Application of Activated Afzelia Africana and Acacia Albida Carbon for Removal of Pollutants in Textile Wastewater

/in /by

Adsorption of contaminants in textile wastewater onto activated carbon derived from two wood species has been studied using batch-adsorption techniques. This study was carried out to examine the removal efficiency of the low-cost adsorbent (Afzelia africana) AFA and (Acacia albida) ACA for the removal of heavy metals and other organic contaminants from textile effluents. The influence of contact time and adsorbent dose kept constant on the adsorption process was also studied. Removal efficiency increased with increase in contact time. The two adsorbents had an average removal efficiency of 60% at 90mins contact time for Zn. The ACA had higher removal efficiency for chromium at all contact times than AFA except at 120mins contact time where there existed a slight difference in the removal efficiency between the two adsorbents. Removal efficiency of iron was high between 58.18- 70.52% and 72.75-75.86% for AFA and ACA carbon respectively. This showed that iron had high affinity to the adsorbents surface. It was observed that AFA exhibited highest removal efficiency for nitrate at all contact times as compared to ACA. Results indicated that the freely abundant, locally available, low-cost adsorbent derived from the two wood species could be treated as being economically viable for the removal of contaminants from textile effluents.

Influence of Working Capital Management and Policy to Profitability of Retail Trading Sector in Indonesia

/in /by

Working Capital (WC) is an important aspect of any firms because of its correlation to risk (liquidity) and return (profitability). This research examines the influence of WC Management and Policy (WCMP) to profitability of 21 listed retail trading sector firms in Indonesia from 2011-2020 using panel data regression. In this research, WC Management (WCM) is measured by Cash Conversion Cycle (CCC) and its components which are Days Sales Outstanding (DSO), Days Inventory Outstanding, and Days Payable Outstanding (DPO); WC Policy is measured current assets divided by total assets or referred to as WC Investment Policy (WCIP) and current liabilities divided by total assets or referred to as WC Financing Policy (WCFP); and profitability is measured by Earnings Before Interest, Tax, Depreciation, and Amortization Margin (EBITDAM). The results show that firms can increase EBITDAM by shortening CCC, primarily through shortening DIO and lengthening DPO. Further, firms may improve EBITDAM by adopting a conservative WC Policy instead of an aggressive one, which means having higher current assets and lower current liabilities with respect to total assets.

Creative Destruction – An Inevitable Reality for the Financial Services Sector in Zambia?

/in /by

The financial services sector in Zambia has become increasingly exposed to the ever-growing challenges posed by mobile network operators (MNOs). The introduction of mobile money by MNOs has witnessed increased usage of mobile money services. During the same period, there has been a noticeable decline in the usage of digital banking services. The research study therefore sought to establish whether there was a correlation between increased usage of mobile money services and usage of digital banking services in Zambia. The study was quantitative in nature and was based on secondary data sources. Data from 19 of the 21 digital financial services providers in Zambia were analysed using times series trend analysis and simple linear regression analysis. In order to establish whether a correlation existed between increased usage of mobile money services and usage of digital banking services in Zambia, a t- test was conducted. This acted as a guide to the decision as to whether or not to accept or reject the null hypothesis. The study failed to reject the null hypothesis and therefore concluded that no correlation existed between increased usage of mobile money services and usage of digital banking services. However, the study expounded the research results in terms of Schumpeter, Christensen and Foster’s ideas on disruptive innovation.
