Judul: Parascaris Infection in Horses (Equus Caballus) in East Sumba Regency, East Nusa Tenggara
Abstrak: Kecacingan pada kuda merupakan masalah gangguan kesehatan, penurunan performa produksi, reproduksi, hingga kematian. Penelitian ini bertujuan untuk menghitung prevalensi dan derajat infeksi Parascaris pada kuda di Kabupaten Sumba Timur, Nusa Tenggara Timur. Sebanyak 65 sampel feses dikumpulkan dari 10 kecamatan dan diperiksa menggunakan teknik McMaster dan flotasi sederhana. Hasil penelitian menujukkan bahwa sebanyak 8 dari 65 kuda (12,3%) terinfeksi Parascaris. Derajat infeksi Parascaris (264,65 Telur Tiap Gram Tinja (TTGT)) masuk dalam ketegori infeksi sedang. Analisis statistika menunjukkan tidak ada perbedaan nyata prevalensi dan derajat infeksi Parascaris terhadap jenis kelamin dan umur., Helminthiasis in horses is a health disorder problem, decreased production performance, reproduction, and even death. This study aimed to calculate the prevalence and intensity of Parascaris infection of horses in East Sumba Regency, East Nusa Tenggara. A total of 65 fecal samples were collected from 10 sub-districts and examined using the McMaster technique and simple flotation. The results showed that 8 out of 65 horses (12.3%) were infected with Parascaris. The intensity of infection of Parascaris (264.65 eggs per gram of fecal (EPG)) was in the moderate infection category. Statistical analysis showed that there ware no significant difference in the prevalence and intensity of infection Parascaris with sex and age.

Judul: Strongyle Infection on Horses ( Equus caballus ) in East Sumba Regency, East Nusa Tenggara
Abstrak: Studi cross-sectional dilakukan pada bulan Agustus sampai Oktober 2020 untuk mengetahui prevalensi dan derajat infeksi strongyle pada kuda di Kabupaten Sumba Timur. Sebanyak 65 sampel feses diambil dari sepeluh kecamatan: Tabudung, Lewa Tidahu, Nggaha Ori Angu, Ngadu Ngala, Lewa, Kota Waingapu, Karera, Wula Waijelu, Pahungga Lodu, Katala Hamu Lingu. Pemeriksaan coprological untuk mendeteksi telur cacing strongyle dilakukan menggunakan teknik McMaster dan flotasi. Prevalensi parasit strongyle keseluruhan adalah 49,23% (32 dari 65) dengan derajat infeksi ringan (120,07 telur tiap gram tinja/TTGT). Tidak ada perbedaan nyata prevalensi dan derajat infeksi terhadap kedua jenis kelamin dan usia pada kuda., A Cross sectional study was conducted from Agustus to Oktober 2020 to estimate the prevalence and intensity of strongyle infection in horses in East Sumba Regency. A total of 65 faecal samples were collected from ten sub-districts: Tabundung, Lewa Tidahu, Nggaha Ori Angu, Ngadu Ngala, Lewa, Waingapu City, Karera, Wula Waijelu, Pahungga Lodu, and Katala H. Coprological examination for the detection of strongyle eggs was performed using McMaster and floatation technique. The overall prevalence of strongyle parasites was 49,23% (32 from 65) with a intensity of mild infection (120,07 eggs per gram/EPG). There was no difference in the prevalence and intensity of infection in both sex and the age of horses.

Judul: Sintesis BaTiO3 dari Campuran Ba(OH)2 dan TiO2 dengan Tambahan PbO
Abstrak: Piezoelectric material can generate electric field in response to applied mechanical stress. Conversely, they can stretch and contract in response to an electric field. This material can be used for many applications such as transducer, microphone, ultrasound, and pressure gauge. Barium titanate is a ferroelectric material with piezoelectric properties that can be synthesized easily. The aim of this study is to synthesis barium titanate from mixture of Ba(OH)2 and TiO2, also observe its optimum temperature and the effect of PbO addition. The method of synthesis was solid-state reaction and sol-gel method, then the products were characterized with x-ray diffraction (XRD). Based on XRD analysis, the optimum temperature for both methods was 800°C. Addition of PbO to BaTiO3 in the solid-state reaction formed a compound with formula of Ba1-xPbxTiO3. The addition has changed diffraction pattern peak at 2θ and strengthened its tetragonal structure. The best result was obtained at x of 0.5 which will form a compound of Ba0.5Pb0.5TiO3.
