# Kesalahan LaTeX: Hanya dapat digunakan di preambel

Kesalahan ini muncul ketika Anda memasukkan sebuah paket atau kelas di isi utama dokumen Anda, alih-alih di preambel. Preambel dokumen terdiri dari semua yang ditulis sebelum **`\begin{document}`**. Di preambel, Anda menentukan jenis dokumen yang sedang Anda tulis, bahasanya, dan beberapa elemen lainnya. Misalnya, preambel dokumen normal akan terlihat seperti ini:

```latex
\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}

\title{First document}
\author{Hubert Farnsworth \thanks{didanai oleh tim ShareLaTeX}}
\date{February 2014}
```

Jika Anda menulis **`\usepackage{...}`** di isi utama dokumen (setelah **`\begin{document}`**) alih-alih di preambel, Anda akan menghasilkan pesan kesalahan yang ditunjukkan di bawah.

main.tex, baris 7

Kesalahan LaTeX: Hanya dapat digunakan di preambel.

Lihat manual LaTeX atau LaTeX Companion untuk penjelasan. Ketik H untuk bantuan langsung. ... l.4 \usepackage {amsmath} Perintah Anda diabaikan. Ketik I untuk menggantinya dengan perintah lain, atau untuk melanjutkan tanpa itu. \[1

Untuk memperbaiki kesalahan ini, pastikan bahwa semua **`\usepackage{...}`** perintah, serta **`\documentclass[...]{...}`**, ditulis sebelum **`\begin{document}`**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/id/kesalahan-latex/13-latex-error-can-be-used-only-in-preamble.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
