Abstract

The use of passwords has been used in many ways such as logging into a website application. However, most of these passwords still use static passwords, making them vulnerable to tapping login passwords. There are many ways that hackers can do to hack into websites that use a login system, such as phishing techniques. Layered security is required to secure the login system, the use of the OTP code is one way of verification and can only be accessed by the user himself so that it can reduce the potential for wiretapping of access rights. The application of QR Code technology is quite practical and provides an easy solution to enter the system. Users don't need to log in by entering their username and password repeatedly, just pointing the QR Code at the webcam to be scanned. To increase login security to prevent intrusion into the system, authentication is made in the form of a unique, single-use code called One Time Password (OTP). The password that previously used one username and one password will be added to another random password which will be sent to the user's cellular phone via SMS message. This research is able to provide convenience when accessing a QR Code login and increasing security in the system because the OTP code that is sent is only valid for one login session and is valid for only 5 minutes, so the OTP code cannot be reused in the next login session.

Abstract

Gold is a type of precious metal that has economic value and is also profitable because it can be used as an investment tool. Another advantage of investing in gold is that gold has properties that are resistant to inflation. The problem in this study is that the price of gold can fluctuate from day to day so gold is needed to forecast a relatively accurate gold price so that investors are able to get a profit according to the plans that have been made. The use of deep learning techniques makes it very possible to carry out learning using more complex layers in order to receive high accuracy for forecasting gold prices. The research method used in completing this final project is to use the waterfalld method where each work will be carried out sequentially from top to bottom. Forecasting gold prices is useful for the community, because it makes it easier for people to see the price of gold market value in the next few months. In this study, we will use the GRU (Gated Recurrent Unit) algorithm in forecasting the gold price and then use the error rate measurement technique, namely MSE (Mean Square Error) which serves to check the estimated error value in gold price forecasting. What will happen in this research is a system that can predict gold prices every day based on gold price input data. This study uses the Python programming language and uses the GRU (Gated Recurrent Unit) algorithm.

Abstract

The Raskin program is a program from the government to reduce the burden of spending on the Indonesian people. With existing technological facilities, distribution problems for the Raskin program can be reduced. Rice distribution is an activity that is often carried out around the community. However, rice distribution often takes a very long time and causes long and inefficient queues. To overcome this, an Arduino-based Rice ATM was created to facilitate the distribution of rice using an Arduino microcontroller, photoelectric sensor, loadcell, Rfid, and rice distribution servo motor. can identify objects that have been marked with a unique identifier code. Based on this, this study discusses the rice ATM system using an Arduino-based e-ID card. The results of the testing and implementation of this system are that when the RFID card is tapped, then the ID and balance are checked on the oled lcd, if appropriate, the servo motor will open and remove the rice and if the RFID tag used is not appropriate and the balance provided has run out, the servo motor will not work. open. Distance and position of RFID reading after 1 test. Picking up rice at this ATM is only done 1 time 1 day in 1 card, if you want to take more than 1 time the e-KTP must be reset, the quantity issued by this rice atm system is 1 kg. From these problems, an ATM Rice tool was produced using a weight sensor or loadcell. From the results of testing this tool works well and is able to overcome the problems that have been experienced by the community
