The authority and leadership of the ‘Lord of the Flies” is one of the important themes. This power relation is divided into a symbol in the novel which is a dictatorial system with Jack as the leader, a democratic system with Ralph as the leader. Boys are in a shocking situation without any other choice. In the island, the boys themselves established their own new system and created society. There is no adult who precedes the role of authority, so the children resume power and assume roles. With this authority, the boys lose their innocence and become violent. It is the purpose of this essay to examine the various types of symbols used in novels and to show how they are tied to social power relations. If an airplane falls on an abandoned island without civilization, everyone can suffer injury especially children. First of all, if there are children without adults, many boys are embarrassed to do not know what to do. With these traumas on, boys learn to grow very quickly. Many innocent boys behave more violently because they are simply lost because they simply do not know the behavior of adults. They see violence as fun. Normally, adults will lead the role of authority and lead the children to stabilize their life on the island. But on this island where there are no adults, children begin to make their own society. At first, Ralph finds the ‘conch’ and uses it to gather the children on one side of the island. Then, after opening the meeting, everyone started to talk about how to pick a leader for the first time while talking about how to survive or rescue. All boys said select Ralph to a leader instead of Piggy showed ‘wisdom’ and Jack showed ‘leadership’. At that time as Ralph was chosen as the chief, there was a new law what makes the man who has the ‘conch’ as the leader. So conch becomes a new symbol that equal leader. Ralph takes responsibility for the boys and tells them what they must accomplish for rescue and survival. He approaches things in an organized, logical, and practical way and thinks about rescue first. As another testimony to his practicality, when he finds that no one dwells on the island, Ralph explains that boys must make a signal to attract the passing ship. After he obsess the signal fire. For example, “We’ve got to have special people for looking after the fire”-p.52. Not only Ralph but also other children want you to be mindful of the signal fire. At that time, Jack agreed to Ralph’s opinion. But through signal fire, their conflict is getting bigger. Ralph saw a ship emitting smoke from sea, but they could not be found. So Ralph identify the signal fire, but it was go out already, no fire, no heat, no boys to check the fire. However Jack only focus on to kill the pig, and describe how they killed the pig. So Ralph was really furious of them. Between Ralph and Jack’s tendency, direction, and purpose is being contrast. Jack goes to hunting with other boys to live and survive in the island. On the contrary, Ralph care to the signal fire as he rescue with his children to escape from the island . Since seeing the ‘beast’ in the mountains, Jack and Ralph have fought during a meeting to counteract the forces of the two and Jack left from Ralph. At the moment when Jack left from Ralph, other boys did not react which mean they did not follow and support Jack. Maybe at that time, the children were embarrassed by the sudden action of Jack. But after a time, the children go to join Jack’s group. Jack is better than Ralph as survival ability. He is strong, above all good at hunting so he can get a lot of food. So I think that the boys moved because they thought Jack’s group would be more stable to live on the island. Of course, Ralph’s survival ability is not bad. He is systematic and deliberate. He takes care of the fires to send rescue signals, and continues to make shelter to stay safe. But he has a weakness. Ralph’s hunting skills are weaker than Jack’s. Ralph is not interested in hunting and not bad, but when he acted as a leader from the beginning, he went Jack to hunting troops, and he did not hunt.
