Abstract

Mikroplastik diartikan sebagai plastik yang berukuran kurang dari 5 mm. Mikroplastik telah terdeteksi secara luas di lingkungan perairan dan menjadi kontaminan yang sangat mengkhawatirkan. Oleh karena itu sangat diperlukan cara untuk menghilangkan mikroplastik dari air secara efektif. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh penambahan surfaktan asam oleat (OA) dan polietilen glikol (PEG) pada nanopartikel magnetit untuk pemisahan mikroplastik polyethylene terephthalate (PET) di media air. Penambahan surfaktan memungkinkan nanopartikel dapat terdispersi dengan baik dan lebih stabil. Nanopartikel magnetit disintesis dari pasir besi pantai Watu Ulo Jember dengan metode co-precipitation. Nanopartikel magnetit dikarakterisasi menggunakan PSA untuk mengetahui distribusi ukuran partikel dan FTIR untuk menentukan gugus fungsi pada n-Fe3O4 yang telah dimodifikasi dengan OA dan PEG. Ukuran partikel yang didapatkan berkisar antara 458,7–955,4 nm dengan intensitas tertinggi 712,4 nm. Efisiensi adsorpsi mikroplastik yang diperoleh menggunakan n-Fe3O4 adalah 77,8%, n-Fe3O4/PEG 91,7%, dan n- Fe3O4/OA 95,2%.

Abstract

Vegetable waste is often discarded without further processing, which can lead to environmental pollution. In fact, this waste still contains 12.64%–23.5% crude protein and 20.76%–29.18% crude fiber, which can be repurposed into an environmentally friendly, value-added product: fish pellets. The lack of understanding regarding this waste poses a challenge, necessitating alternative solutions. This outreach method serves as an educational solution to enhance understanding of the potential of vegetable waste as a raw material for fish pellets. The outreach activity was conducted at SMK Muhammadiyah 7 Gondanglegi and was attended by students from various departments. The implementation stages included preparation, outreach, and evaluation. During this activity, participants were provided with materials on the benefits of vegetable waste and the steps for processing it into fish pellets. A question-and-answer session followed this to allow participants to explore the material in greater depth. The results of this activity have tangibly improved participants' understanding of processing vegetable waste into fish pellets. Participants played an active role and participated enthusiastically in this activity, creating a positive impact on both the participants and the school. Consequently, this activity can be further developed with the school's support to ensure the program's sustainability.

Abstract

This study investigated the optimization of biodiesel production from nyamplung (Calophyllum inophyllum) oil using a Thermal Air Sparging (TAS) reactor with NaOH catalyst. Crude oil containing 18.2% free fatty acids (FFA) underwent a two-stage acid esterification to reduce the acidity below the 2% threshold required for efficient alkaline transesterification. To assess the combined effects of thermal and hydrodynamic variables, a 3² full factorial experimental design with three replications was used, encompassing a reaction temperature of 30–40 °C and a hot air flow rate of 1.0–2.0 L min⁻¹. The produced biodiesel was characterized for density, kinematic viscosity, flash point, and heating value according to ASTM D4052, D445, D93, and D240, respectively. These values ​​were then evaluated against SNI 7182:2015 specifications. Optimal operating conditions were achieved at 35°C and a flow rate of 1.5 L min⁻¹. Reaction temperature emerged as the primary factor influencing biodiesel conversion, while hot air flow rate predominantly affected interfacial contact and residence time. Under these conditions, the biodiesel exhibited a density of 0.867 g·cm⁻³, a kinematic viscosity of 4.67 cSt, a flash point of 183.2°C, a calorific value of 10,283.20 cal·g⁻¹, and a conversion yield of 85.43%. This performance is attributed to the combined effects of heat transfer and dispersion driven by microbubbles, which continuously renew the interfacial surface area between the reactants and promote a more homogeneous reaction environment at atmospheric pressure and relatively low temperature. In contrast to mechanical stirring systems and other high-energy intensification methods, the TAS configuration allows for intensification of the thermofluidic process, reducing reaction time, stabilizing fuel properties, and lowering overall energy consumption. These results demonstrate the potential of TAS as a practical and scalable method for converting non-edible oils with high free fatty acid content into biodiesel through a low-energy process.

Penelitian ini bertujuan mengekstraksi flavonoid serta menganalisis nilai Sun Protection Factor (SPF) U. lactuca menggunakan kombinasi metode cell disruption dan ultrasound-assisted hot water (UAHW). Tiga metode perlakuan cell disruption (tanpa perlakuan, osmotic shock, dan hidrotermal dengan autoklaf) dikombinasikan dengan variabel UAHW yaitu suhu ultrasonik (40, 60, 80 °C) dan waktu ultrasonik (5, 10, 15 menit). Ekstraksi dilakukan menggunakan pelarut etanol 96% pada serbuk U. lactuca berukuran 60 mesh. Optimasi dilakukan menggunakan Response Surface Methodology (RSM) dengan Box–Behnken Design (BBD). Hasil menunjukkan bahwa total flavonoid dan nilai SPF tertinggi (33,23 mg QE/g dan SPF 20,80) diperoleh tanpa perlakuan cell disruption, pada suhu 80 °C dan waktu ekstraksi 10 menit. Penelitian ini menegaskan bahwa metode UAHW efektif meningkatkan ekstraksi flavonoid dan SPF meskipun tanpa cell disruption. Selain itu, pendekatan RSM terbukti efisien dalam optimasi proses. Studi ini memberikan kontribusi pada pengembangan bahan aktif alami U. lactuca untuk aplikasi kosmetik, khususnya sebagai agen pelindung sinar UV.Optimization of Flavonoid Extraction from Ulva lactuca Using a Combination of Cell Disruption and Ultrasound-Assisted Hot Water. Ulva lactuca is a marine organism with significant potential as a source of active ingredients for cosmetic applications, owing to bioactive compounds such as flavonoids, alkaloids, saponins, terpenoids, and tannins. This study aimed to extract flavonoids and evaluate the Sun Protection Factor (SPF) of U. lactuca using a combination of cell disruption methods and ultrasound-assisted hot water (UAHW) extraction. Three cell disruption treatments (no treatment, osmotic shock, and hydrothermal using an autoclave) were combined with UAHW variables, including ultrasonic temperature (40, 60, 80 °C) and ultrasonic time (5, 10, 15 minutes). The extraction was conducted using 96% ethanol as a solvent on U. lactuca powder sieved to 60 mesh. Optimization was performed using Response Surface Methodology (RSM) with a Box–Behnken Design (BBD). The highest total flavonoid content (33.23 mg QE/g extract) and SPF value (20.80) were obtained without cell disruption, at 80°C for 10 minutes. The study confirms that UAHW effectively enhances flavonoid extraction and SPF, even without cell disruption. Furthermore, the RSM approach proved efficient for process optimization. This study contributes to developing natural active ingredients from U. lactuca for cosmetic applications, particularly as UV-protective agents.

Abstract

Indonesia has been recognized for its rich natural ingredients such as spices,herbs, and extracts for decades. Furthermore, these components also have been used as an herbal medicine for a long time. Meanwhile, the apparent capability comparison of several components of antimicrobial activity has not been updated yet. This study was conducting the comparison of antimicrobial activity for several materials such as noni (Morinda citrifolia), garlic (Allium sativum), celery (Apium graveolens), galangal (Alpinia galangal), ginger (Zingiber officinale), yellow turmeric (Curcuma longa), lime (Citrus aurantifolia), papaya (Carica papaya) leaf, betel (Piper betel) leaf, and cutcherry (Kaempferia galangal) using agar dilution method. Two types of bacteria are used for the test, namely gram-negative bacteria and gram-positive bacteria, with a total of seven bacteria. The media used were TSA (Trypticase Soy Agar) media for gram-negative bacteria and MRSA (Methicillin-Resistant Staphylococcus Aureus) media for gram-positive bacteria. This study had been conducted by using a fast screening method, which is referred to as a semi-qualitative method. Several components, such as noni, lime, and betel leaf, showed a significant result of antimicrobial activity. Otherwise, other compounds, surprisingly, could not suppress bacterial growth.
