The author has successfully conducted research on: dose calculation, irradiation time, and optimal boron concentration for stage II cervical cancer using Boron Neutron Capture Therapy (BNCT). This research is motivated by the increasing incidence of cervical cancer in Indonesia, which has the potential to cause death. The study also aims to assist in the management of cervical cancer in Indonesia using BNCT. The method involves simulating the geometry of cervical cancer tissue and surrounding healthy organs, which are then irradiated with neutrons from a 30 MeV proton beam produced by a cyclotron accelerator and directed at a beryllium target. The simulation was performed using the Particle and Heavy Ion Transport (PHITS) program version 3.30 with Beam Shaping Assembly (BSA) optimization based on existing references. The variables used include boron concentrations of 130, 140, and 150 µg/g of cancer tissue and irradiation models from left, right, and front directions of the phantom. The research results show that the absorbed dose received by the cancer tissue from the front direction is 50 Gy, while the doses to the rectum and bladder are 15.5 Gy and 5.2 Gy, respectively. The most effective irradiation time is 55 minutes and 40 seconds from the front direction of the phantom for stage II cervical cancer, and the optimal boron concentration is 150 µg/g of tissue, which results in less damage to healthy tissue
