Standing on the banks of the Way Besai River in Lampung, 31-year-old Joni Suranton intently observes the river’s flow, the lifeblood of the Besai Kemu Mini-Hydro Power Plant (PLTM). This vital facility generates an impressive 33.4 GWh of electricity annually. Periodically, Joni glances towards the trash filter – a critical indicator of the power plant’s production stability. His vigilant gaze underscores the continuous efforts required to harness the river’s energy.
This scene marks the beginning of Joni’s demanding routine as an operator at PLTM Besai Kemu. He is a guardian of the energy flow, working tirelessly within a relentless 24-hour cycle to ensure uninterrupted power generation. His role is central to maintaining the consistent operation of this crucial renewable energy source.
Joni is part of a dedicated team of eight colleagues in his division. “Our daily activity is cleaning trash,” Joni shared with Katadata.co.id in Lampung on a Saturday. He elaborated on their advanced methods: “We use a crane that can lift up to one ton. Typically, if the water level difference reaches four or five bars, it signifies dirty water, and we know it’s time to clean.” This highlights the practical and intensive nature of their work in maintaining the hydroelectric power system.
The debris they contend with isn’t limited to mere plastic or small twigs; often, tree trunks, bamboo, and other substantial materials are carried by the river’s powerful current. When these accumulate at the trash rack, the water level in the headpond can significantly drop, directly impacting efficiency. Joni emphasizes the severity: “If the trash rack is blocked by just 10 cm, the water in the headpond drops.” This critical vulnerability means that “trash inspections are conducted daily, sometimes countless times, depending on the volume of debris,” making vigilance a constant requirement for effective river maintenance.
The intake operations at PLTM Besai Kemu run non-stop, requiring round-the-clock dedication. The demanding work is split into two 12-hour shifts, ensuring continuous oversight. “Yes, it’s 24 hours,” Joni confirmed. “There are two shifts, day and night. The intake team consists of nine people, with three operators per shift.” This structured approach allows the power generation to remain uninterrupted.
Unlike some industrial settings, there are no dedicated dormitories for the operators. After their intensive 12-hour shifts, they return to their respective homes. Joni, for instance, lives conveniently close to the plant, allowing him to unwind and prepare for his next crucial shift.
Safety is paramount; before handling any equipment, operators must ensure all safety gear is properly worn. Once secured, their focus invariably returns to the relentless task of debris management. Maintaining a clean water flow is absolutely critical to ensuring optimal turbine performance. “If we want maximum turbine output, we focus on the trash. That’s the essence of it,” Joni stated, underscoring the direct link between meticulous cleaning and efficient electricity supply.

Operator Challenges: From Generators to Running Out of Fuel
No job is without its obstacles, and this holds true for field workers like Joni and his team. For operators at a mini-hydro power plant, the greatest challenges often stem from minor technical hitches that occur at the most inconvenient times. A prime example is the crane running out of fuel during a crucial trash removal operation. The crane and other hauling equipment are entirely dependent on fuel supplies for their functionality. “Sometimes, when we’re lifting trash, our generator’s fuel runs out,” Joni recounted with a slight laugh, highlighting a common, yet disruptive, issue.
When questioned about emergency situations in his role as an operator, Joni identified slipping, falling, and being struck by materials as the most frequently anticipated hazards. “If there’s an emergency, we report it to SHE (Safety, Health, and Environment) personnel or security, who are always on patrol,” he explained. “We prioritize immediately securing anyone involved in an incident from the point of danger.” This emphasizes their adherence to stringent safety protocols in a potentially hazardous environment.
Joni is far from new to the PLTM Besai Kemu environment, having a rich history with the facility. He previously served in the Asset division and held a role as a safety man before transitioning to his current position as an operator. He recalled the early days, “Initially, our focus wasn’t on the dam itself. We simply followed the instructions from our superiors.” This background provides him with a comprehensive understanding of the plant’s multifaceted operations and safety requirements.

From Arduous Labor to Streamlined Operations
Joni vividly remembers the arduous early days of his career as an operator. He notes that his work today is significantly easier, thanks to the introduction of the crane, which has vastly simplified the arduous process of trash removal. Prior to its arrival, all debris had to be cleared manually. “Alhamdulillah (Thank God), we now have a crane. It has been an immense help,” Joni expressed with relief. “Now, the water elevation remains stable. Before, when we relied on manual clearing, especially during floods, trash would completely cover the intake, causing the water level to drop drastically and making the turbine load unstable.” This technological improvement has not only made the job safer and more efficient but also ensured more consistent power generation.
Behind every megawatt of electricity flowing into the grid lies the crucial role of dedicated operators like Joni. Their tireless efforts ensure that the trash racks remain spotless, water elevation stays stable, and turbines are continuously monitored throughout the day. Their commitment directly contributes to the plant’s impressive output. The PLTM Besai Kemu consistently generates a robust electricity supply of 33.4 GWh annually, sufficient to meet the energy needs of approximately 16,000 to 22,000 households each year, making it a cornerstone of local sustainable energy provision.
Summary
Joni Suranton adalah operator di Pembangkit Listrik Tenaga Mini Hidro (PLTM) Besai Kemu di Lampung, yang menghasilkan 33.4 GWh listrik setiap tahun. Tugas utamanya, bersama timnya, adalah membersihkan sampah seperti batang pohon dan bambu dari saringan sampah sungai secara terus-menerus. Upaya ini sangat penting karena sampah yang menumpuk dapat menurunkan ketinggian air, secara langsung mempengaruhi efisiensi dan stabilitas produksi listrik PLTM.
Operasi pembersihan yang berlangsung 24 jam ini memastikan kinerja turbin optimal, dengan inspeksi harian yang krusial untuk menjaga aliran air tetap bersih. Meskipun ada tantangan seperti malfungsi peralatan, penggunaan derek telah sangat menyederhanakan pembersihan sampah, menjadikannya lebih aman dan efisien dibandingkan metode manual. Dedikasi ini memungkinkan PLTM Besai Kemu secara konsisten memasok listrik ke sekitar 16.000 hingga 22.000 rumah tangga setiap tahun.
