Abstract

The design of the User Interface and User Experience is very influential for user comfort, so accurate analysis is needed according to user needs. The Katia Derma Clinic is a clinic that is devoted to the treatment of facial skin health care and releases skincare products which are currently planning to create a mobile-based application. With the planning of making the application, the user interface and user experience will be designed first using the Design Thinking method. Testing the results of the design in this study was carried out using the User Experience Questionnaire (UEQ) testing method. Based on the test method used to test the design results in this study, positive results were obtained for all scales, namely the Attractiveness scale with a mean value of 2.028, Efficiency with a mean value of 2.075 and Dependability with a mean value of 1.725 included in the Excellent category, while the Perspicuity scale with a mean value of 1.825, Stimulation with a mean value of 1.525 and Novelty with a mean value of 1.225 are included in the Good category.

Abstract

Jambu biji merupakan komoditas tanaman di Jawa Barat dengan jumlah produksi tahun 2021 mencapai 692.488 kuintal. Produksi ini mengalami penurunan sebesar -12,82% dibandingkan dengan tahun 2020 yang sebesar 794.345 kuintal. Penelitian menggunakan teknologi deep learning dengan algoritma Convolutional Neural Network (CNN) dan berarsitektur MobileNetV2 untuk melakukan klasifikasi citra digital daun dan buah jambu biji yang telah diberi label atau disebut supervised learning. Metode pengembangan yang digunakan dalam penelitian ini adalah Cross Industry Standard Process for Data Mining (CRISP-DM). Berdasarkan hasil penelitian ini, model daun jambu biji memiliki hasil evaluasi yang sangat baik, training accuracy sebesar 99,6%, validation accuracy 100%, training loss 3,2%, dan validation loss 3,1%. Confusion matrix model ini memiliki akurasi 100% dari 63 data validasi. Sementara itu, model buah jambu biji memerlukan dropout sebesar 0,2 dan kernel regularizers L2 sebesar 0,01 untuk mengurangi overfitting. Model ini memiliki training accuracy sebesar 98,8%, validation accuracy 91,6%, training loss 19,1%, dan validation loss 38,6%. Hasil confusion matrix menunjukkan akurasi model ini mencapai 91,6% dari 84 data validasi. Kemudian model berhasil diimplementasikan menjadi aplikasi berbasis mobile menggunakan bahasa pemrograman Kotlin.

Abstract

Kansei Engineering is a method for realizing certain product designs based on a systematic exploration of human feelings and sensations (sight, touch, smell, hearing, taste). In mobile applications, the most important factor apart from the technical aspects of the system is the design. Design is an important factor in a mobile application because it becomes a liaison between the user and the existing system. The Mobile Learning application is not only enough to run the application and there are no errors, but the application must be built according to the wishes and interests of the user, this study aims to determine the emotional factors of the user, apply Kansei Engineering in designing and make recommendations for application display design according to Kansei Engineering. This methodology refers to Kansei Engineering Type I. This study uses Kansei Word to detect the user's feelings when looking at the specimen design. The list of Kansei Words used is 10 words related to the Majelis Daur Ulang mobile learning application. There are 5 specimens of similar Mobile Learning applications used. This study involved 32 participants, using multivariate statistical analysis, namely Cronbach's Alpha (CA), Correlation Coefficient Analysis (CCA), Principal Component Analysis (PCA), Factor Analysis (FA) and Partial Least Square (PLS). This research resulted in 2 recommendations for the design Majelis Daur Ulang Mobile Learning display, namely "Professional" and "Unique”.
