    The river pollution or contamination is caused by several factor such as growth in the industrial development, urbanization transformation and increase in the population density. River pollution may negatively effect human health, well-being and the environmental condition. Juru River basin is among the contaminated rivers in Malaysia which located in Pulau Pinang, Malaysia. Even though many green activities have been implemented but the result still the same. In this paper, Principal Component Analysis is employed for pinpointing the most influential parameter in Juru River Basin. It is important to know what the root cause of the water quality is. There are 20 parameters in measuring water quality, therefore, PCA is useful statistical techniques in handling a larger number of parameter. Bimonthly data is gathered from 2008 to 2017 Department of Environment (DOE). From the analysis, there are eight influential parameter that have to control which are salinity, conductivity, dissolved solids, calcium, zinc, pH, arsenic and ammonia nitrogen. We expect to help the DOE to put the focus on these eight parameters instead of monitoring 20 parameters. Once we control all of the identified influential parameters, the rest will be in-control.

    The multiple-disciplinary article has been written belong to the Virtual Team area. Unfortunately, a lack of analysis is not measured by publication trends related to this field. Hence, these studies to demonstrate the trend of "Virtual Team" scientific literature from 1991 until 2020. Specifically, a total number of 1, 782 publications were investigated in the SCOPUS database by using Publish and Perish software to collect all the literature. The trend of a virtual team has received considerable attention since 1991, and highly most of the research in the virtual team was published in the computer science field. The top 50 keywords are presented from the growth of the virtual team literature and research interests, thus the potential directions for future research are proposed.
