Abstract

Seiring dengan perkembangan teknologi informasi khususnya pada layanan multimedia seperti video, voice dan data untuk meningkatkan pelayanan pada pelanggan dan menjawab tuntutan masyarakat akan layanan multimedia, maka digunakanlah jaringan Digital Video Braodcasting Cable (DVB C). DVB C merupakan salah satu teknologi jaringan kabel yang dibentuk dari kombinasi jaringan optik dan koaksial. Pada penelitian ini diharapkan dapat memberikan layanan akses broadband kepada pengguna untuk layanan TV kabel, internet, video on demand, dan layanan berbasis multimedia. Dari perencanaan digunakan lebar bandwidth untuk downstream sebesar 750 Mhz dan untuk upstream sebesar 60 Mhz. Berdasarkan perancangan maka kebutuhan yang dapat dilayani untuk downstream yaitu TV digital (48 MHz), TV analog 80 MHz, Video On demand (72 MHz), dan Internet 16 MHz. Total Bandwidth untuk upstream yaitu 4,6 MHz. dengan Total pelanggan 140. Berdasarkan hasil perancangan dengan menggunakan software cabel tools, perangkat yang dapat digunakan yaitu Splitter 2 way, Amplifier, TAP 4 way dengan redaman 23, 20,dan 17 dB dan Tap 8-17, 8-11. Performansi hasil rancangan telah memenuhi target level sinyal minimum dan maksimum untuk masing-masing Tap.

Abstract

The development of unmanned aircraft technology encourage for new infrastructure and development in the tourism sector. Challenges for the development of tourism in Gunungkidul Regency included the development of tourism and cultural villages, access roads to tourism objects, and coastal tourism objects. So, the community service partner was the Gunungkidul Regency Tourism Office. The main objective in this community service activity was to increase knowledge and skills of UAV (Unmanned Aerial Vehicle) to support the development of tourism facilities, particularly in aerial photo taking. The target achieved at this stage was to increase knowledge about UAVs and the ability to control UAV aircraft for taking aerial photographs to support tourism in Gunung Kidul. Increasing ability to control UAVs was done through practice. While increasing knowledge was done through explanation about UAVs. This activity has been able to achieve the expected goals and targets, so that partner can recognize and be able to control the UAV.

Abstract

Technological developments have opened up a new infrastructure in communication for transmitting audio data. This is evidenced by the large number of communication media, both wired and wireless. So that it raises new methods for sending audio data, one of which is using Visible Light Communication (VLC). VLC is a communication system for transmitting and receiving data using the visible light wave spectrum between 375 nm - 780 nm. In this research, audio data communication utilizes the brightness of the LED light. The transmitter and receiver use an LED component as a transducer which is then sent to the data processing circuit. From the data processing circuit then sent to the audio amplifier circuit. From the test results it can be shown that this system can transmit audio data. Based on the LED color test, Green produces the highest output voltage of 1.32 Volt. The angle limit that can be detected by the photo diode is at an angle of 70° with a measured voltage of 100mV and the resulting sound intensity of -32.541dB.

Abstract

As we know, digital systems have been used in everyday life or in industry today because they are more useful than analog systems. Because it is important to develop digital systems, many new digital devices have been designed in complex ways. Some of these devices are called microprocessors, microcontrollers or microchips. It is very important to have very high speed performance in all devices. In this study, a tool was designed, namely, the Arichmetic Logic Unit or it can be called ALU. An important part of Field Programmable Gate Arrays or also known as FPGA, ALU generally has functions to perform arithmetic and logic calculations. Based on the results of the testing of the tools that have been carried out, it can be concluded that the design of the Arichmetic Logic Unit on the Spartan 2 FPGA. with the arithmetic operations performed are the ADDER (A + B) and SUBTRACTOR (A - B) operations, the logical operations performed are the OR (A OR B) and AND (A AND B) operations. It has been simulated and implemented with results that match the specifications of the design.

Abstract

ABSTRACT:Electricity has become a basic necessity for everyone. Household appliances using electricity have become a basic human need today. Monitoring equipment is needed to know how much power, energy, used and the estimated cost to be paid. The tool designed for this monitoring system uses a PZEM-004T sensor, the platform Ubidots and NodeMCU. The PZEM-004T sensor functions to measure the voltage, current, power, power factor, and energy contained in electrical loads. And NodeMCU is needed as a microcontroller. The results can be displayed on the platform Ubidots and the 16x2 LCD used. The test results obtained through measurements using the PZEM-004T sensor for designing a prototype energy monitoring system have a voltage accuracy value of 98.94%, 99.18% current, 98.87% power, 98.44% power factor, and 97 electrical energy consumption. , 89%. In household electrical appliances (led lights, televisions, fans, ricecookers, and laptop chargers) the results of electrical energy consumption in a month are 43.56 kWh and the estimated cost is Rp 114.781.52.ABSTRAK:Listrik sudah menjadi kebutuhan dasar setiap orang.
