Abstrak: Crude Palm Oil (CPO) is a vegetable oil derived from palm oil . Indonesian palm oil production are not accompanied by high domestic processing but many serve as export commodities. However, based on data from the Ministry of Industry in 2009 to 2011 the number of Indonesian exports gradually decreased. The decline in Indonesia palm oil exports in the period 2009-2011 due to external and internal factors. External factors due to the global economic crisis, and the saturation of the production of palm oil in the world market. Internal factors due to domestic palm oil downstream industry developing. This study was restricted to examining the internal factors causing the decline in Indonesia palm oil exports. The purpose of this study is to analyze the production of palm oil and palm oil production of downstream products, as well as to analyze the factors that affect the demand for downstream palm oil industry in Indonesia for palm oil. This study uses time series data from 1991 to 2011 year. Indonesian palm oil demand model by palm oil downstream industry estimated by multiple linear regression models and estimation methods Ordinary Least Squares (OLS). Indonesian palm oil demand by downstream industries is derived demand (derived demand) of the company's profits that allegedly affected by input prices (real prices of domestic palm oil), output prices (real prices of downstream products) and total output (production of downstream products). The results showed a decrease in palm oil exports indicates that the domestic downstream industry began to flourish. Demand for palm oil in Indonesia's downstream industries significantly affected by the real price of inputs and the production of downstream products. In order to increase the production of cooking oil, margarine, soaps, and fatty acid and palm oil consumption by the downstream industry, the government should facilitate the loan interest rate subsidies and implementing tax holiday. The government should impose a tax or non-low duty on exports of palm oil downstream products.

Abstrak: Indonesia as the biggest crude palm oil and palm kernel oil exporter in the world, can not continuosly keep on exporting the crude palm oil and palm kernel oil. Indonesia needs to develop the downstream production of crude palm oil and palm kernel oil industry to give the added value, to employ many labors and also as the environmental recovery function. Therefore, it’s needed a right policy from the government to support the downstream production of crude palm oil and palm kernel oil industry. The purposes of this research are: (1) to analyze the development of Indonesia’s palm oil export; (2) to analyze the development of Indonesia’s palm kernel oil export; (3) to analyze the affecting factors of Indonesia’s palm oil export; (4) to analyze the affecting factors of Indonesia’s palm kernel oil export. This research is using time series data from 1990-2011. The Indonesia’s crude palm oil and palm kernel oil export model was estimated by the doubled linear regresion with Ordinary Least Square (OLS) estimation method. Export models were divided into 6 single formulations, which are Indonesia’s palm oil export with destination country to India, Netherlands, and Singapore, also another single formulations of Indonesia’s palm kernel oil export with destination country to Malaysia, Netherlands and China. The result of this research indicates in a short period the tax rate would be an important instrument in order to limit the Indonesia’s palm and palm kernel oil export on the Indonesia’s downstream production of palm and palm kernel industry development. The facilities which must be built by the government in order to support the development of the downstream industry of crude palm oil and palm kernel oil are infrastructure development, application of tax holiday, and also by deleting the local regulation which blocks the development of the downstream industry of crude palm oil and palm kernel oil.

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%.
