Judul: Rancangan Dan Uji Teknis Prototipe Mesin Penggiling Padi Tipe Piringan Pipih
Abstrak: Beras adalah bahan makanan pokok bangsa Indonesia sejak ribuan tahun yang lampau. Sistem bercocok tanam padi, teknologi pengolahan padi menjadi beras dan teknologi pengolahan beras menjadi nasi boleh dikatakan merupakan bagian dari kebudayaan bangsa. Sistem bercocok tanam padi dan teknologi pra panen, panen, dan pasca раnen mempunyai sejarah perkembangan yang amat tua dan kaya dengan cara tradisional yang penuh adat istiadat dengan penggunaan alat-alat sederhana sampai cara moderen dengan penggunaan mesin yang digerakkan oleh motor. Meskipun sistem dan teknologi tersebut telah mampu membawa Indonesia ke gerbang cita-cita swasembada beras, namun haruslah diakui bahwa dibidang pasca panen padi, sekarang masih memerlukan impor alat-alat dan mesin-mesin pengolahan padi. Alat-alat pasca panen buatan dalam negeri baru terbatas pada alat perontok, alat pengering sederhana, alat pembersih gabah, alat penggiling dan penyosoh "Engelberg" hasil modifikasi, serta alat pemecah kulit "gilingan monyet" (Hadi K. Purwadaria, et al. 1983). Tujuan rancangan mesin penggiling padi tipe piringan pipih ini adalah merancang mesin penggiling padi dengan konstruksi kompak dan mudah dalam pengoperasiannya, serta bersifat serbaguna dapat untuk menggiling kedelai dengan cara mengganti piringan penggilingnya. Prinsip kerja mesin ini adalah: 1. Pengupasan dilakukan dengan menggunakan duabuah piring- an pipih 2. Kedua piringan terpasang sejajar dalam posisi vertikal dan sejajar. Salah satu piringan berputar, sedangkan yang lainnya dalam keadaan diam 3. Mesin bekerja secara kontinyu…dst

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
