Judul: EVALUATION OF PRODUCTION AND QUALITY OF PASTURE AT BPTU-HPT PADANG UPGRADING BASED ON PLANTING PATTERN
Abstrak: Padang penggembalaan dapat menjadi salah satu sumber lahan diperolehnya pakan utama bagi ternak. Pengembangan padang penggembalaan sebagai sumber pakan utama ternak dapat dilakukan dengan cara membedakan pola tanam pada vegetasi utamanya. Penelitian ini bertujuan mengevaluasi tingkat produksi dan kualitas padang penggembalaan berdasarkan pola tanam di BPTU-HPT Padang Mengatas. Penelitian ini menggunakan metode observasi lapang secara langsung. Penelitian ini dianalisis menggunakan T-test paired sample pada 2 pola tanam berbeda dengan 4 ulangan (Pedok yang berbeda). Peubah yang diamati adalah karakteristik warna dan pH tanah, jenis hijauan, analisis vegetasi hijauan dan potensi lahan (produksi hijauan, kapasitas tampung, pasture condition scoring). Hasil penelitian menunjukan bahwa pada pola tanam monokultur dan polikultur tidak berbeda nyata terhadap semua peubahnya. Simpulan penelitian meliputi kualitas dan produksi hijauan di BPTU-HPT Padang Mengatas tergolong tinggi, dengan kapasitas tampung dan produksi hijauan adalah 3026,40 Kg Ha-1 dan 4,86 ST Ha-1 Tahun-1 pada pola tanam monokultur, 3278,12 Kg Ha-1 dan 5,26 ST Ha-1 Tahun-1 pada pola tanam polikultur. Kualitas padang penggembalaan antara pola tanam monokultur dan pola tanam polikultur berdasarkan indeks dominansi, analisis keragaman, pH dan warna tanah memiliki nilai yang sama., Grazing fields can be one of the main sources of land obtained for livestock. The development of grazing fields as the main source of animal feed can be done by distinguishing planting patterns on the main vegetation. This study aims to evaluate the production rate and quality of pasture based on planting patterns in BPTUHPT Padang Mengatas. This study uses field observation method directly. This study was analyzed using T-test paired samples on 2 planting patterns (Monoculture and Polyculture) in contrast to 4 different tests (Paddock). The observed changes are the characteristics of soil color and pH, forage type, forage vegetation analysis and land potential (forage production, capacity, pasture condition scoring). The results showed that monoculture and polyculture planting patterns are no different from all the changes. The conclusion of the research includes the quality and production of forage in BPTUHPT Padang Mengatas is relatively high, with the capacity of capacity and forage production is 3026.40 Kg Ha-1 and 4,86 ST Ha-1 Year-1 in monoculture planting patterns, 3278.12 Kg Ha-1 and 5,26 ST Ha-1 Year-1 on polyculture planting patterns. The quality of grazing fields between monoculture planting patterns and polyculture planting patterns based on dominance index, diversity analysis, pH and soil color have the same value.

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.
