Utilization of hanjeli seed skin as organic silica fertilizer in influencing the growth, P and Si absorption, and yield of hanjeli (Coix lacryma-jobi L.)This experiment was conducted to determine the effect of hanjeli seed shell as organic silica fertilizer on plant uptake and hanjeli pulut (Coix lacryma-jobi L.) yield on Inceptisol. The experiment was conducted in Experimental Station of Agriculture Faculty of Universitas Padjadjaran, Jatinangor, Sumedang Regency, West Java Province. The research was carried out in the altitude of 822 meters above sea level (asl) from May 2017 to October 2017. The method used was a Randomized Block Design (RBD) consisting of ten treatments with three replications, i.e. control, NPK standard, NPK + ¼ silica emulsion, NPK + ½ silica emulsion, NPK + ¾ silica emulsion, NPK + 1 emulsion of ash silica, NPK + ¼ nano colloidal silica, NPK + ½ nano colloidal silica, NPK + ¾ nano colloidal silica, and NPK + 1 nano colloidal silica. The results showed that the application of silica fertilizer influenced the absorption and the yield of hanjeli plant. The treatment of NPK + 1 colloidal nano silica gave the highest hanjeli yield of 210.63 g/plant.Keywords: Hanjeli seed skin, Organic silica fertilizer, Plant absorption, YieldABSTRAKPercobaan ini dilakukan untuk mengetahui pengaruh pemberian kulit biji hanjeli sebagai pupuk silika organik terhadap pertumbuhan, serapan tanaman, dan hasil hanjeli pulut (Coix lacryma-jobi L.) pada Inceptisol. Percobaan dilaksanakan di Kebun Percobaan Fakultas Pertanian, Universitas Padjadjaran, Jatinangor, Kabupaten Sumedang, Provinsi Jawa Barat. Lokasi penelitian berada pada ketinggian 822 meter di atas permukaan laut (dpl) pada bulan Mei 2017 sampai dengan Oktober 2017. Metode yang digunakan adalah Rancangan Acak Kelompok (RAK) yang terdiri dari sepuluh perlakuan dengan tiga kali ulangan yaitu kontrol, NPK standar, NPK + ¼ emulsi abu silika, NPK + ½ emulsi abu silika, NPK + ¾ emulsi abu silika, NPK + 1 emulsi abu silika, NPK + ¼ nano koloid silika, NPK + ½ nano koloid silika, NPK + ¾ nano koloid silika, serta NPK + 1 nano koloid silika. Hasil penelitian menunjukkan bahwa terdapat pengaruh pemberian pupuk silika organik terhadap serapan P, Si tanaman dan hasil hanjeli. Perlakuan NPK + 1 nano koloid silika memberikan Serapan P, Si tanaman serta hasil hanjeli tertinggi dengan nilai masing-masing sebesar 0,61 g/tanaman, 7,56 g/tanaman, dan 210,63 g/tanaman.Kata Kunci: Kulit biji hanjeli, Pupuk Silika Organik, Serapan dan Hasil Hanjeli
