Judul: Performa Produksi Dan Karakteristik Organ Dalam Ayam Kampung Umur 12-16 Minggu Yang Diinfeksi Cacing Ascaridia galli  Dan Disuplementasi Ekstrak Daun Jarak Pagar (Jatropha curcas Linn)
Abstrak: J. curcas leaf contains some active substances such as flavonoid, saponin, steroid, phenol hidroquinon, triterpenoid and alkaloid which have a potential role as natural anthelmintics to replace synthetic anthelmintic for poultry. This study was carried out to investigate the effect of J. curcas Linn leaves extract and albendazole on performances and internal organs percentage of kampong chickens aged 12-16 weeks. The chickens kept in cage system during 28 days. A completely randomized design (CRD) with four treatments and four replications was used in this experiment. The treatments were : Basal diet (R1), Basal diet + 5% J. curcas Linn leaves extract in water (R2), Basal diet + 10% J. curcas Linn leaves extract in water (R3), and Basal diet + 1% albendazole in water (R4). The parameters observed were performances (feed consumption, final body weight, body weight gain and feed conversion) and internal organs percentage (liver, heart, gizzard, kidney, spleen, intestines, length of intestines and relative length of intestines). Data were analyzed using analysis of variance. The treatment effects were further analyzed using Duncan multiple range test. The results showed that supplementation of J. curcas Linn leaves extract and albendazole did not affect the feed consumption, feed conversion, body weight gain and internal organ percentage. However, supplementation of albendazole decreased (p<0.05) the small intestine percentage. It is concluded that supplementation of J. curcas Linn leaves extract up to 10% was not effective as albendazole to increase body weight gain.

Judul: Performa Ayam Kampung yang Diberi Campuran Pakan Berupa Dedak Padi dan Daun Singkong (Manihot esculenta Crantz
Abstrak: Kampung chicken is often cultivated in Indonesia in semi-intensive and extensive. This chicken has slower growth than broiler. A four weeks kampung chicken old has weight 0.20 kg while broiler has weight 1.2 kg, but kampung chicken could digest crude fiber more than 5% of the nutrient content of the feed. Rice and cassava are widely grown in lowland as well as highland and their residual processing can be used as feed. The purpose of this study was to investigate the performance of kampung chicken fed rice bran and cassava leaves. Rice bran and dried cassava leaves were stirred in warm water before feeding to the chickens. Treatment feed was given to the chickens aged 5-12 weeks (P2) and 8-12 weeks (P3) in pasta form. The control (P1) was given commercial feed at the age of 0-12 weeks. The analysis showed the feeding method influences the body weight of kampung chicken. The highest body weight showed in P1 with lowest feed conversion. The lowest body weight showed in P2 with highest feed conversion. Treatment P3 resulted body weight and feed conversion between P1 and P2. The highest mortality (13.33%) showed in P2. Rice bran and cassava leaves were good to give to kampung chicken in 9 weeks to replace commercial feed.

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
