Design of Two-Wheeled Vehicle Access System Using E-KTP and Google Voice Media Based on Arduino Uno
No full text44 HalamanKendaran bermotor yang masih diakses secara manual dan pengamanan yang
menggunakan kunci ganda seperti gembok kurang efektif dan efisien. Hal ini
memungkinkan orang lain dapat mengakses kendaraan pribadi dengan mudah
tanpa seizin pemilik kendaraan .Berdasarkan penjelasan tersebut dibutuhkan suatu
alat dengan sistem yang membantu pemilik kendaraan mengakses kendaraan
tersebut supaya setiap orang tidak sembarangan mengakses kendaraan tanpa seizin
pemilik kendaraan tersebut . Pada penelitian ini dibuat suatu sistem akses
kendaraan yang memiliki dua akses berupa E-Ktp dan suara dengan
mikrokontroller arduino uno sebagai pusat pengolahan utama. Kendaraan hanya
akan hidup jika diakses menggunakan E-Ktp dan juga menggunakan perangkat
android melalui aplikasi yang telah dibuat berupa perintah dari tombl dan media
google voice. Apabila kendaraan diakses dengan cara lain atau secara paksa maka
kendaraan akan tetap off dan alarm akan berbunyi sebagai tanda peringatan
indikasi pencurian. Metode pelaksanaan kegiatan ini terdiri dari bebrpa tahapan
yaitu, observasi awal, perancangan flowchart, perancangan rangkaian, proses
pembuatan alat,dan pengujian alat. Kinerja sistem akan diuji fungsinya sesuai
dengan flowchart yang telah didesain. Hasil pengujian juga berupa data
pengukuran pada masing-masing komponen pada setiap kondisi pengukuran yang
dilakukan. Motorized vehicles that are still accessed manually and security that uses multiple
keys such as padlocks are less effective and efficient. This allows other people to
access private vehicles easily without the permission of the vehicle owner. Based
on the explanation, a tool with a system that helps the vehicle owner to access the
vehicle so that everyone does not carelessly access the vehicle without the
permission of the vehicle owner. In this study a vehicle access system has two
accesses in the form of E-Ktp and voice with the arduino uno microcontroller as
the main processing center. Vehicles will only live if accessed using E-KTP and
also use an Android device through an application that has been made in the form
of commands from the button and Google voice media. If the vehicle is accessed
by other means or by force the vehicle will remain off and the alarm will sound as
a warning sign of theft. The method of carrying out this activity consists of
several stages, i.e., initial observation, flowchart design, circuit design, process of
making tools, and testing tools. The performance of the system will be tested for
function in accordance with the designed flowchart. The test results also in the
form of measurement data on each component in each condition of the
measurements made

No full textNonJinear load has non-sinusoidal wave form because it has been distorted by
harmonics culrent, non linear load in personal computer (PC) one the causes of
harmonics which can cause the quality of electric power to be worse. The research used
simulation method of single tuned filter as the filter used to reduce harmonics caused by
PC dual core using 15 inch LCD monitor and printing machine. By using measurement
device, power quality analyzer fluke SW43W, it is found that PC of D brand, which has
the biggest IHDi in the second order, is 0.469 ampere, the fifth order is 0.360 ampere,
the seventh order is 0.226 ampere, and the ninth order of 0.103 ampere. The Result of
the simulations, using passive single tuned filter, shows that the decrease of harmonics
currcnt value in thethird order is 0.331 ampere, the fifttr order is 0.0254 ampere, the
seventh order is 0.159 ampere, and the ninth order is 0.072 ampere, there is also the
decrease of harmonics current in other orders. The passive single tuned filter being used
with C value is 9,99 pf, L value is 0,021 H, and R value is 0.46 which can reduce [HDi
from l0% - l5o/o whith the decrease of IHDi order up to the 49fr order value. The bigger
the value of the used capasitor the closer the IHDi wave to sinusoidal, and it even
becomes sinusoidal.67 HalamanTesis Magiste

The research of efficiency analysis on the components of solar power generation systems aims to determine the efficiency of PLTS system components, namely the efficiency of the solar charge controller (SCC), the efficiency of the inverter and the efficiency of the conduit between the battery and the inverter. The method used is an experimental method that designing a solar home system and measuring the quantity of electricity in each component of the system. The equipment used is a 2000 wp capacity solar panel, a 3000 watt inverter, a 60 ampere solar charge controller and a 400 Ah 24 volt battery. The results showed that the average solar charge controller efficiency was 80%, power losses of 20% occurred due to the limitation of the voltage and current at the SCC output to protect the battery from overvoltages and currents from the photovoltaic module. The results of the research show that the power wasted due to the protection of this SCC varies from 32 watts to 239 watts on the photovoltaic input power of 149 watts to 1239 watts. The average efficiency of an inverter is 84% and fluctuates from 71% to 97%, 71% efficiency occurs at a load of 38 watts while for an efficiency of 97% occurs at a loading of 277 watts. The average cable efficiency is 96% with fluctuations in cable efficiency because loading only 2% and This fluctuation is more stable than the fluctuation of the efficiency of the inverter and SCC, which is 26% eac
