Judul: Prevalensi Nematoda Gastrointestinal Anjing di Kecamatan Lore Barat Kabupaten Poso, Sulawesi Tengah
Abstrak: Infeksi nematoda gastrointestinal pada anjing menyebabkan gangguan kesehatan hewan dan berpotensi zoonosis. Penelitian ini dilakukan untuk menentukan prevalensi dan intensitas infeksi nematoda gastrointestinal pada anjing di Kecamatan Lore Barat Kabupaten Poso. Pemeriksaan koprologi dilakukan dengan metode pengapungan sederhana serta penghitungan telur dengan kamar hitung McMaster. Dalam penelitian ini, prevalensi nematoda gastrointestinal dianalisis dalam kaitannya dengan infeksi tunggal dan ganda, jenis kelamin dan usia. Dari total 57 sampel yang diperiksa, telur Toxocara sp. dan hookworm ditemukan pada 39 sampel (79.31%). Sebanyak 68.42% merupakan infeksi tunggal dan 10.52% ditemukan mengandung lebih dari satu jenis nematoda. Prevalensi infeksi hookworm dan Toxocara sp. pada anjing betina lebih tinggi dibandingkan anjing jantan. Prevalensi Toxocara sp. dicatat lebih tinggi di anjing muda. Namun, penelitian ini menunjukkan bahwa anjing tua lebih rentan terhadap infeksi hookworm. Toxocara sp. dan hookworm antara jenis kelamin dan kelompok umur ditemukan secara statistik tidak signifikan (p>0.05). Intensitas infeksi Toxocara sp. dan hookworm tergolong kategori tinggi dengan rerata jumlah telur masing-masing 567 dan 1041 EPG.

Judul: Neosporosis Sapi: Studi Pendahuluan di Lore Barat, Kabupaten Poso, Sulawesi Tengah.
Abstrak: Neospora caninum is recognized as a major cause of serious abortion in varieties of wild and domestic animals around the world especially in cattle. This disease causes severe economic losses among dairy and beef cattle due to the loss of foetus as well as a decrease in milk and meat production, which is believed as an opportunistic zoonotic agent. A cross-sectional study was carried out to determine the prevalence of Neospora caninum antibodies in cattle from five villages in West Lore Subdistrict of Poso Regency, Central Sulawesi, Indonesia. Serum samples were collected from 44 local beef cattle tested for detection of immunoglobulin (Ig) G antibodies against N. caninum using an indirect multi-species enzyme-linked immunosorbent assay (ELISA) commercial test. Seroprevalence of Neospora caninum in local beef cattle in West Lore, Poso Regency, Central Sulawesi is 11.36%. Gender and ages have not affected the prevalence of this parasite. This study gives information about the first serological evidence for the presence of natural N. caninum infection in local beef cattle from West Lore. It is recommended to do further investigations and to design suitable controlling strategies., Neospora caninum dikenal sebagai penyebab utama aborsi pada hewan liar dan domestik di seluruh dunia, terutama pada sapi. Penyakit ini menyebabkan kerugian ekonomi yang parah pada sapi perah dan sapi potong karena sapi kehilangan fetusnya, serta terjadi penurunan produksi susu dan daging. Parasit ini termasuk sebagai agen zoonosis oportunistik. Kajian lintas seksional dilakukan untuk mengetahui prevalensi antibodi Neospora caninum pada sapi dari lima desa di Kecamatan Lore Barat Kabupaten Poso, Sulawesi Tengah, Indonesia. Sampel serum dikumpulkan dari 44 sapi potong lokal untuk mendeteksi antibodi imunoglobulin (Ig) G terhadap N. caninum menggunakan indirect multi-species enzyme-linked immunosorbent assay (ELISA). Seroprevalensi Neospora caninum pada sapi potong lokal di Lore Barat, Kabupaten Poso, Sulawesi Tengah adalah sebesar 11,36%. Jenis kelamin dan usia tidak mempengaruhi prevalensi parasit ini. Penelitian ini memberikan informasi tentang bukti serologis pertama adanya infeksi N. caninum alami pada sapi potong lokal di Lore Barat. Disarankan untuk melakukan investigasi lebih lanjut prevalensi parasit tersebut pada anjing sebagai sumber infeksi horizontal agar dapat merancang strategi pengendalian yang tepat.

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.
