Judul: Faktor-Faktor yang Mempengaruhi Volume Impor dan Kebijakan Impor Bawang Merah (A. Ascalonicum L.) Indonesia
Abstrak: Shallot is a horticulture commodities that has a high economic value and a large market opportunity as a seasoning for a consumption of the household, the material for industry and to fulfill the export quota. This research analyze the factors that influence the volume of shallot import in Indonesia and formulate alternative policy strategies shallot imports in Indonesia. Multiple linear regression method showed that shallot import volume is significantly influenced by shallot import prices, exchanges rate Rupiah against U.S. Dollar and import tarif 25. Import tariff policies were set by the government during this time will increaseshallot imports to Indonesia. Furthermore, the import tarif still set low for the countries that do not bound by the special agreements that make the opportunity of shallot import is easier to Indonesia.

Judul: The Impact of Policies and Determinants of Indonesian Garlic Imports from China
Abstrak: Bawang putih merupakan komoditas hortikultura yang ditargetkan pemerintah untuk swasembada di tahun 2021 untuk memenuhi permintaan bawang putih nasional. Akan tetapi, produksi bawang putih domestik masih belum mampu memenuhi permintaan tersebut. Dengan demikian, sebagian besar kebutuhan akan bawang putih dalam negeri dipenuhi dengan melakukan impor bawang putih dari negara produsen bawang putih. Cina merupakan produsen bawang putih terbesar di dunia yang juga merupakan negara pengekspor utama bawang putih ke Indonesia. Penelitian ini bertujuan menganalisis pengaruh kebijakan dan faktor penentu impor bawang putih Indonesia dari Cina tahun 1996 hingga 2019 menggunakan analisis regresi linier berganda dengan metode Ordinary Least Square (OLS). Berdasarkan hasil estimasi, variabel yang berpengaruh signifikan terhadap volume impor bawang putih dari Cina adalah harga bawang putih impor, harga bawang merah domestik, populasi Indonesia, dan kebijakan penghapusan tarif. Sedangkan nilai tukar riil dan kebijakan RIPH tidak berpengaruh signifikan terhadap volume impor bawang putih dari Cina., Garlic is a horticultural commodity targeted by the government for self-sufficiency in 2021 to fulfill the national demand. However, garlic production is still unable to meet the domestic demand. Thus, most of the domestic demand for garlic has been fulfilled by importing garlic from garlic producing countries. China is the largest producer of garlic in the world and is the main exporter of garlic to Indonesia. This research aims to analyze the policies impact and determinants of Indonesian garlic imports from China since 1996 to 2019 using multiple linear regression analysis with the Ordinary Least Square (OLS) method. Based on the estimation results, the variables that significantly affect the volume of imported garlic from China are the price of imported garlic, the price of domestic shallots, the population of Indonesia, and tariff elimination policy. Meanwhile, the real exchange rate and the RIPH policy did not significantly affect the import volume of garlic from China.

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.
