Judul: Analisis Daya Saing Ekspor Lada Indonesia ke Negara Tujuan Ekspor.
Abstrak: Indonesia merupakan salah satu negara eksportir lada terbesar didunia. Amerika dan beberapa negara Uni Eropa merupakan negara tujuan ekspor lada Indonesia. Tujuan dari penelitian ini adalah untuk Menganalisis perkembangan ekspor lada Indonesia dan menganalisis daya saing ekspor lada Indonesia di negara tujuan ekspor pada periode tahun 2004-2018. Penelitian ini menggunakan metode Revelead Comparative Advantage (RCA), Export Product Dynamics (EPD), dan Indeks Spesialisasi Perdagangan (ISP). Hasil penelitian menunjukkan bahwa luas lahan dan produksi lada Indonesia mengalami penurunan, perkembangan ekspor lada Indonesia juga cukup berfluktuatif. Berdasarkan perhitungan RCA Indonesia memiliki daya saing atau keunggulan komparatif untuk ekspor ke Jerman, Belanda, Prancis, Italia, dan Belgia. Nilai EPD menunjukkan Indonesia berada pada posisi Retreat di negara Belanda, Jerman, dan Belgia. Sedangkan Indonesia berada pada posisi Rising Star di Italia, Falling Star di Prancis, dan Lost Opportunity di Amerika. Nilai ISP menunjukkan bahwa Indonesia mempunyai daya saing yang kuat sebagai pengekspor lada utuh.

Judul: Analisis Daya Saing Dan Faktor-Faktor Yang Memengaruhi Ekspor Lada Indonesia Ke Negara Tujuan Ekspor
Abstrak: Indonesia merupakan salah satu penghasil dan pengekspor lada dunia. Tujuan dari penelitian ini adalah untuk menganalisis keunggulan komparatif lada Indonesia di negara tujuan ekspor lada dengan menggunakan Revealed Comparative Advantage (RCA) dan analisis Export Product Dynamics (EPD) untuk menganalisis keunggulan kompetitifnya. Data panel statis untuk melihat faktor-faktor yang memengaruhinya. Hasil yang didapat dari analisis RCA dan EPD, bahwa komoditi lada Indonesia memiliki keunggulan komparatif yang kuat ke negara tujuan. Negara Singapura dan Inggris berada pada posisi Rising Star, negara Australia dan Vietnam berada pada posisi Falling Star, negara Amerika Serikat, Jerman, dan India berada pada posisi Lost Opportunity, dan negara Jepang berada pada posisi Retreat. Hasil penelitian dengan menggunakan panel data statis menunjukkan variabel GDP perkapita negara tujuan, harga ekspor lada Indonesia, produksi lada Indonesia, dan populasi berpengaruh signifikan terhadap nilai ekspor lada Indonesia, sedangkan nilai tukar rupiah terhadap mata uang negara tujuan tidak berpengaruh signifikan.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
