Abstract

The Keban Agung Power Plant is a Steam Power Plant located in Kebur Village, West Merapi District, Lahat Regency, which requires coal as its main fuel with quality that meets the standards of PLTU specifications to optimize the combustion process and reduce SO2 emissions. One of the most important coal quality parameters that need to be considered in coal suppliers to coal-fired power plants is sulfur content. Priamanaya Energi Coal Pit Coal seam A has a sulfur content of 0.16, seam B of 0.28, while seam C of 0.91 and 1.12. High sulfur levels cannot enter the coal-fired power plant because it can cause damage to the equipment such as rusting (corrosion). Therefore, this study aims to analyze the quality of seam coal A, B, and C used in coal blending activities to meet the sulfur content value of seam C coal in accordance with the specification standards of the Keban Agung PLTU which is at 0.1 to 0.5. Based on the 10 calculations of the coal quality blending test, it shows that blending with a composition of 8:1 with a tonnage of 2430 tons succeeded in reducing the sulfur content value of coal seam C to 0.31.

Abstract

Penelitian ini bertujuan untuk mengevaluasi dan efisiensi cycle time produksi pada kegiatan hauling menggunakan Dump Truck Shacman X3000 di PT. Kumala Bahtera Utama. Cycle time merupakan waktu yang dibutuhkan untuk menyelesaikan satu siklus kerja hauling, mulai dari proses pemuatan, pengangkutan, pembongkaran muatan, hingga kembali ke titik awal. Penelitian dilakukan melalui observasi lapangan, pengumpulan data primer dan sekunder, serta analisis perbandingan antara cycle time aktual dengan rencana perusahaan. Hasil penelitian menunjukkan bahwa rata-rata cycle time aktual mencapai 4 jam 59 menit, lebih tinggi dari rencana 4 jam per siklus. Rata-rata produktivitas aktual sebesar 8,65 ton/jam, berada di bawah target 13,25 ton/jam. Ketidakefisienan disebabkan oleh antrean saat pemuatan dan pembongkaran, waktu tunggu (waiting time), serta lost time seperti waktu istirahat dan pemeriksaan unit. Upaya perbaikan yang direkomendasikan meliputi pengaturan ulang jadwal rotasi unit, penerapan sistem antrean digital, optimalisasi layout jalur hauling, serta pemanfaatan teknologi GPS dan sistem monitoring waktu secara real-time. Simulasi tanpa hambatan menunjukkan potensi produktivitas hingga 20 ton/jam. Hasil ini menegaskan pentingnya pengelolaan waktu operasional untuk meningkatkan efisiensi dan pencapaian target produksi.
