Industrial progress has a positive impact on the economy. On the other hand, it has a negative impact in the form of pollution. The industrial activities include the coal mining industry. The electrolysis provides an effective way to reduce the pollutant from the wastewater through an electrochemical reaction between the cathode and anode. 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 had used the survey of coal stockpile location and wastewater sampling, then followed by waste treatment using electrolysis. The results show the increase in electrolysis time has a positive relationship decreasing dissolved ions in the coal stockpile wastewater. The combination between 120 minutes electrolysis time and 3 A electric current showed the highest decrease in dissolved ions by an average of 1,692.3 μs/cm from the beginning before treatment of 1772 μs/cm. The highest decrease in total dissolved solids was 660.67 ppm from the beginning before treatment of 909 ppm. This decrease had occurred because the longer electrolysis time and electric current are used greater, the more dissolved ions will be electrolyzed is in line with Faraday's law.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"439 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82889137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phytoplankton is sensitive to their environment and is used to monitor anthropogenic impacts. A study was carried out in a South-eastern Nigerian River between December 2017 and November 2018 in 6 stations; to assess the phytoplankton community, water quality, and anthropogenic impacts. Sand mining was a major activity in the river among others. The phytoplankton was sampled with the filtration method while water was collected and analyzed using standard methods. A total of 36 phytoplankton species were recorded with Chlorophyceae being the most abundant group. The most abundant species - Melosira granulata is a pollution indicator. The water quality and phytoplankton structure showed that the water was tending towards eutrophication. This is attributed to the observed anthropogenic activities and cumulative impacts of all the activities in the watershed. The impact of sand mining activities was observed more in the downstream stations (4 – 6) while perturbation from swimming children and related activities was observed in station 1. The community structure reflected the impacts of the activities while CCA showed the major water quality parameters that influenced the phytoplankton community structure.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"18 8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75029409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are six main influencing factors (rainfall, slope, land use/cover, lineaments, drainage density, and Lithology) selected for groundwater recharge zone mapping. The thematic maps were scanned, geo-referenced, and classified as suitable for groundwater using ArcGIS 10.4. The methods to assess the potential zone were using weight overlay analysis and hierarchy of analytical process algorithm. The result obtained the potential of ground water were discussed recharge zones into four major categories: very good, good, and moderate and low. This can help for better planning and management the potential resource of groundwater. The results analyzed the groundwater potential that were subdivided in to low, moderate, high, and very high groundwater potentials areas that cover 1664.1,7682.9, 958.27, and 192.78 km2 respectively. The prediction accuracy was checked based on the borehole yield observed and predicted data of respective locations within the selected area.

This makes this fish a very prospect to be developed. Meanwhile, dragon fruit peel is one of the wastes that can be used for diet raw materials and contains vitamins and minerals that have the potential to be useful for increasing growth in fish. This study aims to determine the growth performance of snakehead fed by adding dragon fruit peel flour. This study used test animals, namely snakehead fish juvenile with the size of 1.06 ± 0.02 g/fish. The experiment of fish reared in aquarium measuring of 35cm x 45cm x 90 cm, filled with water as high as 15 cm without aeration. The experiment diets consisted of 5 types, namely feed added with 0% dragon fruit flour (control); 0.5; 1.0; 1.5 and 2.0% of feed. Each treatment was repeated three times. Snakehead was reared for 60 days and fed three times a day on an ad satiation basis. The parameters observed in this study were the survival rate and growth performance of snakehead fish. The results showed that the survival rate between treatments was not significantly different, namely in the range of 97.76 - 100%. Meanwhile, the specific growth rate and feed efficiency of snakehead which added 2% to the diets were the highest, namely 8.66 ± 0.04%/day and 67.83 ± 2.31%/day. The conclusion of this study was the addition of dragon fruit peel flour at 2% enhanced the growth performance of snakehead.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86900267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The participatory ecosystem restoration program at Dangku Wildlife Reserve has had several positive impacts. It is necessary to analyze the influence of the level of perception on the level of participation of the forest encroachers in supporting the participatory ecosystem restoration program at Dangku Wildlife Reserve. This research is survey research with a qualitative approach that uses respondents as a sample of a population with a total sample of 118 respondents. Perception and participation scores were obtained from the classification or category of answers or opinions of respondents to the questions given by the researcher. The scoring of each answer from the respondents is obtained using a Likert scale. The results showed that although the community's perception of the program was classified as good, it was not positively proportional to the participation of the forest encroachers which was classified as moderate. One of the factors that influence this condition is that the benefits derived from the program are not in line with the expectations and needs of the forest encroacher communities.","PeriodicalId":31278,"journal":{"name":"Sriwijaya Journal of Environment","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83435006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
