Vaccine is one of the biggest problem that happen in Indonesia. Almost 75% vaccine is frozen on shipment process from Province to healthcare in district. Vaccine usually is transferred using a vaccine box whose the temperature has to be maintained at 2-8°C. The newest technology of vaccine box uses adsorption cooling and solar energy to keep the cold chain. This technology is separated into 3 modules which are cooling module (contain zeolite and water), vaccine box, and solar heater. The cooling module using adsorption as the cooling process, where the adsorption makes a pressure drop and causes the decrease of the temperature. The decrease temperature will be used as source of the cooling in the vaccine box. After the zeolite in cooling module reach the saturation because of adsorption process, it has to be heated up using solar cooker as the media. The solar cooker collects the energy from the sun using the principle of greenhouse effect. This study aimed to analyze if the design of vaccine box using adsorption cooling system and 13x/cacl2 composite zeolite as the adsorbent is suitable or not for holding the optimum temperature for vaccines. From simulation using MATLAB, an integrated technical computing including computation, visualization, and programming, the vaccine box could reach temperature 5°C and can be maintained for 12 hours with COP is 0.146. For the desorption process, it needs heat 150 KW and 23 minutes to complete the process.
