    (K.K.Wagh Institute of engineering education & research, 2019-06-08) Khan, Tabrez; Magar, Rajendra; Ansari, Zakir; Shaikh, Afzal
    Academic audit is a methodical and scientific process of designing, implementing, monitoring and reviewing the quality in academic systems in higher education. The academic audit provides a strategic planning and its implementation for the teaching learning activity in the institute. In order to ensure quality and effective curriculum delivery, in teaching-learning, quality assurance system like Internal Academic Audit (IAA) system is very much essential. This paper aims to discuss the effective implementation of IAA in the technical campus situated in Panvel, Maharashtra. Academic Audit is done thrice during the term as Pre Term Audit- before the commencement of the term, Mid Term Audit- during the mid of the term and Post Term Audit- after the term end. Total thirty four numbers of input parameters are identified based on which academic audit is carried out. For every single parameter in the audit format, the course owner is evaluated for complete, partially complete and incomplete status of that parameter as per defined rubrics.The score of all the parameters is converted to a scale of 5 which would become the score of that course owner and would be used for appraising the concerned course owner.The reports of the Pre Term, Mid Term, and Post Term audit would be kept with the audit team and the necessary corrections would be conveyed to the respective course owners at the time of the audit. It was observed that after the introduction of the aforementioned process, the academic files of all the faculty members were found complete in all respects and quality of assignments, teaching learning and evaluation process was improved significantly.

    Automatic floor cleaner is a system that enables cleaning of the floor by the help of highly stabilized and rapidly functionalized electronic and mechanical control system. Current project work targets to use automatic floor cleaner for large floor in house-hold purposes and office floors. The cleaning purpose is specifically carried out by continuous relative motion between a scrubber and the floor surface. During the cleaning and moving operation of vehicle a propulsion mechanism such as driven wheels and guide wheels for the dry tracking on the floor surface to be cleaned, suction of water is carried out by vacuum pump, scrubbing action is done by the scrubber directing water towards rear end. Preferably, a sweeper mechanism is mounted on the body forwarded by propulsion mechanism and operated with such control system for advance sweeping of a debris-laden floor surface. A PID controller is used to govern the motion of system which takes the input from sensor circuit and feeds it back to microcontroller which gives rise to the simulation of wheel in a synchronized manner. The new automatic floor cleaner will save huge cost of labor in future. The basic advantage of this product is that it will be cost effective and no human control is needed. Once put in on mode it will clean the whole room without any omission of surface.

    In this work, chemically treated wheat straw fibres were used to reinforce polymer Polypropylene in order to ascertain the effect of the treatments on the mechanical and water absorption properties of the composites produced. Wheat straw fibre was first extracted from its husk by soaking it in water and was dried before it was cut into fibres form. It was then chemically treated in alkali solution of sodium hydroxide (NaOH) and potassium hydroxide (KOH) in a shaker water bath. The treated wheat straw fibres were used as reinforcements in polypropylene matrix to produce composites of varied fibre weight and random fibre orientation were used. Tensile and flexural properties were investigated using universal testing machine while water absorption test was carried out on the samples for 24 hours. It was observed from the results that, NaOH treated samples gave the best tensile properties while KOH treated samples gave the best flexural and water repellent properties.

    Design and development of high strength paper bag using non-recycled paper
    (AIKTC, 2016-05) Ansari, Zakir; Thakur, Altmash (13ME140); Shaikh, Mohd. Rafi (12ME52); Sayyed, Arbaz (13ME137); Khan, Mohd. Shaahid (12ME35)
    The detrimental effects of plastic bags on the environment are well known. It is now appropriate to use alternative materials for manufacturing bags and in packaging industries. While biodegradable plastics research has gained steam in the first world countries, countries like India are still dependent upon cheaper alternatives such as Kraft paper/ old newspaper (ONP) as packaging materials for transport. Recycling of paper to produce bags is very common but it has its own disadvantages. The best option is to reuse. Every year lacs of papers are collected in academic Institutes in the form of assignment and practical papers with which paper bags can be produced. This option is very good in terms of economic viability. Further, the cost of these bags can be reduced by adopting appropriate materials in manufacturing. The design of the bag conforms and is much more than the expected load carrying capacity of a bag whether plastic or paper of the same size. Striking a balance between the strength and cost of the bags requires extensive experimentation using different designs and materials used for gluing and handle. Design of experiment using software Minitab helped to optimize the experiment results and deduce the best combination therefrom. The design of machine for manufacturing these paper bags is based on the design selected from this analysis. In order to reduce the dependence on plastic bags in our day-to-day life, it is very important to achieve desirable factors such as strength, durability and affordability in paper bags. In future mass production by establishing a centralized unit for our as well as nearby Institutes can help to further reduce and provide sponsorship to this project.

    (AIKTC, 2016-05) Ansari, Zakir; Pawle, Kashif (13ME135); Shaikh, Mohd. Badrul (12ME53); Naik, Vivek (12ME38); Mulla, Umez (12ME37)
    Plastic, although considered as one of the greatest inventions by virtue of its use in carrying things but has become a major element in polluting the environment. Plastic bags are known for their carcinogenic gas release after burning in air, for choking of sewage lines during monsoon season and the harmful effect on aquatic life. Government is promoting the use of paper bag to reduce plastic pollution. The project aims at designing a model of paper bag manufacturing unit, which would manufacture paper bags from A4 size educational sheets also commonly known as assignment papers (21.7 X 28.8 cm). The assignments which each student write during his academic year are used as raw material for our manufacturing unit. The paper bags are designed by taking into consideration it’s cost, load carrying capacity and aesthetics. These paper bags have been tested at standard conditions and were found to have enough strength to replace plastic bag of 20 micron (10 X 14 cm). This project is based on reuse of papers for manufacturing paper bags instead of using recycled papers. It also aims on switching traditional manual method of paper bag manufacturing to low cost semi-automated system in order to achieve the goal of mass production of paper bags through automation. The motive behind doing this project is to manufacture paper bag which are easily disposable, cause no harm to environment and replace the current trend of using plastic bags in India.

    Efficient data storage and retrieval system using own cloud for higher education institutes
    (K.K.Wagh Institute of engineering education & research, 2019-06-08) Ansari, Zakir; Khan, Tabrez; Syed, Kaleem; Syed, Shariq
    In institutes of higher education, record keeping and its retrieval has always been a problem. Often it is required that the same documents which originated from a common source are to be used by multiple users at different places for different purposes. This puts forward multiple challenges ranging from timely retrieval to data security. To overcome all such issues, a safe, secured,updated and efficient retrieval system is installed, configured and maintained at the institute level using open source cloud software called Own cloud. The user groups have been created program-wise. Then the user accounts are created for every faculty and added to specific program group. A directory structure has been created considering the common ministrative and teaching-learning requirements of the programs. This structure has been shared with all the faculty members of the respective program. A write access or read access is provided to all the concerned users through which each user has required access on fly. Every faculty user has 1 GB quota and department clerk has 10 GB quota, which can be used to store individual's teaching-learning and administrative records. Such implementation has provided an immediate and efficient access to all the teaching-learning and administrative records at any point of time and any location.

    (Paper Presented @ International conference on "Recent Advances and Challenges in Engineering and Management", 2014-04) Ansari, Zakir
    Improvements in quality teaching-learning help in effective concept learning by the students. This has become a mandatory requirement for the institutes providing professional courses like Engineering, Architecture and Pharmacy. This is because in such courses the focus is on learning concept so as to apply it in professional career of the students. In most of the cases different subjects of the professional courses are taught by different faculties. Their way of lecture delivery differs from person to person. The performance of the students is affected by some external factors as well as by the performance of their teachers. A survey of the factors affecting the students’ performance was done through the teaching faculties and two of the most significant factors were considered for improvement. The current paper aims at getting the responses of teachers having highest students’ feedback score through a questionnaire. The responses are for the factors affecting the performance of faculty. Based on the outcome of the survey the strategy to improve the teaching-learning process was decided. Keywords – Quality, Faculty performance;Engineering Education, Professional Courses;

    (AIKTC, 2022-05) Ansari, Zakir; Yadav, Ashish Shivkumar (18ME117); Siddiqui, Naushad Shamshad (18ME110); Shah, Kaide Azam Izharul Haque (18ME86); Shahriyar, Hussain Mohd Israil (18ME88)
    With the daily use of the traditional zip cutting machine we got an idea to make it automated. Earlier using the machine required a great humaneffort,manpower, time and there was also a high risk of accidents while using the machine so we decided to make it automated which will not only reduce all this thing but also it will increase the productivity. To make it automated we made auto feeding and cutting system with the help of arduino which reduced the human effort to a great extent. This helped to increase the productivity,accuracy,and reduce labour cost. Due to this the cost of the final product also got reduced and increased the profit margin. In this way we tried to make a effective solution for the problem by making it automatic.

    Practicing Problem Based Learning (PBL) for teaching quality control tools:Case study of metrology and quality engineering course
    (K.K.Wagh Institute of engineering education & research, 2019-06-08) Ansari, Zakir; Shaikh, Saad
    Teaching is becoming a challenge in the current era. The student's interest decreasing day by day due to a lot of other reasons such as use of social media, and other distractions. The conventional style of teaching is no more effective and lot of research has been made in the use of different teaching methods such as project based learning, peer to peer learning, problem based learning etc. All these tools happens to be effective for the current students. This is more often in subjects which are theory based. The current work aims at using the real life problems for teaching Quality Control Tools to students of Third Year Mechanical Engineering. There are some Quality Control tools which are used for imparting quality in the product or the process. These tools are useful for finding out the causes for a nonconforming process or a non conforming product such as Pareto Chart, Cause and effect diagram etc. The students were taught these tools with the help of some real life problems directly faced by the students. This helped in grabbing the attention of the students as they feel that whatever is taught is part of their daily routine. The students were also given assignments on the said topic related to their own problems. The effectiveness of the said work was determined by conducting a test on the said topic for the students who were taught using this tool and the other set of students who were taught the topic in the conventional way. It was found that there is a marginal difference between the learning levels of the students of both the groups. It can be concluded that the use of modern teaching methods proves effective for the learning of the students.

    Quality management system (QMS), an assistance for NBA accreditation at UG engineering programmes
    (The Indian Journal of Technical Education, 2015-03) Ansari, Zakir
    There is always felt a requirement of employable engineers by the corporate sector. There has to be some indicator for quality of a student passing from an Institute. Quality Management Systems (QMS) is a tool for implementing quality standards at an institute. The assessment of the quality for an educational institute is done by different certifying boards like National Board for Accreditation (NBA), Accreditation Board for Engineering and Technology (ABET) etc. In order to assure about the employability of a student passing out of the institute,accreditation is a vital tool. Because of this reason many institutes are opting for the accreditation for their different undergraduate programmes. It is a well known fact that institutions 4 going for NBA accreditation need a lot of documents to be prepared and maintained as per the NBA accreditation requirements. OMS is a system for executing activities in an organisation as per the defined procedures. There are a lot of similarities between QMS and NBA. However NBA requirements are very specific in nature and are restricted to an educational institute while QMS requirements are generic in nature which can be implemented in an educational institute, Manufacturing unit even at a hospital as it is the process certification and not the product certification. Hence for meeting the specific requirements of NBA, the generic requirements of QMS can be fulfilled which will help and assisst during NBA accreditation. The current paper discusses the the similarities between the two and the assistance that can be taken by implementing the OMS before applying for the NBA accreditation.

    (AIKTC, 2017-04) Ansari, Zakir; Khan, Naimuddin (13ME87); Khan, Abdul Rab (14DME130); Khan, Sahroz (13ME88)
    It started with review the historical data of energy consumption which can be compiled from the electricity bills. These data are important in order to understand the patterns of energy used and their trend. After obtaining the information on energy consumption, the next step is to set up an energy audit survey. this survey gives an information on present energy used. The energy utilization such as running hours of air-conditioning, lighting levels, locations of unnecessary air-conditioning and lighting due to unoccupied areas, temperature and humidity, chillers scheduling and setting, efficiencies of equipment’s and machine and the areas of high energy consumption and the possibility to reduce consumption and renewable energy resources should be record for further analysis. In renewable energy resources we are moving toward the solar energy, wind energy and hybrid resources which can be easily installed in all the four building of whole AIKTC campus. We are going to select this resources based on their initial cost, area requirement, power generation, annual profit, maintenance cost, payback period. For selecting renewable energy resources based on those factors we are going to work with Analytical Hierarchy Process (AHP). It provides a comprehensive and rational framework for structuring a decision problem. The base of AHP is comparing variables by pair wise by Matrix relationship. In this way, pair wise of the effective variables give an alternative solution.

    It is observed through research that Natural Fibre Reinforced Polymer Composite have high water absorption capacity. In order to make the commercial use of natural fibres, which are abundantly available at a very less cost, their water absorption is to be reduced. It was found that the chemical and physical treatment of natural fibre improves their water absorption ability. The current paper explores the different methods and treatments of natural fibre from the perspective of improving its water absorption properties. Keeping this in view the present work has been under taken to develop a polymer matrix composite (epoxy resin) using Coir fibre and to study its moisture absorption behavior. The composite are prepared with different volume of Coir fibre. This work aims to prepare and test samples for their water absorption capability. Four different samples are required to be prepared in the ratio of 30:70 for fibres to matrix respectively. The samples have the natural fibres treated under different situations such as untreated, chicken fat under cold treatment,chicken fat under hot condition and NaOH treated. The experiment are to be conducted as per ASTM D570-98. The prepared samples are to be kept in the water and are to be taken out after an interval of 12 hours to check the water absorbed. This has to be continued till the saturation level. It has to be estimated if the samples follow Fick’s law. Keywords:
