Abstract

The application of aquaponics in South Meruya has dual benefits, both in terms of improving the community's economy and food security, which ultimately improves the welfare and quality of life of urban communities. Aquaponics is an integrated system between fish farming and hydroponic farming that utilizes fish waste as nutrients for plants and filters the water that is reused for fish. The application of freshwater fish aquaponics in South Meruya is an innovative solution to address economic challenges and food security for urban communities. Aquaponics assists communities in generating fresh revenue by producing fish and vegetables for local markets. The relatively low operational costs and limited space make aquaponics ideal for implementation in urban areas with limited land, such as in South Meruya. Aquaponics allows communities to produce food independently and sustainably. Community food security increases due to easier access to sources of protein and fresh vegetables.

Abstract

The motivation for this research is the high vibration observed during the operation of the centrifugal cooling water pump. Our study aims to assess the pump's state and check the vibrations to ensure the factors underlying the fault of the centrifugal pump in the alkaline chlorine factory. While previous studies have primarily used spectral amplitude results from the Fast Fourier Transform to analyze engine vibrations, we propose a different approach in this study. We employ the Finite Impulse Response (FIR) Bandpass Filter and the Welch Method, a practical analytic approach. The ISO 10816-3 standard is a benchmark of the RMS value to determine the pump's condition. The FIR Bandpass Filter and Welch Method prove to be highly effective in describing and modifying the vibrational signals of the centrifugal pump. The approach is particularly beneficial as it is consistent across sample rate settings, reduces the vibration of amplitude low, produces a smoother spectrum with only the primary frequency component, and segments the vibration signal into the frequency band-aids to identify the primary vibration source. The diagnostic results reveal increased vibrations at 1x, 2x, and ball pass frequency (BPF), indicating impeller damage and disappearance. Post-repair, the vibration value experiences a significant drop, as per the fault analysis results, further confirming the high effectiveness of our approach. These findings have practical implications for the maintenance and fault diagnosis of centrifugal pumps, providing a reliable and effective method for identifying and addressing issues.

Abstract

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.

Abstract

Vibration is an inevitable physical phenomenon; excessive and uncontrolled amounts of vibration can result in damage and system failure. In accordance with various automotive product certification standards, vehicle batteries or rechargeable electrical energy stotrage system (REESS) must undergo a vibration test to assess their mechanical integrity. This study aims to broaden the perspective on vibration assessment by examining it during vehicle operation and assessing the protective capabilities of vehicle suspension against vibrations from damaged roads in two-wheeled electric motor vehicles. The proposed method involves installing an accelerometer on the battery pack body placed in the battery compartment. The experimental setup involved conducting tests on a 125-meter track, with the vehicle traversing roads characterized by concrete cracks, uneven surfaces, and potholes. Two distinct speed variations were selected for analysis: 10 and 15 kilometers per hour. The results obtained from the Rion VA 12 portable vibration analyzer are presented as a plot of the fast Fourier transform (FFT) graph. The maximum acceleration recorded was 2.35 and 1.98 G at the same frequency of 7 hertz (Hz). This research method and result aligns with others, including those focused on assessing road damage, passenger comfort, and vehicle component damage, such as shock absorbers. In the future, the development of a vehicle battery support structure is anticipated to further minimize vibration disturbance by reducing the peak acceleration values depicted in the FFT graph. The minimization of incoming vibrations is expected to enhance the safety and durability of the battery pack.

Abstract

Corrosion of carbon steel frames is a major concern in the automotive industry, especially for motorcycles that are often exposed to harsh environments. As an eco friendly alternative to synthetic chemical-based corrosion inhibitors, this study evaluates the effectiveness of corn husk extract as a natural, tannin-based inhibitor. Corn husks were selected due to their abundant availability as agricultural waste and their active compounds with potential anti-corrosion properties. The extract was obtained using maceration, reflux, and ultrasonic methods, and tested in corrosive solutions of NaCl, HCl, and H₂SO₄. The inhibitor’s effectiveness was assessed using weight loss measurements and surface morphology analysis. Results showed that corn husk extract reached up to 100% inhibition efficiency at a 600 ppm concentration, particularly in NaCl solution. The tannins and phenolic compounds in the extract played a crucial role in forming a protective layer on the carbon steel surface. These findings highlight the strong potential of corn husks as a green base material for corrosion inhibitors, while also promoting the use of biomass waste in developing sustainable corrosion protection technologies for the automotive industry.

Abstract

Bearing is a mechanical component that is used as a place where the shaft rests on its axis and rotates with the holder and the shaft. The use of these bearings is focused on reducing friction; therefore, the friction that occurs is getting bigger along with the load, pedestal, working temperature, and conditions of loading and rotation that occur on the shaft. Estimation of damage and bearing life will be carried out on several bearings from different brands, but with the same type and size. Bearings with type 6207 and bore diameter of 35 mm come from 7 brands, namely SKF-SS (the only type in this study that used stainless steel), SKF, NSK, NACHI, KOYO SEIKO, SKF, and NTN. This analysis is carried out using the Weibull method where bearing specification data is processed by entering data into existing equations and analyzing the results of the calculations performed. The dynamic load value affects the L10 value of 9.3217%, predicted R(t) 13.5349%, ηcat 9.2567%, and Actual Reliability 3.9158%, this is due to the relationship between each of the equations used. Based on the reliability value generated, it can be concluded that the type of bearing recommended is NTN.

Abstract

One of the most technologically advanced methods for developing and adhering catalysts to the FeCrAl substrate is electrophoretic deposition. However, it faces a problem: low thermal stability at high temperatures of 10000 °C, caused by a lack of a protective oxide layer. The goal of this study is to investigate the protective oxide layers formed by Al2O3 and NiO coatings on FeCrAl metallic material for catalytic converters (CATCO). The electrolyte was prepared with distilled water at a constant temperature of 40±50 °C. The pH was adjusted to 5 with HCl and NaOH reagents. The electrolyte was prepared at 40 ± 50 °C and stirred for 1 minute using a magnetic stirrer. A 50mm x 10mm Ni plate substrate served as the anode, while a 40mm x 20mm FeCrAl cathode was used. The spacing between the anode and cathode was set at 25mm. The electroplating was conducted for several variation times of 15, 30, 45, 60 and 75 minutes, current density of 8 A/dm2, 3g γ-Al2O3 was inserted into the beaker for each sample and the total surface area was 1600mm2 on both sides. Drying was performed after electroplating at 600 °C for 12 hours.  Raman spectroscopy revealed that several compounds observed during the experimental stages, such as FeCrAl, γ-Al2O3, NiO, NaO2, NiAl2O4, NiCr2O4, and FeCr2O3, were also present in the coated FeCrAl CATCO, with distinct peaks. Therefore, it can be concluded that the UB+EL 30 min successfully deposited the γ-Al2O3 and NiO on the FeCrAl substrate after CATCO fabrication.

Abstract

The increasing demand for sustainable and environmentally friendly corrosion inhibitors has driven research toward green alternatives to conventional toxic inhibitors. This study investigates the corrosion protection performance of garlic extract (Allium sativum) as an eco-friendly green inhibitor for stainless steel 316L in 3.5% NaCl marine environment. The inhibition efficiency was evaluated using electrochemical potentiodynamic polarization techniques, complemented by comprehensive surface characterization through scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, electrochemical impedance spectroscopy (EIS), and cyclic voltammetry analysis. Electrophoretic deposition (EPD) was employed to apply garlic extract concentrations of 8, 10, and 12 mL onto SS316L specimens. Results demonstrated significant corrosion rate reduction from 0.0082732 mmpy (unprotected specimen) to 0.0014547 mmpy with 12 mL garlic extract treatment, achieving maximum inhibition efficiency of 82%. EIS revealed substantial increase in charge transfer resistance (>170 kΩ), while electrochemical analysis demonstrated mixed-type inhibition behavior with reduced corrosion current densities. SEM-EDX confirmed the formation of protective Fe2+-allicin complex layers on the metal surface, while Raman spectroscopy showed substantial reduction in corrosion products (a-Fe2O3 and y-FeOOH) formation. Cyclic voltammetry demonstrated a five-order-of-magnitude reduction in diffusion rate, confirming exceptional barrier properties. The superior performance is attributed to the chemisorption of sulfur and oxygen-containing compounds in allicin molecules onto active steel sites, forming stable protective films. This green inhibitor demonstrates excellent potential for sustainable corrosion protection in marine and industrial applications, offering an environmentally benign alternative to synthetic inhibitors.
