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.

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.

Publisher : Researcher and Lecturer Society

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.

The tail-shaft is one of the components of the apron feeder on the conveyor. Its role is quite significant, as it includes a take-up system to adjust the tension and slackness of the chain on the sprocket against the Lamella. Based on observations in a mining industry, it was found that tail-shaft damage frequently occurs, likely due to the excess load carried by the conveyor. Therefore, researchers were interested in investigating the maximum capacity of the tail-shaft. The research was conducted using the Finite Element Analysis method with Solidworks Research License. The material used for the tail-shaft is DIN 1.0038. Torque variations tested on the tail-shaft were from 42,000 N.m to 58,000 N.m. Based on the simulation results, the maximum torque that the tail-shaft can withstand is 54,000 N.m with a safety factor value greater than 1, whereas when given a torque of 58,000 N.m, the safety factor value is less than 1. The tail-shaft experiences a maximum stress that exceeds the yield strength of DIN 1.0038 material, which can cause damage to the material. The initial damage appears at the end of the shaft due to the use of chamfer. This is known based on the results of simulations that have been conducted.

The development of digital technology for education is continuously conducted to successfully integrate digital technology with people's lives. This study aimed to develop an Augmented Reality learning media application for the Engineering Mechanics course, which is considered challenging by some students. Engineering mechanics, a discipline that analyzes structural analysis in compensating for the loads that work on a particular machine in scalar quantities, motion forces, vectors, and moments that require physical structural forms to analyze them, is considered challenging by some students. The Augmented Reality application was created using the prototyping method, which consists of three steps: 1) listening to the customer, 2) building/ revising mock-up, and 3) customer test-drivers mock-up. The AR-based learning media application includes usage instructions, developer info, learning videos, 3D AR object animation simulations, and exercise and discussion menus, which were tested as expected. The results of the black box testing indicate that the Augmented Reality-based engineering mechanics learning media application ran successfully as expected. However, users suggested improving the navigation speed by streamlining page transitions. The application provides an accessible solution for students as an alternative to traditional distance education, offering anytime, anywhere access to learning materials with longer duration.

Various learning models have been developed and implemented in vocational education in the engineering field, but still have weaknesses, especially in basic matters such as one-sided learning and lack of direct industrial involvement. Moreover, learning in educational institutions is not supported by facilities that match those in the industry, but only simulation tools. Additionally, the media used in educational institutions is not as sophisticated as that used in the industry. This study is a literature review on Work-based Learning (WBL) and the formulation of WBL concepts suitable for vocational education in the engineering field. The results of the literature review showed that the implementation of WBL in various developing and advanced countries is very effective in developing students' competencies. Educational institutions and industries work together to improve the quality of learning to produce job-ready graduates. Industries benefit from the availability of competent and professional workforce who can develop their business for global competition. There are three WBL model concepts that can be applied to vocational education in the engineering field, including integrated student work, teaching factory, and industrial internship. The formation of student competencies can be carried out through a structured program, where students will gain experience and opportunities to gradually sharpen their competencies.

CO2 gas is a greenhouse gas that causes global warming. Greenhouse gases are gases in the atmosphere that can absorb and reflect infrared radiation from the Earth's surface. Currently, the energy demand still depends on fossil fuels. On the other hand, CO2 emissions from burning fossil fuels continue to increase and contribute as greenhouse gases to the atmosphere. CO2 capture is an effort to reduce the burden of CO2 emissions into the atmosphere and is part of the Carbon, Capture, and Storage (CCS) protocol. The CO2 absorption process applied in the chemical industry is one of the CO2 absorptions using NaOH and Na2CO3 solutions as absorbents. This research aims to determine the effect of absorbent flow rate on the percentage of absorbed CO2. The method used in this research is the SLR (Systematic Literature Review) method to identify all available research. The absorbent flow rate variations used are 1 liter/minute, 1.5 liters/minute, 2 liters/minute, 2.5 liters/minute, and 3 liters/minute. The absorption process using NaOH absorbent is capable of absorbing CO2 gas with a maximum absorption of 95.52% and a minimum of 79.14%. Meanwhile, in the Na2CO3 absorbent, it is capable of absorbing CO2 gas with a maximum amount absorbed of 72.45% and a minimum of 35.47%.
