Engineering Banksam Trashure

Banksam Trashure (Bank Sampah Trashure) is a digital waste bank application developed to help communities manage waste more easily, productively, and with economic value. The app serves as a bridge between residents and waste merchants — including banksampah, organic collectors, and inorganic collectors.

The core problem Banksam Trashure addresses is the gap between people who produce waste and collectors who can process it. Waste is often scattered because there's no convenient system for sorting, collecting, and rewarding proper disposal. Banksam Trashure closes this gap with two simple services and a reward model that turns waste into something valuable.

The Problem

In Kecamatan Pelaihari, Kabupaten Tanah Laut, South Kalimantan, waste management remains a challenge. In many areas, waste is still scattered because it's not properly managed. Public knowledge about waste sorting is limited, and disposal points are not evenly distributed.

For some villages, the nearest waste collection point is far enough that residents struggle or lose motivation to dispose of waste properly. As a result, waste accumulates in certain spots and pollutes the surrounding environment.

Meanwhile, there are organic and inorganic waste collectors who are ready to receive and process waste from the community. Organic waste collectors can use waste to support freshwater fish farming and poultry. Inorganic waste collectors can buy waste from residents to sell to larger collectors for recycling.

The problem isn't the absence of collectors — it's the absence of a system that connects them.

Six core problems

• Low awareness. Many residents haven't learned to sort organic and inorganic waste.
• Limited disposal points. Not every area has an accessible waste bank or collection point.
• Distance barriers. Some residents live too far from disposal locations.
• Scattered waste. Without an easy collection system, waste piles up in unmanaged spots.
• No digital connection. Collectors need supply, residents need access — but there's no platform linking them.
• Waste has no perceived value. Many see waste as something to throw away, not something with economic worth.

The Solution

Banksam Trashure solves this by offering a digital platform that connects residents with local waste merchants. The app provides two main services:

Pick-Up lets users request waste collection at their location. A merchant receives the request, travels to the user, verifies and weighs the waste, and completes the transaction with a reward.

Drop-Off lets users browse nearby merchants, select one, and deliver waste directly. The merchant verifies, weighs, and rewards on the spot.

Both services are designed to match different user needs — whether someone lives far from a collection point and needs pickup, or lives nearby and prefers a quick drop-off.

Waste Categories

Banksam Trashure separates waste into two categories, each with its own collection path and reward model:

Organic waste — food scraps, leaves, fruit peels, kitchen waste. These are used for freshwater fish cultivation, poultry feed, or composting. Rewards are harvest-based: fish, poultry products, or other benefits from processing partners.

Anorganic waste — plastic bottles, cardboard, paper, cans, glass, metal. These are sold to large-scale collectors or recycled into new materials. Rewards are cash-based, depending on type, weight, condition, and market price.

Reward Model

The reward system is what makes Banksam Trashure more than just a waste disposal app. By giving tangible value for waste, the app turns a chore into an opportunity.

Current rewards:

• Cash for anorganic waste — direct payment based on weight and market price
• Harvest for organic waste — fish, poultry products, or other benefits from cultivation partners

Future expansion includes app balance, e-wallet integration (GoPay, OVO, Dana), points and vouchers, and loyalty programs.

Core Features

The app provides 11 core features organized into four categories:

Getting Started — Login with email/password or Google Sign-In, home dashboard with campaign banners and quick access to services.

Core Services — Pick-Up request flow, Drop-Off delivery flow, merchant directory with map-based discovery.

Tracking & Notifications — Order status tracking (waiting, processing, pickup, done), push notifications for order updates.

Education & Profile — Environmental articles, user profile with address management, guides, and privacy controls.

How It Works

Pick-Up Flow

1. User opens the app and logs in
2. Selects Pick-Up service
3. Chooses waste category (organic or anorganic)
4. Fills in waste details
5. Sets pickup address on the map
6. Submits the pickup request
7. Order enters "Waiting" status
8. Merchant processes the request
9. Merchant travels to the user's location
10. Waste is verified and weighed
11. Transaction is completed
12. User receives reward
13. Order status changes to "Done"

Drop-Off Flow

1. User opens the app and logs in
2. Selects Drop-Off service
3. Chooses waste category
4. Browses merchant list
5. Selects a nearby merchant
6. Views merchant location on map
7. Delivers waste to the merchant
8. Merchant verifies and weighs waste
9. Transaction is recorded
10. User receives reward
11. Order status changes to "Done"

Technology Stack

The app is built with a practical, scalable stack:

• Mobile Frontend: Flutter — cross-platform mobile app for Android and iOS
• Backend: Laravel — REST API server on local VPS
• Maps: OpenStreetMap — location-based merchant discovery and pickup address selection
• Notifications: Firebase Messaging — push notifications for order updates
• Stability: Crashlytics — crash reporting and stability monitoring
• Payments: Manual cash payments at launch, with digital payment planned for future phases

Impact

Banksam Trashure aims to create measurable impact across three dimensions:

Environmental

• Reduce scattered waste in communities
• Encourage waste sorting at the source
• Increase volume entering the recycling pipeline
• Reduce burden on disposal sites

Social

• Increase public awareness of waste management
• Build clean living habits
• Form environmentally conscious communities
• Increase citizen participation in waste programs

Economic

• Create economic value from waste
• Help collectors get steady supply
• Open local collaboration opportunities
• Support circular economy at the community level

Development Roadmap

The product follows a four-phase development plan:

Phase 1: Product Validation (1–3 months)

• Test Pick-Up and Drop-Off with real users
• Activate initial merchants
• Collect feedback and fix critical bugs
• Target: 50–100 users, 3–5 merchants, 50 transactions

Phase 2: Operational Strengthening (3–6 months)

• Create pickup SOPs
• Standardize reward pricing
• Improve UI/UX and notifications
• Strengthen backend and data management

Phase 3: Feature Expansion (6–12 months)

• Price estimation, photo upload, chat, ratings
• Points system and digital wallet
• Admin and merchant dashboards
• Environmental impact reports

Phase 4: Area Expansion (12+ months)

• Expand to new villages and districts
• Partner with schools and communities
• Collaborate with local government
• Run mass education programs

Summary

Banksam Trashure is a digital waste bank platform that solves the connection gap between communities and waste collectors. Through Pick-Up and Drop-Off services, the app makes waste disposal convenient. Through a reward model, it makes waste valuable. Through education, it builds awareness.

The platform isn't just about transactions — it's about building a local movement where sorting, collecting, and utilizing waste becomes a new habit that benefits both people and the environment.
