Judul: Produktivitas Penyadapan Getah Pinus dengan Metode Bor tanpa Pipa
Abstrak: Drill method is a method of tapping that gives many advantages but also has many deficiency, such as the use of pipes is not efficient and add more costs, it also difficult to move the resin from the receptacle into a drum, and it can’t accommodate the resin which came after the tapping period. This research uses five different treatments. Treatment A by using the quarre method without stimulansia as a control, treatment B by using the quarre method with stimulansia, treatment C by using the drilling method with a pipe, treatment D by using drilling method without a pipe, and treatment E by using the drill method with a pipe and resin shelters not on a pipe. The tree sample used in every treatment is 10. The research shows that the treatment D by using drill method without a pipe gives the highest resin productivity however it has more water content and higher levels of impurities than the other drill method designed. Thus, drill methods without a pipe, is a tapping solution that capable of producing qualified resin also has not destructive to trees compared to the quarre method. It also can produce more resin with an economical and practical surplus than the drill method by using a pipe.

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: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
