Judul: Dampak guncangan harga minyak mentah dunia terhadap harga beras domestik (suatu analisis kointegrasi)
Abstrak: Rice is a substantial strategic and food comodity in Indonesia and also in some countries in the world, particularly in Asia. Therefore, the stability of rice price and the availability should be maintained, especially rice is also known as unstable commodity. Starting in 1994, Indonesia became a net importer of rice commodity, then, Indonesia‟s rice market is allegedly integrated with the world‟s rice market. Consequently, any changes or shock in the world‟s rice market, which is one of its shocks caused by world oil price shock, will affect the domestic rice market. The objectives of this study are: (1) to analyze factors that influence the domestic rice price, (2) to analyze the effect of changes on the world oil price shocks to the domestic rice price. The applicable method for this study is vector error correction model (VECM) with analysis tools are IRF, FEVD, and pass-through. The estimation results indicate that there is a cointegration in the models studied. In the short-term, factors (variables) that affect the domestic rice price are the price of imported rice, domestic rice price, and the price of crude oil. Besides, in the long run, factors (variables) that affect the domestic rice price are the price of imported rice, world rice price, and production rice. The variables that largely influence the domestic rice price are world rice price and price of imported rice. On the other hand, a variable that slightly affect is the total factor productivity (TFP).

Judul: Analysis of Rice Market Integration in Indonesia.
Abstrak: Beras merupakan komoditas pangan strategis dan termasuk barang inelastis yang memiliki permintaan tinggi di sepanjang tahun. Namun produksi yang bergantung pada musim tanam mengakibatkan harga komoditas beras menjadi tidak stabil sehingga terjadi selisih harga yang besar antara harga di tingkat petani produsen dan harga di tingkat konsumen akhir. Penelitian ini bertujuan untuk mengetahui pola pergerakan harga gabah-beras dan menganalisis integrasi pada pasar beras Indonesia. Analisis integrasi dilakukan dengan Vector Error Correction Model (VECM). Hasil analisis menunjukkan bahwa harga gabah lebih fluktuatif dibandingkan dengan harga beras eceran maupun beras grosir dan kebijakan pemerintah mengatur harga beras efektif menstabilkan harga gabah bulanan. Hasil analisis VECM menunjukkan bahwa antara pasar produsen dan pasar grosir tidak terjadi integrasi jangka panjang dan terintegrasi dalam jangka pendek. Antara pasar produsen dan pasar eceran tidak terintegrasi dalam jangka panjang maupun jangka pendek. Antara pasar grosir dan pasar konsumen terintegrasi baik dalam jangka panjang maupun jangka pendek., Rice is a strategic food commodity and an inelastic goods that have high demand throughout the year. However, rice production that depends on the growing season causes the price of rice to become unstable, resulting in a large price difference between the farmers price and the consumer price. This study aims to determine the pattern of grain-rice price movements and analyze the integration that occurs in Indonesian rice markets. Integration analysis was analyzed using Vector Error Correction Model (VECM). The analysis showed that grain price was more volatile than the retail and wholesale rice prices and the government's policy to regulate rice prices is effective in stabilizing monthly grain prices. The analysis result showed that the market integration in producers markets and wholesale market are not integrated in the long-term, but they are integrated in the short-term. There no integration between the producers and consumers in long or short-term. The wholesale markets and retail markets are integrated well in the long-term and short-term.

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before. This study was conducted to examine the characteristics of capsulae and trabecula of the Common Rousette (Rousettus amplexicaudatus).
