Abstrak: The purpose of this experiment was to study the ability of mulberry leave meal addition on concentrates on the digestibility of nutrient and performance of Ongole Grade. This experiment used a randomized block design, with 4 treatments and 4 blocks. Treatments consisted of P1 (native grass and concentrate feed in the form of mulberry leaves meal and concentrate complete), P2 (native grass and concentrate feed in the form of mulberry leaves meal and corn concentrate), P3 (native grass and concentrate feed in the form of mulberry leaves meal and rice bran concentrate), P4 (native grass and concentrate feed in the form of mulberry leaves meal and concentrate tapioca waste). The experiment was conducted for 4 months with the adaptation periods for 2 weeks. Parameters measured were feed consumption, daily body weight gain, feed efficiency, Income Over Feed Cost (IOFC), revenue cost ratio, nutrient digesbility, nitrogen retention, VFA, NH3 and allantoin urine. The results showed that the mulberry leave meal addition on different concentrate did not significantly (P>0.05) affect daily body weight gain, feed consumption, feed efficiency and Income Over Feed Cost (IOFC), but significantly on digestibility of dry matter and organic matter (P<0.05). It is concluded that based on the nutrient digestibility, mulberry leave meal concentrate can be combined with a single concentrate such as corn, cassava waste meal or complete concentrate .

Judul: Kecernaan Ransum Berbasis Jerami  Padi yang Diberi Tepung Daun Murbei  Sebagai Substitusi Konsentrat Pada  Sapi Peranakan Ongole
Abstrak: Mulberry leaf has a great potential as animal feed because of its high nutrient content. It has 20,4% crude protein, therefore it can be used as substitution for concentrate. The aims of this experience was to study effect of mulberry leaf as substitution of concentrate in PO cattle. This experiment used completely randomize design with 3 treatments and 4 replications. The treatments were P1 (50% rice straw + 50% concentrate/control), P2 (50% rice straw + 25% concentrate+ 25% mulberry leaf), P3 (50% rice straw + 50% mulberry leaf). This experiment was conducted for 2 months with 2 weeks adaptation periode. Variables observed were dry matter digestibility, crude protein digestibility, crude fiber digestibility, extract eter digestibility, and total production of rumen VFA. The data were analyzed by Analysis of Variance, and differences among treatments were tested with Duncan Multiple Range Test. The results showed that mulberry leaf can substitute concentrate at most 50%. The addition of mulberry leaf significantly (P<0.05) increased crude fiber digestibility but decreased crude protein and eter extract digestibility. The mixture between concentrate and mulberry leaf increased dry matter digestibility and the amount of total VFA.

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
