Judul: Rancangan Kemasan Karton Bergelombang dengan Bahan Pengisi untuk Transportasi Jagung Semi (Baby corn)
Abstrak: Baby corn packaging usually use crate during transportation whereas it could make mechanical damages to the product like scratch, bruised, broke, and ripen rapidly. The purpose of this research was to design a proper packaging using carton material and filled material that could maintain the quality of baby corn during the transportation. In this research, C flute and BC flute, that has dimension (31x23x9)cm, (46.5x23.5x9)cm, (32x24x10)cm, (47.5x24.5x10)cm, were used as the outer packaging, B flute as inner, PE plastic as primary packaging, and pieces of paper as filling material. K4C and K6C were selected because those more adaptable in cold storage, those has good compression strength, and lower cost. Transportation conversion simulation result during two hours is similar to 169.553 km out of town length or 2.83 hours with 60 km/hour speed. Mechanical damage of the K4C is 17% meanwhile the K6C 15.9%, this is caused by the pieces of paper which used as the filling material around the product. The treatment of packaging directly influent to the parameter reduced of weight, hardness, and total dissolved solids of baby corn. On the other hand, the treatment of packaging indirectly influent the water content in the baby corn.

Judul: Pengaruh Kemasan Terhadap Mutu Fisik Baby Corn (Zea mays L.) Selama Simulasi Transportasi
Abstrak: Distribution of baby corn from farmers to distributors in the market is generally transported using polyethylene plastic (25 kg/pack) with less consideration of its quality during the transportation. This condition causes baby corn often suffer from physical damages, such as broken and cracked. The purpose of this research was to study the influences of packaging materials on the mechanical damage and physical properties of baby corn during simulated transportation with addition of 8 days storage. Within this study, packaging materials chosen (considered as treatments) were: (i) combination between crates and polyethylene plastic, (ii) cardboard and polyethylene plastic, (iii) solely crates, and (iv) cardboard. Simulation was carried out at 2 hours transportation. The use of polyethylene plastic is capable of pressed the mechanical damage and reduced weight. The quantified physical parameters were mechanical damage, reduced weight, hardness, total dissolved solids and moisture content. Therefore, based on the reduced weight test and in combination with analysis of variance, the suitable packaging material for transporting baby corn was the one which combined from cardboard and polyethylene plastic.

Judul: Infeksi leucocytozzon simondi (Mathis dan Leger, 1910) pada itik
Abstrak: Leucocytozoonosis pada itik adalah penyakit protozoer yang disebabkan oleh parasit darah Leucocytozoon simondi. Protozoa ini ditularkan oleh lalat penghisap darah (Simulium sp.). Di dalam tubuh induk semang antara (vektor) Simulium parasit mengalami tahap gametogoni yang kedua (pembentukan gamet dan pembuahan) dan sporogoni. Pembuahan makrogamet oleh mikrogamet terjadi segera sesudah vektor menghisap darah itik yang mengandung gametosit. Pembuahan menghasilkan zigot yang dapat bergerak (ookinet) yang masuk dinding usus vektor dan kemudian memasuki tahap sporogoni. Tahap sporogoni memerlukan waktu kira-kira 1 minggu (Fallis dan Desser, 1977) untuk menghasilkan sporozoit. Sporozoit bergerak menuju kelenjar ludah vektor, tempat mereka berkumpul. Sporozoit dipindahkan ke dalam tubuh itik pada saat vektor menghisap darah itik. Di dalam tubuh itik, parasit mengalami tahap skizogoni dan tahap gametogoni yang pertama (pembentukan gametosit). Sporozoit memasuki peredaran darah itik dan memasuki sel-sel parenkhim hati membentuk skizon hepatik (Fallis et al., 1974). Setelah 4 6 hari, skizon hepatik dewasa menghasilkan merozoit dan sinsitia. Merozoit dari skizon hepatik memasuki eritrosit dan eritroblas membentuk gametosit bundar, sedangkan sinsitia memasuki sel-sel RES di seluruh tubuh membentuk megaloskizon. Megaloskizon dewasa terbentuk dalam waktu 5 hari di dalam sel-sel itu dan menghasilkan merozoit. Merozoit dari megaloskizon memasuki limfosit dan leukosit lainnya membentuk gametosit memanjang. ...
