Abstract As the demands for electrical energy sources in Indonesia increases, the Indonesian government calls for developing electrical energy sources through the provision of renewable alternative energy power plants which have enormous potential, to be developed in Indonesia. Among them are solar power plants, which are realized using solar cells. An alternative power plant in the form of a …
ABSTRAK The fuels which is often used in steam power plant come from limited fpssil fuels. The limited fossil fuels forces us to fins another alternative fuels. One of alternative fuels which is used in steam power plant is biomass. Coconut coir is biomass which has potential to become alternative fuels. Availability of coconut coir in Pulau Burung is over supply. This paper aims to calculate …
ABSTRACT Solar panels have low efficiency because they cannot fully convert solar energy into electrical energy, coupled with the surrounding environmental conditions with erratic weather which also affects the output of solar panels to be unregulated or constant. The purpose of this research is to produce a design tool for a regulated dc buck boost converter power supply 24 V ± 5% of solar c…
ABSTRACT Tourism in Indonesia continues to grow in various regions. Riau Province is one of the provinces in Indonesia that continues to develop the tourism sector. The diversity of customs, culture and natural beauty can attract tourists to visit. Bengkalis Regency is one of the regencies in Riau which has various natural tourist destinations. With an area of 8,426 km², there is a lot of…
Abstract Screen printing is a moulding process technique that uses a screen with a certain density and is generally produced by nylon or silk (silk screen). Screen printing uses the basic ingredients of textile paint which can be published in any desired media. The purpose of this project is to modify the resulting machine easier to move with a smaller size of the cup screen printing. In the m…

ABSTRACT Transfer devices for paralyzed and elderly patients are tools that we often encounter in the world of health, such as: wheelchairs, stretchers, gurneys, and others. The process of lifting and moving patients and the elderly carries risks for staff. Because there are some difficulties in moving patients from one place to another. If this work is carried out with the position of the dist…

ABSTRACT In the process of shredding oil palm leaves, the craftsmen still use manual methods using knives. To be able to help the craftsmen in the process of shrinking oil palm leaves that are faster, save energy, and produce more production, a machine was made to modify the shaved palm sticks. Palm oil kneading machine is a machine used to clean sticks from oil palm leaves. This machine uses …

Abstract To support efforts to develop unmanned fast boat technology in Indonesia. Among the many components of the propulsion system on Unmanned Fast Ships, one of them is the propeller. The propeller is a ship's mechanical propulsion device that accelerates the movement of water towards the rear of the propeller to produce thrust (thrust). In other terms, converting power into rotational for…

ABSTRACT A mixture of used cooking oil and pertalite has not been widely used by people as fuel for stoves. In general, kerosene is used as fuel in the stove, but the price of kerosene is very expensive. This study aims to find alternative fuels to replace kerosene for stoves. In order to grt the best performance of the stove, the treatment of variations in the ratio of used cooking oil-pertal…
ABSTRACT The ultimate goal of this project is to make a Forward topology dc-dc step down converter. The main source of electric vehicle engine propulsion is a 48 volt dc battery. The voltage requirement for electric vehicle accessories requires a voltage of 12 volts. To lower the battery voltage, this is done through a dc-dc converter circuit with a Forward Converter topology which functions t…
ABSTRACT The quality of the inhaled air affects the immune system and human health. If the air that is inhaled is dirty, it can interfere with daily human activities and one way to prevent it is to need a device that can identify and clean dirty air so that the need for clean air can be met and daily human activities will run smoothly. So in this final project, the author designed the Air Puri…
ABSTRACT Chicken eggs are incubated by their parents until they hatch within 21 days. The incubation process is carried out naturally or artificially. The natural process is the process of incubating the eggs by being incubated by the mother until they hatch without human intervention, while the artificial process is the incubation process that relies on human equipment, namely the chicken egg…
ABSTRACT The ultimate goal of this project is to supply the four mosfets that make up the full bridge converter for charging a lithium ion battery.The control is achieved through a DC-DC converter circuit with a Push-Pull converter topology, which is used to convert the input DC voltage into an adjustable DC output voltage. To activate the DC-DC converter circuit, a control circuit is required…
