Abstract

Traditional classroom settings often present significant challenges for children with autism spectrum disorder (ASD) in terms of communication. Specialized classrooms designed for children with ASD, such as those based on the Autism Design Index (ASPECTSS), incorporate specific principles and approaches including navigation patterns, lighting, and color. This study aimed to evaluate the effectiveness of classroom designs based on the ASPECTSS in improving communication skills and academic achievement of students with ASD. Employing a mixed-methods approach, this study compared the responses of students with ASD in two different classroom conditions. The results indicated that students with ASD responded more positively to classrooms designed based on the Autism Design Index ASPECTSS, as evidenced by increased verbal communication frequency, attention span, and academic performance. These findings suggest that physical classroom design tailored to the sensory and cognitive needs of students with ASD can serve as an effective intervention to support their learning. This study recommends that schools adopt ASPECTSS principles when designing inclusive classrooms to create optimal learning environments for all students.

Abstract

This study presents a comparative analysis of prepaid and postpaid kilowatt-hour (KWH) meters in improving the accuracy of electricity consumption measurement among customers of the PT PLN Customer Service Unit (ULP) in Langsa City. The study aims to determine whether prepaid KWH meters, which require users to pay for electricity prior to consumption, provide billing and usage monitoring accuracy comparable to traditional postpaid systems, where payments are made after electricity consumption based on meter readings. The methodology used involves a detailed examination of meter readings from two different groups of consumers over a one-month period, coupled with an assessment of the impact of meter type on consumer payment behaviour and incidents of electricity theft. The results indicate significant differences in the accuracy of electricity consumption measurement between the two meter types, with prepaid meters demonstrating a potential for reducing electricity theft and improving consumer energy management through upfront payment mechanisms. In addition, the study examines the technical and psychological factors that influence consumers' energy consumption patterns, highlighting how prepaid meters can encourage more controlled and conscious use of electricity. This analysis provides valuable insights for utilities considering the implementation of prepaid systems to improve billing accuracy, reduce operating costs and promote sustainable energy consumption behaviours among consumers.

Abstract

Cd(II) metal ions are commonly found in water bodies and are non-essential and carcinogenic, leading to lung cancer. Thus, it is crucial to remove Cd(II) metal ions from water. Adsorption is one effective separation method due to its relative simplicity and cost-effectiveness. In this work, the adsorption kinetics study of Cd(II) metal ions using PVA.cl.GA-TSC were examined. Polyvinyl alcohol (PVA) was crosslinked with glutaraldehyde and subsequently modified with thiosemicarbazide (TSC). The resulting PVA.cl.GA-TSC was characterized using FTIR. The adsorption process was carried out in a batch system at room temperature. The study revealed that the adsorption kinetics of Cd(II) metal ions with PVA.cl.GA-TSC followed a pseudo-second-order kinetic model, with a rate constant of 0.4 × 10⁻³ g.mg⁻¹.min⁻¹. In the kinetics data, an intra-particle diffusion model was also performed to understand the adsorption reaction mechanism. The intra-particle diffusion model indicated that the rate-determining step was governed by the intra-particle diffusion stage, with a rate constant of 0.387 mg.g-1min-1/2.

Abstract

Mini hydro power plants (PLTM) are capable of producing electricity continuously for 24 hours. The amount of energy distributed by the Mini Hydro Power Plant (PLTM) is greatly influenced by the strong flow of water coming from upstream, so the effect of rainfall is relatively direct on the electricity produced by the Karo Bumi Energi Mini Hydro Power Plant (PLTM) with a capacity of 2 x 4, 85 MW. From the observations, rainfall is a dry month, it can also be seen that rainfall, water discharge and production are directly proportional. In May, June and July there is a very significant difference between production and water discharge. According to observations, these months are wet months with very high rainfall. The resulting productivity of hydropower plants is influenced by the creation and release of stable water without aggravation. The higher the creation and release of water, the higher the efficiency of the power supplied. The impact of high rainfall will cause the water release to reach 11,653m3 / hour

Abstract

Litter is a very disturbing object in the environment. Public awareness of waste management is still minimal. The government, together with several communities, has tried to utilise it, but waste accumulation remains a significant problem. Entertaining educational efforts are needed to help the public understand proper waste management. In line with the government's programme to promote the use of new and renewable energy, waste can be used as renewable energy, depending on its classification. This research aims to create an entertaining and accessible educational model application in the digital age that utilises waste as renewable energy based on educational games. Tests were carried out using classical statistical tests, including validity tests, reliability tests and Spearman correlation tests. The results obtained from the questionnaires given to the users who completed the trial showed that 4 items were not valid: Q4, Q18, Q29 and Q31. The results of the reliability test showed that out of 28 data tested, the value was very high at 0.946. The correlation test concluded that learnability is correlated with memorability and satisfaction, while satisfaction is correlated with errors

Abstract

Based on the latest data for 2022-2023, climate change-related natural disasters in Indonesia have increased quite significantly. Climate change is caused by high levels of greenhouse gases (GHG) accumulating in the atmosphere. Surabaya, the second largest city in Indonesia, contributes a high amount of GHG, while Indonesia has committed to efforts to reduce greenhouse gas emissions, which will result in a reduction of greenhouse gas emissions by 29% in 2030. Energy transformation is an alternative. It is important to support it, but society needs to prepare to implement the transition to a modern, reliable and low-carbon energy system globally. At least three factors are driving the energy transition: environmental, social and economic. Therefore, the research was carried out by analysing social impact projections using quantitative questionnaire methods. The energy transition has an impact on social aspects, as shown by the percentage of public acceptance of 75.11%. The level of acceptance by the people of Surabaya City regarding the impact of energy transformation is quite high with a percentage of 83.02%
