      Abstract
      Penelitian ini bertujuan untuk menganalisis ketergantungan nilai tukar IDR-USD terhadap volume ekspor pertambangan di Indonesia dengan menggunakan pendekatan copula. Ketergantungan ini penting untuk dipahami mengingat nilai tukar dan ekspor mineral berdampak langsung terhadap perekonomian negara yang bergantung pada devisa dari sektor ini. Ekspor mineral merupakan salah satu sumber devisa utama negara, sedangkan nilai tukar memengaruhi daya saing ekspor di pasar internasional. Produk pertambangan yang diambil adalah besi dan baja, tembaga, nikel, dan alumunium yang merupakan komoditas unggulan Indonesia. Metode copula dipilih karena kemampuannya untuk menangkap dan memodelkan ketergantungan non-linier antar variabel, tanpa mempertimbangkan distribusi masing-masing variabel. Copula memungkinkan untuk memodelkan distribusi marjinal nilai tukar dan volume ekspor secara terpisah dari struktur ketergantungannya, yang sejalan dengan sifat ekonomi sektor pertambangan Indonesia yang kompleks dan dinamis. Hasil penelitian menunjukkan bahwa tidak terdapat ketergantungan yang signifikan antara nilai tukar dengan volume ekspor komoditas yang diambil. Oleh karena itu, kebijakan volume ekspor komoditas ini tidak akan memberikan pengaruh yang signifikan terhadap fluktuasi nilai tukar IDR-USD dan sebaliknya. Artikel ini dapat menjadi rekomendasi bagi eksportir untuk memahami bahwa volume ekspor tidak perlu memperhatikan fluktuasi nilai tukar.
       
      This study aims to analyze the dependence of the IDR-USD exchange rate on the volume of mining exports in Indonesia using the copula approach. This dependence is important to understand considering that the exchange rate and mineral exports have a direct impact on the country's economy which depends on foreign exchange from this sector. Mineral exports are one of the country's main sources of foreign exchange, while the exchange rate affects export competitiveness in the international market. The mining products taken are iron and steel, copper, nickel, and aluminum which are Indonesia's leading commodities. The copula method was chosen because of its ability to capture and model non-linear dependencies between variables, without considering the distribution of each variable. Copula allows for modeling the marginal distribution of the exchange rate and export volume separately from its dependency structure, which is in line with the complex and dynamic nature of the Indonesian mining sector economy. The results of the study indicate that there is no significant dependence between the exchange rate and the export volume of the commodities taken. Therefore, the export volume policy for this commodity will not have a significant effect on the fluctuation of the IDR-USD exchange rate and vice versa. This article can be a recommendation for exporters to understand that export volume does not need to pay attention to exchange rate fluctuations.
