Judul: Analisis usahatani terpadu pada Anugrah Farm di Kecamatan Tajur Halang Kabupaten Bogor
Abstrak: Integrated farming system is a business system that combines the components of agriculture, such as plants, animals and fish in a union. Longyam is one of the integrated farming system concept that combine the maintenance between fish and poultry. The purpose of this research was; 1) to analyze the effect of integrated farming system to the cost structure, revenue, additional benefits, income, and contribution of Anugrah Farm businesses, also 2) to analyze the efficiency level of Anugrah Farm‟s businesses. This research used farm income analysis method that include cost, revenue, and the business efficiency level analysis. Research shows that cost and revenue from chicken poultry method is higher than other businesses. An additional benefit of integrated farming was received cost saving and chicken feses transfer price. In business contribution, chicken poultry business is more contribute than catfish business to longyam‟s revenue. Chicken poultry business is more efficient to develop, with the value of R/C ratio is higher than other businesses.

Judul: Analisis kelyakan usaha sistem pertanian terpadu di AD Farm di Kecamatan Leuwisadeng Kabupaten Bogor
Abstrak: Sistem pertanian terpadu merupakan konsep pertanian yang menerapkan pengolahan limbah sehingga dapat digunakan kembali. Konsep pertanian terpadu dapat mengoptimalkan seluruh sumberdaya yang ada, sehingga limbah yang dihasilkan dapat memberi tambahan manfaat bagi usaha yang dijalankan. Salah satu usaha yang menerapkan konsep pertanian terpadu adalah AD Farm. Komoditi utama yang dihasilkan oleh AD Farm adalah Cabai, Jagung, Pepaya Calina, Jambu Kristal, Ayam Broiler dan Domba. Selain komoditi utama juga terdapat komoditi sampingan yang dihasilkan oleh AD Farm yaitu Babycorn, Pupuk kandang dan Kompos. Tujuan dari penelitian ini yaitu menganalisis struktur biaya usahatani, nilai penerimaan, pendapatan, rasio R/C dan usahatani dengan menerapkan sistem pertanian terpadu. Metode analisis yang digunakan adalah analisis pendapatan usahatani dan R/C Rasio. Hasil penelitian menunjukkan dengan mengadopsi sistem pertanian terpadu AD Farm dapat mengurangi biaya untuk pembelian pupuk. Selain itu dengan menerapkan sistem pertanian terpadu AD Farm dapat mengurangi jumlah buah yang rusak karena lalat buah pada komoditi Jambu Kristal dan Pepaya Calina dan menyebabkan penerimaan meningkat. Sehingga dapat dinyatakan dengan menerapkan sistem pertanian terpadu AD Farm dapat memperoleh peningkatan keuntungan.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
