Judul: Studi analisis hidrolis pada undersluice sebagai konstruksi pelengkap bendung untuk pengendalian sedimen
Abstrak: Tujuan dari penelitian ini adalah untuk mempelajari pengaruh debit aliran, tinggi lubang undersluice, bukaan pintu undersluice terhadap tinggi muka air di hulu tinggi muka air di hilir, serta kecepatan aliran di lubang, mendekati lubang undersluice, serta di pintu undersluice. 1 Penambahan bukaan pintu undersluice pada keadaan free flow akan mengakibatkan penurunan elevasi di hulu under- sluice, dan sebaliknya. Kecepatan aliran mendekati lubang undersluice semakin kecil dengan setiap penambahan debit. Hal ini diakibatkan karena penambahan elevasi muka air di hulu. Sedangkan pada penambahan debit yang sama kecepatan aliran di dalam lubang undersluice dan kecepatan aliran pada pintu under- sluice akan semakin besar pula. Kecepatan aliran di lubang undersluice akan sama dengan kecepatan aliran pada pintu undersluice. Koefisien pengaliran undersluice (C) didapatkan dengan membuat analisa regresi linear antara debit aliran dan parameter yang mempengaruhinya, sesuai dengan persamaan yang digunakan. Program komputer untuk parameternya pada undersluice dua mempredikS1 dimensi seperti elevası, dan kecepatan aliran. parameter- prototypenya, Hal 101 dilaku- kan dengan terlebih dahulu menentukan tinggi lubang under- sluice rencana.

Judul: Analysis of Drainage Rates in Soils with Sheetpipe Subsurface Drainage System
Abstrak: Pada area perakaran tumbuhan perlu dilakukan pengaturan drainase yang efektif agar muka air tanah dapat dijaga sesuai dengan yang dibutuhkan. Tujuan dari penelitian ini adalah menganalisis laju drainase bawah permukaan dengan menggunakan sheetpipe secara eksperimen dan simulasi komputer serta menentukan perubahan laju drainase terhadap waktu pada tekstur tanah lempung liat berpasir. Penelitian ini meliputi pengamatan penurunan muka air tanah dan laju drainase. Hasil penelitian menunjukkan penurunan water table maksimum pada eksperimen terjadi pada 6 menit pertama sebesar 10,1 cm, dan pada simulasi Hydrus sebesar 26 cm. Penurunan terendah masing-masing pada menit ke-60 sebesar 0,03 cm. Penurunan total water table pada eksperimen sebesar 32 cm dan pada simulasi sebesar 33 cm. Laju drainase paling besar mencapai 0,3300 liter/detik pada menit pertama, dan paling rendah pada menit ke-60 yaitu 0,0039 liter/detik. Persamaan regresi pada penurunan water table menggunakan persamaan polinomial pangkat 6 dengan koesfisien determinasi R2 = 0,9976. Persamaan regresi pada laju drainase menggunakan persamaan eksponensial dengan koefisien determinasi R2 = 0,9918.

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
