Judul: Strongyloides Infection in Horses of East Sumba Regency, East Nusa Tenggara
Abstrak: Kecacingan pada kuda dapat menimbulkan kerugian ekonomi yang disebabkan oleh penurunan bobot badan, penurunan produksi bahkan kematian. Penelitian ini bertujuan untuk menghitung prevalensi dan derajat infeksi Strongyloides pada kuda di Kabupaten Sumba Timur, Nusa Tenggara Timur. Sebanyak 65 sampel feses kuda dikumpulkan di sepuluh kecamatan yaitu Kecamatan Tabundung, Kecamatan Lewa Tidahu, Kecamatan Nggaha Oriangu, Kecamatan Ngadu Ngala, Kecamatan Lewa, Kecamatan Kota Waingapu, Kecamatan Karera, Kecamatan Wula Waijelu, Kecamatan Pahunga Lodu dan dari Kecamatan Katala Hamu Lingu. Analisis feses menggunakan teknik McMaster dan flotasi sederhana. Hasil penelitian menunjukkan sebanyak 37 dari 65 kuda (57 %) terinfeksi cacing Strongyloides dengan derajat infeksi yaitu 162,99 TTGT. Berdasarkan nilai TTGT yang diperoleh hasil tersebut termasuk kedalam kategori infeksi rendah. Hasil uji chi-square dan uji Mann-Whitney U menunjukkan tidak adanya perbedaan nyata antara prevalensi dan derajat infeksi dengan umur dan jenis kelamin, Helminthiasis in horses can provide some economic losses due to loss of body weight, production, and even death of the animals. This study aimed to calculate the prevalence and intensity of Strongyloides infection in horses of East Sumba Regency, East Nusa Tenggara. A total of 65 fecal samples were collected in ten sub-districts, namely Tabundung District, Lewa Tidahu District, Nggaha Oriangu District, Ngadu Ngala District, Lewa District, Kota Waingapu District, Karera District, Wula Waijelu District, Pahunga Lodu District and Katala Hamu Lingu District. The samples were analyzed using McMaster technique and simple fecal flotation. The results showed that 37 out of 65 horses (57%) with intensity of Strongyloides infection is 162,99 eggs per gram (EPG) of fecal. Based on the EPG value obtained, these results were included in the category of mild infection. The results of the chi-square tests and Mann-Whitney U tests showed that there was no significant difference between the prevalence and intesity of infection with age and sex.

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: 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.
