Abstract

Background: Impacted teeth, hindered from erupting normally due to space constraints, obstruction by neighboring teeth, or an abnormal eruption pathway, often necessitate surgical intervention known as odontectomy. Silk sutures are commonly used in this procedure, yet they may serve as sites for bacterial colonization, potentially leading to infection. Following odontectomy, antibiotics are typically prescribed. Purpose: This study aims to identify the bacterial profile adhering to silk sutures and analyze antibiotic sensitivity patterns in patients undergoing odontectomy. Methods: A descriptive study employing consecutive sampling of patients after odontectomy was conducted between May and November 2021 at Arifin Achmad General Hospital, Riau Province, Indonesia. Sutures were removed within 14 days of surgery, after which the silk was identified and subjected to antibiotic sensitivity testing using the Kirby–Bauer method. Results: Of the bacteria detected in the silk sutures, 53.7% were Gram positive, including Streptococcus sp. (33.3%) and Staphylococcus aureus (13%), and 46.3% were Gram negative, such as Enterobacter sp. (20.4%) and Klebsiella sp. (16.7%). Among the multi-resistant strains, methicillin-resistant S. aureus (MRSA) accounted for 57.1%. The Gram-positive bacteria exhibited the highest sensitivity to levofloxacin, whereas the Gram-negative bacteria showed sensitivity to ceftazidime, levofloxacin, and meropenem. Conclusion: The most dominant Gram-positive bacteria were Streptococcus sp. and S. aureus, whereas the most dominant Gram-negative bacteria were Enterobacter sp. and Klebsiella sp. Levofloxacin, ceftazidime, and meropenem emerged as the most effective antibiotics following odontectomy. Multidrug-resistant bacteria, exemplified by MRSA, were identified within the oral cavity.

Abstract

Penelitian ini merancang dan mengembangkan sistem pembangkit listrik tenaga surya yang memanfaatkan kombinasi solar cell, modul termoelektrik, dan sistem kompresi uap pada smart halte untuk mendukung kebutuhan energi mandiri dan berkelanjutan. Sistem ini dirancang untuk mengoptimalkan konversi energi matahari menjadi listrik melalui integrasi teknologi fotovoltaik dan termoelektrik yang memanfaatkan perbedaan suhu, serta memanfaatkan sistem kompresi uap untuk meningkatkan efisiensi energi. Komponen-komponen ini diintegrasikan untuk menciptakan solusi multifungsi yang dapat menyediakan daya listrik secara stabil bagi infrastruktur halte pintar. Uji coba dilakukan untuk mengevaluasi kinerja sistem dalam menghasilkan daya listrik yang mencukupi serta kestabilan operasional di berbagai kondisi lingkungan. Pengujian ini mencakup pengamatan terhadap efisiensi energi total, respons sistem terhadap fluktuasi suhu, dan kemampuan adaptasi teknologi kompresi uap untuk meningkatkan output daya. Data yang diperoleh menunjukkan bahwa integrasi antara solar cell, termoelektrik, dan sistem kompresi uap dapat mengurangi ketergantungan pada sumber energi eksternal serta meningkatkan keandalan pembangkitan listrik di lingkungan perkotaan. Implementasi sistem ini di smart halte dapat membantu menciptakan ruang publik yang lebih ramah lingkungan dan hemat energi, serta berkontribusi dalam mengurangi emisi karbon.
