Comparison of Energy Dissipation in Ogee and Stepped Spillway Using the Fluent Software

/in /by

One of the essential components of any dam is the spillway, which stands as one of the oldest man-made hydraulic structures. It serves as a device designed for the measurement and regulation of water flow, facilitating the controlled passage of excess water and sediment from the upstream to the downstream. This structure finds extensive application in dam construction. Given the critical nature of its function, a stepped spillway demands robust and reliable instruments to ensure high efficiency, ready for use at any moment. Providing crucial information about the behaviour of this significant structure, including flow characteristics such as the flow curve, water level profile, pressure, and velocity pattern at different points of the flow, is essential for its design, monitoring, and safety program. In this research, the Fluent software was employed, utilizing the RSM turbulence mode for simulating the flow on both Ogee and stepped spillways. The comparison of energy loss in these spillways was conducted, employing the VOF model to trace the free flow surface. The obtained results were validated using previous researchers’ studies.

Type of Tourism Attraction and Revisit Intention of Female Traveller

/in /by

This research was conducted with the aim of gathering information on the motivations of female tourists to make repeat visits to Yogyakarta. Women were chosen as respondents because women are considered to have maturity and make better decisions in their families, as well in tourism activities. The research was conducted using a non-probability sampling model on 100 respondents who had finished their trip. The survey was carried out at tourist entry points such as at tourist attraction locations, railway stations and airports. There are three variables tested, namely Perceived Satisfaction of Cultural Attraction (CUL), Perceived Satisfaction of Natural Attraction (NAT), and Perceived Satisfaction of Shopping and Culinary Attraction (ShoC). Using the classic assumption test and multiple linear regression, the results show that female travellers have the intention of making a return visit (RI) because of the satisfaction factor on cultural tourist attraction (CUL) and the satisfaction factor on shopping and culinary attraction (ShoC). The attractiveness of Natural Attraction (NAT) does not significantly influence female travellers having intention to revisit.

The Implications of Lean Thinking in Digital Transformation Projects

/in /by

The Internet of Things, Data Science, 3D printing, Artificial Intelligence and Machine Learning are some elements on the agenda related to business modernization. These and other digital technologies promote significant changes in the structures of organizations, from strategic planning to the factory floor. However, this process of Digital Transformation is not only materialized in the implementation of digital technologies in the production chain, but is based on the capacity of these enabled technologies to generate new value propositions. This article proposes a discussion about the implications of Lean Thinking in the implementation of Digital Transformation projects. For this, the study analyzed 21 international academic works, from the year 2018, based on the Web of Science and Scopus repositories. The repositories were selected because they are comprehensive and offer intelligent search tools. After a systematic analysis of the documents, a discussion arose about the central elements capable of expanding the understanding of the components of Lean Thinking and its relationship with Digital Transformation projects.

The Correlation between Self-Confidence and Social Anxiety among Secondary and High School Students in Bangkok, Thailand

/in /by

Social anxiety disorder (SAD) is a debilitating condition characterized by a marked and persistent fear of being humiliated or scrutinized by others. It is the third most common mental health disorder and has its origins in adolescence. Accordingly, social relationships are particularly challenging for socially anxious adolescents. Therefore, we assume that self-confidence, which represents your belief in your own abilities, capacities, and judgments, plays an important role. This research aims to explore whether there is a correlation between self-confidence and social anxiety. It also aims to determine differences in selfconfidence and social anxiety according to age and grade. Individual data from 222 participants were collected using an online questionnaire that included general information, a self-confidence section, and a social anxiety section. The participants were secondary and high school students in Bangkok, Thailand. The collected quantitative data were analyzed using Pearson’s correlation coefficients and independent sample t-test within the Statistical Package for the Statistical Product and Service Solutions (SPSS) version 29 program.

The results indicate a significant correlation between self-confidence and social anxiety at the .01 level. Additionally, self- confidence did not show significant differences according to grade or age. The results also revealed that social anxiety does not significantly change based on grade or age.

Improving the Quality of Functional Food Crops and Land Efficiency by Intercropping System on Application of Integrated Fertilizer

/in /by

The intercropping system and integrated fertilizers were applied in the research to improve land efficiency and the quality of sweet corn and vegetable soybean crops. The study was conducted in the Giwangan Village of Umbulharjo Yogyakarta, Indonesia, and was set up using a three-replication factorial Randomized Complete Block Design. Three organic fertilizer sources (cow manure, chicken manure, and composted waste) made up the first factor, and the second factor was NPK fertilizer doses (200, 300, and 400 kg ha-1). Two control treatments were also made, which resulted in 33 experimental plots. The observed data were subjected to analysis of variance and Duncan’s Multiple Range Test at a significance of 5%. The study’s findings demonstrated that the combination of 300–400 kg ha–1 NPK fertilizer and chicken manure increased variables such as the content of vitamin C and pro-vitamin A, number of seed rows, number of 2-3 seed pods, and sweetness level of soybean and sweet corn, as well as the land equivalent ratio, land equivalent coefficient, competition index, system productivity index, and relative yield mixture.
