Abstract

Self-Compacting Concrete (SCC) is a type of concrete capable of compacting itself without the use of vibrators, characterized by a high slump and the ability to flow under its own weight to fill formwork completely without segregation, thereby simplifying the construction process. The materials used to produce SCC include fine aggregates, coarse aggregates, water, and cement, combined with admixtures in the form of superplasticizers. The superplasticizers added in this study were Consol SG at 0.3% and Consol N11 LN at variations of 0.6%, 1.4%, and 2%. Workability test results for SCC indicated slump flow values of 39.17 cm for 0.6% SCC, 56.72 cm for 1.4% SCC, and 61.24 cm for 2% SCC. L-Shape Box tests yielded results of 0.067 for 0.6% SCC, 0.949 for 1.4% SCC, and 0.987 for 2% SCC. The V-Funnel Test produced times of 32 seconds for 0.6% SCC, 11 seconds for 1.4% SCC, and 8 seconds for 2% SCC. Compressive strength testing of normal concrete showed values of 22.36 MPa at 7 days, 28.79 MPa at 14 days, and 35.28 MPa at 28 days. For SCC with 0.6% admixture, compressive strengths were 23.85 MPa at 7 days, 29.58 MPa at 14 days, and 36.17 MPa at 28 days. SCC with 1.4% admixture yielded compressive strengths of 25.27 MPa at 7 days, 30.16 MPa at 14 days, and 38.26 MPa at 28 days. SCC with 2% admixture reached compressive strengths of 28.04 MPa at 7 days, 33.62 MPa at 14 days, and 38.63 MPa at 28 days. Water absorption tests at 28 days showed values of 120 g for normal concrete, 110 g for SCC with 0.6% admixture, 100 g for SCC with 1.4% admixture, and 110 g for SCC with 2% admixture.

Abstract

Environmental safety and order are important aspects of creating a harmonious and prosperous community life. Environmental Security Posts (Pos Kamling) play an important role as a community-based security system in maintaining order and preventing crime. However, residents in RT. 17, Sukamulya Village, Sematang Borang District, Palembang City are facing the problem of the increasing number of vehicle theft cases parked in their home yards. Therefore, this community service activity is carried out with the aim of designing and building a neighborhood watch post as a solution to improve environmental security. The methods used include field surveys, direct observation, and interviews with RT officials and local residents to collect relevant data and information. The results of this service include the preparation of Pos Kamling planning documents, including the calculation of the Budget Plan (RAB), as well as the physical construction of the post until it is ready for use. Beside being a security monitoring center, the neighborhood watch post also serves as a means of social interaction that can strengthen relationships between residents. A Pos Kamling management unit was established after the activity to carry out the patrol SOP, supply the duty schedule, oversee the fast reporting channel, and accept the transfer of DED, RAB, and SOP papers as operational instructions.
