Abstract

Information technology is an activity of collecting, processing, managing, storing, disseminating and utilizing information. Apart from involving hardware and software, this technology also pays attention to human interests in its utilization. Car Showroom is a company engaged in buying and selling used cars. As a growing company and from its stagnant sales chart data for the last 5 years, Car Showroom took the initiative to make the internet a marketing medium. Judging from the reality, so far it has been difficult to provide information regarding the product. Making it easier to design a system that is created, as well as implementing a used car sales application in a car showroom made using the PHP programming language with the MySql database so that the information held by the showroom can be accessed by users online and in real time. With this application, it can help users find used cars online. Based on the results of the recapitulation of the 7 testing criteria that have been carried out, the results show that the number of answers from respondents has a value of 100% in accordance with testing system functionality using blackbox testing.

Abstract

The election of the class president is one of the activities that is often carried out when students are in school. A class in school can be interpreted as a country that has a government system. So, it is very important for a class to have a leader. Usually the election of the chairman is done by voting from class members. Later as a chairman, you will have various obligations. Simple Additive Weighting (SAW) is a method that is often known as the weighted sum method. Based on the needs gathering, an approach is proposed using a decision support system using the SAW method in selecting class leaders. There are 4 criteria used in selecting class leaders. The purpose of the weighted sum is to find the weighted sum of the ratings in each alternative on all criteria. Based on the calculation results using SAW for the election of the class leader, the 1st rank of the class leader election is Ahmad Jatmiko with a score of 0.99. Ranked 2nd in the class leader election was Muhammad Akbar with a score of 0.9. And ranked 3rd in the class leader election is Siti Setianingsih with a score of 0.8525.

Abstract

This study aims to solve the problem of determining scholarship recipients through a decision support system with output in the form of ranking using the Combined Compromise Solution Method. The application of the Combined Compromise Solution (CoCoSo) method in determining scholarship recipients will result in a comparison of the scores of all students who register to receive scholarships from schools. So that through the decision support system developed it can produce prospective scholarship recipients according to predetermined criteria and the selection process does not take long because the decision support system built is equipped with a web-based application using Laravel 8 which is used to determine scholarship recipients. Calculations for determining scholarship recipients using the Combined Compromise Solution (CoCoSo) show that the results of calculating the final score of the 1st scholarship recipient received a final score of 2.7031 obtained by Dwi Adhawati, the 2nd scholarship recipient received a final score of 1.9111 obtained by Muhammad Ferdi, and the 3rd scholarship recipient with a final score of 1.8684 was obtained by Muhammad Irfan.

Abstract

Cats are the most popular mammals for many people, such as the Angora cat. Cat lovers don't look at age, most of these cats are liked by all people so it's not uncommon for cats to be found everywhere. The Angora cat has a beautiful physique with fur and a cute face. So it's not uncommon for the Angora cat to become the most preferred charmer of hearts. This hobby of keeping cats is not only seen from their stature but must be accompanied by their health. Some of the diseases that are often suffered by Angora cats include Feline Calicivirus, Helminthiasus, Dermatopytosis, Conjunctivitis, and Toxoplasmosis. This expert system is used by carers to diagnose early disease in Angora cats based on the symptoms experienced by cats and to help provide information about the cat's disease. Research data using laboratory tests, interviews and documentation were then processed using the Fuzzy Mamdani method and research design with UML which was designed in a use case diagram model to describe system activity. The stages are forming the Fuzzy Mamdani set, determining the rules, and defuzzification. The test results with 46 symptoms from 5 types of disease with an accuracy value of this system is 90.90%. The result of this research is that the system can help Anggora lovers from an early age to find out what are the symptoms of various types of cat diseases, as well as solutions to overcome them and can consult a doctor before proceeding to a more advanced stage.

Abstract

Dalam pencatatan penerimaan setoran PT Trans Bandar Lampung masih menggunakan manual dengan menghitung satu persatu setoran dan pengisian bahan bakar mobil setiap harinya. Lalu mencocokkan pendapatan setiap bus perharinya, dari sudah berapa kali mengisi bahan bakar, berapa banyak tiket yang terjual. Seletah itu akan dikalkulasikan setiap bulannya. Hal ini membutuhkan ketelitian sehingga jika terjadi kesalahan akan merugikan pendapatan PT Trans Bandar Lampung.Upaya untuk mengatasi permasalahan tersebut, penulis menyarankan aplikasi sistem informasi akuntansi siklus pendapatan jasa berbasis desktop pada PT. Trans Bandar Lampung yang dikembangkan menggunakan bahasa pemrograman java dan mysql sebagai pengelolaan basis data dengan alat pengembangan sistem berupa UML (Unified Modelling Language) menggunakan metode Waterfall sebagai metode pengembangannya, sehingga dapat memudahkan perhitungan pendapatan jasa pada PT. Trans Bandar Lampung. Hasil dari proses perancangan ini yaitu sistem informasi akuntansi siklus pendapatan jasa pada PT. Trans Bandar Lampung dapat mengelola data supir, data pendapatan, data kas keluar (untuk kebutuhan bahan bakar dan segabinya), serta dapat mengelola laporan pendapatan dan BBM.
