ABSTRACT A solar power plant is a renewable power plant that uses energy derived from solar radiation. Solar radiation can be converted directly into electrical energy in a process commonly known as solar cells. Solar panels are also easily exposed to dust on the surface of the panels, which of course also affects the performance of the PLTS. This study aims to determine the effect of pollutan…

ABSTRACT Charcoal is the result of the carbonization process of carbon-containing materials due to decomposition by heat where the charcoal itself can be used as the main ingredient for making graphene. Plasma arc discharge technology has the interesting characteristic that the output power can be controlled easily and precisely by the magnitude of the current. To produce high-voltage plas…
ABSTRACT The payment system at retail stores today generally still uses the traditional cashier system. The cashier must scan the barcodes one by one on each grocery product, so other consumers will have to wait quite a long time if there is only one cashier available. Currently, the self-checkout system method has begun to be developed. Self-checkout system is a facility that allows consumers…
ABSTRACT Busbar is a component in a substation which is a power meeting point or as a power concentration center. During operation, the busbar cannot be separated from abnormal conditions or disturbances. A disturbance to the busbar will have a much greater impact than a disturbance to the conductors. PT. Semen Padang substation has not used busbar protection in its operation because there is …
ABSTRACT Coconut shell charcoal is one of the products that can be converted into graphene using high voltage plasma technology. This study aims to determine whether using high voltage plasma technology with arc discharge method can convert charcoal into graphene and to analyze it using X-Ray Diffraction (XRD) which aims to determine the crystallization structure. The occurrence of shifts and …
ABSTRACT Of the many types of bacteria that exist, Escherichia coli bacteria is one of the bacteria that is often found, it is known that consuming water contaminated with Escherichia coli bacterial microorganisms can be detrimental to humans, including causing diarrhea, vaginal discharge in women and also cardiovascular disease which is one of the causes cause of meningitis in infants. In…
ABSTRACT The load flow study aims to determine, discover and expand the condition of an electrical system. This study conducted in West Area Kasikan for a new powerplant system in a form of gas engine powerplant (PLTMG) 1100 kW for total of 3 units, and additional 500 kW workload in Langgak’s Region which was executed through the Electrical Transient Analysis Program (ETAP) Power Stations 12…
ABSTRACT Currently the use of macro cells with relatively long wireless channels cannot support high bitrates. To overcome these weaknesses multiplying radio access points can be done using transmission media such as Fiber Optic or Free Space Optic. In this research, we analyse the performance of optical communication systems with QAM modulated RF signal input on Fiber Optic and Free Space Opt…
ABSTRACT NAS is a server that uses a special operating system. Raspberry Pi 4 Model B was chosen as the NAS server because it has functions similar to computers in general. The operating system installed on the Raspberry Pi 4 Model B is Openmediavault, which is a system based on Linux and uses the Debian distro. This system can be used for simple solutions that make it easy for people to insta…

This game is usually played as entertainment for the community which is usually played in coffee shops or p…
ABSTRACT The internet network is very important for the community, because currently people carry out all activities in their respective homes. The National Road is a road located in Buluh Kasap Village, East Dumai District, Dumai City. The majority of the population is of lower middle income, some have even been laid off from their place of work, and many children are still in school who need…
ABSTRACT The condition of overloading the power transformer and exposure to an ambient temperature above the standardiwill cause thermaliaging of the insulationion the power transformer, and aging of the thermal insulation will cause a reduction in the life of the power transformer. Based on the fact that abnormal conditions in the power transformer are caused by overloading, it is important t…
ABSTRACT Free Space Optic (FSO) is a high-speed wireless communication system with an easy and inexpensive installation process and has wide bandwidth, high data rate capacity, high security. So that it becomes one way to replace wired optical communication by performing wireless optical communication and has the potential of a transmission system to achieve the ability to multiply users w…
ABSTRACT The water reservoir monitoring system helps the community to find out the water level in the reservoir to avoid overfilling or lack of water in the reservoir when water is needed. This tool is equipped with NodeMcu Esp32 as a control to process sensor data for measuring distances in reservoirs and relay control on motors that are displayed on the telegram as measurement informatio…
ABSTRACT Cloud Storage is a metaphor for the internet, as a storage medium that is often depicted on computer network diagrams. A part from being like a cloud in a computer network diagram, cloud storage in cloud computing is also an abstraction of the complex infrastructure it hides. This cloud-based storage provides a lot of convenience, where data exchange can be carried out without limitat…
