Abstract

Piping systems are a major component in oil and gas processing facilities in Indonesia. With piping usage increasing every year, safety is a critical priority to avoid fatalities and losses due to piping damage. In order to ensure safety and reliability, a thorough analysis of piping stress analysis is required at design and operation stages. Piping stress analysis aims to assess the risk of stresses arising from various factors, including changes in temperature, internal pressure, and external environmental conditions. This study conducted a literature review of 51 international journals published between 2014 and 2024, focusing on factors that affect piping stresses analysis such as force loads, pipe support, piping layout, vibration, earthquake, and cryogenic service conditions. Based on this study, it was found that force load pressure & temperature, determining pipeline layout, pipe support location and vibration have a impact on pipe stress distribution, which in turn affects piping reliability and service life. Analysis using software such as CAESAR II proved effective in identifying critical areas on the piping and ensuring that the system performs in accordance with established safety standards. The review shows that piping stress analysis not only maintains safe operational limits but also improves piping reliability. With proper application of stress analysis, the risk of failure can be minimized, and the service life and reliability of the pipeline system increased. This application is important to maintain production continuity and minimize potential losses due to damage to the piping infrastructure.

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

The widespread practice of reusing Waste Cooking Oil (WCO) in hawker food stalls, often for multiple frying cycles, presents a significant public health concern due to the degradation of the oil, which can lead to the formation of toxic compounds. These practices not only pose health risks, such as increasing the potential for cardiovascular diseases and cancer, but also contribute to environmental pollution when the oil is improperly disposed of. This study seeks to address these issues by converting WCO, along with crude palm oil (CPO), into biodiesel using a custom-designed mini pilot plant. The biodiesel production process involved a two-step reaction. The first step, esterification, was conducted using a 55:100 alcohol-to-oil volume ratio with 1% by volume sulfuric acid (H₂SO₄) as the acid catalyst, at 60°C, with a reaction time of 30 minutes and a stirring speed of 800 rpm. The second step, transesterification, utilized a 6:1 alcohol-to-oil molar ratio, with 1 wt.% sodium hydroxide (NaOH) as the alkaline catalyst, carried out at 70°C over the course of one hour. These conditions were carefully selected to optimize the conversion efficiency and to minimize the free fatty acid content, which is crucial for achieving a high yield of biodiesel. The results demonstrated that the mini pilot plant is highly effective in producing biodiesel from both WCO and CPO. The study also led to the development of a standard operating procedure (SOP) for the biodiesel production process, ensuring reproducibility and efficiency.

Abstract

This study addresses the pressing issue of municipal waste (MW) management by proposing an innovative approach to transform residential solid waste into a valuable resource using green technology. MW, sourced from diverse sectors, undergoes various disposal methods, including incineration, recycling, and landfilling. In Malaysia, the composition of MW aligns with global trends, with food waste and plastic being the predominant categories. This research focuses on producing fertilizer from residential solid waste through a green technology process, utilizing a sequential procedure involving high pressure, high temperature, and energized water to de-polymerize hemicellulose and lignin, followed by microbial enzymatic fermentation. The developed green technology introduces a novel apparatus designed for treating MW in a high-temperature, low-pressure rotating vessel using indirect heating with thermal fluid. The experimental protocol involves four batches of MW samples, evaluating the mass differential before and after the treatment process. Furthermore, a 7-week observation period assesses chili plant growth as an indicator of fertilizer effectiveness. Results indicate a significant 71% mass reduction of MW, amounting to 201.26 kg, emphasizing the efficacy of the developed process. The investigation extends to plant height, comparing MW-derived fertilizer with commercial fertilizer over a 5-week period. Remarkably, chili plants fertilized with MW-derived fertilizer exhibit a greater height of 8.6 cm, surpassing the 7.3 cm observed with commercial fertilizer. This study concludes that MW-derived fertilizer is highly recommended for enhancing plant growth and health in Malaysia, suggesting a sustainable production system. The research not only contributes to waste management but also aligns with broader goals of promoting environmentally conscious and sustainable agricultural practices, emphasizing the potential of green technology in addressing the challenges of municipal waste.
