Abstract

Vanilla is one of the spices that has many benefits and a fantastic price. The high world demand for vanilla makes the competitiveness between exporters tighter. Each exporter tries to maintain the quality of their vanilla and the destination country market. In addition, other factors can affect vanilla exports from each exporter to the destination country. This study aims to determine the level of competitiveness and factors that affect the value of vanilla exports from Indonesia to destination countries. The method in this study uses ECI and panel data regression analysis. The results of the average ECI value show that vanilla from Indonesia has a strong competitiveness index in its export destination countries including China, India, the United States, the Netherlands and Thailand. This can be seen from the average value of ECI > 1. Factors that affect the value of Indonesian vanilla exports are the exchange rate of the rupiah against the United States dollar and the volume of Indonesian vanilla exports to destination countries which have a positive and significant effect. The population of the destination country and the GDP per capita of the destination country have a positive and insignificant effect. The covid 19 pandemic dummy has a negative and insignificant effect.

Abstract

This research is conducted using 4 lines data with 750 meters in length. Tomography resistivity with Wenner-Schlumberger configuration is used as this research methodology to take the data with a = 50 meters and n=1, 2, 3, 4, 5, 6. Resistivitymeter OYO 2119C McOHM-ELmodel is used as the instrument. Furthermore, the data is processed with two softwares; Res2Dinv ver. 3.56.22 to get 2D resistivity section and RockWork16to make 3D model of the site. The underground river’s chamber is made by hollow carbonate rocks with the resistivity of >412 Ωmand 117,6 Ωm – 412 Ωm for limestone’s resistivity as its capsrock. Researching to the depth of 173 meters, underground rivers are shown in the line 2 in the depth of 65 to 134 meters, 65 to 173 meters in the line 3, and in the cross section of line 3 and line 4. While in the first trajectory, another chamber is found within the depth of 12.5 to 40 meters. It is expected that the underground river is flowing to the south because of the chamber in third and fourth trajectory are lower than second trajectory.
