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

Pencarian pada database yang biasa dilakukan mahasiswa hanya mampu mencari judul yang sesuai berdasarkan kata kunci yang diinputkan, misalnya, jika kata kunci yang dimasukkan adalah “sistem cerdas” maka akan ditampilkan semua dokumen yang mengandung kata “sistem cerdas” namun sistem tidak bisa mengukur mana dokumen yang paling mirip. Untuk dapat melakukan pencarian berdasar substansi yang paling mirip, terdapat teknologi yang disebut information Text Retrieval. Dalam penelitian ini akan dikembangkan suatu sistem temu kembali informasi judul tugas akhir dan perhitungan kemiripan dokumen menggunakan vector space model. Sistem secara otomatis akan melakukan indexing secara offline dan temu kembali (retrieval) secara real time. Proses retrieval dimulai dengan mengambil query dari pengguna, menerapkan stop word removal sehingga dihasilkan keyword yang compaq tetapi dapatmewakili query tersebut, kemudian sistem menghitung kemiripan antarakeyword dengan daftar dokumen yang diwakili oleh term-term di dalam index. Dokumen akan ditampilkan diurutkan berdasarkan dokumen yang paling mirip.Dari hasil pengujian terlihat ketika keyword “android” dimasukkan maka akan tampil empat dokumen yang diurutkan sesuai tingkat kemiripannya, yaitu docId 3 dengan tingkat kemiripan 0.9512, docId 4 dengan tingkat kemiripan 0.5020, docId 2 dengan tingkat kemiripan 0.2671, docId 8 dengan tingkat kemiripan 0.1522.

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

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.

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%.

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

IP Phone is a Voice over Internet Protocol (VoIP) device that can transmit voice using IP. From communication between IP Phones there are waveforms of input and output information signals, the response of voice amplitude to changes in voice frequency and delay value from time shift at the beginning of the wave period of the input and output information signal using the Transmission Test Set and Oscilloscope measuring instruments to determine the character of the sound quality in communication between IP Phones according to the parameter test results. The system test results are that the waveform of the input and output information signal at the sound frequency has a sine wave shape. However, the output waveform of IP Phone A with a frequency of 300Hz to 1100Hz and IP Phone B with a frequency of 300Hz to 1300Hz is distorted, then from the results of the Peak to Peak wave is known to have a voltage gain, that is, the greater the frequency value at the input, the smaller the value of the resulting voltage gain.
