This research is an initial study of the characteristics of magnetocaloric materials by engineering the cobalt ferrite system. The cobalt ferrite material will be doped with the element cupper (Cu) which has good electrical properties. This is done to improve its conductivity properties in addition to the presence of Cu atoms can reduce the magnetic hysteresis of the CoFe2O4 material. The metho…

Penelitian ini melakukan analisis neutron pada teras reaktor CANDLE Gas-Cooled Fast Reactor (GFR) dengan bahan bakar uranium metalik (U-10%wtZr) Berbasis OpenMC. Analisis bertujuan untuk memahami distribusi fluks neutron dan laju reaksi fisi di teras reaktor. Hasil penelitian menunjukkan fluks neutron yang lebih tinggi pada zona bahan bakar starter akibat laju reaksi fisi yang lebih tinggi, sem…
The Musi River estuary is one of several river mouths that empties into the East Coast of Banyuasin, South Sumatra. The Musi River estuary accommodates various components of pollutant that enter through the river flow. The purpose of this study was to analyze and study the quality of the waters of the Musi River estuary based on the concentration of heavy metals Cd and Zn in sediments and to de…
The research on photodegradation of congo red dye using MgFe2O4 nanomagnetic has been done. MgFe2O4 nanomagnetic, Mg(NO3)2.6H2O and Fe(NO3)3.9H2O with mole ratio (2:1) were synthesized using coprecipitation method. The success of MgFe2O4 synthesis were characterized using XRD, UV-VIS DRS, SEM-EDX, VSM and FTIR. The photodegradation process of congo red variables including the effect of concentr…
A malignant tumour of the cervix, also known as cervical cancer, is the fourth most common cancer in women. It became top priority in government concern since the high mortality rate in term of cancer that happen in women. To minimize this mortality rate, it needed to do an early detection, so it can be treated while it in the early stage. This research was developed to produce software that ca…
