Abstract
Background subtraction is a preliminary technique used for video surveillance and a widely used approach for indexing moving objects. Arange of algorithms have been introduced over the years, and it might be hard to implement the algorithms on the embedded platform because the embedded platform comes up with limited processing power. The goal of this study is to provide a comparative analysis of available background subtraction algorithms on the embedded platform: - Raspberry Pi. The algorithms are compared based on the segmentation quality (precision, recall, and f-measure) and hardware performance(CPU usage and time consumption) using a synthetic video from BMC Dataset with different challenges like normal weather, sunny, cloudy, foggy and windy weather.

Abstract
Chinese sausage is traditional air-dry sausage that loved by the Chinese community around the globe. This sausage can be served alone after steam cook or cook with other ingredients to create other tasty Chinese delicacies. However, a manual hand cutting process is required to cut out the sausage linking twist during the sausage’s packaging phase. This hand cutting process is tedious, time consuming and danger to workers. This study has proposed two types of sausage casing twist detector using image processing technique based on HSL and RGB colour characteristic and a set of blob detection technique to detect sausage casing twist blob on the output image. Hue, green-blue and red-blue colour characteristics are found being significant to represent the sausage casing twist in the sample images and used in the proposed algorithms. The RGB based algorithm is capable to produce a low noise image with SNR of 3.73dB as compared to Hue-based detector at -8.89dB which unsuccessful to remove shadow and object outlining of the output image. The proposed blob detection algorithm is able to detect 73.02% of the blob in hue-based image while 94.18% in RGB based image. The false detection rate in hue-based image has reached 333.33% compared to 12.17 % in RGB based image.

Abstract
Moving towards a modern age, Augmented Reality (AR) can be considered as one of the fastest developing technologies every year wherein it is enhanced by computer-generated perceptual information and sometimes across multiple sensory modalities, including visual and text. However, students have not been exposed to this technology since they are stuck with a narrow-minded conception of using papers even though it can be too overwhelming for them since they have to read the study books, brochures, and pamphlets to get information about their universities especially for the new students who recently registered and for the visitors. To overcome this problem, we are developing an application “AR UniMAP: Pauh Putra Residential College Interactive Map”. This project aims is to develop an informative ARMap along with some additional information about the campus for the students and visitors through interactive communication through the proposed system. Smartphone with the support of ARCore is used as the main platform for the application to be implemented in such a way to display the visuals of the buildings and each room in the campus through 2D and 3D along with some additional information through text pop up on the left and right side of the smartphone screen.. The key to this architecture is to expose university students with the AR technologies and to make it easier for them to access information about their university.

Published: March 2021

AbstractKoi (Cyprinuscarpio) hatchery and aquaculture sector is highly beneficial as it is one of the Indonesian and international superior commodity. However, Koi are susceptible to pests and diseases. One of the diseases is Myxobolusis which is caused by theMyxobolussp. parasite. The clinical symptom of Myxobolusis are lumps (boils) on the gills and cloudy reddish fluid secretion similar to pus. This research aims to determine the infection profile of Myxobolus through histology observation on gill tissue damage of koi cultivated in a ground pond. This research uses a descriptive method and a quantitative approach. This research observes the gill tissue damage of koi collected from the ground pond of Nglegok, Blitar Regency. The researcher observes the type of damage using a microscope with a magnification of 400x. This research uses a scoring method to assess the damage. Based on the result of histopathological observation, the infected fish exhibits oedema, haemorrhage, hyperplasia, lamellar fusion, and vacuolization. The percentage (%) of tissue damage in Myxobolus infected koi are 72%, 33%, 77%, 75% and 52% respectively. The average score shows moderate to severe damage levels. The observation result on water quality parameter (temperature, pH, DO, and CO2), as supporting parameter in water quality management, shows a tolerable condition and is not the primary cause of Myxobolus sp. infection. However, the transmission of infection may occur due to the presence of other organisms that act asMyxobolussp. host.
