Abstract

Braking system is an important thing on safety of the train. In that process, kynetic energy  changed into thermal energy that would be known by the increasing of temperature at the surface and around the area of contact between the wheels and brakes. From research before, the increasing of contact temperature would lead a thermal crack on the wheel. Failure could be occure by that crack. Based on that results, research on the phenomenon of rising temperatures due to friction between wheel and railwould be very needed. In this paper,the effect of temperature and relative velocity of the surface to coefficient of friction would be studied. Experimental study of this paper using pin on disc test with 2 kg load and relative velocity variated from 4,61 m/s(400 rpm); 5,76 m/s(500 rpm) and 6,91 m/s(600 rpm).Results of this research shows that increasing temperature and relative velocity would lead an increasing of friction coefficient. Key word: brake, composite, temperature, friction coefficient, relative velocity

Abstract

ABSTRAKFiberglass lebih ekonomis dibandingkan dengan kayu maupun logam untuk bahan pembuatan kapal yang berukuran kecil. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pengetahuan tentang design kapal dan bahan pembuatan kapal berupa Fiberglass Reinforced Plastics (FRP). Pengetahuan tentang design kapal, dan pengetahuan bahan Fiberglass Reinforced Plastics (FRP) dianggap penting karena masih kurangnya pengetahuan akan hal tersebut. Pembuatan kapal berbahan fiberglass secara tidak tepat dapat mengakibatkan pengendalian kapal yang kurang maksimal. Selain itu, kekuatan lambung kapal juga tidak sesuai dengan standard. Kegiatan pengabdian ini dilakukan dengan dua tahap yaitu pelatihan dan pendampingan pembuatan kapal berbahan fiberglass. Dari hasil evaluasi didapatkan bahwa peserta memiliki keterampilan teknik hand lay-up dan pengetahuan bahan yang baik setelah diadakannya pelatihan dan pendampingan. Kata kunci: kapal; fiberglass; hand lay-up; nelayan; pariwisata; mangrove ABSTRACTFiberglass is more economical than wood or metal for small shipbuilding materials. This community service activity aims to provide knowledge about ship design and shipbuilding materials in the form of Fiberglass Reinforced Plastics (FRP). Knowledge of ship design, and knowledge of Fiberglass Reinforced Plastics (FRP) is considered important because there is still a lack of knowledge about it. Making boats made of Fiberglass improperly can result in less than optimal ship control. In addition, the hull of the ship is also not up to standard. This service activity is carried out in two stages, namely training and mentoring in the manufacture of Fiberglass boats. From the evaluation results, it was found that of the participants had good hand lay-up technique skills and material knowledge after the training and mentoring. Keywords: boat; fiberglass; hand lay-up; fisherman; tourism; mangrove

Abstract

The development of fishing and marine tourism requires the support of naval architecture, especially in small boat. The use of wood as the main material for shipbuilding has recently become a problem considering the decreasing availability of wood, while the use of fiber is classified as less environmentally friendly because it uses chemical resin and difficult to repair when it breaks and cannot be recycled. The aim of this research is to design the High-Density Polyethylene (HDPE) boat. The design was carried out by using naval architect design software. The stability of boat was calculated by using three loading conditions such as when leaving the port, in the sea and when returning to the port. The International Maritime Organization (IMO) safety criteria was using to evaluation of boat stability where the three loading conditions have met the IMO standard. The construction of HDPE boat was carried out by using DNV rules.

Abstract

Geothermal energy is a renewable alternative energy source. One of the analyses used to determine the characteristics of a geothermal field is water geochemical analysis. The target of this research is the Blawan-Ijen geothermal prospect area, Bondowoso. The geochemical analysis was carried out using AAS, Spectrophotometer and acid-base titration. This survey shows the characteristics of the geothermal system and geothermal fluid in the Blawan area, Ijen. From the chemical analysis of hot water, we found that the types of geothermal water fluids in the Blawan Ijen area vary. In samples BL1, BL2 and BL5 included in the type of Sulphate Water with the dominant elemental Sulphate (SO4) content is also known as Sulfuric Acid Water (Acid-Sulphate Water). Then for the BL4 sample included in the type of chloride water. This type of water is a type of geothermal fluid found in most areas with high-temperature systems. Areas with large-scale hot springs flowing with high Cl concentrations originate from deep reservoirs and indicate permeable zones in those areas. However, this area may not be located above the main upflow zone. There are several other possibilities, such as topographic influences, which can significantly impact hydrological control. The presence of chlorine gas can also identify high zones' permeable areas (e.g., faults, breccia eruptions or conduit). In contrast, BL3 samples are included in the Bicarbonate Water-type. The element HCO3 (bicarbonate) is the most dominant element (main anion) and contains CO2 gas from the chemical analysis results. HCO3 water is generally formed in marginal and near-surface areas in systems dominated by volcanic rocks, where CO2 gas and condensed water vapour into groundwater. The vapour condensation can either heat the groundwater or be heated by steam (steam heated) to form an HCO3 solution

Abstract

The national energy demand, especially the oil and gas sector, is increasing in line with the increasing population and the condition of national economic growth which continues move positively. The increase of energy demand is on average more than 5% per year for this decade. Meanwhile, the condition of national oil and gas reserves and production sector continues to decline every year. This has resulted in Indonesia becoming a net importer of oil and gas. Domestic demand for natural gas increases every year, while on the other hand Indonesia still has commitments to sell natural gas abroad, pipeline gas and LNG. For this reason, a more accurate prediction of natural gas in Indonesia will be very helpful for policy makers so that policies taken are right on target so that natural gas which should be consumed domestically is not exported abroad. One of the good prediction methods is using artificial neural network (ANN). In this study, the input data used are economic growth, population, and gas prices, while the output data is natural gas consumption. This study uses five ANN architectural models that are formed. From the simulation results, the best accuracy is model 1 with an accuracy of 96.89%.

Abstract

   Measuring the forces that work during machining has been being concerned by researchers for years. There are three main forces that work in turning: thrust  force, axial force, and radial force. Thus, feeding force measurement is needed in machine manufacturing. This research attempts to develop measurement method through feeding force, using strain gauge sensor. The aim of measurement of feeding force in this research is to find out the influence parameter of machine towards feeding force. The research used experimental method with design experiment Taguchi to know the influence of machine parameters to feeding force in turning process. The measurement tool is strain gauge sensor connected to cutting tool. The workspace is alluminium 6061 with 15 mm in diameter and 150 mm in length. The  parameters for this research are speed rate (140 rpm, 215 rpm, and 330 rpm), feed rate (0,043 mm/r , 0,065 mm/r , and 0,081 mm/r), and depth of cut (0,2 mm, 0,4 mm, and 0,6 mm). The result showed that speed rate is the most significant parameter, with the contribution percentage is 92 %. Speed rate and feed rate parameter have insignificant influence. The contribution percentage of speed rate is 2% while the feed rate has % contribution percentage. The conclusion of the research is that the bigger number of speed rate, the bigger feeding force it will have.

Abstract

The paper present the result of the study on the use of simulation software of ANSYS R15.0 version in attempt to simulate the load which is working on a screwed shaft of a shaping machine. This shaft was broken down during normal working and within limit of its life time. Therefore, the simulation would try to find out the cause of the failure. In order to simulate the load, the mechanical properties and chemical composition of the shaft were used as the input for modeling. The shaft is made of medium carbon steel of S 45 C in round shape. The finite element method (FEM) was used for analyzing. The modeling was started with a 3D redrafting the real dimension of the shaft in a computer aided design (CAD) model, then imported to the ANSYS system into FEM format. The mechanical and physical properties of the material was entered as the engineering data. Meshing was made to divide the component into several small elements. A combination of static and torsion load was applied to the shaft with a fixed position. The simulation results shown that von mises stress of 4.546 MPa was achieved. While, the first principal stress of 4.518 MPa, the third principal stress of 0.538 MPa. Other result revealed that the displacement was 0.001602 mm. Simulation also indicate that failure occurs at the slot a place where the pin was inserted to lock between the shaft and the bevel gear. The result is in accordance with the real failure of the shaft. To conclude, the ANSYS with FEM modeling has succeeded to simulate the failure of the screwed shaft.
