Detection of porcine contamination in food material by employing PCR techniques is integral in halal food confirmation. However, PCR is both costly and laborious, particularly in DNA isolation method. This study explores several different methods in DNA extraction for PCR amplification in bovine and porcine raw and boiled meat samples. Four methods for DNA extraction (conventional PCI method, DNA isolation kit, alkaline-based method, and a DNA lysis buffer-only from the same kit) was employed followed by PCR using primers from previous studies and compared for DNA quality and quantity (in six replicates) and PCR amplification on the best three DNA samples. This study shows that in all samples, the conventional method had the best DNA yield based on nanodrop measurement, followed by an alkali-based method, buffer-only method, and DNA isolation kit. Each method except lysis-buffer only had at least one sample with good DNA quality. Conventional and isolation kit showed reliable positive PCR detection for all porcine and bovine samples (92% positive). Using the alkaline-lysis method, DNA was amplified reliably on boiled meat samples (83% positive). Lysis-buffer-only method did not show consistent PCR amplification on the samples used (50% positive). The conclusion was that conventional PCI method and DNA isolation kit showed high reliability in PCR amplification of bovine and porcine meats, both raw and boiled. While high DNA yield was obtained using the alkaline-lysis method, PCR amplification was only successful on boiled samples. Lysis-buffer only method yielded in poor DNA quality and was not able to result in reliable DNA amplification.Keywords: DNA extraction methods, halal, Porcine food contaminants.

Myxobolus koi is a type of parasite that infects many freshwater fish through myxospores, resulting in a disease called myxobolosis. This research aimed is to investigate the clinical symptoms that occur in the gills of infected Koi carp (C. carpio). The utilized methods in this study are molecular detection, histopathology, and Scanning Electron Microscopy (SEM). Koi carp samples that are suspected to be infected with Myxobolus koi show several clinical signs, such as swollen and pale-colored gills and gill covers (opercula) that do not close completely, as well as white spots that appear on the edge of the lamella. The results of this study showed that through histological observations, there were changes characterized by hyperplasia of the primary lamella cartilage that envelops parasitic cysts and the encapsulation process that surrounds the cysts by gill cartilage in infected fish;SEM showed oval and elongated spores of a size of ± 12 µm (800x). TheDNA template from gill tissues in clinically infected and uninfected fish was examined byPCR testing with primers ERB 1 (Forward) and ERB 10 (Reverse); the results of electrophoresis in infected fish were detected at 2000 bp. Keywords: Cyprinus carpio, Histopathology, Molecular Detection, Myxobolus koi, Parasite, SEM.
