A mobile service designed around the complete recycling loop.
Kiloin was prepared for the 2022 Business Plan Competition as a Software Engineering Technology project at IPB Vocational School. The proposal combines product design, system planning, operations, market entry, and financial projections.
Company
Tanaka Nawasena Company
A service business for collecting and recycling plastic and cigarette waste.
Vision
Reduce waste accumulation
Create a structured channel for waste disposal and transform collected materials into products that can be sold again.
Problem
Recycling is not yet practical or connected
The project asks how digital technology can make recycling more structured, practical, and accessible.
My contribution
UI/UX Designer
Focused on shaping the interface, user journeys, interaction structure, and prototype experience for Kiloin.
Make recycling structured enough to operate, simple enough to join, and valuable enough to sustain.
Waste enters through Ko-Put and returns as value through Ko-Mart.
Instead of presenting the two features as isolated products, the service is shown as one circular flow: collect, process, and return value to the community.
01
Ko-Put
Users classify plastic or cigarette waste, enter the pickup location and details, then monitor collection status until completion.
Design outcome
Lower participation effort
Initial audience
The proposal connects market entry, operations, finance, and the business model.
The original competition document is translated into a readable digital ledger rather than a set of screenshots. All figures below are projections presented in the 2022 business plan.
Market thesis
Start in Bogor, learn locally, then expand.
The plan targets Android users across age groups, with students, university students, waste collectors, and recycling-minded communities as the earliest segments.
Strength
Pickup service and higher waste value
Kiloin collects waste directly from users and connects it with products that have renewed commercial value.
Weakness
Low public interest
The service depends on users caring enough to sort and distribute recyclable waste.
Opportunity
Education can grow participation
Explaining the long-term impact of accumulated waste can attract communities and early adopters.
Threat
Larger competitors with stronger technology
Established organisations may have wider logistics coverage, more advanced systems, and greater capital.
Go-to-market sequence
Alpha and beta testing
Collect criticism and suggestions, then use them as the basis for improving the main features.
Bogor socialisation
Introduce the improved application locally and use early users as the first distribution channel for awareness.
Layered digital marketing
Combine campus advertising, public-service advertising in Bogor, Google Ads, and YouTube Ads.
The database connects people, pickups, waste inventory, and marketplace transactions.
The class diagram is kept as the single technical visual. The surrounding explanation decodes the system into readable modules so the page does not depend on a dense screenshot alone.
Decode the architecture
Identity and access
Separate user, customer, employee, address, and status records so authentication and operational roles remain traceable.
usernasabahpegawaialamatstatusUse-case layer
The supporting use-case diagram centres on login and separates employee management, customer management, waste delivery, waste pickup, and Trashshop activities.
Twenty-eight screens are organised as five user journeys, not a screenshot wall.
Only one screen is shown at a time. Select a journey to understand its role, then move through the relevant wireframes inside the phone stage.
Entry and education
Splash screen
Introduce Kiloin, explain accepted waste, and communicate how pickup and Kiloin Coin work before users create an account.
Screens in this journey
Kiloin was not only an interface exercise; it was a connected product-and-business system.
The strongest lesson is that service design, database structure, operational roles, market strategy, and financial assumptions must reinforce the same user promise.
One service loop
Ko-Put and Ko-Mart make more sense when shown as connected stages of a circular-economy journey.
Operations need structure
The data model reveals that a simple pickup screen depends on identity, schedules, waste records, payments, stock, and fulfilment.
Business assumptions need validation
The projections provide direction, while real-world testing would still be required to validate demand, logistics cost, pricing, and adoption.
