Abstract

Pengawasan terhadap penggunaan teknologi informasi sangat diperlukan terlebih semakin berkembangnya ilmu tentang pembuatan virus, worm, atau spyware. Memasang antivirus bisa juga menjadi solusi untuk mencegah virus masuk ke dalam jaringan atau sistem komputer. Tetapi antivirus tidak bisa melakukan monitoring terhadap aktivitas user contohnya aktivitas keyboard. Keylogger adalah perangkat lunak yang mampu merekam segala aktivitas keyboard. Keylogger harus diinstal terlebih dahulu terhadap target komputer (client) yang akan direkam aktivitas keyboard-nya. Kemudian untuk mengambil file hasil rekamannya, file log, harus mempunyai akses fisik ke komputer tersebut dan hal ini akan menjadi masalah jika komputer target yang akan dimonitoring cukup banyak. Metode control keylogger-spy agent dengan memanfaatkan teknologi spyware menjadi solusi dari masalah tersebut. Spy agent akan secara aktif merekam aktivitas keyboard seseorang. File log yang dihasilkan akan disimpan didalam cache-nya sehingga tidak akan menimbulkan kecurigaan user dan tidak perlu mempunyai akses fisik jika ingin mengambil file lognya. Control keylogger dapat menghubungi spy agent mana yang akan diambil file lognya. File log yang berhasil diambil akan disimpan dengan baik di komputer server. Dari hasil pengujian lima komputer yang dijadikan target spy agent semuanya dapat memberikan file log kepada control keylogger.

Abstract

Programable logic control (PLC) is a versatile microprocessor control designed to meet practical demands in industry such as in the automatic field. In the automatic field serves as a substitute for an electro mechanical system that is to replace a series of series of relays found in conventional process control systems. Therefore, in this thesis, a research on Design (PLC) Programable Logic Controller Based on PIC16F877 Microcontroller as Learning Media has been conducted. This Micro PLC consists of a minimum system PIC16F877 microcontroller circuit. Micro PLC testing only takes a few sample cases such as I / O (input output) testing of logic gates, counter testing and timer testing. How to upload a ladder diagram to a micro PLC via a computer using the K150 programmer and Microbrn software to upload the program to a micro PLC so that the input and output modules can work according to the ladder diagram programming that has been made. From the results of micro PLC testing can be used as a PLC learning media

Abstract

Water is a source of life for all living things. However, currently the amount of clean water available is very limited so that it is not comparable with the increasing growth of the world's population. The saving effort that can be done is to make the best use of water. One of them is by saving bath water by controlling the water level in the water reservoir. In this final project, an automatic faucet is designed using an ultrasonic sensor, namely a sensor that will detect the presence of an object and remove or turn off water automatically with the main actuator using a servo motor. In filling the water reservoir to prevent water from overflowing, an ultrasonic sensor is used which will automatically fill when the water volume distance is not within the specified range and will also automatically stop filling when it is within the specified range. So that no more water is wasted due to user negligence.

Abstract

Based on transformer loading at GI 70kV Babakan which is already 80% high bigger than capacity 30 MVA by reason there is a need for additional power supply for industrial development, one of which is the addition of PT. Longrich Indonesia for 25 MVA. With the existing condition of transformer loading at GI 70kV Babakan is currently unable to meet the power supply needs and the construction of GI 150kV Kanci is still in progress, therefore the installation of a mobile transformer at GI 70kV Babakan is intended to meet the need for additional power supply. In this study, simulating Electrical power in GI 70kV Babakan uses the ETAP Power Station 12.6 software and compares it with the results of manual calculations. Installing a Mobile Transformer with a capacity of 30 MVA at GI 70kV Babakan can increase the MVA capacity at GI 70kV Babakan so that it can meet the need for additional power supply, With the load on the mobile transformer and the daytime loading history of 48 MW and the highest load reached at 61 MW, the Mobile Transformer can be loaded with a maximum of 25 MVA. And transformers are still able to supply the area properly so there is no overload. and increase revenue through the sale of electricity.

Abstract

Absence is an activity of reporting and recording attendance in an institution, based on how it is used, the manual attendance system carried out in tertiary institutions requires students to fill out an attendance form with a signature during lectures. These deficiencies can be overcome by utilizing technology combined with the RFID system. An attendance system using web-based RFID is a system that utilizes RFID (Radio Frequency Identification) technology to record individual attendance. This system is designed by utilizing hardware in the form of RFID readers and tags, as well as software and network infrastructure. The software used in this attendance system will receive attendance data from the RFID reader and store it in a database. The attendance data can be accessed through a web interface that can be accessed by administrators or authorized users. This web interface will display individual attendance information, such as date, check-in time, and check-out time. In addition, the system can also provide periodic attendance reports or upon request. This web-based RFID attendance system provides convenience in recording individual attendance. Users no longer need to use manual methods such as attendance cards or attendance lists. By using RFID tags, the process of recording attendance can be done automatically and efficiently.

Abstract

The need for renewable energy is urgently needed at this time to replace fossil energy as a source of electricity generation. The use of environmentally friendly renewable energy continues to be developed in order to deal with the energy crisis and create a healthy environment. The purpose of writing this final project is to analyze the electrical power resulting from the conversion of cow dung in a biogas power plant, so as to produce the efficiency value of biogas as a power plant. In this final project, electric power is generated from biogas and LPG gas which are converted using a generator set, after which the comparative values of biogas and LPG gas are obtained. The location of this research was conducted at a cattle farm in Girinata Village, Dukuntang District, Cirebon Regency. Calculations are made using varying loads, LPG gas fuel produces electricity that is quite stable compared to biogas which is still unstable. The stability of the electric power is generated due to the presence of high and stable fuel pressure, the more stable the pressure, the stable the generated electric power.
