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

The community service activities in Kaduela Village, which were part of a matching fund program for the year 2023, were executed from July–December 2023 in accordance with the proposed activity plan. The objective of this initiative was to establish a comprehensive water pipeline infrastructure to provide clean water to the inhabitants of Bina Loka and Bina Bakti Hamlet, who lacked access to the numerous springs located in Kaduela Village. Proper and comprehensive piping planning was necessary to provide equitable distribution of water among community members in the two elevated hamlets relative to the water source. The process of addressing issues in Kaduela Village involved several sequential steps. These steps encompassed the collection of primary and secondary data, the depiction of the new piping network on a map of Kaduela Village, the simulation of the new piping network using Epanet software, the construction of the new piping network, and the subsequent commissioning of the system. The chosen pipe network configuration is a dead-end system, which was deemed appropriate for implementation in the Bina Loka and Bina Bakti hamlets, with the aim of providing water services to a total of 58 households in Bina Loka and 15 households in Bina Bakti. The process of pipeline network designing was conducted by Mechanical Engineering students from Universitas Pasundan and Universitas 17 Agustus 1945 Cirebon, under the supervision of their respective supervisors, utilizing the Epanet software. In addition to receiving funding under the 2023 matching fund program, this initiative also garnered comprehensive support from the BUMDES Arya Kamuning as the primary collaborator

Abstract

Temperature is important parameter in many technological and scientific applications. Accurate temperature measurement is needed to monitor and control various processes, including in industry, agriculture, and in other system settings. There are several temperature sensors that can be used in measuring and monitoring microcontroller-based temperatures, for example DS18B20, DHT11, DHT22, LM35, SHT40, each of these sensors has advantages and disadvantages. In this study, we will discuss testing of two types of sensors, namely DHT11 and DS18B20. The performance of the two sensors will be tested, value of accuracy and the level of error in reading compared to tools commonly used in measuring temperature in the server room. The method used in this study is an experimental approach to compare the performance of the DHT11 and DS18B20 temperature sensors. The experimental approach allows us to perform tests and measurements directly on both sensors to obtain objective and accurate data. From the results of testing the temperature in the server room using the DHT11, DS18B20 sensors and compared with the Fluke 179 True-RMS Digital Multimeter, 10 trials were carried out, showing an average error value of 3.37 for the DHT11 sensor and 1.17 for the DS18B20 sensor. for the accuracy value of 96.63% for the DHT11 sensor and 98.83 for the DS18B20 sensor.

Abstract

Microhydro power plants are small-scale power plants that use hydropower as their driving force. The hydropower used can be in the form of water flows such as irrigation canals, rivers or natural waterfalls. Microhydro power plants principally utilize the height and amount of water flow discharge per second on the water flow of irrigation canals, rivers or waterfalls. This flow of water rotates the turbine shaft so as to produce mechanical energy. One of the components in microhydro power plants is a turbine. The type of turbine used in low-head water flow is a screw turbine. This study discusses the effect of blade distance on the performance of microhydro power plants. The change in blade spacing given is 15 cm, 20 cm and 22 cm spacing with a 40-degree blade slope. From changes in blade spacing greatly affect the power and efficiency of the turbine. The highest power is generated by the use of 15 cm blades of 1267 watts. The efficiency of the turbine is also affected by the power generated by the turbine itself. The highest turbine efficiency is produced by the use of a blade distance of 15 cm of 37.25%, the closer the distance between the blades the greater the power and efficiency generated in the turbine itself.

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

A door security system utilizing face recognition technology based on TensorFlow Lite has been developed to enhance access security and convenience. This research aims to design a system capable of accurately recognizing faces in real time, integrating it with door lock devices, and ensuring user data security. Employing the waterfall method, the system was implemented using an ESP32-CAM microcontroller and deep learning algorithms. Testing results demonstrated a face recognition accuracy of 91% in identifying and processing commands from 200 trials with ten facial variations. Successful integration with door lock devices was achieved through serial communication. The system also features activity log recording for monitoring purposes. This solution offers greater practicality and security than RFID systems as it eliminates the need for physical cards. This research contributes to developing more sophisticated and user-friendly home security systems, with the potential for further enhancements in recognition capabilities under various lighting conditions and integration with other biometric technologies
