ABSTRACT Catfish is a type of fish that is widely cultivated in Riau Province. This fish has a high growth rate and is not difficult to breed. However, after observing several fish farming ponds, it was found that the fish have different appetites at certain temperatures. Feeding should be done effectively and efficiently to save costs and prevent the pond water from becoming toxic to the fish…
ABSTRACT In aquaculture activities, it is important to pay attention to water quality because water is the main medium for fish survival. The quality of the water used must meet the requirements needed for fish life, both in quantity and quality. One of the important aspects of water quality parameters is pH and dissolved oxygen concentration. The pH balance in the pond greatly affects the gro…
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 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…
ABSTRACT Currently, Indonesia has installed 20 airborne radar points and 11 maritime radars. However, not all areas in Indonesia can be reached by this radar. With the limited number of existing radars and the large number of areas that must be monitored, a portable radar such as a man-pack radar is needed. Man-pack radar is a radar that can be used on a mobile basis and can be used in remote …
