Abstract

In order to ascertain the community's readiness to adopt organic waste management specifically, household waste through the composter and biopore programs. This study will analyze household waste management in the Komplek BTN Bukit Teukuh by using community preference analysis. It will do this by utilizing ordinal data from the SPPS application, which has a Multidimensional Scaling Analysis (MDS) feature. With 298 residents and 51 Heads of Families (KK), the study's focus is a housing area in the BTN Bukit Teukuh Complex, Kota Juang District, Bireuen Regency. Storage, collection, transfer, transportation, processing, and final disposal are just a few of the buildings and infrastructure that will be used in waste management activities. Composter and biopore technology are two technologies that can be used to overcome problems in organic waste processing through communal-based composter technology. Based on field observations that have been carried out, data was obtained that organic waste produced in the BTN Bukit Teukuh Complex with a total of 51 families (KK) is 0.3 to 0.45 kg/day in each house, so the total organic waste obtained is 22.95 kg/day. The results of the study in the form of MDS analysis showed that 89% of the community's preferences had implemented the container aspect, 77% the transportation aspect, 55% of the community participated in communal-based waste management, 45% the container aspect, and 10% the composter aspect.

Abstract

The performance of Asphalt Concrete–Wearing Course (AC-WC) mixtures is strongly influenced by filler characteristics that control mechanical resistance and volumetric stability. Although nano zeolite has demonstrated potential for improving asphalt mixture performance, previous studies mainly focus on binder modification or advanced performance-based tests, limiting their applicability in routine mix design practice. Consequently, the role of nano zeolite as a filler substitute in conventional hot mix AC-WC mixtures evaluated using fundamental Marshall parameters remains insufficiently explored, and the optimum substitution level for practical pavement applications has not been clearly established. This study aims to evaluate the effect of nano zeolite filler substitution on the Marshall and volumetric characteristics of AC-WC mixtures and to determine the optimum substitution level based on standard mix design criteria. The Optimum Asphalt Content (OAC) was determined at 6.04% and applied as a constant asphalt content. Nano zeolite was used as a partial replacement of cement filler at substitution levels of 0%, 25%, 50%, 75%, and 100%. Evaluated parameters included Marshall stability, flow, Marshall Quotient (MQ), density, VIM, VMA, and VFA. The results indicate that a 50% nano zeolite substitution yields the optimum performance, producing the highest Marshall stability and MQ while satisfying specification limits. These findings provide practical guidance for applying nano zeolite as an alternative filler in AC-WC mixtures using conventional Marshall based mix design.
