Journal of Engineering Researcher and Lecturer
ISSN : -     EISSN : 29637511     DOI : 10.58712/jerel
The Journal of Engineering Researcher and Lecturer is dedicated as a forum for researchers and lecturers around the world to report the research results. All papers are peer-reviewed by at least two referees. The scope includes technological and learning innovation in engineering (miscellaneous). Technological innovation must be carried out continuously for a better life. However, its sustainability is inseparable from human resources. Thus, manuscripts on learning innovation are expected to be a reference in decision-making for a policy on engineering education, resulting in superior students in a sustainable manner. Technological innovations are expected to be a learning reference and can be mastered by students for sustainable human resource development.

Abstract

Wind is an abundant energy source available in nature, which is renewable and environmentally friendly with high work efficiency. Indonesia has a wind potential of 978 MW, with wind speeds ranging from 6-8 m/s in onshore areas to above 8 m/s in offshore areas. Therefore, we should be able to capitalize on this energy resource. This paper will analyze the performance of NREL's 822 taperless type using the Q-Blade application. The research method used begins with a literature study to find natural parameters that will be later calculated using Excel to obtain the geometry parameters of the blades. Then, the data is entered into the Q-blade software by dividing the blades into ten elements and optimizing them. The blade material used in the manufacture is mahogany wood. This paper will discuss the manufacture of taperless blades with NREL's 822 airfoil. The blades were previously designed using MS Excel and Q-Blade applications and then further designed using the Solid Work application.

Abstract

The 21st century is characterized by rapid developments in information technology and automation, with many routine and repetitive jobs being replaced by machines, both production and computers. The world of his technical and vocational education curriculum in the 21st century is full of challenges to face. Technical education and vocational education must be able to create learning that is able to make students have the competencies needed by the world of work in the 21st century. Technological developments make changes in economic, social culture and including education. This article aims to examine the competencies needed in the 21st century and how effective learning is for this century. The research was conducted using the literature review method. In the 21st century, the world of work is increasingly complex, graduate students from technical education and vocational education must have learning skills, literacy skills and life skills. Skill competencies taught to students must focus on one particular area, because in the world of work each worker will only do one type of work. Learning in technical and vocational education is recommended to use the application of the project-based learning model. Various research results have found that this model is able to make students have the skills needed in this 21st century.

Abstract

The increasing demand for energy, driven by population growth and reduced sources of oil reserves, puts pressure on every country to produce and use renewable energy as a substitute. One of the alternative energy sources is biogas, which is produced using EM4 bacteria that balance microorganisms. In this study, microorganism inoculants consisting of 90% Lactobacillus, produced from cow dung, were accommodated in an HDPE plastic container with a volume of 1 m3. Data collection was carried out from the first to the fourteenth day, with pressure data retrieved using a pressure gauge, temperature data retrieved using a thermometer gun, and the volume of biogas measured using an Arduino-based flow meter. The study found that a 1x1 meter HDPE polymer container can accommodate a maximum biogas volume of 208.12 liters. In the non-continuous system, the volume of biogas produced is not stable. The total volume of biogas produced before going through the filter for 14 days was 1075.12 liters with an average volume of 76.79 liters/day, while the total volume of biogas that had been through the filter for 14 days was 995.71 liters with an average volume of 71.12 liters/day.

Abstract

An expert system is one of artificial intelligence that uses a computer to work like and as well as humans do. An expert system is a computer system that is designed so that it has the ability and reasoning like an expert. But, the expert system is not used for replacing an expert who in this problem im a psychologist as a consultant for students want to recognize the potential and their abilities. The expert system is only used as equipment and limited tools. There is a problem is how to design tools to help students recognize their potential and abilities, so that they can choose the right department in the University based on their potential and abilities. Expert system design for assign department in the University based Multiple Intelligence use visual basic programming language and Microsoft Office Access as database.

Abstract

Chassis is the most important part of a truck, because it is closely related to the safety and weight of the truck. The profiles used for truck chassis differ as follows: C-channel, U-channel and rectangular tube. This study aims to reveal the most ideal profile for use as a truck chassis. The study was conducted using finite element analysis. The study conducted was buckling analysis. The variables observed for each test profile are free vibration, buckling safety factor, and deformation scale. the C channel profile is most ideal for use as a truck chassis. The simulation results show that the C channel profile has a buckling safety factor > 1 and the smallest average deformation occurs in each shape mode. The U channel profile has a light weight, but the deformation that occurs in each shape is greater than that of the C channel. The rectangular tube profile has the greatest safety factor in each shape mode, but has the largest deformation scale and weight.
