Rainfall is an important element in the hydrological cycle. Rainfall is measured in inches or millimeters, which shows the height of rainwater that falls and covers the surface in a certain period. For example, 1 millimeter of rainfall means that the height of the rainwater that falls reaches 1 millimeter and covers the ground surface with that thickness. In this research, rainfall data was eva…
Road damage is a condition where the quality of the road pavement decreases so that it can disrupt the comfort and safety of road users. On the Merpati Sakti road there is a lot of damage which can pose a risk of accidents. The aim of this research is to determine the types of damage and determine the index value of the flexible pavement condition on Merpati Sakti road. This research method use…
ABSTRACT An earthquake can be defined as a vibration or shock by the release of energy that causes seismic waves. In addition, earthquakes can also occur due to the shifting of the earth's plates. The limited land available and the increasing demand for space have caused high-rise buildings to be built close to each other. However, during an earthquake, these buildings can sway in different pa…
Groundwater is water that occupies a cavity in a geological layer that is continuously replenished by nature. According to David K. Todd's theory, it is known that the groundwater table tends to follow the elevation of the land above it. This theory was proven by several previous researchers in flat areas and obtained appropriate results. This study aims to compare the measurement results of th…
Light brick is an alternative building material for building walls that has a smooth and lighter surface. The effect of high temperatures due to fire can result in a decrease in the characteristics of lightweight bricks. Innovations continue to be made to strengthen the characteristics of lightweight bricks, one of which is the addition of polypropylene fiber which has good mechanical and therm…
The structural design method that assumes the column base as fixed or rigid is still frequently used due to its simplicity and conservative nature. This approach is popular because it does not require calculations of the actual soil stiffness, thereby easing implementation. However, this method results in larger internal forces within the structure, which means relatively higher seismic loads. …
The clarity and accuracy of rainfall analysis in a region greatly depend on the distribution and the ideal number of rain gauge stations. This research examines the density of existing rain gauge stations based on the World Meteorological Organization (WMO) standards and rationalizes the number and distribution patterns of rain gauge stations using the Kagan-Rodda method. This method analyzes v…
Concrete is obtained by mixing Portland cement, fine aggregate, coarse aggregate, and water with or without the use of additives. To get concrete with better strength, additional materials are used. One of the additional ingredients used is Bestmittel. This research aims to determine how much influence the addition of Bestmittel has on the compressive strength of concrete, without reducing the …
One of the additives in concrete is Bestmittel which includes type E (water reducing and accelerating admixture) additives that function to accelerate hardening, reduce water consumption and improve workability. The purpose of this study is to determine the effect of Bestmittel on the compressive strength of concrete and to determine the percentage increase in normal concrete compressive streng…
Urban flooding is triggered by changes in land use from open areas to residential areas. Therefore, this research aims to determine the existing condition of drainage channels and solutions to overcome problems in drainage channels in Tampan District, especially on Jalan Teladan, where water often occurs when it rains, because there is a lot of accumulation of rubbish, sedimentation, and damage…
The road opening and closing system aims to enable construction work to b carried out safely, but the system has an impact on traffic and mobility of road users, causing congestion. This congestion causes delays and queues of vehicles. So road users spend more to buy foel and spend more time traveling. The aim of this research is to analyze the characteristics of queues and predict the v…
The Sanglar River is one of the rivers located in the village of Reteh Subdistrict, Indragiri Hilir Regency, Riau Province, Indonesia. Reteh Subdistrict in Indragiri Hilir Regency ranked first in the occurrence of disasters in Riau Province during the year 2021. Therefore, the researcher chose the Sanglar River as the research object, with a river length of approximately ±2.5 km. Due t…
PDAM Tirta Siak faces various issues that affect the level of trust and satisfaction among the public regarding its clean water services. Despite the addition of new customers and reconnections, quality and continuity of service remain significant challenges, with numerous complaints related to water pressure, inaccurate meter readings, and unprofessional attitudes of staff. Additionall…
Traffic accidents are a serious problem that always occur from time to time on the road. Traffic accidents occur from a combination of several factors consisting of human factors, vehicle factors, road factors and environmental factors. The research was conducted on roads in Pekanbaru City which had a high accident rate from 2017-2023. Data from the Riau Police Traffic Directorate durin…
The conversion of land that occurred in the upstream part of the weir into fish ponds and oil palm plantations as well as the irrigation network not being maintained resulted in a lot of damage to buildings and irrigation channels in the Paku River irrigation network which resulted in the water discharge being small, as a result, rice fields in the downstream areas experienced water sho…
Indonesia is a country that has a high earthquake potential because it is located in the Pacific Ring of Fire. The buildings that function for the public interest must be designed in such a way as to avoid collapse, so as to minimize the number of casualties. Therefore, this research takes a 6-story building with dilation that functions as an educational building. Educational buildings must…
In waterworks planning efforts, the hydrological component is very important. The main component in hydrology is rainfall data, rain stations that are tasked with recording rainfall data. To obtain quality hydrological data, it is necessary to evaluate the number of rain posts that are evenly distributed to represent the hydrological conditions of the area of influence. This study was c…
Indonesia is located in the meeting zone of three tectonic plates, namely the IndoAustralian plate, Eurasia, and the Pacific plate, besides that Indonesia is also located in the ring of fire, causing Indonesia to experience frequent earthquakes. Earthquakes can cause both material and non-material losses, one of which is damage to building structures. Analysis of earthquake-resistant str…
