This study aims to help the residential community of Valencia, Muaro Jambi to get clean water using filter multi media-sabut pinang (FMM-SP).Multimedia filtration is a method of water treatment by utilizing soil as the main medium which is shaped like brick blocks and arranged alternately between zeolites.The LMM-FSP reactor is made of used gallons, 40 cm high, 28 cm in diameter, containing brick blocks (12x7x4) cm consisting of a mixture of volcanic soil, charcoal, areca fiber, iron powder (70 :10 :10: 5) %, permeable layer used zeolite (1-3 mm). The samples came from the wells of residents of Valencian housing, Muaro Jambi, Jambi City. The research was carried out with variations in the mass of areca nut into the filter, flow rates of 5, 10, 15, 20 mL/minute and two ways, namely aeration and non-aeration. FMM-SP efficiency for the aeration process at a flow rate of 5 ml/min with pH parameters; Smell; Nitrite; Nitrate; turbidity; Mn; Fe in order is 7.5; Odorless, 60.30%; 59.33%; 59.33%; 70.10%; 73.20%, and in non-aerated pH 7.3; Odorless; 50.82%; 48.37%; 60.91%, Fe 61.20% From all the efficiency values for decreasing the parameters, it can be said that it meets the requirements for clean water.

This study aims to determine the efficacy of using smartphones as portable mini-labs to improve students' beliefs about physics. This study takes a hybrid approach, using an exploratory mixed-method research design. The qualitative step entails creating teaching resources as a laboratory manual focusing on momentum and impulse. Simultaneously, the quantitative phase evaluates the usefulness of using smartphones as mobile mini laboratories to improve students' beliefs about physics and the process of learning physics using a quasi-experimental, non-equivalent control group design. According to the research findings, the laboratory manual developed during the qualitative stage has been declared valid and appropriate for learning by expert validators and teacher practitioners. Furthermore, using smartphones as portable tiny laboratories in physics teaching significantly improves students' beliefs about physics, notably the dimension of real-world connection, which has grown significantly. This research will have favourable implications for enhancing beliefs and proficiency in physics topics and cultivating students' interpersonal and communication abilities. Laboratory activities are crucial since they provide students the chance to partake in diverse genuine scientific procedures, including the design and execution of experiments, the gathering and analysis of data, and the dissemination of scientific knowledge.

Nanotechnology is a fast expanding field with several applications in science, engineering, healthcare, pharmaceutical, and other areas. Nanoparticles (NP) are frequently produced through a variety of physical and chemical methods. Recently, green synthesis technologies that are more simple, sustainable, and cost-effective have been developed. The environmentally friendly/sustainable synthesis of titanium dioxide nanoparticles (TiO2 NPs) has been in great demand in the previous quarter. Bioactive components found in organisms, such as plants, facilitate the processes of bio-reduction and restriction. This review described green synthesis of TiO2 NPs, the photocatalytical uses, and managing the larvicidal activity of disease-spreading mosquitoes. Various natural reducing agents including proteins, enzymes, phytochemicals, and others, are involved in the synthesis of TiO2 NPs. Current research findings and future concerns in a viable platform based on biologically meditated TiO2 nanostructures for industrial applications.

The textile industry is a major contributor to pollution, with 10-15% of dyes lost in wastewater during processing, including Methyl Violet. The degradation products of these dyes are often carcinogenic. Conventional biological treatment methods are ineffective due to the complex nature of synthetic dyes. A study aimed to develop a new photocatalytic activity using a UV A lamp and sonolysis using a sonicator. The study modified TiO2/Activated Carbon from Rice Husk as a catalyst to degrade Methyl Violet and textile industry effluent effectively, which was dual benefits as an adsorbent-photocatalyst. Results showed that the degradation by sonolysis and photolysis was 12.99% and 79.16%, respectively. The degradation by photolysis was 14.95% and 94.12%. The light and catalyst with the highest percentage of degradation were TiO2/activated carbon with UV A light of 94.12%. This study aims to develop effective treatment techniques for the textile industry's dyes.

The halal food study is one of the prominent research fields in halal trends. Currently, the halal food concept is not only the worship of Muslims to Allah, but also this concept is adopted by non-Muslim with healthy lifestyle considerations. Therefore, the insight of the influenced variable on purchased intention behavior of students is crucial to research as basic information for all stakeholders, such as the seller, marketer, policymaker, government, and researchers. This study aims to identify and compare the independent variables that influence the behavior of students' purchase intentions from the school's clustering perspective. A quantitative approach has investigated the influence of attitude and need for cognition (NFC) variables on students' purchase intention behavior on halal food. The self-administrated questionnaire was used to collect the data from 561 respondents and input them into the Survey123 software. The data were analyzed using descriptive and interferential statistics. The result showed that attitude toward halal (HA) and NFC were accepted as the influenced variable on halal food purchase intention behavior. Furthermore, the students from Islamic schools tend to have purchase intentions on halal than in senior high The result of this study could be strategic marketing in the halal food industry. Then, the school must strengthen halal awareness in the syllabus.

Purpose of the study: This study investigates the relationship between students’ attitudes and their motivation to study physics in vocational high schools. Recognizing that physics is often perceived as a difficult subject, this research seeks to understand how affective factors influence student engagement and achievement, particularly in vocational education settings where applied sciences are critical. Methodology: The study employs a quantitative descriptive design with a correlational approach, using validated questionnaires distributed to vocational students. To enrich the quantitative findings, semi-structured interviews were conducted to explore students' perceptions more deeply based on specific indicators of attitude and motivation. Data were analyzed using both descriptive and inferential statistics, particularly Pearson correlation analysis. Main Findings: The results revealed that both students’ attitudes towards physics and their motivation to learn were generally in the “fairly good” category. A positive and significant correlation between the two variables was found, with a moderate Pearson correlation coefficient of 0.622, indicating that students with a more positive attitude tend to have higher motivation levels. This emphasizes the vital role of affective domains in supporting physics learning outcomes. Novelty/Originality of this study: This study introduces a novel integrated analytical framework that merges quantitative correlation data with qualitative insights, providing a deeper understanding of the synergy between attitudes and motivation. Unlike previous research that often examined these factors independently, this study emphasizes their interrelated impact on vocational physics education, offering new directions for designing affective-based learning interventions aimed at improving student cognitive, affective, and psychomotor performance in technical fields.

There are differences in the mosques performed before and during the Covid-19 pandemic, but these differences do not hinder the mosque's goals. This study aims to find out how the role of mosques in fostering reading the Qur'an during the Covid-19 pandemic and the inhibiting and supporting factors. Research on the involvement of mosques in the development of reading the Koran during the pandemic has been explored using a qualitative case study approach. The data collected was obtained using field research methods and literature studies. The findings in this study explain that the power of mosques as educational centers continues during the Covid-19 pandemic. The spirit of reading the Koran during the pandemic encountered several obstacles. This study provides distribution in theory and practice for Muslims during the Covid-19 pandemic for empowering mosques as an educational center.
