Abstract

Perkembangan teknologi dan transformasi digital memberikan peluang besar bagi organisasi dan UMKM untuk meningkatkan efisiensi layanan melalui optimalisasi platform digital, seperti website. Penelitian ini bertujuan untuk mengembangkan website OK OCE Indonesia dengan menggunakan framework React JS pada frontend dan Strapi CMS pada backend, yang diintegrasikan untuk meningkatkan efisiensi manajemen konten, kualitas antarmuka pengguna (UI), serta pengalaman pengguna (UX). Penelitian ini menggunakan metode Software Development Life Cycle (SDLC) dengan model Waterfall, yang mencakup tahapan analisis kebutuhan, desain, implementasi, pengujian, dan pemeliharaan. Pada tahap implementasi, React JS digunakan untuk membangun komponen antarmuka yang responsif, sementara Strapi CMS memungkinkan pengelolaan konten secara terstruktur dan efisien. Pengujian dilakukan dalam dua tahap, yaitu alpha testing dan beta testing dengan hasil pengujian menunjukkan bahwa tingkat kepuasan pengguna terhadap fungsionalitas website mencapai 89,5%, tampilan antarmuka 92,16%, dan kemudahan penggunaan 92,16%, yang dikategorikan sebagai “sangat memuaskan”. Hasil penelitian ini menunjukkan bahwa pengembangan website menggunakan React JS dan integrasi Strapi CMS mampu meningkatkan efisiensi manajemen konten dan memberikan pengalaman pengguna yang lebih baik. Implementasi ini diharapkan dapat menjadi referensi bagi organisasi lain dalam mengoptimalkan platform digital mereka.

Abstract

One method to observe biofilms is by inoculating bacteria on glass slides and observed for the presence of large structures (microcolonies) and small structures (clusters, aggregates, or single cells) under a microscope. Analysis of these structures using image processing software may provide a method to quantify biofilm production and degradation in glass slides. In this study, we use ImageJ to quantify the number and area percentage of microbial structures observable on a slide. This study is an experimental in vitro study. Biofilm production was done by submerging slides in petri dishes filled with Brain Heart Infusion with 2% sucrose (w/v) and inoculating it with bacteria. The petri dishes were incubated undisturbed for 48 hours at 37°C (n=3). Afterwards, the slides were removed and submerged in distilled water (Group 1) or detergent (Group 2) for 5 minutes before staining with 0.1% crystal violet and rewashed. The slides were then observed under a light microscope at 1000x and images from five fields of view were collected. ImageJ was then used to count the number of microcolonies (>15.000 μm2), aggregate cells (200 – 14.999 μm2), and single cells or cell clusters (1 – 199 μm2), and their area percentage. Welch’s T-Test was performed using JASP version 0.18.3. Observation of slides shows microcolonies to be formed in Group 1, and no or little in Group 2. Based on ImageJ calculation, slides treated with distilled water had a biofilm consisting of an average 4.60 ± 2.41 microcolony number and an average percentage area of 39.97 ± 9.99%, 120.47 ± 32.31 (8.96 ± 3.19%) cell aggregates, and 415.06 ± 139.85 (1.39 ± 0.33%) single cells and cell clusters. Detergent application possibly showed biofilm breakdown, with a significant (p<0.001) reduction in microcolony percentage area to up to 99% (0.33 ± 0.68% remaining) and increased single cell number and percentage area to 1,754.93 ± 689.52 (5.27 ± 0.49%). ImageJ can be a valuable tool to quantify biofilm production in glass slides based on the number and percentage area of microcolonies, cell aggregates, and single cells or cell clusters.

Abstract

  Background: Direct microscopic observation of biofilms is done by observing for the presence of biofilm under a microscope. However, this method is qualitative and not quantitative. Analysis of these biofilm structures using image processing software may provide a method to quantify biofilm production and degradation in glass slides. Objective: To quantify the number and area percentage of microbial structures observable on a slide. This study is an experimental in vitro study. Methods: Biofilm production was done by submerging slides in petri dishes filled with Brain Heart Infusion with 2% sucrose (w/v) and inoculating it with Staphylococcus aureus. The petri dishes were incubated undisturbed for 48 hours at 37°C (n=3).The slides were then submerged in distilled water (Group 1) or detergent (Group 2) for 5 minutes before staining with 0.1% crystal violet and observed under a light microscope at 1000x. Images from five fields of view were collected. ImageJ was then used to count the number of microcolonies, aggregate cells, and single cells or cell clusters, based on size, and their respective area percentage. Welch’s T-Test was performed using JASP version 0.18.3. Results: Direct observation of slides shows that microcolonies and cell clusters to be formed in Group 1, and none or little in Group 2, indicating differences in biofilm formation on Group 1 vs Group 2.Based on ImageJ calculation, control slides had an average percentage area for microcolonies, cell agregates, and single cells or clusters of 39.97 ± 9.99%, 8.96 ± 3.19%, and 1.39 ± 0.33%, respectively. Treatment with detergent significantly reduced percentages of microcolonies to 0.33 ± 0.68%, but increased single cell area to 5.27 ± 0.49%. Conclusion: ImageJ can be a valuable tool to quantify biofilm production in glass slides based on the number and percentage area of microcolonies, cell aggregates, and single cells or cell clusters.
