Abstract: | Zeoponik merupakan media tumbuh tanaman (MTT) hasil inovasi yang
tersusun atas bahan dasar zeolit, kompos, dan cocopeat disertai pupuk makro dan
mikro dalam jumlah tertentu. Zeoponik pada umumnya digunakan sebagai MTT
tanaman hias dan sayuran. Bagi tanaman yang menghasilkan buah seperti tomat dan
cabai rawit, zeoponik memerlukan tambahan pupuk makro khususnya fosfor (P)
dan kalium (K) karena kedua unsur tersebut berperan sangat penting dalam
pembentukan buah. Penelitian ini bertujuan menentukan dosis pupuk P dan K yang
tepat pada MTT zeoponik untuk tanaman tomat (Solanum lycopersicum L.) dan
cabai rawit (Capsicum frutescens L.) serta mengetahui perubahan sifat-sifat kimia
MTT zeoponik setelah penambahan pupuk P dan K. Penelitian disusun
menggunakan model rancangan acak lengkap (RAL) faktor tunggal berupa dosis
pupuk P dan K menggunakan tanaman tomat dan cabai rawit pada MTT zeoponik.
Penelitian terdiri atas empat perlakuan, yaitu dengan penambahan SP-36 0 g/l dan
KCl 0 g/l; SP-36 0,67 g/l dan KCl 0,40 g/l; SP-36 1,00 g/l dan KCl 0,60 g/l; serta
SP-36 1,33 g/l dan KCl 0,80 g/l yang secara berturut-turut ditandai dengan simbol
PK0, PK1, PK2, dan PK3. Pertumbuhan dan produksi tanaman diamati serta
dilakukan analisis sifat-sifat kimia terhadap MTT zeoponik. Berdasarkan
pertumbuhan dan produksi tanaman, perlakuan PK2 (penambahan SP-36 1,00 g/l
dan KCl 0,60 g/l) merupakan dosis optimal untuk tanaman tomat serta perlakuan
PK1 (penambahan SP-36 0,67 g/l dan KCl 0,40 g/l) merupakan dosis optimal untuk
tanaman cabai rawit. Penambahan SP-36 dan KCl menunjukkan terjadinya
peningkatan nilai pH, DHL, P-tersedia, C-organik, KTK, dan K-dd pada MTT
zeoponik. Zeoponic is an innovative plant growth medium (PGM) composed of zeolite, compost, and cocopeat base materials accompanied by a certain amount of macro and micro fertilizers. Zeoponic is generally used as PGM for ornamental plants and vegetables. For fruit-bearing plants such as tomatoes and cayenne pepper, zeoponics requires additional macro fertilizers, especially phosphorus (P) and potassium (K) because both elements play a very important role in fruit formation. This study aims to determine the appropriate doses of P and K fertilizers on zeoponic PGM for tomato (Solanum lycopersicum L.) and cayenne pepper (Capsicum frutescens L.) plants and to determine changes in the chemical properties of zeoponic PGM after the addition of P and K fertilizers. The research was structured using a single-factor completely randomized design (CRD) model in the form of doses of P and K fertilizers using tomato and cayenne pepper plants on zeoponic PGM. The study consisted of four treatments, namely with the addition of 0 g/l SP-36 and 0 g/l KCl, 0.67 g/l SP-36 and 0.40 g/l KCl, 1.00 g/l SP-36 and 0.60 g/l KCl, and 1.33 g/l SP-36 and 0.80 g/l KCl which are respectively marked with the symbols PK0, PK1, PK2, and PK3. Plant growth and production were observed and chemical properties of zeoponic PGM were analyzed. Based on plant growth and production, PK2 treatment (addition of SP-36 1.00 g/l and KCl 0.60 g/l) is the optimal dose for tomato plants and PK1 treatment (addition of SP-36 0.67 g/l and KCl 0.40 g/l) is the optimal dose for cayenne pepper plants. The addition of SP-36 and KCl showed an increase in pH, EC, P-available, C-organic, CEC, and K-dd values in zeoponic PGM. |
