You are missing one thing. In your controller, you are accepting the $konsumen model object. But you didn't define how your $konsumen will convert to the model object. Because from URL you are getting an id.

To solve this you need to do some settings in your RouteServiceProvide class. Below is the code you need to add in your provider:-

public function boot()
{
    Route::model('konsumen', \App\Konsumen::class);

    parent::boot();
}

After this, your code will work.

This is one drawback of using resource in laravel route. It does create all the CURD routes, but it has its own standards that you need to follow. So when you have created

 Route::resource('konsumen', 'KonsumenController');

This in turn generated the routes that you can see in your screenshot. Take a look at the update route, it expects a parameter. So whereever you are using konsumen.update route you also need to pass a parameter konsuman. So it would be like this

route('konsumen.update', ['konsuman' => <someValue>])

Just like @PhucLam said

You forgot add param to route('konsumen.update').

It should be route('konsumen.update', ['konsuman' => $id])

$id is the id of konsumen record you're editing.

Try replacing the form action tag value in

edit.blade.php

to <form action="{{ '/konsumen/'. $konsumen->kde_konsumen) }} " method="POST">

You forgot to write required in kde_konsumen

$request->validate([
        'kde_konsumen',
        'nma_konsumen' => 'required',
        'alm_konsumen' => 'required',
        'tlp_konsumen' => 'required',
    ]);

to 

$request->validate([
        'kde_konsumen' => 'required',
        'nma_konsumen' => 'required',
        'alm_konsumen' => 'required',
        'tlp_konsumen' => 'required',
    ]);
