I think you have to use crosstab, you can try this out...

select '000000000001' as Kode, sum(case when j.kode_barang='A' then isi
else 0 end) as isi_A,
sum(case when
j.kode_barang='B' then isi else 0 end) as isi_B,
sum(case when
j.kode_barang='C' then isi else 0 end) as isi_C from j_master_barang;
