Abstract

This community service program aims to increase the production capacity of the creative rencong souvenir industry through mentoring in mastering mass printing technology. The rencong, as a traditional Acehnese weapon, has been transformed into a souvenir product with significant economic potential, yet it remains constrained by the limitations of conventional production techniques. Through this program, craftsmen and small and medium enterprises (SMEs) in the rencong souvenir sector receive intensive training and mentoring on efficient and high-quality mass printing techniques. The methods employed include technology transfer, hands-on training, and continuous monitoring to ensure program sustainability. The expected outcomes are improved productivity, production efficiency, and product quality standardization, ultimately enhancing the competitiveness of the creative rencong souvenir industry in both local and national markets. This program is also designed to positively impact local economic empowerment while preserving Aceh's cultural heritage through innovative creative industry products.

Abstract

Pyrolysis is a thermo-chemical which decomposition of organic material through heating process with absent or little oxygen (anaerobic). The purposes of study are design pyrolyzer of coconut shell being to alternative fuels, knowing much of oil from pyrolysis process with method of counter flow and parallel flow, and knowing heat energy or caloric energy which was produced from pyrolysis process with method of counter flow and parallel flow in condenser. The research with through experiments the pyrolyzer which includes reactor, distribution pipe, and condenser. Research methods are the experiment of pyrolysis process at temperature 35oC during 60 minutes with condensation method, counter flow and parallel flow. Results of experiments are data of gas fuels mass obtained 42 grams which used pyrolysis process of coconut shell in the amount of 1000 gr, until produces pyrolysis oil as 198 grams (counter flow) and 196 grams (parallel flow). Counter flow method can absorb a heat as 1304,762 kJ and heat loss through gasses as 462,842 kJ, even though parallel flow no more than absorb as 1200,83 kJ and heat loss through gasses as 545,271 kJ.

Abstract

The use of plastic and goods made of plastic have been rising in day to day. Increasing use of plastics is a consequence of the development of technology, industry and population. On one hand, the invention of plastic has a remarkable positive impact, because it has many advantages compared to other materials. But on the other hand, the plastic waste has negative impact that too worried, so its solutions need to be looked for. One of the alternative handling of plastic waste that currently extensively researched and developed is converting plastic waste into fuel. Converting plastic waste into fuel oil can be done with cracking process. There are three kinds of process that is hydro cracking, thermal cracking and catalytic cracking. Fuel oil produced from the cracking of plastic waste depending on the plastic type, cracking process used, catalyst type, pyrolisis temperature and condenser temperature.

Abstract

This experimental study examines the impact of speed variations on the 2.5 mm nozzle diameter in low-carbon steel laser cutting. The primary objective is to optimize the roundness of the cut by considering cutting speed factors. Through a series of experiments conducted on low-carbon steel plates measuring 200 mm x 200 mm, utilizing a 2.5 mm nozzle diameter with speed variations of 2, 3, and 4 m/minute, the research measures roundness quality using a digital caliper. Results indicate that cutting speed influences roundness quality, with the lowest deviation observed at a speed of 2 m/minute and the highest at 3 m/minute. The study also highlights that increased cutting speed and the use of a larger nozzle require higher gas pressure.
