<![CDATA[Optimization design of multifunctional machines for making of animal feed is one of the development efforts of conventional machinery to be a multifunctional machine with electric motor drive which is to help small MSME industries so that their results and capacity are faster and more effective during the process of milling and grinding. This is a new concept designed to increase the time effectiveness of its use. This tool is specifically designed to chop odot grass and grind corn kernels, where the tool works using resources from an electric motor that moves a U-type blade or type I blade for knitting or grinding. The method used to make multifunction machines includes the development of existing models, seeking research on previous tools, refining the design model concept, making 3D models using the Solidworks Computer Aided Design (CAD) with a cycle time of 50 seconds on different test pieces and mills where assembly time is needed to complete the multifunction machine for ± 20 days or 28800 minutes.]]>

<![CDATA[The initial activity in this study was carried out by examining the results of testing of reinforcing steel through tensile testing and bending testing. The study focused on the stress analysis of the test material to determine and classify the test material with SNI reference which applies as a condition for the application of test material to a construction. The material tested was a type of Fin Reinforcing Steel (BjTS 40) with diameters of 10 mm, 13 mm, 16 mm, 19 mm and 22 mm respectively with each sample 2 specimens. In tensile and bending tests, the test results will be known the load of the test material when tested at the yield point and at the maximum point, according to the strain stress graph illustrated. The results of the scale of the test machine are then recorded to perform stress analysis. The test results data are then used to calculate the amount of stress that occurs in the test material. Stess analysis is carried out on the swing hanger as well as construction steel samples. Stress analysis uses theoretical stress analysis methods and finite element simulation methods using computer work program simulation CAD / CAE technology solidworks. From the results of theoretical calculations, it is known that the amount of stress that occurs, the yield strength limit of the material and also the safety factor of the test material, both on the swing hanger test material and also the construction steel test sample. Furthermore, the initial data of the swing hanger test material as well as steel construction were carried out modeling by using a solidworks computer work program application. While the results of solidwork modeling are then analyzed by finite element simulation and known the magnitude of stress, strain, loading buckling that occurs and also the visualization of the material characteristics of the load treatment.]]>

<![CDATA[Di Indonesia sebagai negara agraris mempunyai banyak sumber bahan baku, salah satunya adalah beras ketan putih (Oryza sativa L. var glutinosa) yang terdapat cukup banyak. Beras ketan putih merupakan salah satu makanan yang disukai oleh masyarakat. Selain itu, banyak pengolahan makanan yang berbahan dasar ketan seperti Uli. Seiring dengan perkembangan, maka dari itu dirancang Mesin Penumbuk ketan dengan kapasitas 40 kg/jam dengan menggunakan sistem pneumatik. Metode yang digunakan dalam kajian ini, yaitu dengan mengumpulkan beberapa studi literatur dan analisa, kemudian melakukan perencanaan desain serta perhitungan, analisa (safety of factor) dengan menggunakan software SolidWorks dan menentukan serta memperhitungkan komponen-komponen yang digunakan dengan merealisasikan suatu konsep desain yang sudah dirancang, sehingga mempermudah melakukan pengujian eksperimen. Maka dari itu dirancang mesin penumbuk ketan dengan kapasitas 40 kg/jam untuk meningkatkan efisiensi waktu dalam proses pengerjaann atau penumbukan. Silinder Pneumatik pada sistem ini digunakan untuk menggerakan penumbuk. Dalam pembuatan alat dengan sistem pneumatik ini, digunakan kompresor dengan spesifikasi tekanan 793 kPa, power 1,5 KW. Jika dikerjakan secara manual membutuhkan waktu 1 jam untuk menumbuk ketan dengan kapasitas 0,002 Kg atau sekitar 2 liter.

<![CDATA[Judul: Pengembangan sistem pemantauan getaran untuk model mesin berputar menggunakan fast fourier transformTitle: Development of a vibration monitoring system for rotating machine models using fast Fourier transformSering kali terjadi kerusakan mekanis pada mesin silinder berputar . Kerusakan itu terjadi akibat dari getaran yang terjadi pada mesin-mesin berputar. Penyebab getaran pada mesin berputar antara lain disebabkan oleh beberapa hal di antaranya: ketidakseimbangan, tidak sejajar, dan bagian yang tidak sempurna atau cacat pada komponen mesin. Penelitian ini mencoba untuk memberikan solusi dengan cara pendekatan analitik menggunakan sistem pemantau getaran. Sistem tersebut bisa memberikan manfaat dalam proses deteksi, memvisualisasi getaran dalam bentuk grafis, menemukan magnitudo yang merupakan puncak getaran dan menghitung frekuensi getarnya. Pada penelitian ini dikembangkan prototipe alat pemantau getaran dengan melengkapi komponen Load cell sebagai sensor getar, arduino atmega 2560 untuk sistem kontrol, dan mengimplementasikan fast fourier transform.The spinning cylinder engine is often damaged mechanically. Vibrations in spinning machinery cause damage. The reasons for vibration in rotating machines include imbalance, misalignment, and faulty parts or faults in machine components. This research attempts to offer a solution by using an analytical method and a vibration monitoring system. The system may help with the detection process, displaying vibrations in graphic form, determining the amplitude and peak of the vibration, and computing the vibration frequency. In this research, a prototype of a vibration monitoring device was created by completing the load cell component as a vibration sensor, Arduino Atmega 2560 for the control system, and applying fast fourier transform.]]>

<![CDATA[The industrial sector is currently increasingly competitive and intensively developed through increasingly sophisticated technology. One of the factors supporting the effectiveness and efficiency of production is the engine, so that engine performance needs to be maximized. PT. Nirwana Internar Jaya is a company engaged in the manufacture of pipes using a twin screw extruder machine. The machine does production continuously, so it does not rule out the possibility of downtime. This study aims to determine the optimal maintenance action and determine the maintenance time interval on the twin screw extruder machine using the Reliability Centered Maintenance (RCM) method. The results obtained are that it can reduce the downtime of the twin screw extruder machine from 72.5 hours to 27.5 hours by performing maintenance on heating control system components with maintenance time intervals of 155.15 hours or 7 days, motor cooling fan 739.02 hours or 31 days and blower/fan components with maintenance intervals of 828.08 hours or 35 days. Condition monitoring measures also need to be taken to reduce disturbances that can hinder production activities.]]>

<![CDATA[The hydraulic system has been widely used for various tools. The system developed from Pascal's law becomes one of the vital knowledge that its use in the industrial world. Ranging from small businesses to some kind of a car wash with large industries such as molding machine. The components are arranged in the hydraulic cylinder includes a tube, piston, rod axles, gland, and seal. Each component has the function and role of each and every component seal types are also different types, for a material component of the hydraulic cylinder must not rustproof for hydraulic oil in addition to the driving also serves to lubricate the hydraulic cylinder components. The greater the pressure in the hydraulic tube is getting thicker the hydraulic tube wall, so that the seal does not leak type of profile and material must be in accordance with the state of the hydraulic cylinder, for the connection technique in the hydraulic cylinder components should also be considered such as when welding, welding wire material must be in accordance with the material to be welded. For the methods used in the design of the hydraulic cylinder on the rubber molding machine is an analytical method burdened straight column in the center of axle rodmethods MAWP (Maximum Allowable Working Pressure) to force the tube The results of this design is for a straight column burden in the short-sized center, and to the strength of the tube can withstand the pressure 607.74 bar as well as the costs required to make the hydraulic cylinders in rubber molding machine is very affordable.]]>
