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

Judul: Detection of Anaplasma spp., Rickettsia spp., and Borrelia spp., on Brown Dog Ticks (Rhipicephalus sanguineus) in Bogor
Abstrak: Caplak keras Rhipicephalus sanguineus merupakan ektoparasit yang biasa menginfestasi anjing dan berpotensi menjadi vektor zoonosis. Penelitian bertujuan mendeteksi jenis bakteri patogen yaitu Anaplasma spp., Rickettsia spp., dan Borrelia spp. dari caplak yang dikoleksi di Bogor. Sebanyak 77 ekor anjing diperiksa secara acak dari total 217 anjing dan ditemukan 142 caplak hasil koleksi dari enam ekor anjing. Sampel caplak dilakukan ekstraksi DNA untuk mendeteksi bakteri patogen dengan menggunakan metode PCR. Hasil PCR terhadap gen 17-kDa dan gltA menunjukkan satu sampel caplak positif terdapat Rickettsia sp. yang mendekati Rickettsia felis pada caplak yang menginfestasi anjing di Saint Kitts and Nevis. Hasil PCR terhadap gen GroEL menunjukkan satu hasil positif Anaplasma sp. yang mendekati Anaplasma platys pada caplak di China yang menginfestasi anjing sedangkan deteksi Borrelia spp. menunjukkan hasil negatif pada setiap sampel caplak.

Judul: Kinerja model pengering bangunan tembus cahaya dari plastik tahan UV untuk pengeringan buah kopi
Abstrak: Kopi merupakan komoditas ekspor yang memerlukan pengeringan sebelum dikonsumsi, sehingga kemampuannya dapat disimpan dalam waktu lama sangat menentukan mutu dan nilai ekonominya. Penyediaan sarana pengeringan yang memadai sangat dibutuhkan untuk mencapai tujuan tersebut. Sebuah model bangunan tembus cahaya untuk pengeringan kopi skala 1.5 ton sudah dirancang dan diuji coba. Bangunan tersebut berukuran 6 m x3 m, tinggi 2.46 m terbagi menjadi dua. yaitu atap 0.56 m dengan sudut kemiringan 32.4" dan dinding 1.9 m membentuk sudut kemiringan 85.6" terhadap lantai. Plastik tahan UV menutupi atap dan dindingnya. Penelitian ini bertujuan menguji kinerja model pengering bangunan tembus cahaya pada kapasitas maksimum. Percobaan dilakukan dengan mengeringkan kopi pada ketebalan 30 cm dan 40 cm (kapasitas penuh) dibantu blower 0.5 11P, 220 volt untuk mengalirkan udara pengering di dalam bangunan tembus cahaya dan mengeluarkan uap air bahan yang telah diuapkan dari bangunan tersebut. Hasil percobaan memperlihatkan bahwa penutup transparan mampu memanfaatkan 70% radiasi matahari yang jatuh di permukaannya. Pada kondisi radiasi termanfaatkan rata-rata sebesar 435.1 W/m². laju aliran udara sebesar 2520...
