Packaging material’s demand continue to increase along with the development of industry all over the world. Styrofoam as conventional packaging materials, have been looked for a subtitute because it does not decompose and the depletion of fossil fuels as it’s feedstock. Cornstalk has abundant amount as biomass waste. Despite it’s well known quality as raw material for pulp, it hasn’t got utilized yet. Molded pulp as one of the alternative packaging, has a promising future with it’s degradable characteristics and good mechanical properties. Cornstalk as raw material for the pulp along with the empty fruit bunch (EFB) ash works as the alkaline source for the alkaline pulping. The binderless molded pulp then formed with the help of hot press. The thermoset properties of the lignin itself, give the posibility to produce molded pulp without any binder resin. Tensile index, tear index and burst index were determined experimentally to express the mechanical properties of the binderless molded pulp products. This experiment were done as an effort to utilize the biorenewable resource to make a packaging product that could be an alternative to the conventional one.The result indicate that cornstalk as raw material to produce molded pulp gives good mechanical properties compare to styrofoam packaging product. Molded pulp from cornstalk gives tensile index 17,5 – 34 Nm/g, tear index 10 – 26 mN.m2/g and burst index 0,89 – 1,52 kPa.m2/g. In generally, variation of temperature give dominant significant influence to mechanical properties of molded pulp.Keywords: Binderless; Cornstalk; EFB Ash; Packaging; Molded Pulp

The aluminum and its alloy have several characteristics i.e. relatively low density, high electrical and thermal conductivity and also good in corrosion resitance. The molding process of green anode blocks at an aluminum plant is carried out by an anode forming system. In this system, there is a printer called as turntable vibrating compactor or referred to as a ‘shaking machine’. During 55 seconds of anode block compaction, the fluctuating stress would be received by hydraulic cylinder bolt due to vibrations of the turntable vibrating compactor. Fluctuating stress that works continuously on the bolt can increase the tendency of failure. This paper aims to find out the causing factors and alternative solution for failure of the hydraulic cylinder bolt. To determine the cause of failure, several methods are carried out, i.e. fractography investigation, metallography examination according to ASTM E3-95, hardness testing according to ASTM E92-17 and tensile testing according to ASTM E8/E8M-16a. Fractography investigation show the failure mode of low cycle fatigue due to the application of high nominal stress. This is indicated by the presence of ratchet, beach mark, river mark and shear lip. The short life of the bolt due to the hardness and strength of the bolt after undergoing the heat treatment process Q + T cannot increase its endurance limit.

To upgrade aerial vehicle of Atha Mapper 2150 capable of vertical take-off and landing capability, it needs to be integrated to the tricopter vehicle. In this study the tricopter frame structure was designed based on the Atha Mapper 2150 fixed wing vehicle. This study began with a calculation process to determine the dimensions of the tricopter.. Next, the process of building four tricopter concept designs with variations of the shape of the frame and the cross section of the arm. The four concept designs are selected using a decision matrix. Based on the values in decision matrix table, the design concept I (Y configuration and rectangular arm cross section) was the best design, because it has the highest weighting value. The selected design was then simulated for its structural strength in Ansys software by giving a load of thrust to the three arms of the tricopter frame. In the middle of frame is given a boundary condition in the form of hinges. From the static simulation results of the tricopter frame structure, the maximum stress value was 54,126 MPa, which occurred on the M3 arm. The greatest total deformation also occurred in the M3 arm with a value of 10,335 mm. The safety factor value of tricopter frame structure was 8.77. This shows the tricopter frame structure with the main material in the form of carbon fiber, acrylic and PLA meets the required safety criteria.

Various attempts have been made to substitute metal as the wax pattern mold material due to manufacturing costs and time-consumption. This research investigates the linear and volume shrinkage on the wax pattern of gypsum, silicone rubber, and epoxy resin as alternative materials to metal molds. A nylon master pattern was made by machining. The master pattern size was set as a reference for dimensional comparison with the cast wax pattern. Wax pattern molds were created using the master pattern, namely gypsum, silicone rubber, and epoxy resin. Paraffin wax was heated up to 55˚C in metal, then poured into each wax pattern mold. The length, radius, inlet, and outlet diameter were measured using a profile projector, then the linear shrinkage was calculated. The volume shrinkage was obtained through the sample weighing. The results show that silicone rubber has the lowest linear shrinkage of any sample in contrast to its volume shrinkage.
