Abstract

Saat ini telah dikembangkan teknik pendinginan yang baru yaitu Minimum Quantity Lubrication (MQL), dimana 50-500 ml/jam lubricant disemprotkan ke arah sisi kontak antara pahat dengan benda kerja. Keberadaan lubricant sebagai pelumas dapat mengurangi gaya gesek antara pahat dengan benda kerja, sehingga umur pahat dapat diperpanjang. Pada penelitian ini akan dikembangkan teknik lubrikasi minimal yaitu dengan metode tetesan. Penelitian ini menggunakan empat metode pendinginan pahat yaitu: wet, dry, MQL, dan tetesan. Ester oil digunakan sebagai media lubrikasi pada penelitian ini. Pengujian menggunakan mesin Lathe CNC Denford Cyclone P, dengan insert carbide PLANSEE TIZIT DCMT 11T304 EN-SM. Nosel diarahkan pada sisi flank pahat bubut. Selama pembubutan dilakukan perekaman foto flank wear (VB). Pembubutan dilakukan hingga tercapai lebar flank wear 0.3 mm. Hasil dari pengujian ini menunjukkan teknik tetesan dapat meningkatkan umur pahat dan memperbaiki kekasaran permukaan benda kerja dibandingkan teknik wet ataupun dry. Teknik tetesan dalam hal umur pahat masih di bawah teknik MQL, tetapi teknik tetesan ini lebih sederhana jika dibanding teknik MQL, karena tidak memerlukan kompresor sebagai penyalur lubricant bertekanan.

Abstract

Ultra High Molecular Weight Polyethylene (UHMWPE) is a biomedical polymer applied for orthopedic as hip, knee, ankle and lumbar disc implants. The use of this material is common as a joint component paired with metallic biomaterials such as 316L stainless steel (SS 316L), cobalt chrome alloy (CoCr) dan titanium. This application has a wear problem. UHMWPE implants are commonly made with machining processes, i.e. lathe and milling. The effect of machining is the surface roughness of implant products. Polymer highly elastic in which would induce the deformation of surface asperities during loading and unloading. This phenomenon is determined with a parameter called elastic recovery. The magnitude of elastic recovery relates to the wear of the polymer. This research numerically investigated the effect of metallic biomaterial types on the UHMWPE elastic recoveries. Those metals are CoCr, SS 316L, and titanium. Two-dimensional surface asperity models were loaded with physiological gait loads of hip and knee. Results from computational works showed an insignificant difference of UHMWPE elastic recoveries penetrated by the studied metals. Elastic recovery due to SS 316L with knee gait load is 55.19%, equal to CoCr while other results due to titanium are slightly higher, 55.224%. The difference for all metals is only 0.06 %. Contact pressures are also equal, 38.96 MPa (CoCr), 38.98 MPa (316L and titanium).

Abstract

Currently, there is an outbreak of a new infectious disease in Indonesia, namely coronavirus disease 2019 (COVID-19). This disease is spread quickly through close contact and droplets expelled when coughing, sneezing, talking, or contacting contaminated surfaces. Some effective methods include always wearing a mask outside the house, maintaining a distance of at least 2 meters when interacting with people, and diligently washing hands with soap for at least 20 seconds. The community service program aimed to make portable and hygienic handwashing stations as a form of participation in preventing the spread of COVID-19 in the community. The station is easy to move, and users do not need totouch the faucet and soap dispenser. The user only needs to step on the foot pedal to open the faucet and soap dispenser. Viruses, bacteria, or germs can stick to the handle, and the touchless faucet will minimize contact. This station is expected to prevent the transmission of COVID-19. This community service program was carried out in Gunungkidul Regency, Special Region of Yogyakarta and supported by partners such as, Nglipar I, Ponjong, Tepus 1 and 2, Patuk 1 and 2, Semin 2, Panggang 1 dan 2, Gedangsari 2, and Girisubo Community Health Center. The distribution of the station ran smoothly, and it could be used properly. The Community Health Centers were helped with this program.

Abstract

UHMWPE (Ultra High Molecular Weight Polyethylene) is a unique polyethylene material widely used in biomedical applications as a bearing material for human body joint implants. The production of these UHMWPE implant components is still commonly performed with machine tools. Operation of these machines requires specific setting machining parameters in order to produce good UHMWPE surface quality without sacrificing the production cost. This research aims to find the relationship between cylindrical lathe machining productivity parameter, MRR (Material Removal Rate), and surface quality of the produced UHMWPE implant. MRR is directly related to production costs. The research was conducted by turning the UHMWPE at five feed rate variations between 0.025 to 0.2 mm/rev. and two depth of cut variations, 0.05 mm, and 0.1 mm, with a cutting speed of 150 m / minute. The test used a Denford FANUC CNC lathe machine with a cemented carbide cutting tool. Product quality was determined by measuring the topography or surface roughness of the material. Results show that the surface quality is inversely related to MRR. This problem can be solved by adjusting the depth of the cut. High productivity can be obtained by cutting thicker material. The difference in the surface quality of the cylindrical lathe machined material in the two depth of cut variations is not significant.

Abstract

The train is one of the main modes of transportation used in various countries in the world, including Indonesia. The existence of an efficient railway network can support the mobility of people and goods. The safety and comfort of train travel is highly dependent on the condition of the railway facilities and infrastructure. The condition of facilities and infrastructure that meet standards will make the journey smoother and reduce the risk of accidents. With human mobility, the development of public transportation using trains in Indonesia also continues to increase. Damage to train tracks can cause disruption to comfort and endanger safety caused by excessive vibration during train travel, so regular maintenance and repair of the rails is required using a system called the Intelligent Railway Vibration Monitoring System (IRV-MS). The IRV-MS system still needs to be tested because the resulting vibration readings still require validation. The design of this shaking rig simulator is expected to be a solution in terms of vibration testing. This shaking rig can move in a vertical or horizontal linear direction with a linear motor as a driver and produce oscillatory movements. The design of this shaking rig simulator tool uses Solidworks software with 500 mm x 423 mm x 380 mm of dimension and later vibration animation will be simulated in the motion study feature in the software with input parameters of 3-10 Hz with a maximum stroke of 20 mm.

Abstract

The management of organic waste into compost is one of the important solutions in an effort to reduce the negative impact of organic waste on the environment. A compost mixer is one of the technologies that can be used to speed up the process of decomposing and forming compost from organic waste. This research aims to continue previous research that has succeeded in making organic waste shredding machines. The methods used in this study include a literature survey on the basic principles in organic waste management, available technologies, and the design of stirring machine mechanisms that have been carried out previously. Based on the literature analysis, some factors in the design of the compost mixer machine are the material and shape of the composting blade, adequate construction strength, the need for sufficient rotation to achieve organic waste homogenization, and the ease of operation and maintenance. The design process utilizes CAD/CAE software to compile 3D models and simulate various operational conditions. The result of this research is the design of an efficient compost mixing machine mechanism. In addition, special attention is paid to the selection of materials and the shape of the stirring blades that are resistant to wear and corrosion. This design also takes into account the ease of access for routine cleaning and maintenance.
