Abstract
Breast cancer is the type of cancer with the most and the highest cases causing mortality in Indonesia, so an effective treatment is required to reduce the incidence and mortality rate due to cancer breasts. Most breast cancer patients are diagnosed at an advanced stage so the treatment used are limited and the risk of death becomes higher. Along with the development of human genome sequencing technology, the genetic examination of breast cancer is considered as an examination that can be used for early prevention and treatment management personally. Based on the target variants detected, the genetic examination of breast cancer can be divided into two, namely the examination of germline variants and somatic variants. Germline variant examination is intended to predict the risk of breast cancer which can be used as an early preventive measure, while somatic variant examination is intended for cancer diagnosis and management therapy. NGS technology is able to detect both types of variants in a number of genes associated with breast cancer in several samples effectively and quickly. However, the data generated from NGS technology is very large and complex, so the role of bioinformatics is required in analyzing and interpreting data. By utilizing bioinformatics pipelines and tools, analysis of germline variants and somatic variants in breast cancer can be carried out accurately so that the results of genetic examinations can be used as a step to treat breast cancer.

Abstract
The addition of reflectors to solar panels is used to increase the intensity of sunlight received by solar panels so that the electrical power generated by the panels increases. In adding reflectors to solar panels, they must consider various factors to be able to increase the power generated without having a negative effect on solar panels , one of which is providing a cooling system. Therefore, research is needed to increase the power generated by solar panels and cooling systems that are suitable for overcoming rising temperatures due to the addition of reflectors. The study was conducted by varying the glass mirror reflector, aluminum foil reflector, angle of the reflector, and heatsink-fan cooling system. The research method used in this study was to compare 2 solar panel models, namely: solar panels with the addition of glass mirror reflectors / aluminum foil and heatsink-fan cooling systems, and solar panel models without any addition. The results show that the solar panel model with the addition of a glass mirror reflector / aluminum foil can increase the output power according to the angle of the reflector, the highest increase reaching 16.70% in the 450-angled aluminum foil mirror reflector. The heatsink cooling system is considered to be useful for reducing the temperature of solar panels, but the decrease is relatively small below 5%.
