Alternative energy is now becoming concerned globally. The energy shortage and problem due to deforest had made people try to exploit rene wable energy in order to tackle the problem. Although solar cooker is still not common but it had been proved that it can be a good tool if it is well designed and constructed. Solar box cooker (SBC) that was designed and constructed by previous student, M r. Then Kuck Shee, still had a lot of potential for improvement. In his thesis, he did not study the humidity in the SBC’s chamber. In fact, humidity had effect on the efficiency and performance of the SBC. Therefore, fundamental of SBC, characteristic of humidity, and other factor that affect the performance of SBC was studied in the present work. Then, based on the experiment result, it is found that air in the SBC’s chamber is finally saturated and this stimulate more heat lost to the environment as the air temperature drop. Hence, the temperature of the cooker will drop greater than the case where the air does not saturated. In order to reduce the effect of the humidity to SBC, it is recommended that humid absorbent may be able to be put inside the cook er chamber when cooking but it need to be made sure that the absorbent would not affect the safety of the food. Also, ceramic can be put inside the SBC’s chamber to increase the heat storage and efficiency.
