Abstract

Rasau Jaya landfill applies an open dumping system. That system results in leachate that potential to cause environmental pollution. One of the efforts that can anticipate this problem is modeling the leachate distribution patterns. This study aimed to model the potential of leachate distribution below the surface both vertically and horizontally. The using method in this study to model leachate distribution patterns is the Wenner configuration geoelectric method. Results showed that the indicated leachate spread 30 m to the northeast and 30-40 m to the southwest. The most in-depth indication of leachate distribution is up to a depth of 20.3 m

Abstract

Soft soil is a type of soil that is difficult to use in construction because it has low bearing capacity and slow settlement due to its fine grain size. In statistics, the relationship or correlation between two data can be predicted using mathematical formulas to find out how much the two data can influence each other. Most of the soil on the surface of the city of Pontianak is dominated by soft soil, so it is important to know how much the coefficient of consolidation and coefficient of permeability can influence each other. From the results of the regression and correlation calculations, the relationship between the permeability coefficient and the consolidation coefficient for the combination of original soil and sand mixed soil is y = 674.7x + 0.0003 with a value of r = 0.4834. The relationship between the permeability coefficient and the original soil consolidation coefficient is y = 321.4x + 0.0003 with a value of r = 0.4173. The relationship between the coefficient of permeability and the coefficient of consolidation of the sand mixed soil is y = 1295.5x + 0.0003 with a value of r = 0.7994. from the experimental results it can be concluded that there is a significant influence between the value of the permeability coefficient and the consolidation coefficient.

Abstract

An-Nur and Darussalam Boarding School use well water for bathing, washing and latrines (MCK). However, well water contains high levels of iron and manganese. Therefore, it's needed clean water treatment technology. The water treatment system consists of aeration, adsorption, and filtration. The purpose of PKM is to provide clean water for partners. The method is a participatory and collaborative method whereby partners participate in planning, socialization and training, and operation and maintenance of water treatment plant. The PKM product is easy-to-use water treatment plant and the processed water is odorless, not turbid and colorless or clear. The main key to the success of clean water treatment PKM in An-Nur and Darussalam Boarding School is good communication and smoothly between PKM team and partners.
