Abstract

Pengembangan perangkat lunak berorientasi objek membutuhkan pendekatan yang berbeda dengan pengembangan perangkat lunak terstruktur. Perbedaan tersebut terdapat pada tahap desain, implementasi, dan evaluasi kualitas perangkat lunak tersebut. Dengan demikian, dibutuhkan metrics yang berbeda dengan traditional metrics untuk melakukan evaluasi kualitas perangkat lunak tersebut. Dalam penelitian ini akan diajukan enam buah object oriented matrics. Keenam metrics tersebut memiliki sudut pandang yang terkait dengan faktor-faktor kualitas perangkat lunak. Dengan demikian, metrics tersebut dapat digunakan untuk melakukan evaluasi kualitas perangkat lunak berorientasi objek dari beberapa faktor kualitas yang terkait., sehingga dapat menjadi rekomendasi bagi pengguna proyek peranhkat lunak dan pembaca dalam melakukan penelitian tentang evaluasi kualitas perangkat lunak berorientasi object maupun penggunaan matrics yang dikembangkan.

Abstract

Cake merupakan panganan yang terbuat dari campuran bahan-bahan seperti tepung, gula, telur, garam, susu, aroma dan lemak yang dikembangkan dengan atau tanpa bahan pengembang. Penentuan tingkat kematangan cake dasar putih dilakukan berdasarkan grade warna permukaan pada saat proses pemanggangan. Namun hal ini sering menjadi kendala karena faktor persepsi komposisi warna setiap orang berbeda-beda. Pengambilan data citra menggunakan kamera 3.2 mp dan 13 mp, setelah itu citra disegmentasi dengan color filtering untuk membuang pixels yang mengandung efek lighting. Tahap selanjutnya yaitu ekstraksi ciri warna RGB kemudian dilakukan pelatihan dengan metode Learning Vector Quantization (LVQ). Hasilnya aplikasi mampu menentukan tingkat kematangan kue cake dasar putih dengan rata-rata akurasi 65,19% dan cake dasar cokelat sebagai kelas validasi 96,88% untuk kamera 3.2 mp sementara pada kamera 13 mp rata-rata akurasi 64,93% dan cake dasar cokelat sebagai kelas validasi yaitu 93,75%. Keberhasilan identifikasi dipengaruhi oleh faktor pencahayaan dalam ruangan, jarak pengambilan dan wadah penampung.

Abstract

Recipients of housing assistance for poor people are government assistance programs that have a limited budget so that not all people receive housing assistance. Criteria for recipients of housing assistance can be seen from 13 criteria such as age, education, occupations, income, land ownership, home ownership, number of occupants, roof conditions, wall conditions, floor conditions, ownership of bathrooms, water sources, electricity sources. To get a decent recipient, a Decision Support System (DSS) is needed to make it easier for the government to provide housing assistance for poor people. Fuzzy Method Simple Additive Weighting (F-SAW) is one method in DSS that can help resolve unstructured problems and can accommodate weakness of SAW method in linguistic and numerical assessments. System testing conducted use sensitivity testing that is with change value weight each criteria in a manner gradually. From sensitivity test above that has been done, the most sensitive is education criteria because when tested three times of high weight is changed to very high has experienced one change, low has 4 times changed and very low has 4 times the change, with these changes the results got 90% presentation for education criteria. From the results of comparisons that have been made between Dinas Sosial and system, data quota that deserves to receive housing assistance as much as 30 data from dinas sosial showed that total data quota is 20 which is same with system and 10 data is not same with system.
