Abstract

This research aims to develop and design an Intelligent Tutoring System (ITS) model to improve the efficiency and adaptability of the learning process using technology based on student personalization. This study employs a systematic literature review method, as well as bibliometric analysis and visualization using the VOSviewer application. We collected data from several well-known article databases. The results showed an intelligent tutoring system model to be connected to five components and 22 sub-components. These components consist of a student model, a pedagogical model, an interface model, a tutor model, and a domain model. Thus, these components and sub-components produce a responsive student model that can be used to develop a learning system within the Indonesian National Armed Forces. The responsive student model not only assesses students' visual, auditory, or kinesthetic learning styles but also gauges their emotions or concentration levels during the learning process. This development not only increases learning effectiveness but also improves student learning experiences and supports adaptive and sustainable academic growth.

Abstract

This study evaluated sustained deficit irrigation on the production and quality of plum trees under the semi-arid conditions of the Saïs plain, with four water regimes: T0 (dose practiced by the farmer which may be equal to or greater than 100% ETc), T1 (100% ETc), T2 (80%ETc) and T3 (60%ETc) during the agricultural year 2017/2018. The results of the study showed a significant influence of the irrigation dose on vegetative parameters such as shoot diameter and length, physiological parameters such as leaf temperature, production parameters such as fruit yield per tree and fruit number per tree, and quality parameters such as acidity and sugar content. The fruits grown on T3 (60 %ETc)-treated trees had the highest sugar content. The total acidity of the fruit juice decreased with the increase in sugar content. In summary, the main parameters of vegetative growth, production, and quality were significantly affected by the reduction in irrigation dose. The findings also suggested that a 20% reduction in irrigation dose is feasible without significantly affecting the yield. A bibliometric analysis is conducted on the collected papers on Scopus on sustainable deficit irrigation and its impact on vegetative growth from 1999 to 2023.

Abstract

The duty cycle of pulse width modulation is used to adjust the current of the oxyhydrogen generator with on-off square signals. These signals are essential for an oxyhydrogen gas generator to reduce thermal operation, improve the quality of oxyhydrogen gas, and enhance efficiency. A framework combining particle swarm optimization and regression analysis was proposed to determine the minimum temperature and production time of oxyhydrogen gas while maximizing efficiency using a single input, the duty cycle. The optimization results indicated that the duty cycle for the optimum solution remained within the upper and lower temperature boundaries. In this study, particle swarm optimization successfully provided valuable insights for practical applications in renewable energy technologies.

Abstract

The research questions focused on emerging challenges, solutions, approaches, encryption methods, architectures, and opportunities related to blockchain technology in medical image sharing, and a total of 17 relevant articles were selected from the Scopus database for analysis. The increasing adoption of cloud computing environments in the medical field has raised concerns about security and privacy risks. Within these concerns, problems were identified regarding secure data storage, since centralized storage systems in the cloud mostly lack security effectiveness. Blockchain technology offers a decentralized and secure infrastructure to address these problems. However, a systematic review is needed to identify the strengths and limitations of this technology in this context, therefore the objective of this review is to provide a critical and updated view of the security aspects of the use of blockchain technology in the exchange of medical images in the cloud. The proposed solutions included practical byzantine fault tolerance algorithms, homomorphic encryption, and the integration of smart contracts, among others. In conclusion, this review provides insight into the application of blockchain technology for the secure sharing of medical images in the cloud and identifies key technologies, challenges, solutions, and opportunities in the field.

Abstract

This study investigated the effect of sorbent material on the viability of dried A. pasteurianus starter and the use of defined starter culture of fungi Aspergillus spp, yeast S. cerevisiae, and dried A. pasteurianus starter during purple sweet potato vinegar fermentation.  Complex carbohydrate in cultivation media protects cells during drying, while rice flour as sorbent material absorbs water to obtain dried starter of A. pasteurianus. Increasing the ratio of cultivation media and sorbent material from 1:1 to 1:2 could reduce aw of dried A. pasteurianus starter that will prolong storage time. Mixed starter of Aspergillus spp, yeast S. cerevisiae, and dried A. pasteurianus starter could convert starch to glucose to EtOH to acetic acid during fermentation. However, media saccharified by A. usamii contain lower EtOH and higher acetic acid than media saccharified by A. shirousamii (P0.05). It is noteworthy that A. usamii could hydrolyze starch and protein in rice flour to prevent nutrient exhaustion during acetic acid production by A. pasteurianus. While nutrient exhaustion in media saccharified by A. shirousamii leads to the utilization of acetic acid known as over-oxidation.

Abstract

Tsunami is a catastrophic natural disaster that is difficult to predict and often results in significant loss of life and property damage. This study examines the role of coastal vegetation belts in mitigating tsunami wave impacts through numerical and spatial analyses. This study also used bibliometric analysis to support the discussion. Numerical simulations using CADMAS Surf 2D were conducted for various scenarios to assess the effect of vegetation belts on wave speed and height. Spatial analysis using ArcGIS was employed to map tsunami-affected areas, and grid-cell analysis was used to calculate the volume of water entering inland areas during a tsunami event. The results demonstrate that vegetation belts with specific thicknesses and densities significantly reduce wave speed and height, thereby mitigating tsunami energy as it approaches land. These findings emphasize the critical role of vegetation belts in coastal management strategies. Future research should explore integrating natural barriers with artificial infrastructure, such as embankments, to provide comprehensive protection against tsunami impacts.
