The 'd' here actually transliterates one of the two hindi/common indian language 'R's. One is the dental R (र), pronounced by putting the tip of your tongue at your teeth, and the other is the retroflex R (ड़), pronounced by putting the tongue at the roof of your mouth. It is a cross between a 'd' and an 'rh' sound. The retroflex 'd' (ड) is pronounced in a similar manner.
The second 'R' is used in jugaad here (जुगाड़), and it means to "cobble together" or "makeshift," which exacty what it is: makeshift, hastily cobbled together work done to get the weight off one's shoulder as soon as possible.
It can also simply mean "collect" or "collection", but it means the above in this context.
Edit: There is another 'R' (ढ़) which is pronounced like a (ड़) with an additional 'h'.
