Aluminum waste is a challenging material to manage due to its high production rate from households and industries. This study aims to repurpose aluminum waste into hydrogen gas, which can serve as an alternative fuel for gas stoves. Direct disposal of aluminum waste can lead to environmental damage; hence, this project focuses on developing a system that dissolves aluminum using sodium hydroxide (NaOH) to produce hydrogen gas in a tube reactor. This hydrogen is then used as stove fuel. The comparison between aluminum-fueled hydrogen and conventional fuels, such as Pertalite and LPG, suggests that aluminum waste has potential as a cost-effective fuel source. For instance, one liter of Pertalite at Rp. 10,000 powers a motorbike for approximately 30 km, translating to Rp. 1,428 for a similar distance with aluminum-derived fuel. A 3 kg LPG cylinder costs around Rp. 24,000 and provides 10 hours of fuel, whereas hydrogen produced from aluminum can be cheaper if sourced from waste. Additionally, this design incorporates a refillable reactor that sustains hydrogen supply during combustion, ensuring consistent stove operation. The system is portable, safe, and offers high mobility, making it practical for various applications. This approach not only reduces aluminum waste but also presents an affordable alternative fuel solution, enhancing environmental sustainability.

Ginger extract powder is a popular product in the beverage and health industry, requiring careful processing to produce high-quality results. This study aims to determine the efficiency of the stirring blade design on the ginger extract powder stirring machine. The intensive stirring process can lead to faster wear of the blades, making the selection of suitable materials crucial. The research was conducted through direct observation at UKM Bekti Pertiwi. The data collection process was structured to capture both quantitative data: 1) Energy consumption: energy used by the machine was measured in kilowatt-hours (kWh) using a standardized electricity meter, and 2) Cycle time: the time for a full cycle was recorded, from material input to the completion of the stirring process. A controlled sample of 2 kg of ginger essence was used in each test to standardize conditions and ensure consistent results. The sample size was chosen based on typical batch sizes processed by SMEs, aiming to represent common production volumes. The ginger essence sample was prepared with a standardized consistency and viscosity to reduce variability and ensure repeatability across tests. The stirring blade samples were manufactured from stainless steel with a Teflon coating, selected due to its corrosion resistance and durability in acidic environments. Blade dimensions were set to 504 mm in diameter and 3 mm in thickness, based on initial design research suggesting these dimensions as optimal for the desired mixing efficiency and wear resistance. Each test was conducted under the same operational settings, including motor speed and cycle duration, to maintain uniformity in testing conditions. Results indicate that a combination of stainless steel and Teflon in the stirring blades provides optimal performance, with energy consumption reaching 0.1072 kWh for 2 kg of ginger extract. The electricity cost for one production cycle is IDR 144.93. These findings can be used for future production planning, as well as to improve operational efficiency and the quality of ginger extract products.
