Abstrak: Harvesting activity are one of the important activities in the palm oil production process. Harvesting activity consist of cutting fresh fruit bunches (FFB) from their stems, collection, and transport. Transportation activities in the process of collecting FFB still using simple tools, it’s wheelbarrow driven by humans. Collection FFB activity is one tough job and requires large manpower. The main topic of this research is to decrase human power load when pushing wheelbarrow with the addition of engine as a power source. Design criteria for wheelbarrow engined is to has a maximum forward speed equivalent to ability of human beings, which is 5 KPH. Design using CAD software. Adding engine is expected to increase the wheelbarrow transport capacity. The results of wheelbarrow with engine design is using 2-stroke engine with a capacity of 0.78 iii KW used from mowers engine. Functional part of the main functions are supporting frame, tub, engine cradle, 2 stroke engine, gearbox, eccentric gear, chain and sprocket, wheel, fuel tank, throttlecontrol, and handle grip. From the analysis and calculation is determined using the frame, wheels and tubs of wheelbarrow Artco branded, 2-stroke engine with a capacity of 0.78 KW, using a gearbox reduction ratio 1:20 type 40, roller chain size 40, sprocket 14T and 45T. The results from this research are design wheelbarrow with engine that have forward speed 5 KPH.

Abstrak: In oil palm harvesting, falling fruit bunches have a considerable potential energy, which can be captured and used to power the wheelbarrow in evacuating the fruit bunches. This study was conducted to measure the coefficient of rolling resistance of a wheel barrow, analyze the potential energy of falling fresh fruit bunch, design a conceptual design of the catchment platform and evacuation machine. Measurement of wheel rolling resistance and soil penetration resistance were conducted at the evacuation track in the field. The energy potential of the falling fruit bunches was measured during harvesting, with variations of the fruit height of approximately 3 m, 8 m, 9 m and 15 m. The results showed that machine mobility in the field was very good. Soil penetration resistance was in the range of 16.44-22.10 kgf/cm2. Average coefficient of rolling resistance of the wheels was 0.159. Potential energy of falling fruit bunches were in the range of 0.44-4.44 kJ. Theoretical traveling distance of the wheel barrow using the captured potential energy was in the range of 2.27 m - 22.98 m. A conceptual design of catchment flatform and evacuation machine was designed.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
