Abstract

Roads are transportation infrastructure whose needs in Indonesia continue to increase, along with the increasing number of vehicles. Road construction is a construction that receives traffic loads, therefore it is expected that a road pavement layer must have a strong pavement construction and be able to receive loads from traffic users. AC-WC (Black-top Concrete - Wearing Course) asphalt layer is a road pavement construction consisting of asphalt composition, coarse aggregate, fine aggregate and filler. Fillers in asphalt mixtures function to increase the binding power of AC-WC asphalt, so as to improve mixture stability and fillers can fill the voids between aggregate particles, filler commonly used is stone ash. This research will be conducted with the addition of broiler eggshell filler and porland cement in the Asphalt Concrete wearing Course (AC-WC) mixture. The research was conducted with an experimental method conducted in the Civil Engineering laboratory of Abdurrab University. The specification used in this study is Public Road Revision 2 Year 2018, The optimum asphalt content (KAO) used was 6.5%. Based on the results of the study, the largest marshall stability and melting value is found in the 100% cement filler variation, which is 1772.7 Kg and the value of flow value (melting) 3.77 mm while the largest marshall quotient (MQ) value is found in the 25% eggshell filler variation, 75% cement, which is 529.2 Kg/mm.

Abstract

This research aims to determine differences in soil acidity, C-microorganisms and the growth of spring onion (Allium fistulosum L.) on peatlands based on the difference in distance from waterways. The study will be conducted from February 2022 to May 2022. The implementation of the research is located in the Greenhouse and in the Laboratory of Physical Chemistry and Biology, Department of Soil Science, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. This research method is quantitative research with a survey approach using exploratory descriptive methods. The data analysis used was by paired T-Test analysis to find out the differences in parameters observed over a period of five days. The result of this study was that there was a difference in soil acidity and growth of spring onion plants, while C-microorganisms was not.
