Answer 1

As your URL has two params you need to set TWO routes for the method. Change your route as

$route['blog/category/(:any)/page'] = 'Blog_Category_Post/page/$1/page';
$route['blog/category/(:any)/page/(:any)'] = 'Blog_Category_Post/page/$1/page/$2';

and now change config line base_url as following

$config['base_url']  = site_url('blog/category').'/'.$id.'/page';

finally your page controller should be

    public function page($categoryId){
     $this->db->select('id,categoryId');
     $this->db->from('t_blog_post');
     $this->db->where('categoryId',$categoryId);
     $query= $this->db->get();

    //$jml                        = $this->db->get('t_blog_post');
     $config['base_url']         = site_url('blog/category/').'/'.$categoryId.'/page';
     $config['total_rows']       = $query->num_rows();
     $config['per_page']         = 2; /*Jumlah data yang dipanggil perhalaman*/  
    $config['uri_segment']      = 5;    /*data selanjutnya di parse diurisegmen 3*/
    /*Class bootstrap pagination yang digunakan*/
     $config['full_tag_open']    = "<ul class='pagination pagination-sm' style='position:relative; top:-25px;'>";
     $config['full_tag_close']   ="</ul>";
     $config['num_tag_open']     = '<li>';
     $config['num_tag_close']    = '</li>';
     $config['cur_tag_open']     = "<li class='disabled'><li class='active'><a href='#'>";
     $config['cur_tag_close']    = "<span class='sr-only'></span></a></li>";
     $config['next_tag_open']    = "<li>";
     $config['next_tagl_close']  = "</li>";
     $config['prev_tag_open']    = "<li>";
     $config['prev_tagl_close']  = "</li>";
     $config['first_tag_open']   = "<li>";
     $config['first_tagl_close'] = "</li>";
     $config['last_tag_open']    = "<li>";
     $config['last_tagl_close']  = "</li>";
     $this->pagination->initialize($config);

    if ($this->uri->segment(5)) {
            $offset = $this->uri->segment(5);
        } else {
            $offset = 0;
        }

     $list_blogPost=$this->BlogCategory->get_post($config['per_page'], $offset,$categoryId);
     $list_lastblogPost=$this->BlogCategory->get_last_post();
     $list_blogCategory=$this->BlogCategory->get_category();
     $data=array(
        'title'          => 'Blog',
        'userId'         => $this->session->userdata('sh_userId'),
        'fullName'       => $this->session->userdata('sh_fullName'),
        'accountTypeId'  => $this->session->userdata('sh_accountTypeId'),
        'photo'          => $this->session->userdata('sh_photo'),
        'halaman'        => $this->pagination->create_links(),
        'offset'         => $offset,
        'listblogPost'   => $list_blogPost,
        'listlastblogPost'=> $list_lastblogPost,
        'listblogCategory'=>$list_blogCategory
        );
     $this->template->display_admin('blog_categorypost',$data);
}

Now test.
