## 1. Apa itu Server Action di Next.js?

**Jawaban**

Server Action adalah fungsi asinkron yang hanya berjalan di server dan dapat dipanggil langsung dari komponen Client atau Server. Fungsi ini mengelola mutasi data (POST, PUT, DELETE) tanpa membuat API route eksplisit. Server Actions menyederhanakan kode dengan menghindari duplikasi API route + pemanggilan fetch sisi klien.

## 2. Bagaimana cara mendeklarasikan Server Action di file terpisah?

**Jawaban**

Untuk membuat Server Action di file terpisah, tambahkan direktif 'use server' di bagian atas file dan ekspor fungsi async. Pendekatan ini direkomendasikan untuk ketercapaian ulang dan pemisahan tanggung jawab. Fungsi kemudian dapat diimpor ke komponen Client atau Server mana pun.

## 3. Apa perbedaan antara Server Action dan API route?

**Jawaban**

Server Actions dapat dipanggil langsung dari komponen tanpa membuat endpoint REST eksplisit, sementara API routes memerlukan panggilan HTTP (fetch). Server Actions menyederhanakan kode dengan menghindari duplikasi route + panggilan klien. Keduanya optimal untuk mutasi sederhana, tetapi API routes tetap berguna untuk endpoint publik atau webhook.
