A threshold of 0.1 is selected to analyze the existence and the distribution of deposition of volcanic products such pyroclastic, lava, collapsed lava, and lahars. Geochemical analysis b X-ray fluorescence (XRD) method is used to calculate the soil elements and nutrients originating from volcanic products. The results of SAM mapping and the XRF method are correlated to assess the soil fertility level using the scoring method. Good and very good fertility levels are assessed from the method. After the assessment, a fertility map is generated to calculate the total area of every level. A good fertility level area covers 1164.4 hectares, and a very good level covers 755.52 hectares.Western Java, Indonesia, serves as a vital economic center where millions of people reside, and towering structures dot the landscape. However, this region has endured the devastating impacts of earthquakes in the past. Catastrophic quakes measuring 7.5 and 8.5 in magnitude struck in 1699 and 1780, respectively, resulting in the collapse of numerous homes and substantial loss of life. Despite three centuries elapsing, the existence of another potential earthquake source that could wreak havoc on this particular area remains unknown. To comprehensively assess the prospective seismic hazard that may manifest in the future, it is imperative to identify fault parameters, such as the slip rate and locking depth. The Lembang fault, currently nearing the end of its interseismic cycle, is one such fault under investigation. This research investigates the fault slip rate by leveraging a newly installed GNSS (Global Navigation Satellite System) network situated along the Lembang fault. Complementing this network, InSAR (Interferometric Synthetic Aperture Radar) data will be incorporated for further analysis. These cutting-edge geophysical instruments are indispensable for unraveling the geometry and parameters of this active fault. Moreover, to the best of our knowledge, the joint analysis of GNSS and InSAR data has never been employed in evaluating active faults in Indonesia. By utilizing these collaborative data sources, we demonstrate that the findings of this research can prove invaluable as an input for seismic hazard assessments undertaken by the Government of Indonesia, ultimately contributing to hazard mitigation efforts in western Java.Among abiotic stresses, drought is one of the most important factors limiting plant growth. Most plants interact directly with various microbes to increase their drought tolerance and survival. Local varieties of rice (Oryza sativa L.) are great resources of rice ecotypes that differ from irrigated ecotype rice, it is adapted to both drought-stress and aerobic conditions. However, its root microbial resources have not been explored. Using the omics approach, we aim to describe the microbial community tructure and its functional activity. First, we will characterize the bacteria and fungi from the roots of Local Varieties of Rice from the Banten and West Java Provinces. About ten varieties will be used in this research. Then, the rice roots will be evaluated under well-irrigated and drought-stress conditions. We hypothesized that the genetic diversity from the various ecotypes differed substantially in microbial numbers and bacterial community composition. Furthermore, we would like to observe the microbiota of the soils. Therefore, we expected a variety of supposedly interacting factors, abiotic and biotic likely to affect the microbiota in the rice roots. This study will be carried out by Next-generation sequencing (NGS). NGS technologies have allowed for studying this hidden microbial diversity and functional activity. Furthermore, the microbiota from rice roots under irrigated and drought-stress conditions can serve as effective microbial resources for sustainable agricultural production in Indonesia.84
