Abstract

Volcanic ash consists of fine particles that are ejected into the atmosphere during an eruption of a volcano. The volcanic ash that will be tested in this study comes from the Aia Angek area of West Sumatra, which erupted in December 2023 to February 2024. The goal of this research was to assess the quantity of montmorillonite found in the volcanic ash originating from Marapi. In order to reach this objective, various examinations were conducted for characterization utilizing XRF, XRD, FTIR and SEM. The XRF data results show that the largest montmorillonite elements in volcanic ash are SiO2 dan Al2O3. The XRD test results show that there are 6 types of montmorillonite contained in Marapi volcanic ash, namely Chlorite-vermiculite-montmorillonite, Montmorillonite (Clay), Illite-Montmorillonite regular, Monmorillonite, Montmorillonite 15-A and Montmorillonite heated. The FTIR test results show that the peak band 3669-467/cm contains the chemical composition of montmorillonite. Based on the SEM test analysis, it shows the morphology of montmorillonite from Marapi volcanic ash with a particle size of 301,9 nm and a porosity size of 151,6 nm. Thus, based on the results of the five characterizations carried out, it is known that the Marapi volcanic ash does contain complex montmorillonite.

Abstract

One of the factors that determines the welfare of a country's people is the Human Development Index (HDI). The aim of this research is to analyze the influence of unemployment, inflation, foreign direct investment and net exports on the Human Development Index in Indonesia. The analysis method used is the Autoregressive Distributed Lag (ARDL) model. The data used is annual data for the 1990-2021 period obtained from the United Nations Development Program and the World Bank. The research results show that unemployment, inflation, foreign direct investment and net exports have a significant effect on HDI in the short term. In the long term, only the unemployment rate has a significant effect on HDI. Net exports have a positive influence on HDI while inflation has a negative impact on HDI in the short term. Current foreign direct investment and current unemployment rate have a positive effect on HDI in the short term. However, the influence of lag one to lag 3 of foreign direct investment  and the unemployment rate on HDI is negative.
