MUHAMMAD MUMTAZ PERMANA AGUNG. Formulasi dan Karakterisasi Pupuk Hidroponik Larut Air Berbentuk Tablet Berbuih. Dibimbing oleh FARIDA LAILA dan ADIT RIZKY WICAKSONO.

Penurunan luas lahan pertanian dan tantangan iklim mendorong sistem hidroponik sebagai salah satu solusi pertanian modern. Sistem ini membutuhkan pupuk yang mudah larut dan efisien. Penelitian ini bertujuan mengembangkan dan mengevaluasi pupuk hidroponik larut air (WSF) berbentuk tablet Effervescent sebagai alternatif praktis terhadap pupuk cair, serbuk, dan granul. Tahapan pembuatan pupuk WSF melalui formulasi dan tableting, tablet pupuk diuji kualitasnya melalui analisis fisikokimia. Pengujian fisik meliputi kekerasan tablet, pH, konduktivitas listrik, dan total padatan terlarut. Sementara itu, analisis kimia mencakup penentuan kadar nitrogen total, fosfor total, dan kalium. Formula V7 teridentifikasi sebagai formula terbaik dengan kekerasan mendekati standar (2 KgF), pH netral (6,5–7,0), EC 3540 µS/cm, TDS 1770 ppm, serta kandungan nitrogen dan kalium yang seimbang. Formula ini juga menunjukkan efisiensi pelarutan tinggi dan kestabilan nutrisi, menjadikannya potensial untuk aplikasi praktis dalam sistem hidroponik.

MUHAMMAD MUMTAZ PERMANA AGUNG. Formulation and Characterization of Water Soluble Hydroponic Fertilizer in the Form of Effervescent Tablets. Supervised by FARIDA LAILA and ADIT RIZKY WICAKSONO.

Decline in agricultural land area and climate challenges had prompted the adoption of hydroponic systems as one of the solutions for modern agriculture. This system required fertilizers that were easily soluble and efficient. This study aimed to develop and evaluate water-soluble hydroponic fertilizer (WSF) in the form of effervescent tablets as a practical alternative to liquid, powder, and granular fertilizers. The production of WSF fertilizer involved formulation and tableting, with the fertilizer tablets tested for quality through physicochemical analysis. Physical testing included tablet hardness, pH, electrical conductivity, and total dissolved solids. Meanwhile, chemical analysis included determining the total nitrogen, total phosphorus, and potassium content. Formula V7 was identified as the best formula with hardness close to the standard (2 KgF), neutral pH (6.5–7.0), EC 3540 µS/cm, TDS 1770 ppm, balanced nitrogen and potassium content. This formula also demonstrated high solubility efficiency and nutrient stability, making it a promising candidate for practical application in hydroponic systems.
