Abstract

Orange are very popular and consumed by most Indonesians. Oranges are the fruit with the second largest productivity in Indonesia. North Sumatra province is one of the areas with the highest number of citrus harvests. Buyers of oranges in North Sumatra generally taste oranges before buying because taste is the most important attribute according to consumer perceptions. After tasting the rsa citrus fruit and the taste is sweet, the buyer will immediately buy the orange juice. During the wrapping process, sometimes the seller will mix fruit with lower quality and unsweetened taste. So from these problems this research focuses on making a system that can classify the taste of citrus fruit. The classification process is carried out using the naive Bayes method. The classification process requires training data with three parameters, namely color, weight and diameter. Color data obtained with the TCS230 sensor, weight data using the load cell sensor and diameter data using the ultrasonic sensor. After the data is obtained, the classification process will be carried out. After the classification process is complete, the hasl will be displayed on the LCD. The naive Bayes classification was tested with 15 test data and produced an accuracy of 80%.

Abstract

Monitoring system is common this time. However, security system needs attention. Because if unauthorized people controls the data from monitoring system, it can endanger owner of monitoring system. Aspect that need to guarded in monitoring system is confidentiality. SPECK algorithm can fulfill confidentiality security and has advantage of low specifications system. SPECK algorithm is implemented in monitoring system on manager and agent when sending and receiving data. Tests includes test vectors, performance, sniffing attacks and known plaintext attacks. Time for monitoring system process encryption has an average 1,780.738 ms on Raspberry Pi 0 W, 799.173 ms on Raspberry Pi 2 and 481.7921 ms on Raspberry Pi 3. Time to process decryption has an average 2,007.717 ms on Raspberry Pi 0 W, 880.4057 ms on Raspberry Pi 2 and 508.9488 ms on Raspberry Pi 3. Data amount before and after encryption is 524 byte in resource, network and disk scenarios. Results of test vector test is same as the SPECK paper so they declared successful. Sniffing test also successful because when checked using Wireshark application, contents of the packet is ciphertext. In known plaintext attack test, the test was successful because the resulting ciphertext failed to decrypt by brute force.

Abstract

In modern era, music has become an integral part towards many people, especially to accompany their daily activities. Further technological advancements such as the internet has affected and made easier the distribution of music for music affocionados. However for some, too many music in the distribution resulted in them having some difficulty in finding the one that suits their preference. Therefore, there exist a need for a system where music are grouped to small groups based on specific criteria-such as genre-and then recommending those to the user to ease their search. In realizing such system, the researcher conducts a research to develop a genre-based music categorization system. This recommendation system is developed as a mobile-based application in the Android operating system, where music that are recommended is based from surveys from scholars as well as using forward chaining algorythm. The system will recommend music within a databse in the form of playlist that is further segmented into the time of the day. Blackbox testing of the system is done with the intention to test the accuracy percentage of system's primary function. System Usability Scale test done to the system is also to measure the usability of said system, taken from testing the system to users directly.

Abstract

The motorbike rental business is a promising business for now, especially in Indonesia. One of the businessmen in this field is Arfand Motorent. However, in practice many repetitive processes are carried out between the admin and the tenant, and the use of a platform that is not integrated and the presence of manual forms causes human errors, data duplication which results in data integrity and validity being difficult to maintain, resulting in increased costs and resources so as to solve the problem. The motorbike rental management application based on Progressive Web Apps or abbreviated as PWA is built. PWAs have a wider range, can be accessed on a variety of devices easily, require less effort to access them without the need to perform an installation, and are smaller in size than native applications. The needs analysis stage obtained 68 functional requirements and 2 non-functional requirements. The design stage results in designing systems, components, databases, and interfaces. The above steps are used as a reference in the implementation stage which produces program code with the front end library, react js and the framework for the backend using laravel. The functional testing phase includes unit testing, integration, and validation. As well as non-functional testing by testing performance, reliability, and compatibility. Both functional and non-functional tests are valid.
