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.

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.

Wind is an energy source that is abundantly available in nature and is a renewable energy that is environmentally friendly and has good work efficiency. Indonesia has a wind potential of 978 MW with wind speeds generally 6-8 m/s in onshore areas and above 8 m/s in offshore areas. Therefore, with abundant wind potential, we should be able to take advantage of this energy. This paper will analyze the performance of NREL's 822 Taperless type using the QBlade application. The research method used begins with a literature study to find natural parameters which will later be calculated with the help of excel in order to get the geometry parameters of the blades, then enter the data into the QBlade software by dividing the blades by 10 elements on the blades and optimizing the blades in the Qblade software. Manufacture of blah with mahogany jens wood material. This paper will discuss the manufacture of taperless blades with NREL's 822 airfoil which was previously designed using the MS Excel and Q-Blade applications and then designed using the Solid Work application.

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.

The increasing demand for energy due to population growth and reduced sources of oil reserves puts pressure on every country to immediately produce and use renewable energy as a substitute, one of the alternative energy sources is biogas. The bacteria used in making this biogas is EM4, researchers used these bacteria because they can balance microorganisms. Microorganism inoculants consisting of 90% Lactobacillus produce cow dung are accommodated in a container made of HDPE plastic. The dimensions of the reservoir are 1 m3. Data collection was carried out starting from the first day to the fourteenth day. Retrieval of pressure data using a pressure gauge, temperature data retrieval using a thermometer gun and measuring the volume of biogas using an Arduino-based flow meter. From this study, it was found that biogas storage using HDPE polymer material with a size of 1x1 meters can accommodate a maximum biogas volume of 208.12 litres. In the non-continuous system, the volume of biogas produced is not stable with the total volume of biogas before going through the filter for 14 days is 1075.12 litres with an average volume of 76.79 litres/day while the total volume of biogas that has been through the filter for 14 days is 995.71 litres with an average volume of 71.12 litres/day.
