Indonesian, often referred to as Bahasa Indonesia, is the official language of Indonesia and is widely spoken across the archipelago. Like any language, Indonesian has its own set of grammatical rules and structures that can be challenging for learners. One such area is the use of prepositions of agent. In this article, we will delve into the prepositions of agent in Indonesian grammar, providing examples and explanations to help you understand their usage and nuances.
Understanding Prepositions of Agent
In English, prepositions of agent typically include words like “by” and “with.” These prepositions indicate the doer of an action in passive constructions. For example, in the sentence “The book was written by the author,” the preposition “by” introduces the agent, who is the author. Indonesian has similar constructions but uses different prepositions and structures to convey the same meaning.
The Preposition “oleh”
The most common preposition of agent in Indonesian is “oleh.” This preposition is used to indicate the doer of an action, much like “by” in English. Let’s look at some examples:
1. Buku itu ditulis oleh penulis.
(The book was written by the author.)
2. Lagu itu dinyanyikan oleh penyanyi terkenal.
(The song was sung by the famous singer.)
3. Rumah itu dibangun oleh arsitek terkenal.
(The house was built by the famous architect.)
In each of these examples, “oleh” introduces the agent who performs the action. It’s important to note that “oleh” is used in passive sentences, where the focus is on the action rather than the doer.
Active vs. Passive Voice
To fully grasp the use of “oleh,” it’s essential to understand the difference between active and passive voice in Indonesian. In active voice, the subject performs the action, while in passive voice, the action is performed on the subject. Here are examples of both:
Active: Penulis menulis buku itu.
(The author writes the book.)
Passive: Buku itu ditulis oleh penulis.
(The book was written by the author.)
In the active sentence, “penulis” (the author) is the subject performing the action. In the passive sentence, “buku itu” (the book) becomes the subject, and “oleh penulis” indicates who performed the action.
Other Prepositions of Agent
While “oleh” is the most commonly used preposition of agent, there are other prepositions in Indonesian that can indicate the doer of an action, although they are less frequent and have specific contexts.
The Preposition “dengan”
“Dengan” typically means “with” in Indonesian, but in certain contexts, it can also function as a preposition of agent, especially when it implies cooperation or assistance. Here are some examples:
1. Masalah itu diselesaikan dengan bantuan teman-teman.
(The problem was solved with the help of friends.)
2. Proyek itu dikerjakan dengan tim yang berpengalaman.
(The project was done with an experienced team.)
In these examples, “dengan” suggests that the action was performed with the help or cooperation of the agent mentioned.
The Preposition “oleh karena”
“Oleh karena” is a more complex preposition that can indicate causation or reason, and it can also introduce the agent in certain contexts. It is often used in formal or literary Indonesian. Here are some examples:
1. Keputusan itu diambil oleh karena desakan masyarakat.
(The decision was made due to public pressure.)
2. Tindakan itu dilakukan oleh karena perintah atasan.
(The action was taken due to orders from the superior.)
In these examples, “oleh karena” indicates the reason or cause behind the action and introduces the agent responsible for it.
Contextual Usage and Nuances
Understanding the prepositions of agent in Indonesian also involves recognizing their contextual usage and nuances. Different prepositions may be more appropriate depending on the formality, style, and context of the sentence.
Formality
In formal writing or speech, “oleh” is the preferred preposition of agent. It is clear, direct, and widely understood. “Oleh karena” may also be used in formal contexts to indicate causation.
In informal contexts, speakers might use “dengan” to suggest cooperation or assistance, but “oleh” remains the standard choice for indicating the doer of an action.
Regional Variations
Indonesian is spoken across a vast archipelago with numerous regional languages and dialects. While “oleh” is universally understood, some regions might have unique expressions or prepositions for indicating agents. It’s essential for learners to be aware of these variations when traveling or communicating with people from different parts of Indonesia.
Common Mistakes and Tips for Learners
As with any aspect of language learning, there are common mistakes that learners might make when using prepositions of agent in Indonesian. Here are some tips to help you avoid these pitfalls:
Confusing “oleh” and “dengan”
One common mistake is confusing “oleh” and “dengan.” Remember that “oleh” is used for passive constructions to indicate the doer of an action, while “dengan” suggests cooperation or assistance. Practice using these prepositions in context to become more comfortable with their distinctions.
Overusing Passive Voice
While passive voice is useful, overusing it can make your sentences sound awkward or overly formal. Try to balance active and passive constructions in your writing and speaking. Use passive voice when the focus is on the action or when the doer is not as important.
Ignoring Contextual Cues
Pay attention to contextual cues that might influence the choice of preposition. Formality, regional variations, and the specific context of the sentence can all affect which preposition is most appropriate. Listening to native speakers and reading a variety of Indonesian texts can help you develop a better sense of these nuances.
Practice Exercises
To solidify your understanding of prepositions of agent in Indonesian, here are some practice exercises. Try translating the following sentences into Indonesian, paying attention to the correct use of prepositions of agent:
1. The letter was written by the teacher.
2. The cake was baked by my mother.
3. The project was completed with the help of the team.
4. The decision was influenced by public opinion.

Conclusion
Understanding the prepositions of agent in Indonesian is crucial for mastering the language’s passive constructions. The preposition “oleh” is the most commonly used to indicate the doer of an action, while “dengan” and “oleh karena” can also function as prepositions of agent in specific contexts. By paying attention to formality, regional variations, and contextual cues, learners can become more proficient in using these prepositions accurately. Practice and exposure to native Indonesian will further enhance your understanding and fluency in this aspect of the language. Happy learning!
