Abstrak: Several tough questions that are still hotly debated on cattle fattening industry are the government interference in case of self-sufficiency policies or release beef market to market mechanism and the profitability of cattle fattening and slaughter houses business in Indonesia. The answers of those questions have strong implications for players, investor and the government itself. Its implications are the chance of small-cattle farmers, the risk that may be faced by feedlot companies, consumers loss or advantage and competitive position on free trade era. The government should set out a clear strategy towards free trade era. The increase of imported beef and feeder cattle is a highlight concern about Indonesian cattle fattening industry competitiveness. The objectives of this study were to analyse market mechanism i.e. supply and demand, players, investment and to conduct environmental assessment including field research to evaluate strengths, weaknesses, opportunities and threats on cattle fattening and slaughter houses business in Indonesia. The results were then used to examine strategies and business implications to develop and to improve cattle fattening and slaughter houses business in Indonesia that may be useful for government and business practitioners. Market mechanism was analysed following the econometric method to build a model of beef cattle market in Indonesia. Survey was also conducted at PT Tippindo, PT INKUD Satwa Nusantara and PT Great Giant Livestock Co. For completing reliable data, actual information was also collected from key magazines, journals and news papers. SWOT Matrix was used to conduct environmental assessment .......

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: Konstruksi aritmetika kurva eliptik F(2m) supersingular dan non-supersingular untuk skema kunci publik ElGamal
Abstrak: Algoritme ElGamal adalah salah satu algoritme kunci publik dengan aritmetik modular p yang mempunyai struktur grip siklik Z(p). Tingkat keanaman algoritme ini terletak pada pemecahan masalah logaritme diskret dari Z(p). Akan tetapi, tingkat keamanan tadi tahun ke tahun semakin menurun yang disebabkan kemampuan pemecahan algoritme diskret semakin meningkat. Untuk memenuhi tingkat keamanan yang memadai dibutuhkan p yang cukup besar yang menyebabkan proses enkripsi dan dekripsi menjadi lambat.
