Abstrak: The using of drill method in resin tapping requires relatively small tap area. Drill method has disadvantage, that is the high increasing rate of tap area. Therefore, the research that focus in wound renewal by enlarge the size of existing drill hole is needed to decrease the high increasing rate of tap area. This study use a complete random design where the consists of four treatments method; quarre method, one frequency drill method, two frequency drill method and three frequency drill method. Based on Duncan test, the result shows that the productivity of quarre method is 89.08 g/tapping area/day and it is higher than the productivity of drill method. The same productivity showed by the various frequency on drill methods. Drill method with two frequency is an optimum drill method considered by the productivity and the increasing rate of tap area, which the productivity reaches 51.39 g/tapping area/day and the increasing rate of tapping area is 18.4 cm/month.

Abstrak: The current method of tapping pine resin is quarre method. A method of tapping is simple to be implemented, but using this method causes the high level of damage to the tree. In order to decrease the rate of the damage, drill method can be used as an alternative. The purpose of this experiment was to find out the optimum number of tapping areas to obtain an optimal productivity of resin in one tree. Pine trees were tapped using a mechanical drill and stimulant was then sprayed. Experimental design used was completely randomized design (CRD). The data were obtained from the six treatments, i.e., one to six of tapping areas on the sample trees with a diameter ≥30 cm. Each treatment consisted of 10 sample trees. The results showed that resin production in line with quantity of tapping areas, but the average resin production per tapping area will be lesser. The rate of resin production increased up to three tapping areas per tree. The addition of tapping areas more than three reduced rate of production. The optimum quantity of tapping area by the drill method in pine trees are three tapping areas. The average production from that optimum method is 38.02 gr/tree/day

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.
