Abstract

The rental system currently implemented at Mandala Outdoor Equipement requires customers who want to rent outdoor equipment to come directly or via telephone/WA communication to Mandala Outdoor Equipement. Rental of outdoor equipment sometimes causes problems, such as customers who are disappointed because they were previously confirmed to be able to rent outdoor equipment, after receiving information that they could not or that it was canceled by the provider because it turned out the stock had run out, even though this happens. After all, sometimes they prioritize renters with proximity factors because of the courage of new renters. with higher rental costs. Based on these existing problems, this research aims to build a website-based information system by applying the First in First Out (FIFO) algorithm for outdoor equipment rental at Mandala Outdoor Equipment. The method used in this research is the waterfall method. The result of this research is an outdoor equipment rental application by applying the FIFO algorithm to the web-based Mandala Outdoor Equipment so that rentals can be done via the website (anywhere and at any time) and rentals are served according to the rental time sequence (First in First Out). From the results of testing the application using a separate black box, seen from the functional aspect, both features and access rights, everything went well, successfully, and validly.

Abstract

This study aims to determine the effect of mathematical anxiety on mathematics learning outcomes. This research is quantitative research. This study's population was comprised of all 3rd-semester Informatics Engineering students, totaling 139 people across four classes. Based on the existing population, 77 students were sampled in this study, which were taken using simple random sampling. Mathematics anxiety data were obtained from questionnaires, and mathematics learning outcomes were obtained from documentation, which were then analyzed using inferential analysis with simple linear regression. This study concludes that mathematics anxiety has a negative effect on mathematics learning outcomes with a regression equation of Y=130.997-0.961X and a coefficient of determination of 0.860. This means that 86% of students' mathematics learning outcomes are influenced by mathematics anxiety. The higher the mathematics anxiety, the lower the students' mathematics learning outcomes will be, and the lower the mathematics anxiety, the higher the students' mathematics learning outcomes will be.

Abstract

Penelitian ini bertujuan untuk mengatasi masalah kesulitan pecinta kucing yang banyak terhalang kendala untuk mengunjungi seorang pakar hewan khususnya kucing dalam mendeteksi maupun mendiagnosa penyakit kucing nya dengan membangun sistem pakar diagnosa penyakit pada kucing dengan metode Certainty Factor berbasis web. Penelitian ini menggunakan metode penelitian Waterfall. Model pengembangan yang dilakukan meliputi tahap analisis kebutuhan, desain, pembuatan kode program, dan pengujian. Data diperoleh dari observasi dan wawancara yang dilakukan terhadap dokter di salah satu klinik hewan yang berlokasi di Perumnas Tj. Karang Permai yaitu Drh. Diah Purwitasari, M.sc. Pada tahap perancangan sistem, dilakukan dengan merancang flowchart, use case diagram, activity diagram, entity relationship diagram (ERD) dan perancangan desain interface. Pengujian sistem dilakukan dengan dua cara yaitu Blackbox Testing dan pengujian usability. Pengujian usability dilakukan dengan memberikan kuesioner penilaian aplikasi kepada 20 orang responden. Hasil pengujian usabilitas menunjukkan bahwa tingkat usablitas dari aplikasi adalah sebesar 93.2% dengan kategori sangat baik. Kelemahan dalam aplikasi ini adalah tidak ada pemilihan ras dan jenis kucing dalam proses diagnosa.
