Optimization of Faster R-CNN to Detect SNI Masks at Mandatory Mask Doors

In preparing for the COVID-19 endemic period, every government and private agency will be required to comply with new rules by the government, where everyone is required to wear a mask and perform physical distancing when leaving the house for activities. This is one of the new habits that will be familiarized to the public by the government in 2022 and the following year. Due to the easy transmission of the Covid-19 virus, the selection of SNI masks is highly recommended. The purpose of this study was to classify the types of SNI and non-SNI masks so that the presence of this SNI mask cluster monitoring system could increase security in locations that require the mandatory use of masks such as in schools and the masks used can function effectively to prevent the spread and transmission of Covid -19.. From the dataset, 100 pictures were taken randomly on SNI and non-SNI mask users. Where the types of masks that are SNI have been studied on Duckbil masks, KN-45, Surgical Mask 2 ply, and Surgical 3 ply are included in SNI masks and cloth masks are not included in SNI masks at a distance of 0.5 meters, 1 meter, 1.5 meters and 2 meters from the mobile device. It can be seen on the SNI mask at a distance of 0.5 meters achieving 100% accuracy, a distance of 1 meter achieving 100% accuracy, at a distance of 1.5 meters achieving an accuracy of 95% and at a distance of 2 meters achieving 90% accuracy. Whereas non-SNI masks at a distance of 0.5 meters achieve 100% accuracy, a distance of 1 meter achieves 100% accuracy, at a distance of 1.5 meters achieves an accuracy of 95% and at a distance of 2 meters achieves an accuracy of 90%

UJI TOKSISITAS AKUT EKSTRAK KUNYIT PUTIH TERHADAP KADAR GULA DARAH DAN KOLESTEROL

Kunyit putih memiliki kandungan zat utama kurkumin yang  mengandung diferuloylmethan sebagai antioksidan alami. Kurkumin memiliki manfaat sebagai antiinflamasi, antikanker, antifungal, antidiabetes dan antikolesterol. Kunyit putih banyak dibudidayakan di daerah Jawa, khususnya di Jawa Barat, Jawa Timur, terutama di hutan jati Jawa Tengah karena  obat tradisional dipercaya warga setempat mempunyai efek samping yang ringan daripada  obat modern, tetapi belum banyak penelitian mengenai toksisitas dan dosis aman dari kunyit putih. Tujuan penelitian ini untuk mengetahui dosis toksisitas akut  ekstrak kunyit putih (Curcuma zedoaria) terhadap kadar gula darah dan kolesterol. Penelitian eksperimental ini melibatkan 6 kelompok tikus dengan perlakuan yang berbeda, 2 kelompok kontrol yaitu : kelompok normal dan kelompok NaCMC 1%, dan 4 kelompok perlakuan dengan dosis 250 mg/KgBB, 500 mg/KgBB, 750 mg/KgBB, dan 2000 mg/KgBB. Kadar gula darah dan kolesterol diukur dengan spektrofotometri, setelah tikus diberi perlakuan selama 14 hari. Berdasarkan hasil uji yang telah dilakukan, dosis paling efektif untuk menurunkan kadar gula darah adalah 500mg/kgBB. Berdasarkan uji One Way Anova terdapat perbedaan KGD yang signifikan antara Kelompok Normal dan Na CMC 1% dengan EKP250, EKP500, EKP750, dan EKP2000 serta tidak terdapat perbedaan kolestrol yang signifikan antara Kelompok Normal dan Na CMC 1% dengan EKP250, EKP500, EKP750, dan EKP2000.
