【 摘 要 】

The potentials of corn silk in terms of its physicochemical properties and its heating value have been investigated. The sample was originated from Badas village, district of Kediri, East Java, Indonesia. The original material underwent a drying process in the oven at 100 °C for 90 minutes. The dry materials were continuously pulverized and filtered to reach the mesh size of 60. Subsequently, the sample was tested according to the proximate standard to specify its physical properties, while its elemental composition was investigated under the energydispersive X-ray (EDX) spectrometry procedure. The results showed that corn silk contains the moisture, volatile matter, fixed carbon, and ash in respective value, i.e., 8.6 (wt%, as received), 72.2, 22.4, and 5.4 (wt%, dry basis). The EDX test showed that C and O present as the dominant element. The gross calorific value assessed by using adiabatic bomb calorimeter was 19.50 MJ/kg.
