ABSTRACT Coins are used in everyday life in various places such as in banks, supermarkets and automatic weighing machines. So, there was a basic need to automate coin counting and sorting. For these machines it is necessary to recognize coins very quickly and accurately, because further transaction processing depends on this recognition. Banks use money counting machines to count money. It can…
The FEMA P-58-5 method is a method used to evaluate the performance of a building structure using a probability approach. based on the output obtained from PET (Performance Estimation Tools). The purpose of this research is to obtain the performance of the building structure simulated by the influence of the planned earthquake (2017 Earthquake Hazard Map). This research is using the provis…
The need for hot water in everyday life is indispensable for industrial, hospital and household needs, due to the large demand for hot water, one idea emerged, namely a heat pump water heater assisted by solar energy which was designed which mainly consists of an evaporator panel with a surface area of 0.23 m2, a rotary compressor with an input power of 1/6 PK, an insulated water tank which has…
With the fulfillment of electricity needs, the standard of living of the community will increase, uneven population distribution and difficult access are one of the causes of an area not being electrified by PLN. One solution that can be used so that electricity needs are met is to utilize water energy in irrigation canals as an energy source. The obstacles faced in this process are the low…
The presence of peatland in Indonesia has an important role for the sake of environmental perseverance globally. Land fire does not only occur in dry land, but also in wet land. Rokan Hilir Regency is the contributor of forest fire and peatland fire until peatland degradation in Rokan Hilir Regency continues to occur. The problem analyzed in this research was analyzing the hotspot data, the…
The rapid development of carbon-based two-dimensional nanomaterials has attracted the attention of researchers who are working on developing new materials with unique properties, one of which is graphene. As graphene continues to develop, researchers are persistently exploring various synthesis methods to produce high-quality graphene (with minimized layers and defects) in an economical ma…
ABSTRACT Water allocation is a way of distributing water to water users by providing a certain amount of water in a service area (water district) so that it can be distributed fairly, evenly and efficiently. The demand for water cannot be avoided, but it must be predicted and planned for the best possible utilization. The tendency that often occurs is an imbalance between the availability and …

This work was carried out on the campu…
ABSTRACT In the hydrology, information about rainfall on a low time scale (per-hour) is very important. Therefore, rainfall measurements are carried out both on a high time scale (daily) and a low time scale (hourly). In this research, rainfall modeling on a low time scale in Pekanbaru City was carried out using the Neyman-Scott Rectangular Pulse (NSRP) stochastic approach. In the NSRP app…
ABSTRACT The availability of average rainfall data in Indonesia is not sufficient to be used in hydrological analysis. The disaggregation method is one of the data generation methods to obtain rainfall data covering high time scales and low time scales. Rainfall data generated at lower time scales must match data at higher time scales. In this study, rainfall disaggregation of Dumai City w…
ABSTRACT Indonesia is one of the countries with the largest rubber production and palm oil exports in the world. Large production requires large utilization as well. Lack of utilization of a waste can cause accumulation which has the potential to have a negative impact on the environment. This study aims to determine the benefits of crumb rubber as an additive in an asphalt mixture of AC-WC ty…
ABSTRACT Pekanbaru city often experiences flooding, because it has high rainfall and the city's drainage system is not so good, this causes many problems. A city needs a good drainage system. The development of a drainage system in an area aims to provide a system of channels that function to drain water on the surface caused by rain to be immediately drained to the nearest receiving water bod…
Development of road infrastructure, especially local roads in urban areas, is a pillar of economic development in Pekanbaru City because the distribution of goods and services must reach all areas.

The area with the third largest peatland area in Sumatra is Jambi, which is 736,227.20 ha or 14% of Jambi's area. East Tanjung Jabung Regency is an area that has a high potential for land fires to occur, either due to the actions of the community or companies. Peatland fires in this area are closely related to meteorological factors, namely the lack of rainfall as a source of fire extingui…
The load capacity of old reinforced concrete structures is often insufficient to meet current standards. This is due to increased load requirements, inadequate shear requirements of the original design, material degradation, or increased capacity associated with flexural reinforcement. This study experimentally analyzed the behavior of existing reinforced concrete beams 2000 x 150 x 200 mm …
The oil and gas injection well drilling project is one of the methods used to optimize oil and gas production in old oil fields by utilizing water as an injection medium which will later fill the pores of the reservoir rock and force the remaining petroleum to flow into production wells.
