Answer 1

You can order by exp and set the limit to 1, that way only the lowest exp will be shown. It would look like this:

SELECT a.idbarang, a.nama,b.stokbagus, a.hargaJual , b.exp FROM barang a LEFT JOIN detail_barang b on a.idbarang = b.idbarang
WHERE a.status = '1' ORDER BY b.exp LIMIT 1;

Answer 2

If you want to display the smallest exp for each nama , you need to use GROUP BY . Try this:

SELECT a.idbarang, a.nama,b .stokbagus, a.hargaJual, MIN(b.exp)
FROM barang a
LEFT JOIN detail_barang b ON a.idbarang = b.idbarang
WHERE a.status = '1'
GROUP BY a.idbarang
