Judul: Gastrointestinal Helminth Infections in Horses in The Cipanas Palace
Abstrak: Infeksi cacing saluran pencernaan dapat menyebabkan penyakit dan memiliki dampak besar pada kuda. Penelitian ini bertujuan untuk mengidentifikasi dan menghitung derajat infeksi kecacingan pada kuda di Istana Cipanas. Sampel feses diambil dari kandang individu kemudian dibawa ke Laboratoium dengan menggunakan coolbox. Sampel diperiksa dengan menggunakan metode pengapungan sederhana, McMaster dan filtrasi bertingkat untuk menentukan infeksi cacing saluran pencernaan. Sampel yang positif nematoda strongyle di siapkan untuk kemudian dilakukan pemupukan feses untuk mendapatkan larva infektif (L3) untuk di identifikasi lebih lanjut. Hasil penelitian ini menunjukkan bahwa semua kuda (18) di Istana Cipanas positif terinfeksi nematoda strongyle. Jumlah rata-rata telur tiap gram tinja (TTGT) sebesar 669,44. Kategori infeksi mulai dari infeksi ringan hingga sedang. Delapan kuda terinfeksi nematoda strongyle dengan kategori infeksi ringan dengan TTGT 50 hingga 450. Sepuluh kuda masuk dalam kategori infeksi sedang dengan TTGT 500 hingga 1800. Berdasarkan identifikasi larva, jenis nematoda strongyle yang ditemukan pada kuda di Istana Cipanas yaitu 100% Cyathostomine. Hasil penelitian menunjukkan jenis Cyathostomine yang ditemukan didominasi oleh tipe A sebanyak 67%, kemudian tipe C 20%, tipe G 5%, tipe D 3%, tipe F dan H 2%, dan tipe B 1%. Diperlukan strategi manajemen untuk mencegah infeksi ulang kecacingan pada kuda di Istana Cipanas., Gastrointestinal helminth infection cause diseases and have great impacts to the horse. This research aimed to observe the type and degree of gastrointestinal helminth infection on horses in Cipanas Palace. Faecal samples were collected individualy in cage and transported to the Laboratory in a coolbox. Samples were examined using the simple floatation , McMaster and filtration methods to determine gastrointestinal helminth infections. Samples that were positive with strongyle nematodes were provided for fecal culture to obtain the infective larvae stage (L3) for further identification. The result showed all (18) horses in Cipanas Palace were positive to strongyle nematode infection. The average amount of strongyle nematode eggs per gram of feces (EPG) were 669,44. The category of infection were ranging from light to mild infection. There were 8 horses in category of light infection with 50 to 450 EPG and 10 horses in moderate infection category with 500 to 1800 EPG. Based on the larval identification, the strongyle types that found in horses of Cipanas Palace was 100% Cyathostomine. The result showed that the type of Cyathostomine species were type A as much as 67%, the type C 20%, type G 5%, type D 3%, type F and H 2%, and type B 1%. Management strategy is required to prevent the reinfection of helminth to horses in The Cipanas Palace.

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: 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.
