Bottom ash is a by-product produced from the process of burning rocks for electricity generation. The bottom ash produced requires a large enough storage area, high transportation costs to move it to a safe final disposal location so that it does not have a negative impact on humans. This research aims to analyze the effect of using bottom ash waste in the HRS WC asphalt mixture. The asphalt mixture is made in the form of a cylinder with a diameter of 101.6 mm and a thickness of 64 mm and is made in a hot mix. The test object was tested using the Marshall test to determine stability. Flow, vim and marshall quotient. The use of 20% BA to substitute sand in the asphalt mixture has a positive impact by increasing the stability value. The flow value meets the specifications required by the ministry of public works and public housing. The VIM value of the asphalt mixture also meets, indicating that the presence of bottom ash with an amount of up to 20% in the asphalt mixture can work optimally in the asphalt mixture.

Polymer Nano-composites (PNC) are efficient materials that consist of polymer matrix and nanoparticles to create a new generation with excellent properties. In this paper a PNC filler-based Zinc oxide (ZnO) is used for enhancing the dissipation factor (DF) or Tan δ of the obtained polymer compared to the individual polymer material and improving the electrical properties of high-density polyethylene (HDPE). The electrical properties of HDPE are investigated under different concentrations of zinc oxide including (0, 10, 20, 30, and 40 wt.%) as well as under different conditions including the variations of temperature (25-150 Celsius) and frequencies (0.1 kHz to 1 MHz). The simulation results reveal that inclusion Zinc oxide as filler can improve the electrical properties of HDPE. In addition to that the minimum value of dissipation factor and the best electrical properties can be obtained at concentration 10 % loading compared to the other concentration levels. Curve fitting solutions were performed to determine the best fit for the experimental results. African Vultures Optimization Algorithm (AVOA) was used to determine the optimal value of zinc oxide filler percentage to obtain the best optimal value of dissipation factor.

Swami Vivekananda was a South Asian visionary and a futuristic thinker of Indian civilization. Science, technology, engineering and medicine in today’s human mankind needs to be re-envisioned and re-organized with the passage of Indian history and the visionary timeframe. Swami Vivekananda always thought of the youth of India. In this article, the author deeply elucidates on Swami Vivekananda’s teaching and its relevance to the futuristic vision of education in free India. Today man and mankind are in the crossroads and crevices of a deep environmental engineering crisis and socio-economic crisis of immense proportions. The author deeply elucidates on the true path of Swami Vivekananda’s teaching in global society and the futuristic vision of the value system of India in post-independence era. The author deeply with cogent and lucid insight elucidates the various stages of development and the progress of free India post-independence India. Surely and veritably a new era in the vast scientific firmament of India will emerge if students, teachers, scientists and policy makers across the globe takes effective steps in the proper application of Global and United Nations Sustainable Development Goals.
