Abstract

The problems that are generally found in land preparation for infrastructure developments are the characteristics of soils that have low bearing capacity, such as peat soils. Calcite precipitation is a soil improvement method that utilizes biochemical reactions with the final product being calcite. Peat soil has different characteristics from other soils, that it has high levels of Dissolved Organic Carbon (DOC). The amount of DOC present in peat soil significantly affects the specific gravity, liquid limit, density, and strength of the soil. Therefore, it is necessary to evaluate whether DOC in peat soil can affect the effectiveness of the calcite precipitation method. The research was conducted on soil with high organic content (95.35%) and soil with moderate organic content (73,51%). The research was carried out through five stages, namely soil properties, test-tube experiment, soil samples treatment, Unconfined Compressive Strength (UCS) test, and evaluating the soil pH. The results of this study obtained in the form of high organic content have an additional strength of 76.47%. Medium organic content soil has an additional strength of 137.50. Thus, DOC has an effect on increasing soil strength in the calcite precipitation method.

Abstract

New normal is a government policy that must be implemented in everyday life, including in the life of the people on Cendana Village, Banjarnegara Sub-District, Banjarnegara Regency, Central Java. The spread of COVID-19 has also affected various sectors of social life from economy, politics, social, and culture. This activity aims at public awareness to apply the new normal protocol, support the food needs of the community during pandemic by utilizing residents yard, and increase the selling value of the crops produced by residents with simple innovations from home. This activity was carried out on 8-18 August 2020. The results obtained were an increase in knowledge of COVID-19 and the application of a new normal protocol based on the results of the pre-test and post-test, the formulation of the “Lintang Asri” Farmer Woman Group at Dukuh Lintang Tiba, Cendana Village, 37and the direct application of the knowledge obtained after the socialization and demonstration of agriculture product innovation by several residents in Cendana Village. Keywords: community movement, yields, yard
