Abstract

Hot Mix Asphalt (HMA) is a Flexible Pavement which has been frequently used as it can be got in with ease. Never the less, the increasing number of passing, vehicles results in premature damage due to overloading. A long term objective of this research is to decrease the premature damage by adding some latex to the pavement mixture of aggregate and asphalt. While its specific objective is to add some latex to HMA pavement mixture to detect the effect of fatigue which can be seen through permanent deformation and rutting.  Having added some latex, it can be detected how serious the damage of the pavement will be. Experimental method was employed by using Bina Marga standardized aggregate, 4,5% - 6% latex addition to petroleum asphalt penetration 60/70 had to go thorugh Beam Apparatus Pavement Test. While Wheel Tracking Machine (WTM) was applied to test, rutting. The analyses of 4,5%- 6% latex addition to Maximum Asphalt Content  result in 2,43 mm and 2,66mm deformation It is suggested to carry  out a research into the effect of 7% and 8%latex addition to Maximum Asphalt Content.

Abstract

The effectiveness of learning management in increasing student motivation, especially through the group discussion method, tends to be passive without proper teacher intervention. This study aims to find and analyze the role of teacher scaffolding in increasing the motivation of student group discussions at SMPN 3 Darangdan. The researcher uses a case study approach. The data collection method uses observation, interview, and documentation study methods of school principals, teachers, and grade IX students. The results of the study show that careful planning in mapping students' Zones of Proximal Development (ZPD) as well as the provision of dynamic support (such as hints and encouragement) are significantly able to arouse students' intrinsic motivation and independence. The process of fading or gradually reducing assistance has proven crucial in changing the dynamics of the discussion from passive to active and collaborative. This study concludes that the mastery of scaffolding techniques by teachers is an effective classroom managerial strategy to realize the quality of student-centered learning and in line with the vision of RAMAH at SMPN 3 Darangdan.
