The food that we eat is made up of different types of macro molecules. Energy are stored in the chemical bonds of these macro molecules in form of chemical energy. When humans consume these food, the chemical energy in the food is transferred into their systems and it is this energy that is used to carry out all the life activities. This chemical energy can be inter converted into various forms. When the body needs warmth, the chemical energy will be converted to thermal energy to produce heat.

The energy converted into thermal energy by the body is chemical energy stored in food. Through metabolism, the body breaks down food to release this energy, which is then converted to heat to maintain body temperature. This process is essential for maintaining homeostasis and proper bodily function.

Bangsa Indonesia sudah mengenal sistem politik dan pemerintahan sejak sebelum masuknya Islam, dibuktikan lewat prasasti, seperti dari Kerajaan Kutai. struktur pemerintahan mulai bisa dilacak sejak masa Sriwijaya, di mana prasasti menyebut adanya keputusan raja, saksi, dan imbalan.Bukti sejarah yang cukup lengkap berasal dari masa Majapahit, seperti kitab Negarakertagama, yang menggambarkan kondisi nyata tentang politik, budaya, dan ekonomi, tulisan-tulisan ini tidak hanya bersifat mitologis, tetapi juga memberi gambaran jelas tentang sistem pemerintahan sebelum kedatangan Islam
