dc.description Abstract. Crushing Plant is a processing unit consisting of various tools where there are several continuous series of activities aimed at reducing the size of the material andesite rock. The process of destruction is the initial stage in the process of andesite rocks, after the process of rock destruction then the next stage is uniformity of rocks size before being sold to the market. PT Mitra Multi Sejahtera has one crushing plant units. Crushing plant with a production capacity with 500 tons/hour. PT Mitra Multi Sejahtera produces split 1, split 2, split 3 and stone ash. During the production process there are constraints that become obstacles and affect the production goals at the crushing plant, consequently the production target that has been set is not achieved, the production of crushing plant is currently 483,69 tons/hour while the production goals set by the company is 500 tons / hour. In the primary crushing stage, the result of Mechanical Avability (MA) = 91,22%, Phyisical Avability (PA) = 92,95%, Use of Avability (UA) = 78,79%, Effective of Utilization (EU) = 73,24 % In the first phase of secondary crushing stage I generated Mechanical Avability (MA) = 91.88%, Phyisical Avability (PA) = 92.61%, Use of Avability (UA) = 90.24%, Effective of Utilization (EU) = 83, 57%. There is lossing materials in this production process, total losing materials is 0,85 ton/hour or equal to 0.21% of total incoming feed.Key words : Crushing Plant, Obstacles, Production Goals, Losing Materials Abstrak. Crushing Plant adalah suatu unit pengolahan yang terdiri dari berbagai macam alat dimana terdapat beberapa rangkaian kegiatan yang bersifat kontinyu dan bertujuan untuk mereduksi ukuran material batu andesit. Proses penghancuran tersebut merupakan tahapan awal dalam proses pengolahan batuan andesit, setelah dilakukan proses penghancuran batuan maka tahapan berikutnya adalah penyeragaman ukuran batuan sebelum dijual ke pasar. PT Mitra Multi Sejahtera mempunyai satu unit crushing plant. Crushing plant dengan kapasitas produksi 500 ton/jam. PT Mitra Multi Sejahtera menghasilkan produk akhir split 1, split 2, split 3 dan abu batu. Selama proses produksi berlangsung terdapat kendala-kendala yang menjadi hambatan dan mempengaruhi target produksi pada crushing plant tersebut, akibatnya target produksi yang telah ditetapkan tidak tercapai, produksi crushing plant saat ini adalah 483,69 ton/jam sedangkan target produksi yang telah ditetapkan oleh perusahaan adalah 500 ton/jam. Pada tahap primary crushing diperoleh hasil Mechanical Avability (MA) = 91,22%, Phyisical Avability (PA) = 92,95%, Use of Avability (UA) = 78,79%, Effective of Utilization (EU) = 73,24% Pada tahap secondary crushing I dan II dihasilkan Mechanical Avability (MA) = 91,88%, Phyisical Avability (PA) = 92,61%, Use of Avability (UA) = 90,24%, Effective of Utilization (EU) = 83,57%. Terdapat kehilangan (losing materials) dalam proses produksi ini, total losing materials adalah 0,85 ton/jam atau sebesar 0,21% dari total umpan yang masuk..Kata Kunci : Crushing Plant, Hambatan, Target Produksi, Losing Materials
