Manometer Design For Measuring Head Losses In Piping Test: Rancang Bangun Manometer Untuk Alat Ukur Head Losses Pada Uji Perpipaan Fernando, Ekki; Fahruddin, A'rasy
Indonesian Journal of Innovation Studies Vol. 13 (2021): January
Publisher : Universitas Muhammadiyah Sidoarjo

For the manometer that will be used in this study, using a U column type manometer filled with a fluid for measuring pressure, this manometer was designed using a simple tool at the time of manufacture. This manometer will be tested for its level of accuracy in the Head Losses test on the piping system. That is by using 3 types of fluids, namely resin, glycerol, and mercury where the pressure is generated from the flow of water in a straight pipe and an Elbow where this Manometer is placed in a straight pipe and also in the Elbow so here using 2 Manometers for testing. Then the test is carried out according to the specified variables, in order to obtain research data. After that determine the results of the pressure measurement of the 3 types of fluids used. The pressure measurement uses water discharge measuring 20, 15, and 10L/min. Then determine each result from each fluid where each fluid is experimented 3 times to determine the average value. If you have obtained the average value of each height difference (∆h) in each fluid, then determine the pressure value (Pa). The results of the Head Losses test on the piping test show that the resin value is close to the mercury value while the glycerol value is quite far. This shows that the density value of each fluid has an influence on the pressure value of each fluid. Keywords – Manometer; Pipe; Pressure; Head losses; resins; Glycerol; Mercury

Metal Inert Gas (MIG) welding method is a gas arc welding that uses a welding wire as well as an electrode. In the Metal Inert Gas (MIG) welding process, the heat from this welding process is generated by a welding arc formed between the wire electrode and the workpiece. The purpose of this study was to determine the tensile strength of the welding results in the connection process with Metal Inert Gas (MIG) against aluminum (Al) 5083 series 6 mm thick, the welding was carried out with various current strength treatments, namely 120 A, 130 A, 140 A. and Argon gas discharge 5 lt/minute, 10 lt/minute, 15 lt/minute in each welding process. This research is useful to know and understand about the analysis of the welding process on aluminum 5083 with a thickness of 6 mm with Metal Inert Gas (MIG) welding process using vertical (3 grove) welding techniques. The method used in this study is the analytical method, which is a method for testing by adding different treatments of current and discharge variations of Argon gas during the welding process of the specimen, so that different welding strengths will be obtained in each specimen.

The implementation of an automatic lathe, utilizing hydraulic drive and PLC programming, stands as a significant advancement in industrial engineering aimed at augmenting productivity while circumventing additional labor requirements. Through meticulous research, it was discerned that the predominant issue plaguing the production process was the occurrence of stoppages due to irregular or unstable dimensions in the output, particularly concerning the Item Bush K0JA Left. Employing methodologies such as SIPOC analysis and the 4M framework revealed that the root cause primarily stemmed from machine-related factors, exacerbated by fluctuations in the installation, resulting in misalignments and subsequent dimension inaccuracies. Addressing this, a targeted intervention involving the addition of locking bolts to the material fixture mitigated the stoppage occurrences significantly, with the operator rectifying positioning irregularities on average 1200 minutes per month. This intervention not only enhanced operational efficiency but also yielded tangible cost savings, amounting to Rp 578,000 monthly or Rp 6,936,000 annually, attributed to the prevention of production downtime. The implications of this study underscore the importance of proactive measures in streamlining manufacturing processes, thereby optimizing resource utilization and economic viability. Further research avenues could delve into the optimization of maintenance protocols for automated machinery and the exploration of advanced sensor technologies to preemptively detect dimensional inconsistencies, thus bolstering overall production resilience and efficacy. Highlight: Advanced machinery integration boosts manufacturing efficiency. Root cause analysis reveals process optimization insights. Cost savings demonstrate practical impact of production enhancements. Keywoard: Automatic lathe, Industrial engineering, Productivity enhancement, Dimensional accuracy, Cost savings

The ship design industry today needs innovation, especially in terms of speed boat design, to improve efficiency and stability. The study aims to analyze the influence of the variation of the bow flare angle on the obstacles on the speed boat. Through numerical simulations using Maxsurf Resistance software and Savitsky Pre-Planing, Savitsky Planing, and Holtrop calculation methods, the study analyzed variations in bow flare angles of 25º, 30º, and 35º at speeds of 17, 19, and 21 knots. The simulation results showed that the 35º bow flare angle gives the lowest impediment of 34 kN and requires a power of 367,163 kW at a speed of 21 knots, making it a more efficient choice compared to the 25º and 30º angles which yield the highest impedance of 34.2 kN and requires 369,739 kW power. This analysis confirms that a larger bow flare angle can reduce barriers and improve energy efficiency, which is important for the design and operation of speed boats. These results show that choosing the right bow flare angle can improve ship speed efficiency by reducing obstacles and fuel consumption. The results of this research are expected to be beneficial to the designers and operators of speed boats in achieving optimal performance.

Boundary layer adalah lapisan batas yang terbentuk akibat gesekan antara permukaan penampang dan fluida, sehingga terjadi gradiensi kecepatan. Penelitian ini mengamati gradiensi kecepatan fluida pada boundary layer dalam pipa lurus menggunakan metode eksperimental. Distribusi kecepatan fluida diukur menggunakan pipa akrilik berdiameter 1” dan jarum tumpul berdiameter 1,5 mm yang menyerupai tabung pitot dengan sistem perbedaan tekanan stagnasi dan tekanan statis. Fluida dengan berbagai viskositas dan laju aliran diuji untuk memahami pengaruhnya terhadap karakteristik lapisan batas. Dengan flowrate 10 liter/menit menunjukkan hasil pengukuran kecepatan fluida meningkat seiring bertambahnya jarak radial pada dinding pipa mulai dari =2 mm (0,334 m/s), =5,5 mm (0,341 m/s), =7,5 mm (0,425 m/s), =10,5 mm (0,438 m/s), dan pada =12,7mm (0,443 m/s). Kecepatan tertinggi tercatat di titik tengah pipa yang membuktikkan bahwa hasilnya sesuai dengan karakteristik boundary layer, di mana gaya gesekan dan viskositas berkurang.
