The system averted IDR 282.97M in total tax liability across the farmer base, saved farmers an average of IDR 187.4K each, and drove NPWP registration to 58.7% of users.

In 2022, new Indonesian tax regulations shifted responsibility for tax payments on transactions above IDR 20 million from digital platforms to individual farmers. For Jiva, this introduced regulatory and financial risk. For farmers, it introduced something more personal: tax deductions that would directly reduce their income.
Smallholder farmers in Indonesia, like most people, approach digital financial systems with natural caution, especially when money is being taken rather than given. Any surprise deduction, any unexplained calculation, any moment of confusion risked breaking the trust Jiva had worked to build.

Before designing, I worked with our research team to understand how farmers perceived taxes, NPWP status, and digital deductions.
We conducted 20 semi-structured interviews across three regions: East Java, South Sumatra, and South Sulawesi.

We conducted 20 semi-structured interviews across three regions: East Java, South Sumatra, and South Sulawesi.
Through field visits, usability tests, and in-depth interviews, farmers repeatedly voiced three significant challenges.
Confusion about how taxes were calculated, the legal jargon was overwhelming.
Skepticism toward digital financial tools, they feared hidden costs.
Struggles with navigating the UI, important tax information was overlooked.

Participants were recruited through our field team and represented a range of transaction volumes (under IDR 20M/month to over IDR 1B/month).
Sessions were conducted in-person in Bahasa Indonesia, with simultaneous translation for the design team.

Legal language failed in practice.

Farmers skimmed or ignored legal terminology entirely. Long-form policy explanations were not read.

Many farmers didn't realize that an inactive or missing NPWP doubled their tax rate (0.5% vs. 0.25%) but the information had never reached them in actionable form.

Advance Awareness: Home Screen Banner
Design goal: Signal upcoming changes before deductions begin.
Designed a persistent banner for the home screen that appeared 30 days before tax enforcement began.

2. Deep Understanding: Knowledge Base
Design goal: Provide exhaustive and verifiable explanation for farmers who wanted to go deeper.
I designed a dedicated knowledge base section with three content types:
Plain-language explainers
We rewrote policy documentation into conversational Bahasa Indonesia, removing all legal jargon.Peer explanation videos
Based on the research finding that farmers trusted other farmers, we produced short videos featuring farmers explaining tax implications in their own words.

Contextual Nudges: Transactional Flows
Design goal: Reinforce understanding at the moment of decision.
I mapped every flow where tax deductions would eventually appear:
Truck booking confirmation
Cost breakdown screens
Historical transaction records
Payment receipt screens
For each, we designed contextual banners that appeared before the deduction was shown, not after.

Trust couldn't be built through UI alone.
I traveled with the training team to conduct in-person sessions in three regions.
These sessions:
Introduced the new tax system in person before it appeared in-app.
Walked through calculation examples using the same logic as the product.
Created space for questions that wouldn't surface through a screen.
Farmers could practice the mental model before encountering real deductions.
This wasn't traditional "design work," but it was essential to the outcome.
The interface and the training operated as a single system.

Reflection
Realistic prototypes are an ethical requirement for financial systems.
When money is involved, users are evaluating trustworthiness. Simplified numbers break that evaluation.
Information hierarchy influences trust more than visual polish.
The difference between a confusing deduction and a clear one often came down to when information appeared and how much context preceded it.
Designing for compliance requires attention to emotional safety.
Legal accuracy isn't enough. Farmers needed to feel confident. That required a different kind of clarity, one that respected the anxiety inherent in seeing income reduced.
Product impact compounds when paired with operational support.
The interface and the training sessions weren't separate workstreams. They were two expressions of the same design intent: help farmers face complexity with confidence.
