Abstract

Ensis sp. is a primary source of protein from the Nyumbun Tradition in Jambi Province, and it is becoming solid waste after tradition. This study explored the effect of calcination temperature on green powder derived from Ensis sp. shell waste. Before characterization, the powder was treated at room temperature, 800 °C, and 900 °C. After that, the powder material was studied using Atomic Absorption Spectroscopy (AAS) and Scanning Electron Microscope (SEM) instruments. The material was shifted using a 200 mesh sieve. Temperature of 800 and 900 °C showed similar Ca content of 443 and 447,6 mg/g, respectively. The morphology of the two samples was different due to the other temperature conditions used. Higher temperatures induce decomposition, leading to a decrease in particle size. The product of this process could be used as a promising heterogeneous catalyst, so it reduced the existence of shell waste. Keywords: shells waste, Ensis sp, heterogeneous catalyst

Abstract

Limbah cair industri batik menjadi permasalahan utama pada lingkungan perairan. Limbah tersebut mengandung kontaminan zat warna yang dapat memperburuk dampak pencemaran lingkungan. Penelitian SLR ini bertujuan untuk mengetahui metode pengolahan zat warna dan jenis zat warna yang digunakan pada industri batik. Penelitian SLR ini menggunakan metode PRISMA 2020 dengan sumber yang berasal  dari Google Schoolar dengan memanfaatkan aplikasi Publish or Perish (PoP). Hasil penelusuran artikel ditemukan sebanyak 22 artikel memenuhi kriteria penelitian. Data penelitian menyatakan bahwa jenis metode yang umum digunakan untuk mengolah limbah zat warna batik adalah adsorpsi karena efisien, ekonomis, dan daya penyerapan yang baik, fleksibel, ramah terhadap lingkungan, dapat diaplikasikan dalam skala besar, dan tetap efektif pada konsentrasi rendah Selanjutnya, zat warna yang sering diteliti yaitu metilen biru. Hal ini disebabkan zat warna ini sangat mudah diserap oleh adsorben, dapat diadsorpsi dengan berbagai material, serta kemampuan MB yang dapat terserap secara merata di seluruh permukaan adaorben. Penelitian SLR ini diharapkan dapat memberikan wawasan akan pentingnya proses adsorpsi sebagai solusi yang ramah lingkungan dalam mengatasi masalah cemaran zat warna pada limbah, terutama di industri batik.

Abstract

Pandan leaves are known as an herbal medicinal plant and are widely used for various diseases. The bioactive compound of pandan leaves has been exhibited to have pharmacological activity as an anti-bacterial. This SLR research aimed to determine the method and type of solvent used to isolate secondary metabolite from pandan leaves. The method used in this research is the PRISMA 2020 using the Publish or Perish application. Articles were obtained from Google Scholar. The evaluation results in this study found that 28 manuscripts fulfil the criteria for isolating natural compounds. Based on the SLR results, it was discovered that the disc diffusion method was frequently employed in this research in ten articles due to its high sensitivity, ease of extraction, and low cost. Meanwhile, ethanol is the most commonly employed solvent in this research because it is inexpensive, low in toxicity, and soluble in water and fat. This study's findings can be utilized to help researchers conduct isolation on natural materials.

Abstract

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.
