Abstract

Tridax procumbens L. and Aloe vera L. are plants commonly used in the treatment of burns. This study was conducted to determine the effect of giving a combination gel of T. procumbens and A. vera leaf extract on second-degree burn healing in mice. This study used 24 male mice (Mus musculus) which were divided into four treatment groups, namely positive control (KP, Bioplacenton®); negative control (KN, gel base); leaf extract of T. procumbens 0.5% and A. vera 0.5% (P1); and leaf extract of T. procumbens 1% and A. vera 0.5% (P2). The process of inducing burns on the backs of mice requires the use of a 1x1 cm iron, which is subjected to heat in a fire for three minutes. The iron is placed on the mice's back for five seconds, which leads to the development of a second-degree burn. The gel was applied twice a day for 21 days. The highest level of burn wound healing was recorded with the Bioplacenton® treatment, which achieved a full recovery of 100% on day 15. Following this, the combined gel treatment of 1% T. procumbens leaf extract and 0.5% A. vera also reached 100% healing by day 18. While it may not be as potent as Bioplacenton®, the gel formulation containing 1% T. procumbens and 0.5% A. vera leaf extract presents a viable alternative for treating second-degree burns.

Abstract

Waterbird diversity in Tondano Lake reflects ecological degradation caused by water-hyacinth invasion and sedimentation. This study analyzed the diversity and abundance of waterbirds in Tondano Lake, Indonesia, across wet (February-May) and dry (June-October) seasons in 2025 to assess their role as bioindicators of ecosystem health. Multi-season observations were carried out monthly along a 6.5 km transect at ten strategic points. Eight waterbird species from three families were recorded, with Egretta garzetta being the most abundant (29.1%) and Alcedo atthis the least (4.8%). The Shannon-Wiener diversity index (H' = 1.92) indicates a moderate level of species diversity, which reflects a pattern of ecological simplification when compared to pristine tropical lakes such as Lake Sentarum (H' = 2.5). Waterbird abundance showed significant negative correlations with water hyacinth density (r = -0.68, p = 0.032) and water depth (r = -0.72, p = 0.019), revealing that invasive vegetation and shoaling are primary drivers of habitat loss. These findings demonstrate that waterbirds function as sensitive bioindicators of ecological stress, highlighting the urgent need for integrated watershed management to prevent further community collapse.

Abstract

Latar belakang penelitian ini adalah rendahnya hasil belajar siswa pada mata pelajaran IPA. Berdasarkan hasil observasi serta wawancara di SMP Negeri 6 Langowan, pembelajaran di kelas hanya berlangsung satu arah, siswa kurang memperhatikan pelajaran, dan siswa dominan hanya mencatat materi. Penelitian ini bertujuan untuk meningkatkan hasil belajar siswa kelas IX C SMP Negeri 6 Langowan melalui penerapan model pembelajaran PBL khususnya pada materi sistem perkembangbiakan tumbuhan. Penelitian ini menggunakan jenis penelitian tindakan kelas (PTK). Penelitian ini dilaksanakan di kelas IX C SMP Negeri 6 Langowan yang berjumlah 25 siswa. Hasil penelitian siklus I menunjukkan 7 siswa tuntas dengan persentase 28% dan 18 siswa tidak tuntas dengan persentase 72%. Pada pelaksanaan siklus II, 24 siswa tuntas dengan persentase 96% sedangkan 1 siswa tidak tuntas dengan persentase 4%. Kesimpulan penelitian ini bahwa penerapan model pembelajaran problem based learning mampu meningkatkan hasil belajar IPA di kelas IX C SMP Negeri 6 Langowan materi sistem perkembangbiakan tumbuhan.
