Judul: Integrasi Pasar dan Respon Penawaran Daging Sapi di Indonesia
Abstrak: Indonesia's beef needs are met from three sources, namely local beef, imported cattle and beef imports. This is because local beef production in 2013 amounted to 545 600 tonnes, while beef consumption reached 757 088 tonnes. This leads to the presence of excess demand in order to meet the needs of domestic beef and veal imports carried out beef. In order to increase the availability of beef in Indonesia, there are still some problems which are beef production centers in Indonesia are still concentrated in a few regions such as East Java and NTB, while regional consumption centers are in Greater Jakarta. The second problem is the liberalization of the beef market, where custom duties beef from abroad will be lower than previous implications on the price of imported beef to be much cheaper and the price of local beef that follow the movement of the price of beef imports also become cheaper than ever, this leads to fluctuations in the price of beef in the domestic market to fully follow the market mechanism. In addition, there are other issues that beef production is still low. Beef cattle farm productivity is still low and caused by the majority of livestock breeders in Indonesia that is dominated by people who are still subsistence so that the average farmer in Indonesia responded less to changes in the price of beef at this time continues to increase. The purposes of this study were to: (1) analyze the integration of the beef market center's cut in some provinces and other provinces in Indonesia, (2) analyze the integration of the domestic beef market in Indonesia with the world's beef market, (3) analyze the response to the breeder supply's changes in the price of beef in Indonesia. This research used the model VECM (Vector Error Correction Model) to analyze the integration of the beef market and used the model ECM (Error Correction Model) to analyze the supply response of beef. The data used were the time series data (time series) in the months (January 2009 to December 2013) and the data quarterly (first quarter 2001 to fourth quarter 2013). Data obtained from several agencies such as the Central Statistics Agency (BPS), Bank of Indonesia, Directorate General of Livestock and Animal Health and the Ministry of Trade. The results showed that there was co-integration (integration in the long term) between beef production areas (East Java and NTB) with consumption centers (Jakarta and West Java), but the integration did not occur, and which was the market for commodity beef could not be treated as a single market and changes in the market price of beef production center which was not necessarily the same impact on the change in the price of beef in beef consumption centers. This was also confirmed by the results of the Granger causality test which showed that prices in central areas of consumption were not necessarily affecting the beef prices in central areas of consumption, and vice versa. Therefore, the response rates from central areas to the consumption of beef production areas still were unidirectional. This

Judul: Analysis of  the  factors that affect  the  price  of  beef in Indonesia
Abstrak: Dalam rangka mewujudkan kecukupan daging sapi di dalam negeri maka pemerintah Indonesia mencanangkan program swasembada daging sapi. Konsep swasembada tersebut tidak hanya menyangkut ketersediaan tetapi juga akses masyarakat terhadap pangan itu sendiri. Akses masyarakat terhadap daging sapi dapat dilihat dari harga komoditas tersebut. Harga daging sapi di Indonesia relatif lebih tinggi dibandingkan dengan negara lainnya. Hal ini menyebabkan daya beli masyarakat terhadap daging sapi menjadi rendah. Disamping itu, kondisi harga yang tinggi kenyataannya juga tidak dapat menjadi insentif bagi peternak untuk meningkatkan produksi daging sapi. Mengingat permasalahan tersebut, harga daging sapi menjadi hal penting untuk dikaji lebih lanjut sehingga perlu dianalisis faktor-faktor yang mempengaruhi harga daging sapi di Indonesia. Data yang digunakan adalah data time series tahun 2008-2013. Analisis deskriptif dan model persamaan regresi linear berganda digunakan sebagai alat analisis dalam penelitian ini. Hasilnya berdasarkan analisis deskriptif harga daging sapi di Indonesia dipengaruhi oleh jalur distribusi yang panjang sedangkan berdasarkan model persamaan regeresi linear berganda terdapat tiga variabel yang berpengaruh yaitu harga daging sapi periode sebelumnya, hari raya lebaran (Idul Fitri) dan impor daging sapi., To reduce dependence on beef import, Indonesian government declared an increase of beef production by Self Sufficiency Program 2014. The meaning of self sufficiency in this case is not only about its availability but also public access to food itself. Public access to the beef can be seen from its price. The price of beef in Indonesia is relatively high compared to other countries. This condition caused public purchasing power on beef to be low. In addition, the high price could not be an incentive for breeders to increase beef production. Based on this problem, this research aim to analyze the factors that affect the price of beef in Indonesia. This research used time series data form in period 2008 to 2013. As a result, based on descriptive analysis the price of beef in Indonesia is affected by its distribution chain. On the other side, based on multiple linear regression model there are three variables that affect the price of beef in Indonesia such as the price of beef earlier periode, Eid celebration, and volume of beef import.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
