Abstract

A laser rangefinder is a device that uses laser light to determine the distance of an object. The working principle of this laser rangefinder is that the laser beam that is emitted to the object will be reflected back to the rangefinder, and the required propagation time of laser beam will be calculated to get the distance value. In this study, a laser rangefinder system was designed to be used as monitoring of obstacle height between the line of sight of a microwave communication link using a quadcopter, which is used as a top-viewer picture taker. The quadcopter was used as a device to carry the laser rangefinder to measure the obstacle height between the location points of near-end and far-end. The obstacle height reading results were transmitted using a 5.8 GHz wireless transceiver to the monitoring location in real time. The data received were then processed to be displayed in the form of obstacle height graph as a function of the line of sight communication distance. The test results show that the implementation of laser rangefinder technology has an accuracy of more than 90%.Keywords: Line of Sight, Laser Rangefinder, Near-end and far-end, Quadcopter, Obstacle

Abstract

The toll ticket payment mechanism still uses e-toll cards by attaching e-toll cards to the reader at the toll gate. This has several drawbacks, including the driver having difficulty sticking the cards. At present, a device has emerged to access the toll road without attaching a card known as the OBU. However, this device has a pretty expensive price. Therefore, an access system in and out of toll roads is made without using a card. With this system, users only need to register license plates in a database and there are applications that will also be used for payment, and as trip monitoring. By using ultrasonic sensors and image processing methods, vehicle license plates that will enter the toll road can be detected. The test results are known to distance of the camera to the number plate to read correctly as far as 2 - 3 meter and when the distance of the camera to the number plate as far as 4 m, shows the wrong reading of the license plate. Ultrasonic sensor testing showed no failure in ten attempts. Ultrasonic sensors are used to detect the presence of objects vehicles when vehicles enter or exit the toll road

Abstract

The growing number of internet applications and their users can affect the quality of the internet, each application has different traffic needs. In addition, bandwidth management can also lend bandwidth that has been allocated in accordance with its priorities in order to optimize existing bandwidth usage. Regulating and limiting internet bandwidth usage is indeed an important thing when our internet connection is limited. We need to limit the bandwidth quota of each user connected to the Mikrotik Router. In Mikrotik Router itself, there are features that can limit bandwidth, namely simple queue and queue tree. In the use of VoIP services, bandwidth management is required to manage traffic on the network, the appropriate bandwidth settings can optimize the speed of data transmission. Looking at the internet needs, this research designs an implementation of bandwidth management using routerboard, which will be applied to IP-PBX and use raspberry pi as a server. The results of the research on bandwidth management implementation in simple queue and queue tree is each able to serve 6 users with PCMU codecs, from the test obtained packet loss value of 0.00% from 3 clients, and jitter has an average value of 167.37% from 3 clients.

Abstract

Voice over Internet Protocol (also called  VoIP,  IP Telephony,  Internet Telephony  or  Digital Phone)is a   technology that enables remote voice conversation through internet media. Voice data is converted into digital code and streamed over a network that delivers data packets, rather than through a regular analog telephone circuit. In VoIP  communication,users make telephone connection through a terminal in the form of a PC or a regularphone. By calling voip,  manyadvantages that can be taken in terms of costare obviously cheaper than traditional phone rates, because IP networks are global. IP Phone can be added, moved and changed. This is because  VoIP can be installed in any ethernet and IP address,unlike conventional phones that must have their own port in Sentral or  PBX  (Private branch exchange). In this study implementing connectedness between servers using single board computer   installed  elastix operating system that aims to implement  prefix for between servers and use some audio codecs. The results of telephone research using prefix and without prefix as many as 6 clients or 3 pasng calls simultaneously the highest packet loss  value in codec speex   with prefix  of 2.34%. The  highest bandwidth value used is with pcmu prefix codec with an average of 82.3 Kbps and without prefix 79.3 Kbps.

Abstract

So far, there are many manual methods used to determine the freshness of chicken eggs, for example utilizing sunlight or a flashlight to illuminate the eggs in a dark place and then look at the contents of the chicken eggs for sorting. The same process has also been carried out by breeders or grocery traders to sort chicken eggs based on their quality. The purpose of this research is to make a chicken egg detection device using a conveyor, LDR (Light Dependent Resistor) sensor, lamp, LCD (Liquid Crystal Display), servo motor, esp8266 module and Arduino Mega Microcontroller as a processor. The performance results of this device affect the condition of the egg chicken to be detected. The results of this study, this tool has an accuracy of 95% in detecting egg quality, where the LDR sensor shows an ADC value of <260 for indicators of good egg quality, while ADC values ??of more than> 26 for indicators of poor egg quality. Once the eggs are detected, the servo will direct good quality chicken eggs to the right and poor quality chicken eggs to the left. Delivery of notifications and information to the website application is done online and in real time, and a good internet network is required. The time it takes for the system to transmit data from the time the system detects an egg until it appears on the website is 20 - 50 ms, according to ITU-T standards

Abstract

Voice over Internet Protocol (VoIP) merupakan teknologi komunikasi yang mampu melewatkan layanan dalam bentuk pesan, suara dan video ke dalam jaringan Internet Protocol (IP) sehingga mampu melakukan hubungan telekomunikasi antar pengguna yang terhubung dalam jaringan komputer. Untuk membangun teknologi VoIP dibutuhkan sebuah server yang merupakan perangkat lunak jenis SIP proxy server yang dipasang pada personal computer sebagai IP PBX dan berfungsi sebagai penyambungan, pengendalian, dan pemutusan hubungan telepon. Pada penelitian ini digunakan single broad computer yang disebut perangkat komputer mini sebagai alternatif untuk mengganti komputer personal sebagai server VoIP, dengan spesifikasi prosessor quad-core dan memory1GB LPDDR2 mampu memberikan akses sistem operasi dengan versi terbaru untuk dapat menghasilkan kualitas komunikasi lebih baik menggunakan mini pc sebagai alternatif IP PBX. Pada penelitian ini dirancang sebuah sistem komunikasi server VoIP IP PBX menggunakan sistem operasi linux elastix. Hasil pengukuran diketahui bahwa saat dilakukan komunikasi VoIP memiliki delay yaitu 4,87091 ms dan 17,4576275 ms sangat baik atau istimewa sesuai standart ITU-T yaitu <150 ms. Untuk hasil jitter pada pengukuran masuk dalam kategori bagus dengan peak jitter tidak lebih dari 75 ms yaitu sebesar 18,265 ms. Untuk packet loss pada keseluruhan gedung memiliki nilai yang sangat baik dengan jumlah paket data yang hilang per detik sangat sedikit yaitu 0,71% atau hampir tidak ada. Dari hasil pengukuran throughput diperoleh nilai sebesar 0,2747 Mbit/sec. Berdasarkan teori, semakin besar nilai throughput pada suatu jaringan maka delay yang dihasilkan semakin rendah.
