Indonesia has entered a period of demographic bonus. Human resources must be optimized. The number of children who do not in employment, education or training (NEET) in each province needs attention. Several factors that could contribute to the decline in the NEET percentage are literacy rates and the number of adolescents with computer skills. Increasing these two factors is believed to be able to reduce the percentage of NEET in every province in Indonesia. To find out the relationship between these two factors and how much influence they have on the percentage of NEET, this research is modeled by Cauchy regression and includes spatial effects. The results of the analysis show that the best model is when the spatial effect is modeled by Fernandez Steel Skew Normal conditionally autoregressive (FSSN CAR). This result is seen from the smallest value of the Watanabe Akaike Information Criterion (WAIC) in this model, which is 190.5. The parameter estimated shows that the higher the literacy rate and the number of adolescents with computer skills, the lower the percentage of NEET in each province in Indonesia. The results of this research can be useful for the Indonesian government to increase the number of educational facilities related to these two factors. © (2024), (International Association of Engineers).

One of the potential implementations of mobile robots in mitigating the risk of communicable diseases is for delivering items and handling materials with no-human contact. In that scenario, mobile robots require the capability of performing simultaneous multi-object detection and distance estimation for dynamic exploration in a real-world environment. Some existing research papers have contributed to the development of object detection or distance estimation, separately. However, there is still a lack of studies on simultaneous multi-object detection and distance estimation for robot navigation, especially in terms of performance analysis of the integrated techniques. One of the most challenging issues of integrating multi-object detection and distance estimation is the validation and evaluation of the type of objects with their relevant estimated distance to the robot. For that reason, this research aims to analyze the mobile robot's sensing performance in integrated simultaneous multi-object detection and distance estimation during navigation scenarios. A depth camera of Intel RealSense D455 and a rotating LIDAR of Slamtec RPLidar A1M8 are utilized in the experiments. The result of experiments shows that the object detection algorithm using Mobilenet SSD V2 can perform an accuracy of 74%, with precision, recall, and F1-Score consecutively achieving 74,54%, 74,00%, and 74,22%. The multi-object distance estimator also performs satisfactory results with a low measurement average error of 10.3 cm for indoor experiments. The integrated multiobject detector and distance estimator system can work in a real-time mode of 30 FPS, thence significantly improving the navigation performance of the mobile robot.

In the current digital era, virtual reality (VR) technology is rapidly expanding across various fields, including education and cultural preservation. This technology offers immersive opportunities to explore and experience architectural spaces, promising increased understanding and learning motivation. Despite being relatively new in Indonesia, the application of VR has shown significant potential for education and cultural preservation through the implementation of a 3D virtual tour in Kampung Adat Pulo Garut. Therefore, this research aimed to develop VR media to enhance users' spatial experience and preserve the cultural values of Kampung Adat Pulo Garut through interactive learning. The method used was Research and Development (R&D) through the Multimedia Development Life Cycle (MDLC) model. The equipment used was LiDAR Scanner FJD Trion P1 Series, DJI Mavic Air 2S Drone, and Sony A6000 Camera. The method used included aerial and terrestrial mapping, 3D modeling, and the development of virtual environments through Unreal Engine. The developmental process included various stages, namely concept, design, material collection, compilation, testing, and distribution. The result showed an interactive 3D virtual tour of Kampung Adat Pulo Garut, called “Echoes of Tradition.” Unreal Engine was found to enable detailed visualization of traditional architecture and village environments with high accuracy and interactivity. The final product offered an immersive learning experience, enriching users' experience, and enabling digital preservation of cultural heritage. The next step, to get an overview of the research results, used a questionnaire as an instrument which was distributed to a total of 250 respondents. Furthermore, the potential implication of VR in education and cultural preservation was identified, guiding similar applications in the future. By improving accessibility and engagement in spatial and cultural learning, VR offered new avenues in education and cultu

Biomass gasification converts into syngas through the gasification process is promising for renewable energy utilization. Although gasification is a sustainable and environmentally-friendly technology for value-added utilization of biomass, yield percentage is the major problem during biomass gasification. An optimized gasifier and highly active catalyst were proved to be effective for biomass production. Furthermore, the decomposition pathway was also important to advance the gasification reactors and catalyst design. This paper summarized the fundamentals, such as gasifier types, zeolite catalysts, and reaction and deactivation mechanisms. This review also sheds light on other excellent catalysts, effective gasifier, and catalyst reaction mechanisms are also discussed in detail. At last, the paper ends with a conclusion and a prospective discussion of the lab-scale research. At the contact time of 240 minutes, with a column height of 30 cm, at a temperature of 450 oC, the concentration of syngas promise well. © Published under licence by IOP Publishing Ltd.

The synthesis of graphitic carbon nanostructures from cellulose extraction of durian peel waste has been successfully carried out in this study. This study aim to produce the graphitic carbon nanostructures to give innovative solutions to the renewable energy storage challenge. Durian peel cellulose was synthesized into graphitic carbon nanostructures through catalytic graphitization method. 4.8 grams of durian peel cellulose was hydrocharred at 200°C for 4 hours, then impregnated using Fe(NO3).9H2O and ethanol for 90 minutes. The sample was then precipitated for 12 hours and dried at 60°C. The sample was pyrolysed at 900°C for 3 hours. Characterization was carried out using TEM and XRD. Characterization TEM showed the morphological characteristics of graphitic carbon nanostructures in the form of coils in uneven amounts with the avarage diameter size is 24.9134 nm. In addition, the XRD characterization results also strengthen the characteristic phase of graphitic carbon nanostructures at 2θ 26.5° and 44.7°, although nanoparticles from Fe catalysis are visible in the sample due to the absence of reflux. © Published under licence by IOP Publishing Ltd.

ChatGPT has generated significant interest and discussion within the academic community since its initial introduction. This study aims to investigate the students’ intentions to use ChatGPT for educational purposes in higher education. A proposed conceptual model based on the unified theory of acceptance and use of technology model-2 (UTAUT2) was employed in this current study. A total of 575 data obtained from a questionnaire survey of higher education students were analyzed using partial least square-structural equation modeling (PLS-SEM). The results of the hypothesis testing revealed that both cognitive attitude and emotional attitude have a significant influence on the intention to use ChatGPT. The cognitive attitude was influenced by performance expectancy and effort expectancy. Affective attitudes were shaped by factors such as novelty value, performance expectancy, hedonic motivation, and effort expectancy.
