Abstract

In the current digital era, the emergence of technology and high business competition makes MSMEs compete with their competitors. Conventional marketing strategies are no longer enough to win the competition. Unfortunately, there are still many MSMEs that have not been able to optimize digital platforms as a marketing tool, especially MSMEs in Banjarsari Village. Therefore, Group 3 KKN students prepared a work program for Micro, Small and Medium Enterprise Development in Banjarsari Village. The aim is to provide assistance and assistance as well as understanding the importance of digital marketing to expand market reach. The results achieved are that MSMEs in Banjarsari Village have an Online Shop as a means of marketing products online and facilitating communication and transactions with consumers.

Abstract

Ottawa sand is a type of sand widely used in geotechnical research for its uniformity and high silica content. However, Ottawa sand is classified as a non-cohesive soil, lacking intergranular bonds, resulting in low shear strength. Therefore, a soil improvement method that enhances the material's mechanical stability is needed. This study aims to analyze the effect of Ottawa sand pretreatment on increasing soil shear strength through a bio-stabilization method using the fungus Rhizopus oligosporus. The research method used is a laboratory experimental method with an unconfined compression test. Ottawa sand samples were divided into three treatments: normal treatment (S-0), washed sand treatment (S-1), and washed and oven-dried treatment (S-2). Each sample was mixed with tempeh yeast containing Rhizopus oligosporus and distilled water, each at 5% of the sand weight. The curing process was conducted in a closed container, with temperature, humidity, and mycelium development monitored during incubation. The results showed that sand pretreatment increased the soil's unconfined compressive strength. The samples treated with washing and oven drying (S-2) had the highest unconfined compressive strength of 9.72 kPa and shear strength of 4.86 kPa at 12 days of curing. Meanwhile, the samples without pretreatment showed lower unconfined compressive strengths. Visually observed mycelial growth showed a more even distribution in the samples with sand pretreatment. The results of this study indicate that bio-stabilization using Rhizopus oligosporus has the potential to be a more environmentally friendly soil-improvement method for increasing the stability of sandy soil.
