Judul: Indentifikasi ektoparasit pada anjing bali di Kintamani, Propinsi Bali
Abstrak: Ektoparasit pada anjing Bali (Kintamani) merupakan masalah yang sangat berpengaruh terhadap pembiakan dan pelestarian hewan tersebut. Tujuan penelitian ini adalah untuk mengetahui jenis-jenis ektoparasit yang sering menyerang anjing Bali pada habitat asalnya dan bagaimana cara mengurangi infestasi ektoparasit. Sebanyak 35 ekor anjing Bali dengan jenis kelamin, warna bulu, dan umur yang berbeda digunakan sebagai sampel. Ektoparasit diambil dengan cara menyisir bulu anjing dengan tangan atau langsung dengan pinset. Kemudian ektoparasit disimpan dalam alkohol 70% dan dibuat preparat. Hasil ektoparasit yang ditemukan antara lain Ctenocephalides canis, Ctenocephalides felis, Pulex irritans, dan Heterodoxus longitarsus. Ctenocephalides canis, Ctenocephalides felis, dan Pulex imitans termasuk dalam jenis pinjal, sedangkan Heterodoxus longitarsus termasuk jeins kutu. Keempat jenis ektoparasit tersebut dapat bertindak sebagai vektor-vektor penyakit yang berbahaya bagi manusia dan hewan-hewan lainnya.

Judul: Detection of Ancylostoma sp. and Cryptosporidium spp. in Kintamani Dog (Canis lupus familiaris) in Bandung and Bali
Abstrak: Anjing Kintamani adalah jenis anjing asli Indonesia dari Kabupaten Bangli di Bali. Saat ini, tidak banyak diketahui mengenai endoparasit yang dapat menginfeksi anjing Kintamani. Penelitian ini bertujuan untuk melakukan deteksi Ancylostoma sp. dan Cyptosporidium spp. yang dapat menginfeksi anjing Kintamani. Sebanyak 24 sampel feses diperoleh di Bandung dan Bali, dengan masing-masing lokasi diambil 8 dan 16 sampel. Metode pemeriksaan yang digunakan adalah metode kualitatif dengan pengapungan sederhana, metode kuantitatif menggunakan kamar hitung McMaster untuk menghitung telur tiap gram tinja (TTGT) dan metode Ziehl Neelsen. Metode molekuler juga digunakan untuk konfirmasi adanya Cryptosporidium spp. dengan Cryptosporidium Oocyst Wall Protein (COWP) sebagai gen target. Hasil menunjukkan bahwa 8,33% dari hewan positif Ancylostoma sp., 45,83% untuk Cryptosporidium spp., dan 4,17% positif dari kedua parasit. Rata-rata TTGT adalah 1.250, yang menunjukkan tingkat infeksi ringan. Uji molekuler menunjukkan 81,81% dari hewan terinfeksi Cryptosporidium spp. Hasil penelitian ini akan memberikan informasi awal mengenai infeksi endoparasit dan membantu dalam mengidentifikasi patogen pada ras anjing Kintamani., Kintamani dogs are an indigenous Indonesian canine breed from Bali’s Bangli Regency. The dog is included in the list of recognized dog breeds in the world. Currently, nothing is known about the endoparasites that can infect Kintamani dogs. This study aims to detect Ancylostoma sp. and Cryptosporidium spp. which can infect Kintamani dogs. A total of 24 fecal samples were obtained in Bandung and Bali, with 8 and 16 samples collected in each location. The examination method used was a qualitative method with simple flotation, a quantitative method using a McMaster counting chamber for counting eggs per gram of faeces (eggs/g), and the Ziehl-Neelsen method. The molecular method was also conducted to confirm the presence of Cryptosporidium spp. using Cryptosporidium Oocyst Wall Protein (COWP) as a target gene. The results showed that 8,33% of animals were positive for Ancylostoma sp., 45,83% for Cryptosporidium spp., and 4,17% were positive for both parasites. The eggs/g results were 1.250, indicating that the infections were minor. The molecular assay detected 81,81 % of animals infected with Cryptosporidium spp. The results of this study will tell us for the first time about endoparasite infections and help identify the pathogens that affect the Kintamani dog breed.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
