Abstract

This community service research introduces a model of digitalizing green fashion through a service-learning approach implemented at Rumah Jahit Nila, a fashion MSME in Medan. The intervention includes intensive training on 3D design software such as CLO 3D and Marvelous Designer, the use of AI-assisted tools like Repsketch for pattern optimization, and production mentoring throughout a 12-month project cycle. Measurements show an increase in students' average technical competency scores from 55.1 to 76.9, representing a gain of 21.8 points. Partner evaluation was conducted through satisfaction questionnaires and field observations, both of which indicated positive acceptance of digital patterns and user guides. Claims regarding waste reduction and material efficiency are currently indicative, as direct quantitative metrics such as percentage reduction in fabric use or paper pattern sheets are not yet available; thus, further measurement is recommended. This study offers a replicable digital technology-based community service model for empowering sustainable fashion MSMEs.

Abstract

Sungai Bedera adalah sungai yang tergolong tercemar logam berat akibat pembuangan limbah rumah tangga dan industri yang memiliki kadar logam berat tembaga (Cu) yang tinggi yaitu 0,6518 mg/L. Cara yang dilakukan untuk menurunkan kadar logam berat tembaga (Cu) adalah dengan memanfaatkan bakteri Indigenous. Penelitian ini bertujuan untuk mengidentifikasi bakteri indigenous dari Sungai Bedera dan menguji kemampuannya dalam menurunkan kadar Cu. Bakteri Indigenous diberi perlakuan dengan nutrisi tambahan yaitu biostimulan glukosa. Metode yang dilakukan yaitu isolasi bakteri indigenous, uji resistensi bakteri dengan menghitung nilai Optical Density (OD) menggunakan spektrofotometer Uv-Vis dan proses penurunan kadar logam berat (Cu) dilakukan dengan metode SSA (Spektrofotometer Serapan Atom). Hasil uji menggunakan One Way ANOVA menunjukkan adanya perbedaan nyata antarperlakuan (Sig. < 0,05). Empat genus bakteri indigenous yang berhasil diidentifikasi memiliki kemampuan menurunkan kadar logam berat tembaga (Cu) yaitu Enterococcus, Bacillus, Corynebacterium, dan Staphylococcus. Persentase penurunan Cu tanpa biostimulan glukosa pada masing-masing bakteri Enterococcus, Bacillus, Corynebacterium dan Staphylococcus adalah 51,49%, 40,65%, 29,39%, dan 20,70%. Persentase penurunan Cu dengan penambahan biostimulan glukosa pada masing-masing bakteri Bacillus, Enterococcus, Staphylococcus dan Corynebacterium adalah (77,60%), (72,28%), (66,66%), dan (60,63%). Bakteri indigenous yang paling tinggi dalam menurunkan kadar tembaga (Cu) dengan penambahan biostimulan glukosa adalah Bacillus dengan persentase penurunan 77,60% dan bakteri indigenous yang paling rendah dalam menurunkan kadar tembaga (Cu) tanpa penambahan biostimulan glukosa adalah Staphylococcus dengan persentase penurunan 20,70%.

Abstract

Deteriorating air quality during seasonal transitions contributes to the increased growth of pathogenic microorganisms, including Aspergillus fumigatus, which may lead to adverse health impacts. Synthetic antifungal agents may induce resistance and undesirable side effects, thereby promoting interest in safer natural alternatives. This study aimed to evaluate the antifungal effectiveness of a nasal spray formulated with kasturi orange (Citrus microcarpa) peel essential oil against A. fumigatus. The essential oil was extracted through steam distillation and tested at five concentrations to identify the most effective range, after which three concentrations exhibiting the strongest antifungal activity were formulated into a nasal spray. Antifungal effectiveness was assessed using the disc diffusion method, morphological alterations of fungal hyphae were observed using Scanning Electron Microscopy (SEM), and statistical analysis was performed using Analysis of Variance (ANOVA). The results showed that the nasal spray demonstrated significant antifungal activity (p < 0.05), with inhibition zone diameters of 12.8 mm, 16.1 mm, and 20.5 mm at essential oil concentrations of 10%, 20%, and 30%, respectively. Although the highest concentration produced the largest inhibition zone, excessively high essential oil levels do not necessarily improve antifungal performance and may trigger adaptive responses approaching resistance. SEM observations confirmed notable cellular damage, including hyphal lysis, cell wall thinning, and structural shrinkage following exposure to the nasal spray formulation. In conclusion, kasturi orange peel essential oil is effective when formulated as a nasal spray to inhibit A. fumigatus, with 20% identified as the most suitable concentration for further product development.
