Abstract
A boiler is one of the most significant components in a steam power plant system, as steam from the boiler is used to crank a steam turbine, which drives an electric generator. A sootblower is a piece of boiler equipment that cleans the ash and scale that has built up on the pipes. The heat-transfer pipes have been reduced. When soot builds up on the pipes or the riser on the boiler’s walls, heat transfer is impeded, resulting in less heat transfer. The amount of steam produced by the boiler will decrease if the heat transfer is lowered. Heat transfer is small in superheaters, reheaters, economizers, and air heaters, as well as in heat recovery regions like superheaters, reheaters, economizers, and air heaters. as well as the pipes for the superheater, reheater, economizer, and air heater As a result, the main objective of the sootblower is to analyze it so that lost energy in the boiler can be reduced. It also enhances the boiler’s efficiency once the sootblower has been employed.

Published: December 2022

Abstract
ross flow turbines are widely used as turbines for driving micro-scale hydropower plants in rural areas, but their efficiency is still low because cross flow turbines only use one nozzle. The utilization of the potential energy of water is not optimal yet to be converted into pressure and kinetic energy of water in the nozzles with high water velocity hitting the turbine blades. The problem of cross flow turbines with one nozzle has an uneven flow of water to the turbine blades, and it is not effective in converting potential energy into power in the turbine. The purpose of this research is to develop a four-nozzle Cross Flow turbine and test its performance. The method used is to conduct experimental testing in a laboratory that tests the performance of a cross flow turbine using four nozzles. A cross flow turbine with four nozzles has better performance than a cross flow turbine using only one nozzle. The results obtained that the cross flow turbine with four nozzles where the water jets out of the nozzle is more evenly distributed and the flow of water enters the turbine blade runner, resulting in a good impulse reaction in the blades. The conclusion is that the performance of the four nozzle cross flow turbine is able to produce higher turbine rotation, power and efficiency.

Abstract
This study aims to design and build an android-based trouble tictket application in order to support the implementation of the SLA (Serive Level Agreement). This idea originated from the increasing number of internet users in Indonesia, so that the level of competition among internet service provider companies is also increasing. This condition makes consumers more selective in choosing internet service providers. Companies must improve their services by ensuring the availability of network connections can be served optimally. Service Level Agreement (SLA) is a document agreement between service provider companies and customers as a guarantee that the company will provide excellent service. A trouble ticket system is a mechanism used in an organization to track, report, and resolve several types of problems experienced. The ticket in question is the numbering of trouble reports that customers send to service providers so that trouble is handled quickly. Through this system, customers can directly communicate with technicians so that service becomes easier, more effective and efficient. This trouble ticket application uses Firebase as the database and Android Studio software.

Abstract
In the field of transportation, one of the technological developments can be found in the parking service system. However, in the current parking service system, there are still several shortcomings, one of which is the absence of a parking system that can provide information to motorists regarding vacant parking locations. If the condition of the parking lot is congested, it will be difficult for customers to find an empty parking location and cause queues at the parking location. The purpose of this study is to design a system for calculating the availability of parking spaces that can make it easier for motorists to find an empty parking area so that the mobility of vehicles in the parking lot can be organized, efficient, and well organized. This smart parking system is designed using an Arduino microcontroller and uses an infrared sensor to detect the condition of the car in the parking lot. The information provided in the form of parking conditions will be displayed through the LCD and the LabView application so that the information can be known by the driver before entering the parking area. In addition, drivers can also find out the number of parking fees for their vehicles. Results of the simulation show that the prototype can work normally according to the design made.

Published: December 2022

Abstract
University campuses have a long history of enriching the social, cultural, and economic value of societies. Worldwide, there is a rising demand for the integration of new approaches into the planning and design of university buildings to further improve their quality. According to the literature, many approaches needed to be considered while designing university buildings that can enhance students’ performance. Biophilic design is known to have enhancing levels of interaction, and interaction patterns, enhancing health and wellbeing in terms of physiological, psychological, cognitive, and social/ spiritual benefits, while rigorous scientific evidence that supports such claims is rare. Many researchers have previously investigated the application of biophilic elements in working environments, however limited research is related to university building designs, specifically in Egypt. There is limited research on methods for quantifying the effect of biophilic design patterns on the physiological, and cognitive benefit. Thus, in light of the concept of Biophilia, this research aims to identify the correlations between the biophilic patterns and enhancing student performance. Survey questionnaires were administrated to a sample of students who regularly use the selected drawing studio. The extracted data will be analyzed through the use of SPSS software. This paper will benefit researchers who are interested in this field and may serve as a suitable beginning point for them and designers as well as a guideline while designing a university using biophilic patterns.

Published: December 2022

Abstract
Recent economic and population growth patterns in Egypt almost guarantee that energy consumption and emissions will continue to rise rapidly if nothing changes. According to the United Nations Development Program, Egypt’s energy demand will have been triple by 2030. Additionally, Egypt’s total emissions from energy use have been increased eightfold since 1971. The construction industry has been pushed to adopt sustainable building strategies, and the consensus among researchers and practitioners is that the most important phase to make decisions about is during the early stages of design. Arguably, high-performance buildings require a different design mechanism than traditional methods to achieve a holistic, sustainable outcome. Indeed, Building Information Modelling (BIM) can greatly facilitate the informed sustainability in buildings. Although BIM and sustainable design emerge from different underlying factors, they share an important common thread: the success of both depends on large part of building design philosophy loaded from the start. In fact, BIM can greatly facilitate the informed sustainability in buildings. Within the framework of reviewing the literature, researchers concluded the importance of BIM in the early stages of building design. The authors conducted an applied case study to evaluate a residential building in the new Administrative Capital in Cairo, Egypt, and concluded a set of design upgrades to raise the energy efficiency of the building and reduce carbon emissions from operating energy.
