Abstract

 Bangka Belitung Islands Province faces severe environmental challenges, exacerbated byillegal tin mining activities leading to heightened pollution levels, particularly in stagnantwater within former tin mining holes, reaching depths of up to 40 meters. The presence ofiron metal (Fe) in this water poses a health risk, potentially damaging intestinal walls andcompromising lung function upon ingestion. This study presents a novel approach to addressthis issue by synthesizing porous carbon material from propylene waste sourced frommedical masks. The process involves initial sulfonation for sterilization and pore sizeenhancement, followed by activation using KOH and carbonization at 750 °C.Characterization methods validate the successful synthesis, including FTIR highlightingpolypropylene groups at 822 cm-1, XRD indicating graphite carbon with high crystallinity,and SEM exhibiting rod shapes and cavities at 5,000í— magnification. The adsorption testdemonstrates outstanding performance, with porous carbon exhibiting a 100% adsorptionefficiency in purifying water, eliminating odors, and reducing iron (Fe) levels. Thisinnovative method effectively reduces iron levels in stagnant water environments, providinga sustainable solution to environmental pollution, particularly in Bangka Belitung.

Abstract

One indicator of a country's national development is its economic growth. Economic development is an indicator to find out how successful a country's economic development is and also as a determinant of development policies that will be formed next. Economic growth and development aim to increase job opportunities for the community, which must involve all levels of society in its implementation. One component that plays an important role in Indonesia's economic growth is Micro, Small and Medium Enterprises (UMKM) and also Domestic Investment (PMDN). UMKM plays a role in the absorption of labor so that they also contribute to national income. However, the economic growth of a country can also be helped by investment. This research is a normative legal research using secondary data, as well as a statutory approach which is then compiled qualitatively. The conclusion of this study shows that the role of UMKM in the development of investment in Indonesia is in terms of expanding the provision of employment, making a significant contribution to the development of a country, distributing income increases and increasing the competitiveness and resilience of the national economy. Meanwhile, PMDN plays a role in financing which is important for developing regions and is able to make a sizable contribution to development and plays a role in increasing economic growth through a conducive investment climate in Indonesia.

Abstract

The primary objective of this study is to investigate the impact and variations associated with the utilisation of the make a match strategy on the reading comprehension abilities of pupils. The present work employs a quantitative approach and adopts a quasi-experimental methodology. The research was carried out using two distinct groups, specifically the experimental group and the control group. The participants in this study consisted of students from class VIII A and VIII B of SMP Negeri 20 Kabupaten Tebo. The participants in this study consisted of a total of 34 students, with 17 students assigned to the experimental class and another 17 students assigned to the control class. The average findings obtained from both courses were subjected to statistical analysis using a T-test, with a significance level of α = 0.05. This phenomenon is observable in both the paired sample T-test and the independent sample T-test. The findings indicate that the mean reading comprehension score of students who received instruction using the make a match technique was 1.175. This result aligns with the hypothesis criteria, which states that a score below 5% would be considered low. A significance level of 0.05 indicates that the alternative hypothesis (Ha) is accepted. Therefore, it can be inferred that the implementation of the make a match strategy has a notable impact on the development of students' learning abilities. In the interim, the outcomes of the independent sample t-test indicated a mean difference of 4.824 and a two-tailed significance level of 0.05 (1.175 ≤ 0.05). Based on the aforementioned description, the null hypothesis (Ho) is rejected, whereas the alternative hypothesis (Ha) is accepted. This indicates a notable disparity in the application of the make a match strategy between the experimental group and the control group in relation to the enhancement of students' reading proficiency at SMP Negeri 20 Kabupaten Tebo.

Abstract

In an era of globalization, digitalization, and rapid organizational change, transformational leadership has emerged as an increasingly relevant and necessary leadership model. Transformational leadership emphasizes core values such as idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. These values directly contribute to the development of a dynamic, adaptive, and innovative organizational culture. Transformational leaders do not merely direct; they inspire and guide team members to exceed their performance limits through a compelling vision and ethical role modeling. This article explores in depth how transformational leadership values serve as key elements in enhancing productivity, employee loyalty, sustainable innovation, and in building trust and integrity within modern organizations. In an increasingly complex and multicultural work environment, transformational leaders are capable of aligning individual goals with the organization’s vision. Through a human-centered approach, they act as catalysts for change and reformers in contemporary organizational management. Therefore, the application of transformational leadership values is not only important but has become a strategic necessity for the sustainability and competitiveness of today’s organizations.

Abstract

This study aims to determine the cost of production using the full costing method, compare it with MSME calculations, and set the selling price using the cost plus pricing method. This research was conducted at MSME Doyan Donat in Sambas, which has not implemented a comprehensive cost recording system. The results showed a difference of IDR 23,943,880 between MSMEs’ conventional calculation and the full costing method. Setting the selling price using the cost plus pricing method resulted in a price of IDR 2,308 per donut, while the MSME’s version was only IDR 1,192. This discrepancy of IDR 1,116 emphasizes the importance of applying cost accounting methods in strategic decision-making. This study concludes that the full costing and cost plus pricing methods significantly contribute to helping MSMEs set rational and profitable selling prices.

Abstract

Education in Indonesia, including at SMP 05 Sutera Pesisir Selatan, has summarized the curriculum applied at all levels of education, including the 2013 Curriculum. Each lesson aims to develop students' cognitive, affective and psychomotor aspects. Affective, cognitive and psychomotor assessments are carried out through observation and analysis of the learning process, especially in learning persuasive speech texts. However, there are obstacles in the learning process, including students' difficulties in writing speech texts and the lack of variety and flexibility in the teaching methods used by teachers. The learning process only involves assessments at the beginning and end of learning, while the lack of variety and flexibility in teaching methods can hinder student creativity and independence. This research aims to analyze the process of learning persuasive speech texts at SMP 05 Sutera Pesisir Selatan using the 4C approach (Critical Thinking, Creative Communication, and Collaboration). Qualitative research methods were used with research instruments in the form of observation, interviews and documentation. The research results show that learning planning includes providing learning tools and the necessary hardware and software. The learning process consists of three stages: opening, core, and closing, which involve activities such as attendance, introduction to material, and group discussions. Evaluation of the learning process involves authentic assessment in the cognitive, affective and psychomotor domains, with assessment techniques such as written tests, observations and assignments.

Abstract

Sungai Tallo adalah salah satu Sungai yang sangat penting perannya bagi masyarakat kota Makassar sebagai jalur transportasi maupun dalam bidang perikanan. Kondisi air sungai Tallo yang sering meluap dari sungai karena debitnya bertambah dengan cepat sehingga melebihi daya tampung sungai, air hujan yang jatuh di permukaan mengikis tanah sehingga terbawa oleh aliran air ke dalam sungai. Kondisi inilah yang menghasilkan dampak dari proses sedimentasi. Penelitian ini bertujuan untuk mengetahui angkutan sedimen didasar sungai Tallo, sehingga dapat diperkirakan laju sedimentasi yang terjadi. Penelitian dilaksanakan selama dua bulan yaitu pada bulan April dan Mei 2023 dengan tujuan untuk mengetahui laju sedimentasi yang terjadi selama dua bulan dengan menggunakan metode Duboys dan Mayer Peter. Hasil penelitian menunjukkan angkutan sedimen menggunakan metode Duboys pada bulan April diperoleh sebesar 3,0651 m3/hari, dan pada bulan Mei diperoleh sebesar 1,8752 m3/hari. Untuk metode Mayer Peter pada bulan April diperoleh sebesar 3,2154m3/hari dan pada bulan Mei diperoleh sebesar 2,0570 m3/hari.
