“…Di sisi lain, untuk tanaman padi, diperoleh hasil peningkatan efisiensi penyerapan nitrgogen dari pupuk menuju tanaman dari rata-rata 40% ke 80% yang berefek pada peningkatan hasil tanaman dari 4,45 ke 6,35 ton/ha. Penelitian Jufri dan Rosjidi [19] menunjukkan bahwa pemanfaatan zeolit dengan dosis 70-80% hara N masih menghasilkan produksi padi yang sama dengan penggunaan pupuk konvensional atau rekomendasi. Dengan demikian pemakaian zeolit dapat menghemat pemakaian pupuk anorganik sebesar 20-50 persen.…”

Nitrogen merupakan unsur hara esensial, oleh karenanya ketersediaan nitrogen anorganik sangat penting dalam mendukung perkembangan bibit kelapa sawit. Adanya sifat urea yang lepas cepat, menyebabkan urea mudah hilang sebelum diserap oleh tanaman. Berbagai upaya telah dilakukan untuk mengubah sifat urea dari lepas cepat menjadi lepas lambat. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas pelapisan urea dengan zeolit dengan metode yang mudah. Urea dengan lapisan zeolit dibandingkan dengan urea tanpa lapisan zeolit selama tiga bulan aplikasi pemupukan bibit sawit main nursery. Penelitian ini menggunakan dua jenis zeolit yaitu zeolit non aktivasi dan zeolit aktivasi, dengan dua persentase yaitu 20% dan 40%. Adanya pelapisan zeolit menyebabkan penurunan higroskopisitas urea dan kelarutan urea pada larutan aquades. Selain itu pelapisan urea pada berbagai persentase dan berbagai tipe zeolit mampu menghasilkan pertumbuhan yang sama baiknya dengan pupuk urea tanpa zeolit. Hal ini menunjukkan bahwa baik zeolit yang diaktivasi maupun non aktivasi dapat dimanfaatkan dalam pelapisan urea yang berdampak pada penurunan jumlah dosis urea yang digunakan dalam pembibitan.

“…Zeolites and activated charcoal addition on the formulation could provide nitrogen slowly. Zeolites with 75-80% dosage of N could produce rice with the same amount as conventional fertilizer, therefore it could reduce the usage of synthetic fertilizer up to 25% (Jufri and Rosjidi, 2012).…”

Rice field soil quality in Rancaekek decreases gradually due to textile waste water to irrigation source. One of the heavy metal contaminant is chrome (Cr). As an effort to reduce Cr residue, bioagent-added organomineral nitrogen (abbreviated as BaON) fertilizer consisted of the mixture of urea, zeolite, activated charcoal, and plant compost enriched with bioagent (Bacillus subtilis) was added as a slow release fertilizer. This paper studied the effect of BaON fertilizer formulation towards total nitrogen content, pH and total Cr content in Rancaekek paddy soil. The experiment was designed in Randomized Block Design with six treatments and five replicates, consisted of: 0 (control), 150; 200; 250; 300; and 350 kg ha -1 . The result showed that the application of BaON fertilizer increased soil total nitrogen content and pH, and decrease Cr residue in Rancaekek paddy field soils. Application of 350 kg ha -1 of BaON fertilizer gave the highest increase of total nitrogen in 60 days after transplant (0.11%), while 300 kg ha -1 of BaON gave the highest increase in pH (6.18), and the application of 250 kg ha -1 of BaON gave the highest reduction of chrome (16.15 mg kg -1 ) in Rancaekek soils. This study suggests that application of Urea-zeolite-activated charcoal and bio-agent inoculated compost application could minimize Cr contaminated waste in the long-run.

This study aims to investigate the optimum dosage of Bokashi and Phonska NPK fertilizer on the growth and production of the Inpari 42 rice variety. This investigation was conducted at the agricultural location of Ulu Mowewe Village, Mowewe District, East Kolaka Regency. The experiment used was the Split Plot Design (RPT). The factorial pattern consists of two treatment factors, namely the Bokashi (B) treatment factor with three levels, namely: B1 = 1.2 kg/plot, B2 = 2.4 kg/plot, and B3 = 4.8 kg/plot, and the treatment factor Phonska NPK, which consists of three levels, namely N1 = 0.18 kg/plot, N2 = 0.36 kg/plot, and N1 = 0.54 kg/plot. Parameters observed in the study were: plant height, number of tillers, number of leaves, leaf length, leaf width, panicle length, number of panicles or clumps, number of grain or panicles, number of filled grain or panicles, the weight of 1000 grain grains, dry milled grain yield (GKG) per plot, Milled Dry Unhulled grain yield (GKG) per conversion. The data were processed using variance (ANOVA) and followed by the Least Significant Difference Test (LSD). Based on the results of the study, it can be concluded that the combined dose of Bokashi and Phonska NPK fertilizer significantly affected plant height (cm), the number of tillers, the number of leaves (strands), leaf length (cm), leaf width (cm), panicle length (cm), number/panicle, total grain/panicle, total grain/panicle, and yield of dry milled grain (GKG)/slot (kg), the yield of dry milled unhulled grain (GKG)/conversion (tons) The dose treatment of Bokashi and Phonska NPK showed that the optimum combination dose of Bokashi and Phonska NPK for the growth and yield of Inpari 42 rice was B3N2 (4.8 kg and 0.3 kg/plot).
