[ABSTRAKPada skripsi ini, kebergantungan persamaan keadaan materi quark terhadap parameter isospin dikaji secara teoritik. Model materi quark yang digunakan adalah pengembangan dari model CDDM (Confined Density Dependent Mass) dengan menambahkan suku interaksi isospin pada massa quark. Selanjutnya model ini disebut CIDDM (Confined Isospin Density Dependent Mass). Model CIDDM diuji dengan membandingkan relasi massa-radius bintang yang dihasilkan dengan observasi astrofisika dan hasil prediksi tekanan materi quark pada daerah nilai rapat bilangan baryon yang besar berdasarkan perhitungan pQCD. Hasil yang kami dapatkan menunjukkan bahwa model CIDDM tidak bisa menjelaskan hasil perhitungan pQCD pada daerah nilai densitas baryon yang besar tetapi cukup konsisten dengan observasi bintang kompak dengan massa dua kali massa matahari untuk set parameter DI-2500. ABSTRACT;In this bachelor thesis, the isospin dependence in quark matter?s equation ofstate have been studied theoretically. The quark matter model used in thisstudy is an extended version of CDDM model where the isospin term in quark?smass is included. Then this model is called CIDDM (Confined Isospin DensityDependence Mass). CIDDM model has been tested by comparing mass-radiusrelation which come from astrophysical observation and the equation of stateobtained from perturbative QCD (Quantum Chromo Dynamics) calculation.We have found that CIDDM model cannot explain the equation of state frompQCD in large baryon density region but it?s maximum mass prediction is quiteconsistent with the one from compact stars observation. Namely the pulsar?smass is about two times larger than solar mass if we use the parameter setDI-2500., In this bachelor thesis, the isospin dependence in quark matter’s equation ofstate have been studied theoretically.
