Abstract

Ornamental plants have aesthetic roles and environmental benefits, but their care often requires chemicals that are less environmentally friendly. This study aims to evaluate the potential of young coconut water (Cocos nucifera) as a natural plant growth regulator (PGR) through a literature study. Coconut water is rich in nutrients, growth hormones (auxins, cytokinins, gibberellins), and other bioactive compounds, which can support various aspects of ornamental plant growth. The literature study included 15 relevant studies from 2016–2024, which evaluated the effect of coconut water concentration on various parameters, such as number of leaves, root length, and number of shoots in various ornamental plant species. The results showed that coconut water provided significant benefits, especially at concentrations of 15–20%, although plant responses varied depending on species and environmental conditions. In the in vitro culture method, coconut water was shown to replace synthetic hormones such as cytokinins with high effectiveness. The combination of coconut water with other ingredients, such as peptone and gibberellins, also increased plant growth, although some studies noted insignificant effects under certain conditions. These findings confirm that coconut water can be an economical and sustainable natural PGR alternative to enhance the growth of ornamental plants. However, further research is needed to optimize its use in various types of plants and environments.

Abstract

Ikan lele (Clarias sp.) merupakan ikan air tawar yang banyak dibudidayakan di Indonesia. Sistem akuaponik dapat menghemat lahan dan meningkatkan efisiensi pemanfaatan hara. Tanaman kangkung (Ipomoea aquatica) dan selada (Lactuca sativa) merupakan jenis sayuran yang populer di Indonesia. Maka dari itu, penelitian yang bertujuan untuk mengukur pertumbuhan dan kelangsungan hidup benih ikan lele (Clarias gariepinus) pada sistem akuaponik dengan jenis tanaman yang berbeda yaitu menggunakan tanaman kangkung dan selada. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri atas tiga perlakuan, yaitu Perlakuan P0 dengan pemberian pakan pelet (Kontrol), Perlakuan P1 dengan pertumbuhan tanaman kangkung dan pemberian pakan pelet, dan Perlakuan P2 dengan pertumbuhan tanaman selada dan pemberian pakan pelet). Data yang diperoleh dianalisis menggunakan Analysis of Variance (ANOVA). Penelitian selama 6 minggu menunjukkan bahwa pertumbuhan mutlak bobot tubuh benih ikan lele tertinggi terdapat pada perlakuan kontrol (P0) sebesar 11,03 g dan pertumbuhan mutlak panjang tubuh tertinggi juga terdapat pada perlakuan kontrol (P0) sebesar 4,03 cm. Laju pertumbuhan spesifik (SGR) tertinggi terdapat pada perlakuan kontrol (P0). Tingkat kelangsungan hidup (SR) tertinggi benih ikan lele terdapat pada Perlakuan I (P1) dengan tanaman kangkung sebesar 92,5%. Pertumbuhan tanaman akuatik menunjukkan bahwa tanaman kangkung (P1) memiliki tinggi rata-rata 9,25 cm, lebar daun 0,6 cm, dan 5 daun, sedangkan selada (P2) memiliki tinggi rata-rata 1,87 cm, lebar daun 0,93 cm, dan 2 daun. Kualitas air selama penelitian relatif stabil dengan suhu berkisar antara 26-33°C dan nilai pH antara 7-7,9.

Abstract

This study aims to assess the effect of young coconut water concentration on the growth of Dendrobium orchids. The research was conducted for 4 months at Candi Orchid Production House, Semarang, with a one-factor completely randomized design (CRD) and four treatments of young coconut water concentration (0 mL/L, 100 mL/L, 150 mL/L, 200 mL/L), each with five replications. Parameters observed included number of shoots, root length, and plant height. Data were analyzed using ANOVA and Duncan's further test at the 5% level. The results showed that the application of young coconut water had no significant effect on the number of shoots and root length (p > 0.05), but had a significant effect on plant height (p = 0.003), especially at a concentration of 100 mL/L. The predominance of cytokinin hormones in coconut water likely plays a role in stimulating stem growth, while its effects on shoots and roots require interactions with other hormones. Although coconut water contains essential nutrients, its composition may not be fully suitable for the physiological needs of orchids in the seedling phase.
