Abstract

The aim of this research was to determine the properties of the PB 260 clone rubber using the Averrhoa type coagulant. The natural coagulants used in this study were Averrhoa bilimbi and Averrhoa carambola. The latex used was 150 ml of PB 260 clone rubber with a concentration of 100% natural coagulant of 75 ml and 2% formic acid. The rubber properties that were tested were Po, PRI, DRC, ash content, dirt content, volatile matter content and Mooney viscosity. This research also uses a special treatment in the form of centrifugation speed. The higher the centrifugation speed, the higher the pH value of the natural coagulant and the lower the H+ ion value, which accelerates the coagulation time of the latex. In natural coagulant extract, the highest values of Po, PRI, DRC, ash content, dirt content and Mooney viscosity were obtained at 0 rpm for Averrhoa bilimbi extract with values of 40%, 94.17%, 32.83%, 0, 32%, 0.038% and 77 MU. Meanwhile, in the test for volatile matter content, the highest value was found in Averrhoa carambola at 5000 rpm with a value of 0.23%.

Abstract

Plate and Frame Heat Exchanger (PFHE) is a plate and frame type heat exchanger that is efficient and effective in improving energy efficiency. Research using PFHE aims to determine the effect of increasing the flow rate of hot fluid on heat exchanger performance. This research was conducted at a flow rate variation of 0.7 L/min, 0.9 L/min, 1.1 L/min, 1.3 L/min, 1.5 L/min, 1.7 L/min, and 1.8 L/min with 180 seconds of testing each variation and recording data every 2 seconds. The cold fluid used is tap water and the hot fluid used is distilled water. The results showed that with the increase in hot fluid flow rate, the performance of PFHE also increased because the effectiveness of NTU (Ɛ-NTU) increased. The Ɛ-NTU value of unidirectional flow is 25.37% - 44.87% and in the opposite direction 37% - 68.39%. The largest Ɛ-NTU value in the countercurrent flow indicates that the countercurrent flow is more effective than the unidirectional flow. In addition, increasing the flow rate increases the Reynold's number (Nre) and Nusselt's number (Nu) which indicates the greatest convection heat transfer occurs at the highest flow rate.

Abstract

Panas atau kalor merupakan energi yang dapat berpindah dikarenakan perbedaan temperatur. Dalam melakukan perpindahan panas, dibutuhkan sebuah alat agar mendukung terjadinya perpindahan panas. Alat perpindahan panas yang digunakan pada penelitian ini adalah Shell and Tube Heat Exchanger (STHE). Penelitian ini menggunakan program SCADA yang dapat melakukan proses akusisi data dan kontrol terhadap variabel dependen yaitu laju alir fluida panas sehingga diharapkan data yang ditampilkan pada program SCADA dapat merepresentasikan pengaruh laju alir dan arah aliran terhadap analisis performa alat penukar panas tipe STHE. Penelitian dilakukan dengan memvariasikan laju alir fluida panas pada rentang 0.8 L/min – 1.8 L/min, dimana pada alat ini memiliki maksimum laju alir 2,1 L/min. Dari penelitian ini didapatkan bahwa efektivitas tertinggi sebesar 0,44 pada laju alir fluida panas 1.8 L/min dengan aliran fluida berlawanan arah. Dari hal ini, dapat disimpulkan bahwa laju alir fluida dan arah aliran fluida mempengaruhi efektivitas alat penukar panas, namun bukan hanya mempengaruhi efektivitas alat penukar panas, laju alir dan arah aliran fluida juga mempengaruhi analisis yang lainnya seperti bilangan Reynold, perubahan temperatur rata-rata logaritmik, Number of Transfer Unit (NTU), dan juga efektivitas NTU. Laju alir pada alat penukar panas berpengaruh terhadap besarnya panas yang akan diserap maupun dikeluarkan sehingga, ketika laju alir mengalami peningkatan maka efektivitas alat penukar panas juga akan mengalami peningkatan dikarenakan hal ini dipengaruhi oleh besarnya panas yang dikeluarkan maupun yang diterima.
