Judul: Analisis Daya saing dan Faktor-Faktor yang Mempengaruhi Produksi Susu di Indonesia.
Abstrak: The aims of this study are (1) to analyze the development of milk industry in Indonesia, (2) to analyze the competitiveness of Indonesian milk, and (3) to analyze the factors that affect milk production in Indonesia. Data was from the Central Statistics Agency (BPS), the Directorate General of Animal Husbandry, Joint Cooperative Milk Indonesia (GKSI), International Financial Statistics (IFS) and Commodity Trade Statistics Database (Comtrade). This study used time series yearly data 2002 to 2010 of volume of milk production, domestic milk prices, corn prices and the number of cows. The method to analyze the competitiveness of Indonesian milk is Porter's Diamond approaches. Porter's Diamond analysis indicates a fundamental weakness of domestic milk competitiveness lies in the condition factor, supporting and related industries, government intervention, strategy structure and rivalry. Conversely, factors thought to contribute greatly to the condition competitiveness is demand conditions. The method to determine the factors that affect milk production in Indonesia is the panel data regression. The result that milk production is significantly affected by number of cows and not significantly affected by price of domestic milk and price of corn.

Judul: Analisis Ketergantungan Impor dan Faktor-faktor yang Memengaruhi Impor Produk Susu Indonesia
Abstrak: Kenaikan impor susu menunjukkan Indonesia semakin mengalami ketergantungan terhadap produk susu impor. Volume impor terkait dengan tahap pertumbuhan produk pada suatu negara. Rendahnya tahap pertumbuhan produk semakin meningkatkan kebutuhan impor produk. Namun, pertumbuhan impor susu Indonesia tidak berdasarkan besarnya defisit susu dalam negeri Penelitian memiliki tujuan untuk: (1) menganalisis tingkat ketergantungan dan karakteristik impor susu Indonesia; (2) menganalisis tahap pertumbuhan produk susu Indonesia; dan menganalisis faktor-faktor apa saja yang mempengaruhi impor susu Indonesia. Penelitian ini menggunakan jenis data sekunder dalam bentuk data panel; yang terdiri dari time series bulanan tahun 2014 hingga tahun 2018 dan data cross section dari enam negara yakni Indonesia, Amerika Serikat, Australia, Selandia Baru, Belgia dan Perancis. Metode penelitian menggunakan metode Import Dependency Ratio (IDR) untuk menanalisis tingkat ketergantungan impor Indonesia pada produk susu impor; metode derajat keterbukaan impor (DKI) dan derajat konsentrasi impor untuk menganalisis karakteristik impor produk susu Indonesia; metode Indeks Spesialisasi Perdagangan (ISP) untuk menganalisis tahap pertumbuhan produk susu Indonesia; dan regresi data panel untuk menganalisis determinan impor dengan pendekatan gravity model. Hasil penelitian menunjukkan bahwa Indonesia memiliki ketergantungan yang tinggi untuk produk susu; dengan rata-rata sebesar 40,42 persen kebutuhan susu Indonesia dipenuhi dari impor. Namun, derajat keterbukaan impor susu Indonesia masih relatif rendah (nilai DKI 0,14). Artinya, pembiayaan untuk impor susu masih dapat dilakukan. Sehingga, kebijakan impor susu Indonesia boleh diteruskan. Tahap pertumbuhan produk susu kode HS 0402104100 sebagai bahan baku industri susu dalam negeri masih sangat rendah. Demikian, menunjukkan bahwa perkembangan industri susu Indonesia untuk HS 0402104100 masih rendah. Industri susu dalam negeri masih belum mampu untuk menyediakan produk susu untuk bahan baku industri pada tahap selanjutnya dan mendorong pemenuhan bahan baku industri susu nasional harus dipenuhi dari impor. Faktor-faktor yang secara signifikan memengaruhi impor produk susu Indonesia adalah: (1) dummy kesamaan keanggotaan kesepakatan perdagangan antara Indonesia dan negara asal impor, (2) nilai tukar antara Rupiah dengan mata uang negara asal impor, (3) tingkat ketergantungan impor susu Indonesia dari negara asal impor, dan (4) volume total ekspor susu Indonesia. Hal ini menunjukkan bahwa impor produk susu Indonesia tidak hanya disebabkan besarnya defisit susu dalam negeri, namun juga secara signifikan disebabkan oleh adanya kesepakatan perdagangan dan perkembangan industri susu dalam negeri., The increase in milk imports shows that Indonesia is increasingly dependent on imported milk products. Import volume is related to the stage of product growth in a country. The low stage of product growth increases the need for product imports. However, the growth of Indonesian milk imports is not based on the large deficit in domestic milk The research aims to: (1) analyze the level of dependence and characteristics of Indonesian milk imports; (2) to analyze the growth stages of Indonesian milk products; and analyze what factors influence the import of Indonesian milk. This study uses secondary data in the form of panel data; which consists of monthly time series from 2014 to 2018 and cross section data from six countries, namely Indonesia, the United States, Australia, New Zealand, Belgium and France. The research method uses the Import Dependency Ratio (IDR) method to analyze the level of dependence of Indonesia's imports on imported

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.
