Judul: Desain Camilan Puffed Rice Cakes dengan Penambahan Buah Kering (Dried Fruits) dan Biji Wijen (Sesamum orientalis L.) sebagai Camilan Sehat untuk Anak-anak
Abstrak: Puffed rice cakes are whole grain products that recommended for childrens because they are low in fat and calories, high in fiber, protein, and calcium. They are made from a combination of puffed rice, glucose syrup, fructose, dried fruits (mango) and sesame seeds in percentages of 8 : 4 : 1 : 4 : 4, using a Universal Testing Machine (UTM). UTM is an equipment that is used for testing a compression and tensile test. In this research, UTM applied various combination loads to the puffed rice cakes. This method created various puffed rice cakes with different thickness. This different thickness was caused by the different combination of loads from UTM, they are 0.5 kN, 1 kN, 2.5 kN and 5 kN. The effects of having various combination load bears a significant impact upon their structure or density of puffed rice cakes. The parameters were observed to see the quality of the product which include physical properties (dimensions, density, appearance and thickness) and organoleptic value (appearance, taste, texture, acceptance, thickness, and crispiness). The result shows that the hardness of puffed rice cakes became higher for the higher load of pressure used in puffed rice cakes production, and the organoleptic value become lower especially taste, texture and acceptance. It is therefore conclude that optimum load used in puffed rice cakes process is 1 kN.

Judul: Aplikasi Puffing Gun dan Metode Ayakan Getar (Vibrating Mesh) Dalam Proses Pembuatan Berondong Beras dan Berondong Ketan Butiran Berlapis Gula
Abstrak: Puffing rice and puffed glutinous rice are the traditional snack commonly available in the market. The objectives of this research are, first, to determine the puffing time when using a puffing gun to puff the rice/glutinous rice grains. Second, to know the effect of moisture content of the grains to the physical properties of puffed rice and puffed glutinous rice. The next objective is to design a product of sugar coated puffed rice and puffed glutinous rice granules. The materials used were rice and glutinous rice and were conditioned to the moisture content of 14, 16, 18, and 20% wb. The quality parameters used were water losses, hardness, specific volume, and an organoleptic test for the preference. Puffed rice which has been puffed using the puffing gun then were coated with melted of sugar granules in a ratio of 1:1 (w/w), and then were vibrated using a vibrating mesh with 80 mm, 90 mm, and 100 mm amplitude. This process is carried out for 5 minutes, 10 minutes, and 15 minutes. Results show that the moisture content the rice/glutinous rice grains significantly affect the puffing time, water losses, hardness, specific volume, and even the organoleptic preferences of the puffed rice/glutinous rice. Glutinous rice grain with 14% moisture content is the most preferred in terms of flavor, crispy, color, specific volume, texture, and taste. Vibration using amplitude 90 mm in 15 minutes is successfully can be used to produce sugar coated puffed rice granules.

Judul: Pengaruh Infeksi Haemoproteus columbae (Kruse, 1890) Pada Burung Merpati Dan Cara Penanggulangannya
Abstrak: Haemoproteus columbae merupakan paras it yang menyerang sel-sel darah merah burung rnerpati. Siklus hidupnya kompleks dan dapat dibagi menjadi dua yaitu siklus hidup asexual terjadi delam tubuh burung merpati dan siklus hidup sexual terjadi dalam tubuh lalat dari famili Hippoboscidae sebagai vektor. Stadium yang nampak dalam peredaran darah perifer hanyalah garoetosit yang dapat dibedakan menjadi dua yaitu gametosit jantan (mikrogametosit) dan gametosit betina (makrogametosit).
