<span lang="EN-US">A good and proper street lighting system on campus indirectly supports teaching and learning activities. However, these conditions still need to be developed at the Marine and Fisheries Polytechnic of Kupang due to the lack of these facilities. Therefore, a solar street lighting system was designed considering the good potential of solar energy in this region. The design of this system is carried out by measuring for a year, analyzing the energy potential, economics of the system, and the social impact of installing the system. The installation of solar street lighting on campus based on the results of an analysis of technical, economic, and social aspects gives good and feasible results. The results from the technical aspect provide that the utilization of this system provides a PR value of 85%, and can make savings of 15.99 MWh per year, and provide energy of 177.8 kWh per year. The results from the economic aspect of using this system provide an IRR value of 6%, SPBP for 8.93 years, and a net present value (NPV) of IDR 85,247,500.56. The results of the social aspects obtained from the respondents’ answers showed different and meaningful results (p<0.05) from all categories given to respondents.</span>

“…We acknowledge that without measurements for other supporting variables, the process of connecting why the effects of training status lead to apparent changes in body composition variables becomes challenging to comprehend. Nevertheless, these differences in response to resistance training stimuli, particularly regarding changes in weight, BMI, and body fat percentage between untrained and trained populations can be attributed to various factors such as differences in BMR, the floor-ceiling effect, and sensitivity to training stimulus responses as indicated by available literature sources (Farhana & Rehman, 2021;Souza, Barbalho, & Gentil, 2020). Studies by Poehlman, Melby, and Goran (1991) indicates that the resting metabolic rate in trained populations is higher compared to untrained populations, implying that trained individuals require significantly more energy.…”

Background. Resistance training is an effective form of exercise that promotes healthy body weight regulation and enhances flexibility. However, discrepancies exist regarding the varying impacts of resistance training based on individuals’ training status across different fitness components, such as body composition and flexibility. Objectives. The primary objective of this study is to assess whether there are significant differences in the outcomes of resistance training responses between trained and untrained groups concerning body composition and flexibility. Materials and methods. This experimental resistance training study involved 60 male students (age = 20.83 ± 0.85 years old) from the same university. The participants were divided into two groups based on their training status: a trained group (S; n = 30) and an untrained group (NS; n = 30). Both groups underwent an identical training regimen, consisting of three sessions per week over a total of four weeks or 12 training sessions. Results. Significant differences were observed in the paired sample T-test analysis between pre-test and post-test results in the untrained group for body weight (t (29) = 7.940, p < 0.001, d = 1.45), body mass index (t (29) = 7.579, p < 0.001, d = 1.38), body fat percentage (t (29) = 9.733, p < 0.001, d = 1.77), and sit-and-reach flexibility (t (29) = -7.714, p < 0.001, d = -1.40). Similarly, the trained group showed significant changes in body weight (t (29) = 2.644, p = 0.013, d = 0.483), body fat (t (29) = 2.561, p = 0.016, d = 0.351), and flexibility (t (29) = -2.543, p = 0.017, d = 0.351), while no substantial difference was found in body mass index (t (29) = 1.925, p = 0.064, d = -0.464). Conclusion. The study found that using resistance training protocols targeting weight reduction with 60-70% of 1 Repetition Maximum (RM) over a one-month intervention period, without stringent calorie restriction, significantly decreased weight and BMI while enhancing flexibility. Notably, regardless of training status disparities, the untrained group demonstrated more expressed improvements compared to the trained group, indicating the influence of training status on response variations to training stimuli.

“…While comparing High-Pressure Sodium and LED was, it is clear that Power consumption cost of LED is less than the power consumption cost of High Sodium Lamps [8] In another case study in Qatar, ME2 represents urban areas lighting class with 30 miles per hour as speed limits and have high end pedestrian activity including zebra crossings.ME3a represents 40 mph or less speed limit, parking is restricted at peak times and there are positive measures for pedestrian safety reasons. The case study in this paper was conducted for 6 km road project using Dialux 4.9 software [9,15].An important aspect of road surface lighting is how much it can improve pedestrianvisibility [13].…”

This paper briefly describes street lighting design and the standard requirements of lighting design in particular reference to UAE. The photometric parameters for different types of roads in Abu Dhabi is analysed and simulated using DIALux. The results are in agreement with the standard requirements. A realtime scenario has been done using cross section developer tool for different streets in Abu Dhabi. Simulation results have been compared with CIE and IESNA standards. In the analysis phase, photometric behaviors including chromaticity coordinates, S/P ratio, CRI, CCT values of different luminaires were compared. Higher CCT accounts for increased alertness in sleep. The proposed methodology shall motivate lighting design aspirants to balance efficient design along with sustainability.
