Abstract

Sabun cair digunakan sebagai pembersih dengan media air. Bahan yang ditambahkan pada sabun cair seperti pewangi, pelembab, antiseptik, penambah busa dan lain lain. Antiseptik merupakan zat yang bisa membasmi atau menghambat pertumbuhan kuman seperti virus, bakteri atau jamur. Bahan antiseptik dapat berupa bahan kimia atau bisa juga bahan alami yang mengandung zat antiseptik seperti lidah buaya, daun sirih, eco-enzym dan lain lain. Eco-enzyme mempunyai arti enzim ramah lingkungan mengandung asam asetat, dan berbagai enzym seperti lipase, tripsin, amilase yang mampu membunuh bakteri patogen sehingga dapat digunakan sebagai bahan antiseptik pada sabun. Kegiatan Pengabdian pada masyarakat berupa penyuluhan dan praktek pembuatan sabun cair dilaksanakan di desa Burai Tanjung Batu, Ogan Ilir. Peserta umumnya ibu ibu dan remaja putri yang berjumlah sekitar 20-30 orang. Metode pembuatan sabun cair dengan eco-enzym sangat mudah dipahami oelh peserta dan memberikan peluang membuka usaha pembuatan sabun cair antiseptik.

Abstract

The limitations of CuO photocatalyst include high electron–hole recombination and low charge-transfer efficiency. In this context, doping with Fe3O4 is used to form a heterojunction, which enhances charge separation, increases electron transfer, and imparts magnetic properties for easy separation and reuse of the catalyst. Therefore, this study aimed to synthesize a biphasic CuO/Fe₃O₄ composite using Rhodomyrtus tomentosa leaf extract as a green reducing agent, and evaluate the performance as a photocatalyst for the degradation of Crystal Violet Dye (CVD). Structural, morphological, optical, and magnetic properties were characterized using X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), UV–Vis diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometer (VSM). XRD patterns confirmed the coexistence of CuO and Fe₃O₄ phases, indicating successful composite formation. VSM analysis reported that the composite had magnetic properties with a saturation magnetization and band gap values of 46.92 emu/g and 1.63 eV, respectively. Process optimization was conducted using Response Surface Methodology (RSM) based on Central Composite Design (CCD). The results showed that the quadratic model was the most appropriate and statistically significant model, indicated by a p-value < 0.05 with a coefficient of determination (R2) of 0.9953. In addition, optimization of the degradation process led to CVD degradation efficiency of 98.73% under optimal conditions of initial concentration of 25.4 mg/L, pH 9.5, and irradiation time of 39.4 min with a visible-light radiation source. The composite also reported good reusability, retaining 92.11% of degradation efficiency after five cycles, confirming the potential as a magnetically recoverable, environmentally sustainable photocatalyst for wastewater treatment applications.

Abstract

Pengabdian kepada masyarakat dengan tema edukasi dan pemanfaatan bahan alam untuk pembuatan eco print dilaksanakan di Desa Tanjung Seteko, Kecamatan Indralaya, Kabupaten Ogan Ilir. Kegiatan ini bertujuan meningkatkan pengetahuan dan keterampilan masyarakat dalam memanfaatkan tanaman lokal sebagai bahan pembuatan eco print. Metode kegiatan meliputi penyuluhan, demonstrasi, praktik langsung, serta evaluasi melalui pre-test dan post-test. Kegiatan dilaksanakan pada bulan Oktober 2025 dan diikuti oleh 25 peserta yang terdiri dari ibu rumah tangga dan remaja putri. Materi disampaikan melalui ceramah, diskusi, serta demonstrasi dan praktik pembuatan eco print menggunakan daun dan bunga dari tanaman yang tumbuh di sekitar desa. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan peserta, yang ditunjukkan dari nilai rata-rata pre-test sebesar 46 menjadi 70 pada post-test. Hasil ini menunjukkan bahwa kegiatan penyuluhan dan pelatihan mampu meningkatkan pemahaman peserta mengenai konsep, bahan, dan teknik pembuatan eco print. Kegiatan ini juga meningkatkan wawasan dan keterampilan peserta dalam memanfaatkan tanaman lokal menjadi produk eco print yang bernilai estetika dan berpotensi memiliki nilai ekonomi serta dapat dikembangkan sebagai peluang usaha kreatif yang ramah lingkungan Kata Kunci : eco print; bahan alam; Desa Tanjung Seteko; teknik pounding; edukasi

Abstract

Ecoenzyme is a product of facultative aerobic fermentation for 3 months from organic fruit and vegetable waste. In this study, ecoenzyme was made from a mixture of fruit peel waste (papaya, orange and pineapple) with the addition of 6 liters of water. Ecoenzyme products were characterized by organoleptic properties, chemical composition, enzyme activity and antibacterial activity tests against Lactobacillus acidophilus and Streptococcus mutans bacteria that cause dental caries. The results of the study show that the ecoenzyme product had a dominant orange peel sour flavor, was cloudy brown in color with a volume of 8.4 liters from 6 liters of added water. The characterization results depict that the chemical composition of ecoenzyme contained acetic acid and lactic acid with a total acid content of 2.26%, 40.45 mg/mL protein, and secondary metabolites in the form of alkaloids, flavonoids, and saponins. The activity of several enzymes from ecoenzyme was protease 0.0246 U/mL, amylase 0.0032 U/mL and lipase 5 U/mL. Antibacterial activity against bacteria that cause dental caries is included in the category of very strong against S. mutans at a concentration of 40 (% v/v) and moderate against L. acidophilus with inhibition zone diameters of 23.33 mm and 8.23 mm respectively. The Mininum Inhibitory Concentration (MIC) and Minimum Killing Concentration (MKC) values of ecoenzyme against S. mutans and L. acidophilus bacteria were 2500 ppm and 5000 ppm respectively.Keywords: ecoenzyme, fruit-peel waste, L.acidophilus, S.mutans, antibacterial
