Abstract

Soil or subgrade is the place where the construction made by technicians for personal and collective interests stands. Before starting a construction, soils that have low bearing capacity, water absorption and high plasticity can be stabilised by soil stabilisation methods. Soil stabilization may involve the use of chemical stabilization materials. This research aims to determine the effect and get the appropriate comparison of the results of the addition of a mixture of fly ash, bottom ash and silica. This research study was conducted using soil samples from Kalianda subdistrict and stabilization materials in the form of fly ash, bottom ash and silica matured for 24 hours. Tests were conducted at the Soil Mechanics Laboratory and physical and mechanical properties were tested.. Clay soils classified as A-7-5 (AASHTO) and OH (USCS) mixed with 4 different compositions of stabilising materials had different results. Of the 4 compositions, the mixture that has the largest bearing capacity value is only silica. Because the results of the CBR test on the mixture that added silica were greater than the mixture using only fly ash and bottom ash. Fly ash, bottom ash and silica gel are easily found or affordable, but the use of silica can increase costs due to its relatively expensive price, inversely proportional to the very affordable price of fly ash and bottom ash.

Abstract

The Women's Farmers Group serves as a platform for the community, particularly women,to manage and express various ideas in the field of agriculture as well as a way for group members tolearn and gain perspective. As a result, group activities are expected to be imaginative and up-to-date.The Makmur Jaya Women's Farmers Group has performed a number of functions that have benefitedthe community, including serving as a venue for learning through ordinary activities, training suppliedas a discourse of cooperation in welfare efforts for the community, and fostering creativity to increaseincome. Producing several types of traditional Lampung skullcaps as part of this activity would helpmembers of the Makmur Jaya women's farmer group to promote and enhance their creativity. Bycreating several styles of traditional Lampung skullcaps, this project intends to encourage and enhancethe creativity of the Makmur Jaya women's farmer group members. This would enable them to becomeentrepreneurs and boost the local economy by selling their handmade skullcaps as souvenirs. Trainingin the creation of skullcaps of various sorts and shapes will be conducted, with the assistance ofartisans from the Adian Tapis Lampung Foundation. Caps with Lampung-themed designs are thefinished product of this training and are ready for sale
