Global Sustainability Towards Future Development Results and Discussion Our study's findings reveal that a rectangular structure model measuring 3.5 cm x 3.5 cm x 45 cm, with a separation distance of 20 cm, significantly impacts key parameters in an open channel. Examining the graph readings, we observe a notable change in the relationship between two main parameters: the ratio y2/y1 versus Froude Number (Fr) and the comparison of Q against Energy Loss. Firstly, analyzing the y2/y1 against Fr graph indicates a continuous decrease. This suggests that the rectangular structural model negatively affects the water depth, measured by the y2/y1 ratio, in correlation with an increase in Fr. This phenomenon signifies a change in water height along the open channel, with the square structure model lowering flow velocity. Secondly, examining the Q graph against Energy Loss reveals a clear increase. This implies that the square structure model with a 20 cm stack spacing leads to a rise in energy loss in the open channel. This phenomenon is attributed to the barrier created by the square structure, causing increased friction and energy loss in water flow. Discussing these study results deepens our understanding of how the rectangular structural model influences crucial parameters in open channels. While the square structure model can reduce velocity, it simultaneously results in increased energy loss. Therefore, addressing the negative impact on velocity requires a balance with the goal of optimizing energy efficiency in open channels. Conclusion Specifically, a rectangular structure model with a size of 3.5 cm x 3.5 cm x 45 cm with a distancearrangement (spacing) of 20 cm has produced graph readings that achieve the highest performance. Resultsthis shows that the configuration gives the most positive impact inreducing velocity in open channels, strengthening their effectiveness and relevancein the context of this study.Thus, the selection of the specific size and arrangement of the square structure modelbe the main emphasis in the pursuit of optimal results. This conclusion leadsa sharper emphasis on experimental results, presenting facet structure modelsfour as approaches that have the potential to provide practical solutions to problemsvelocity in an open channel.

Global Sustainability Towards Future Development Mengkaji Masalah Perpaipan Dan Kualiti Air Di Blok A Asrama Lelaki Politeknik Mukah Ahmad Shahril Bin Mohamad Shahudin1,* , and Nathanel Salo Lisut2 1,2 Department of Civil Engineering, Politeknik Mukah (of Affiliation) *Corresponding author: [email protected] Abstract The study conducted in Block A of Politeknik Mukah aimed to investigate plumbing issues and assess water quality. The research, carried out at the Block A dormitory, focused on identifying water pollution effects, determining pH and turbidity values, and studying water pressure. Parameters for water quality assessment included pH and turbidity tests conducted at Sarawak University of Technology's environmental laboratory, while water pressure tests were performed on-site. The study area was subdivided into five locations: tap water levels 1 through 5. Water samples from Block A were analyzed at the Sarawak University of Technology's environmental laboratory. Results indicated that the water quality in Block A of Politeknik Mukah was classified as level III, indicating cleanliness but unsuitability for drinking due to water being channeled through a tank. The pH value test was identified as a significant factor affecting water quality at level III. The study underscores the necessity for improvements, given that the water from Block A serves various daily purposes such as bathing and drinking. Keywords: - plumbing issues, water quality assessment, water pollution effects, pH values, turbidity values, CP02 39 Introduction he availability of clean water in Block A of the Mukah Polytechnic male dormitory is crucial for daily tasks like bathing, cooking, drinking, and washing clothes. However, plumbing issues, including low water pressure, lead to frequent water shortages and a decline in water quality, causing it to appear cloudy. Adequate water supply is essential for male students residing in Block A to carry out their daily activities, posing a significant challenge due to these issues. Many complaints have been recorded from male students in Block A through a virtual Google Form questionnaire. This research focuses on Block A of the Mukah Polytechnic male dormitory. The study involves collecting data by visiting the area and taking water samples for testing at the Mukah Polytechnic laboratory, aiming to evaluate the water quality in Block A. Methodology Figure 38 : Flowchart PRODUCT EXTENDED ABSTRACT
Global Sustainability Towards Future Development Results and Discussion The results found that pH at all level are range 7 – 8. There are still cloudy readings on levels 2 and 3 of the block. Levels 3, 4 and 5 experience very low water pressure readings compared to levels 1 and 2. Conclusion People need good water to live their daily life because of their needs. Water is a very important resource, so it should be healthy and clean. Water has many uses as well. For example, water is used for many purposes, including cooking, bathing, drinking, and washing clothes. The PH value of quality water is 7, and the color and smell of the water can be identified because it is clear and odorless. Therefore, the aim of this study is to determine issues related to plumbing and water quality in block A of Mukah Polytechnic male dormitory, as well as to test the water pressure in Block A of Mukah Polytechnic Acknowledgment We are grateful to the respondents and participants who willingly provided their time and input, essential for the data collection and analysis processes.
