Abstract

In recent years, research in the marine field has focused on reducing exhaustemissions by increasing fuel efficiency and carbon dioxide emissions. Reducing carbonemissions in the industry can be achieved by using energy-saving devices that also functionto reduce fuel consumption. This device also serves to reduce frictional resistance at theship’s aft so that energy losing impact to fuel consumption can be prevented. Based on thiscondition, this study uses an wake equalizing duct type with symmetrical and asymmetricalNACA variations. The CFD (Computational Fluid Dynamics) method is used to analyze thecoefficient of thrust and coefficient of torque. The duct is added to increase the value of bothcoefficients. The analysis without NACA variations results thrust coefficient value of 0.1442and torque coefficient value of 0.01539. The NACA 0015 variation produces thrustcoefficient value of 0.215747279, torque coefficient value of 0.020711813 and its efficiencyincreases 10%. NACA 4412 variation produces thrust coefficient value of 0.208392027,torque coefficient value of 0.020178827 and its efficiency (?o) increases by 11%. Theconclusion is additional wake equalizing duct is able to align the flow at the ship’s aft so thatit can minimize the occured turbulent current.

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

The ocean is the largest source of potential energy in Indonesian country, one potential thatcan be expoloites is energy from sea wave and current which can be alternative to meet national energyneeds, ocean wave and current energy includes EBT resources which is rarely explored. Ocean wave andcurrent energy conversion can be converted into electrical energy by use the movement of sea waterwave, hydrokinetic Darrieus tubine is a conversion tool that can be used to convert kinetic energy intomechanical energy, In this case study, used angle of attack and solidity variation of the hydrokineticDarrieus tubine were used, the wave data used is the Southern Waters of Java Island, which is preciselyat Tanjung Bili Beach, Malang. By ussing airfoil NACA 0018 and profile Darrieus turbine diameter of 1m. Produce RMS CT and CP values with the stable is found on the solidty variation 0,15 with angle ofattack 10o TSR 0,25 omega (?) 0,5 with RMS value of CT 0,1512 and CP 0,075.

Abstract

COVID-19 cases will continue to spread throughout the world until 2023, including inIndonesia, and have many negative impacts, especially for the industrial world because it is difficultto enforce a minimum distance of 1-2 meters between employees. One technology that has highpotential to be applied is the air curtain. This journal analyzes push-pull ventilation to protectworkers from microdroplet inhalation. In this study, two variations of the push-pull ventilation speedratio (Vs/Vb) were used, namely 4 and 6. As well as using a variation of the push nozzle slope, namely10°. In this study, running was carried out with two models, namely modeling without a mannequinand with a mannequin. To complete this research, simulations were carried out using theComputational Fluid Dynamics (CFD) method using Salome, OpenFOAM, and ParaView software.So, the results obtained in modeling without a mannequin, the speed ratio of 6 is the most optimalratio with the least amount of average discharge that goes out of bounds, namely 0.582 m3/s. Whilethe results of the push-pull modeling with the mannequin show that no droplets penetrate the aircurtain at all variations of the velocity ratio, the velocity ratio of 6 is the velocity ratio that has aover-blow flow pattern that is very effective in holding down spray from droplets.

Abstract

Transmission of COVID-19 is still increasing in the world, such as in China andIndonesia. One of the reasons for the increasing number of positive cases of COVID-19 isthe occurrence of transmission from industrial clusters, the implementation of a minimumsocial distancing of 1 to 2 meters between workers is difficult to do. This is due to limitationsin layout, area, and industrial work systems. Thus, a system is needed to protect industrialworkers from potential exposure to COVID-19. One technology that has high potential to beapplied is air curtain. From these problems, this research will carry out an analysis of theoptimum push-pull discharge and air velocity, and the regime map for downward push-pullair curtain, the method used to carry out the analysis is Computional Fluid Dynamics (CFD)where the stages of the CFD process are preprocessing, processing, postprocessing. Thesoftware used to complete this final project is SALOME for the preprocessing,, OpenFOAMfor the processing, and for the postprocessing stage using ParaView. From the simulationresults that have been carried out, the results show that at a nozzle blow speed of 6,24 m/s,with a suction nozzle speed of 37,44 m/s, these are the optimum blow speed and suction nozzlevalues and are able to withstand droplet dispersion.

Abstract

Kerjasama antara ITS dengan Ponpes Al Khoiriyah Desa Wates, Kecamatan Sumbergempol, Kabupaten Tulungagung telah dimulai sejak tahun 2021 melalui skema abmas dan KKN Mahasiswa. Tahun 2023 lalu telah dibuat lampu dan sel surya di atas bukit Podo di kawasan Ponpes Al Khoiriyah oleh tim KKN. Namun, dari kaki bukit hingga puncak bukit belum terdapat tangga permanen yang memudahkan orang mendaki, dan hal inilah yang menjadi kesulitan tim abmas kami tahun lalu. Tangga ini menjadi salah satu hal penting untuk pengembangan kawasan wisata Glamping Podo Rukun (GPR) ponpes Al Khoiriyah agar pengunjung dapat naik ke atas bukit, melihat pemandangan dari atas bukit dan bagi pengelola juga memudahkan untuk melakukan pemeliharaan terhadap fasilitas di atas bukit. Dengan demikian, tujuan dari Abmas tematik dana departemen tahun 2024 ini adalah membuat tangga permanen di Bukit Podo. Kegiatan ini penting dalam rangka mengembangkan kawasan desa wisata untuk meningkatkan potensi daerah dan pertumbuhan ekonomi masyarakat yang mendukung SDG Pekerjaan Layak dan Pertumbuhan Ekonomi. Luaran dari kegiatan ini adalah publikasi di media massa, di jurnal abmas, dan video yang dilengkapi HAKI. Pengabdian masyarakat telah dilaksanakan pada tanggal 8-18 Juli 2024, dimulai dengan survey, pengadaan alat dan bahan, serta pekerjaan konstruksi tangga di bukit Podo secara intensif dalam jangka waktu sekitar 10 hari. Pada akhir kegiatan telah dilakukan kegiatan serah terima hasil abmas KKN kepada pihak ponpes.
