| Summary: | In recent times, meal-ready-to-eat has always been the choice of people out there. This isbecause MREs are easy to prepare; just by using a heater, the food can be served and eaten immediately. This MRE is also very convenient and user-friendly, and it is suitable even for people who rarely eat this type of MRE food. However, this MRE food has a problem for people who are outside or people who do not get enough heat to cook, for example, people who are busy at work or even people who are in hard-to-reach areas. For this reason, this self-heating pad was created and created to overcome this problem because it can generate heat without the need for external heat. Therefore, this research was aimed to find the best combination of calcium oxide and zinc to be placed in the self-heating pad together with food has been studied and recorded. This best combination was select based on the highest temperature obtained, longer duration sustained at the highest temperature. In relation to that, the reaction between calcium oxide and zinc using 100 ml of water was conducted experimentally, and the temperature was recorded. The highest temperature obtained, which is 76℃ is the result of a combination of 60 grams of calcium oxide and 10 grams of zinc, and it takes 20 minutes to reach the highest temperature. While 26℃ is the lowest temperature recorded when a combination of calcium oxide 40 grams and zinc 15 grams is used, and it takes around 20 minutes to reach the highest temperature. In conclusion, this combination has the potential to be one of the self-heating elements for self heating pads in the future, however further details study need to implemented in order to achieve 100℃. |
