Abstract

There is a case on KM Spil Rumi in the form of Lubrcating Oil (L.O.) cooler damaged due to leakage. The existence of this case is the basis of this research to find an alternative replacement with a redesign. The methodology used in this research uses LMTD (Log Mean Temperature Different). Based on the calculation results, it is found that the shell and tube heat exchanger has a better overall convection coefficient value with a value of 538.98 W/m2.C compared to the plate heat exchanger with a value of 459.19 W/m2.C. Although the overall convection coefficient value of the shell and tube heat exchanger is greater, the shell and tube heat exchanger has an overdesign value that is too large at 74.42%. Therefore, the plate heat exchanger with an overdesign value of 31.39% has a higher effectiveness value with a value of 64.3% compared to the shell and tube heat exchanger with a value of 46.4%.

Abstract

- Wind speed is the movement of air from areas of high pressure to areas of lowpressure. As the use of electric energy increases due to the growing human population in aregion, there is a need for renewable energy sources to convert renewable energy intoelectricity. Wind energy is highly potential if utilized, considering its relatively low utilizationfor electricity generation in Indonesia. In the initial stage of using wind energy for electricitygeneration, data on the wind potential of a region is required, thus an analysis of wind speedin several areas on Java Island is necessary. The wind speed data in this Final Projectincludes several regions in the Java Province, namely: Bandung, Banyuwangi, Bekasi,Gresik, Kudus, Malang, Semarang, Surabaya, Surakarta, and Tuban. The method used inmodeling wind speed involves the Weibull distribution, Rayleigh distribution, and Gammadistribution. Goodness-of-fit tests are applied to examine the best probability functions ofeach distribution to be analyzed. The distribution that meets the criteria of Coefficient ofDetermination, Chi-Square, and Root Mean Square Error is the Weibull distribution, asevidenced by the probability plots of the Weibull distribution, which closely match the actualdata from various regions. Areas with potential for wind energy to be converted intoelectricity are evaluated based on the percentage of wind speeds exceeding 2 m/s. The areaswith the highest potential are Tuban with a percentage of 56.89%, Malang with 56.71%, andBandung with 50.20%.

Abstract

Society is very dependent on fossil fuels, and currently Indonesia does not haveexcess oil reserves. According to the DEN, oil reserves will be exhausted in the next nineyears. As an alternative, wind turbines can be used. However, the factor hindering thisdeployment is the design of the wind turbines, which is lacking. MPPT is used in windturbines to optimize performance by determining the state of the wind turbine, thencalculating the power sampling algorithm, and then calculating the overall performance andefficiency of the wind turbine. State 1, Vci 1 m/s, Vr 6 m/s, and Vco 8 m/s provide the highestpower of the three. The H_Single Cp 0.47 and Tsr 4.5 turbines with a ratio of one rotor aresuitable for use in several areas on the island of Java. If you want a greater output powerfrom a wind turbine, then you can use a turbine with dual rotors, namely the HCR turbine,because it is capable of producing almost twice as much as a turbine with one rotor. Thearea with the most potential to generate electricity is in the Tuban area. Overall efficiencywith a maglev wind generator (model WKG-1000-200r) gives a Savonius efficiency of 18.2%,an H-Darrieus efficiency of 22.1%, an HCR efficiency of 63%, and an H-Single efficiency of42.3%.

Abstract

New and Renewable Energy (EBT) resources in Indonesia are still not fully utilized,especially from the the maritime sector. Currently, the EBT mix has only reached 11.2 percent, stillbelow the 2025 energy mix target of 23 percent and the potential for EBT which reaches more than 400Gigawatts (GW) has only been utilized at 10 GW or 2.5 percent of the total reserves. (EBTKE PublicRelations, 2021). The form of wave and current energy is one of the new renewable energies from thesea which has the potential to be used as electrical energy with very large energy reserves. In this FinalProject research, a 2D modeling simulation based on CFD (Computational Fluid Dynamics) wascarried out on the Darrieus hydrokinetic turbine as an ocean wave energy converter device.Simulations were carried out to analyze the effect of the blade profile on the Torque Coefficient (Ct)and Power Coefficient (Cp) values. In this study, wave data from one of the South Java Waters wasused. The highest Coefficient of Torque (Ct) and Coefficient of Power (Cp) values were obtained forthe NACA 0021 symmetrical blade profile with a variation of TSR = 0.25 and ? = 0.5, namely Ct =0.335 and Cp = 0.167 while for the asymmetrical blade profile NACA 63-415 with a variation of TSR= 0.25 and ? = 5 for Ct = 0.263 and Cp = 0.132

Abstract

In the roll bending process, sheet metal is straightened before rolling. With plates of fairly large dimensions, 6m to 8m in length and 1.5m to 2.5m in width, the alignment process is not easy and takes a lot of time. In this study, we designed an adjustable plate holder to overcome this problem. The design method used is Ulrich's method by creating his three design concepts which later select the best design according to selection criteria. The design of this tool used Fusion 360 software to perform a strength analysis to determine the number of stresses obtained for the loads received and functional analysis to determine if this tool is expected by running torque theory. Make sure it works according to the functions provided. Based on the selected design concept, the strength of the adjustable holder plate structure was analysed and the maximum stress value was 9,662 MPa. This adjustable plate holder can shorten the straightening process to 61 seconds. The total budget required to manufacture this tool is Rp 17,918,000.00. In future research, it is expected to take into account the overall loading and fabrication carried out to obtain more specific results.

Abstract

Missile Fast Boat (KCR 60M) with the type of patrol boat and Hospital Assistance Ship (BRS). In some maintenance processes carried out on the ship system, counted on average carried out for 2 weeks. But that is done for all different equipment and machinery. The topic taken was performance analysis and maintenance proposals for the strainer. Strainer is a support component that functions as an outside water filter that will enter the ship system, because the strainer is the initial entrance of water and easy to do checks and can extend the life time of components such as pumps and heat exchangers that exist in the system. And to analyze all of these things use the Failure Mode and Effect Analysis (FMEA) and Realibility Centered Maintenance (RCM) methods and the data used such as TTF (Time to Failure) and TTR (Time to Repair). The application of this method is obtained the right maintenance time and more effective. The application of this method to each system on the ship is a sea chest system, sea water cooler system, ballast system, getting an additional maintenance time of 88 hours or about 3 days for the maintenance deadline. In the fuel oil transfer & purifying system, the maximum maintenance time limit is 982 hours or 40 days. As for the oil fill & transfer system to get results which is a time difference of 4.208 hours or about 5 months earlier than company data, it can be a suitable scheduling proposal for each of these systems. And the maximum fouling factor for the strainer component is 3.21 mm. As a result, the life time possessed by each machine component will be longer and its performance becomes optimal especially for strainer components that don’t have a fixed maintenance schedule.
