Abstract

Drought is one of the impacts of climate change, which affects agriculture's productivity and, eventually, farmers in Afghanistan. Afghanistan has a typical inland continental climate with considerable temperature and precipitation variation between seasons. A considerable part of Arabmazari's village relies on irrigation for agriculture; however, with the low precipitation, temperature rise, and surface and groundwater depletion, farmers experiences drought. The objective of the research is to explore the vulnerability and coping capacity of the farmers of Arabmazari village to drought. The research considers a non-probability purposive sampling method. The data was collected from 3 members of the Ministries through interviews and from around 30 farmers through FGD and questionnaires. The research adopts descriptive and correlational statistics to assist with the qualitative and quantitative nature of the study. The research finds that farmers are generally highly vulnerable to drought impacts. With the government's lack of facilities, financial capacity, and absence of mitigation and preparatory measures, farmers are forced to rely on their own, often ancient, methods to plan and survive drought. Some coping strategies for crops and livestock included cultivating drought-resistant crops, changing cropping patterns, practicing crop rotation, soil treatment, and providing supplementary feeds for animals. Non-farm coping strategies were selling/pledging assets, migration, seeking employment elsewhere, dropping out of school, and seeking humanitarian aid. The government intervention was only through drought relief, which was ineffective in the long run. It is recommended that the government intervention adopt more effective mitigation and preparatory measures. Moreover, a thorough research/survey is to be done to find out the responsibilities and contribution of the Water Association Committee of Chamtal district towards the farmers of Arabmazari village. Currently, a cost-effective and immediate adaption is a practical option for the farmers, such as GIS, to create a localized map of the drought-prone areas.

Abstract

The issue of electronic goods and the pollution they generate is a rapidly growing global concern. These are regarded as any appliances using an electric power supply that has reached their end-of-life. They contain various components, some of which contain harmful substances that cause risks to both human health and the environment. Due to rapid economic growth, urbanization, and increased consumer demand, the manufacturing and usage of electronic devices have a significant increase on the annual growth rate of 5% to 8% compared to other solid wastes. It is in this context that this research aims to assess the awareness and knowledge levels of e-waste pollution, as well as the handling practices and attitudes towards e-waste among residents of Kigali City, Rwanda. The study took place in three districts of Kigali City: Gasabo, Nyarugenge, and Kicukiro, where data were collected using a questionnaire survey administered to a sample of respondents (n=204) living in the city of Kigali. Statistical data analysis was applied on the analysis of the collected information determining the significancy. The results indicated a limited awareness of e-waste pollution among electronic users and identified significant health risks faced by workers and repairers of electronic devices. Thus, a low level of knowledge, noticeable prevalence of inadequate e-waste pollution practices and absence of regulations and legislation concerning e-waste and recycling activities was also identified as a problem. Therefore, educating individuals, raising awareness, and promoting environmental concern implementing the three "Rs", reduce, reuse, and recycle to maximize re-source efficiency and material utilization needs to be enhanced.

Abstract

Food industry is one of the most crucial and rapidly growing economic sectors in Indonesia. One of the examples is the food jam industry. This industry was located in Tangerang, Indonesia. The majority of the food jam industry uses its own source of water, so this part is also important to water producers in Indonesia. Water used in the food jam industry should meet the requirements of at least drinking water quality, so the factories need to treat the water. Good quality water is water that requires good physical, chemical, and bacteriology properties. Hard water is a term known for water that contains a high concentration of minerals such as Calcium (Ca) and Mag-nesium (Mg). Moreover, water with very high degrees of hardness is harmful to health. In this study, we want to evaluate and determine the pH, total hardness, and total dissolved solids (TDS) at three different times namely morning, midday, and afternoon. The results obtained in the range of pH analysis are 6.98 to 7.99 with all cover times. The total hardness in the boiler water and the TDS are around 252.6 to 388.2 mg/L and 310 to 406 mg/L, respectively. These results indicated that it has fulfilled the requirements for total hardness values under the Minister of Health Regulations (Permenkes) No. 492/Menkes/Per/IV/2010.

Abstract

POME is a kind of liquid waste produced by the crude palm oil industry. POME was not treated adequately, resulting in an issue for the environment owing to excessive levels of COD and BOD. Algae is a kind of bio-absorbent that may neutralize contaminants in liquid waste. Microalgae need carbon, nitrogen, and phosphorus-containing ingredients to flourish. These nutrients are necessary for photosynthetic carbon sources to be converted into biomass. POME includes a high concentration of C, N, and P; hence this research aims to investigate the potential of POME as a medium for the development of algae such as Spirulina, Nannochloropsis, and Chlorella. The experiment was carried out by varying the nutrients, water type, and time of nutrient feeding. Urea and sodium bicarbonate were the nutrition. Preparing the medium, culturing the microalgae, assessing biomass, counting the algae cells, and creating a calibration curve were the procedures in the experiment. The findings revealed that POME is the best medium for microalgae, that Spirulina grows better in POME than Chlorella and Nannochloropsis, and that providing nutrients every 2 days was better than introducing nutrients at the beginning and without adding nutrients.

Abstract

The use of clean water around the world continues to increase along with the increase in population and is increasing when the whole world is hit by the COVID-19 pandemic. Therefore, research is carried out to treat greywater waste effectively in a simple and inexpensive way. The method used in this study is a single method, namely filtration (a mixture of soil and sand, activated char- coal and gravel), Lepironia articulata and a combination of the two methods, namely constructed wetland subsurface vertical flow. The results of this study showed a decrease in BOD and COD levels reaching 97%, 88% phosphate, 18% pH and 95% MBAS in the constructed wetland. This is due to the synergistic interaction between plants, media and microorganisms in removing pollutants effectively. This research needs to be developed further and explore the capabilities of each constructed wetland element, especially the Lepironia articulata.

Abstract

Charcoal remains the main energy cooking source for urban dwellers in Uganda. The Shea Nut tree produces quality charcoal which is efficient and locally made. Therefore, it is facing increasing threats from the local communities so as to meet the mushrooming demand. The study analyses the state of the Shea Nut tree, drivers of charcoal production, predict Shea Nut tree vegetation coverage, and establish mechanisms for sustainable utilization and conservation of the Shea Nut trees in Kapelebyong District. Landsat images were classified using likelihood classification in ArcGIS and interviews were conducted whilst geospatial, Stata, and Nvivo tools were used for analysis. The findings reflect a sharp declining trend in the coverage of the shea Nut trees by 2.3% and 6% from 2002-2012 and 2012-2022 respectively. The major drivers include high demand from urban areas, the need for income, and unemployment. As a result, it is predicted that by 2032, the coverage will have reduced to only 713 hectares (7.3%) from 1277 hectares (10.6%) in 2022. Therefore, charcoal production with other land uses has greatly resulted in Shea Nut tree deterioration. The study recommends the use of alternative energy sources, the provision of alternative income-generating activities for the local communities, Government of Uganda through NFA needs to enforce the ways through which Shea Nut trees are managed and utilized in order to minimize illegal cutting.

Abstract

Smaller size plastics known as microplastics are harmful for marine biota as well as humans. One of the common methods for the removal of microplastics from water is coagulation. Chicken eggshells and chitosan are two natural ingredients which contain useful content for the coagulation process. Therefore, this paper describes the effect of concentration of eggshells and chitosan as coagulants in the separation of microplastic from water using RSM (Response Surface Methodology). The effect of tannic acid concentration as coagulation aid was also analyzed in this paper. The coagulants were varied with concentration of 1.5-8.5 g/100 mL and tannic acid concentration was 3-17 mg/100 mL. The result of this study showed coagulation with the highest efficiency occurred when 8.5 g/100 mL of chicken eggshell coagulant (89.14%) and 10 g/100 mL chitosan coagulant (75.67%) was added. Optimum operation occurred after the addition of coagulant aid in the amount of 7 mg/100 mL with chicken eggshell and 15 mg/100 mL with chitosan.

Abstract

Indonesia and Malaysia are recognized as the world's leading producers of palm oil. Along with the growth of the palm oil industry in Indonesia, the amount of Palm Oil Mill Effluent has increased. Palm Oil Mill Effluent (POME) is a liquid byproduct of the palm oil production process. POME has been treated using aerobic and anaerobic ponds to lower Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels, but it still includes nutrients like as C,N,P that are beneficial to the development of microalgae. On this study, Spirulina platensis was grown in POME medium with 20%, 40%, and 60% V. concentrations. Every two days, the nutrients Urea, NaHCO3, and TSP were administered. Seven days of aeration and 24-hour lights are used throughout the cultivation phase. The results indicate that POME with a 20 % concentration is the optimal medium for plant growth. Add 25 ppm Urea, 50 ppm TSP, and 200 ppm NaHCO3 for the optimal nutritional composition. At the same treatment on various medium, the highest growth rate of Spirulina platensis is determined to be µ = 0.128% per day, with an optical density of 0.648. Carbon reductions range from 83.03 % to 84.10 %, while Nitrogen savings range from 78 % to 79.55 % when POME is used as a growing medium. This study also shown that the C, N, and P concentrations of POME fall by 93 to 98 %, 99 to 99.5 %, and 92 to 97 %, respectively.

Abstract

Each year plastic production worldwide has increased. Approximately 10% of the production of plastic will lead to the sea. This plastic is degraded to be a small particle size < 5mm called microplastic. The river is the main route of entry of plastic from land to the sea. Sayung River is a river that has the potential to be contaminated with microplastics around which it is used as a location for the cultivation of various fisheries commodities including Pernaviridis, Penaeus monodon, and Lates calcarifer. The study aims to determine the number and type of microplastic in Penaeus monodon, Pernaviridis, and Lates calcarifer. Samples were taken from three different stations in the coverage area. Microplastic abundance analysis by isolating microplastic on each sample. Isolation samples of Pernaviridis, Penaeus monodon, and Lates calcarifer are done by dissolving the sample in a solution of 10% KOH was allowed for 24 hours at a temperature of 60 oC and observed under a binocular microscope. Founded types of microplastic are fiber, fragments, pellets, and films on Pernaviridis, Penaeus monodon, and Lates calcarifer. Pernaviridis found on many types of films, in Penaeusmonodon are the most prevalent types of fragments and the Lates calcarifer most common types of fiber. Pellet type is the least kind found in Pernaviridis and Penaeus monodon. Based on the age when taken, Penaeus monodon is the commodity that has the most potential to be contaminated with microplastic while based on the number of particles found in Lates calcarifer is the commodity with the most potential to be contaminated with microplastic.

Abstract

Vernonia guineensis Benth. (Asteraceae), locally known as ‘African ginseng’, is an herbaceous plant with various therapeutic properties, sold by herbalists, and used in several traditional African preparations. Nanosizing has the capability to potentiate those preparations in their pharmacological properties. Premilling and extensive grinding using a planetary ball mill were used to reduce the size of V. guineensis tubers towards antioxidant studies. Water was used as an environmental friendly, cost effective solvent and dispersant to generate a nanocolloidal suspension of V. guineensis tubers. Size and size distribution were determined via photon correlation spectroscopy at room temperature which allows discussion on stability by Zeta potential and polydispersity index. Phytochemical screening shows presence of alkaloids, coumarins, polyphenol, saponins, tanins, terpenes, and anthraquinones. The distribution curve in water shows a polydispersed system with large hydrodynamic particles of size close to 1000 nm and a Z-average of 484.5 nm. The preparation separate in two phases with polydispersity index 0.217 for the supernatant and 0.543 for the suspension. In the supernatant and suspension, the particles zeta potential were -12.3 mV and -13.7mV respectively. The Mastersizer analysis indicates that there are smaller particles in volume in the supernatant than in the suspension. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity shows an increase in antioxidant activity, compared to that of ascorbic acid, in the nanoformulated state. These findings allow us to conclude on the potential of size reduction when compared to solvent extraction in pharmacologic preparations.
