Effect of IAA and BAP Application on Vegetative Growth of Timun Suri (Cucumis melo L.) Cultivated in an Aeroponic System / Pengaruh Pemberian IAA Dan BAP Terhadap Pertumbuhan Vegetatif Timun Suri (Cucumis melo L.) Pada Sistem Aeoroponik

Suri cucumber (Cucumis melo L.) is a local horticultural commodity with high economic value; however, its productivity remains relatively low due to the use of conventional cultivation systems. This study aims to determine the effect of Indole Acetic Acid (IAA) and Benzyl Amino Purine (BAP) application and their interaction on the vegetative growth of Suri cucumber cultivated in a vertical aeroponic system. A factorial completely randomized design (CRD) with two factors was employed: IAA concentration (0, 50, and 100 ppm) and BAP concentration (0, 25, and 50 ppm), each with three replications. The observed parameters included plant height, number of leaves, and root length. Data were analyzed using two-way analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results showed that the application of IAA and BAP significantly affected several vegetative growth parameters of Suri cucumber, particularly plant height. The interaction between IAA and BAP exhibited a synergistic response in enhancing vegetative growth in the aeroponic system. It can be concluded that the combination of IAA and BAP in a vertical aeroponic system has the potential to serve as an effective and sustainable alternative cultivation technology to increase Suri cucumber productivity.

Timun suri (Cucumis melo L.) merupakan komoditas hortikultura lokal yang memiliki nilai ekonomis tinggi, namun produktivitasnya masih relatif rendah akibat penggunaan sistem budidaya konvensional. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian Indole Acetic Acid (IAA) dan Benzyl Amino Purine (BAP) serta interaksinya terhadap pertumbuhan vegetatif timun suri pada sistem aeroponik vertikultur. Penelitian menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) faktorial dua faktor, yaitu konsentrasi IAA (0, 50, dan 100 ppm) dan konsentrasi BAP (0, 25, dan 50 ppm) dengan tiga ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan panjang akar. Data dianalisis menggunakan analisis varian (ANOVA) dua arah dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa pemberian IAA dan BAP berpengaruh nyata terhadap beberapa parameter pertumbuhan vegetatif timun suri, khususnya tinggi tanaman. Interaksi antara IAA dan BAP memberikan respons sinergis dalam meningkatkan pertumbuhan vegetatif pada sistem aeroponik. Dapat disimpulkan bahwa kombinasi IAA dan BAP pada sistem aeroponik vertikultur berpotensi menjadi alternatif teknologi budidaya yang efektif dan berkelanjutan untuk meningkatkan produktivitas timun suri.
