The purpose of this research to explore the impact of parental involvement on the academic achievement of students at Crescent International School and to determine whether the demographic variable of parents has an effect on their involvement in their children's education. In addition, the study sought to examine what existing literature review found on the relation between parental involvement and children's academic achievement. The present study was carried out at Crescent International School in Bangkok, Thailand. The responses of 12 parents, whose children are enrolled in secondary level, were taken as samples for the current study. The Intensity Sampling Technique was used in this research. A questionnaire about demographics of parents was distributed and interviews were conducted to assess the level of parent involvement. To find out student achievement level, the students results were used. The qualitative method was used to gauge the impact of parental involvement on students' academic achievement. The results revealed that parental income level has no impact on the level of involvement in their children's education. However, educational level, age, employment and marital status of the parents had greater impact on parental involvement. The main findings of this research indicated that students with highly involved parents had better academic performance and higher test scores in all the subjects compared to students whose parents were not involved in their education. the findings, suggested that parents should grow more awareness on the importance of visiting and supporting their children in school. It was also recommended that parents should take an active role in assisting their children's education at school and at home since they are the first teachers of their children.

Conductivity (EC) and total dissolved solids (TDS) are water quality parameters, which are used to describe salinity level. These two parameters are correlated and usually expressed by a simple equation: TDS = k EC (in 25 °C). The process of obtaining TDS from water sample is more complex than that of EC. Meanwhile, TDS analysis is very important because it can illustrate groundwater quality, particularly in understanding the effect of seawater intrusion better than EC analysis. These conditions make research in revealing TDS/EC ratios interesting to do. By finding the ratio value, TDS concentration can be measured easily from EC value. However, the ratio cannot be defined easily. Previous research results have found that the correlation between TDS and EC are not always linear. The ratio is not only strongly influenced by salinity contents, but also by materials contents. Furthermore, the analysis of TDS concentration from EC value can be used to give an overview of water quality. For more precision, TDS concentrations need to be analyzed using the gravimetric method in the laboratory.

Plastics have been produced and used by humans in large quantities since they were invented, and the resulting environmental pollution problems have become more and more serious. In recent years, researchers have found that many plastic products are not completely decomposed after being discarded, a lot of plastics form microplastics in the ocean, which poses a threat to the survival of marine life. This paper analyzes the source, types and distribution of marine microplastics, and explores the influence of microplastics on marine life.

In this paper, we examine existing literature on the way that the number of blades of a wind turbine affects its efficiency and power generation. A wind turbine blade is an important component of a clean energy system because of its ability to capture energy from the wind. The power that a wind turbine extracts from the wind is directly proportional to the swept area of the blades; consequently, the blades have a direct effect on power generation. The number and configuration of the blades is very important because it affects the speed and efficiency of turbine. Unfortunately, as the number of blades increases, so does the slipstream effect. Too few a number of blades results in poor efficiency and thus inadequate performance. Too large a number of blades increases weight and production cost. The correct number of blades is important to fit the generator performance curve to optimize overall turbine performance and efficiency.

Tesla's rapid rise to become one of the world's most influential automakers has marked the start of a new era in the global automobile industry, where many of the traditional auto companies were overshadowed by Tesla's dominance. Judging from Politics, Economy, Society and Technology perspectives, Tesla's market value can potentially be overvalued due to its leading role in the Electrical vehicle market. Economically, Tesla facilities the growth of global economy by creating more employments and manufacturing factories. Socially and politically, Tesla's Electrical Vehicle reduces the level of negative externalities (e.g., pollution), which aligns with the developmental frameworks proposed by governmental policies and regulations. Meanwhile in technological aspect, Tesla pioneers the innovative design of battery pack to reduce the overall cost of battery and seeks to integrate better automatic driving system into electrical vehicle. Given those merits of Tesla, overoptimism on its stock price is expected. Therefore, it is important for stock traders who are willing to throw money at Tesla to ruminate over their choices before making the investment. In this study, the results of valuation methods indicate that true market value of Tesla has been overestimated due to its irregularly high operating cash flow, price-to-earnings ratio and enterprise value to earnings before interest, taxes, depreciation, and amortization ratio, suggesting its stock price is overvalued.

Outdoor lighting has been dimmed or turned off in European municipalities due to the energy crisis. Dimming of outdoor lighting levels led to energy savings, advantages for biodiversity and less light pollution. But the dimming also triggers the basic human assumption that bright light is connected to safety and darkness is connected to fear. To discuss this basic assumption, human experience of dimmed lighting and perceived safety is explored through three case studies. One study explores human experiences of dimmed street lighting during energy crises, the second study investigates dimmed lighting levels around public transportation, and the third study is an example of a context-specific adaptation of street lighting in a residential area. The case studies reveal that dimmed lighting levels, minimized contrasts, and context-specific lighting can lead to an increased connectedness to the spatial and social urban context and an increased feeling of perceived safety. Thus, more light doesn't always lead to more perceived safety. With a dimmed general lighting level, it is possible to introduce additional subtle lighting layers, structured in a lighting hierarchy to further enhance spatial and social qualities in outdoor contexts in the dark hours. in constructing both.

Waste disposal is one of the important problems in the world. In general, wastes are categorized into different groups, and there are some special landfills and methods for disposing of each of these waste materials. However, it should be noted that although there are some rules and regulations that try to reduce the impact of waste disposal, landfills have negative effects on soil, air, water, and natural life. One of the most important sources of pollution in landfills is the leachate that is generated by the decomposition of waste. Leachate can penetrate into the soil and water resources, contaminate them, and can affect human life. Leachate generation has five different phases and each of these phases contains some reactions that have a direct impact on the quality and quantity of leachate. Leachate has four main types of pollution and each of these pollutants can contaminate soil and water resources and be hazardous for aquatic and animals in the soil. In addition, some of these contaminations can enter the food chain and affect the ecosystem and human life. The negative impacts of landfills remain even years after the landfill is closed. Therefore, it is important to consider the short-term and long-term effects of landfills on their surroundings to protect the environment and human health.

The large demand for cayenne pepper makes farmers need to make efforts to increase crop production by increasing the efficiency of using fertilizers. The alternative fertilizer comes from household waste, namely egg shells. This study aims to determine the effect of eggshell organic fertilizer on vegetative growth of cayenne pepper (Capsicum frutescens L.). The research method used was an experimental method using a completely randomized design (CRD) with 6 treatments and 5 replications. The treatments were P0 (control), P1, P2, P3, P4, and P5 respectively, the treatment of eggshell organic fertilizer with a dose of 0; 45; 60; 75; 90; and 105 g. The treatments were given 3 days after transplanting and harvesting the plants 35 days after transplanting. Data for each parameter was tested for normality, homogeneity test, and analyzed by 1 factor ANOVA. Furthermore, the LSD test was carried out to determine the difference in effect between treatments. The best application of eggshell organic fertilizer was P4 treatment for parameters of root length and plant wet weight, respectively, 20.10 cm and 17.96 g, and P5 treatment for parameters of plant height and plant dry weight, respectively 54.80 cm and 3.00 g. The percentage of root length and wet weight of P4 treatment plants to control were 130.52% and 269.67%, respectively, while the percentage of plant height and dry weight of P5 treatment plants to control were 139.79% and 282.49%, respectively. The application of eggshell organic fertilizer can increase the vegetative growth of cayenne pepper.

In recent years, under the double pressure of energy exhaustion and environmental deterioration, the development of electric vehicles has become the major development trend of the automotive industry in the future. This paper discusses the problem of abandoned batteries caused by the limited life of a large number of batteries with the prosperity of new energy vehicle industry. This paper lists and analyzes the different characteristics of batteries commonly used by three new energy vehicles in the market :(1) lead-acid batteries will not leak in the use process due to tight sealing, but their use cycle is very short. (2) The production of nickel metal hydride battery is relatively mature, its production cost is low, and compared with lithium electronic battery is safer. (3) Lithium-ion batteries are made of non-toxic materials, which makes them known as "green batteries". However, they are expensive to make and have poor compatibility with other batteries. Because discarded batteries pose a threat to human health and environmental sustainability, lithium-ion batteries may overheat and fire when exposed to high temperatures or when penetrated, releasing carbon monoxide and hydrogen cyanide that can be very harmful to human health. In addition, waste batteries will also cause water pollution and inhibit the growth and reproduction of aquatic organisms and other potential dangers. Therefore, it is necessary to recycle it efficiently. This paper then introduces the advantages of three recycling methods: step utilization and recovery, ultrasonic recovery and sodium ion battery. These recycling methods can maximize the reuse efficiency of waste batteries. This paper expects to find a better way to recycle waste batteries to solve the potential problems of improper disposal of waste batteries and reduce the environmental hazards of waste batteries.

Life as we know has experienced significant changes since the COVID-19 pandemic. This is clearly apparent in urban society, where urban dwellers have needed to adapt to changes in their everyday lives. These changes impact our perceptions of the city and how we support urban adaptation post Covid-19. The "healthy and livable" urban paradigm is not just a theoretical idea anymore but is now a necessity in urban development.

This paper aims at determining the heterogeneity effect of rail network connectivity influence on regional economic growth in West Java Province employing a multiple linear regression analysis approach to panel data covering 27 districts/cities in 2010-2018. There are several variables that are used as input variables for analysis such as GRDP per capita (PDRBPKit) as the dependent variable, connectivity (Konektivitasit) as the independent variable, and economic variables (Public Government Investment per capita (invpit); Private Investment per capita (invsit); Human Capital (ipmit); Agricultural Contribution (agricultureit); Industry Contribution (industriit); Service Contribution (jasait); and Population (populationit) as control variables. Some control variables show significant results in the heterogeneity effect. The results obtained show that the interaction of rail network connectivity with government investment and the contribution of the service sector is negative, the contribution of the industrial sector and population is positive.

A major question in the urban planning areas is to understand how urban areas expand. The development of transportation infrastructure such as high-speed railway system is likely to have considerable impacts on the urban growth especially to those area that have access to it. Understanding how the de-elopement will impact the urban growth will be a huge advantage in formulating the spatial plan and to tackle the potential problem. This research attempt to understand how the urban areas expand and analyse the expansion and its relationship with the development of high-speed railway systems by using Artificial Neural-Network Cellular Automata (ANN-CA) approach, utilizing the Modules for Land Use Change (MOLUSCE) plugin in QGIS. This approach has resulted in assisting us to understand the urban expansion pattern and analyse the important component that link the expansion with the infrastructure: Accessibility. By implementing the CA approach, this research also demonstrate that the ANN-CA approach is a promising approach for researcher to understand and analyse the spatial areas in the way it is intended: in spatial manner.

As leading higher education institutions, top universities generate significant daily traffic. In addition, its high education quality often attracts youth to migrate and live closer to the university complex. The development of novel policies that support sustainable transport mode usage will become a role model and provide public benefits to the environment. Yet, there is little knowledge and limited research on university student mobility. This study aims to identify the significance of the daily trip distribution generated by top university students and identify the sustainability of its transportation modes by taking Bandung, Indonesia, as a case study. Responses from 383 students at 4 top universities were collected and then analysed using comparative analysis. The analysis reveals that 66,48 % of the students live in an area less than a 5 Km radius, yet, still depend on non-sustainable transport modes. This finding carries important policy implications to encourage more sustainable transport mode usage within this 5 Km area.
