Abstrak: Inner part of cassava peel is one of agriculture by product that can use as alternative feed in farm. Cassava peel has anti nutrition that called HCN, which limited factor to utilization. Feed is one of factor that influence meat quality, therefore it contents should be understand that is nutrition or anti nutrition. Physical properties of meat are important factor which determined in meat quality. This research was conducted to observed physical properties of thin tailed ram sheep’s meat which gave forage (Brachiaria humidicola) and cassava peel by differ level. This research used twelve thin tailed rams sheep under one year old with average body weight 19.06 ± 1.46 kg. The dietary treatments divided in four differ level of forage and cassava peel, included: 100% Brachiaria humidicola, 80% Brachiaria humidicola with 20% cassava peel, 60% Brachiaria humidicola with 40% cassava peel and 40% Brachiaria humidicola with 60% cassava peel. The variable observed tenderness, cooking loss, water holding capacity and pH value. The experiment design was randomize complete block design and the data analyzed by analysis of variance (ANOVA). The results showed that the experiment treatments have not significant effects (P>0.05). It concluded that cassava peel is able to be utilized as combination with Brachiaria humidicola up to 60% in level of ransom for sheep and it not influence meat quality by physical properties.

Abstrak: The body condition of livestock is affected by physiological process which is stimulated by environmental changes such as weather, nutrition and management factors. The main objective of this research is to observe physiological response of male indigenous local sheep given different level of Brachiaria humidicola grass and cassava hull. Twelve yearling male indigenous local sheep with initial average body weight 19,06 ± 1,46 kg were used in this research. Dietary treatments consisted of R0: 100% Brachiaria humidicola + 0% cassava hull, R1 : 80% Brachiaria humidicola + 20% cassava hull, R2: 60% Brachiaria humidicola + 40% cassava hull, R3: 40% Brachiaria humidicola + 60% cassava hull. The parameters observed were rectal temperature, frequency of respiration, and heartbeat. Both indoor and outdoor microclimate had been measured (temperature and humidity). Randomized Complete Design with three repetition was used to analyze the data, and any significant differences were further tested by using Duncan’s test. The experimental showed that result were not significant (P>0,05) to rectal temperature, frequency of respiration and heartbeat. It is concluded that the use of cassava hull in feed must be more carefully because of HCN as limited factor and its possible negative effect on sheep physiology response.

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
