Abstract

The research was conducted by analyzing the optical fiber attenuation of the DWDM performance in terms of power received on optical fiber communication systems link Padang-Lubuk cone in PT. Telkom Padang. Optical fiber has a very small damping. Therefore optical fibers become the primary choice in telecommunications networks. To improve the transmission quality is better then the use of DWDM technology, DWDM technology is a method to insert a number of channels were transmitted in a single optical fiber. Instruments in this study is the Power Meter and OTDR JDSU MTS-2000 type, the type of cable used G.655 Single Mode type. Link Power Budget method is used to determine the performance of DWDM caused by attenuation based on the value of the received power output receiver. On the link Padang - Lubuk cone highest attenuation occurs in core 1 of 29.742dB with 100.035 km cable lengths, and the core 10 of 31.8 dB with 119.998 km cablelengths. Based on the large fault or attenuation/km core 1 of 0.297 dB/km, the core 10 of 0.265 dB/km and the standard ITU-T was 0.35 dB/km. Value attenuation/km core 1 and core 10 is still in normal conditions and under standard ITU-T 0.35 dB/km. Based on optical fiber attenuation, the results of analysis of the link power budget is the value of Rx is smaller than the value of Rx sensitivity of -27 dBm, it can be said performance DWDM optical fiber communication systems in normal and can be used to operate because the power output can still be accepted by receiver in the device. Keywords:optical fiber cable, optical fiber attenuation, DWDM, link power budget.

Abstract

Today's technological developments are growing rapidly, but there are still jobs that are done manually and semi-manually. This paper aims to develop a control system to coordinate the work of tools using an electric motor, which is very helpful in the process of cutting onions in large quantities and is more efficient in spending production costs because the tool designed is an automatic onion cutter. This research method begins with the collection of materials and data related to onion cutters, production of onion cutters, and testing of onion cutters. The measurement results of the tool show that every component in the automatic onion cutter works well and optimally; the measurement process is carried out properly and thoroughly. This optimal work result is supported by Arduino Uno. The Arduino Uno microcontroller acts as a tool controller. In the main system, the onion cutter is controlled by the Arduino Uno with the Arduino programming language. This automatic onion cutting system will work when the onion you want to cut has been inserted into a cross-section that has been equipped with an ultrasonic sensor, and then the onion cutting process is carried out. Compared with the manual method, the cutting time is almost the same. It's just that the advantages of slicing with this tool, the resulting slices are relatively more uniform. Besides that, another advantage is that it doesn't hurt the eyes of the onion slicer. So that this tool can be used by small entrepreneurs and onion farmers to increase productivity and the community's economy.

Abstract

Antena merupakan salah satu perangkat telekomunikasi yang masih digunakan sampai sekarang dengan tujuan dan aplikasi tertentu. Antena yang ada telah banyak mengalami modifikasi untuk mendapatkan beberapa parameter demi mencapai fungsi yang diinginkan. Pada penelitian ini, dilakukan perhitungan dimensi dan desain antena microstrip dengan pencatuan coaxial-fed yang bekerja pada frekuensi 2.4 GHz. Tujuan penelitian ini adalah untuk melihat pengaruh truncated corner terhadap bandwidth dan return loss pada antena microstrip 2.4 GHz. Pendekatan eksperimental dilakukan untuk melihat optimasi antenna dengan menambahkan truncated corner untuk menambah bandwidth antena. Penambahan truncated corner menggunakan teknik parameter sweep untuk koefisien truncated corner (ptc) dari 0 sampai 6 dilakukan untuk melihat pengaruhnya terhadap bandwidth, return loss, dan frekuensi kerja dari antena tersebut. Hasil penelitian menunjukkan bahwa penambahan truncated corner memberikan pengaruh terhadap bandwidth dimana bandwidth mengalami kenaikan sampai pada nilai tertentu yakni sebesar 1.3 MHz. Selain itu, juga terjadi pergeseran frekuensi kerja antena ke frekuensi yang lebih tinggi dan lebih rendah diikuti dengan perubahan nilai return loss yang didapatkan.Kata kunci : Truncated Corner, Bandwidth, Return Loss, dan Microstrip. Antenna is one of the telecommunications equipment that is still used today for specific purposes and applications. The existing antenna has undergone many modifications to obtain several parameters to achieve the desired function. In this research, the dimensions and design of a coaxial-fed microstrip antenna were calculated and worked at a frequency of 2.4 GHz. The purpose of this study was to see the effect of the truncated corner on the bandwidth and return loss of the 2.4 GHz microstrip antenna. An experimental approach was taken to see antenna optimization by adding a truncated corner to increase the bandwidth of the antenna. The addition of a truncated corner using the parameter sweep technique for a truncated corner (ptc) coefficient from 0 to 6 was carried out to see the effect on the bandwidth, return loss, and working frequency of the antenna. The results showed that the addition of a truncated corner affected bandwidth where the bandwidth increased to a certain value of 1.3 MHz. In addition, there is also a shift in the working frequency of the antenna to a higher and lower frequency followed by a change in the value of the return loss obtained. Keywords: Truncated Corner, Bandwidth, Return Loss, dan Microstrip.
