 "SQLSTATE[HY000] [1045] Access denied for user 'homestead'@'localhost' (using password: YES) (SQL: insert into `siswa` (`created_at`, `jenis_kelamin`, `nama_siswa`, `nisn`, `tgl_lahir`, `updated_at`) values (2018-08-26 22:04:59, L, Agus Yulianto, 1001, 1990-02-12, 2018-08-26 22:04:59))

Ini script untuk insertnya

 Route::get('sampledata', function(){
	DB::table('siswa')->insert([
		[
			'nisn'	=> '1001',
			'nama_siswa' => 'Agus Yulianto',
			'tgl_lahir' => '1990-02-12',
			'jenis_kelamin' => 'L',
			'created_at' => '2018-08-26 22:04:59',
			'updated_at' => '2018-08-26 22:04:59'
		],
	]);

});
