Abstract

 Sembung rambat umumnya tumbuh dominan pada areal kelapa sawit belum menghasilkan hingga dapat membelit atau menutupi tanaman budidaya. Penggunaan bioherbisida merupakan alternatif untuk pengendalian gulma yang tumbuh di tanaman budidaya, salah satu cara memacu pertumbuhan gulma yaitu dengan herbisida daun ketapang. Penelitian ini bertujuan untuk mengetahui apakah ekstrak daun ketapang mampu menghambat pertumbuhan sembung rambat.Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) nonfaktorial yang terdiri dari 5 taraf perlakuan konsentrasi (0%;10%; 25%; 50%; 75%) dengan 5 kali ulangan sehingga diperoleh 25 satuan percobaan. Terhadap pertumbuhan gulma sembung rambat dengan parameter pengamatan tinggi tanaman, jumlah daun dan hari kematian. Hasil analisa dan pengamatan setelah aplikasi bioherbisida ekstrak daun ketapang menunjukkan bahwa ada pengaruh terhadap tinggi tanaman, jumlah daun dan hari kematian. Berdasarkan hasil analisa dan pengamatan konsentrasi 25%, 50% dan 75% berpengaruh nyata terhadap penghambatan pertumbuhan gulma sembung rambat dibandingkan tanpa pengaplikasian bioherbisida ekstrak daun ketapang. Konsentrasi efektif bioherbisida ekstrak daun ketapang adalah konsentrasi 50%.              Keywords : Sembung Rambat; Ketapang; Bioherbisida.

Abstract

This study aimed to determine the effect of liquid organic fertilizer derived from moringa leaves on the growth of rubber seedlings (Hevea brasiliensis) grown in Ultisol (Red Yellow Podzolic) soil. The research was conducted at the Experimental Garden of Ketapang State Polytechnic from March to July 2024 using a non-factorial Completely Randomized Design with five treatment levels and four replications. The observed parameters included seedling height, stem diameter, number of leaves, root volume, and dry weight of seedlings. The results showed that the application of moringa leaf liquid organic fertilizer improved the growth of rubber seedlings across all observed parameters. The concentration of 500 mL/L produced the best results, with an average seedling height of 59.89 cm, stem diameter of 4.48 mm, number of leaves of 2.44, root volume of 7 mL, and dry weight of 9.40 g. This improvement is presumably due to the presence of essential nutrients and growth hormones in moringa leaves, which enhance soil properties and support plant physiological processes. Therefore, moringa leaf liquid organic fertilizer has the potential to be used as an alternative fertilization method to improve the quality of rubber seedlings in Ultisol soils.

Abstract

Coffee is a plantation commodity with significant economic value in Indonesia and globally. Efforts to increase nutrient availability and improve the chemical properties of alluvial soil require the addition of liquid organic fertilizer made from rice straw waste. This study aimed to determine the effect of applying liquid organic fertilizer (POC) made from rice straw waste on the growth of Robusta coffee seedlings in alluvial soil.This study used a non-factorial completely randomized design (CRD) consisting of five treatments. Each treatment had five replications, resulting in 25 experimental units, each consisting of three plant samples, for a total of 75 samples. The treatments were: K0: No POC Application, K1: Concentration 200 mL/L, K2: Concentration 250 mL/L, K3: Concentration 300 mL/L, and K4: Concentration 350 mL/L. The data were analyzed statistically using Analysis of Variance (ANOVA). If a significant effect was found, the Duncan Multiple Range Test (DMRT) was used at the 5% level. Rice straw waste organic fertilizer (POC) at a concentration of 250 mL was the best for increasing leaf number, root length, and plant dry weight. Rice straw waste organic fertilizer at a concentration of 300 mL was the best for increasing plant height and leaf width. Meanwhile, rice straw waste organic fertilizer at a concentration of 350 mL was the best for increasing stem diameter.
