Abstract

Piping system is needed notice on group of high population people. Water flows come out from people residend sometimes unstable when used. This anomaly can be happened because factor of section diameter, pipe material, and flow debit passed through pipes elbow. This research intend to know effect section diameter, pipe material varians, flow debit of head losses and knowing coefficient losses consequent reynold number. This research is using factorial desain orthogonal array L12 then data analysis used Analysis Of Variance (ANOVA) with assistance minitab 16 software and contrast test (Scheffe’s Method). The results of this experiment head losses highest value of pipe section diameter 1 inch towards ¾ inch, PVC (Poly Vinyl Cholide) pipe material, and flow debit 20 liter/minutes is 42.33 mm. For head loses lowest value of pipe section diameter ¾ inch toward 1 inch, PE (Polyethylene) pipe material, and flow debit 10 liter/minutes is 5.33 mm, although highest coefficient losses of section diameter ¾ inch towards 1 inch, PVC (Poly Vinyl Cholide) pipe material, and flow debit 10 liter/minutes is 1.4602. ANOVA result and contrast test (Scheffe’s Method) concluded section diameter, pipe material, and fluid flow debit significant effect of head losses. Based the conclusion of research, reseacher suggest that small section diameter toward big section diameter, better pipe material and low flow debit if want to reduce head losses value of piping system.

Abstract

Penelitian ini dilatar belakangi dari satu pengamatan terhadap pengaruh variasi temperatur dan media pendingin terhadap kekerasan logam S45C. Perbedaan temperature dan variasi media pendingin dapat mempengaruhi kekerasan logam menggunakan pengujian Harnes brinel test. Tujuan penelitian ini adalah mendapatkan temperatur optimal dan media pendingin yang efektif agar didapatkan nilai kekerasan tertinggi pada logam S45C. Penelitian ini berupa matriks orthogonal L20 dengan tiga replikasi menggunakan rancangan faktorial. Variabel bebas yang divariasikan yaitu temperature proses carburizing, dan media pendingin. Variabel terikatnya adalah nilai kekerasan yang di analisis menggunakan Anova serta uji kontras metode Scheffe. Kesimpulan penelitian ini adalah semua faktor berjalan simultan dan mempengaruhi kekerasa logam. Berdasarkan main effect plot, kombinasi temperature carburizing 8500C dengan media pendingin oli menghasilkan kekerasan logam 145 kg/mm2 dan 148 kg/mm2 dengan nilai kekeerasan rata-rata 146,5 kg/mm2. Berdasarkan simpulan penelitian ini, direkomendasikan mengunakan temperatur carburizhing yang lebih tinggi dengan memvariasikan media pendingin yang lebih variatif.
