An Overview of IT Infrastructure Management in Small Medium Enterprise： A Case Study

Nowadays, information technology （IT） has become a part of the working culture and environment in many organizations. Originally, it is not a supportive tool to make any business successful, but it have become the backbone of successful business recently. Any non-IT organization could become dead and non-productive. When time comes, maybe it will fail in the business market. However, the usage of IT instruments must be carried out in good and conducive environment especially for business market. In this study, a basic and practical management about how to manage IT asset in small organizations will be discussed. Then this kind of management will be further discussed when the company become small medium organization. The implementation of IT infrastructure, the requirements, infrastructures, services, and platform from software to hardware and networking devices needs to be known. However, this study focuses on networking infrastructure such as networking equipments, servers, network monitoring software, costing, and management best practices.

Isolation,characterization and identification of plant growth-promoting rhizobacteria from the rhizosphere of Acacia mangium at sandy BRIS soil

This study has isolated,characterized,and identified potential plant growthpromoting rhizobacteria(PGPR)with multiple PGP characteristics(N_(2)-fixation,P-and K-solubilization,IAA,and siderophores production)from the rhizosphere BRIS soil of Acacia mangium.A total of 24 pure colonies were isolated and only 8 colonies were selected for further evaluation of the growth rate in 5%organic molasses medium supplemented with 2%KNO_(3).Based on the biochemical,potential PGP characteristics and growth performance,3 superior PGPR strains were selected and identified as Paraburkholderia unamae(UA1),Bacillus amyloliquefaciens(UA6),and Enterobacter asburiae(UAA2)by partial sequencing of the 16S rRNA gene.The selected bacterial strains either in single or mixed(UA1+UA6+UAA2)cultures have shown a significant biochemical estimation of the PGP characteristics.Each strain has its own PGPR traits superiority with UA1 showing the best PGP characteristic followed by UA6 and UAA2.The use of mixed bacterial strains was beneficial as it showed the best performance in N_(2)-fixation,siderophores production,and significant effect on corn phenology,growth and yield compared to using a single strain.These types of microbes showed potential to be used as biofertilizer and should be exploited more.

Integrated microalgae culture with food processing waste for wastewater remediation and enhanced biomass productivity

Waste generation from food manufacturing facilities poses a serious hazard like environmental degradation, water pollution, and land pollution due to its high nutrient composition. Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical content.Compared to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.
