A business that has the potential to advance the economy is a business in the culinary field, where businesses in the culinary field are businesses that are often …
ABSTRACT Taman Karya Pekanbaru city’s road is a local secunder road connecting between the activity centers of Pekanbaru City . Where it has a road length of ± 1.5 kilometers, a lane width of 6 meters. The purpose of this study is to determine the types of damage and find out the index value of the bending pavement condition on Taman Karya Pekanbaru city’s road using the Pavement Conditio…
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…
