Abstract

Infiltration wells are one of the effective infrastructure in draining rainwater so that they can reduce waterlogging, but existing infiltration wells need to be reviewed for their effectiveness as water shortages are still occurring especially in the Purwantoro Village.The study aims to determine the effectiveness of Infiltration wells and calculate the appropriate number of infiltration wells in Purwantoro Village. The method used in this research is a hydrological analysis, planned flood discharge analysis dan infiltration well effectiveness analysis. The results of the study showed that the effectiveness of existing infiltration wells in Purwantoro Village varies greatly, with the highest at 82.8% and the lowest at 11.3%. To increase the effectiveness of infiltration wells, as many as 109 infiltration wells are needed in Purwantoro Village to reduce waterlogging. The conclusion of this study is the lack of effectiveness of infiltration wells in Purwantoro Village because the number of infiltration wells is still limited, so it is necessary to add infiltration wells and maintenance of infiltration wells is needed to reduce deposits contained in infiltration wells.

Abstract

The aim of this research is to determine the impact of applying an ethnopedagogical approach through project based learning (PjBL) on students' self-regulated learning (SRL). This research uses the quasi experimental method and pretest-posttest non-equivalent control group design. As many as 100 of 353 students class X at SMAN 3 Banda Aceh were selected through purposive sampling technique. A non-test instrument was used to measure students' SRL. Data were analyzed using descriptive statistics and an independent sample t test. The result of the hypothesis test illustrates the sig. > 0.05 (0.566 > 0.05), then H0 accepted. The result of descriptive analysis shows that the increase of the average score in the experimental group was greater than the control group after the intervention. Thus, applying an ethnopedagogical approach through PjBL provides a positive impact on increasing the students’ SRL but there is no significant influence.
