Behind the success of the Free Nutritious Meal Program (MBG), there are several problems related to the health factors of the program targets, namely, there are several cases of allergies that occur in schools, inadequate understanding of allergen management owned by food processing vendors, and the high cost of laboratory tests and the process that takes a long time. So, to overcome these problems, an application is proposed that can help detect allergens in food products using data mining and machine learning approaches. SVM and AdaBoost algorithms each have advantages that can be used to help build an optimal allergen detection model. This research uses a cross-validation model validation method with a value of K = 10 to help improve the performance of the model built. In this study, from the entire fold, an average accuracy value of 98.74% was obtained. To evaluate the model built, this research has also conducted several new data inputs, and in each new data input, the accuracy value is obtained above 99%. This indicates that the model built, namely the combination of SVM and AdaBoost algorithms with the cross-validation model validation method, produces high accuracy, so this model can greatly assist the allergen detection process in food products.

Salah satu algoritma yang sering digunakan untuk melakukan deteksi pada wajah yaitu Viola-Jones. Metode ini merupakan gabungan dari 3 buah fitur yaitu integral image, adaboost dan cascade classifier. Masing-masing fitur mempunyai fungsi tersendiri dan saling melengkapi. Integral image digunakan dalam penentuan ada dan tidaknya gambar, adaboost untuk memilih dan mengatur nilai threshold, sedangkan cascade classifier untuk mengklasifikasi daerah yang akan di deteksi. Untuk memudahkan deteksi, terurtama pada bagian mata maka digunakan Haar like feature. Proses pengenalan wajah telah dilakukan pada gambar dengan satu objek dan beberapa objek. Hasil impelemntasi juga dapat mengenali objek foto lukisan dan foto tampak samping. Dari seluruh percobaan di dapatkan nilai rata-rata sebesar 65% dengan sebaran nilai akurasi tertinggi 70%, sensitivitas 55% dan spesifitas 71%.
