“…The particle size distribution composition at the four research sites was dominated by sand, while the clay was the lowest fraction of soil. This is similar with the study conducted by Wardoyo and Santosa (2016), which shows that sand has the highest fraction (82.35%) followed by silt (8.78%) and clay (1.62%).…”

Vegetation recovery is essential in land restoration after the eruption of Mount Merapi in 2010. Vegetation is a source of organic material that produces root exudate containing organic acids. These acids accelerate the dissolution process of volcanic material so that it affects the soil characteristics. This study was conducted to analyze the effect of four types of perennial plants on soil chemical and physical characteristics. The soil samples were taken on the area planted with cinnamon,

“…Concerning local wisdom possessed by farmers in reclaiming land affected by volcanic eruptions, Ishaq et al (2020) reported that the practice of farmers in reclaiming land after the eruption of Mount Kelud was carried out by mixing volcanic ash with mineral soil underneath by hoeing and adding organic fertilizer (chicken manure or crop residues) and inorganic fertilizers (urea or NPK). In addition, Wardoyo & Santoso (2016) had proven that the use of organic matter as a nitrogen fertilizer improved the growth of Canavalia virosa and Flemingia congesta cultivated in the sandy ash soil of Mount Merapi.…”

Journal of Agricultural Science www.agrivita.ub.ac.id This eruption also damaged some regions in the Cangkringan district Sleman Regency. Moreover, Iguchi, Ishihara, Surono, & Hendrasto (2011) reported that the eruption that occurred on October 26 th , 2010, damaged the mountain cliff (dome) formed in 2006. More significant destruction was recorded from the eruptions on November 3 rd and 5 th, 2010, as the opened cliffs emitted the flow of pyroclastic materials and ash. The volcanic eruption was followed by pyroclastic flows, surges, debris avalanches, and lahars, which could damage the ecosystem, plantation, and settlements (Kadavi, Lee, & Lee, 2017; Sadono, Hartono, Machfoedz, & Setiaji, 2017). Its adverse effects may lead to forest degradation (vegetation loss), the decline of land fertility (an increase of damaged lands), and disruption of the local water cycle (streamflow, water table, and available water) (

Volcanic material sedimentation of Mt. Merapi causes changes in surface soil's physical and chemical properties that reduce soil fertility. The eruption of the mountain also builds volcanic soil layers, which are generally porous and have a low water-holding capacity. The chemical properties of this layer have low nutrient content and organic matter. Solid human feces composted for 30 days has a water content of 51.62%, carbon 15.62%, nitrogen 1.50%, and phosphorus 6.45%. The potential of nutrients possessed by human feces compost has the opportunity to be used as a source of fertilizer for plants because the plant, animal biomass, and human excreta are essential components of material and energy flow in ecosystems. However, the human feces compost as an organic fertilizer has not yet been widely utilized. Therefore, the research aims are to study the potential of sanitized human feces composts to improve the fertility of volcanic soil from Mt. Merapi Indonesia and find its optimum dosage for sweet corn cultivation. Volcanic soil from Mt Merapi was brought to the greenhouse from the mountain area and used as media to cultivate sweet corn plants. The research was conducted using a completely randomized design (CRD) with five treatments consisting of four dosages of human feces compost and one control treatment using cattle manure. The four dosages of composted human feces were applied in the volcanic soil with the dose of 5, 10, 15, and 20 tons/hectare. Organic fertilizer from cattle manure with a dose of 20 tons/hectare was used as a control. The result showed that human feces compost has similar potential as cattle manure (control treatment) in increasing the growth and yield of sweet corn. Furthermore, the result also showed that the optimum dosage of organic fertilizer from human feces compost to increase sweet corn's productivity was 15 tons per hectare.
