Abstract

Based on Law No. 20 of 2008, MSMEs are referred to as business activities that stand independently in the form of groups or individuals which are not business activities of a branch company. MSMEs play a very important role in the lives of Indonesian people because many Indonesians make a living from selling through MSMEs. There are still many problems that occur in the world of MSMEs in Indonesia, one of which is the lack of product innovation by MSMEs. There are still many MSMEs that only produce food that has spread widely in Indonesia so that the resulting competitive value is very tight between MSMEs. With these problems to help solve the problems faced by MSMEs, a product innovation assistance is held. This assistance is carried out to create a new product innovation in the form of mustard sticks which will later become the newest product in the Fostered MSMEs.

Abstract

The rapid development of technology systems today has triggered a demand for battery development as energy storage. Utilizing the abundant biomass in Indonesia can meet commercial demands, one of which is rice husk. Rice husk is the protective layer that encases rice grains, containing holocellulose (55%), lignin (20%), SiO2 (20%), and minerals (5%), and has the potential to be used as a precursor for silica and carbon to create SiO2@C nanocomposites. In this study, SiO2@C composites were synthesized as lithium battery anode materials from rice husk using a calcination method and the addition of NaOH to form a porous morphology. The calcination process was carried out at 800℃ for 1 hour with a mass ratio of SP-C (Rice Husk Carbonization) and NaOH (1:1, 1:2, and 1:3). The synthesized SiO2@C composites exhibited a porous morphology within the mesopore size range of 13,94 nm at a 1:1 ratio and contained Si 2,42%, O 9,72%, and 87,86%. The mass ratio of NaOH addition can influence the surface area of the SiO2@C composites, with yields of 392,00 m2/g for 1:1 ratio, 1023,04 m2/g for the 1:2 ratio, and 1756,63 m2/g for the 1:3 ratio.
