Judul: Dayasaing dan Permintaan Ekspor Produk Biofarmaka Indonesiadi Negara Tujuan Utama Periode 2003-2012
Abstrak: Permintaan obat herbal dunia semakin meningkat, tentunya diperlukan usaha yang lebih intensif agar pasokan bahan baku produk biofarmaka dapat terpenuhi. Penelitian ini bertujuan untuk melihat bagaimana daya saing yang terjadi antardua negara di dunia terhadap penyediaan produk ekspor serta menganalisis faktor yang memengaruhi permintaan ekspor produk biofarmaka dunia terhadap negara tujuan utama. Metode analisis yang digunakan dalam penenelitian ini adalah Revealed Comparative Advantage (RCA), Export Product Dynamics (EPD) dan Gravity Model. Periode waktu yang diteliti adalah rata-rata tahun 2003 hingga 2012. Hasil penelitian menyimpulkan bahwa Indonesia memiliki daya saing yang baik terhadap komoditi kunyit dan kayu gaharu apabila dibandingkan dengan negara pesaing berdasarkan analisis RCA dan EPD dengan posisi daya saing “Lost Oppportunity”. Hasil estimasi faktor yang memengaruhi permintaan produk biofarmaka adalah Real GDP, Real Exchange Rate, Population dan Economic Distance berdasarkan analisis gravity model, seluruh variabel indepeden berpengaruh secara signifikan terhadap dependen dan sesuai dengan hipotesis.

Judul: Faktor-faktor yang Memengaruhi Ekspor Tanaman Biofarmaka Indonesia
Abstrak: Indonesia as an agricultural country indicate that the agricultural sector has an important role in supporting the national economy . It can be seen from the the growing of Indonesian biopharmaca export to importing countries over the past seven years is tend to increase. The purpose of this paper is to describe the development of the export of Indonesian biopharmaca plants (ginger, turmeric, curcuma), to analyze the factors that affect the volume of exports Indonesian biopharmaca plants (ginger, turmeric, curcuma). The development of Indonesian exports of biopharmaca plants to importing countries during the years 2006-2012 are likely to increase. Overall the factors that influence the export of Indonesian biopharmaca plants is the export prices of Indonesian biopharmaca plants, economic distance, the exchange rate of Rupiah against U.S. dollar, and the export volume of the previous period. Overall the factors that affecting the export of Indonesian biopharmaca plants is export prices, economic distance the exchange rate of Rupiah against U.S. dollar and the export volume of the previous period

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
