Judul: Ukuran Tubuh Ayam Kampung yang Diberi Pakan Dedak Padi dan Daun Singkong (Manihot esculenta Crantz)
Abstrak: This study aimed to know body size of native chicken with a fed mixture of rice bran and cassava leaf as long 12 weeks. Animals used native chicken as much as 45 males and 45 females. The feed is commercial feed (P1), a mixture of 75% rice bran and 25% cassava leaves as a substitute for commercial feed given from the age of 5-12 weeks (P2) and the age of 9-12 weeks (P3). These research used a randomized complete design (RCD) 2x3 factorial with 3 repetition. The first factor was sex (male and female). The second factor was the type of feed (P1, P2 and P3). Data was analyzed of variance (ANOVA). The variables measured were body weight, wing length, length of spine, sternum length, length of femur, tibia length, shank length, chest circumference and shank circumference. The results showed no interaction between sex with feed treatment toward of body size. Feed affected the morphometric of native chicken. Feed P2 given the lowest performance for all body size variables and impaired growth of native chicken when given from the age of 5-12 weeks. Feed rice bran mixture 75% and 25% cassava leaf can be given from the age of 8 weeks.

Judul: Potongan Komersial Ayam Kampung dengan Pemberian Pakan Dedak Padi dan Daun Singkong (Manihot esculenta Crantz)
Abstrak: In this research, kampung chicken was fed with rice bran and cassava (Manihot esculenta Crantz) leaf as alternative feed. This research investigated the effect of feeding rice bran and cassava leaf to percentage of carcass and commercial cuts of twelve weeks old kampung chicken. The chickens were fed by commercial feed 100% (P), by rice bran 75% and cassava leaf 25% from 5th- 12th weeks (Q), and by rice bran 75% and cassava leaf 25% from 8th-12th weeks (R). This research was factorial completely randomized designed (RAL) with 2x3 pattern. Data was variant analyzed (ANOVA). The analysis showed the feeding method influence the percentage of carcass and commercial cuts of kampung chicken. The highest pencentage showed in P treatment whereas the lowest in Q treatment. Feeding by rice bran and cassava (Manihot esculenta Crantz) leaf began 5th weeks showed decreasing percentage of carcass and commercial cuts of kampung chicken. Rice bran and cassava leaf can be fed to 8-12 weeks old chicken resulting of 0.7-0.9 kg body weight and also showed the percentage of commercial cuts same as fed by 100% commercial feed (P) except wing parts (P<R).

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
