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…
ABSTRACT The problem of waste in Indonesia, especially plastic waste, is still unresolved. One alternative solution for dealing with plastic waste today is to convert the plastic waste into fuel oil. The things studied included the physical and chemical properties of pyrolysis oil. The physical properties studied included viscosity and density, while the chemical properties were the heating va…
ABSTRACT Cadmium (Cd) is a heavy metal that is commonly found in aquatic environments and has a high level of toxicity. Adsorption is the adsorption process of a substance on the surface of another substance due to the molecular attraction that occurs between the adsorbate and the adsorbent. One of the adsorbents that can be used to remove Cd metal is POFA-based zeolite. This study aims to ana…
ABSTRACT In this Era, the waste food give harmful impacts to the environment. This one of the problems of the world community. In fact, many people produce a lot of waste from their leftover food. The cause of this case is the people’s habits in throwing away leftover food. In contrast, there are still many people who are unable to sufficient their food needs. This problem is the background …
ABSTRACT Crime is all kinds of activities carried out by the whole community because it violates the law, social and religion and harms many parties. One of the crimes that often occurs is a crime related to an ATM (Automatic Teller Machine). Perpetrators who enter ATMs usually carry out their actions using head coverings such as helmets, hats, skullcaps and others in committing crimes. To min…
ABSTRACT The substation is one part of the power system that has the potential to experience disturbances such as fault currents and impulse voltages. The grounding system serves to increase the safety of humans and system equipment and also to eliminate or reduce disturbances that occur. This study conducted a design, analysis and simulation comparing the grounding system at a substation that…
ABSTRACT In this day and age, many roads are already using Solar Public Street Lighting (PJUTS). PJUTS is a Solar Power Plant (PLTS) application off-grid for street lighting. Inayah Islamic School plans to build PJUTS on the road in its school complex. The size of the road is small and sourced electrical energy from the sun, it is one of the foundations of research. This study aims to design s…
ABSTRACT Portable coastal radar is an important device for monitoring the security of the borders of Indonesian waters. In the 2019 presidential election debate, President Jokowi said that there were already 11 maritime radar points installed in several parts of Indonesia. This amount is still not enough to cover Indonesian waters as a whole, especially in border areas. Radar consists of sever…
ABSTRACT High population growth in Pekanbaru City has increased the need for housing so that it can directly reduce water catchment areas. For this reason, groundwater conservation is needed as an effort to maintain the existence and sustainability of the condition, nature and function of groundwater in Pekanbaru City. The Pekanbaru City Government emphasized in Pekanbaru City Regional Regulat…
ABSTACK The increase in population in Pekanbaru City causes an increase in the number of movements using vehicles. Traffic flow problems that often occur cause traffic jams, air pollution, sound or noise and accidents.
