Abstract

Coffee beans in Jember Regency continue to be increased in line with the expansion of new crop fields. New coffee plantations plus 9 hectares were based on data from the Jember Regency Statistics Agency from 2008. Coffee bean production in Jember District in 2011 totaled 28,961.79 quintals, from 22,080.47 quintals for 2010. (Budiharjo, 2014). The increase in coffee bean production and land area is not followed by the level of prosperity of coffee farmers who own the land (Budiharjo, 2014). An appropriate technology to increase the selling value of coffee products  are roasting and packaging. The roasting method used greatly affects the quality of coffee. This study focused on the variation of insulators applied to roasting machines. The purpose of this study was to determine the rate of heat loss from the coffee roaster machine after being given the addition of an insulator and find out how much coffee production costs using a roaster machine which was given the addition of an insulator. Experimental research using a coffee roaster machine with LPG fuel with a capacity of 10 kg. Research was carried out by varying the insulators used such as without insulators, adding aluminum foil, adding glass wool, adding wood powder, adding glass wool and extruded polystrene foam, the last addition wood powder and extruded polystrene foam. Data retrieval was carried out using a temperature sensor and data logger with four thermocouple types K mak 6675. In addition to data retrieval of temperature, LPG consumption data was also collected. The results showed that the smaller thermal conductivity of an insulating material, produced lower  heat ratio and  lower  fuel consumption.

Abstract

In a power plant unit whose main fuel is coal, there is generally use a belt conveyor installation. This conveyor belt serves to supply coal from the crusher unit to the combustion chamber of the power generation unit. In this study, we discuss a case where the installation of a belt conveyor which was initially only one line was then made a new branch that supplies coal to other power generating units. Equitable capacity distribution and continuity of coal distribution are the main focus of this study. Therefore, a design of automatic control system of coal flow divider on belt conveyor installation was designed. The working principle of this coal flow splitting system is to control the movement of the straight blade plough that directs the flow of coal to each unit at the certain time and continuously. Straight blade plough in the form of steel metal plate with a thickness of about 10 millimeters in which one end is connected to the end of the pneumatic cylinder. Automatic control system of coal flow divider in belt conveyor installation designed using CX-Programmer and CX-Designer applications. CX-Programmer serves to create automatic control logic concepts. While the CX-designer functions to create a Human Machine Interface (HMI), making it easier for operators to control the course of the coal supply process. The results of this study are in the form of control logic lines that can be applied to Programmable Logic Control (PLC) device and Human Machine Interface (HMI) equipment.

Abstract

A wind turbine is a device that converts wind energy into mechanical energy to produce electric power. Wind turbines have a simple working principle, which is to convert wind energy into mechanical energy in the windmill, then the rotation of the turbine0makes the rotor on the generator rotate and generate electricity. There are 2 types of wind turbines: vertical axis wind turbine and horizontal axis wind turbine. This study aims to determine the performance of the medium-scale VAWT hybrid savonius darrieus NACA 4712 wind turbine. The hybrid wind turbine is a combination of savonius and darrieus wind turbines to increase efficiency by utilizing the drag of the savonius turbine and lift force from the darrieus wind turbine. This study used an experimental method. The fan is used to vary the wind speed. The wind speed used ranges from 5, 5.5, 6, 6.5, 7, 7.1,7.2,7.3 m/s. This savonius darrieus hybrid wind turbine can produce efficiency of 0.037 at wind speed of 5 m/s with an initial torque of 0.088 N/m. The maximum rotation in this hybrid turbine study 118 Rpm was obtained at a wind speed of 7.3 m/s.

Abstract

The manufacturing industry has grown rapidly in the last few decades. 3D printing is one of the technologies of manufacturing, this technology makes products by adding filaments that are stacked systematically to become a finished product. PETG filament is a polymer with the name polyester but with glycol modification. This study aims to determine and understand the effect of the process parameters layer height, nozzle temperature, infill geometry and printing speed. This research method uses the Taguchi method with L16 and various parameters; layer height 0.12mm; 0.16mm; 0.2mm; 0.28mm, infill geometry cross; cubic; tri-hexagonal; triangles, nozzle temperature 220ºC; 230ºC; 240ºC; 250ºC and printing speed 40mm/s; 50mm/s; 60mm/s; 70mm/s. After testing, it can be concluded that the most influential parameters are sequentially; layer height, nozzle temperature, printing speed, and infill geometry with layer height parameters have the dominant influence, nozzle temperature and printing speed parameters have a balanced influence and infill geometry parameters have the least influence.

Abstract

This study discusses the design of a car rim and analyzed its mechanical properties using three different basic materials: aluminum, steel, titanium. The purpose of this study is to reduce production time and to minimize the risk of design failure. In this study using the Catia software to design a rim, then simulate the effect of applying force on a component, applying a certain working pressure, then able to perform calculations and display the results for analysis. The analytical method used is the FEM method of static analysis. The mesh type uses a linear tetrahedron mesh. Provision of clamps or fixed constraints is carried out on the surface of the bolt hole, where this surface is in contact with the wheel holder of car drive system. Then given a circumferential loading of 200 kN/m2. It was found that aluminum material is the best for the manufacture of car rims, which has a low density so it is lighter than steel and titanium. However, alloys such as lead and magnesium are needed to increase their hardness, and chromium alloys are needed to protect the rims from corrosion due to use in a polluted environment and contain impurities that can trigger corrosion.

Abstract

This research is aimed to provide insight on the dependency of tensile strength on process parameters of the Fused Deposition Modeling (FDM). FDM is one of the most popular 3D printing manufacturing techniques. In the present study, a tensile test was performed to measure the tensile strength of PETG (Polyethylene terephthalate glycol) specimen with the combination of different layer height, infill geometry, nozzle temperature, and fan speed whereas other parameters are kept at a constant level. This study uses the ISO 527 1BA standard. Taguchi L16 (44) with 4 levels for each factor was used to determine the effect of each parameter. Each experiment repeated 3 times to minimize the occurrence of errors. layer height, infill geometry, nozzle temperature, and fan speed ​​respectively effect of 13.4%, 63.6%, 19.0%, and 2.7%. Fan speed is considered a parameter that has no impact on tensile strength. The layer height and nozzle temperature parameter shows that the higher the value, the tensile strength of specimens tend to increase. Furthermore, infill geometry from the one with the highest to the lowest tensile strength value is gyroid, zig-zag, grid, and triangles. The combination of layer height of 0.24 mm, infill geometry gyroid, and nozzle temperature of 250 ˚C is the optimum combination of parameters which has the highest tensile strength of 34.76 N/mm2.
