“…This indicated that the environmental conditions of Location I and II were not much different, while the environmental conditions between Location I and Location IV were very different because Location IV was covered with volcanic ash with > 5 cm thickness, which can affect soil temperature, humidity, and pH. Research results by Simbolon et al (2018), Sinaga et al (2015), Zebua et al (2020), andQadaryanty et al (2020) indicated that the thicker volcanic ash covering the soil surface, then soil pH, C-organic, and soil moisture will decrease. If soil moisture and the availability of organic matter in the soil decrease, soil organisms can die or migrate, thus affecting the diversity of soil fauna in the area.…”

Abstract. Sembiring M, Munawaroh H, Mukhlis, Hidayat B, Sabrina T. 2021. Soil macrofauna diversity in andisol after eight years of Mount Sinabung eruption in Sumatra, Indonesia. Biodiversitas 22: 3024-3030. The eruption of Mount Sinabung resulted in volcanic ash covering the soil of various thicknesses. That will affect the population and diversity of macrofauna in it. This research aimed to determine the Andisol soil macrofauna in Karo District with various thicknesses of volcanic ash covering from Mount Sinabung. This research was conducted in May 2019. Plots were placed in four locations, Location I: processed land (0 cm), Location II: Land covered by thin ash (?2 cm), Location III: Land covered by medium ash (2-5 cm), Location IV: Land covered by thick ash (?5 cm). Sampling was conducted by using the Pitfall trap, Monolith squared, and Hand sorting methods. The research results indicated that the thicker the volcanic ash covering the soil surface, it would reduce soil moisture, soil water content, organic C, and soil pH, but on the other hand, increase the soil temperature. A total of 20 species were able to live on the Andisols affected by the eruption of Mount Sinabung.

“…The sulphur released during the eruption originates from sulphur-bearing components in magma [9]. This SO3 affects the pH value of pyroclastic materials and volcanic soils [20,21], and over time it will become the source of available soil nutrients [22]. Pyroclastic materials have various types of mineral content [16], largely controlled by the composition of magma, temperature, pressure, and magma chamber during the crystallization process [17,18].…”

Sulphur dioxide (SO2) emissions from Mt. Sinabung eruption were quantified in time series for 2019. Both pyroclastic materials and gas or aerosol ejected during volcanic eruption contain sulphur as sulphate salt deposits coating volcanic ash grains or gasses. Sulphur dioxide from the eruption will directly impact the surrounding area. Spectral from satellite optical sensors can be used to monitor and measure SO2 gas near real-time after an eruption. The distribution of SO2 column density in the atmosphere was tracked using the Sentinel-5P satellite. Regression kriging (RK) is applied to predict the spatial distribution of sulphur. The area under study is located in a radius of 3 to 7 km from the eruptive center, covering an area of about 4,517 ha. A total of 51 soil samples and volcanic ash were collected from 0- 20 cm soil depth based on a 1x1 km grid interval. All samples were air- dried, sieved, and analyzed for pH, sulphate, and total SO3 using XRF. The Google Earth Engine (GEE) platform was also used to process Sentinel-5P satellite imagery to determine the number and distribution of SO2 column density in the atmosphere during 2019. The pH of the ash is very acidic to neutral (3.56 - 6.55), while soils are considered acidic to neutral (4.67 - 6.52). The available sulphate content in soil ranges from 0 to 303.39 ppm and 0 to 142.47 ppm in volcanic ash samples. SO2 content in ash ranges from 0 to 16.53% and 0 to 3.71% in soils. Sentinel-5P satellite image spectral data shows that SO2 is concentrated mainly in the southern region, with the highest level occurring in August 2019. This study can serve as one of the volcanic mitigation programs and forecast the distribution of SO2 in an active volcanic region of Indonesia.

Background and Objective: The availability of Nitrogen (N) is very limited in the soil because this nutrient is easily washed and evaporates so that it cannot be absorbed by plants. Efforts that can be made to increase the availability of N in the soil is to utilize non-symbiotic N-fixing bacteria. The purpose of this study was to obtain superior microbes that could increase the efficiency of N fertilization and the growth of corn in Andisol soil. Materials and Methods: The materials used in this study were Andisol soil, Dyella japonica, Enterobacter cloacae. The study applies a factorial randomized block design consisting of 2 factors. The factor I is nitrogen-fixing bacteria consisting of 4 treatments, no bacteria (N 0 ), D. japonica 5 g/plant (N 1 ), E. cloacae 5 g/plant ( N 2 ) and D. japonica 2.5 g+E. cloacae 2.5 g (N 3
