Abstract

PT. Cipta Bersama Sukses merupakan salah satu industri yang bergerak di bidang pertambangan batubara di Sumatera Selatan yang merupakan salah satu kontraktor yang bekerja sama dengan PT. BSPC. Salah satu permasalahannya adalah ketidaksesuaian antara excavator dan dump truck yang mengakibatkan keterlambatan pada saat operasi produksi. Untuk itu diperlukan kajian kesesuaian alat gali dan angkut agar target produksi dapat tercapai serta dilakukan perhitungan produktivitas alat gali muat dan alat angkut dalam kegiatan coal getting. Setelah dilakukan analisa data, diketahui produktivitas yang dicapai excavator CAT 330GC selama 1 jam kerja dari pengukuran aktual di lapangan adalah 156,27 MT. Sedangkan dump truck Hino FM 260JD selama 1 jam kerja dari pengukuran aktual di lapangan adalah 31,52 MT. Dalam kegiatan coal getting di PT. CBS menggunakan armada 1:3 dengan 1 excavator dan 3 dump truck. Berdasarkan pengukuran di lapangan cycle time alat gali muat adalah 19,11 detik dan cycle time alat angkut adalah 731,9 detik, sehingga diperoleh match factor sebesar 0,63 atau MF < 1 artinya excavator sedang menunggu dump truck.

Abstract

PT. Mineral Sukses Makmur is a company engaged in iron ore mining with an IUP area of 73.4 Ha. Overburden stripping production target of PT. Mineral Sukses Makmur in September 2022 amounted to 43,700 bcm while the realization was by using the Caterpillar 320D (01) Excavator and Caterpillar 320D Excavator (02) loading equipment of 28,024 bcm or 64% of the production target. Production of overburden stripping did not meet the target due to obstacles that caused high loss time on the digging equipment, according to field observation data. Additional productivity research on equipment working hours is needed so that the overburden stripping production target can function properly and maximize the effective working time of the loading and unloading equipment. One of the appropriate methods used to overcome this problem is the Overall Equipment Effectiveness (OEE) method, which is a method for measuring the performance of machines or equipment used in industry by considering various production losses. After that, a Fishbone diagram is used to identify the underlying causes and effects behind the production failure of overburden stripping. From the simple linear analysis equation, a simulation can be carried out to obtain the maximum loss time limit of the working hour constraints of the loading and unloading equipment that are accurate to meet the target of overburden stripping production. Then, analysis and efforts to reduce loss time were made to achieve a total production of overburden stripping of 58,059.52 bcm/month. This means that the planned production target of 43,700 bcm/month was met and even exceeded, with the OEE value of each digger being 26%. and 22%. However, the OEE value is still relatively low compared to the standard world-class OEE value, which is 85%.

Abstract

PT Mandiangin Batubara targets overburden stripping production in June 2022 of 184,571 bcm in the highwall bottom area of pit A, while for the realization of the ability of the SANY SY500H Excavator, the resulting production is only 121,347 bcm / month. The non-achievement is also due to the low effective working time which is only 367.76 hours / month and 358.74 hours / month from the available time of 641 hours / month.Efforts that can be made to analyze based on the problem are in the form of analysis using the overall equipment effectiveness method and determining losses based on the six big losses of equipment. Then proceed with grouping the root cause of the problem of non-achievement of production, namely with the Fishbone diagram. From the results of the analysis based on the six big losses, it was obtained that the highest losses occurred in Equipment Failure Losses of 42.62% and 44.03% respectively. After repairing the loss time, the total production of Overburden stripping was 221,925 bcm which means that the results of these improvements can exceed the production target by increasing the OEE value of the digging and loading equipment by 48% and 54% respectively.

Abstract

South Pariaman Subdistrict, Pariaman City has abundant iron sand mineral resources. However, the use of iron sand in the area is still less than optimal because the local government and local communities do not have data on iron sand exploration in the area. Mineral resources are mineral deposits that are expected to be utilized in real terms. Mining resources with certain geological beliefs can change into reserves after a mine feasibility assessment is carried out and meets the criteria. The purpose of this study is to determine the distribution of iron sand in the study area, the value of the percentage of magnetism, the percentage of magnetic mineral value. There are 21 borehole points with a depth of 0-2 m. From this research, several results were obtained, including from the borehole lithology process, it was known that the material contained varied from medium sand with a size of 0.25-0.55mm and fine sand with a size of 0.125-0.25mm. After preparing the sample, the largest percentage of magnetism (MD) was obtained at point 17 of 26.36% and the smallest percentage at point 20 of 6.04%. The largest percentage of magnetic minerals (MM) at point 17 was obtained at point 17 at 30.85% and the smallest percentage at point 20 was 7.61%. From the magnetic percentage value and the percentage of magnetic mineral value, a magnetic percentage value distribution map and magnetic mineral distribution map were made using the Inverse Distance Weighted (IDW) method which shows that the value of the distribution of iron sand in the part leading to the ocean is greater than in other areas.

Abstract

Production at PT. Bima Putra Abadi Citranusa, especially in the 4th quarter of 2021, has not yet reached the production target for both overburden stripping and coal getting. The production target was not achieved because the mining stage design at the company had not been maximized. For this reason, it is necessary to plan a mining sequence in the first quarter of 2022 to catch up with the production target. Data processing was carried out using the Minescape 5.7 software and Microsoft Office 2019. The result was a stripping ratio of 3.87 in the first quarter of 2022 with a plan for mining stages to be carried out mostly on the low wall section so that as much as 2,361,610 BCM of overburden can be produced. coal 609,840.23 tons. The digging equipment used is the Caterpillar 345 EXCZ Excavator, the Doosan 520 EXZ Excavator and the Doosan 800 EXCZ Excavator while the transport equipment used is the Hino 500 DTB dump truck, Mercy Axor DTMB, Hino 700 DTM and Terex TR50D.
