Abstrak: Penerbitan Sukuk Negara masih berada pada kisaran 20-30 persen setiap tahunnya dari total Surat Berharga Negara yang diterbitkan serta terdapat beberapa penjualannya yang tidak mencapai target pemerintah. Sebagai negara Muslim terbesar di dunia, Indonesia hanya menyumbang 13.38 persen total penerbitan Sukuk Negara di dunia di bawah Malaysia sebesar 32.82 persen dan Arab Saudi sebesar 31.94 persen. Penelitian ini bertujuan untuk menganalisis pengaruh guncangan makroekonomi terhadap perkembangan Sukuk Negara yang berdenominasi rupiah dari tahun 2014 sampai 2019. Berdasarkan metode analisis Vector Error Correction Model (VECM) diperoleh hasil bahwa Sukuk Negara merespon positif guncangan produk domestic bruto, imbalan deposito mudharabah dan Jakarta Islamic Index (JII). Sedangkan Sukuk Negara merespon negatif inflasi, suku bunga acuan dan nilai tukar rupiah. Variabel yang memberikan kontribusi dominan dalam menjelaskan keragaman perkembangan Sukuk Negara secara berurutan adalah JII, nilai tukar rupiah dan suku bunga acuan., The issuance of Sovereign Sukuk is still in the range of 20-30 percent each year of the total Government Securities issued and there are several sales that do not reach the government’s target. As the largest Muslim country in the world, Indonesia only contributed 13.38 percent of the total issuance of Sovereign Sukuk in the world, under Malaysia at 32.82 percent and Saudi Arabia at 31.94 percent. This study aims to examines the impact of macroeconomic shocks on the development of local currency Sovereign Sukuk from 2014 to 2019. Based on the Vector Error Correction Model (VECM) analysis method, it is found that Sovereign Sukuk respond positively to the shocks of real gross domestic product, mudharabah deposits return rate, and Jakarta Islamic Index (JII). Meanwhile the Sovereign Sukuk respond negatively to the shock of inflation, policy rate, and exchange rate. The three variables that made dominant contribution in explaining the variation of development of Sovereign Sukuk were JII, exchange rate and policy rate.

Judul: Impact  of  macroeconomic  variables  towards  yield‟s  sovereign  sukuk  retail  series  in  Indonesia
Abstrak: Penelitian ini bertujuan menganalisis pengaruh variabel makroekonomi terhadap tingkat imbal hasil Sukuk Ritel di Indonesia dan mengidentifikasi variabel yang paling dominan berpengaruh terhadap tingkat imbal hasil Sukuk Ritel dengan menggunakan metode Vector Error Correction Model (VECM). Variabel yang digunakan dalam penelitian ini adalah yield Sukuk Ritel SR003, tingkat suku bunga SBI, Industrial Production Index (IPI), Indeks Harga Konsumen (IHK), dan nilai tukar rupiah terhadap dolar (Exrate). Hasil analisis menunjukkan bahwa dalam jangka panjang, SBI memberikan pengaruh positif secara signifikan terhadap yieldsukuk ritel, sedangkan IPI dan IHK berpengaruh negatif secara signifikan terhadap yield sukuk ritel. Variabel Exrate tidak berpengaruh signifikan terhadap yield sukuk ritel. Guncangan yang terjadi pada SBI, IHK, dan Exrate direspon positif oleh yield sukuk ritel sedangkan guncangan pada IPI direspon negatif oleh yield sukuk ritel dan akan stabil dalam jangka panjang. Urutan kontribusi guncangan yang paling dominan memengaruhi yield sukuk ritel yaitu yield sukuk ritel itu sendiri, IPI, SBI, dan IHK., This research aims to analyze the impact of macroeconomic variables towards yield of sukuk retail in Indonesia and identify the most dominant variable effect towards yield of sukuk retail using Vector Error Correction Model (VECM). The variables observed in this research are yield of retail sukuk SR003, the interest rate of SBI, Industrial Production Index (IPI), Consumer Price Index (CPI), and Exchange Rate Rupiah-United States Dollar. The result shows that in the long run, SBI significantly positive effect on the yield of Retail Sukuk, while IPI and IHK significantly negative effect on the yield of Retail Sukuk. Variable Exrate has no significant effect on the yield of Retail Sukuk. Shocks that occur in SBI, CPI, and Exrate positively responded by yield of Retail Sukuk, while shocks to IPI negatively responded by yield of Retail Sukuk and will be stable in the long term. The order of the dominant contribution of the shocks affecting the yield of Retail Sukuk is yield of Retail Sukuk itself, IPI, SBI, and CPI.

Judul: Graphology Analysis Based on Letter a and t Using Perceptron.
Abstrak: Graphology or handwriting analysis is a method of identifying, analyzing, evaluating, and understanding personality through the strokes and patterns revealed by handwriting. A person who can analyze handwriting is called a graphologist. A graphologists can be subjective in their assesments different graphologist can have different analysis of the same handwriting. Therefore, a computer technology may help to minimize the subjectivity. This research used perceptron to analyze personality based on handwriting. Perceptron is one method of neural network. This research analyze two letters to letter a and t image. Letter a are represented by 135 images, consisting of 81 images as training data and 54 images as testing data. There are 150 images used for t images, consisting of 90 images as training data and 60 images as testing data.There are 5 experiments consisting of 2 experiments for letter a and 3 experiments for letter t. The result is the character of each class letter a and t where each parameters there are 3 classes. The accuracy of letter t and letter a was 55% and 88.89% respectively.
