Abstract
Pada saat ini kebutuhan energi dari fossil fuel cenderung
mengalami peningkatan pada tiap tahunnya.. Fossil fuel
merupakan energi yang tidak dapat diperbaharui, sedangkan
kebutuhan terhadap bahan bakar tersebut masih cenderung
meningkat, sehingga hal ini berpotensi menurunkan persediaan
fossil fuel seiring bertambahnya waktu oleh karena itu diperlukaan
sumber energi alternatif yang berguna untuk mengurangi konsumsi
energi fossil fuel. Berbagai sumber energi alternatif telah banyak
dikembangkan diantaranya adalah Hydraulic Electro Mechanic
Shock Absorber (HEMSA)
Pada penelitian ini, tertuju pada peningkatan kinerja sistem
transmisi daya Hydraulic Electro Mechanic Shock Absorber
(HEMSA) generasi keempat dengan dua selang kompresi satu
selang ekspansi untuk rasio silinder 30 mm : 40 mm dengan
pembebanan akumulator akibat eksitasi impuls dan periodik pada
tingkat variasi yang lebih kuantitatif. Pengukuran energi bangkitan
dilakukan dengan menggunakan quarter car suspension test rig.
Pengujian dialkukan dengan memasang Hydraulic Electro
Mechanic Shock Absorber (HEMSA) ini pada alat tersebut yang
kemudian akan diberikan massa uji yang merepresentasikan ¼ dari
kendaraan (city car).
Dari penelitian ini didapatkan nilai konstanta redaman
HEMSA dua selang kompresi satu ekspansi tanpa pembebanan
sebesar 595.035 Ns/m. Energi bangkitan HEMSA dua selang
kompresi satu ekspansi, ketika frekuensi 1.3Hz yaitu sebesar 0.37
Watt, ketika frekuensi 1.5 Hz ialah 0.64 Watt, dan ketika frekuensi
1,7 Hz sebesar 2.14 Watt.

At this moment, the energy requirement of fossil fuel tend
to increase in every year. Fossil fuel is non-renewable energy,
meanwhile that requirement fuel is still grow up, thus based on this
situation, it can reduce the allocation of fossil fuel and need the
alternative energy sources that can be used for reduce
consumption of fossil fuel energy. Many kind of the alternative
energy sources are more developing likes Hydraulic Electro
Mechanic Shock Absorber (HEMSA).
In this research, focused on improving the performance of
the fourth generation of power transmission system Hydraulic
Electro Mechanic Shock Absorber (HEMSA) that consist of two
compression hose and one expansion hose for 30mm : 40mm ratio
of cylinder with accumulator charging that is caused by impulse
excitation and periodic on more quantitative level variation.
Measurement of evocation energy is done by using quarter car
suspension test rig. Testing is done by installing this Hydraulic
Electro Mechanic Shock Absorber (HEMSA) on that instrument
and then it will be given the trial period that represent ¼ of car
(city car).
From this research, it has been gotten the damping constant
value of HEMSA that consist of two compression hose and one
expansion hose without imposition of 595.035 Ns/m. The evocation
energy of HEMSA that consist of two compression hose to
expansion is happen when. on the frequency of 1.3Hz is 0,37 Watt,
on the frequency of 1.5Hz is 0.64 Watt, and on the frequency of
1,7Hz is 2.14 Watt.
