implikasi: Temuan ini menunjukkan bahwa meskipun pelatihan dan motivasi dapat meningkatkan disiplin, disiplin tidak secara langsung memediasi peningkatan kinerja pegawai.
