ABSTRACT Street Durian is an undivided 2-lane 2-way collector road (2/2 UD) located in the Pekanbaru area. This road is traversed by many types of vehicles, both light vehicles, medium vehicles, so that during rush hours traffic jams or delays are common. The method for calculating this unsignalized intersection is guided by MKJI 1997. Based on the research results it can be seen that the peak…
ABSTRACT Merbau wood is a type of wood that is easily recognized for its fiber texture and is widely used for paneling, flooring, windows and doors. This wood has very low shrinkage, so it is not easily deformed when dried. In this study, the wood waste used was sawdust of merbau wood which was used as a partial replacement for sand in the manufacture of mortar with the aim of knowing the effe…
ABSTRACT To improve the performance of the fixed wing flying vehicle, in 2021 the Mechanical Engineering Flying Robot Team of the University of Riau again redesigned the SSU-01 fixed wing type of VTOL flying vehicle. The design process for the SSU-01 VTOL fixed wing flying vehicle has been completed at the design stage. The second stage of the design of the fixed wing VTOL vehicle is the manuf…
ABSTRACT The problem of delays in handling waste problems can cause big problems in a developing city. This problem is caused by several things, especially in terms of waste management which is getting worse and worse in a city which can result in a serious disaster for that city. Therefore, the authors conducted a research on internet-based automatic trash cans using ultrasonic sensors as a …

ABSTRACT Cellulose (C6H10O5)n is one of the long-chain polymers of polysaccharides prepared from saw-monomer β -glucose. Cellulose is the principal carbohydrate synthesized by plants dan occupies almost 60% of the components of plant structure. The purpose of this study is to extract cellulose from the pineapple wastes semi-mechanical and obtain cellulose powder by the methods of delignificat…
ABSTRAK The window control system is useful for opening and closing automatically and manually using Arduino as the control center. The use of this project makes it easy to close and open windows when it is dusk and it is raining. Its utilization is very useful if it is used on windows of multi-storey buildings such as hotels, schools, factories and can also be used for household windows. This…
ABSTRACT The Internet of things (IOT) based laser alarm system is useful for helping people protect an environment or place, by utilizing the workings of a light sensor. This light sensor will be irradiated with light from a laser that is reflected in places that are considered dangerous. The laser light received by the LDR will change its value if something is blocking it. This change will…
ABSTRACT The disposal of cigarette smoke in a closed room works when cigarette smoke is detected by the MQ 2 sensor, processes data to the Arduino Uno and gives a signal to the relay and turns on the dc fan automatically. When the MQ 2 sensor detects smoke and the ppm value is above 40 ppm which is displayed on the 16 x 2 LCD, the fan automatically activates to remove the smoke in the clos…
ABSTRACT Automatic clothesline is useful for protecting clothes that occur when the weather changes suddenly using an automatic control system using Arduino Uno as its control. The use of this project provides convenience in terms of drying clothes that can help relieve and reduce when leaving clothes drying. This tool is equipped with Ardiuno Uno as a control center to receive signals fro…
ABSTRACK One of the weaknesses of the concrete material is that it is easily damaged in aggressive or extreme environments, concluding in seawater. Wet dry cycle mechanism can be used as a simulation of concrete exposed to be attacked by sea water. Shellfish waste that goes through a burning process at 700°C will produce a CaO content of 55.10%, so it has the potential to be a substitute for …
ABSTRACT Initial damage to the structure occurs in the outer layers of the affected surface exposure to the peat environment and the static and dynamic movement of the structure. To prevent structural damage, the latest technological innovations are needed in the use of mortar constituent materials to increase the strength of the mortar. Polymer mortar is a composite material formed from a mix…
ABSTRACT Beams are a rigid part of the structure of a building. This beamis specifically designed to be able to withstand and transfer loads to column. Beams without shear reinforcement will experience changes in behavior both in terms of strength and failure patterns. The purposes of this study were to analyze the behavior of reinforced concrete beams reinforced with the Deep Embedment me…
ABSTRACT Development project activity is an activity whose start and finish schedule has been determined, with the allocation of certain resources and intended to produce a product. If there is a delay in the schedule, it will affect the objectives of the project. There was a delay in the Makorem Main Building Development Project between the planned schedule and the actual implementation. The …
ABSTRACT This research aims to develop the durability of acrylic polymer concrete. In this study, the durability of concrete investigated is concrete strength, concrete impermeability and corrosion of concrete reinforcement. The strength of concrete is shown by testing the compressive strength of concrete and the tensile strength of concrete. The experimental results showed an increase in conc…
ABSTRACT Petroleum production shows a downward trend. Biodiesel is a renewable energy source that can be an alternative fuel similar to conventional (fossil) diesel oil. The use of biodiesel in diesel engines is still experiencing problems and results in the performance of diesel engines not being optimal. Several ways that can be use to improve engine performance in the use of biodiesel inclu…
ABSTRACT Currently, the supply of fossil energy such as oil in Indonesia, which has been used so far, is running low. Therefore, efforts are needed to find renewable energy. One alternative fuel that is environmentally friendly and comes from renewable resources is biodiesel. The biodiesel used is generally mixed with diesel, which is called biodiesel, each biodiesel-solar mixture will have it…
ABSTRACT Fulfilling the need for electrical energy that is not optimal, especially in rural areas, makes it difficult for people to be able to carry out activities like other communities, such as in other areas where electricity has entered the area. The Portable Screw Turbine is a small-scale power plant, where this turbine works by utilizing low head water flow and high water discharge to pr…
ABSTRACT The increasing amount of plastic waste is causing problems for the environment, due to the non-degradable nature of plastic in the soil. One of the plastics that are widely used in everyday life is polyethylene terphthalate (PET). It takes decades in the soil to decompose the wastes from these plastic materials. Another alternative for handling plastic waste is the recycling process w…
