<p class="Affiliation"><em>Abstrak</em><strong> Seiring perkembangan teknologi yang begitu pesat, robot-robot cerdas bermunculan dan diciptakan untuk memudahkan dan meringankan pekerjaan manusia. Mesin robot yang semakin pesat perkembangannya pada dasarnya membantu manusia dalam beraktifitas sehari-hari sehingga pekerjaan manusia lebih efisien. namun seiring perkembangan itu harus diimbangi dengan sumber daya manusia yang mampu menguasai teknologi tersebut tidak hanya menggunakannya. Paper ini membahas perancangan robot yang dibuat oleh Mahasiswa Universitas Al Azhar Indonesia guna meningkatkan kemampuan dan pengetahuan dalam bidang teknologi khususnya di bidang robotik. Robot yg dibuat ini berfungsi untuk memadamkan api. Robot ini merupakan jenis hexapode, yaitu robot jenis laba-laba berkaki enam yang menggunakan servo dan dijalankan menggunakan Android dan sensor. Namun fungsi pemadam api belum berjalan dengan baik karena servo motor yang digunakan terlalu besar sehingga power pada robot hanya mampu mengangkat ke-enam kaki robot selama dua detik.</strong></p><p><strong><em>Abstract</em></strong><strong>- Along with the rapid development of technology, intelligent robots have sprung up and created to facilitate and ease human work. Robot machines that are increasingly rapidly developing basically help humans in their daily activities so that human work is more efficient. but along with that development must be balanced with human resources who are able to master the technology not only use it. This paper discusses the design of robots made by Students of Al Azhar University in Indonesia in order to improve their abilities and knowledge in the field of technology, especially in the field of robotics. The robot that is made serves to extinguish the fire. This robot is a type of hexapode, which is a type of six-legged spider that uses servo and is run using Android and sensors. But the fire extinguisher function has not gone well because the servo motor that is used is too large so that the power on the robot is only able to lift the robot's six legs for two seconds..</strong></p><p><strong>Keywords<em>– </em></strong><em>Fire robot, Hexapod robot, Arduino, Servo motor<strong></strong></em></p>

Methods FFT (Fast Fourier Transform) is a method for solving discrete signals which method IFFT (Inverse Fast Fourier Transform) is the reciprocal of the FFT method. Basically FFT only used for transformation and must not be separated from the method DFT (Discrete Fourier Transform). DFT is a mathematical transformation method for discrete time signal into a frequency domain. Examples for use of FFT-IFFT such as voice processing, OFDM and others. In this project the author designed the GUI for displaying the FFT and IFFT using LabVIEW. GUI design using Labview will inputed signal infromation or sample as desired and can be changed. From these results we obtained the value of V (amplitude), the value of the frequency and I/O (input/output) can be displayed in a single VI.

<p><em>Abstrak</em><strong>  - Indonesia perlu mempersiapkan masyarakatnya agar tidak terus menerus menjadi konsumen namun menjadi produsen yang bisa bersaing di pasar global. Oleh karena itu, kami mencoba menjawab permasalahan tersebut dengan merangkul para pelajar SMA/SMK dan sederajat agar menyadari betapa pentingnya mempelajari teknologi sedari dini. Langkah awal yang dapat dilakukan adalah melalui pelatihan dasar flip-flop. Pelatihan ini sebagai modal awal membangun sifat kritis terhadap teknologi. Jika kepedulian telah terwujud diharapkan akan membawa perubahan untuk kemajuan IPTEK di Indonesia. Flip flop pada pelatihan ini adalah rangkaian lampu yang dapat menyala secara bergantian atau kedap kedip seperti layaknya lampu hias sehingga bisa memberikan nilai keindahan pada area disekelilingnya. Cara pembuatan rangkaian lampu flip flop ini sangatlah mudah. Namun dibutuhkan ketelitian dan juga ketekunan dalam membuatnya.</strong></p><p><strong> </strong></p><p><strong><em>Kata Kunci</em></strong> – <em>Teknologi, Flip-Flop, Lampu Hias, Seven Segmen</em></p><p><em> </em></p><p><em>Abstract</em> - <strong>Indonesia needs to prepare its society not to continue to be a consumer but a producer that can compete in global market. Therefore, we try to answer the problem by embracing the students of Senior High School / Vocational High School and equal to realize how important to learn technology early on. The first step that can be done is through basic flip-flop training. This training as an initial capital builds a critical nature of technology. If the concern has been realized it is expected to bring changes to the progress of science and technology in Indonesia. Flip flop in this training is a series of lights that can be alternated or alternatively blinking like an ornamental light so that it can give a beauty value in the area around. How to manufacture this flip flop light circuit is very easy. But it takes precision and also diligence in making it. </strong></p><p> </p><p><strong><em>Keyword </em></strong><em>– Technology, Flip – Flop, Decorative Lights, Seven Segmen</em></p>

Theoretical approach to study the influence of temperature of the effective refractive index value for asymmetric nonlinear optical waveguides was developed. Waveguide structures are equipped with linear cladding and substrate. Numerical modeling and calculations were performed to measure the sensitivity of the effective refractive index core thickness for transverse electrical (TE) mode and transversal magnetic (TM) mode. Based on the results, which affect the waveguide refractive index value, we can also adjust the waveguide by varying the temperature value. The waveguide structure is completed by linear cladding and substrate.

FSO (Free Space Optic) is a form of optical technology communication by transmitting light to media free space. In the FSO system, the data transmission can be larger, namely 1-100 Gbps, and this is due to the large bandwidth width. FSO runs at a wavelength of 850 nm and 1550 nm. FSO is usually with a maximum distance of 2-4 km. This paper simulates the FSO optical transmission system using NRZ and RZ line coding in bright and rainy weather conditions. The parameters analyzed are Eye diagram, Optical Spectrum , photocurrent, and received signal power. In the FSO line coding system, NRZ has an eye height value, received signal power and received photocurrent is greater than the RZ line coding at a distance of 1 km and 5 km in bright and rainy conditions. In the trial of this FSO communication system, it is better to use it at a distance of 1 km, because the received signal power is above 20 dBm and received photocurrent is still above 800 mA for NRZ and RZ line coding. This is due to the attenuation value of sunny weather conditions that are smaller between 0.2-3 dB/km, while in rain conditions between 4-17 dB/km.
