Abstract

Multi Soil Layering (MSL) is a procedure for treating liquid waste that employs soil as its primary medium. In addition to soil as the primary medium, it can also use sedimentation waste (PDAM) as an alternative. This study included two variations: HLR value variations and HRT value variations. The results indicated that the HLR values were 11.48 L/m2/hour, 4.76 L/m2/hour, and 2.48 L/m2/hour, with 2.48 L/m2/hour exhibiting the highest level of effectiveness. The pH and DO values changed to 7.4 and 19.5 mg/L, respectively, and the TSS value effectiveness reached 76.32%, the TDS value degradation reached 75.21%, the turbidity degradation reached 99.69%, and the COD degradation reached 99.66. At the HRT values of 4 hours, 6 hours, 8 hours, 10 hours, and 12 hours, the effectiveness level of the greatest HRT variation occurred at 12 hours, where the value of changes in pH and DO became 19.5 mg/L and became 7.5, and the effectiveness COD value degradation reached 98.95%, BOD value degradation reached 51.11%, and TSS degradation reached 73.5%. The obtained results indicate that the MSL method with PDAM sedimentation waste material is capable of reducing pollutant levels in the tofu manufacturing industry.

Abstract

This research is motivated by the fact that many students are not yet ready to continue their education to college. Students' unpreparedness can be seen from the low desire of students to continue their education to college. This study aims to describe students' readiness to continue their education to college based on aspects: 1) achievement, 2) behavior, 3) motivation, 4) social engangement, 5) family circumstances, 6) school characteristics. The research method used is a quantitative method with a descriptive approach. The population this study was grade XII students of SMA N 1 Koto Balingka Pasaman Barat, with a research sample of 189 students selected using a purposive sampling technique. Data were obtained using the student readiness instrument to continue their education to college. Data were processed using descriptive statistical techniques. The results of the study showed that the readiness of students to continue their education to college: 1) overall is in the high category of 63%, 2) achievement is in the high category of 46%, 3 behavior is in the high category of 51%, 4) motivation is in the high category of 44%, 5 social engangement is in the low category of 30%, 6) family circumstances is in the high category of 46%, 7) school characteristics is in the high category of 41%. This means that most students already have good readiness to continue their education to college. It is hoped that students can prepare themselves to continue their education to college and utilize the BK services at school optimally.
