Judul: Cervical Cancer Histopathology Image Classification with Transfer Learning
Abstrak: Kanker mulut rahim (serviks) adalah kanker dengan jumlah kasus terbanyak kelima pada wanita di seluruh dunia dan merupakan masalah kesehatan perempuan di Indonesia dengan angka kejadian dan kematiannya yang tinggi. Tes skrining pap smear manual yang berfungsi sebagai pencegahan dan deteksi awal kanker serviks masih rawan akan terjadinya kesalahan observasi. Penelitian ini bertujuan untuk membuat model convolutional neural network dengan metode transfer learning untuk identifikasi kanker serviks pada citra pap smear. Data yang digunakan pada penelitian ini adalah dataset open source SIPaKMeD yang mengandung 4049 citra sel serviks normal, abnormal, dan jinak. Penelitian ini dilakukan melalui beberapa tahapan yaitu praproses data, pembagian data, hyperparameter tuning, pembuatan model prediksi, dan evaluasi model. Penelitian ini menghasilkan tiga model CNN berbeda dengan akurasi terbaik sebesar 99,04%., Cervical cancer is a cancer with the fifth highest number of cases in women worldwide and is a health problem in Indonesia with high incidence and death rate. Manual pap smear screening tests that function as prevention and early detection of cervical cancer are still prone to observation errors. This study aims to create a convolutional neural network with transfer learning method to identify cervical cancer on pap smear images. The data used in this study are the open source dataset SIPaKMeD that contains 4049 normal, abnormal, and benign cervical cell images. The study was carried out through several stages which are data preprocessing, data splitting, hyperparameter tuning, prediction model making, and model evaluation. Three different CNN models were made, having the best accuracy of 99.04%.

Judul: Classification of Cervical Cancer on Pap Smear  Image Using CNN and SVM
Abstrak: Kanker serviks menduduki peringkat empat untuk jenis kanker yang umum dijumpai pada wanita di seluruh dunia dan merupakan penyakit dengan angka kematian yang cukup tinggi di Indonesia. Tes skrining pap smear merupakan salah satu usaha pencegahan dini untuk mendeteksi kanker serviks. Tes skrining yang dilakukan secara manual masih rentan terjadi kesalahan observasi. Penelitian ini bertujuan untuk membuat model convolutional neural network dan support vector machine untuk identifikasi kanker serviks melalui citra pap smear. Data yang digunakan dalam penelitian ini adalah 4049 citra sel bersumber dari SIPaKMeD yang terbagi menjadi lima kelas berdasarkan tingkat keganasan kanker. Model convolutional neural network digunakan untuk melakukan ekstraksi fitur pada citra pap smear dan support vector machine digunakan untuk melakukan proses klasifikasi. Hasil penelitian ini adalah empat buah model klasifikasi kanker serviks pada citra pap smear menggunakan arsitektur Resnet50 dan algoritme support vector machine dengan skenario yang berbeda. Model klasifikasi dengan performa terbaik menghasilkan akurasi sebesar 97,09%., Cervical cancer is ranked fourth for a type of cancer that is commonly found in women worldwide and is a disease with a high mortality rate in Indonesia. Pap smear screening test is one of the early prevention efforts to detect cervical cancer. Manual screening test are still prone to observation errors. This study aims to create a convolutional neural network model and support vector machine model to identify cervical cancer through pap smear images. The data used in this study were 4049 cell images sourced from SIPaKMeD which were divided into 5 classes based on the level of cancer malignancy. The convolutional neural network model is used to extract features on the pap smear image and the support vector machine is used to carry out the classification process. The results of this study are four cervical cancer classification models on pap smear images using Resnet50 architecture and support vector machine algorithms with different scenarios. The classification model with the best performance has an accuracy of 97.09%.

Judul: Sectoral Effects Of Monetary Policy
Abstrak: The purposes of this study are three folds: (1) identifying which channels are effective for transmission of monetary policy; (2) assessing whether the transmission mechanisms at industry level are consistent with that at aggregate level; and (3) explaining why and how a channel becomes effective. The analyses are facilitated impulse response function (IRF) derived from a vector autoregression (VAR) model. Three channels are identified in this study: interest rate, real credits and exchange rate channels. The IRF results show that exchange rate is the only effective channel in affecting aggregate output and at least in five industries (the manufacturing industry; the construction industry; the trade, hotel, and restaurants industry; the transport and communication industry; and the finance, real estate, and business services industry). Meanwhile, the other two channels are not effective at aggregate and all industry. This finding suggests that there is some form of consistency between aggregate effects and industry effects. Moreover, the effect of real depreciation tend to be contractionary and thus supporting the idea of Krugman and Taylor (1976) among others. Output contraction seems to be associated with inflationary effect of the depreciation. This is a truly Keynesian type demand side story: following a real currency depreciation, purchasing power tends to weaken which then soaks the aggregate demand.
