Abstract

Penanganan cedera kulit akibat luka bakar menuntut intervensi terapeutik yang mampu mempercepat regenerasi jaringan sekaligus menekan risiko komplikasi. Potensi sediaan topikal berbasis bahan alam seperti lidah buaya (Aloe vera (L.)) dapat dikembangkan karena kaya akan kandungan senyawa bioaktif. Penelitian eksperimental ini menguji efektivitas gel ekstrak lidah buaya dalam memulihkan luka bakar pada mencit (Mus musculus) jantan. Pengujian menerapkan Rancangan Acak Lengkap (RAL) dengan empat kelompok perlakuan: tiga variasi konsentrasi gel (15%, 30%, dan 45%) serta satu kelompok kontrol positif. Parameter evaluasi mencakup sifat fisik gel, meliputi organoleptik, homogenitas, pH, daya sebar, dan daya lekat, serta tingkat pemulihan luka yang diukur melalui penyusutan diameter luka selama pengamatan 25 hari. Data kuantitatif dianalisis secara statistik dan deskriptif. Hasil evaluasi fisik mengonfirmasi sediaan gel bersifat homogen, stabil dalam penyimpanan, bertekstur semi-padat, dan berwarna bening kehijauan. Seluruh sediaan uji terbukti memperkecil diameter luka. Namun, konsentrasi 45% mencatatkan persentase kontraksi luka terbesar, melampaui konsentrasi yang lebih rendah maupun kelompok kontrol positif. Sediaan gel ekstrak Aloe vera dengan konsentrasi optimal 45% berpotensi kuat sebagai kandidat sediaan topikal untuk pemulihan luka bakar.

Abstract

Bukit Cendana, located in Pesawaran Regency, Indonesia, is an ecosystem with high biodiversity that provides suitable habitats for birds. This study aimed to identify bird species, assess bird diversity, and determine their conservation status in Bukit Cendana. The study was conducted from May to June 2025 using the point count method at three observation stations, with observations conducted in the morning and afternoon and repeated three times. Species were identified using standard bird identification guides. The Shannon–Wiener diversity index (H′) was 1.22 at Station 1, 1.01 at Station 2, and 2.27 at Station 3, indicating moderate diversity at all stations (1 < H′ < 3). A total of 24 bird species belonging to 17 families were recorded, comprising 959 individuals. One protected species, the Hill Barbet (Megalaima oorti), was recorded according to Indonesian conservation regulations. Overall, Bukit Cendana supports a moderately diverse bird community with conservation value. Therefore, habitat management should prioritize vegetation protection, reduction of human disturbance and infrastructure-related impacts, and regular monitoring of bird diversity and protected species to support sustainable biodiversity conservation.
