Published: February 2024

Improving airfoil aerodynamic performance is an essential aspect of aerodynamic technology. The use of passive flow control is one way to enhance the aerodynamic performance of the airfoil. The influence of using gurney flaps as passive flow control was explored through the CFD approach employing the RANS control equations with the k-epsilon turbulence model. The airfoil model utilized in this investigation was the NACA 4415 operating at a Reynolds number of 1×106. This study explored three different variations of flap height, namely 0.5%, 1%, and 2% of chord length. The outcomes showed that adding gurney flaps showed quite positive results in increasing the lift and drag performance of NACA 4415. An airfoil with a 0.5%c height flap has an average percentage increase in Cl of 12%, followed by a height flap of 1%c, which is 23%, and a percentage Cl of 37% for a height flap of 2%c. Meanwhile, each variation in height flap affected the increase in Cd. A height flap of 0.5%c increased Cd with an average percentage of 2%, while a height flap of 1%c increased the percentage of Cd by 4% and 6% for a height flap of 2%c. Moreover, visualization of fluid flow with pressure and velocity contours given at AoA 12º to determine the effect on the increase in Cland Cd in NACA 4415.

Published: February 2024

Electrical energy's significance is critical to human life, as seen by the rising usage of this resource. Electricity-consuming machinery and technology are developing at an accelerating rate. A substantial electrical power supply is required to achieve these requirements. An effective method to address this issue is to use a generator set powered by an electric motor. This generator necessitates the use of a converter, which serves the purpose of transforming alternating waves (AC) into direct waves (DC), generally referred to as a rectifier. The rectifier's unsatisfactory performance necessitates the need for this research, which seeks to develop and construct a rectifier and subsequently compare its performance utilizing two distinct current sources. Rectifier performance is obtained through the utilization of direct computation and measuring methods. Two sources charge the battery: direct current from the motor and alternating current from the power grid. According to the test results, the converter using an electric power plant source had a higher current value. On the generator, the battery charges up to 13.4 volts in 55 minutes, which is 5 minutes quicker than on the PLN source.

Published: February 2024

Airfoil that experiences erosion caused by flying debris that hit the airfoil can affect the performance of the airfoil. This research was studied to determine the effect of erosion with varying erosion length using numerical methods on the performance of the NACA 0015 airfoil. This research was simulated using the Computational Fluid Dynamics (CFD) approach. Reynolds Averaged Navier-Stokes (RANS) is implemented as the governing equation. The turbulence model used in this research is the k-epsilon model. The Reynolds number used is 1.5 x 10⁶. This research proves that the erosion effect can reduce the Cl value and increase the Cd value on the NACA 0015 airfoil. Increasing the erosion length on the airfoil can also affect the Cl value and Cd value, but this effect is insignificant. In the contour visualization, it can be seen that the airfoil that is experiencing erosion has a pressure contour that increases in the upper chamber and decreases in the lower chamber compared to the airfoil that does not experience erosion so that it can reduce the lifting force of the NACA 0015 airfoil. The flow velocity and streamline contours also show greater circulation in the erosion airfoil, which can accelerate the stall by 1o AoA. Then, variations in increasing erosion length on the airfoil do not show any significant differences in pressure contours or circulating flow.

Published: February 2024

In architectural planning, natural lighting systems need to be considered. With the right program, natural light has an impact on occupant productivity and satisfaction. Controlling lighting use is necessary to manage the glare effect in the room, in addition to its advantages in terms of energy efficiency. The application of minimalist facade systems without additional shading elements is increasing in number, and the form is increasingly minimalist. Minimalist facade designs are not suitable for use in tropical countries with abundant sunlight. Apart from increasing the cost of electrical loads, sunlight penetrating buildings through transparent walls or glass also causes a glare effect in space. Therefore, it is necessary to study and implement the lighting system correctly to ensure a high-quality room atmosphere. The research method uses a mixed-methods approach, carried out using an explanatory sequential strategy. The analysis process begins with a qualitative research stage, followed by quantitative research. Research data was obtained from literature studies, observations, and interviews with planners, owners, and residents. The simulation results showed that the installation of shading (horizontal, vertical, and combined) on the west side, following the SNI no. 03-2396-2001 method to reduce glare, did not decrease the value of light exposure received by the building mass of the Smith building. Based on the activities conducted, measurements on units that are already operational, and which are still in standard condition have informed us that proper interior implementation contributes to decreasing light intensity values in office, SOHO, and apartment spaces

Authors: Dino Rimantho
Published: February 2024

The development of wood pellets as a sustainable energy source derived from biomass waste has not significantly increased over the past few decades, despite a rise in demand for and sales of its products worldwide. Several variables contribute to the intricate issue of creating wood pellets from biomass waste as a renewable energy source, including the roles and responsibilities of various stakeholders, including the government, financial institutions, academia, the manufacturing sector, and non-governmental organizations. This article uses a waste management model that employs the Soft System Methodology (SSM) approach to assess the challenge of producing wood pellets from biomass waste as a renewable energy source and possible solutions. Data and information on the development of wood pellets as a renewable energy source derived from biomass waste were acquired through a literature review and in-depth interviews with specialists. The study’s findings demonstrate that using the SSM technique leads to a conceptual model that depicts the interactions between sub-elements to enhance the development of wood pellets as a biomass waste-derived renewable energy source. This concept was developed to lessen any adverse effects and enhance the processing of biomass waste. The success of goals is determined by the importance of each actor’s role and the collaboration of other actors, including local, national, and corporate governments. The Ministry of Environment and Forestry is the primary stakeholder and has a say in policy and program formulation. The Ministry of Industry, Energy and Mineral Resources, financial institutions, and other relevant organizations can help with this effort.

Authors: Nakajima Yusuke , Takashima Akira , Noguchi Masaki , Isogai Tatsunori
Published: February 2024

Aluminum oxide (Al2O3) films were fabricated through the oxidation of ultrathin aluminum nitride (AlN) films. The fabricated films exhibited a leakage current reduction compared to that of conventional Al2O3 films fabricated using atomic layer deposition. This reduction in the leakage current can be attributed to the formation of θ-Al2O3, which has a wider-bandgap than γ-Al2O3. The formation of θ-Al2O3 was attributed to the residual stress caused by the oxidation of the AlN thin films.

The addition of N-BzHoA suppressed the formation of unwanted PbI2 and δ-phase perovskite without affecting the band gap, confirming uniform and large grains in the perovskite film. The fabricated inverted PVSCs exhibited remarkably improved properties compared to the control device, with a power conversion efficiency of 17.49%, reduced hysteresis, and more than 89% retention of the initial capacity after 100 h of light exposure. Thus, this study highlights the effectiveness of N-BzHoA as an effective additive for inverted PVSCs.

Large data sets are essential for building deep learning models. However, generating large datasets with higher theoretical levels and larger computational models remains difficult due to the high cost of first-principles calculation. Here, we propose a lightweight and highly accurate machine learning approach using pre-trained Graph Neural Networks (GNNs) for industrially important but difficult to scale models. The proposed method was applied to a small dataset of graphene surface systems containing surface defects, and achieved comparable accuracy with six orders of magnitude and faster learning than when the GNN was trained from scratch.

Objective: The study aimed to investigate the reliability of ChatGPT’s answers to medical questions, including those sourced from patients and guide recommendations. The focus was on evaluating ChatGPT’s accuracy in responding to various types of infectious disease questions.

Materials and Methods: The study was conducted using 200 questions sourced from social media, experts, and guidelines related to various infectious diseases like urinary tract infection, pneumonia, HIV, various types of hepatitis, COVID-19, skin infections, and tuberculosis. The questions were arranged for clarity and consistency by excluding repetitive or unclear ones. The answers were based on guidelines from reputable sources like the Infectious Diseases Society of America (IDSA), Centers for Disease Control and Prevention (CDC), European Association for the Study of Liver Disease (EASL) and Joint United Nations Programme on HIV/AIDS (UNAIDS) AIDSinfo. According to the scoring system, completely correct answers were given 1-point, and completely incorrect ones were given 4-points. To assess reproducibility, each question was posed twice on separate computers. Repeatability was determined by the consistency of the answers’ scores.

Results: In the study, ChatGPT was posed with 200 questions: 107 from social media platforms and 93 from guidelines. The questions covered a range of topics: urinary tract infections (n=18 questions), pneumonia (n=22), HIV (n=39), hepatitis B and C (n=53), COVID-19 (n=11), skin and soft tissue infections (n=38), and tuberculosis (n=19). The lowest accuracy was 72% for urinary tract infections. ChatGPT answered 92% of social media platform questions correctly (scored 1-point) versus 69% of guideline questions (p=0.001; OR=5.48, 95% CI=2.29-13.11).

Conclusion: Artificial intelligence is widely used in the medical field by both healthcare professionals and patients. Although ChatGPT answers questions from social media platforms quite properly, we recommend that healthcare professionals be conscientious when using it.

Stunting is a problem that threatens the quality of human resources in the future. This problem of chronic malnutrition is caused by a lack of nutritional intake and failure to achieve development and growth both physically and cognitively as measured by height for age. This research aims to explain the relationship between family support and the incidence of stunting. Data collection carried out in this literature review used a literature search method from national and international articles using the ScienceDirect, Google Scholar and Pubmed databases. An initial search using the keyword: “Child Stunting Family Support” yielded 9,924 articles from 2018 to 2023 that met the inclusion criteria. Based on the results of the literature review, it was found that family support has a significant relationship with the incidence of stunting because good family support is considered capable of creating an optimal environment so that risk factors for stunting can be minimized. Family support is specifically provided in four ways through emotional, informational, instrumental, and assessment or appreciation support. Stunting prevention can be done through strengthening family support in a complex manner through the implementation of emotional support, information support, instrumental support, and good assessment or appreciation support for the mother. By implementing this family support, health behavior will be created that can provide greater opportunities to fulfill children's needs so that they do not experience stunting.
