“…Tensile strength is the test used to determine how much force that sample can withstand until it breaks, while elongation test to find out the elongation created on the sample from the initial condition to broken off (Safitri et al, 2016& Suparno et al, 2013. Both of tests using universal testing machine with a speed of 10 mm/min (Rosid et al, 2019). Moreover, biodegradation test is the test to determine level of degradation by looking at the percentage loss of sample mass (Rahmawati, 2018).…”

This study aims to determine the effect of enhancement in stirring temperature (75oC, 80oC, 85oC) and type of plasticizer (glycerol and sorbitol) on the characteristics of biodegradable straw from ambon banana peel waste and to compare them with the characteristics of conventional boba’s straws. Methods used in this study were tensile strength, elongation, biodegradation, and water uptake tests. The result showed enhancement of stirring temperature and type of plasticizer did not significantly affect the characteristics of biodegradable straws from ambon banana peel waste (p > 0.05). Enhancement of stirring temperature will increase the tensile strength and water resistance value, but decreased elongation and biodegradation value because enhancement of stirring temperature will decrease the water content and increase the molecular density. In addition, plasticizer will increase elongation value and level of biodegradation, but decrease tensile strength and water resistance values. Plasticizer has the ability to increase the elasticity of polymers, as well as increase water absorption because it has hydrophilic hydroxyl groups. Biodegradable straw that have been developed has a colour of black, being rigid, with a length of 13 cm and an external diameter of 1.2 cm. The colour and external diameter of biodegradable boba’s straw looks similar with conventional boba’s straw but shorter in length. Therefore, ambon banana peel waste was promising to be used as an alternative material for biodegradable straw in the future.

“…3D Printer FDM dapat dimodifikasi untuk mencetak material biokomposit berbentuk pasta biokomposit (Tontowi, Anggraeni, Saragih, Raharjo, & Utami, 2017) . Sedangkan properti mekanik dari material tersebut sebesar 3,337 Mpa untuk uji tarik dan kemampuan tekan sebesar 2,653 Mpa (Rosid, Putra, & Tontowi, 2019). material tersebut dapat keluar melalui nozzle 3D Printer namun tidak secara secara kontinu, hal tersebut dikarenakan proses curing terjadi lebih cepat, sehingga menyebabkan material lebih cepat mengeras (fase solid) ketika material masih dalam proses ekstruksi di dalam chamber.…”

Bone fracture caused by various incident causes medical problems. Then bone restoration is required. Bone grafts can be used to solve this problem. One of the materials that can be used to produce bone graft is PMMA. PMMA requires to be combined with other materials to extend the solidification time. The material that can be used for bone graft material is sago starch. The main ingredient composition of Biocomposite [sago/PMMA] consists of sago: PMMA = 1 : 1 (w/w). The composition of the addition of MMA is 10% (v/w) of PMMA, this is to extend the curing time. Thus the material can be through from the chamber extruder to the nozzle. This research aims to obtain combinations of 3D Printer FDM Customized machine parameters for minimizing of error dimension. The 3D Printer machine uses pneumatic system to push the material from the container to the chamber and used screw extruder to push the material out through the nozzle. The experimental design method used a 2 k fractional factorial design, with 3 parameters, 2 levels and 3 responses. The experimental results obtained that the layer height parameter has a significant influence on the x-dimensional error. The optimization results obtained a combination of parameters to get the smallest error dimensions, the print speed is 25 mm/s, the layer height is 2.93 mm and the fill density is 20%. The results of optimization obtained that the x-dimensional error is 0.016, the ydimensional error is 0.069 and the z-dimensional error is 0.4539.
