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.

Abstractresearch in the field of biomechanics related to orthopedic implants is rapidly growing in the world, especially for fixation of fractured bone. Fixation is a surgery to locate and attach a plate pressed by screws at the fractured bone. Most of the fracture bones sited in femur. This research focuses on modeling and simulation of plate and screw made of SS316L material for the fixation of the fractured femur using finite element method (FEM). SS316L is a material with good biocompatibility, cheap, and ductile enough. Modeling and simulation done using ANSYS 15.0 software. Simulation results are stress, strain, and total deformation. It is obtained that optimum diameter of screw is 4.5 mm with respect to minimum value of von Mises stress and deformation.Keywordsdeformation, finite element method, screw diameter, SS316L, von Mises stress.

NiTi is alloy that has unique properties include shape memory dan superelasticity. However, it has disadvantages which cause allergic and toxicity to the body from the Ni release. In order to reduce Ni release and increase corrosion resistance an Electropolishing Pretreatment-Photoelectrocatalytic Oxidation (EP-PEO) and Advanced Oxidation Process (AOP) coating were synthesized in order to produce TiO2. Scanning Electron Microscope (SEM) was depicted various morphologies of NiTi orthodontic wire surface. Ni release experiment in various saliva by using Inductively Coupled Plasma (ICP) was shown reducing Ni release significantly both in saliva pH 3 dan pH 6.25 in AOP coating for 2 months monitoring. This results confirmed that the Ni release was evidently decreased and the corrosion resistance significantly improved after coated with AOP.
