Abstract

The small size of the quadcopter and the low inertia of the drone allows the use of a simple flight control system, with the practicality of the Quadcopter it is hoped that it can be used for disaster management so as to increase regional resilience. Quadcopters issued by the company cannot be changed. This research is done by assembling the quadcopter itself and making changes to the propeller pitch to determine the effect of thrust and thrust motor on a quadcopter type x. From the results of research and calculations carried out, the thrust produced with a 50o pitch angle is greater than the 43o pitch angle for each movement, so the greater the pitch angle, the greater the thrust generated by the propeller. . The voltage that enters each motor will be different depending on its movement. So, the greater the voltage that enters the brushless motor, the higher the rotation of the motor so that the thrust generated is also greater.

Abstract

Processing of waste biochar into briquettes as a substitute for biogas to support the roasting process of Arabica coffee processing is an alternative energy innovation as a substitute for conventional charcoal derived from wood and biogas from LPG as well as to support energy security. Briquette is a material that is strongly influenced by the nature and type of the materials that make it up. This study aims to determine the effect of the composition of briquettes with a mixture of coffee husk waste and sawdust on the calorific value, moisture content, ash content, and density test. The method used is experimental. In composition III the density value is the highest because the amount of sawdust is the most. because with the treatment of the compressive force manually, the charcoal particles will experience compression in accordance with the given compressive force. The results of the research on composition I yielded a calorific value of 6052 cal/gr, composition II yielded a calorific value of 6122 cal/gr and composition III yielded a calorific value of 6333 cal/gr. The results of the ash content test of SNI 01-6235-2000 regarding charcoal briquettes, the permissible ash content does not exceed the value of 8%. The ash content produced in composition III is according to the specified standard

Abstract

Community service activities were attended by 29 participants from 33 registrants via Google form, this activity was carried out online using Google Meet. The purpose of this activity is to increase participants' knowledge about the importance and benefits of the stages in preparing standard operating procedures for their business. Another objective is to increase knowledge about the implementation of good standard operating procedures. Community Service activities are carried out through 3 stages consisting of: the preparation stage, the implementation stage, which consists of several phases, namely: the initial phase, the working phase (the servant introduces the activity participants, the servant conducts material presentation). The next stage is the activity evaluation stage which consists of evaluating the activity process and evaluating the results of the activity. The objective of community service activities has increased with an average increase of 47.84%. This shows that the knowledge of participants in community service activities regarding standard operating procedures has increased and is in accordance with the objectives of the activity.

Abstract

The original concept for the Easy-Fly project was to create an ultra-light STOL (Short Takeoff and Landing) plane featuring minimal drag and speed attributes. To support this goal, CFD (Computational Fluid Dynamics) was applied by varying the configuration of single-grooved flaps and slats and the angle of attack on the NACA 2412 airfoil. The viscous model used in this case is Spalart-Allmaras. The variation of the angle of attack (α) was modified in the range of 0°-20°. For the flap model, the deflection angle was adjusted to 30° and 40°, and slats were added to the configuration. Based on the results of the study, it was found that flap deflections of 30° and 40° resulted in higher CL values ​​at an angle of attack of 0°. The use of flap and slat designs on the NACA 2412 airfoil effectively delayed airflow separation until it reached a maximum angle of attack of 24°. In addition to the high-lift system design on the NACA 2412 airfoil, changes in camber and effective chord line adjustments resulted in significant improvements in the lift coefficient (CL), drag coefficient (CD), and stall angle. Finally, a 30° flap deflection was more efficient than a 40° deflection in takeoff conditions. The average percentage increase in CL/CD from a 30° to a 40° flap was 17.61%.

Abstract

Mahasiswa sering mengalami kesulitan dalam memahami konsep Gerak Lurus Berubah Beraturan (GLBB), khususnya pada aspek matematis dan visualisasi gerak dalam pembelajaran Fisika. Penelitian ini bertujuan untuk mengembangkan media pembelajaran berupa simulasi dua dimensi pada materi GLBB dengan konteks gerak pesawat terbang serta menguji kelayakannya sebagai media pembelajaran. Metode yang digunakan adalah Multimedia Development Life Cycle (MDLC) yang meliputi tahap perancangan, pembuatan, dan pengujian media. Pengujian dilakukan melalui blackbox testing untuk memastikan fungsionalitas sistem dan uji pengguna menggunakan kuesioner terhadap 30 responden. Hasil penelitian menunjukkan bahwa simulasi dapat berjalan dengan baik dan mudah digunakan, dengan tingkat kelayakan sebesar 89,33% yang termasuk dalam kategori sangat layak. Dengan demikian, simulasi dua dimensi yang dikembangkan efektif sebagai media pendukung pembelajaran Fisika untuk membantu mahasiswa memahami konsep GLBB secara lebih visual, interaktif, dan kontekstual.
