Judul: Analisis Alasan Penolakan Produk Pangan Ekspor Indonesia Oleh Amerika Serikat Dan Eropa Selama Tahun 2002-2010
Abstrak: Many detention and refusal case of food-product in foreign countries was occurring on each year. Indonesia as one of the country which exporting food-product to the overseas, often having detention and refusal case of food-product in United States and Europe. During the years of 2002-2010, Indonesia had experienced a case of rejection of food products in United States about 2608 cases and in Europe about 35 cases. Fishery products are a product with the highest number of rejection; it is about 1300 cases in United States and about 12 cases in Europe. The development in the case of rejection for food products that occurs every year during the years 2002-2010 showed a fluctuating growth. Based on the pareto chart, it is determined that the main problem of food products rejection cases that occurred in the US and Europe on fishery products is filthy and mercury. There are 2 factors that caused these problems based on the Ishikawa diagram. Those factors are the environments and humans.

Judul: Determinants of Indonesian Fishery  Commodities and Products Export Rejection by The United States and The  European Union
Abstrak: Ikan dan produk perikanan Indonesia merupakan komoditas strategis berorientasi ekspor. Neraca perdagangannya menunjukkan tren yang positif pada periode 2012-2020. Berdasarkan nilai ekspor tahun 2016-2020, Amerika Serikat dan Uni Eropa termasuk lima besar negara tujuan utama ekspor hasil perikanan Indonesia. Peningkatan nilai ekspor Indonesia di negara tersebut selalu diiringi dengan kasus penolakan ekspor. Penelitian ini bertujuan untuk menganalisis perkembangan penolakan ekspor, menganalisis alasan penolakan ekspor, dan menganalisis faktor-faktor yang memengaruhi penolakan ekspor. Metode analisis yang digunakan adalah analisis Unit Rejection Rate, Relative Rejection Rate, Regresi Poisson (GLMM.ZINB), dan analisis deskriptif. Hasil penelitian menunjukkan bahwa nilai URR dan RRR Indonesia di sepuluh negara mengalami penurunan dan hanya di Italia yang mengalami peningkatan. Penurunan nilai URR dan RRR menandakan adanya perbaikan compliance terhadap keamanan pangan di negara mitra, demikian sebaliknya. Share penolakan lebih tinggi dibandingkan share nilai ekspor di sebelas negara, artinya Indonesia masih perlu meningkatkan food safety dan kualitas kinerja ekspor. Tuna segar paling banyak ditolak di Amerika Serikat dan swordfish di Uni Eropa. Filthy (54,97%) menjadi penyebab penolakan tertinggi di Amerika Serikat dan mercury (54,41%) di Uni Eropa. Variabel jarak geografis berpengaruh positif dan signifikan terhadap penolakan ekspor perikanan Indonesia. Untuk mengatasi permasalahan jarak geografis, dapat melakukan perbaikan logistic performance., Indonesian fish and fishery products are export-oriented and strategic commodities. The trade balance showen a positive trend in the period 2012-2020. Based on the export value for 2016-2020, the United States and the European Union are among the top five main export destinations for Indonesian fishery products. The increase in the value of Indonesia's exports in these countries is always accompanied by cases of export refusal. This study aims to analyze the development of export refusal, analyze the reasons for export refusal, and analyze the factors that influence export refusal. The analytical methods used are Unit Rejection Rate, Relative Rejection Rate, Poisson Regression (GLMM.ZINB) analysis, and descriptive analysis. The results showed that Indonesia's URR and RRR values in ten countries decreased and only Italy experienced an increase. The decrease in URR and RRR values indicates an improvement in compliance with food safety in partner countries, and vice versa. The share of rejection is higher than the share of export value in eleven countries, meaning that Indonesia still needs to improve food safety and the quality of export performance. Fresh tuna is the most rejected in the United States and swordfish in the European Union. Filthy (54,97%) was the highest cause of rejection in the United States and mercury (54,41%) in the European Union. The geographical distance variable has a positive and significant effect on the rejection of Indonesian fishery exports. To overcome the problem of geographical distance, can improve logistics performance.

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%.
