Abstract

Innovation is a process to generate new ideas and change something of value in meeting user needs. Innovation requires measuring the readiness level of innovation in universities to monitor and carry out the resulting innovations. This research was conducted to design an application for measuring the level of innovation using the User Experience Lifecycle (UXL) method. This application can assist in submitting activities and measuring the level of innovation carried out by lecturers or students. This application is made in four stages, namely, analysis, design, prototype, and evaluation. Analysis of user needs is carried out at the Innovation Unit of the Institut Teknologi Telkom Purwokerto through interviews. The interaction design requirements are generated in the form of design requirements and work activity affinity diagrams with two main tasks, namely proposing innovation measurements and obtaining progress reports. After that, a discussion was held in the form of a design thinking and ideation session with the innovation unit that produces personas, sketches, and scenarios. Furthermore, the design implementation is done by creating a medium-fidelity prototype, and the results are tested using the System Usability Scale (SUS). Of the ten questions that must be answered distributed to lecturers and students, the results of the test by the lecturer got a value of 69.17 or B (Good), and students rated 69.40 or B (Good). Based on these results, the application's medium-fidelity prototype has exceeded the minimum requirements of 67 or C (Enough) so that the prototype can be produced so that it can be delivered to the public or the public.

Abstract

Hipertensi adalah kondisi ketika tekanan darah pada pembuluh darah bersih meningkat secara kronik. Jika tidak segera ditangani dapat menyebabkan peningkatan resiko kejadian penyakit lainnya, misalnya kardiovaskuler, serebrovaskuler dan renovaskuler. Diagnosis penyakit hipertensi perlu ditegakkan sedini mungkin guna menurunkan peningkatan resiko kejadian penyakit lainnya. Penelitian ini bertujuan menghasilkan sistem yang mengimplementasikan metode Case-Based Reasoning yang dapat membantu paramedis untuk mendiagnosis penyakit hipertensi. Implementasi sistem dirancang menggunakan bahasa pemrograman PHP serta penyimpanan data kasus menggunakan MySQL. Kasus-kasus penyakit hipertensi yang sudah berhasil ditangani oleh dokter dijadikan sebagai data acuan untuk mendiagnosis kasus hipertensi yang baru. Kasus baru yang berisi faktor resiko, gejala dan riwayat penyakit selanjutnya dicari kemiripannya dengan kasus-kasus lama dengan cara menghitung nilai similaritas menggunakan Minkowski Distance. Pengujian dilakukan pada 172 data menggunakan 10-fold Cross-Validation. Hasil perhitungan dengan menetapkan threshold sebesar 0,90 didapatkan tingkat akurasi sebesar 94,71%. Hasil penelitian menunjukkan implementasi Case-Based Reasoning dapat digunakan untuk melakukan diagnosis penyakit hipertensi

Abstract

This study investigates the sound of Hanacaraka in Javanese to select the best frame feature in checking the reading sound. Selection of the right frame feature is needed in speech recognition because certain frames have accuracy at their dominant weight, so it is necessary to match frames with the best accuracy. Common and widely used feature extraction models include the Mel Frequency Cepstral Coefficient (MFCC). The MFCC method has an accuracy of 50% to 60%. This research uses MFCC and the selection of Dominant Weight features for the Javanese language script sound Hanacaraka which produces a frame and cepstral coefficient as feature extraction. The use of the cepstral coefficient ranges from 0 to 23 or as many as 24 cepstral coefficients. In comparison, the captured frame consists of 0 to 10 frames or consists of eleven frames. A sound sampling of 300 recorded voice sampling was tested on 300 voice recordings of both male and female voice recordings. The frequency used is 44,100 kHz 16-bit stereo. The accuracy results show that the MFCC method with the ninth frame selection has a higher accuracy rate of 86% than other frames.
