Abstract

Industri otomotif dan manufaktur khususnya sepeda motor dituntut untuk terus berkembang, misalnya dengan penggantian jenis material untuk komponen tertentu agar lebih ekonomis namun tetap memenuhi fungsi. Sebagai contoh perubahan material yang sebelumnya dibuat dari baja cor menjadi aluminium cor untuk komponen steering stem atau biasa disebut dudukan segitiga pada sepeda motor. Kajian ini bertujuan mengkaji apakah perubahan material steering stem dari baja cor SC450 ke aluminium cor AC4CH tetap aman untuk diaplikasikan pada sepeda motor jenis skuter matik (skutik). Dalam pelaksanaannya dilakukan simulasi pembebanan statis dari berat kendaraan ditambah penumpang dan beban impak disaat kendaraan melaju dengan kecepatan 40 km/jam. Analisis menggunakan metode elemen hingga dengan perangkat lunak Ansys. Hasil analisis menunjukan nilai defleksi tertinggi untuk material AC4CH sebesar 0,17 mm, sedangkan pada material SC450 sebesar 0,11 mm. Ada pun tegangan maksimum yang terjadi untuk AC4CH sebesar 181 MPa masih di bawah kekuatan material 250 MPa. Untuk material SC450, tegangan maksimum yang terjadi 233 MPa, masih di bawah kekuatan material 450 MPa. Dari hasil ini menunjukkan bahwa meskipun kekuatan aluminium cor AC4CH lebih rendah dari pada baja cor SC450, namun AC4CH masih aman untuk diaplikasikan sebagai meterial steering stem skutik dengan keuntungan bobotnya lebih ringan.

Abstract

Penelitian ini dilakukan untuk mengetahui karakteristik dan sensitivitas dari transduser gaya jenis Extended Octagonal Ring (EOR). Analisis dibagi menjadi dua yaitu menggunakan metode elemen hingga dan pengujian eksperimental. Sensitivitas EOR ditentukan melalui pengujian eksperimental dengan pembebanan vertikal 100 N hingga 500 N. Analisis metode elemen hingga menggunakan software ANSYS dengan pembebanan 3 kN hingga 15 kN disesuaikan dengan beban kritis buckling. Hasil pengujian menunjukan linearitas dan sensitivitas silang pada EOR. Pengujian eksperimental diperoleh sensitivitas EOR diperoleh sebesar Kv = 0.1999 μs.N-1 untuk gaya vertikal dan Kh = 0.0056 μs.N-1 untuk gaya horizontal dengan sensitivitas silang sebesar 2.8 %. Analisis metode elemen hingga diperoleh sensitivitas EOR diperoleh sebesar Kv = 0.1858 μs.N-1 untuk gaya vertikal, Kh = 0.0018 μs.N-1 untuk gaya horizontal dan Km = 0.007 μs.N-1 untuk momen dengan sensitivitas silang sebesar 0.9 % dan 3.76 %. Selanjutnya, EOR dapat digunakan sebagai transduser untuk analisis buckling.

Abstract

Abstract: A prototype of homemade furnace was built and the highest temperature it can reach during the trial process is approximately 400OC. Beside liquid metal, the furnace also produced exhaust gas as a side product. The exhaust gas is still hot. Hot gas can be used to improve the furnace’s temperature based on blast furnace method. To apply this method, the furnace should be companied with cowper. In designing cowper, several parameters should be notice. The parameters are hot gas temperature, air flow direction, and its movement ability with the furnace. Hot gas temperature will determine the number of heat absorber layers. The direction of the air flow will determine the cowper construction. Movement ability is associated with space. The design is made based on VDI 2221. The cowper design concept is cowper to store hot gas made of ramming refectories with its outer diameter similar to oil tank and the movement mechanism only applied for migration.

Abstract

The implementation of this Community Service program is part of the activities of the Production Systems Laboratory of the Industrial Engineering Department, FTI Trisakti University, as an effort to share knowledge in industrial society. PT TIJ is a women's bag company located on Jl. Raya Bogor km.38 No.1 Cilodong - Depok. grow with family management. Companies need knowledge sharing in order to increase efficiency and company performance for plans to increase bag production capacity. Community service activities in the form of counseling and mentoring activities to industrial community, namely employees of the PT TIJ bag company. Based on interviews and observations, it can be seen that there are inefficiency problems in production process activities, plans to increase production capacity and the need for finished product warehouse layout design..Counseling activities are carried out using zoom media followed by visits to companies to provide consultations in the context of assisting companies to understand the utilization of Industrial Engineering knowledge, namely Lean Production to improve company performance. PkM activities at PT TIJ with the topic of Utilizing Lean Production include material: Lean Production Systems, Facility Layout Design, Time Study and Movement Study as well as Machine Maintenance material which has been carried out well, it is hoped that this can reduce the inefficiencies that occur thereby improving the performance of the company's manufacturing system.

Abstract

The suspension system on Heavy Dump (HD) vehicles is crucial in maintaining stability, comfort, and reliability when used in harsh environments. HD vehicles have a hydraulic-pneumatic suspension that uses nitrogen gas and oil to overcome the load and vibrations from the road. The suspension maintains vehicle components and protects the load, especially when crossing damaged or bumpy roads at high speed. This study aims to optimize preventive maintenance planning using the Reliability-Centered Maintenance (RCM) method and determine the suspension system's preventive activities to reduce breakdowns. In designing effective preventive maintenance, the RCM approach and related methods, such as FMEA, are used to identify critical machines as the focus of analysis. In addition, a statistical distribution approach is used to determine the optimal maintenance activity interval. Based on the analysis results, it was obtained that the data follows a lognormal distribution where the optimization of preventive maintenance on the suspension component is every 370-hour time interval for each machine working. Changing the time interval increased the reliability value from 34.09% to 93.60% before and after preventive maintenance. Preventive maintenance activities with a time interval of 370 hours to reduce unscheduled breakdowns in the form of adjusting suspension components
