Sintesis dan Analisis Sifat Fisis Hidroton Berbasis Ball Clay dan Cocopeat Sebagai Media Tanam Hidroponik

Abstract

Research on hydroton analysis based on ball clay and cocopeat has been conducted. This study aims to determine how the effect of cocopeat addition on physical properties of hydrotons in term of porosity, bulk density, and absorption. Cocopeats which were added to ball clay varies from 5%, 10%, 15%, 20%, and 25%. Hydrotons were synthesized using a furnace at 950°C for 4 hours with a holding time for 2 hours. Based on the characterization results, the addition of cocopeat affected the physical properties of hydrotons, especially porosity and water absorbance of hydrotons which were positively correlated 94.5% and 96% respectively. Meanwhile, the bulk density negatively correlated at 98.1%. The more cocopeats added, the higher porosity and water absorbance, the contrary, the bulk density decreased gradually.

Pengaruh Modifikasi Media Tanam Hidroton dan Zat Pengatur Tumbuh terhadap Produktivitas Tanaman Pakcoy (Brassica Rapa L.) Secara Hidroponik Sistem Wick

“…Selain itu kelemahan dari media tanam hidroton yaitu memiliki daya simpan air dalam instalasi hidroponik yang rendah yang dapat berpengaruh terhadap pertumbuhan tanaman (Hafizah et al, 2019). Penambahan modifikasi dengan bahan organik mampu menyebabkan hidroton memiliki interkoneksi pori yang sangat tinggi dan mampu meningkatkan daya serap air (Maryam et al, 2020). Kualitas tanaman yang baik seperti daun pakcoy sehat dan lebar perlu adanya tambahan pemberian zat pengatur tumbuh pada daun tanaman.…”
