Judul: Peningkatan sifat fisis dan mekanis kayu dengan polimerisasi katalis panas
Abstrak: Salah Satu usaha yang kini banyak dilakukan guna memodifikası sifat-sifat kayu sehingga nantinya dihasilkan produk yang mempunyai sifat-sifat fisik dan mekanik yang tinggi adalah proses impregnasi monomer-monomer vinil kedalam kayu. Polimer padat seperti polimetil metakrilat (MMA) telah banyak dipakai guna meningkatkan sifat-sitat dasar kayu.

Judul: Pengaruh Tingkat Konsentrasi Polistiren pada Polimerisasi Pemanasan Terhadap Sifat Fisis dan  Mekanis Kayu Plastik
Abstrak: Kayu telah lama dikenal masyarakat sebagai bahan yang serbaguna, baik untuk balian bangunan, dekorasi, sumber energi, senjata liiaupun untuk kegunaan laimya. Sebagai bahan yang serbaguna dan dinilai pentina keberadaannya maka dalam perkernbangannya kayu banyak mengalami modifikasi. Hal ini didorong oleh semakin sulitnya diperoleh kayu, harga kayu solid mahal, sulitnya diperoleh kayu yang kuat atau awet, dan adanya tuntutan teknologi. Maka sejak saat itu, orang mulai belusaha untuk membuat kayu dengan menggunakan teknologi tertentu sehingga diperoleh sifat kayu yang diinginkan. Salah satu teknologi yang digunakan adalah dengan pe~nbuatan Wood Po[yriler Conlposite W C ) atau yang lebih dikenal sebagai kayu plastik. Kayu plastik melnpunyai sifat yang keras dan kuat. Sehingga niemungkinkan untuk digunakan sebagai bahan yang dalam penggunaannya mendapat beban yang besar. Juga memungkinkan digunakan kayu yang kwang keras, kwang kuat sebagai bahan baku kayu plastik sehingga akan melnperbaiki sifat-sifat kayu tersebut. Dalam pembuatan kayu plastik dapat dilakukan dengan polimerisasi pelnanasan dan poli~nerisasria diasi. Dua metode polimerisasi tersebut mempunyai kelebihan dan kekurangan. Kelebihan dari polilnerisasi radiasi adalah polimerisasi &an berlangsung lebih merata, pencemaran udara yang ditimbulkan rendah. Kemgiannya adalah tingginya investasi awal. Sedangkan kelebihan dari polimerisasi penianasan adalah rendahnya investasi. Kekurangamya pencemaran udara yang ditimbulkan lebih besar. Untuk mempercepat terjadinya polimerisasi pada polimerisasi pemanasan biasanya digunakan katalis.

Judul: Dog Ticks Infestation and Its Correlation to Tick-Borne Diseases.
Abstrak: Ticks infestation on dog could lead to itchiness, anemia, skin disorders, and tick-borne diseases, such as Ehrlichiosis, Babesiosis, Anaplasmosis and Rocky Mountain Spotted Fever. Besides dogs, Ehrlichiosis were known to be zoonotic. Pre-mature stage tick life cycle that occur outside its host, will enhance contacts between ticks and human. The study of ticks infestation and tick-borne diseases on the dog is necessary, because it has not a lot of information about the diversity, prevalence and degree of ticks infestation in Indonesia. Ticks survey, included ticks sampling and dogs blood test were performed at Animal Police Directorate Security Agency (Baharkam) and Atang Sendjaja Air Force (ATS). Meanwhile ticks sampling also data of cases of ticks infestation and diseases transmitted obtained from 21 veterinary clinics in Bogor, Jakarta and Bandung. All ticks samples stored in bottles containing 70% alcohol for identification. Blood tests performed for Ehrlichiosis, Babesiosis and Anaplasmosis diagnosis. The identification results of the 950 ticks samples that obtained from 97 dogs of Baharkam, ATS and veterinary clinics in Bogor, Jakarta and Bandung, showed only one ticks species, Rhipicephalus sanguineus. This ticks belong to three-host tick, which require three hosts to complete its life cycle. Each ticks stage need a host, either same dog (if it is in place there is only one or a few dogs), as well as different dogs. Research in Baharkam conducted on 81 dogs (53 males and 28 females). The prevalence of dogs infested by ticks was 67.90%. The percentage of male dogs that infested by ticks are larger (69.81%) than female (64.29%). Based on Chi-Square test, there was no relationship between sex and breed of dog with degree of ticks infestation. Generally dogs infested with mild infestation category (41.98%), meanwhile moderate category was 18.52%, 2.47% high and 4.94% very high. The dog’s body region that the most infested by R. sanguineus was dog's back. Probably these body regions were be preferred because they are less accessible for the dog to remove them with its paws. Collection of ticks with tick-drag on Baharkam grass field showed positive results on the field that was more often used to practice by dogs. The samples that obtained was larvae stage ticks with density 152 larvae on 215m2 area of the field. Adult stage ticks and several adult females which laying eggs on the cage wall were obtained in the dog kennels. Whole of male and female ATS dogs infested with ticks (14 dogs). In general, dogs infested with very high infestation category was 64.29%, compared by high degree category (21.43%) and moderate (14.29%). Ticks predilection were found mostly on the dog’s head – neck. On ATS grass field did not reveal any ticks, but positively inside the kennels. It happens probably because dogs are rarely released from the kennel, so that the ticks was did drop-off inside the kennel. The total cases of ticks infestation of dogs at Bogor, Jakarta and Bandung veterinary clinics in 2008 until June 2013 as many as 731 cases. In general, there was an increases of the ticks infestation prevalence at three cities in that range
