Abstract

Production process flows are often the obstacles caused by production machine not functioning. Maintenance policies applied today are corrective maintenance and plan maintenance/time direct. Reliability centered maintenance (RCM) it’s method that can be used optimal maintenance action for every part of machine in galvanizing wire system. Steps above method planning consist of a functional block diagram (FBD), system function and function failure (SFFF), failure mode and effect analysis (FMEA), logic tree analysis (LTA), and task selection (TS). The results of analysis RCM method obtained 392 failure mode divided into 83 failure mode which is classified as critical and obtained 59 critical type part. Furthermore, the most appropriate maintenance action for 83 failure critical mode is 55 failure mode in condition directed (CD), 28 failure mode in failure finding (FF) category. Based on design of RCM, this research can reduce the frequency of machine breakdown on galvanizing wire system by 80.98%.

Abstract

Indonesia's consumption of energy increases significantly each year. While the reserves of energy are declining every year, alternative energy is needed. The waste treatment of rice husk biomass has been used for alternative energy, so the research aims to optimize the waste into fuel. The research site was conducted in Kelapa Dua Village, Jaya Subdistrict, Karawang Regency. To get the results of the design, there needs to be technological engineering to design production machines with the help of solidworks 2016 software. The research resulted in the form of compounding tools, as follow: Screw press diameter (Ds = 200 mm), screw height (hs = 65 mm), screw shaft diameter (dps = 70 mm), screw lift length (L = 420 mm), nominal screw diameter (Dn = 177.8 mm), screw lift width (Fd Max = 14 mm), screw spacing (pitch) (P = 60 mm), screw number (n = 7 threads), helix angle (β = 8), screw press power requirement (Pe = 119.27 watts), torque (T = 326.1 N.m), screw lift load (Ws = 141.5 N) and pressure developed on screw thread (PS = 1.65 N/mm2).

Abstract

One of the problems of lecture assignments based on drawing is drawing technique. The function of the learning software is to be the basic media of the teacher in explaining the material. This research aims to analyze the feasibility of learning software, namely computer aided design. Research techniques applied in this research are through reference sources from previous studies. The feasibility test method uses validity techniques that already have parameters in determining the feasibility of the test. Results from this study compared to the results of analysis from previous studies showed 78.6% (can be categorized as feasible). In addition, computer aided design learning software in 3D mini ragum has a validation result of 69% (can be categorized as feasible). Then it can be concluded that the learning software used today can support the delivery of materials that will be given.
