Abstract: The tofu industry in Indonesia is growing rapidly. The development of the tofu industry is in line with the increasing number of Indonesians population. One of the impacts of the growing tofu industry is the waste produced from the tofu production process. One of the characteristics of tofu liquid waste is that it still contains a lot of organic material. The use of kangkungan plant as a tofu liquid waste processing plant with the phytoremediation method is expected to reduce COD and TSS levels of tofu liquid waste. The purpose of this study was to determine the effect of the number of kangkungan plants on reducing COD and TSS levels of tofu wastewater using the phytoremediation method. Tofu liquid waste used in the research comes from the tofu industry in the city of Malang. This research is using experimental method. The results showed a decrease in COD and TSS levels, where at the beginning COD levels of tofu waste were 5190 mg / l and TSS levels were 3625.70 mg / l. After four months of observation, it was found that COD levels decreased by 1280 mg / l and TSS levels by 487.32 mg / l.

Abstract: The uncontrolled utilization of wetland resources continues to impact negatively on wetland natural resource including plant and animal resources species composition, abundance, diversity and consequently on the ecological functioning of wetlands. This study was conducted to determine resource utilization and management by the local community in Kingw'al Wetland located in Nandi County. Data were collected through descriptive research design. Systematic randomized sampling and use of structured questionnaire, personal interviews, focused group discussions, key informant discussion and field observations were used to characterize utilization and management of resources by the local community.126 questionnaires were administered to households identified by systematic random sampling method within the study area. Data were analysed through frequency distributions, and chi-square. Results indicated......

Abstract: Background: Growing concerns over energy and environmental sustainability have lately sparked worldwide interest in more efficient and cleaner transportation systems and industrial activities. Today's automotive wire harness manufacturing process faces huge challenges in term of competitiveness, quality and responsiveness. The most important is related to environmental issues and how manufactures can produce a sustainable and profitable industry through adopting more environmentally friendly technologies. Materials and Methods: In this article, we emphasize the life cycle assessment (LCA) of a wiring harness in Morocco. An inventory of materials inputs and environmental releases from gate to gate (cutting and assembly processes) was fixed......

Abstract: Background: Predicted changes in air temperatures and/or humidity as part of local climate change have been forecasted to cause occupational health and work productivity concerns. Solid waste collectors are exposed to serious health risks, the most important of which is the risk of thermal stress, while the nature of the climate in the city of Al-Leith is geographically related to it.
Material and method: This study is a cross-sectional descriptive study. To assess the heat stress (WBGT) in the work environment of waste collection workers and identify the use of personal protective devices among solid waste collectors and assess the.....

Abstract: Background:Asbestos, a common element in insulation and building materials prior to the 1970s, was considered an ideal material for use in the construction industry but is today considered toxic waste. The problem with asbestos arises when the fibers become airborne and are inhaled. Because of the size of the fibers, they cannot be expelled by the lungs. They are also sharp and penetrate tissues. The Universities investigated are characterized with old buildings which were built with asbestos materials during the old colonial period in Kenya. This study aimed at assessing asbestos safety, health and environmental awareness among maintenance workers in Public Universities in Kenya. Materials and Methods: The study targeted.....

Abstract: The present study aims at evaluating the effect of environmental factors (Temperature, humidity, Wind) on the transmission of the COVID-19 in different locations of Jammu Division of Jammu and Kashmir, India. The timeline opted was the fall of 2020 (From 5th September 2020 to 5th November 2020). Descriptive statistical measures of all the variables were calculated and Pearson correlation was used to study the association between the variables versus daily number of cases. Significant moderate positive correlation was observed between temperature versus daily number of cases (r-value 0.589, P<0.05), again significant positive correlation was observed between relative.....

Abstract: Collagen is that the main protein of the connective tissue and its molecule is made by three polypeptide strands, named alpha chains. The foremost common motifs within the aminoalkanoic acid sequence of collagen are Gly-Pro-X and Gly-X-Hyp. Collagens are often extracted from the spread of organisms. The utilization of cattle because the main source for collagen has been reconsidered due to the bovine spongiform encephalopathy and transmissible spongiform encephalopathy, while porcine origin collagen is increasingly rejected for religious reasons. One alternative is that the extraction of collagen from marine sources. Sponges, jellyfishes, squids, octopuses, cuttlefishes, and fish offal .....

Abstract: The present investigation produces more thermophilic protease enzymes and it to be applied for various applications. The milk samples were aseptically collected from different areas of Chidambaram in a sterile container. The proteolytic bacteria was isolated and further identified based on morphological and biochemical test indicate that the suspected organisms were Bacillus subtilis. Enrichment culture technique enabled the isolation of strains with proteolytic activity in skim milk agar plates. Among the 10 isolates two isolates Bacillus subtilis (B7) and Bacillus subtilis (B3) showed high proteolytic activity. These efficient two strains were selected for further studies. The efficient isolates of Bacillus subtilis (B7) and Bacillus subtilis (B3) were studied at different optimization parameters ( pH, temperature, carbon source, nitrogen source) and incubation time for the protease production. The maximum protease.....
