Abstract

Quality learning will produce quality graduates, namely those who meet 21st century skills, namely critical, creative, innovative thinking and analytical skills so that they can solve problems in everyday life. Students at SMAN 1 Sindue do not yet have an interest in conducting research. The purpose of community activity is to increase students' insight and attract students' interest in conducting research by utilizing materials from superior regional plants. The method used: socialization and demonstration to students of the Science Department, grades X and XI, SMAN 1 Sindue. Socialization begins by explaining the framework for conducting research, starting with finding the background of a study being conducted. Continued by providing material on literature reviews and research methods. The community service team demonstrated the Pb2+ ion absorption process assisted by students. Furthermore, an explanation was given on how to analyze the data obtained. Overall, this activity has opened students' insights in seeing problems in the environment so that they can be poured into a research proposal.

Abstract

Kualitas cahaya merupakan salah satu faktor yang berperan penting dalam produksi microgreen di lingkungan terkendali. Lampu LED banyak dimanfaatkan karena menghasilkan spektrum cahaya yang dapat diatur sesuai kebutuhan tanaman dengan efisiensi energi tinggi dan emisi panas yang rendah. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan spektrum cahaya antara lampu LED putih dan lampu LED multispektrum terhadap pertumbuhan, kandungan polifenol, dan aktivitas antioksidan microgreen brokoli. Penelitian ini menggunakan Rancangan Acak Lengkap dengan perlakuan perbedaan spektrum cahaya LED yaitu LED putih dan LED multispektrum pada budidaya microgreen brokoli. Parameter yang diamati meliputi tinggi dan bobot segar tanaman, kandungan polifenol, dan aktivitas antioksidan. Data dianalisis menggunakan uji t pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa jenis lampu LED tidak berpengaruh nyata terhadap tinggi tanaman dan bobot segar microgreen brokoli. Sebaliknya, penggunaan lampu LED multispektrum menghasilkan kandungan polifenol yang lebih tinggi dan aktivitas antioksidan yang lebih kuat, sebagaimana yang ditunjukkan oleh nilai IC50 yang lebih rendah. Kandungan polifenol juga menunjukkan korelasi positif yang kuat dengan aktivitas antioksidan. Hasil penelitian ini mendukung penggunaan lampu LED multispektrum dalam budidaya microgreen brokoli di lingkungan terkendali untuk menghasilkan produk dengan kualitas fungsional yang lebih baik. Temuan ini dapat dimanfaatkan sebagai dasar dalam pengembangan sistem produksi microgreeen berkualitas tinggi, khsusunya untuk memenuhi kebutuhan pangan fungsional yang kaya senyawa bioaktif dan memiliki aktivitas antioksidan tinggi. Light quality is one of the key factors influencing microgreen production in controlled environments. LED lamps are widely used because they generate a light spectrum that can be adjusted according to plant needs, with high energy efficiency and low heat emission. This study aims to determine the effect of different light spectra between white LED and multispectral LED on the growth, polyphenol content, and antioxidant activity of broccoli microgreens. The study employed a Completely Randomised Design with treatments consisting of different LED light spectra, namely white LED and multispectral LED, in broccoli microgreen cultivation. Observed parameters included plant height and fresh weight, polyphenol content, and antioxidant activity. Data were analysed using a t-test at 5% significance level. The results showed that the type of LED light had no significant effect on the plant height or fresh weight of broccoli microgreen. Conversely, the use of multispectral LED lights yielded higher polyphenol content and stronger antioxidant activity, as evidenced by the lower IC50 values. Polyphenol content also shows a strong positive correlation with antioxidant activity. The results of this study support the use of multispectral LED light for cultivating broccoli microgreens in controlled environments to produce product with improved functional quality. These findings can serve as a basis for developing high quality microgreen production systems, particularly to meet the demand for functional foods rich in bioactive compounds and high in antioxidant activity.

Abstract

Azolla pinnata and Azolla filiculoides can be used as heavy metal phytoremediators, but A. pinnata is not a hyperaccumulator. Plant response to heavy metals is not only seen from the ability to accumulate heavy metals, but also from the aspects of growth and changes in plant tissue structure. This study aimed to evaluate the development, leaf anatomy, and ability to absorb mercury in Azolla with non-hyperaccumulator and hyperaccumulator characters. The study was conducted by growing A. pinnata and A. filiculoides in containers containing 5 L of hydroponic solution that was either mercury-free or polluted with mercury at a concentration of 0.5 ppm. The results showed that A. filiculoides showed better tolerance and physiological adaptation to mercury contamination compared to A. pinnata, which experienced a decrease in biomass due to low detoxification ability. The detoxification ability of A. filiculoides is also supported by the anatomical adaptation in the form of leaf mesophyll thickening. Although A. pinnata absorbed more mercury, its inability to overcome toxic effects reflected different adaptation strategies. The ability of A. filiculoides to store mercury without disturbing its physiology shows its potential as a promising phytoremediation agent.
