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: The Infestation of Ticks (Acari: Ixodidae) on Dogs at Animals Hope Shelter Bogor
Abstrak: Caplak anjing berpotensi menimbulkan kerugian berupa penyebaran penyakit tular caplak baik pada hewan maupun manusia. Penelitian ini bertujuan mengidentifikasi spesies caplak yang menginfestasi anjing dan mengukur derajat infestasinya anjing yang dipelihara di Animals Hope Shelter Bogor. Koleksi sampel caplak dilakukan secara manual menggunakan pinset pada tubuh anjing yang dibagi menjadi lima regio, yaitu kepala dan leher, punggung, abdomen, ekor, serta kaki. Sampel dikoleksi dari 10 ekor anjing yang terinfestasi caplak selama lima menit pada setiap regio. Caplak di identifikasi dalam bentuk sediaan preparat kaca dengan kunci-kunci identifikasi caplak. Hasil penelitian menunjukkan bahwa hanya ada satu spesies caplak yang menginfestasi anjing di Animals Hope Shelter Bogor, yaitu Rhipicephalus sanguineus (Arachnida: Ixodidae). Infestasi caplak paling tinggi terjadi pada regio punggung dan kepala. Setengah dari populasi sampel anjing mengalami infestasi caplak ringan., Brown dog ticks potentially causes harm by transmitting Tick-Borne Diseases to both animals and humans. The aim of this research was to identified the species of tick that infested dogs and measured the infestation degree of ticks on dogs at Animals Hope Shelter Bogor. Ticks sample was collected manually by using tweezers from five regios of the dog’s body, which are head and neck, back, abdomen, tail, and foot. Sample was taken from 10 dogs that infested by tick for five minutes on each regio. Ticks identified in the form of mounted slide with tick identification keys. The result of this research showed that there was only one species that infested dogs at Animals Hope Shelter Bogor, that was Rhipicephalus sanguineus (Arachnida: Ixodidae). The highest number of ticks infestation was found at back and head regio. Half of the examined dog population had mild tick infestations.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
