Batching Plant Operational Project - PT Meares Soputan Mining & PT Tambang Tondano Nusajaya

PT Tambang Tondano Nusajaya

Following the successful completion of the batching plant reactivation project owned by PT Tambang Tondano Nusajaya (TTN) in North Sulawesi at the end of 2024, PT Anggun Permai Tekindo (APT) continued its strategic partnership in the subsequent year with a focus on optimizing production operations. As a critical facility in the construction industry, the batching plant plays a key role in ensuring precise, standardized, and consistent material mixing processes to produce high-quality concrete in accordance with project specifications. Supported by automated systems and advanced technology, all production stages—from weighing to mixing—are monitored in real time to ensure strict quality control, operational efficiency, and risk mitigation. The produced material is then carefully delivered to underground work areas using dedicated transport systems to maintain its integrity and performance during application. Within this scope of work, APT is responsible for the production of shotcrete at a capacity of up to 40 m³ per shift, including comprehensive quality control processes covering material analysis and compressive strength testing. APT’s commitment is reflected through the implementation of rigorous quality standards and the provision of reliable operational solutions, supporting the sustained success of TTN’s mining operations.

Slope Protection & Erosion Control Public Road Girian-Likupang, Sulawesi Utara

PT Tambang Tondano Nusajaya

Located in the Girian–Likupang area, North Sulawesi, a slope protection initiative for PT TTN MSM was successfully completed as part of regional infrastructure development. This project showcases the execution quality of Aptekindo Mitra Solusitama (AMS) in delivering engineering and mining services. Conducted from September to October 2025, the scope included soil nailing, installation of 80 kN hexamesh, Erosion Control Type 3, and vegetation reinforcement. The project achieved 100% completion in just 41 days—32% faster than planned—with a Schedule Performance Index of 1.32, marking it as one of AMS’s fastest slope protection projects. All key deliverables were completed with high accuracy and zero incidents, supported by efficient manpower utilization, precise material management, and strict quality control without any non-conformance reports. This project stands as a strong representation of AMS’s capability in slope protection, geotechnical construction, and mining support services through precise execution, disciplined quality, and efficient project management.

GROUTING & INJECTION - Rehabilitation of Ball Mill-2 Foundation – PT ANTAM

PT Aneka Tambang

To ensure structural reliability and optimal performance of production equipment, PT Anggun Permai Tekindo was entrusted to carry out grouting and injection works at the Foundation of Ball Mill – 2 in the Processing Plant area of PT Aneka Tambang Tbk – UBPE Pongkor. The project began with a thorough inspection of the work area, including initial identification of the base plate and concrete walls as the basis for determining the work method. Chipping and concrete cutting were then performed according to technical requirements, followed by pinion plate installation and precise leveling using survey measurements to ensure alignment with specifications. Formwork was installed, and Sikagrout 215 material was prepared and mixed in accordance with procedures before being applied to fill all voids beneath the base plate. This grouting process enhanced the strength and stability of the structure, resulting in a more solid foundation ready to support operational loads. In addition, injection works were carried out to repair cracks in the concrete walls. Cracks were opened, drilled, and fitted with packers before resin was injected gradually until fully filled. Final inspections confirmed optimal repair results. With the completion of these works, the Ball Mill – 2 foundation is now restored to a safe, stable, and reliable condition, ready to support ongoing operations.

Batching Plant Operation

PT Tambang Tondano Nusajaya

A new batching plant for concrete production has been established to support underground development activities at Toka Tindung. This initiative encompasses a comprehensive service scope, including structural construction, plant operation, admixture supply, supervisory support, and stringent quality control. The project involves replacing the existing batching plant with a more productive and efficient steel structure design. Operational services include the provision of skilled manpower for daily operations and maintenance. Admixture supply covers essential components such as superplasticizers, accelerators, retarders, silica fume, and fiber to meet specific underground shotcrete and concrete performance requirements. Additionally, dedicated quality control measures are implemented to ensure consistent and reliable concrete output throughout the project.

Non-Explosive Demolition Agents (NEDA): A Modern Way to Break Rock Without Risk

PT Tambang Tondano Nusajaya

In this project, AMS implemented the Non-Explosive Demolition Agents (NEDA) method, a calcium oxide–based solution designed to fracture rock and concrete without blasting. The process begins with drilling holes into the material, followed by the insertion of a NEDA-water mixture that generates high expansive pressure exceeding 112 MPa, breaking the material internally along its natural weak planes. This method operates without explosions, excessive vibration, or shock impact on surrounding areas. Initial cracks typically appear within 6–12 hours and develop optimally within 24–48 hours, depending on material conditions and ambient temperature. These advantages make NEDA highly effective for sensitive environments such as underground mining sites, residential areas, and active operational facilities. Through precise technical planning—from drilling patterns to crack control—AMS ensures accurate, efficient results while minimizing damage to adjacent structures. In addition to enhancing safety, this approach supports environmentally responsible practices by eliminating smoke, vibration, and operational disruption, positioning AMS as a reliable partner for safe, efficient, and controlled demolition solutions.

West Wanagon Slope Protection at Grasberg Mine

PT Freeport Indonesia

The prestigious slope protection project at West Wanagon, Grasberg Mine, has been successfully implemented despite the challenging high-altitude environment. Situated at an elevation of 4,283 meters above sea level, where the ambient temperature averages around 5°C, the project required robust and reliable ground support solutions. The slope protection system consists of dry shotcrete using prepackaged Sikacrete Gunite 103, known for its durability in cold conditions, and a composite steel system incorporating galvanized wire mesh and friction bolts to ensure surface stability and long-term reinforcement.
