Judul: Analisis Pengaruh Pariwisata terhadap Perekonomian Negara-negara ASEAN+4
Abstrak: As a region which has a great tourism potential, ASEAN and China, India, Japan, and South Korea (ASEAN+4) cooperate to encourage the performance of the tourism sector. The tourism sector plays an important role in increasing household income and employment in the region. However, the development of the tourism sector in the countries of ASEAN+4 fluctuated. Therefore, this study aimed to analyze the affect of tourism on the economy and the factors that affect tourist arrivals in ASEAN+ 4. Static panel data used to analyze the data obtained from the 13 ASEAN+4 during the period 2005 to 2012. The results of this study showed tourist spending, investment tourism sector, and total government spending affect the increase in Gross Domestic Product (GDP) per capita rill. However, the level of corruption negatively affect the real GDP per capita. Furthermore, the results of this study indicate factors affecting the increase in tourist arrivals to ASEAN+4 countries is a public service, the total trade, life expectancy and gross domestic product in the country. However, the price factor influence on the decline in tourist arrivals to the region.

Judul: Pengaruh Sektor Pariwisata terhadap Pertumbuhan Ekonomi Negara Asia Pasific Cooperation (APEC) Periode 2010-2015.
Abstrak: Pariwisata adalah salah satu potensi yang dimiliki oleh negara Asia Pasific Economic Cooperation (APEC). APEC telah melakukan kerjasama di bidang pariwisata lewat pembentukan Tourism Working Group di tahun 1991 dan pengimplementasian program ini dimulai tahun 2001 lewat deklarasi Seoul. Walaupun telah dibuat program kerja di sektor pariwisata namun kontribusi sektor pariwisata di negara APEC masih fluktuatif. Maka dari itu penelitian ini bertujuan untuk menganalisis pengaruh pariwisata terhadap petumbuhan ekonomi negara APEC pada periode 2010-2015 serta meneliti juga faktor-faktor yang memengaruhi GDP pariwisata negara APEC pada periode yang sama. Penelitian ini menggunakan pendekatan data panel. Hasil penelitian menunjukan bahwa pengeluaran pemerintah, investasi kapital serta pengeluaran wisatawan pada sektor pariwisata berpengaruh positif pada pertumbuhan ekonomi. Kemudian GDP pariwisata negara APEC dipengaruhi oleh penyerapan tenaga kerja, pengeluaran wisatawan domestik disektor pariwisata, kestabian politik, dan GDP per kapita.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
