Abstract

Harjamukti Village is located in Depok City which is a buffer zone for the capital city of DKI Jakarta, the rapidly growing housing sector shows that this location has an attractiveness. The next problem that arises is the potential for noise from vehicular traffic due to community mobility. Noise measurements carried out using SNI 8427: 2017 show the LSM value on each road: Tumaritis Road (68.87 dBA), Bungur Road (61.29 dBA), Putri Tunggal Road (73.67 dBA), Putri Tunggal District Road (65.7 dBA) and Sementara Road (61.29 dBA). This study was conducted to see the road class based on the noise and capacity parameters, so that from these two parameters, can we clearly show the road class being analyzed. The measurements were carried out for 24 hours using the standard SNI 8427: 2017. The quality standard for the residential area used was 55 Dba based on the Minister of Environment Decree No. 48 of 1996. The road capacity used is analyzed based on the number of vehicles and the class of each road. Based on the noise parameters (sig 0.006) and capacity (sig 0.000) so that from the noise parameter there is no significant difference in the 5 research locations, while the road capacity shows a significant difference from the 5 research locations. Prediction of road class cannot be determined from the noise value and road capacity, because the noise obtained needs to be analyzed for the types of activities around whether there is an influence from other activities that are also dominant, such as toll roads and road capacity, because there are local road classes whose capacity is not detected different from collector road class.

Abstract

The study was conducted to evaluate the management of domestic solid waste in Cai Rang district, Can Tho city. The study conducted sampling of domestic solid waste from 20 households in four wards Le Binh, Hung Phu, Ba Lang, and Tan Phu within 07 days from March 6 to 12, 2023. At the same time, three groups of subjects including 120 households, 3 Environmental Managers, and 3 employees of Urban Environment Joint Stock Company were interviewed to collect information. The result showed that the average domestic solid waste generation coefficient reached 0.28 kg/person/day, and the amount of domestic solid waste generated can reach about 11,027.3 tons by the end of 2023. Of which, up to 91% of the volume of domestic solid waste was recyclable, including 52% of biodegradable organic waste, and 39% of recyclable waste. As for domestic solid waste management, there was still a limitation in classifying waste at source, this rate only fluctuates between 43.4-86.7%. Besides, the rate of households registered for domestic solid waste collection service had a difference between urban and rural areas, fluctuating from 76.7-96.7%. After being collected, domestic solid waste was transported to the Can Tho household waste incineration plant (EB plant). Meanwhile, the remaining amount of domestic solid waste was treated using unsanitary landfill methods, and thrown into rivers, causing environmental pollution, and public health. Although propaganda activities related to domestic solid waste management were carried out in four wards in Cai Rang district, Can Tho city. However, the level of implementation of these activities was not regular. From that, the study identified a number of difficulties in domestic solid waste management, including solid waste that was not completely classified at source, and garbage collection services that were not organized throughout the area. The district lacked specialized waste collection vehicles after classification, and public propaganda, and education work were limited. This research will help local authorities come up with specific solutions to improve the quality of solid waste management in Cai Rang district, Can Tho city.

Abstract

Native fodder and fruit species provide various products and services to local communities besides their fruit (food) and fodder supply in our country including in the study area. Although, there is rich traditional knowledge on propagation methods of native fodder and fruit species and their local use, but little recognition has been given by forestry research and extension efforts to enhance them. The general objective of the study was to investigate the use value and propagation methods of native fodder and fruit species in the Merhabete district, Ethiopia. A total of 127 households were randomly selected and interviewed about local use and propagation methods of native fodder and fruit species. The study indicated that the majority of native fodder and fruit species were used for firewood (23.9%) followed by charcoal (10.9%), timber, and construction wood (10.6%), fencing (9.3%), soil fertility improvement (9.1%), farm tool (7.1%), and medicine (3.3%). Native fodder and fruit species (42.7%) were propagated through wilding (natural regeneration) and the remainder were propagated through seedlings (7.2%), seed (6.06%), and stem cutting (4.8%). Overgrazing (46.5%) followed by overexploitation (22%), climate change/drought (20.5%), and disease and pest (11%) were the major regeneration constraints to native fodder and fruit trees/shrubs species in the study area. Therefore, proper involvement either through research or development works are essential to reduce the propagation constraint of studied species. Ziziphus spina-christi (L.) Desf. followed by Faidherbia albida (Delile) A. Chev., Cordia africana Lam., Ximenia americana L., and Acacia senegal (L.) Willd. were the most preferred species for planting by farmers in the study area. Domestication should focus on the preferred top five species to promote species conservation and sustainable use.

Abstract

Heavy metals are the main pollutant substances in the environment. Heavy metals are a type of metal with high density and are very dangerous to living organisms, especially humans. Living organisms can adsorb the bioaccumulative and sedimentation of heavy metals that settle in water. Some compounds which found in wastewater including Cadmium (Cd), Copper (Cu), Iron (Fe), and Lead (Pb). These heavy metals cannot naturally degrade, additional processing is required before it being released into the environment. To prevent environmental pollution impacts, wastewater containing heavy metals must be handled properly and optimally. One method that can be applied for wastewater treatment is degradation by photocatalysis, utilizing the assistance of light. This research is to investigate the effect of pH and irradiation time on the degradation of Cd (cadmium), Cu (Copper), Fe (Iron), and Pb (Lead) heavy metals. To enhance the photocatalytic activity, the synthesis of ZnO-Zeolite nanocomposites was conducted. The ZnO-Zeolite nanocomposites produced were analyzed by SEM-EDX and XRD. The utilization of ZnO-Zeolite nanocomposites is deemed effective in reducing heavy metal concentrations. The degradation with Ultraviolet (UV) light exposure runs within 15-120 minutes with pH variation between 4-8. The degradation of heavy metal runs at 60 minutes and 120 minutes showing an optimum percentage removal of metals approaching 100%. The optimum pH values for Cd, Cu, Fe, and Pb are pH 8, pH 7, pH 6, and pH 8, respectively. The sequential metal degradation percentages are 98.96%, 95.43%, 96.07%, and 95.53%, respectively.

Abstract

This study used a novel method to transform rice husk waste into a highly effective and specific adsorbent for several dyes, including malachite green, direct yellow, congo red, and rodhamine B. The rice husk was analyzed and used for the purpose of eliminating these colors from water-based solutions. The adsorbent exhibited excellent heat stability, and the sample retained the functional groups of lignin. The parameters pertaining to kinetics were also examined. The adsorption exhibited a time-dependent rise and reached its peak after 100 minutes. In the kinetics tests, the most suitable model to characterize the behavior was found to be the pseudo-first order, with a regression value near to one. The rice husk shown significant potential and selectivity in the removal of malachite green and rodhamine B, particularly in the presence of direct yellow and congo red, from aqueous solutions.
