  • Optimalisasi Stand-Alone Photovoltaic System dengan Implementasi Algoritma
           P&O-Fuzzy MPPT

    • Authors: Dimas Juniyanto, Tatyantoro Andrasto, Suryono Suryono
      Pages: 1 - 10
      Abstract: The need for electrical energy continues to increase every time. Concerns about the depletion of fossil energy reserves encourage the acceleration of the development of renewable energy use. One of renewable energy is the solar energy. Due to the irreversible irradiation conditions, it takes controls to keep the solar panel's maximum power. The most widely in Maximum Power Point Tracking (MMPT) is Perturb Algorithm and Observe (P&O) but P&O Algorithm has deficiency of oscillations when steady state and MPP trace errors when irradiation changes rapidly. In this paper proposed P & O-Fuzzy algorithm is a modification of conventional P & O to improve the efficiency of solar panels. This research uses Matlab for simulation and hardware implementation using microcontroller Arduino Uno and buck converter topology. The result of simulation and hardware implementation, conventional P & O has an average efficiency of 85.03% while MPPT modification with P & O-Fuzzy algorithm can improve MPP tracking efficiency with 89.67%.

  • Analisis Karakteristik Elektrik Bentuk Geometri Jalur PCB Menggunakan
           Pendekatan Finite Element

    • Authors: Putut Son Maria, Elva Susianti
      Pages: 11 - 17
      Abstract: Some Electronics Computer Aided Design (ECAD) softwares have provided several track shapes to design a Printed Circuit Board (PCB), such as right angle, rounded and trapezoidal. However, it is quite difficult to find scientific literature that can be used as a guide which explains and compiles directly about each character of the geometry. This study aims to analyze and to observe the electrical characteristics of the geometry shape on the Printed Circuit Board (PCB) path by using the finite element method. Each PCB path shape is modeled according to its geometry and physical properties, then calculated for its electrical quantity and be observed for its performance at given current. Simulation and numerical calculations showed that the shape of trapezoidal and rounded geometry have lower resistance and planar inductance of 6.8% and 7.39% respectively than the right angle shape.

  • Analisis Metode Certainty Factor pada Sistem Pakar Diagnosa Penyakit THT

    • Authors: Khairina Eka Setyaputri, Abdul Fadlil, Sunardi Sunardi
      Pages: 30 - 35
      Abstract: There are two factors that cause a disease, called  Congenital and Acquired. Congenital refers to a disease a person is born with, while Acquired refers to a disease acquired after a person was born such as infection, trauma, and neoplasm. The infected person will sometimes require information on the disease before going to the doctor or a hospital. Such information may be found from a system which receives input on the symptoms and gives a clear information on the corresponding disease. This may be achieved via a system of experts, in which the expert refers to an ENT (Ear, Nose, and Throat) specialist. Such information is hoped to provide a solution on the disease. The system of ENT specialists designed and research in this paper used the certainty factor method. The method will overcome the uncertainty in decision making depending on the symptoms described by the user. This paper is successfully applied certainty factor method used as an instrument of decision making in the system of ENT specialists. The system is web-based, enabling the user to access and choose the symptoms of the disease as well as acquiring information on ENT diseases  easly.

  • Analisis Link Budget Penyambungan Serat Optik Menggunakan Optical Time
           Domain Reflectometer AQ7275

    • Authors: Tio Hanif Yanuary, Lita Lidyawati
      Pages: 36 - 40
      Abstract: An optical fiber is a high-speed telecommunication transmission medium. Principally, an optical fiber is made of a very fine glass fiber material, which is able to transmit light waves using light reflection method on the surface of the fiber optics core. An underground installation of the fiber optics makes this device robust from external interferences. However, the fiber optic cable performance should always be checked to maintain performance during data transmission process. One way to test fiber optics cable performance is by using an Optical Time - Domain Reflectometer (OTDR) device. This device sends a light wave from one point of the fiber optics cable. The light wave then returns when reaching the other point of the fiber optic cable while carrying some measurement parameters especially the physical length and attenuation of a fiber optic cable. The evaluation of the fiber optics cable performance requires the preparation, installation, and configuration of the OTDR. In this paper, we conducted evaluation on the performances of fiber optics cable. The data generated by the performed evaluation indicated an occurring attenuation on the fiber optics cable along 64.402 km of its lengths.

      Abstract: Nowdays, along with the  development of electronics and computers, the crime rate increases  rapidly.  today almost all systems and security tools are using electronic devices such as computers and  microcontrollers. Every electronic device always has weakness, such as camera needs the light to capture images, Passive InfraRed (PIR) sensor only has ability for human body temperature detection, Short Message Service (SMS) which its services depend on prepay credit and cellular operator signal range.  Based on the problem, a radio-based doppler radar detection tool was developed using RCWL 0516 module. In this research will be discussed the use of RCWL 0516 sensor as main module to detect the movement of the object by measuring the microwave wave value that displayed on the user gadget by using Blynk application. The digital communication is used and implemented on Arduino Uno microcontroller. The data is sent and will be displayed on the gadget through Blynk application in the form of graph in real time and connect to the internet using ESP8266 as a connection receiver. The results obtained that the RCWL 0516 module has a better accuracy level in detecting movement than other motion detection sensors such as PIR sensors and ultrasonic sensors.
