Letakkan ham dengan posisi “berbaring” di dalam loyang. Tutupi ham dengan kertas aluminium tebal. Panaskan ham seberat 0,5 kg selama 10 menit. Periksa ham setelah waktu memasak berlalu setengahnya. Panaskan tiap potongan ham dengan microwave.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
Placing the cut side down helps trap moisture in the ham. It also prevents the glaze that normally comes on spiral sliced hams from drying out or getting stuck to the bottom of the pan. The ham itself should be covered, and the foil should wrap around the edges of the baking dish. Heavy aluminum foil (as opposed to regular aluminum foil) will help protect the ham from drying out. With your oven set at 325 Fahrenheit (163 Celsius), heat the ham for about 10 minutes for every pound (0.5 kg) of ham
