Publisher : Program Pascasarjana Universitas Sriwijaya

This research focused of the effect of water pollution on aquatic fauna at Dhaka mega city, Bangladesh. Dhaka is an over populated capital city of Bangladesh. The rapid urban expansion, highly demographic growth, industrial development of this mega city have been including in a polluted city. The industrial and municipal waste material have polluted the wetlands basin of this city. Aquatic fauna of these wetlands basin are endanger for pollutant substances. The aquatic records and have been collected by field observation. The water quality of this mega city have been explored by sample collection and lab analysis. Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are less than standard level. As a result the water body fully toxic that condition is not free for living organism. On the other way, the availability of Total Dissolved Solids (TDS), Lead (Pb) and Cadmium (Cd) are catastrophically high from standard level. So the water quality fully polluted and it is not sustainable for aquatic fauna.

Sriwijaya Journal of Environment Vol 4, No 2 (2019): Aquatic Environment
Publisher : Program Pascasarjana Universitas Sriwijaya

El-Nino results in reduced air mass in most parts of Indonesia and can cause drought. In the La-Nina phase some parts of Indonesia will get more water vapor resulting in increased frequency of rain. Increased rainfall has an impact on groundwater availability. Groundwater availability illustrates the condition of water in the soil which is useful in many sectors of life, especially in the agricultural sector. This study aims to see the relationship between the El Nino and La Nina phenomena strongly by using SOI indicators on groundwater availability in Palembang. In the Strong El-Nino phase in 1994 and 1997 the SOI index had a moderate correlation with groundwater availability of 32% and 39%. In 2015 the correlation of SOI to groundwater avability was 79% indicating a strong relationship. In 2008 and 2011 which was a strong La-Nina phase the SOI index correlation value for groundwater availability was 46% and 45%, respectively, which indicated a moderate correlation.

This research was conducted to treat rubber industry wastewater by using fly-ash as an adsorbent and hybrid membrane UF-RO to produce clean water. In this research was analyzed the effect of flow rate of wastewater treatment to remove turbidity, zinc, and iron. The applied flow rate of membrane separation was of 7 L/min and 14 L/min and the operation time was of 90 min respectively. The rejection concentration of turbidity, zinc, and iron decreased with increasing the flow rate at adsorbent fly-ash. Whereas at the hybrid membrane UF-RO, the rejection concentration of turbidity, zinc, and iron increased with increasing the flow rate. The maximum rejection of turbidity was 24.26%, 95%, and 67.89% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of zinc was 91.67%, 59.70%, and 14.81% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of iron was 62.24% and 21.62% for adsorbent fly-ash, UF membrane respectively. The pollutants concentration in the permeate was met the quality standards of the Indonesian health department through the decision of the Minister of Health number 907 of 2002 concerning supervision of the quality of drinking water.

Publisher : Program Pascasarjana Universitas Sriwijaya

Time dependent reproduction number (TD – R0) is a measure of secondary infections or transmissibility of a disease useful in monitoring changes in the rate of infection and assessing policies put in place to control the spread of a disease. In this study we used daily infections situation report of COVID – 19 published by the Nigeria Centre for Disease Control (NCDC) to estimate Nigeria’s TD – R0 and then repeated the same for the six geo – political zones in the country. Estimates of TD – R0 values for the country from the 23rd of March – 27th of May 2020 fluctuated with a maximum of 2.3 (95% CrI) on the 19th of April and a minimum of 0.83 (95% CrI) on the 16th May 2020. Despite the decline in TD – R0 since the early stages of the outbreak of COVID – 19 in Nigeria suggesting a fall in the expected rate of secondary infection apart from the northwest and the northeast geo – political zones values remain above 1.0 for other zones and the country, generally. The Kolmogorov – Smirnov (KS) test was used to test the null hypothesis stating that the means of TD – R0 across the geo-political zones does not follow the same distribution pattern. After making adjustments for Type 1 – error we accepted the null hypothesis (p < 0.05) for six pairs of geo-political zones. We conclude that our findings are significant in studying the COVID – 19 epidemic in Nigeria and important in evaluating the strategies deployed by governments at the national and regional levels, thus, the same method can be replicated across Africa.

Sriwijaya Journal of Environment Vol 6, No 3 (2021): Environmental Health and Safety
Publisher : Program Pascasarjana Universitas Sriwijaya

The advancement of science and technology plays a very important role in encouraging industrial progress. In addition to having a positive impact on the economy, industrial progress, on the other hand, has a negative impact in the form of pollution. One of the industrial activities is the coal mining industry. Various ways to deal with pollution include the electrolysis method, in which the liquid waste is flowed by a direct electric current through the electrode media. The purpose of this study was to examine the length of electrolysis and the amount of electric current used to reduce dissolved ions and total dissolved solids from coal stockpile wastewater. The method used is a survey in the form of sampling followed by waste treatment using electrolysis. The results showed that the combination of electrolysis time of 120 minutes and electric current of 3 A showed that the highest dissolved ions decreased by an average of 1,692.3 µs / cm from the initial pre-treatment of 1772 µs / cm. The highest mean decrease in total dissolved solids was 660.67 ppm from the beginning before treatment of 909 ppm.
