Abstract

Concrete in its use as a construction material continues to increase and is increasingly widespread. The high level of use of concrete is caused by the many advantages offered by the use of concrete. Additives in concrete are one of the materials in concrete that can be innovated to obtain concrete characteristics and specifications. Additive material used in this research is rice husk ash. Rice husk ash used as an additive in this study was rice husk ash waste from Kerinci Regency. This research was conducted.with the aim of knowing how the use of rice husk ash as an additive can affect the compressive strength of concrete. The concrete used is cylindrical concrete with a concrete design quality of fc' 20 MPa. This research was conducted by experimental method. The results of the study with variations in the addition of rice husk ash to concrete as much as 0%, 6%, 8%, 10%, and 12% to the weight of cement obtained an optimum compressive strength value of 29.32 MPa. Laboratory tests on the compressive strength of concrete proved that the compressive strength.of concrete increased linearly with the addition of 6%, 8% and 10% rice husk ash.

Abstract

Particulate emissions from boiler activities are known has a negative impact on health, such as causing respiratory problems. The particulate emission dispersion model generated from the chimney of a boiler can be known using the aermod modeling tool, through this model, the concentration of particulate emissions received by the environment around the activity can be studied. The design of the boiler chimney is also known to affect the concentration of particulate matter that is dispersed. This study aims to determine the effect of chimney design on the distribution of particulate emissions from boilers activities. The particulate dispersion model was carried out using the aermod modeling tool with several fixed variables, namely climatic conditions, the location of chimney and reseptor, and particulate emissions coming out from boiler, while the independent variables were variations in chimney diameter and heights. The results of particulate distribution model show that chimneys with a diameter of 2 meters and a height of 28 meters have a wider distribution of 93.96 meters from the emission source with a maximum concentration of 29.41 µm/Nm3. While the lowest concentration received by the receptor of 2.51 µm/Nm3 came from the chimney with a larger diameter and higher chimney.
