Judul: Tingkat Sanitasi Tangan Food Handler di Warung Makanan Sekitar Kampus Institut Pertanian Bogor Dramaga
Abstrak: This research was conducted in order to describe the sanitary condition of food kiosks around IPB Dramaga through amount of Staphylococcus aureus on food handler’s hands. Total of 42 food kiosks around IPB Dramaga were selected randomly as the respondents. The research was conducted with cross sectional study. Data was collected by interviewing the respondents using the questionnaires and examining total of Staphylococcus aureus from hands using replicate organism direct agar contact (RODAC). Data was analyzed descriptively. The results showed that the majority of respondents were adult and elder (73.8%), had low educational level (57.1%) and selling experience under 10 years (69.1%), never attended the training about food safety (71.4%), and never found out the health department supervision (71.4%). Based on RODAC analysis showed that 59.5% of food handler’s were contaminated by Staphylococcus aureus belong to high contamination. Thus it was concluded that the sanitation of food kiosks and personal hygiene were still low.

Abstrak: The aim of this study was to assess of hand sanitation of food handlers and identify risk factors on hygiene practices. Total of 42 food kiosks around the Bogor Agricultural University campus in Dramaga Bogor were selected randomly as unit samples and one of food handlers in each kiosks was selected as a respondent. The research was conducted with using questionnaires and counting of microorganism number with RODAC method. The result showed that most of food handlers were in the age range of adults and old (73.8%). More than half of respondents had attended school until senior high school (57.1%), new experience of trading (69.1%), no attended trainings (71.4%), and no subjected to inspections (71.4%). Generally the food handlers had good knowledge, moderate attitude, and good practices. There was a significant correlation (r=0.752; p<0.05) between knowledge and practices. Only few of food handlers (16.6%) were categorized in acceptable criteria of total plate counts of hand surfaces. The identified risk factors on hygiene level were young age (OR=9.80), adult age (OR=8.40), and low level education (OR=12.14). This condition could be a potential risk for consumer health.

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
