Judul: Analysis of The Effect of Macroeconomic Factors and Internal Factors of Sukuk on The Fluctuation of Sukuk Prices
Abstrak: Sukuk merupakan salah satu bentuk investasi yang sesuai dengan prinsip ajaran Islam. Ada banyak faktor yang memengaruhi harga sukuk, seperti faktor makroekonomi dan faktor internal. Pada karya ilmiah ini dianalisis bagaimana pengaruh faktor-faktor makroekonomi seperti Jakarta Islamic Index, kurs Rupiah terhadap Dollar Amerika Serikat, harga emas, dan harga minyak mentah serta faktor-faktor internal sukuk seperti harga sukuk SR-009 dan imbal hasil sukuk SR009 terhadap harga sukuk SR-009. Analisis tersebut dilakukan dengan membentuk model menggunakan Vector Error Correction Model (VECM). Selanjutnya, model tersebut diimplementasikan dalam Fungsi Respon Impuls atau Impulse Response Function (IRF) dan Forecast Error Variance Decomposition (FEVD) untuk melihat pengaruh jangka panjang seluruh faktor terhadap harga sukuk SR-009. Hasil yang diperoleh ialah seluruh faktor saling terkointegrasi atau memiliki hubungan jangka panjang bagi fluktuasi harga sukuk SR-009. Selain itu, seluruh faktor juga memiliki hubungan kausalitas Granger atau hubungan timbal balik dengan harga sukuk SR-009., Sukuk is a form of investment in accordance with the Islamic principles. There are many factors that influence the sukuk price, such as macroeconomic factors and internal factors of sukuk. In this research paper it is analyzed how the influence of macroeconomic factors such as Jakarta Islamic Index, USD exchange rate, gold prices, and crude oil prices, as well as internal factors of sukuk such as prices and yileds on the sukuk SR-009 prices. The analysis was carried out by forming a model using the Vector Error Correction Model (VECM). Furthermore, the model is implemented in the Impulse Response Function (IRF) and Forecast Error Variance Decomposition (FEVD) to see the long-term relationship of all factors on the sukuk SR-009 prices. The result shows that all factors are cointegrated or have a long-term relationship for the fluctuation of the sukuk SR009 prices. In addition, all factors have a Granger causallity or reciprocal relationship with the sukuk SR-009 prices.

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: Penangkaran Kupu Pachliopta aristolochia (Papilionidae: Lepidoptera) di Screen House dan Laboratorium
Abstrak: This study aims to domesticate of Pachliopta aristolochia in screen house and laboratory. Sixty-seven P. aristolochiae were released into the screen house. From six pairs mated butterflies produced two hundred and sixty eggs layed. Forty eggs were studied in the research. Twenty larvae were maintained in screen house and the other twenty larvae were maintained in the laboratory. Twenty larvae that developed into pupa in the screen house, were moved into the laboratory. The other twenty larvae were maintained in the laboratory. The twenty larvae in the screen house turned into a pupa and only nineteen butterflies were in normal condition, with sex ratio 8/11. Larvae in the laboratory developed into twenty normal pupas and produced fifteen normal butterflies with a sex ratio 11/4. All butterflies in the screen house can continue to develop and reproduce as long as Aristolochia tagala as larvae food and nectar of flower as butterfly food are available. The life cyle of P. aristolochiae in screen house from egg until pupa was 35,9±6,76 days.
