Peatwater is water with a pH value ranging from 3-4, reddish-brown in color, containing high levels of organic matter, iron, and manganese, making it unsuitable for household use. One alternative to improve the quality of peat water is through the use of a multimedia biosand filter, which involves filtration using more than two types of media, such as pumice stone, quartz sand, and zeolite arra…
Peat water is a type that falls short of health standards, characterized by a reddish-brown color, high organic content, and low pH. It is prevalent in Riau Province, making it a vital water source for the community. An alternative for treating peat water is the biosand filter. This research aims to analyze the influence of varying media thickness, including gravel, pumice, quartz sand, and act…
Project management is the application of the best knowledge, expertise, skills, technical methods with limited resources, to achieve predetermined goals and objectives in order to obtain optimal results in terms of cost performance, quality, and time, as well as work safety. Project scheduling is a form of project planning that is made with the aim that the project is completed on time. Critica…
This research evaluates the performance of drainage channels along Jalan Suka Karya, Tuah Karya Village using physical and non-physical indicators from Module 19 Drainage System Performance. Physical indicators include condition, infrastructure and channel maintenance, while non-physical indicators involve regulations, institutions, operational management, maintenance and community participatio…
Writing this final assignment about planning and calculating budget plans (RAB) aims to plan buildings and calculate cost budget plans for constructing a building. Data collection was carried out by conducting a literature study of manuals and documents related to building planning. Apart from that, data collection was also carried out directly in the field to collect data on land conditions, l…
Kualanamu International Airport is located in Deli Serdang Regency, North Sumatra Province. The development of air transport movements at this airport indicates that the passenger terminal facilities which have an existing area of 118,930 m2 with a capacity of 8.9 million passengers per year are no longer able to accommodate the existing passenger volume. This can be seen from the increase in t…
Traffic congestion is a common issue in urban road traffic, and the resulting traffic jams adversely affect road users. Congestion occurs when traffic approaches the road capacity. HR Soebrantas Road is a collector road connecting the city of Pekanbaru and Kampar Regency. This road has four lanes, two in each direction (4/2)D, and holds the status of a provincial road. Each segment of the road …
In Indonesia, industrial waste such as elastic rubber powder from used vehicle tires and fly ash from power plant waste can be used in construction. Fly ash is a geopolymer substance or alternative adhesive that can be used in place of cement in mortar mixtures. The purpose of this study was to examine the effect of silicate modulus (Ms) variation on the resistance of hybrid fly ash geopolymer …
Concrete is a material that has high strength to withstand loads. One of the uses of concrete in the construction field is as a road pavement which is often called rigid pavement. Rigid pavement is brittle so it cannot withstand large tensile loads, so it requires rubber crumb as an added material. Waste rubber crumb from used tires has good benefits for concrete to increase the strength of con…
Eggshell is a type of solid waste that is mostly produced from the food industry. Eggshell ash produced through the combustion process at 900oC will produce a CaO content of 44.4% so that it has the potential to be a substitute for lime in making cement. This study aims to assess the maximum compressive strength, UPV, tensile strength and shrinkage of concrete with cement substitution using egg…
Eggshells are a waste that is generated in large quantities. In fact, eggshells have potential as a sustainable material in construction because they contain calcium carbonate which can increase the strength of concrete and reduce the use of cement. However, eggshells also have disadvantages, especially in terms of impermeability to water and aggressive substances. These weaknesses can be compe…
The utilization of waste rubber and waste fly ash as basic materials in the manufacture of materials is an effort made to mitigate negative impacts on the environment. Rubber powder waste that is elastic and resistant to high temperatures is derived from old vehicle tire waste. Fly ash from PLTU waste is one of the geopolymer materials or alternative adhesive to replace cement. Both wastes can …
River water resources are developed as an effort to support human life by providing and utilizing water. In practice, planning the development of water resources in a watershed (DAS) requires field discharge data as the main data. However, discharge measurement data in the field is generally limited and the most common data is rainfall data. Therefore it is necessary to transform rainfall data…
The Waduk Buatan built by the government in the 80s is a reservoir for the Ambang and Merbau watersheds located in Lembah Sari Village, Rumbai Pesisir District, Pekanbaru City, which was initially used as a source of irrigation water for the surrounding area's rice fields, which was later converted into a PDAM raw water source. The basic contour of The Waduk Buatan is needed to determine the ma…
The development of construction needs to pay attention to the condition of the subgrade so that it can carry the load above it. Peat soil is known to have high moisture content, organic content and pore number. Therefore, it needs to be stabilized before being used as a subgrade. Microbial-induced calcium carbonate (CaCO3) precipitation is an environmentally friendly soil improvement that can …
Mandau District is the largest economic and market center in Bengkalis Regency. Buying and selling activities in the Mandau Market area cause crowds of people shopping, thus affecting the level of service for pedestrian facilities. This research aims to determine the characteristics and level of service of pedestrian facilities in the Mandau Market area. This level of service refers to Minister…
Peat soil has low strength, high compressibility, and high moisture content. Therefore, peat soil must be stabilized so that it can be used as a base for construction. MICP is an environmentally friendly soil stabilization method using bacteria. The bacteria will produce calcium carbonate that will fill the space between the peat soil voids. The use of sand as an additive is considered to impro…
