Adaptability in Action: How Longguang Delivered More Than Just Efficiency to a Jakarta Organic Fertilizer Producer

Southeast Asia is rich in organic fertilizer raw materials—palm shells, rice husks, and sugarcane bagasse are abundant. Yet the region’s hot, humid climate and raw material moisture levels of 50–70% create serious challenges for production equipment. What does it take for a production line to thrive in this environment? The partnership between Longguang and PT. Green Harvest in Jakarta offers a compelling answer.

A Challenge Typical of Southeast Asia

Founded in 2015, PT. Green Harvest specializes in converting agricultural waste into organic fertilizer for local plantations and European export. Like many producers in the region, the company struggled with aging equipment ill-suited for high-moisture materials.

With Indonesia’s tropical climate, raw material moisture often exceeded 60%, surging past 70% during the rainy season. The old system suffered from frequent “shaft sticking” during mixing, clogging in the granulator, and rapid die wear—requiring replacement every two weeks. Product quality suffered, with poor pellet uniformity and high powdering rates leading to customer rejections. Overall equipment effectiveness (OEE) hovered below 60%, severely limiting output and export capacity.

Longguang Solution: Adaptive Design, Not Just Equipment

In late 2024, PT. Green Harvest connected with Longguang at an industry exhibition. Rather than offering standard machinery, Longguang’s team conducted multiple online meetings and a two-week on-site assessment to develop a fully customized solution.

1. Core Machinery Selection

Crushing: A Vertical Chain Crusher was installed. Its high-strength wear-resistant chains handle feed moisture up to 55%, while the vertical structure eliminates clogging and wall-sticking, ensuring uniform particle size.

Granulation: A Rotary Drum Granulator with an anti-stick stainless steel liner was provided. The drum rotation uses centrifugal force and gravity to form round, uniform pellets. An automatic spray system adjusts liquid ratios in real time for high-moisture inputs.

Drying & Cooling: A rotary dryer and cooler with optimized lifting plates improved heat exchange by 20%, maintaining final moisture below 12%.

2. Process Automation

An automatic batching system with PLC controls precisely regulates raw material proportions, shortening the fermentation cycle from 25 days to just 10–12 days. An online moisture monitor provides real-time data to optimize granulation and drying.

3. Climate-Specific Design

All motors feature IP55 protection for Indonesia’s rainy, humid conditions. Electrical cabinets include moisture seals and cooling fans, while high-temperature grease and an automatic lubrication system reduce manual maintenance.

Results: Data That Validates Adaptability

Commissioned in February 2025, the line has delivered exceptional results:

Hourly Output: Increased from 5 to 7 tons (+40%)

OEE: Rose from ~60% to over 92%

Monthly Downtime: Reduced from 35 hours to under 7 hours (80% reduction)

Granulation Rate: Improved from 75% to over 95%

Pellet Breakage Rate: Dropped from 8% to below 3%

Power Consumption: Cut by 12% per ton

The finished pellets are round, smooth, and uniform, helping PT. Green Harvest achieve EU organic certification and secure new orders from the Netherlands and Germany.

Client Testimonial

“Longguang not only provided advanced machinery but also solved the moisture-related headaches that plagued us for years,” said Mr. Agus, Production Director at PT. Green Harvest. “We used to dread the rainy season—whenever materials got wet, the line would frequently shut down. Now, even with continuous rainfall, the equipment runs steadily. Our operators were fully trained in just two days. And the after-sales service is remarkable—most issues are resolved remotely. We’re planning to add a fully automatic packaging line later this year.”

Conclusion: More Than Just Efficiency

The PT. Green Harvest case proves that success in Southeast Asia’s organic fertilizer market depends not on having the most features, but on offering the strongest adaptability. From raw material characteristics to climate conditions and operational habits, every detail determines whether equipment can truly take root.

Longguang delivers more than machinery—it provides production solutions built on deep regional understanding, designed for stable, consistent performance. That is the value we create: not just improved efficiency, but equipment that becomes a trusted, long-term production partner.
