    Abstrak Peluang pemecahan masalah pelandaian produksi padi dapat melalui penerapan teknologi budidaya, yang bertujuan untuk memperbaiki lingkungan tumbuh tanaman, kesuburan tanah dan meningkatan efisiensi pemupukan. Pemanfaatan teknologi nano, seperti PPC Nano, di bidang pemupukan memiliki keunggulan lebih reaktif dan lebih efisien. Kombinasi pemupukan organik cair dari PPC Nano dan inorganik granul NPK dapat meningkatkan keseimbangan hara sekaligus meningkatkan efisiensi pemupukan. Penelitian bertujuan untuk mengetahui dosis optimum pupuk organik cair (PPC) yang dikombinasikan dengan pengurangan dosis pupuk NPK inorganik, telah dilakukan di Kebun Percobaan Sukamandi pada MK-I 2012. Penelitian menggunakan rancangan acak kelompok, dengan 12 perlakuan dan 3 ulangan. Perlakuan terdiri dari kontrol (0 PPC dan 0 NPK); 450 ml/ ha PPC- 0 NPK; kontrol jenis PPC lain; dan 9 perlakuan lainnya yang merupakan kombinasi PPC dengan pengurangan dosis NPK. Konsentrasi PPC masing-masing 150, 350 dan 450 ml/ha dikombinasikan dengan pupuk NPK dosis 100% NPK (135 N-36 P2O5 – 60 K2O), 75% NPK dan 50% NPK. Hasil penelitian menunjukkan bahwa Hasil panen GKG yang diperoleh dengan pemberian hanya 450 ml PPC Nano/ha tanpa pupuk NPK mencapai 6563 kg/ha atau meningkat 38,9% jika dibandingkan perlakuan Kontrol_tanpa pupuk NPK; Reduksi pupuk N-P-K sebesar 75% Dosis, tidak menurunkan hasil panen GKG jika dikombinasikan dengan pemberian PPC Nano. Fenomena menarik bahwa pengurangan dosis pupuk kimia hingga 50%N-50%P-30%K namun dikombinasikan dengan pemberian PPC Nano tidak menurunkan produksi padi. Hasil tertinggi diperoleh dari perlakuan reduksi 50% NPK yang dikombinasikan dengan penyemprotan 300 ml PPC Nano/ha; Penyemprotan PPC mampu mensubtitusi penggunaan pupuk kimia NPK hingga 50% dan mampu meningkatkan hasil jika dibandingkan hasil pada dosis pupuk rekomendasi. Abstract Nano Size Organic Liquid Fertilizer to Improve Fertilization Efficiency in Lowland Rice; The phenomenon of rice yield plateauing can be solved by technology applications aimed at improving the environment, soil fertility and increase fertilization efficiency. Nano-fertilizers, such as PPC Nano, have the advantage of being more reactive and more efficient. The combination of liquid organic fertilizer from PPC Nano and inorganic NPK granules can improve nutrient balance while increasing fertilizer efficiency. The aim of the study was to determine the optimum dose of liquid organic fertilizer (PPC) combined with a reduction of inorganic NPK fertilizer dosage, which was carried out at the Sukamandi Experimental Station in the Dry Season 2012. The study used a randomized block design, with 12 treatments and 3 replications. The treatment consists of controls (0 PPC and 0 NPK); 450 ml/ha of PPC-0 NPK; control of other types of PPC; and 9 other treatments which were a combination of PPC with a reduction in the dose of NPK. The PPC concentrations were 150, 350 and 450 ml/ha respectively combined with NPK fertilizer at a dose of 100% NPK (135 N-36 P2O5 - 60 K2O), 75% NPK and 50% NPK. The results showed that the yield obtained by giving only 450 ml of PPC Nano/ha without NPK fertilizer reached 6563 kg/ha or increased by 38.9% compared to the control treatment without NPK fertilizer; The reduction of N-P-K fertilizer by 75% dosage in combination with PPC-Nano application did not significantly reduce the grain yield. An interesting trend was that the reduction in chemical fertilizer dosages to even 50% N-50% P-30% K but combined with the application of PPC Nano did not reduce rice production. The highest yield in this experiment is obtained from treatment 50% NPK reduction combined with 300 spraying ml PPC/ha); The grain yield in the 100% NPK treatment was not significantly different compared to the 75% NPK reduction treatment even 50% N-50% P-30% K indicated that PPC spraying was able to substitute NPK chemical fertilizer use up to 50%, it could even increase yield when compared with yield under recommended fertilizer dose
