Abstract

The main objective of this thesis is to demonstrate the benefits of the analysis of Power Spectrum Density (PSD) to observe the change of the electric field at intermediate negative lightning cloud to ground (CG) and terminology-intermediate breakdown-leader (BIL) before turning the struck first. Analysis was done on data 74 occurrence of lightning in the city of Padang, with terminology BIL. Time domain analysis time – frequency of use applications Short Time Fourier Trasnform (STFT), then the results of the analysis time domain – frequency domain analysis compared with the time. The basis of the use of the STFT is the calculation of Spektogram.  Time domain analysis of results time – frequency domain analysis against the difference obtained by time, where for data with sampling rate 1 MS/s (low resolution) in the domain of time, does not happen much changes compared data with sampling rate 25 MS/s (high resolution), high resolution spectrum due to clearer spectrum amplitude frequency. Different the results of the calculation phase BIL with time domain data will look on the lightning with a time limit of occurrence of short or Intermediate phase on the value of the voltage E smaller, because it forms the lower wave recording-amplitudo, so can be seen clearly the difference phases of BIL is happening. Keyword: Preliminary Breakdown, Intermediate Duration, phase based on Power Spectrum Density BIL.

Abstract

Multilevel Inverter (MLI) is a converter that converts DC power source into AC power source with voltage output more than 2 levels. The conventional 5-level Multilevel Inverter Topology that is developing today generally uses eight power switch components. In this paper, research Topology multilevel inverter 5 levels was conducted by reducing the power switch components into four pieces and assisted by two diode clamps and capacitor as voltage coupling. PWM (Pulse Width Modulation) technique used to utilize multicarrier modulation. Simulation testing with MATLAB conducted has been verified with the results of hardware tests where the output voltage shows similarity of shape at the output voltage MLI 5 levels. The results and discussion of the proposed topology can provide economic benefits from the use of the number of power switch components (MOSFET) compared to conventional 5-level MLI topology.Keywords : Multilevel Inverter, PWM, 5 Level

Abstract

Programmable logic controller (PLC) can be programmed for various purposes, one of which is to design a fire extinguishing system, by assembling several components of PLC, solenoid, springkle, powersupply ,adapter ,smokedetector, heatdetector, pilotlamp, pushbutton, relay, selector switch. design the program settings to detect smoke and high temperatures that occur in the event of a fire. if the sensor detects smoke and high temperature, the sensor will give a signal to the plc to turn on and activate all working components and extinguish the fire.

Abstract

Pemanfaatan pembangkit listrik tenaga air skala kecil dapat diterapkan didaerah terpencil yang ketersediaan air melimpah dan tidak terjangkau aliran listrik dari Perusahaan Listrik Negara dengan. Prototype Pembangkit Listrik Tenaga Pikohidro dibuat untuk modul belajar bagi mahasiswa agar dapat memahami proses terbangkitnya listrik dari salah satu jenis pembangkit listrik yang tersedia. Prototype ini dibuat menggunakan generator arus searah (DC) dan keluarannya di konversikan menjadi arus bolak balik (AC) agar dapat digunakan untuk peralatan rumah tangga. Komponen-komponen pembangkit ini dirancang dari peralatan yang sederhana, sehingga hanya bisa dibebani sesuai kapasitas dari generator yang digunakan. Tegangan keluaran generator yang dihasilkan adalah 18 Volt tanpa beban dan 12 Volt disaat diebani sebesar 10 Watt dan 20 Watt
