Abstract

The characteristics of ash volcanoes can be detected using weather radar by analyzing volcanic ash clouds. Weather radar reflectivity data can describe the estimated height of the column of volcanic ash cloud and the trajectory or direction of the eruption cloud. The BMKG's C-band single-polarization weather radar at Maumere Meteorological Station observed several eruptions of Mount Lewotobi Laki-Laki. Mount Lewotobi Laki-Laki is about 60 km from Maumere Weather Radar, which is still included in the radar coverage. From several eruption events, the eruption activity on 8 November 2024 of Mount Lewotobi Laki-Laki could be observed from the Maumere Weather Radar. The radar data processing produces Maximum (MAX) and VCUT (Vertical Cut) products to obtain information on the height of volcanic eruptions and eruption characteristics in more detail. The MAX and VCUT products of weather radar on the eruption event in this study show that the height of the column of volcanic ash cloud observed by weather radar is higher than the direct observation report by PVMBG.

Abstract

This study aims to analyze the relationship between the revision of Law Number 34 of 2004 and the issue of the return of ABRI's dual function and civil supremacy in the context of Indonesian democracy and reform. The mixed methods approach with SEM PLS-4 and NVivo 12 analysis is used to achieve that goal. The results of the analysis using NVivo 12 showed that ABRI's dwifunction would not return and civil supremacy was maintained because, legally, the TNI remained focused on its role as a tool of national defense. The civil government, through the Parliament and public supervision, has full authority to oversee the TNI so that the TNI still maintains its tested neutrality. The results of the SEM PLS-4 analysis show that the TNI Law's political variable on the issue of ABRI's dual function and civilian supremacy has a statistically significant effect, with a T-statistic value of 5.073 and P-value of 0.000 and a large effect on the model (F-square 0.489). The contribution of this research is to provide an understanding of the importance of a balance between freedom of opinion, politics, and the interests of national defense as a system that supports each other in the post-reform era, as well as in facing the challenges of reform and hybrid warfare towards Indonesia Gold Indonesia 2045. The limitations of this study lie in a limited time, which affects the depth of analysis and data scope so as to limit the perfection of the results of the research as a whole.
