Positive Properties

Millions of tons of waste is produced in the world each year and most of it is not recyclable. Furthermore, recycling waste consumes energy and produces pollution. In addition, accumulation of waste in the suburbs and the disposal of waste are very dangerous for the environment. Using waste material in concrete production is an appropriate method for achieving two goals: eliminating waste and adding positive properties in concrete. Since the green concrete industry is expanding, it is necessary to evaluate concrete that contains waste from all aspects in order to determine its capability. This literature study consists of two parts i.e. the use of waste as a substitute for cement and as a substitute for aggregates. Leading waste material that has been used as substitutes is highlighted and the characteristics of the resulting concrete are evaluated. Among other findings, rubber was found to have improved fire resistance and ductility in concrete and agricultural and PET wastes were successfully used in non-structural concrete, while glass helped to improve thermal stability.

Concrete is the most commonly used construction material in the world over the past decades. But the increase in concrete production leads to an increase in greenhouse gases emission and environmental damage. With the current focus on sustainability, it is necessary to evaluate concretes environmental impact and develop new materials for green concrete. Green recycled aggregates and mineral admixtures are important component materials for green concrete. In this paper, the development of green concrete industry is introduced, and the application of materials for green concrete such as green recycled aggregates and mineral admixtures are discussed.

Billions of waste is produced in the world but the wastes are not properly recycled. Recycling of materials also different issues and it needs more energy. The waste materials are stored in a land also create more amounts of problem and it Leeds to land pollution. The utilization of waste materials in the manufacturing of building is a challenging task. But it is the good solution for disposal of waste materials in the developed building materials. We need to analyze the waste materials first then only we can utilize the materials in the perfect way. Now a day’s lot of research is going on in the waste utilization area. This literature study mentioned the various waste materials and how it is used in our real construction field. The waste utilization gave two things. First one is reduction of the pollution and the second is save the natural materials for sustainable development. This paper also shows the betterment results of the waste utilization technique.

Abstract: The demand of concrete for rigid pavement construction is constantly growing. Thus, the extraction of fine aggregate, coarse aggregate and cement from natural resources also increases. The more extraction of these virgin materials from the natural resources enhances the cost of these materials progressively. Therefore, it has severely affected the financial viability of the government for rigid pavement construction. Further, due to urbanization and industrialization the amount of waste material is also increased. This state creating an ecological problem that must be addressed. Therefore, there is an urgent need to preserve natural resources by using recycled or discarded wastes as a construction material. Hence the main objective of this work is to study of utilization of waste material in concrete production for rigid pavement construction. A four stages methodology is proposed in this study. these stages are (I) Determination of quantity of various materials for development of concrete mix (II) Identification of significant waste materials and their properties (III) Prepare concrete mix using replacement of cement, sand, and aggregate by waste material and (IV) Comparative evaluation of different properties of developed concrete mix. This study to check the suitability of waste foundry sand (WFS), granulated blast furnace slag (GBFS), and waste rubber tyre (WRT) as a replacement of fine aggregate, cement, and coarse aggregate respectively. The analysis and results indicated that WFS, GBFS, and WRT can be used as a replacement of fine aggregate, cement, and coarse aggregate respectively. Thus, it is expected that the proposed methodology will be useful for researcher to determination of suitability of different alternative materials for replacement of cement, fine aggregate, and coarse aggregate Keywords: Concrete mix, Waste Material, GGBS, WFS, WRT etc.

Indonesia is one of many countries in the world so called resource-rich country. Natural resources abundance needs to be managed in the right way in order to avoid dutch diseases and resources curses. These two phenomena generally happened in the country, which has abundant natural resources. Learned from Norwegian experiences, Indonesian Government need to focus its policy to prevent rent seeking activities. The literature study presented in this paper is aimed to provide important insight for government entities in focusing their policies and programs to avoid resources curse. From the internal audit perspective, this study is expected to improve internal audit’s role in assurance and consulting.

Information technology is increasingly developing and has a positive impact on the world of education. The implementation of student counseling with a Knowledge Management System is one of the contributions of information technology in the world of education. Many benefits provided by the Student Counseling Knowledge Management System, in managing the knowledge needed by the counselor section to document student consultations. The development and implementation of a KMS counseling system costs more to employ professional staff to maintain and improve; KMS student counseling application; For this reason, it is necessary to design a Cloud Computing-based Student Counseling Knowledge Management System. The research method carried out in the first stage is to collect data and information about Knowledge Management and Student Counseling, and how to use it to create a Knowledge Management System Application, Student Counseling Based on cloud computing. Furthermore, conducting a literature study and literature review, system design is in the form of data architecture compounding, process design, network design, and user interface design. The design results of this system can facilitate educational institutions in conducting online cloud computing-based student counseling

Abstract. The world is currently facing the covid-19 pandemic which has been shifting most of human daily life by using digital technology. One that was worried about the teenagers spirituality disruption due to excessive use of digital technology. This paper aimed to study the parenetal’s role in the spiritual growth of teenagers during the covid-19 pandemic through a literature study. Through this study, it was concluded that the pandemic period was an opportunity for parents to optimally implement Christian Religious Education in the family due to the large amount of meeting time between parents and teenagers at home. Thus it can be an opportunity for parents to as much as possible improve the spirituality of their teenagers.Abstrak. Saat ini dunia tengah dihadapkan dengan fenomena pandemi covid-19 yang mengalihkan sebagian besar rutinitas manusia dengan menggunakan teknologi digital. Salah satu hal yang dikuatirkan dampaknya terhadap spiritual remaja yang akan merosot karena penyalagunaan teknologi digital secara berlebihan. Tulisan ini bertujuan untuk mengkaji peran orang tua terhadap pertumbuhan spiritual remaja pada masa pandemi covid-19 melalui studi kepustakaan. Melalui kajian ini disimpulkan bahwa masa pandemi menjadi kesempatan bagi orang tua untuk menerapkan Pendidikan Agama Kristen dalam keluarga secara optimal oleh karena banyaknya waktu pertemuan antara orang tua dan remaja di rumah. Dengan demikian hal itu dapat menjadi peluang bagi orang tua untuk semaksimal mungkin meningkatkan kerohanian anak remajanya.
