    Analysis of the Physical Properties of Solid Waste from Three Different Buildings.
    (Daffodil International University, 2025-07-09) Ahamed, Rabbi; Haque, Md. Rubel
    This study examines the physical characteristics of solid waste—namely moisture content and bulk density—produced in three specific locations at Daffodil International University: the Civil Engineering Building (A1), Yunus Khan Scholar Garden 2 (A2), and Food Court 2 (A3). The study seeks to evaluate the impact of these physical factors on suitable disposal options and to propose location-specific waste management procedures. Waste samples were collected over a ten-day period and analyzed using normal laboratory protocols to ascertain moisture content using oven-drying methods and bulk density based on mass-to-volume ratios. The results demonstrated considerable diversity among the three locations. A1 produced primarily dry, recyclable trash with an average moisture level of 12.7% and modest bulk density. A2 demonstrated the greatest moisture content (47.7%) and bulk density (194.7 kg/m3), owing to the substantial quantity of food and organic waste. A3 generated heterogeneous trash characterized by intermediate moisture content and low density, indicative of the impact of food packaging and plastic use. The research advocates for a zone-specific waste management strategy: recycling for dry academic trash, composting for organic residential waste, and integrated treatment for mixed commercial garbage. This research highlights the significance of defining physical waste characteristics to develop efficient, sustainable, and economical disposal systems in institutional environments. The results demonstrated considerable diversity in the physical composition of garbage and underscored the elevated moisture content as a constraining factor in conventional landfill and open dumping practices. This paper advocates for incineration as a feasible and energy-efficient method for garbage disposal, particularly appropriate for the regulated institutional setting of a university. Incineration provides a sustainable solution to waste management concerns in private institutions by optimizing energy recovery and minimizing landfill reliance. The paper closes with actionable recommendations for the implementation of an incineration- based system and advocates for regulatory assistance to guarantee environmental compliance and energy efficiency.

    A Study on Traffic Volume and Composition at Dhanmondi 32 Intersection
    (Daffodil International University, 2025-08-03) Hossain, MD Parvez; Hasan, MD Roman; Mostary, Shamima
    Traffic congestion is an important problem in urban regions especially in areas with high traffics like congested junctions where different means of transport interact. This research is about the traffic volume and composition at one of Dhaka, Bangladesh most important junctions, that is the Dhanmondi 32 intersection. The research will determine flow patterns of traffic as well as distributions of vehicles and the levels of congestion with a view of identifying the factors that affect mobility. Data was collected through manual traffic counting and video analysis over multiple time slots, covering peak and off-peak hours. The study groups vehicles under private cars, motorcycles, buses, rickshaws, bicycles, and freight vehicles, examining their contribution towards congestion. Results indicate that private cars and motor cycles during the peak hours (31-34%) and during off-peak hours (26%) dominate the traffic situation. Non-motorized vehicles, rickshaws and bikes contribute more to the situation of delays during the off-peak hours than the actual off peak hours. Although public buses have an important role to play, they are not usually characterized by proper stop management that further aggravates the congestion. Important issues of traffic are identified in the study, namely, inefficient signal coordination, lack of special tracks, as well as uncontrolled movement of pedestrians. From the findings, recommendations include making dedicated lanes for motorcycles and non-motorized vehicles (NMVs) having optimized signal timing, having designated bus bays, and improved pedestrian infrastructure to make the roads efficient and safe. This research is data-driven to guide urban planners, policymakers, and administration in charge of traffic in the city life as to how to decongest and enhance mobility at the Dhanmondi 32 intersection. Adoption of the proposed measures can help create a more disciplined, secure, as well as efficient urban transportation in Dhaka.

    Observation Of Drinking Water Quality Parameters of Selected Area Nearby Daffodil Smart City
    (Daffodil International University, 2024-02-18) Salman, Shaykh
    The fundamental requirement for good health and a fundamental human right is access to clean drinking water. It has a close connection to both the economy and the health of the country. Water contamination can harm people's health in a variety of ways. Vomiting, diarrhea, kidney, liver, and stomach cramps are a few of the most common health problems brought on by drinking water. This investigation's goal was to select an area with drinking water quality. I took thirty water samples from three different places: Khagan Bazar, Dattapara, and Changaon, Each sampling area contains ten separate sampling points. The physicochemical properties of the samples were odor, temperature, pH, turbidity, iron, dissolved oxygen (DO), and biological oxygen demand (BOD). All the evaluated characteristics were compared to domestic and international drinking water quality standards to ascertain the study region's overall drinking water quality status. The pH range for standard drinking water has been determined by my research in the Khagan Bazar, Dattapara, and Changaon yielded data that fell within this range. The outcomes for Changaon, Khagan Bazar, and Dattapara, however, some point fall outside of this range. Here, we can observe that the pH levels of the local water are quite near to the average. Additionally, some of the BOD readings from our testing in Khagan Bazar, Dattapara, and Changaon met the requirements. BOD levels in a few different samples were higher than usual. Other parameters EC, Turbidity, Iron, Temperature, DO, and Odor satisfy the drinking water quality.

    (Daffodil International University, 2024-07-06) Shuvo, Faysal Ahmed; Sakib, Sadman
    The capital of Bangladesh is Dhaka, bears the title of being the world's most denselypopulated city. As of 2022, the population of Dhaka was 10.2 million, and Greater Dhaka has about 22.4 million citizens. Dhaka faces the constant challenge of escalating congestion, particularly in its roadways. The city’s infrastructure struggles to cope with the increasing vehicles, resulting in extensive traffic jams. Contributing factors include faulty traffic signaling systems, insufficient personnel, limited road space, and aggressive driving habits. These traffic congestions adversely affect our health. To address this issue the government could consider various solutions such as constructing roads to improve east-west connectivity within Dhaka, putting in place a system of grade-separated roads, launching a BRT system, and creating a Metro-Rail system. By all evirating traffic congestion, Dhaka can play a significant role in enriching a healthier environment free from noise and pollution, thereby enhancing the quality of life for its residents.

    A Review on the Utilization of Rice Husk Ash as Admixture in Concrete
    (Daffodil International University, 2024-07-15) Roy, Tithi; Hossain, Fihad
    To evaluate the usage of rice husk ash as an additive in a typical setting, the effects of adding RHA to concrete grades 20 and 30 at 0%, 5%, 10%, and 15%, respectively, are determined. The recovered husk was sun dried, screened, and burned in an incinerator set at 400 degrees Celsius. After cooling and passing through a 425μm screen, the ash wasadded as an additive during mixing. Both grades of concrete were mixed, and both fresh and hardened concrete's characteristics were evaluated. The CS of a cylinder of RHA concrete samples that were curing in water was measured at 7, 14, and 28 days, respectively. The findings demonstrated that, for both concrete classes, the slump of RHAconcrete increases as the percentage of RHA added increases. The addition of 5% and 10% RHA, respectively, increases the cs of samples of both concrete classes cured in water; however, the strength gain was greater with the addition of 5% RHA. 15% addition of RHA lower than others two percent of addition of rice husk ash
