Abstrak: Good farming practice (GFP) is a guidline for good beef cattle raising in order to improve the existing cattle fattening operation. The scope of GFP in beef cattle farming includes four aspects: facilities, production processes, environmental protection and supervision. PT Lembu Jantan Perkasa is one of beef cattle company engaged in breeding, fattening and cattle trading. The application of GFP becomes very important for these companies to produce environmentally freindly beef cattle with high productivity. In general PT Lembu Jantan Perkasa has a play well four aspect: facilities, production processes, environmental protection and supervision. As a results the beef cattle has performance very well in feedlot as indicated by high daily gain: steer 1,67 kg/day, bull 1,48 kg/day, heifer 1,36 kg/day in 2010. These were several aspect need to be consider in order to improve the implementation GFP. Those include: site plant building and biosecurity.

Judul: Penerapan good breeding practices sapi potong di PT lembu jantan perkasa Serang-Banten
Abstrak: Cow-calf production is fundamental to the other cattle production system, i.e growing of stocker and cattle finishing. Good Breeding Practices (GBP) for beef cattle is important for breeding goal achievement that is producing breeding animal. The scope of GBP in beef cattle farming includes four aspects: facilities, cattle breeding, environmental protection and supervision. The study aimed to examine the Good Breeding Practices for beef cattle at PT Lembu Jantan Perkasa (LJP) in Serang -Banten. Descriptive analysis was used to review the breeding operation in PT LJP Serang-Banten. The breeding parameters observed were calving interval, service per conception, conception rate, and calving rate. The result showed that in general the company had applied well GBP in its operation. There were several aspects that should be considered to improve the GBP operation those site plant building and security, replacement stock, and animal health. Calving interval are 408 days in 2009 and 372 days in 2010. Service per conception are 1,6 in 2009 and 1,5 in 2010. Conception rate are 78% in 2009 and 88% in 2010 and calving rate are 23% in 2009 and 84% in 2010.

Judul: Heisenberg Uncertainty of Double SlitSystem Based on Budiyono-Rohrlich Quantum Statistics Model
Abstrak: Interpretasi kuantum dikembangkan untuk memaknai secara fisis dengan jelas bagaimana suatu dinamika pada sistem mikroskopis yang dijelaskan dengan teori-teori kuantum, seperti interpretasi Copenhagen yang mendeskripsikan sistem kuantum sebagai suatu keadaan yang dideskripsikan dengan fungsi gelombang yang berisikan bagaimana peluang keadaan suatu sistem. Interpretasi kuantum juga bisa dibawa dari suatu sistem klasik seperti pada model statistika-kuantum Budiyono-Rohrlich yang menjelaskan bagaimana dinamika kuantum berhubungan dengan sistem klasik dengan penerapan statistika pada model Hamiltonian sistem. Fungsi distribusi dapat mendeskripsikan bagaimana suatu sistem terdistribusi pada suatu ruang pada pandangan klasik namun untuk sistem kuantum fungsi distribusi adalah peluang dari sistem tersebut. Sistem klasik dan kuantum juga dipisahkan berdasarkan pada ketidakpastian Heisenberg tentang suatu pengukuran yang tidak bisa secara sekaligus dilakukan bersamaan. Model statistika-kuantum Budiyono-Rohrlich membawa suatu sistem klasik menjadi sistem kuantum dengan dua aksioma yaitu hukum kekekalan energi rata rata dan konservasi rapat probabilitas. Sistem klasik yang didefinisikan akan diatur dengan menambahkan dua variable matematis berupa ontic extensions dan epistemic restrictions dimana kedua variabel ini yang akan menghubungkan bagaimana sistem klasik bisa diubah menjadi sebuah sistem kuantum. Dua variabel matematis tadi membuat sebuah sistem bisa diperlihatkan ketidakpastiannya lewat perhitungan simpangan rata-rata dan hasilnya akan selalu memenuhi ketidakpastian Heisenberg
