Judul: The Physical Characteristic of Market Vegetable Waste Wafer and that Palatability for Sheep Livestock
Abstrak: Limbah sayuran adalah bagian dari sayuran atau sayuran yang sudah tidak digunakan atau banyak ditemukan di pasar-pasar sayuran. Kelemahan limbah sayuran pasar antara lain adalah mudah busuk, voluminous (bulky) dan ketersediaannya berfluktuasi sehingga diperlukan teknologi pengolahan pakan untuk membuat bahan menjadi tahan lama, mudah disimpan dan diberikan pada ternak. Salah satu cara untuk mengatasi hal tersebut adalah pembuatan wafer hijauan. Penelitian ini bertujuan untuk mengetahui sifat fisik dan palatabilitas wafer limbah sayuran pasar yang akan diberikan pada ternak domba.

Judul: Uji Sifat Fisik Wafer Limbah Sayuran Pasar dan Palatabilitasnya pada Ternak Domba
Abstrak: Vegetable waste is part of vegetables or vegetables that are discarded. The weakness of this vegetable market waste, among others, is perishable, voluminous (bulky) and the availability was fluctuated so the processing technology is needed to make this vegetable waste to be durable, easy to stored and to be given to dorbia. To solve this problem vegetable waste could be formed as wafer. The objective of this experiment was to determine the physical characteristic and palatability of vegetable market waste after formed as a wafer. The experimental design used in this research was Completely Randomized Design with 5 treatments and 4 replications. The treatments were : R1: maize straw 100%; R2: maize straw 75% + mungbeans sprout waste 25%; R3: maize straw 50% + mungbeans sprout waste 25% + cauliflowers 25%; R4: maize straw 25% + mungbeans sprout waste 50% + cauliflowers 25%; R5: maize straw 25% + mungbeans sprout waste 25% + cauliflowers 50%. Wafer’s variables measured were water activity, water absorption, density and palatability. The results of this research indicated that the treatment of wafer made from vegetable waste gave significant effect to the water activity (P<0.08) and wafer palatability (P<0.05). The highly significant effect (P<0.01) were from on water absorption and wafer density. Based on physical characteristic result of market vegetable waste wafer R1 have the highest water absorption. Wafer R5 gave a lowest water activity and wafer R3 gave a highest wafer density. The ration R4 was the most palatable compare to other treatments for the experimental sheep.

Judul: Dinamika Infeksi Virus HIV dengan Terapi Reserve Transciptase Inhibitor CRT Inhibitor)
Abstrak: Acquired immunodeficiency syndrom (AIDS) is a disease in the human system caused by the human immunodeficiency virus (HIV). In general, HIV virus is transmitted through direct contact with a body fluid containing HIV virus, such as blood transfusion or free sex. The major target of HIV virus infection is white blood cells. Although some therapies for AIDS can reduce the spreading of the disease, there is currently no vaccine or cure. The most effective therapy is antiretroviral therapy. Antiretoviral therapy consist of three therapies, i. e. reserve transcriptase inhibitor, protease inhibitor and a combination of both therapies. The objective of this paper is to determine the influence of reserve transcriptase inhibitor therapy to the dynamics of HI V virus infection in blood. This dynamics can be formulated in some mathematical models, i. e. the model of perfect RT inhibitor therapy and the model of imperfect RT inhibitor therapy. Furthermore, the dynamics of the virus infection can be shown in a basic reproduction number. If this number is less than one, then the virus population will be vanished. On the other hand, if it is larger than one, then the virus population will remain in blood.
