About Indonesian Green Coffee Exporters | Martira Global
PT Martira Global Nusantara is a licensed Indonesian green coffee exporter, processor, and direct-trade agricultural partner headquartered in Medan, North Sumatra. We bridge more than 3,450 smallholder coffee farming families across Aceh, North Sumatra, West Java, and South Sulawesi directly with international roasteries and green coffee trading houses, backed by certified Q-Grader quality control, climate-controlled dry mills, and 100% EUDR geolocation compliance.
Corporate Enterprise Snapshot
Direct export facilities certified by Ministry of Trade Republic of Indonesia (Kemendag) and International Coffee Organization (ICO).
From North Sumatra Highlands to Global Container Terminals
Martira Global was born out of a fundamental recognition: while Indonesia produces some of the most sought-after volcanic microclimates in specialty coffee, traditional export intermediaries frequently obscured origin traceability, compromised moisture control through permeable jute bags, and depressed farmer revenues.
In response, our founders—combining background in agricultural agronomy and licensed Specialty Coffee Association (SCA) sensory grading—established our central processing dry mill in Medan. By eliminating speculative collector layers and installing state-of-the-art optical sorters, we created a streamlined corridor between Gayo Highlands, Lake Toba, Java Preanger, and overseas roasteries.
Mission, Vision & Foundational Values

Head of Sourcing & Smallholder AgronomyAgronomist specializing in shade-tree agroforestry and EUDR GPS polygon mapping across 14 cooperative networks in Aceh and Sumatra.
Partnering Directly with 14 Indonesian Cooperatives
Rather than relying on opportunistic spot brokers who pit smallholders against one another, Martira Global establishes multi-year purchasing agreements with organized farmer groups.
Every cooperative receives agronomic training, calibrated moisture meters for parchment checking, and a guaranteed price premium for red-ripe cherry sorting. Sourcing logs are maintained in our digital traceability ledger, enabling buyers to trace a container down to specific village collection points.
Active Cooperative Sourcing Hubs
Milling Infrastructure & Sorting Technology
State-of-the-art facilities engineered to eliminate physical defects and stabilize water activity.
Vibratory Size Screening
Multi-deck mechanical shaking screens calibrate green beans precisely into Screen 16, 17, 18, and 19+ jumbo fractions, ensuring uniform heat transfer during roasting.
Gravimetric Density De-stoning
Air-float gravity tables separate immature, insect-damaged, and low-density hollow beans, guaranteeing that only dense, flavor-packed seeds proceed to export bags.
Optical Bichromatic Sorting
High-speed optical cameras scan every single bean falling through pneumatic ejection chutes, removing black, sour, yellow, and fungus-damaged beans with microsecond precision.
Licensed Q-Grader Sensory Laboratory in Medan
No container leaves our dry mills without thorough cupping under official Specialty Coffee Association protocols. Our temperature-controlled cupping lab in Medan evaluates:
- ✓ Roast Sample Profile: Agtron/SCA color standard (58-63 ground / 63 whole bean).
- ✓ Cup Attributes: Fragrance, aroma, flavor, aftertaste, acidity, body, balance, clean cup, and sweetness.
- ✓ Moisture Testing: Sinar / Dickey-John calibrated dielectric moisture meters (±0.1% accuracy).
- ✓ Sample Library: 18-month reference sample retention for every dispatched FCL container.
Preserving Sumatra’s Rainforest Biodiversity
All Martira Global arabica lots are cultivated under dense shade-tree canopies (Erythrina, Albizia, and native citrus) that provide vital wildlife corridors bordering Gunung Leuser National Park. We strictly prohibit chemical defoliants, protect water catchment basins near washing stations, and recycle coffee pulp into organic compost for smallholders.
From Smallholder Cherry to Destination Seaport
A disciplined 5-stage export procedure engineered for cargo consistency.
Hand-picked red cherries at 20-22° Brix sugar level from GPS mapped smallholder plots.
De-pulping and parchment fermentation with strict pH tracking and raised bed sun drying.
Optical sorting, moisture testing (11.5%), and Q-Grader cupping approval at Medan lab.
Bagged in 60kg jute with hermetic multi-layer liners and desiccants for sea transit.
Container loading at Belawan/Priok with full phytosanitary, ICO, and EUDR DDR documentation.
Trusted by Roasters in 28 Countries
"Working directly with Martira Global removed the volatility we used to experience with Sumatra coffees. The cupping sample kit we received was an exact match for the 20ft FCL container delivered to Hamburg."
"Their EUDR compliance data was provided well in advance of vessel discharge at Rotterdam. Precise polygon coordinates, verified cut-off dates, zero friction with authorities."
"We purchase 8 containers of Lampung Robusta Screen 18 per harvest. The defect count has remained steadily below 11, and container stuffing video logs give our board complete confidence."
