Asalamualaikum Wr Wb.
Setelah sekian lama browsing akhirnya dapet apa yang gue pengen, yaitu penyisipan code di blogspot. Untuk menyisipkan Code di blogspot kita harus menyisipkan script yang di buat oleh alexgorbatchev yang bernama SyntaxHighlighter. Menurut pengelaman gue browsing berjam – berjam dan analisa gue dari berbagai tutorial ternyata cara ini yang paling mudah dan 
Untuk menambahkan SyntaxHighlighter ini, seperti biasa kita harus masuk ke bagian dashboar –> Template –> Edit Html
Setelah itu cari code </head> dengan menekan tombol ctrl + f dan sisipkan script dibawah ini tepat di atas code </head>
