Judul: Determinants of Indonesian Tire Exports to the Latin American Region
Abstrak: Kawasan Amerika Latin merupakan kawasan yang memiliki peluang yang besar pada pasar komoditas ban, hal ini terbukti dari meningkatkan permintaan ban dari negara-negara kawasan Amerika Latin. Walaupun demikian, Indonesia hanya berhasil menempati posisi keempat sebagai eksportir ban terbesar di kawasan Amerika Latin setelah China, Thailand, dan India padahal Indonesia memiliki sumber daya yang memadai untuk komoditas ini. Penelitian ini berfokus ekspor komoditas ban (HS 4011) di kawasan Amerika Latin selama periode 2008-2021. Perluasan pasar ekspor tidak hanya bertujuan untuk menjadikan Indonesia sebagai eksportir utama tetapi juga bertujuan untuk menghindari ketergantungan pada pasar negara tujuan utama pada saat terjadi guncangan ekonomi global. Daya saing ekspor ban Indonesia ke kawasan Amerika Latin dianalisis dengan menggunakan RCA, EPD, dan gabungannya melalui x-model, serta analisis gravity model untuk melihat faktor-faktor yang memengaruhi volume ekspor ban Indonesia ke kawasan Amerika Latin. Hasil analisis menunjukkan daya saing komoditas ban Indonesia secara umum memiliki daya saing kuat serta memiliki sifat dinamis yang mencerminkan fleksibilitas dan adaptabilitas komoditas ban dalam menghadapi lingkungan pasar yang berubah-ubah pada pasar kawasan Amerika Latin. Faktor- faktor yang memengaruhi permintaan ekspor adalah jarak ekonomi, pendapatan perkapita negara tujuan, dan indeks harga konsumen., The Latin American region is a region that has great opportunities in the tire commodity market, this is proven by the increasing demand for tires from countries in the Latin American region. However, Indonesia only managed to occupy the fourth position as the largest tire exporter in the Latin American region after China, Thailand and India even though Indonesia has adequate resources for this commodity. This research focuses on tire commodity exports (HS 4011) in the Latin American region during the 2008-2021 period. Expanding the export market not only aims to make Indonesia a major exporter but also aims to avoid dependence on the market of the main destination country when global economic shocks occur. The competitiveness of Indonesian tire exports to the Latin American region is analyzed using RCA, EPD, and their combination through x-model, as well as gravity model analysis to see the factors that affect the volume of Indonesian tire exports to the Latin American region. The results of the analysis show that the competitiveness of Indonesian tire commodities in general has strong competitiveness and has a dynamic nature that reflects the flexibility and adaptability of tire commodities in facing changing market environments in the Latin American market. Factors that influence export demand are economic distance, per capita income of the destination country, and the consumer price index.

Judul: Analisis Daya Saing dan Faktor-faktor yang Memengaruhi Ekspor Spare Parts Indonesia ke Kawasan Amerika Latin
Abstrak: Spare parts industry is one of growing value chain industries, it also has high value, and potency in Indonesia. Latin America region is one of nontraditional export market that has potency for Indonesia’s diversification of export destinations especially for spare parts products. This study aims to analyze the competitiveness and the factors affect Indonesia’s spare parts export to Latin American region from 2009 to 2013. The methods used in this paper are the Constant Market Share Analysis (CMSA) and gravity model with panel data methods. The CMSA results indicate that the average of competitiveness Indonesia’s spare parts export to Latin American period 2009 to 2013 influenced by the competitiveness effect. The gravity model results indicate factors that have significant impact to the value of Indonesia’s spare parts export are real GDP interaction of exporters and importers country, exchange rate importers country to Dollar, and export prices. Meanwhile, economic distance and import tariff have no significant impact on the value of Indonesia’s spare parts export.

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.
