\section{PENDAHULUAN}
This section should briefly explain the background of the study, provide a short review of the pertinent literature, state the originality or novelty of the research, and state the research objectives. This is an \textit{example} of \textit{italicized} text (\textit{The quick brown fox jumped over the lazy dog.}); \textbf{don't use bold text} unless it is called for by the content.
\section{METODE PENELITIAN}
In research articles, the materials and methods used in the study should be described together—first the materials, and then the methods. Enough information should be provided to enable repetition of the research. For commercial sources of the materials, the name of the company, and the town and country in which they are headquartered should be indicated. To avoid an excessively long methods section, methods that have already been published should be indicated with a reference, with only the relevant modifications described.
\subsection{Persamaan}
Equations should be directly referenced in the text, and typeset using the available \LaTeX\, commands, as shown in Equation \ref{eq:1}.
\begin{equation}
J(x) = Li(x) + \sum_\rho Li(x^\rho) - \text{log}\,2 + \int^\infty_x \frac{dt}{t(t^2 - 1) \text{log}\,t}
\label{eq:1}
\end{equation}
\noindent Long equations can use the \verb|aligned| environment to make them fit in a single column, as in Equation \ref{eq:2}.
\begin{equation}
\begin{aligned}
J(x) &= Li(x)\\ &+ \sum_\rho Li(x^\rho)\\ &- \text{log}\,2\\ &+ \int^\infty_x \frac{dt}{t(t^2 - 1) \text{log}\,t}
\end{aligned}
\label{eq:2}
\end{equation}
\subsection{Daftar}
This is an ordered list:
\begin{enumerate}
\item First item,
\item Second item, and
\item Third item.
\end{enumerate}
\noindent Please do not use unordered lists.
\section{HASIL DAN PEMBAHASAN}
Both the results and discussion of the research should be combined in a single section. Describe the results first, and present all data as concisely as possible, in the form of tables or figures (if appropriate).
The discussion should be an interpretation of the study's results in the context of previous research. Avoid simply repeating the results, or excessive citations. Instead, the works being cited should be relevant to the results being discussed.
\subsection{Tabel}
Size a table to fit in a single column (Tabel \ref{tab:1}) or across two columns (Tabel \ref{tab:2}). Avoid large tables (i.e. those that fit more than a single page), unless absolutely necessary; otherwise, considering making them supplementary material. Tabel \ref{tab:3} shows various advanced options you can use to present your data, as well as the best practices for alignment, both horizontally and vertically. Note also that sentence case is used for headers ("Left-aligned column" not "Left-Aligned Column").
Every table and figure should be cited in the text in numerical order (i.e. Tabel 2 cannot be cited before Tabel 1). Place table footnotes below the table, indicating them with superscripted lowercase letters or asterisks (for significance values and other statistical data).
\subsubsection{Judul tabel}
Every table should have a caption that is concise but clear enough to explain its main components independently from the text. Use sentence case. If the table contains previously published material, cite the original source at the end of the caption. If the results are expressed as a percentage, state the absolute value(s) that correspond to 100\%.

\subsection{Gambar}
Ensure that the figure will fit into either one column (Gambar \ref{fig:1}) or two columns (Gambar \ref{fig:2}). Images should be of sufficiently high resolution to be easily viewable when printed or on high resolution screens (minimum of 300 dpi).
Every figure should be cited in the text in numerical order (i.e. Gambar 2 cannot be cited before Gambar 1). Figures should be referred to as "Gambar" not "Fig." Denote figure parts with lowercase letters (e.g. Gambar \ref{fig:3a}, Gambar \ref{fig:3b}).
\subsubsection{Format gambar}
Photographs must have internal scale markers and symbols, and arrows or letters should contrast greatly with the background. Fira Sans is the recommended typeface for text within figures (if you don’t have it installed on your computer, you can download it from Google Fonts). Otherwise, a sans-serif such as Open Sans or Helvetica may be used. Where photographs of gel, autoradiograms, and so on have been processed to enhance their quality, this should be stated.
\subsubsection{Judul gambar}
Every figure should have a caption that is concise but clear enough to explain its main components independently from the text. If the figure contains previously published material, cite the original source at the end of the caption.

If a funding source contributed to the design, data collection, analysis, or writing of the manuscript, or the decision to submit it to \textit{Jurnal Rekayasa Proses}, this should be clearly stated.

\section*{REFERENCES AND CITATIONS} % Delete this heading and section when typesetting
For the purposes of efficiency and conciseness, aim for 10--25 references.
Use a reference manager such as Zotero or Mendeley to build your reference list, save the file as "references.bib", and then upload it to the \verb|references| folder. Alternatively, copy and paste the file contents into the \verb|references.bib| file. All references should be formatted in a manner compatible with BibTeX.
A reference must be cited for it to appear in the reference list. For most cases, you only need to cite a reference in one of two ways: \\
\noindent \verb|\citet{Smith2000}| if it appears in the beginning or middle of a sentence; e.g. "\citet{Smith2000} observed that precision is important in science." \\
\noindent \verb|\citep{Smith2000}| if it appears at the end of a sentence; e.g. "In science, precision is important \citep{Smith2000}."
If you have cited and formatting your reference correctly, it will automatically appear in the reference list, as shown below.
