Various efforts can be made to obtain clean water in the environment by utilizing semiconductor technology. This study aims to inform the synthesis and characterization of MnO2/CuO/Fe2O3 photocatalyst for crystal violet degradation in wastewater. Nanocomposite was synthesized through a sol-gel process with three semiconductor materials doped. X-ray diffraction (XRD) was employed to analyze the nanocomposite structure and determine crystal size. Fourier transform infrared (FTIR) was used to provide functional groups in the nanocomposite. A scanning electron microscope (SEM) can characterize surface morphology and particle size. The results of the SEM show that an increase in sintering temperature causes the smallest particle sizes to be 54.79 nm. The result of characterization using the ultraviolet-visible (Uv-Vis) spectrophotometry analysis the most effective band gap value in photocatalyst activity was 1.36 eV. The optimum percent of degradation MnO2/CuO/Fe2O3 catalyst was 50.40% for .....

This wireless monitoring system is developed to alert and warn the resident regarding the upcoming flood. Due to the floods that occur every year, especially during the monsoon season, the loss and damage done by this disaster are uncontrollable. When the water level rise-up above the safe ground, it may hit the communication substation, as well as the power tower. In most cases, many residents are not alert with their surroundings because there is no alert system that can remind them regarding to the issues that will arise. By not preparing themselves for the upcoming nature disaster, it could endanger themselves and destroy their property. Thus, this project focus on monitoring a real-time river water level system for flood prediction purposes which utilize three devices connected together in a centralized system. By having this system, people will be notified about the current situation and the water level of the river near to them via Internet of Things (IoT) such as Blynk applicat.....

Green development is an effective mode of economic growth and social development aiming at efficiency, harmony, and sustainability, which has become an important trend. The development of green industry is taken by many countries as an important measure to promote economic restructuring and highlighting environmental awareness. The green chemistry literacy is the inner driving force of developing green industry, which is studied as a focus in this paper. At the same time, the public literacy of ideological and political consciousness (PLOIPC) is closely related to green chemistry literacy. Therefore, the coupling analysis between green chemistry literacy and PLOIPC is presented. In the detail, three-level index evaluation tree models of green chemistry literacy and PLOIPC are set up. Then, the mathematical model is built with the index system of PLOIPC and green chemistry literacy based on the analytic hierarchy process (AHP). The criteria standard value is given to get the weighting c.....

The clustering climbing palm genus Korthalsia Blume (Arecaceae: Calamoideae: Calameae) is widespread in the Malesian region with 28 documented species. However, as many as 18 species are available in Malaysian rainforests. An inquiry was carried out in 2019 throughout Malaysia that included species richness and phytogeographic affinities for Korthalsia. Currently, Korthalsia is highly diverse in Sabah and Sarawak, with 15 species documented in this region, whereas 9 species are present in the Malay Peninsula. Species of Korthalsia were dominated by Korthalsia echinometra Becc., Korthalsia flagellaris Miq., Korthalsia hispida Becc., Korthalsia rigida Blume, and Korthalsia rostrata Blume, which suggests their prevalence in richness compared to being diverse; only 5 species found in all regions. The species accumulation curve indicates that this region's rattan community is moderately rich. There is an east-west separation for the distribution of rattan species in Peninsular Malaysia. Thi.....

The COVID-19 pandemic is a virus that is changing habits in human life worldwide. The COVID-19 outbreaks in Indonesia have forced educational activities such as teaching and learning to be conducted online. Teaching and learning activities using the online method are familiar, but the effectiveness of this method still needs to be investigated to be applied in all educational systems. This study used the predictive modeling of Recurrent Forecasting (RF) derived from Singular Spectrum Analysis (SSA) to know the online learning method's practicality on the student's academic performance. The fundamental notion of the predictive fusion model is to improve the effectiveness of several forms of forecast models in SSA by employing a fusion method of two parameters, a window length (L), and a number of leading components (r). This study used undergraduate students' grade point averages (GPA) from a public university in Indonesia through online classes during the COVID-19 epidemic. The experim.....

Human trafficking, especially involving women, is a planned and transnational crime that spans various countries, including Southeast Asia nations like Malaysia and Indonesia. Trafficking of Indonesian women forced into prostitution in Malaysia is deeply concerning. It requires aggressive and comprehensive government actions to combat the crimes. This preliminary study identifies the root causes of the trafficking of Indonesian women into forced prostitution in Malaysia and the actions taken by the Malaysian government to address this issue. To achieve these objectives, primary data was collected through interviews conducted from May 2023 to August 2023. Four Indonesian women who were victims of trafficking and employed as prostitutes in Malaysia participated in these interviews. Additionally, this study is supported by the report data, including the UNODC Report and the US TIP Report. The study found that the primary factor leading them to become trafficking victims is economic desper.....

Past studies found that teacher self-disclosure positively impacted the socio-psychological aspect of teaching and learning within its dimensions of amount, relevance and negativity. However, much understanding about teacher self-disclosure today is derived from quantitative studies using established scales, conducted in non-Asian countries and usually in high school or college settings. Investigations pertaining to teacher self-disclosure in the English as a Second Language (ESL) classroom and its effects on language learning are limited. Using the qualitative approach, this exploratory study, therefore, aimed to investigate factors essential for understanding teacher selfdisclosure in the Malaysian ESL writing classroom. An ESL teacher was observed in an Academic Writing course that comprised 32 lecture and tutorial contact hours at a private institution of higher learning in Malaysia during a fourteen-week semester. A one-to-one teacher interview was then conducted to supplement the.....

Children currently spend more time on the Internet and corresponding technologies to socialise virtually and play video games. Scholars have not reached a consensus on whether childrens participation in such recreational activities is beneficial or detrimental. Although Malaysian parents are concerned about the digital threats that may be encountered by their children, most of the detriments remain unknown. Children still hesitate to inform their families about their online exposure to inappropriate content, such as cybersex and pornography, which remain taboo subjects in Malaysian households. This study performed a descriptive analysis to determine the risk factors associated with childrens internet use with 420 school-going children aged from 9 to 16 years around Selangor. Resultantly, children were highly exposed to unwanted exposure to pornography (17.4 %), potentially dangerous user-generated content (9 %), sexting (8.8 %), personal data misuse (6.4 %), cyber grooming (3.3 %), and.....

The deprivation of knowledge from the bond of true belief will destroy and ruin human life and nature. This has been demonstrated in the Western scientific and technological civilisations that dominate the world today. Western scientific civilisation today is the product of scientists who have no real faith in the Creator of the universe. Nevertheless, there are efforts among Western scientists who have awareness in this modern era, who began to take steps to restore the agenda of Science and Technology within the framework of religious beliefs. This literature-based study discovers many negative effects resulting from the absence of true theology in understanding Science and Technology, which is based on a secular understanding. Apart from that, this article also reveals the nature and appearance of Science and Technology that are firmly embroidered with natural theology leading to universal well-being. IIUM Press...

Of the many uses of social media, educationists advocate its use for teaching the English language. The traditional method of learning the English language is associated with inattention among learners. The adoption of social media in teaching the English language can create a fun, stress-free, and pleasant environment that is able to cultivate a positive attitude among the learners. Hence, this study carried out a systematic review to assess the use of social media for English learning in the Southeast Asia context. The study systematically searched the peer-reviewed literature using the SCOPUS database and identifi ed 46 articles. After thorough reading, 21 articles met the inclusion criteria. Articles that were excluded from the analysis were conducted outside Southeast Asia, do not focus on Southeast Asias English learning, and do not engage with social media usage. The fi ndings suggest that the use of social media for English learning was associated with improving communication s.....
