Implementation Method Of Penetration Macadam Layer Road Work (Lapen) For Village Road Construction In Dusun Anyar, Pondok Kubang Sub-District, Central Bengkulu Regency, Province of Bengkulu
In today's advanced era, good access to transportation is highly necessary in daily life. Well-developed road infrastructure ensures that road users are more comfortable and can easily move from one place to another. Moreover, good road conditions bring positive impacts to the wider community. Therefore, strong, durable, comfortable, cost-effective, and well-targeted road pavement design is crucial. One such method is known as the Penetration Macadam Layer (LAPEN) road work. The Penetration Macadam Layer is a type of road pavement that uses graded coarse aggregates bonded together with penetration asphalt. This project aims to construct a pavement structure capable of effectively distributing traffic loads to the subgrade while providing a stable and durable road surface. The construction process includes subgrade preparation, laying coarse aggregates (Class A or B aggregates), spraying liquid asphalt (Penetration Asphalt 60/70 or MC-800) in accordance with technical specifications, applying a cover aggregate (chipping), and compacting using a tandem roller or pneumatic roller. The evaluation of the results is based on parameters such as density, layer thickness, and asphalt penetration level. The Penetration Macadam method has proven to be effective for light to medium traffic conditions and regions with limited budgets, resulting in a strong, stable road surface with good interlayer bonding. On this occasion, the writer presents the project titled “Implementation Method of Penetration Macadam Layer (LAPEN) Road Work on the Village Road Project in Dusun Anyar, Pondok Kubang Subdistrict, Central Bengkulu Regency, Bengkulu Province.”
Enhancing Efficiency In Nickel Ore Processing Through Redesigned Crusher Teeth
This study aims to evaluate and improve the design of crusher teeth on the Mineral Sizer Crusher used in the nickel ore processing operations at PT X. The primary issue identified was the discrepancy between the actual production capacity and the initial machine design specification, where the production capacity, initially targeted at 500 tons/hour, only achieved 120 tons/hour. Additionally, frequent machine shutdowns occurred due to material accumulation that could not be efficiently crushed. This research involves analyzing the initial design, evaluating the material used, and developing an optimized crusher teeth design using SCMnH11, a material known for its high resistance to impact and abrasion. The results indicate that the redesigned crusher teeth, with optimized geometry and material properties, successfully increased production capacity to 500–550 tons/hour and reduced the risk of machine stoppages caused by material blockages. This study concludes that optimizing the crusher teeth design and selecting appropriate materials can significantly enhance the operational efficiency and reliability of the machine in nickel ore processing.
