    (2022-05-25) Mohammad Shtewi; Lana Khirallah; Rawan Jarad; Shahd Qatanani; Duha Hara
    Given that our state, Palestine, is under Israeli occupation, it lacks the use of the latest smart technology in all sectors, which means cutting off from the smart world in the simplest developments that occur in the world. Here where many problems occur in all sectors, the most important of which is the educational sector, which is the basis of the industrial revolution in the world. Here, we start by talking about many problems that are facing the educational sector in Palestine, especially the recent pandemic (Covid-19) and it’s resultant damages, from a permanent interruption of education in universities, schools and all educational institutions, and heading to distance learning using the latest applications and websites, compared to other countries. On the other hand, universities lack the latest smart means used in education .So the smart campus can make the university life easy and could resolve some of the obstacles such as Unavailability of vacant parking spaces for faculty members and students , Unavailability of automatic umbrellas in the open yards in winter , The lack of a control system for refrigeration and air conditioning devices according to the weather condition , Facilitate the process of recording attendance and absence in lectures , Students crowds at the cafeteria , Lack of smartboards , Poor design and layout of classroom chairs , Conflicts in exam dates , Reservation of halls during examinations , Excessive spending on electricity (halls, laboratories, offices, corridors) , Unavailability of the map for the structure of the university . To provide all the necessary means to solve the problems facing all groups in the university (the board of directors, education staff, students, employees) in the best, most advanced, and intelligent way (IoT). With the great development that the world is witnessing in the light of information technology and the Internet of things, all mechanized operations in all aspects of operations are implemented in smart ways and with very wide and different techniques, for example, a house cannot be devoid of a mobile phone or laptop, and this represents the simplest things that depend on technology We realize here the importance of using modern technology in all aspects of life, whether in the medical, educational, economic, agricultural, and other fields. The importance of having smart technologies that support and enhance the educational process. During the research, we studied the operations within the departments of An-Najah National University and the existing challenges and obstacles faced by students, teachers, and administrative staff, as the problems and obstacles that somewhat affect the functioning of operations were sorted into academic problems and administrative problems. Regarding administrative problems, we mention the problems (activities that can Develop them) the following: first, time, crisis management, archiving, information preservation, logistical operations that take place inside the university, financial matters facing the financial department, the registration process for new students, warehouses and administrative buildings Concluding the academic aspect, we mention several problems related to the educational rooms, as they lack the presence of central heating and air conditioners, as well as the lack of a smartboard through which to save the information that is included for all the educational materials that are taught, and also during the examination period, there are several problems facing students such as the problem of the lack of a number There are enough chairs in the halls. Exam dates also conflict with each other. There is limited access to the educational resources in the library, as they are not available outside the library, and this makes it difficult for me to obtain the necessary information during the educational process. In particular, we mention the problems facing the teaching staff inside the halls, which are the problem of attendance and absence and the cumbersome and time-consuming paper processes inside the lecture. In particular, where more than 1000 lectures are given per week, and if we assume that the educational staff does not adhere to the process and its percentage is 50%, then we are talking about more than 500 lectures that are lost in the process of attendance and absence throughout the semester, and this is a great wasted time and can be improved and developed with modern and smart techniques

    Current Status of Stone-Cutting Waste Management in Palestine.
    (2022) Rahaf Ghozzi; Bara’a Abu Baker; Abdelraheem khateeb; Saad Jodallah
    Stone and marble sector is one of the most important industries worldwide. its annual sales reach about 10% of the global market. Palestinian stone takes 4% of global. Palestinian stone is exported to more than 80 countries, it represents about 4.5 percent of Palestinian GDP and employs 20,000 workers directly and 100,000 workers indirectly in about 1200 facilities. However, the stone and marble industry in Palestine suffers from a high present of stone waste produced, while adopting inadequate methods dealing with this waste. Moreover, there are clear negative impacts of this waste on both the environment and human health, hence this industry weakly complies with sustainability standards. Also, in this project the effect of waste management on the organization's performance was investigated from the point of view of factory owners. The goal of this project is to assess the current local stone-waste management practices. During the project a comprehensive literature review was conducted on previously published work about Palestinian stone, local stone waste management practice, global best practices in dealing with stone waste, and about standard waste management models. Furthermore, a questionnaire was developed to collect quantitative and qualitative data. Finally, based on data collected from 53 factories, it appears that the final product has 52.18 percent raw stone input and 47.82 percent waste of production. Furthermore, annual solid waste amounts to an average of 1901.38 tons, or 26.49 percent of raw stone. On the other side, annual liquid waste amounts to 1736.77m3, or 86.99 percent of total input water (of course liquid waste includes fine powder as well). In addition, the majority of factories dispose of solid waste in crushers and treat liquid waste in purification plants and silos, according to the data. While factories who don’t treat the liquid waste, most of them get rid of the liquid waste in random landfill. For sludge, most of factories don’t use it, and dispose it in dedicated landfill.

    Applying Lean Manufacturing Tools at Al -Karmel Islamic Company
    (2022-12) Baraa Yaseen; Lamees Zamel; Sarah Arman; Yazan Qadi
    In Palestine, meat processing is regarded as one of the most important sectors in the food industry. There are 17 factories in operation, employing more than 559 people, with a total investment volume of more than $25 million dollars. This industry ranks first in the food industry, with Palestinian meat products accounting for 90% of the market. This sector represents a significant investment in the local economy, requiring more than 100 tons of various varieties of meat per day. Al-Karmel Islamic Factory (KIF) is a Palestinian meat processing which is the case of this project. This project’s major goal is to reduce the various types of waste generated in KIF which will help boost efficiency and production, improve quality, and lower costs. To this end, Lean Six Sigma (LSS)-DMAIC (Define, Measure, Analyze, Improve, and Control) methodology will be employed to eliminate waste and improve performance and efficiency in KIF. More specifically, three production lines at KIF are considered for eliminating waste represented by over processing, reducing lead time, and increasing productivity, and increasing efficiency while maintaining customer satisfaction and quality assurance. In this project, we applied the five stages of DMAIC on 3 production lines for five products, which is the salami production line, including two salami products 1200g and salami 800g, the pastrami production line, from which samples were taken from the 200g pastrami product, and the hotdog production line, where the hotdog variety was taken 1000 g and hot dog 400 g. During these stages, we took random samples of sample size 4, and we reduced the waste in product weights and reduced the mean deviation from the target weight for each of these five products, in order to achieve significant cost savings and make some recommendations in order to preserve on this performance improvement.

    Feasibility study for Olive mill pomace piston
    (2021-05-16) Bara Melhem; Ali Abdullah; OBYDA ABBADI ; Razan Daher; Roaa Sawafta
    Peat is one of the remnants of the olive pressing process that can be exploited and converted into a flammable material to become one of the alternative sources of energy. It is obtained in the fall or early winter after the olive harvest and pressing season. Fortunately, modern mills sort olives from peat separately. What makes it easy to use. Our project studies the feasibility of establishing a factory for peat presses in Palestine. In this project, the importance of peat exploitation was highlighted. In this study, we focused on the production line operations for the production of peat presses in various briquettes. Since agriculture is one of the most important components of the Palestinian economy, and it can be said that olive cultivation specifically in Palestine represents the vital nerve of agriculture, Palestinian environmental studies in the field of olives have become some of the advanced olive products, whether at the level of using olive peat, or processing olives, or even extracting raw materials such as those in OLEUROPEIN). The production represents 57% of the cultivated lands in the occupied Palestinian territories, with the total area planted with olive trees amounting to 498 thousand dunums, while nearly 11 million trees are in the West Bank and the governorate. Oil, olive pomace, zebra and other substances that can turn into a disaster unless they are exploited. These factors lead to thinking about building the factory and increasing the demand for production. After describing the benefits of olive pomace (peat), the amount of mold consumed in some areas in Palestine was estimated. The concept of market share is described and calculated using four different scenarios.In addition, emphasis was placed on how to make peat briquettes from start (raw material) to end (final product), knowledge of production equipment and manufacturing machinery, their costs and characteristics. A layout of the plant is designed which includes warehouses, staff offices, arrangement of equipment and machinery, as well as calculating the area of each section of the plant based on the 30% market share scenario.

    (2022-12) Ro’a Omar Barham; Hala Nabil Demaidi; Rand Omar Ghannam; Isra Abdalsalam Haj Hamad
    Industries in general face problems in their production planning, maintenance systems, communication between departments and communication with customers. These problems increase the overall cost, decrease productivity and customer satisfaction. Arab Eastern Company (AECO) faces these kinds of problems too, such as poor production planning, non-documented maintenance system, poor communication between departments and in the order fulfillment process. This project is established to make improvements at AECO and it provides different options to solve these problems, starting with introducing different types of forecasting methods to apply systematic production and inventory planning, introducing a failure mode and effect analysis (FEMA) system to document the maintenance procedures, and also introducing tools and procedures to ensure the safety of the workers. Data was collected from AECO company and analyzed to define the main problems and start solving them.
