Damage to the pavement layer due to vehicles with Over Dimention Over Load (ODOL) causes swelling costs due to maintenance of damage roads before the planned life limit. Filler are able to improve the quality of pavement. Research by replacing filler material was carried out to find materials that can improve pavement stability, in this case the material used is red brick production waste owned by UD. Bata Pres MRH, Mojokerto. Based on the sieve analysis test, the red brick waste filler material that passed sieve No.200 was 84,77% and the specific gravity test obtained a value of 2,746. Based on the results of marshall testing on the AC-BC mixture using the requirements of Spesifikasi Umum Bina Marga (Revisi 2) of 2018 for flow with asphalt content of 4,6%, 5,1%, 5,6%, 6,1% and 6,6% respectively has results of 3,40 mm, 3,47 mm, 3,57 mm, 3,73 mm and 3,77 mm and for stability values sequentially has a value of 1164,3 kg, 1180,0 kg, 1287,2 kg, 1177,1 kg and 1167,2 kg. based on the test results, it has fulfill the requirements of the Spesifikasi Umum Bina Marga (Revisi 2) of 2018 for AC-BC mixtures.

The initial thing to do is to hold discussions and assist in supervising the implementation of road paving activities with the aim that the implementation of road paving activities can be carried out in accordance with the plans and implementation methods that meet the implementation standards and technical standards of road pavement. Taking into account the current conditions in order to support smoothness to increase productivity, driving comfort, travel, and the beauty of the village, it is necessary to have infrastructure in the form of good roads as well as the challenges of building and repairing environmental roads.

In repairing the asphalt overlay (overlay) of the road pavement surface, it is necessary to pay attention to the tools, materials and implementation methods that are suitable for the asphalt location. Good development can be realized because of the cooperation of all parties involved, the supervisory team who provide input for controlling this development project. All the obstacles that were initially felt to have a solution when the existing cooperation strengthens each other.

The objective of analyzing the effectiveness of the physical model for treating greywater and rainwater using multilevel filters is to turn it into clean water as an alternative to raw water in handling the water crisis. as well as the addition of PAC (Poly Aluminum Chloride) and soda ash (Sodium Chloride) to neutralize the pH.

This simple tool is able to increase the pH and turbidity of household wastewater. The background to the creation of this tool is the increasing amount of waste water, while in certain areas there is a shortage of water. This simple tool is made of a stainless pipe with a diameter of 3” and a length of 20 cm while the lower part is a filter which will be filled with certain materials, namely: multilevel sand filters. Based on the research results, the tool can filter waste water. The processing method used is filtration using sand filters and chemical drugs and a combination of sand filtration processes to produce clean water.

The multilevel filtration method is able to remove pollutants contained in greywater wastewater and can be a solution for fulfilling clean water according to the 2001 Permenkes.
