Abstract

The fan is a tool that is needed to rotate air circulation. In the market, fans are usually controlled manually by turning the control switch. The research problem is how to make a fan tool that can automatically turn on when there is a change in temperature. The purpose of this research is to facilitate users in using the fan. The method used is Research and Development. The stages of Research and Development include: data collection, design, and testing. The automatic fan control circuit consists of an atmega8 microcontroller integrated with a temperature sensor, button and relay. The circuit can display the temperature and can control the fan. The automatic fan control circuit is made on a PCB whose PCB layout is made using a computer with the PCB manufacturing process still using screen printing techniques. The conclusion is that the manufacture of automatic fan control devices integrated with temperature sensors, buttons and relays can facilitate the control of fans so that users do not need to control when the temperature changes.

Abstract

Website merupakan salah satu media informasi dan komunikasi yang membutuhkan internet untuk menjalankannya. Pembuatan password masih kurang menyadari akan keamanan pengguna. Hal ini memancing para penjahat siber untuk melakukan serangan untuk mengambil password login milik pengguna. Salah satu serangan yang mungkin dilakukan adalah serangan brute force dengan cara bereksperimen dengan semua kemungkinan password yang ada. Penelitian ini bertujuan untuk membahas teknik serangan brute force dan cara pencegahannya agar pengguna dapat lebih berhati-hati dalam membuat password dan lebih waspada terhadap keamanan password yang dimiliki. Penelitian ini menunjukkan bahwa metode brute force dapat bekerja dengan sempurna jika tidak ada Captcha pada login web, membatasi login yang tidak memblokir akun dalam waktu yang lama, dan tidak menggunakan Two Factor Authentication

Abstract

The PeduliLindungi app has supported the government in controlling the spread of COVID-19. The purpose of this research is to explore new user needs and create design prototypes for the latest features of the PeduliLindungi application. Design thinking is used to know empathizing, define, ideate, and prototype. Figma Tools was chosen to develop a prototype that visualizes the latest features of the PeduliLindungi application. The results of this research are information about pain points from application users, problem statements, problem solving ideas, and user interface features for the new PeduliLindungi application. Based on the results of user pain points, the features developed are covid-19 event advertisements, Online Registration, Night Mode, Covid-19 educational videos, Tourist Visits, and Vaccine History. Based on the evaluation results using the Single Easy Question (SEQ), it is found that advertising, registration, night mode, and vaccine history are worth 7, meaning that the level of use is basic to use. Tourist visits and educational videos are worth 5.75, which means that improvements need to be made by taking into account notes from respondents during the testing process.

Abstract

To expand the coverage of current aviation VHF communication services, it is necessary to develop a satellite-based VHF communication system. This research aims to analyze the satellite link budget calculations for VHF AMS(R)S frequencies using a Low Earth Orbit (LEO) satellite at an altitude of 600 km, in accordance with the studies conducted by ICAO and ITU. The link budget calculation, using parameters such as aircraft antenna gain = -1 dBi, satellite antenna gain = 8 dBi, RF power of the aircraft = 16 watts, and RF power of the satellite = 85 watts, results in satellite receiver sensitivity between -107 dBm - 25.56 dB, as well as aircraft receiver sensitivity between -93 dBm - 38.65 dB. When simulating an end-to-end link budget (loopback: aircraft-satellite-aircraft between 14.92 dB - 14 dB. Simulations were also carried out for voice communication using an AWGN channel illustration with an Eb/No of 10 dB, resulting in the performance of the VHF audio link.

Abstract

The government officially stopped broadcasting analog television or what is known as Analog Switch Off (ASO) on November 2, 2022, in Jabodetabek. It impacts analog TV users in Jabodetabek, who can no longer receive television broadcasts on their analog televisions. This research aimed to determine user acceptance of digital television broadcasts after implementing ASO in the Jabodetabek area. In the present study, the experience of digital TV users is evaluated using the UTAUT (Unified Theory of Acceptance and Use of Technology) 2 model and the Structural Equation Model (SEM). The data was obtained from a questionnaire distributed through digital media for the Jabodetabek area. According to data processing, the two factors that significantly influence the user experience of digital television broadcasts are the Analog Switch Off (ASO) policy factor and the habit factor. The hypothesized model suitability test fits the resulting data and can affect the Behavioral Intention 41.4.

Abstract

Hydroponic system is a technique of cultivating plants without using soil as a growing medium, but using water that is given nutrients and oxygen as a growing medium. Cultivation with hydroponic techniques must be able to pay attention and control nutrients, water content, and water ph. This research aims to create a lettuce cultivation system with intelligent hydroponic techniques using the ATmega2560 microcontroller. This system uses Arduino Mega as the control center, TDS sensor to monitor nutrition, PH sensor to monitor water acidity, and ultrasonic sensor to monitor water level. The optimal growth characteristic of lettuce is that the acidity level must be at pH 5.5-6.5 with the nutrients provided at 685-950 ppm. This system can help lettuce cultivation with hydroponic techniques by monitoring and controlling nutrients, pH, and water content in cultivated plants in real time to optimize lettuce growth.

Abstract

Pengeringan menggunakan oven dilakukan untuk supaya lada lebih bersih dari kotoran serta efisien terhadap waktu terhadap pengeringan lada, Proses pengeringan dari biji lada ini masih dilakukan dengan mengandalkan sinar matahari, dimana jika kondisi cuaca hujan akan sangat memperlambat pengeringan. Untuk itu dibutuhkan oven sebagai alat untuk pengering biji lada, agar tidak terlalu bergantung dengan kondisi cuaca. Sistem pemanas oven ini menggunakan gas LPG, hygrometer yang digunakan untuk mengukur suhu serta kelembaban dan thermostat untuk mengatur suhu ruangan didalam oven, juga di lengkapi dengan pemantik api otomatis supaya mempermudah dalam menghidupkan api didalam oven. Pengeringan lada yang telah diuji mulai dari 50?C, 60?C, 70?C, 80°C dan 90?C semua kering dengan waktu terlama 99 menit dan waktu tercepat 15 menit.

Abstract

This study aims to analyze changes in valve clearance on engine power and torque. The subjects in this study were four-stroke motorcycles with a cylinder capacity of 100 cc. The stages of the research included: 1) Preparation by adjusting the size of the inlet and outlet valve gaps with the dimensions in millimeters being 0.03, 0.05, and 0.07; 2) Testing using a dyno test; 3) The conclusion is based on the results of the dyno test tool print out data. Research results: 1) The maximum engine power achieved at the valve clearance size of 0.03 mm and 0.05 mm is 4.5 hp. Maximum engine power at 0.03 mm valve clearance is achieved at 6.42 rpm, while 0.05 mm valve clearance is achieved at 6.39 rpm; 2) The highest maximum engine torque among the three variations in valve clearance size, is 0.03 mm, which is 5.92 N.m at 3.081 rpm; 3) The size of the valve gap that is not by the standard specifications will significantly affect the power and torque of the engine.
