Abstract

The SDGs or Sustainable Development Goals are the 2030 Global Development Agenda which has become a commitment from all countries in the world, including Indonesia. Goal 6 Clean water and sanitation aims to ensure the need for clean water is adequate for all levels of society. Achieving these goals is highly dependent on community participation to help accelerate the SDG's program in the clean water and sanitation sector. The need for clean water can be met by utilizing the existing clean water supply while taking into account the impact on the environment. Rainwater has the potential to become a clean water resource by utilizing a simple rainwater harvesting system consisting of gutters, piping systems, and water tanks. By utilizing rainwater resources, it can help reduce the use of groundwater due to overexploitation of groundwater. Service activities are carried out online and offline together with partners SMPN 06 Pekanbaru by build Rain Water Harvesting (RWH) construction; so that later the RWH building can become a pilot activity/ best practice for other schools and the surrounding community.

Abstract

Tanjung pinang City is located in Riau Islands Province, has coral and kelanauan or kelempungan soil types, but in its implementation there is one location point along 50 meters where the subgrade does not reach the minimum standard density. The purpose of the study was to determine the value of soil density in the form of maximum dry weight and free compressive strength values obtained after a mixture variation of sand, cement and DIFA Soil Stabilizer. The research was conducted using experimental method of laboratory testing. Soil stabilization by mixing native soil plus sand, cement and DIFA soil stabilizer. The compositions carried out were native soil plus sand at 0%, 10%, 20% of the dry weight of the soil, cement 8% of the dry weight of soil and sand weight, and DIFA soil stabilizer 2% of the weight of cement. The testing methods were standard proctor and UCS tests to obtain the density value and free compressive strength value of the stabilized soil. The soil density value based on the standard proctor test is the dry weight value of native soil of 1,410 kg/m3, soil mixture plus 0% sand and 8% cement of 1,450 kg/m3, mixture of 10% sand and 8% cement of 1,470 kg/m3, and mixture of 20% sand and 8% cement of 1,490 kg/m3. The UCS test result of the original soil was 291.50 kN/m2. The test result of mixed soil with 0% sand, 8% cement and 2% DIFA soil stabilizer was 991.25 kN/m2. The test result of mixed soil with 10% sand, 8% cement and 2% DIFA soil stabilizer was 1,241.59 kN/m2. The test result of mixed soil with 20% sand, 8% cement and 2% DIFA soil stabilizer was 1,743.63 kN/m2.
