ABSTRACT This study examines the durability of PCC concrete and POFA concrete with the addition of silica fume soaked in peat water. POFA is used as a cement substitute with variations of 0%, 20% and 40% and the addition of silica fume is 10%. The design compressive strength is 20 MPa. Observing the specimens was carried out in normal water for 28 days and then immersed in peat water for 0…
ABSTRACT The Rokan Watershed (DAS) is a watershed located in the Rokan Hulu Regency. The Rokan Watershed has an area of 1036 km2. The problem of water resources occurs during the dry season this watershed experiences drought, while in the rainy season the water discharge will increase and cause flooding. Calculation of the need for irrigation water requires an evapotranspiration value (ET0…
ABSTRACT Asphalt is one of the materials used in road construction, this material was chosen because it can produce flexible, safe and comfortable pavement. One of the functions of adding fillers is to minimize the use of asphalt base materials, where this filler has a significant effect because it functions as a cavity filler. The filler used is factory waste, namely fly ash and bottom as…

Landslide is one of the disasters that has a high level of damage. This research aims to identify slope stability which was modeled by using a based finite element method software, i.e. Plaxis V.8.2. The data that were used are slope dimension, material properties, and reinforcement properties. These data were used as input in modeling. The slope was modeled in the condition before the reinforc…
ABSTRACT Wood is a natural construction material that is very commonly used in the world. Wood is still needed as a building material because of the advantages possessed by wood. However, the availability of wood today is increasingly limited and the price is increasingly expensive. To overcome this, palm oil trunks can be used as an alternative construction material that can be used as a …
