Judul: Analisis Daya Saing dan Dampak Ekspor Perabotan Indonesia ke CARICOM
Abstrak: Indonesia tidak luput dari dampak guncangan ekonomi akibat pandemi. Perabotan adalah salah satu produk unggulan komoditas hasil industri di Indonesia. Ketergantungan pasar ekspor pada negara tujuan utama (tradisional) mendorong Indonesia melakukan diversifikasi pasar. Salah satu upaya diversifikasi adalah dengan menjajaki kemungkinan perundingan perdagangan dengan CARICOM. Penelitian ini bertujuan untuk menganalisis daya saing, dinamika dan determinan ekspor perabotan Indonesia ke CARICOM. Metode penelitian yang digunakan dalam penelitian ini adalah RCA, EPD, X-Model, dan regresi data panel. Hasil analisis RCA menunjukkan perabotan Indonesia berdaya saing tinggi. Hasil analisis EPD menunjukkan pengembangan pasar rising star dan lost opportunity. Hasil analisis X-Model menunjukkan pengembangan pangsa pasar optimis dan potensial. Hasil analisis regresi data panel menunjukkan bahwa variabel yang berpengaruh positif dan signifikan yaitu GDP riil negara tujuan, nilai tukar dan RCA. Variabel yang berpengaruh negatif dan signifikan yaitu populasi dan dummy Covid-19. Sementara variabel yang tidak signifikan yakni harga ekspor., Indonesia has not escaped the impact of the pandemic. Furniture is one of top commodity products in Indonesia. The dependence of the export market on the main (traditional) destination countries encourages Indonesia to diversify its markets. One of Indonesia’s efforts to diversify the export market is by exploring the possibility of trade negotiations with CARICOM. This study aims to analyze the competitiveness, dynamics, and determinants of furniture from Indonesia to CARICOM. The research methods used in this study are RCA, EPD, X-Model, and panel data regression. The results of RCA analysis show that Indonesian furniture is highly competitive. The results of the EPD analysis show the development of the rising star market and lost opportunity. The results of the X-Model analysis show the development of optimistic market share and potential market share. Panel data regression analysis results show that the positive and significant influential variables are the real GDP of the target country, exchange rate, and RCA. The negative and significant influencing variables are population and dummy Covid-19. While the non-significant variables are export prices.

Judul: Diversification of Indonesian Export Markets to SICA: Competitiveness and Export Determinants of Main Commodities
Abstrak: Pandemi Covid-19 yang melanda seluruh negara membuat perekonomian negara Indonesia terkontaksi sebesar 2,07 % pada tahun 2020 kemudian tumbuh positif pada tahun 2021, pertumbuhan tertinggi disumbang dari sisi pengeluaran yang dicapai oleh komponen ekspor barang dan jasa. Central American Integration System (SICA) merupakan organisasi yang terdiri dari 8 negara di Kawasan Amerika Tengah yang memiliki populasi dan GDP per kapita yang cukup tinggi. Tingginya GDP per kapita menunjukkan daya beli yang tinggi sehingga dapat menjadi peluang bagi Indonesia untuk terus meningkatkan ekspor ke pasar SICA. Penelitian ini bertujuan untuk mengetahui daya saing dan determinan komoditas unggulan. Metode penelitian yang digunakan RCA, EPD, X-Model dan regresi data panel. Analisis regresi menunjukkan variabel yang berpengaruh positif dan signifikan yaitu GDP dan populasi negara importir pada komoditas HS 40, HS 48, dan HS 87, populasi Indonesia pada komoditas HS 48, FDI pada komoditas HS 87, RCA pada semua komoditas. Variabel yang berpengaruh negatif dan signifikan yaitu dummy Covid pada komoditas HS 48 dan 87. Adapun nilai tukar tidak berpengaruh signifikan., The Covid-19 pandemic that hit all countries caused the Indonesian economy to contract by 2,07% in 2020 and then expand in 2021. The highest growth was contributed by the expenditure side which was achieved by the component of exports of goods and services. The Central American Integration System (SICA) is an organization consisting of 8 countries in the region of Central America, which has a fairly high population and level of GDP per capita. The high level of GDP per capita shows high purchasing power, which indicates an opportunity for Indonesia to continue to increase exports to the SICA market. This study aims to determine the competitiveness and determinants of superior commodities. The research method used is RCA, EPD, X-Model and panel data regression. Regression analysis shows that the variables that have a positive and significant effect are GDP and the population of the destination country on HS 40, HS 48, and HS 87 commodities, the Indonesian population on HS 48 commodities, FDI on HS 87 commodities, and RCA on all commodities. The variable that has a negative and significant effect is the Covid dummy on HS 48 and 87 commodities. The exchange rate has no significant effect.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
