Abstract

Problems that often occur in the selection of goods, there are still many industries that make convey-ors as senders only without a selection process. The purpose of this study was to make a high-variable item selection prototype tool using an ATMega 8535 microcontroller. It was found that the prototype goods se-lection tool was based on a high ATMega 8535 microcontroller with a maximum working conveyor. Con-veyor 1 will move if there is an item or object that is left in front of conveyor 1 and stops the goods at the end of the conveyor 1. Conveyor 2 will move if the photodiode sensor has detected the items on the convey-or 1. All tests are performed properly. The photodiode sensor works well to measure the height of objects or items. Further improvements with more complex development prototypes that can be applied to actual industries and factories. This tool can only measure the height of the item from what can be developed or the weight of the item.

Abstract

One way to increase service coverage of telecom operators such as PT. Smartfren is by adding or building new Base Transceiver Stations (BTS). To determine where to place the new BTS, there are several criteria and sub criteria that must be considered. Incorrect choice of criteria and sub criteria or lack of data can cause the new BTS to be built in a less precise location thus the service coverage will not be optimal. Based on that consideration, a decision-making system application to determine BTS location is created using Fuzzy AHP method with VB and MySQL applications. The outcome of this application is a list of area, in several regencies, from the highest to the lowest score of BTS location based on the selected criteria and sub-criteria. It helps the user in knowing the most appropriate location for the placement of PT. Smartfren?s new BTS. [TURNITIN 19%, 22022017]

Abstract

Kemajuan teknologi komunikasi, dikembangkan sistem D-MIMO (Distributed MIMO) yang sebelumnya telah digunakan sistem C-MIMO (Conventional co-located MIMO). Sistem C-MIMO menyebabkan penggunaan spektrummenjadi efisien, daya pancar berkurang, dan kapasitas kanal meningkat.Dengan sistem D-MIMO jarak antara pemancar dan penerima dapat diperpendek, macrodiversity dan adanya daerah cakupan layanan. Pada tulisan ini akan diteliti tentang kapasitas kanal dan Bit Error Rate (BER) pada variasi spasial daerah cakupan. Penelitian tersebut dilakukan pada kapasitas kanal teoritis dan BER dengan teknik waterfilling.Kapasitas kanal dan kinerja BER pada sistem D-MIMO pada variasi spasial daerah cakupan tergantung dari konfigurasi sistem D-MIMO. Lokasi penerima yang dekat port antena pemancar mempunyai kapasitas kanal yanglebih besar tetapi memiliki kinerja BER yang lebih buruk.

Abstract

WLAN has been implemented widely, including in public area and government office. Badung Regency office has got benefit from the technology in applying its e- government services. However the WLAN performance in term of its QoS has not been evaluated after its installation. Then its delay, packet loss, throughput, and jitter were measured using Ekahau Heatmapper, Axence Nettols, Wi-Fi Analyzer, and Ubiquiti Unifi. The WLAN coverage area was calculated and analyzed. Generally, the performance is good. However there are areas in all 12 buildings in the offices that are needed more access points.

Abstract

Universitas Dhyana Pura (Undhira) merupakan perguruan tinggi swasta yang memanfaatkan teknologi informasi dalam mencapai hasil optimal. Hasil observasi masalah yang dihadapi tentang pengelolaan bandwidth tidak terkelola dengan baik. Penelitian ini bertujuan untuk menganalisa Quality of Service (QoS) dengan parameter-parameter throughput, delay, packet loss, jitter dan bandwidth dengan metode Class Based Queuing (CBQ) sebagai metode antrian yang mengatur pemakaian bandwidth yang diberikan setiap client. Pengukuran tingkat kepuasan pegawai juga dilakukan dengan menggunakan metode Customer Satisfaction Index (CSI). Hasil penelitian ini menampilkan metode CBQ merupakan metode manajeman bandwidth dalam melimitasi bandwidth pada client yang krisis bandwidth sehingga dapat meningkatkan kepuasan pegawai dalam menggunakan layanan internet dalam proses pelayanan bagi mahasiswa.  Kata Kunci? Manajemen Bandwidth, CBQ, Parameter QoS, Customer Satisfaction Index (CSI).

Abstract

The Internet has become something important in the communication development. One communication facilities on the Internet is the Internet relay chat or known as chat. Chat applications in real time is often misused for the purpose of spreading the virus, promotions, and other interests known as spam. Spamming is the sending of unwanted messages by someone who has a chat account. This causes the chat account feel uncomfortable with the condition. Based on these problems this research create a chat application that can filter messages or spam filtering by applying text mining. Spam filtering process can be done in two phases: text pre-processing and analyzing. These two phases are carried out to calculate the weight (W) of connectedness with the word spam messages. Based on the results of tests performed on chat applications by applying text mining to perform filtering on spam messages generate the level of accuracy of 91.41%.
