777 goes to Ayer Hitam, Machap, Spg Renggam,
Kulai, all the west side places. 777 only ply
between Ayer Hitam and Larkin.
39, 133, 133A, 200, 208 all goes to Masai. Only
39, 200 and 208 start their journey from Larkin,
to JB city centre, then head towards Masai. 133 and
133A will start their journey from Masai, making a loop at
JB centre city, and head back to Masai. I remember that there is
also Causeway Link sv from Larkin to Masai, but does not loop at JB
city centre, its either 55 or 66.
If you are referring to Jaya Jusco Permas Jaya,
this shopping centre is in Permas Jaya, not Masai.
Masai is a small town beside Pasir Gudang there. Permas Jaya is
housing estate, about 10 km away from Masai town, but still under
Masai region. So you cannot take Masai buses to Permas Jaya.
For going to Permas Jaya, can take Maju sv 10, Causeway
Link sv 22 and Transit Link sv 123. You can take these
buses from JB, at the bus stop adjacent to City Sq, opposite Caltex
Petrol Station. Alternatively can take from Post Office also.
From JB city centre, Permas Jaya will ply thru the Tax Free Complex
( Kompleks Bebas Cukai ), followed by Jalan Pasir Pelangi, Bakar
Batu and you will cross a high bridge, where you can see Senoko
Power Station in Singapore, when landing at the other side of the
bridge, you will enter Permas Jaya, the bus will continue straight,
until you see MacDonalds' at the left side, at the traffic light
junction of MacDonalds', you should be able to see Jaya Jusco. The
road name is Jalan Permas Jaya Utara.
