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: 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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
