String status = "orderSucces";
    Firebase ref = new Firebase("https://myfirebase-d8a8a.firebaseio.com/order");
    orderID = "-Kxi37Ro2oCPxQkb5L5u";
    Query query = ref.child(status).orderByChild("orderID").equalTo(orderID);
    query.addValueEventListener(new com.firebase.client.ValueEventListener() {
        @Override
        public void onDataChange(com.firebase.client.DataSnapshot dataSnapshot) {
            progressBar.setVisibility(View.VISIBLE);
            if (dataSnapshot.exists()) {
                for (com.firebase.client.DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
                    OrderModel data = postSnapshot.getValue(OrderModel.class);
                    orderModel.add(data);
                    adapter = new Adapter(getApplication(), orderModel);
                    //adding adapter to recyclerview
                    recyclerView.setAdapter(adapter);
                    progressBar.setVisibility(View.GONE);
                }
            } else {
                progressBar.setVisibility(View.GONE);
            }
        }

        @Override
        public void onCancelled(FirebaseError firebaseError) {

        }
    });
}

OrderModel.java

public class PemesananModel implements Serializable {

    public String orderID, paymentID, buyerName, buyerPhone, paymentMethod;

    PemesananModel() {}

    public PemesananModel(String orderID, String paymentID, String buyerName, String buyerPhone, String paymentMethod) {
        this.orderID = orderID;
        this.paymentID = paymentID;
        this.buyerName = buyerName;
        this.buyerPhone = buyerPhone;
        this.paymentMethod = paymentMethod;
    }

    public String getOrderID() {
        return orderID;
    }

    public void setOrderID(String orderID) {
        this.orderID = orderID;
    }

    public String getPaymentID() {
        return paymentID;
    }

    public void setPaymentID(String paymentID) {
        this.paymentID = paymentID;
    }

    public String getBuyerName() {
        return buyerName;
    }

    public void setBuyerName(String buyerName) {
        this.buyerName = buyerName;
    }

    public String getBuyerPhone() {
        return buyerPhone;
    }

    public void setBuyerPhone(String buyerPhone) {
        this.buyerPhone = buyerPhone;
    }

    public String getPaymentMethod() {
        return paymentMethod;
    }

    public void setPaymentMethod(String paymentMethod) {
        this.paymentMethod = paymentMethod;
    }
}

Since your JSON doesn't have a property called payment, it seems like you're simply reading the data at the wrong level in your JSON tree.

The solution is to attach your listener on the correct level in the tree, like this:

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference paymentRef = rootRef
    .child("order")
    .child("orderSucces")
    .child(orderID)
    .child("payment");
