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

This community service activity is a collaboration between academics and MSME entrepreneurs. The purpose of the activity is for MSME entrepreneurs, alumni of the Adisutjipto Aerospace Technology Institute to gain knowledge about ethics and codes of conduct, especially in terms of doing business. Besides discussing ethics and code of ethics, it also discusses standard operating procedures in managing business. It is hoped that the discussion of standard operating procedures can improve the quality of MSME products produced and can increase sales. The next discussion is about marketing strategies either through opening outlets/stores or by using social media and the internet. This community service activity uses a webinar because of the world situation due to the covid 19 health disaster. To find out the response of the webinar participants at the end of the activity, questions are asked with a questionnaire, from the results of the questionnaire with the question whether the activity is interesting there are 92% of participants answering interesting activities, 4% not interesting, 2% answered normal and 2% did not answer. participants in community service activities were also given questions about the answers of the speakers to questions from 94% of participants answered that the speakers gave good answers and 6% of participants answered that the speakers did not give good answers. In addition, a SWOT analysis was also carried out on partners in community service activities to obtain an overview of partners' strengths, weaknesses, opportunities and challenges.

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

Population growth and technology development are increasing rapidly. These cause the use of energy on the earth is increasing. One effort to obtain energy sources is to utilize solar energy using solar water heater. This research was expected to help the society to save energy derived from fossils. A testing was conducted by designing solar water heater with collector size of 60 cm x 50 cm using black painted aluminum-coated styrofoam insulator and the storage tank made of stainless steel with volume of 40 liter using black painted aluminum-coated styrofoam. In conducting the testing, the data were taken at 09.00 a.m until 04.00 p.m for 5 days. The research was conducted at ITD Adisutjipto. The analysis and discussion showed the solar water heater design and the storage tank used to perform performance the test (efficiency). Within 5 days testing the average of water temperature out (Tout) was 59.75 oC to 76.59 oC with the average rate efficiency of 54.07 % to 54.9 % and the average storage drop rate of 2.97 K / Hr or 17.84 K for 6 hours
