Abstract

Microbial fuel cell (MFC) is a technology that utilizes the biological activity of microorganisms to produce electricity from organic energy in the form of waste. Waste that is often encountered in everyday life, some of which are rice washing water and banana peel waste, which are easy to find and are often thrown away without being used, even though they contain organic content, which is a food source for microbes, which can later be converted into metabolic products from these microbes to produce electricity. Electricity within the microbial fuel cell (MFC) system. The microbial fuel cell in this research used a variety of substrates of rice washing water, banana peels and a mixed substrate of rice washing water and banana peels, as well as variations in incubation times of 3, 5 and 7 days. From the research that has been carried out, it is known that variations in the substrate mixture of rice washing water and banana peels (50%; 50%) have the greatest electric current, namely 0.262 mA at an incubation time of 5 days. In all substrate variations, there was an increase in electric current on the 3rd and 5th days of incubation and a decrease on the 7th

Abstract

Robot technology has penetrated various sectors, including households. One example of robotic innovation for household needs is the vacuum cleaner robot. This research aims to optimize sensor usage while implementing a differential drive system using a tricycle platform consisting of one caster wheel and two differential wheels. Testing was conducted in a space measuring 150 cm × 130 cm with obstacles such as a four-legged chair, cracker crumbs, sunflower seed husks, small pieces of paper, and a handful of dust (flour). The results showed that the robot could navigate quite smoothly and optimally even only using an HC-SR04 ultrasonic sensor. However, more complex challenges within households, such as getting stuck in carpet rolls, handling various types of trash or debris, or moving in narrow spaces, are still aspects that this robot has not fully addressed

Abstract

An ornithopter or flapping-wing is a robot that resembles the wings’ mechanics of birds, insects or bats. The application of this type of UAV ranges from photography to the military. This study's main discussion is designing and constructing the ornithopter wing mechanical system with a double-joint wing flapping system. The novelty submitted in this study was the material used to construct the ornithopter wing, namely rod carbon for the skeleton and plastic for the wing. The aim was to discover the aerodynamic performance of the wing and the whole ornithopter. The study results showed that for single wing, the value of CL/CD was high. However, the ornithopter design should be improved to get the thrust force higher than drag force. In addition, the velocity starts to increase stably at throttle 33.3%. Furthermore, for the ornithopter, it was found that the lift force was greater than the down force, so that, theoretically, the robot could fly. The largest lift occurred when the frequency values were 0.88 and 0.97

Abstract

This study aims to analyze the effect of variations in fuel brands, spark plug types, and tire pressure on four-stroke motorcycle engine performance. The independent variables tested include three variations of fuel brands (Pertamax, Shell Power, and AKR 92), spark plug types (standard, iridium, and platinum), and tire pressure (28 psi, 33 psi, and 38 psi). The experimental method was conducted on a Honda MegaPro PGM-FI motorcycle by measuring torque and power at various RPM using a chassis dynamometer test equipment. The results show that the sample 2 with combination of Shell-Super fuel brand, platinum spark plugs, and 33 psi tire pressure has a significant positive impact on engine performance, with higher torque and power as well as more consistent variations than other combinations. This research has important implications for motorcycle users, enabling them to optimize vehicle performance by choosing the right fuel, keeping spark plugs in good condition, and maintaining optimal tire pressure.

Abstract

One-third of Indonesia's territory is ocean, but Indonesia still experiences difficulties in clean water, especially in coastal areas. Solar still technology can be used to overcome these problems. There have been many studies conducted to improve the performance of solar stills, one of which is to change the shape of the cover or cover. The purpose of this study was to compare the effect of pyramid cover with the addition of condensation chamber (WES). This research uses experimental and theoretical methods. This study used fin absorbent plates using mortar material. The result of this study is the highest solar still performance using the WES cover compared to using the pyramid cover experimentally and theoretically. The highest productivity using WES cover is 2,087 kg / day for experiments and for theoretical values of 2,287 kg / day, while the efficiency obtained is 31.66% for experiments and 32,19% for theoretical. The difference in freshwater productivity and solar still efficiency between experimental and theoretical was not significant.

Abstract

Plastic injection (injection molding) is a method of forming products from plastic pellets into various daily necessities products. In terms of supporting daily needs, plastic injection molded products must meet criteria, such as strength, ductility, flexibility, hardness, etc. One of the easiest ways is to do a tensile test. In this research, mold with the shape of tensile test specimen products was carried out through several process stages, namely design and simulation, fabrication, and product testing. Autodesk Fusion 360 software is used in the design process to simulate and predict material flow during the injection process into the mold with several parameter variations in the form of time, material temperature and mold temperature. The results obtained were by using polypropylene (PP) plastic material, the maximum injection conditions were by suing a melting temperature of 230°C and a mold temperature of 50°C with an injection time of 14.5 seconds, where it was predicted that the product would be easy to fill and the resulting quality would reach 100% good. This research has succeeded in designing and predicting a plastic injection process that can be utilized in the plastic molding process through the actual injection process in industries that use polypropylene material.

Abstract

Rehabilitation methods for the physically disabled can be done by utilizing movement aids or prosthetics. However, most prosthetic fingers on the market only focus on aesthetic functions without paying attention to the function of finger mechanics so that not all people with disabilities who lose fingers can utilize various types of prosthetic fingers. The purpose of this research is to develop a prosthetic finger design to be more affordable for people with disabilities with a high level of accuracy and organization and produce prosthetic finger products that have good performance and strength, and in accordance with the needs and desires of users. This research involves experimental methods and iterative testing. The use of this prosthetic finger is limited to people with disabilities who have lost their fingers. The success in this research shows that the components used in the prosthetic finger function properly until the prosthetic finger can move effectively with a delay between the TTP223 touch sensor module and the finger moving 132 milliseconds to 148 milliseconds from 0 degrees to 180 degrees.
