Abstract

Rice is one of the foods that contain enough nutrients and boosters for the human body, because it contains ingredients that are easily converted into energy. In Indonesia there are more than 1000 types of rice varieties, and every year new varieties appear. Farmers find it difficult to determine which type of rice they will plant. Farmers must try each type of different varieties each season, to find out which quality rice. For this reason, a decision support system is needed to select qualified rice. In the decision support system two methods of comparison are used, namely the Simple Additive Weighting (SAW) method and PROMETHEE. The Simple Additive Weighting (SAW) method will be compared to the PROMETHEE method. In a decision support system, the data used will be changed first into the form of weights that have been determined based on parameters. The types of rice used are paddy and hybrid rice. Both methods will be compared based on the length of time of execution and the success rate of selecting rice quality. The end result of the system for rice using both methods is the angke for lowland rice and the 6 ceva hipa for hybrid rice. with an execution time of 570,0008 milliseconds for the SAW method, and PROMETHEE method with an execution time of 12488.2 milliseconds in lowland rice, and 1140,006 milliseconds for the duration of SAW execution, 16400,029 for the duration of PROMETHEE for hybrid rice. The SAW method is faster than the promethee method.

Abstract

Whatsapp is a cross-platform messaging application that allows us to exchange messages without SMS fees, because WhatsApp uses the same internet data package for email, web browsing, and more. The WhatsApp application reportedly has improved the security system of applications that are end to end encryption (E2EE). This proves that the WhatsApp manager paid considerable attention to privacy and security issues for its users. In addition, it also implies an important matter where business actors have begun to realize that the application of cryptographic services is part of a very promising business strategy or even determines the present and future consequences. The consequence of implementing E2EE is the description encryption process that takes place at the application layer (OSI layer). Cryptography is a study that studies methods to send messages in secret (that is, encrypted or disguised) so that only the intended recipient of the message can decode and read the message. For this reason, cirptography is one method that can implement E2EE on whatsapp. One Time Pad (OTP) is a type of symmetry algorithm, each key is only used for one message. If the key is random (cannot be reproduced) and only used once, then the algorithm is perfectly safe. The MAC (Message Authentication Code) is an identifier to prove the authenticity of a document obtained by using meaningless messages obtained from processing some of the contents of the document using a private key.

Abstract

Tiongkok is a country with a large population and is in several states. In addition, Tiongkok has a variety of languages. Hokkien is the worldwide language of China and is widely known to many people. This is evidenced by the many China Town markets. In Indonesia there has been a lot of Hokkien language guidance. In almost every elementary school in the city, adding Hokkien language lessons is a must for elementary school students. Even starting from the playgroup has also been taught Hokkien. But still there are children who do not understand because of the different ways of writing by reading Hokkien. In this research, the writer makes an android-based hokkien language learning media which can be utilized by users with mobile technology, designed learning media adapted to the curriculum in elementary schools with 5 subject matter. From the results of testing designed learning media can help make it easier for students to better understand hokkien language.

Abstract

PT. PLN (Persero) has been getting prepaid and postpaid electricity program services, but in postpaid electricity programs, human errors often occur when officers read the kwh meter and PLN officials do not go down to residents' homes to record consumer usage due to the co-19 pandemic. In this research, an electrical energy monitoring tool was built using SMS (short massage service) based on the ATMEGA 2560 microcontroller that can measure and monitor the electrical energy consumption in real time using a voltage sensor and current sensor SCT013-030. The results of the current and voltage sensor readings will be forwarded to the ATMEGA 2560 microcontroller to be converted to the amount of electrical energy consumption and the amount of payment in accordance with the rates set by the PLN.
