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: 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 3-Benzoil-7-hidroksiflavon dari Resorsinol
Abstrak: Flavonoid is the most abundant naturally-occuring polyphenolic compound with C6-C3-C6 carbon skeleton. Flavones is a group of flavonoid having a broad bioactivity spectrum. In this experiment, 3-benzoyl-7-hydoxyflavone was successfully synthesized via 2-steps from resorcinol. In the first step, resorcinol was acetylated with AcOH/ZnCl2 producing resacetophenone with 89% yield. Subsequently, benzoylation and rearrangement of resacetophenone using 2 equivalent of benzoyl chloride and 7 equivalent of K2CO3 in acetone produced 3-benzoyl-7-hydroxyflavone with 62% yield. Synthesis of 3-benzoyl-7-hydroxyflavone from resorcinol provided evidence for new reaction mechanism of flavon formation without Baker-Venkataraman rearrangement proposed by several previous researchers. All products in this study has been characterized spectroscopically.
