Recycling organic of house waste remains fairly limited especially in urban area with low-and middle-income. A novel approach is developing method to manage the organic waste conversion using larvae Black Soldier Fly (BSF). The advantage of this approach links to the green technology waste management which is no pollutant effect to the environment as well as increase the added value economically. The research project successfully presented organic house waste conversion into high protein of animal feeding source. From the 5 dol of larva BSF’s (approximately 17 gr), it was reduced organic waste ± 0.7 kg/day. Within 10 days, the larva BSFs of 17 dol was consumed organic waste ± 10 kg, with increase their weight to become approximately 10 kg. The larva BSF of 17 dol is potential as animal feeding source that contain a high of protein. Furthermore, the waste from BSF’s cycle life is potentially to convert into chitosan, due to contain of chitin. Chitosan was produced from the waste of larvae skin, pupa skin and insect imago death. In general, this organic waste management is offering to green organic waste management in the future.

The depletion of sulfide nickel ore and the growing of stainless steel demand each year cause the use of low-grade laterite nickel ore continues to increase. Due to very low nickel content, there is no optimal process to extract them. One of the alternative processes being developed now is the sintering-blast furnace process which produces Nickel Pig Iron (NPI). This research was conducted by sintering limonitic laterite nickel ore using charcoal as fuel and limestone as a flux. This research aims to analyze the effect of charcoal mass variation on Ni content, sinter strength, and the yield on the sintering process of limonitic laterite nickel ore. Charcoal and limestone demand calculated using energy balance and mass balance, then varied charcoal mass to feed material. Feed materials are fed in the furnace, heated at a temperature of 1200oC with 4 hours holding time. Next, the sinter yield was calculated. EDX, XRD, and Drop tests were also performed to determine Ni content, sinter compounds, and strength. The highest Ni content was 3.66% which was obtained by adding 9.9 kg charcoal. The highest sinter strength and yield also obtained by adding 9.9 kg charcoal (72.30% and 86.44%, respectively). Mayor phases which formed on sinter with 9.9 kg charcoal addition is nickel-iron oxide.
