This study delves into the optimization of polypropylene cutting board production through injection molding. Polypropylene, derived from propylene monomers, serves as the primary material. The injection molding process often leads to flash defects due to inadequate temperature and pressure settings. The research aims to discern the individual and interactive effects of temperature and injection pressure on the weight and surface area of the cutting boards. Experimental variations encompass temperature levels of 165°C to 175°C and injection pressures ranging from 25 Psi to 35 Psi. Data collection employs experimental methods, and analysis utilizes factorial and RSM approaches. Findings reveal that the lightest cutting boards result from the lowest temperature (165°C) and injection pressure (25 Psi), with an average weight of 105.6009 grams and a surface area of 21,158.3333 mm². In conclusion, both temperature and injection pressure significantly influence the weight and surface area of polypropylene cutting boards, providing valuable insights for enhanced manufacturing processes.

Abstract

The increase in population means that the need for transportation is also increasing, causing more or less air pollution. Besides that, fuel oil is also a non-renewable natural resource. Oil fuel comes from plants and animals that have been dead for millions of years which have become fossils and which have been formed for a very long time  automatically become expensive. Therefore, people need vehicles that have many  advantages, including environmentally friendly, do not produce air pollution, do not produce noise, avoid traffic jams, and are easy to maintain. Flying electric vehicles are the right choice to overcome this problem. Electric car is a car driven by an electric motor that uses electric power stored in a battery. One of the advantages is that the engine construction is simpler compared to combustion engines which have so many components because there is combustion in the engine. Electric vehicles certainly need a chassis. The chassis that will be used is a tubular chassis type using fiberglass. The aim of this research focuses on planning electric flying vehicles, more precisely on static simulation of chassis design. The results of this research can be used as consideration for designing the chassis structure of flying electric vehicles. This research is expected to be the beginning of the development of an electric quadcopter flying vehicle chassis.

Abstract

This study examines the design and fabrication of innovative floating growing media based on 3D printing technology to support hydroponic systems in limited land and shallow waters. The design process was carried out using CAD software, then printed using a 3D printer with environmentally friendly PLA material. The four main components of the growing media produced were the Nutrition Tube, Nutrient Pipe, Buoy, and Water Grid, printed using constant parameters: a speed of 80 mm/min, a layer thickness of 0.2 mm, and a wall thickness of 0.8 mm. These parameters ensure precise dimensions and a sturdy structure. Tests showed that the growing media had stable buoyancy with a carrying capacity of up to 250 grams, buoyancy stability analysis used the CFD simulation method to determine the pressure distribution. The highest pressure was found in the Buoy area (12–15.89 Pa), while the bottom side of the float showed negative pressure (-4.9–0 Pa), indicating good hydrodynamic balance. These results indicate that 3D printing technology is effectively used in the development of lightweight, efficient, and customizable precision growing media, thus contributing to a sustainable floating farming system.

Abstract

properties and rapid combustion. However, optimizing the performance of dry cell HHO generators remains a significant challenge. This study investigates the effect of varying electrode materials (copper and stainless steel), electric current, and NaOH concentration on HHO gas production. The key performance indicator used is the flow rate of HHO gas produced. Results show that increasing electric current significantly enhances HHO production, though this relationship is non-linear due to the rise in electrolyte temperature and internal resistance. A higher NaOH concentration increases electrolyte conductivity, improving HHO production, but excessive concentrations can lead to higher temperatures and electrode degradation. Copper electrodes outperformed stainless steel in gas production due to better electrical conductivity, while stainless steel exhibited superior corrosion resistance over time. Optimizing the combination of electrode material, current, and NaOH concentration is crucial for enhancing the performance of dry cell HHO generators, offering valuable insights for hydrogen-based energy systems.

Abstract

This study aims to analyze the effect of the number of poles on the output power of the Permanent Power Generator (PPG). PPG is an innovative renewable energy system that utilizes permanent magnets to generate continuous electrical power without relying on external fuel sources. This study uses an experimental approach using 1 mm diameter wire and three pole configurations (3, 6, and 9 poles) to determine the optimal configuration to maximize power output. Voltage and current measurements were taken using a digital multimeter, and the power output was calculated using the formula P=V×I. The results showed that an increase in the number of poles significantly increased the generator's power output. The highest performance was achieved with a 9-pole configuration and a 1 mm wire diameter. These findings support the basic principles of electromagnetism, where a decrease in coil resistance and an increase in magnetic field frequency contribute to higher energy conversion efficiency. This study is expected to contribute to the development of environmentally friendly power generation systems and serve as a valuable reference in the design of high-power, high-efficiency generators for future renewable energy technologies.
