Competitiveness of layer business was determined by the level of efficiency, which was influenced by the level of technology adoption, production costs, and economy of scale. This study was carried out from April to July aim to analyse the performance of small-scale layer poultry farming. The study site was in the layer production centre, namely in Payakumbuh West Sumatera, Blitar East Java and Sidrap South Sulawesi. Primary data were collected through interviews with 50 farmers and 12 poultry shops at all study sites. Analysis of the efficiency level is using DEA (Data Envelopment Analysis) software and business feasibility using financial analysis. The following were the main research findings: (1) the development of layer farming technology had not been responded well by farmers so that the production level and mortality of chickens were still below standard; (2) relatively, the level of layer poultry farming efficiency in Sidrap and Payakumbuh was better than in Blitar with a value closer to one, where the inefficiency was due to the use of excessive inputs; and (3) small-scale layer poultry farming was financially feasible, where the determining factors were feed and eggs price. The study recommended the need to add both technical service staff from poultry shops and local agricultural extension workers. Feed costs should be reduced by IDR 1,000 in Blitar and IDR 57 di Sidrap per kilogram of eggs produced per period. In addition, an accurate and better allocation of corn for feed was needed to optimise the ratio of feed and egg price optimal.
Abstract:Elliptic Curve Cryptography is generally are implemented over prime fields or binary fields. Arithmetic in binary fields can be classified according to the basis representation being used. Two of the most common basis used in binary fields are polynomial basis and normal basis. The optimal normal basis is especially known to be more efficient than polynomial basis because the inversion can be achieved by performing repeated multiplication using the method of Itoh and Tsujii, and squaring can be executed by performing only one cyclic shift operation. In previous research we have built algorithms and implementations on basis conversion between polynomial basis and normal basis. In this paper we will present implementation of arithmetic operation algorithms on both polynomial basis and optimal normal basis representation and the conversion method between them. We will also give comparison of time and space between implementation by using optimal basis representation with conversion and without conversion.
Semakin banyaknya penggunaan aplikasi jaringankomputer antar kantor cabang, akan memudahkan organisasidengan banyak kantor cabang untuk berkolaborasi, namun tidaksemua aplikasi bisa di lewatkan jalur internet, denganmempertimbangkan aspek keamanan atau memang akibatketerbatasan dari aplikasi itu sendiri. Untuk itulah digunakanmetode EoIP untuk menghubungkan dua atau lebih kantor suatuorganisasi dengan biaya relatif lebih murah dari sewa VPN-IP,dengan memanfaatkan jaringan ADSL (public network/internet).Fitur ini akan membridge jaringan antar kantor cabang denganmelewati jaringan publik (internet).
