Abstract

This study aimed to analyze the effects of different concentrations of Aloe vera as a natural plant growth regulator (PGR) on the growth of Dendrobium ‘Arif’ orchids. The observed parameters included root length, stem height, and shoot height as indicators of vegetative growth. The experiment employed a completely randomized design (CRD) with five treatments: a control (0%) and Aloe vera extract at concentrations of 1%, 3%, 5%, and 7%, each with three replicates. Data were analyzed using one-way ANOVA, followed by Tukey’s HSD test at a 5% significance level. The results showed that Aloe vera had a significant effect on stem height (F = 2.712; p = 0.043) and root length (F = 5.896; p = 0.001), but no significant effect on shoot height (F = 0.359; p = 0.836). The 5% concentration produced the highest mean stem height (8.00 cm), exceeding that of the control (6.94 cm), 1% (6.89 cm), 3% (6.39 cm), and 7% (6.83 cm). For root length, the 5% concentration also yielded the highest value (8.98 cm), compared with 1% (7.76 cm), the control (6.40 cm), 7% (5.95 cm), and 3% (4.56 cm), and differed significantly according to Tukey’s HSD test. The non-significant response in shoot height suggests differences in physiological sensitivity among plant organs, with roots and stems being more responsive to auxins and gibberellins present in Aloe vera. Overall, Aloe vera extract shows potential as a natural PGR to support the vegetative growth of Dendrobium orchids, particularly in root and stem development.

Abstract

Anggrek Dendrobium spp. merupakan salah satu genus anggrek yang banyak dibudidayakan, namun pertumbuhannya tergolong lambat dan memerlukan suplai nutrisi tambahan untuk mendukung fase vegetatif. Pemanfaatan bahan alami sebagai pupuk organik cair (POC) dan zat pengatur tumbuh (ZPT) menjadi alternatif ramah lingkungan yang semakin banyak diteliti. Penelitian ini bertujuan untuk mengkaji efektivitas berbagai bahan organik alami sebagai sumber POC maupun ZPT dalam meningkatkan pertumbuhan Dendrobium spp. Penelitian disusun menggunakan metode literature review dengan menelusuri artikel ilmiah terbitan 2015–2025 dari jurnal bereputasi yang relevan dengan topik pupuk organik dan ZPT alami pada anggrek Dendrobium. Hasil telaah menunjukkan bahwa POC berbahan daun kelor, air kelapa, limbah rumah tangga fermentasi, dan air cucian beras mampu meningkatkan tinggi tanaman, jumlah daun, dan panjang akar, terutama pada konsentrasi 10–30%. Sementara itu, ZPT alami seperti ekstrak tomat, nutrisi organik, dan bahan organik kultur in vitro efektif merangsang pembentukan tunas, pemanjangan akar, serta peningkatan biomassa pada konsentrasi 10–20% atau dikombinasikan dengan POC 5–10 mL L⁻¹. Secara keseluruhan, bahan organik alami memiliki potensi besar dalam mendukung pertumbuhan Dendrobium spp. dan menjadi alternatif yang efisien, ekonomis, dan berkelanjutan dalam budidaya anggrek.
