Abstract

Nanoparticles of a transitional metal oxide such as Copper (II) oxide or cupric oxide have gained considerable interest in the research and development community due to the corresponding conventional materials' extremely different characteristics. Hence, this study aimed at characterizing Copper (II) oxide nanoparticles synthesized through a direct green chemical approach using the outer leafy cover of the maize husk. The fresh maize husk's optical absorption spectrum shows broad peaks that were cantered around 209, 241, and 331 nm, which are the characteristic of flavonoids. The structural analysis shows the formation of Nantokite with a face-centered crystal structure, which has crystalline peaks (111), (220), (311), and (331) at 2θ = 28.5, 47.4, 56.28, and 76.6, respectively. In contrast, the spectrum of Copper (II) oxide showed a base-centred monoclinic crystal structure with lattice parameters: a= 4.688, b = 3.4229, c = 5.1319 and β = 99.91. In conclusion, nanoparticles' synthesis using aqueous corn husk extract was successfully synthesized and characterized. This environmentally friendly approach is a simple, environmentally friendly, inexpensive process and is reproducible.

Abstract

The level of enforcement of road traffic laws plays a significant role in reducing traffic accidents, especially pedestrians, who are more than a fifth of the 1.24 million people killed each year due to traffic accidents. For assessing traffic law enforcement, the registered traffic violation data for the years 2015-2017 were taken from the Traffic Police Department to describe the activities of traffic police personnel in enforcing traffic laws. The violations were categorized into four groups: -those related to driving, vehicle, parking, and others, and Traffic Law Enforcement into safety and other traffic law enforcement activities. The vehicles involved in the violations were categorized as cars, small load vehicles, motorcycles, Bajaj, etc. Traffic Police had registered 77 traffic law violations in the year 2015, 65 in the year 2016, and 86 in the year 2017. Driving violation was the highest registered violation in the three years, and it was slightly higher in 2017. The cars and small load vehicles categories were the highest registered vehicles in several violations within the three years. For motorized two-wheeled vehicles, the highest number of registered violations in the three years was the one related to driving. All vehicle-related and other violations were registered more commonly for cars in 2015 and 2016. Of the registered violations, the parking-related violation occurred only in 2017. Safety-related traffic law enforcement was 89.96% of the total traffic law enforcement activity.

The goals to be completed are identifying land use and transportation conditions, calculating traffic flow, analyzing land use development, analyzing movement generation, and analyzing the effect of land-use change on traffic generation on the corridor of Tallasa City. The research method used in this research is descriptive by identifying the land use and transportation conditions of the Tallasa City corridor. Then carried out an analysis of land use development, analysis of generation and attraction, and analysis of the effect of land use on the generation and appeal of the Tallasa City corridor movement in Makassar City. Based on the analysis results, it can be concluded that the condition of average service level of the existing conditions on the Tallasa City corridor is in category A, with the meaning of stable flow, and the driver is free to determine the speed he chooses. The planned land use pattern in the study area is dominated by land use for housing, education, trade, and services. The type of land use influences the effect of land-use change on traffic generation in the Tallasa City corridor. As a result of this land-use change causes a generation that reduces the level of road services in the planning year, which changes to category C with the meaning of steady flow and speed controlled by traffic.

Abstract

A significant tool for determining how accurate a categorization product is the accuracy assessment. Remote Sensing is one of the essential tools for compiling land use and land cover maps through image classification. The availability of high-quality Landsat imagery and secondary data, an accurate classification technique, and the user's knowledge and competence with the procedures essential to the image classification process. Assess the satellite image classification suitability for further mapping and analysis through accuracy assessments. This paper examined land use and land cover classification using unsupervised classification and extracted NDBI and NDVI further to support main land use and land cover types in the area. The accuracy of classifications was assessed using an error matrix and Kappa statistics. Land use and land cover, NDBI, and NDVI classification accuracies are almost perfect, further verified by the Kappa statistics tool. An excellent unsupervised classification of land use and land cover classes was generated. Accuracy assessment evaluation is one of the most significant tools for determining a classification product's accuracy. The confusion error matrix and Kappa coefficient were particularly useful in calculating accuracy assessment. Typically, accuracy measures of the unsupervised classification show a moderate accuracy level. This study observed almost perfect agreement in all types of accuracy measures. This study is an important source of information that planners and decision-makers may utilize to plan the environment sustainably.

Abstract

Human behavior has a multi-dimensional view of resource utilization; thus, vital to examine the behavior of groups in environmental resource utilization. The group was fishing communities in Kalpitiya Fisheries Inspector Division (KFID). Data was collected through various methods subjected to thematic content-based analysis and statistical analysis. The primary source of income is a fishery where marine fishery and brackish water fishery, along with aquaculture, were the sub-categories. Sixteen percent were engaged in both marine and brackish water fishery. A total of 18116 individuals were marginalized in the area. Un-sustainable resource utilization has decreased the area's existing resources, particularly for Internally Displaced Persons (IDPs). Their behavior has created specific environmental problems in Wannimundalama and Manadalakuda. Though education level was not satisfactory (96%), the statistical analysis showed dis-concordant status; neither education nor the source of income affects their poor behavior in resource utilization. Comparing two fishing harbors illustrated that the cultural aspect also affects the behavior. The perception of environmental protection is also poor, IDPs. Gender vice behavior reflected that females are more willing to protect and restore the environment than males. Findings illustrated that the dimensions and categories of the system directly do not decide the behavior of groups in environment resource utilization. Environmental communication is essential and positively impacts human behavior in environmental resource utilization. The study recommends investigating the factors constraining sustainable resource utilization behavior in KFID, emphasizing the necessity of environmental communication.

Abstract

The construction industry is challenged with project risks often resulting from cost estimating uncertainties. Previous research shows that 50% of construction disputes are estimating-risk related, leading to poor project performance. This study investigated the effects of charge evaluating risks on project cost overrun and resultant claims to improve project efficiency. The investigation was carried out using well-structured questionnaires addressed to construction professionals in Imo state to determine the critical cost estimating risks and identify principal evaluating risk-related claims contributing to cost overrun in construction project delivery. The results reveal that design issues (design complexity, preliminary design, and design errors) are the key contributors to cost estimating uncertainties. Inadequate cost data, estimator's expertise, and omission in contract documents are the principal causes of evaluating risk-related claims in construction projects. The study concluded that the inaccurate estimation of construction costs eventually leads to claims and cost overruns in the delivery of building projects. It's possible that the risk involved in cost evaluation is to blame for this. Estimators with sufficient efficiency, skill, and experience should be included in estimating to increase the likelihood that the estimates will be close to correct. The study recommends the availability of concise designs and specifications and details as well as updated market surveys to eliminate uncertainties and improve cost data before estimating a construction project.

Abstract

The dimensions of the road affect the flow of traffic passing over it. Even though the traffic lanes are the same width, the traffic flow will not be the same because the environment is different. This study aims to determine traffic conditions and characteristics through density analysis and the level of traffic service on the roads. This research is a type of non-experimental research, like a case study with survey methods and direct field observations to determine the performance of the road network. The primary data collected through direct recording in the field is the number of vehicles passing through Perintis Kemerdekaan Road and observing the side constraints that reduce capacity and service levels and impede smooth traffic flow. Data analysis used the Highway Capacity Manual (HCM) and Indonesia Road Capacity Manual (MKJI) 1997. The service level value (LOS) is obtained by dividing the peak traffic volume in the west direction of 4728 PCU/hour with the road capacity value obtained by the service level of 0.89 entering category E while in the east direction with a traffic volume value of 4974 PCU/hour obtained the degree of saturation value of 0.94. The results of the study show that the level of road service is between (D - E) with a value of 0.85 to 1.00, which means that it is close to road capacity and sluggish speed, high traffic density due to internal barriers and vehicle drivers who experience traffic jams of medium duration.

Abstract

Environmental awareness is crucial in addressing the issues of plastic waste and pollution, which have a significant impact on our environment and our health. The study aimed to analyze the awareness of Bulacan State University College of Science Generation Z students regarding PLAF (Plastic Flamingo) and other campaigns related to plastics in online shopping. The researchers used a descriptive research design to achieve this goal and collected data from 350 samples of Generation Z students through a standardized questionnaire distributed via Google Forms. The findings revealed that Shopee is the most commonly used online shopping application by students, and they tend to purchase items online when needed. Bubble wrap emerged as the most frequently used parcel packaging material. The results also indicated that the students are highly aware of the different impacts of parcel packaging, as evidenced by the mean score of 4.02. However, their awareness of environmental campaigns related to plastic was only average, with a mean score of 2.93. In particular, the understanding of PLAF (Plastic Flamingo) was low, with a cumulative mean score of 2.13. The findings suggest the need to improve Generation Z students' awareness of environmental campaigns and promote ecological practices and involvement in addressing plastic waste and pollution issues. Educating and engaging students through various campaigns and initiatives can help raise their awareness of the environmental impacts of plastic waste and encourage them to adopt sustainable practices in their daily lives.
