Abstract

Penyakit Demam Berdarah Dengue (DBD) masih menjadi tantangan kesehatan masyarakat yang serius di Indonesia, sehingga diperlukan inovasi pengendalian vektor yang aman bagi ekosistem guna menggantikan insektisida kimia yang berisiko memicu resistensi dan pencemaran lingkungan. Penelitian ini menguji efektivitas larvasida alami dari ekstrak daun kemangi (Ocimum basilicum), daun jeruk nipis (Citrus aurantifolia), dan daun sereh (Cymbopogon citratus) terhadap mortalitas jentik nyamuk Aedes aegypti. Melalui metode eksperimen murni dengan Rancangan Acak Lengkap (RAL), sebanyak 1.125 jentik instar III–IV dipaparkan pada empat variasi konsentrasi, yaitu 0,14 ml, 0,16 ml, 0,18 ml, dan 0,20 ml selama 24 jam. Hasil penelitian mengungkapkan perbedaan signifikan pada daya bunuh ketiga ekstrak tersebut. Ekstrak daun jeruk nipis menunjukkan efektivitas tertinggi dengan persentase kematian mencapai 85,33% pada konsentrasi maksimal, diikuti oleh ekstrak daun kemangi sebesar 48,0%, dan ekstrak daun sereh dengan daya bunuh terendah sebesar 32,0%. Tingginya angka mortalitas pada ekstrak jeruk nipis diduga karena kandungan senyawa limonoid dan flavonoid yang bekerja efektif sebagai racun saraf dan pernapasan bagi jentik. Sebaliknya, meskipun kemangi dan sereh mengandung minyak atsiri, konsentrasi yang diuji belum mampu mencapai standar minimal mortalitas WHO sebesar 90%. Simpulannya, ekstrak daun jeruk nipis memiliki potensi paling kuat sebagai biolarvasida mandiri yang praktis dan ekonomis bagi masyarakat. Optimalisasi pemanfaatan bahan nabati ini diharapkan dapat memperkuat program pemberantasan sarang nyamuk yang ramah lingkungan dan berkelanjutan.

Abstract

Indoor air quality in inpatient wards constitutes a critical dimension of hospital environmental health, as it directly intersects with patient comfort, occupational safety for health personnel, and the prevention of healthcare associated infections. This study aimed to evaluate the physical air environmental quality of inpatient rooms at Budi Agung Hospital using selected environmental health parameters. A descriptive observational design with a cross sectional approach was employed. Data were obtained through direct measurements of air temperature, relative humidity, air flow velocity, lighting intensity, noise level, PM 2,5 concentration, PM 10 concentration, and airborne bacterial count. Physical air parameters were measured at 71 observation points, while airborne bacterial counts were assessed before and during patient visiting hours. The findings demonstrate that air temperature, relative humidity, and air flow velocity were the principal parameters that failed to comply with the required environmental health standards. Only 1 of 71 temperature measurement points met the standard, whereas 70 points did not. For relative humidity, 55 of 71 points failed to meet the standard, while for air flow velocity, 61 of 71 points were non compliant. Lighting intensity showed a more favorable profile, with 66 of 71 measurement points meeting the required standard. Noise level, PM 2,5 concentration, and PM 10 concentration met the standards across all measurement points. Airborne bacterial counts also remained within the acceptable standard in all examined rooms, although higher counts were observed during patient visiting hours compared with the period before visiting hours. These findings indicate that the physical air environment of inpatient rooms requires targeted improvement, particularly in the regulation of air temperature, relative humidity, and air flow velocity. Strengthening routine environmental monitoring, optimizing ventilation performance, ensuring scheduled maintenance of air conditioning systems, and controlling visitor density are necessary to establish a safer, more comfortable, and healthier inpatient care environment.
