Abstract

Akibat keausan yang terjadi pada impeller pompa, maka kapasitas pompa akan turun. Hal ini disebabkan  karena air yang kembali ke saluran hisap semakin banyak. Berkurangnya kapasitas ini menyebabkan turunnya efisiensi pompa karena kapasitasnya turun sedang daya penggeraknya tetap. Turunnya kapasitas dan efisiensi tersebut dapat dikurangi dengan cara memasang Jet-pump pada saluran hisapnya, sebab dengan adanya Jet-pump jumlah air yang kembali ke saluran hisap semakin kecil.  Untuk membuktikannya maka dilakukan pengujian karakteristik pompa tanpa Jet-pump dan dengan Jet-pump, kemudian dibandingkan hasil kedua pengujian tersebut. Juga untuk mengkaji perubahan kapasitas terhadap : head efektif , break horse power, water horse power, efisiensi dan NPSH. Kapasitas dan Efisiensi pompa dengan Jet-pump lebih besar dari pada pompa tanpa Jet-pump. Kapasitas yang bisa dicapai tanpa Jet-pump sebesar 1,1481 liter/det , setelah dipasang Jet-pump kapasitasnya naik menjadi 1,2501 liter/det, demikian juga efisiensinya naik dari 30,47 % menjadi 32,03 %. Parameter yang lain juga naik, seperti : WHP naik dari 0,039 HP menjadi 0,041 HP,  Head efektif naik dari 1,64 meter menjadi 1,75 meter

Abstract

Carbon Capture and Storage (CCS) is one of the global warming mitigation technology systems by reducing CO2 emissions into the atmosphere. This system is a series of implementations of processes that are related to each other, starting from the separation and capture of CO2 from the source of exhaust emissions (flue gas), transportation of captured CO2 to storage (transportation), and storage to a safe place (storage). If these emissions are released in large quantities, it will certainly cause various problems such as Global Warming. In the maritime transportation sector, one of the emissions that is widely produced by ships is exhaust gas from the ship's main engine when operating which is released into the atmosphere through the Funnel (chimney). One method that can be done is to separate carbon dioxide gas (CO2) contained in the exhaust gas with Membrane Technology placed on the Funnel. Technical analyzes is done by testing the vessel model then the results are developed with naval theories. This article will discuss how to filter carbon dioxide gas and membrane technology that can be used on ships.
