Abstract

Abstract. In mining activities with hard rock characteristics, it is necessary to do a blasting which aims to clean the rock, so that it can facilitate digging. The size of fragmentation as a result of blasting will affect to the digging time, the greater of the fragmentation that results will be the longer the time needed to digging the blasting material. Blasting geometry applied by PT. Semen Padang produces fragmentation measuring 53,86 cm with digging time of 14,29 seconds. In this study Blasting Geometry was used with ICI-explosive and RL. Ash theories. Where the fragmentation produced by the ICI-Explosive Theory is 47,86 cm with the digging time of 11,15 seconds, and with the Theory of RL. Ash fragmentation obtained is 43.71 cm with digging time of 8,6 seconds. Of the two theories, the theory of RL. Ash is better because it produces better   fragmentation.Keywords:  Blasting Geometry, Fragmentation, Digging Time, Kuz-Ram, Regression Analysis

Abstract

PT. Semen Padang is one of the greats cement producer industry in Indonesia. PT. Semen Padang has a mining business license for limestone mining at Bukit Karang Putih – Indarung, Padang City, West Sumatera. For getting limestone, PT. Semen Padang used quarry mine system and blasting technique in separating limestone from rock body.In blasting, one of success variable can be viewed from the size of fragmentation and rock uniform level. Size of fragmentation and rock uniform level can be expected with good blast geometry plan. Will be obtained good rock fragmentation, and good uniform level. From the geometry of the blasting used in PT Semen Padang, obtained rock size fragmentation up from 120 cm percentage is 7,84 % with rock uniform level 1,47 and the volume of rock explosed 126 m3 from one blast hole. The percentage of rock filtered is quite good. However, it’s not followed by rock uniform level and rock explosed volume. So that, need for changes blast geometry with ICI – Explosive Method for getting good fragmentation size, good rock uniform level and large rock explosed volume.After calculated and experimented in the site. The most suitable blast geometry is 5 m for spacing and 4 m for burden. So, we can get 210 m3 limestone from one blast hole, with size of rock fragmentation up from 120 cm is 20,92 %, and rock uniform level 1,26. Therefore, will have the impact on increasing the limestones product and rock uniform level better.

Abstract

TPAS Ampang Kualo is the final dumping place in Solok city of West Sumatra which is located near the residential area. Garbage accumulation in TPAS Ampang Kualo resulted in environmental pollution, therefore it is necessary to conduct research on TPAS Ampang Kualo with the aim to know the distribution of its waste. Estimation of the distribution of waste below the surface of the soil can be done by using the geolistrik type resistance method. Data retrieval with MAE X612 EM Resistivity meter using geoelectric method of resistance of configuration type Wenner - Schlumberger. The measurement data is then inverted using Res2dinv software to bring up the 2D resistivity profile and the Voxler 4.0 software for 3D resistivity profiles. The results showed that the leachate water of TPAS Ampang Kualo was almost evenly distributed. On Track one is around a leachate pond stretching from South to North, Lindi is detected from a range of 5 meters to 42 meters with a depth of 2.10 to 5.80 meters. On Track 2 also around a leachate pond stretching from East to West, Lindi is detected from a stretch of 7 meters to 44 meters with a depth of 1.50 to 6.35 meters. At Trajectory 3 is in the vicinity of a residential population stretching from South to North that cuts off the flow of leachate ditches, Lindi is detected from a 1 meter to 31 meter stretch with depths of 0.25 to 7.38 meters.Based on the results of the research and geological map in the area, point to the research area at TPAS Ampang Kualo subsurface layer composed of rocks and minerals, ie, clay, sand, gravel, and quartzite igneous rock.It was concluded that the distribution of waste at the TPAS Ampang Kualo to the south to the southwest followed the small flow of leachate discharge, due to the lower topography of the TPAS and the distribution of its waste also to the vicinity of Green Hills Arya housing.

Abstract

Jagung merupakan salah satu komoditi unggulan Desa Kampung TangahKecamatan Lubuk Basung, dimana produksi jagung dari tahun ketahun mengalamipeningkatan. Dari setiap panen jagung diperkirakan jagung (rendemen) yang dihasilkansekitar 65%, sementara 35% dalam bentuk limbah berupa batang, daun, kulit, dan tongkoljagung (Anonimous, 2003). Tingginya produksi jagung tiap tahunnya berdampak padatingginya limbah yang dihasilkan terutama limbah tongkol jagung. Limbah yangdihasilkan pasca panen jagung ini yang paling mudah dan bisa dilakukan petani untukmenangani limbah tersebut adalah dengan membakarnya. Dari pengamatan lapanganditemukan bahwa tongkol jagung tidak termanfaatkan dan dibuang atau dibakar.Diketahui bahwa dari tongkol jagung yang dihasilkan sangat kaya akan karbohidrat yangdapat digunakan atau diolah menjadi produk yang bermanfaat dan bernilai ekonomiuntuk kehidupan manusia. Dengan pemanfaatan teknologi, sebenarnya limbah tongkoljagung tersebut bisa dikembangkan menjadi suatu produk yang lebih bernilai ekonomiyaitu diantaranya dijadikan sebagai briket.Kegiatan yang akan dilakukan ini dapat dijadikan sebagai alternatif pemecahanmasalah dalam mencapai tujuan serta harapan masyarakat tentang pemanfaatan limbahkhususnya tongkol jagung dan sejalan dengan tujuan dari program pengabdian denganmerangkul kelompok masyarakat supaya terciptanya lingkungan, kualitas hidup yangsehat dan menjadi desa energi. Pada program ini akan memberdayakan 2 kelompoktani yaitu Kelompok Tani Harapan dan Kelompok Tani Bangkit yang merupakan petanijagung yang hasil jagungnya dijual untuk diolah menjadi makanan ternak. Biasanya sisatongkol jagung yang telah diambil jagungnya mereka buang dan dibakar begitu saja.Padahal tonggol jagung ini bisa diolah untuk menjadikan briket yang mempunyai dayajual. Oleh karena itu tim pengabdian tertarik melakukan pengabdian di bidang ProgramKemitraan Masyarakat dengan judul “Produksi Briket Arang dengan PemanfaatanLimbah Tongkol Jagung di Desa Kampung Tangah Kecamatan Lubuk Basung”..Kegiatan yang akan dilakukan adalah bagaimana memproses tongkoljagung yang biasanya dibuang sampai menjadi briket yang mempunyai daya jual. inidimulai dari bagai mana proses mulai dari bagaimana mengolah tongkol jagung sampaimembuat alat dengan output berupa briket sebagai energi, dan dalam pelaksananya dalamwaktu 8 bulan dengan survey awal ke lapangan, melakukan pertemuan/diskusidilanjutkan pengambilan data serta kesepakatan dengan mitra. Tim pengabdian optimisdengan pelaksanaanya nantinya dapat memberikan apresiasi dan inovasi baru bagimasyarakat dan pemerintah daerah. Pada dasarnya kegiatan yang akan dilakukan ini akanmemberikan multi efek bagi masyarakat sekitar dan untuk pemerintah daerah dalammewujudkan desa energi dalam pemerintahanya.

Abstract. Determination of the mining geometry in the room and pillar underground mining method is a fairly complex job. This research was conducted by analyzing the stress on the coal pillar and the coal pillar strength to obtain its safety faktor. Stress determination on the pillars is calculated based on the theory of tributary area loading with the stress working on the pillars is 6.775 MPa. Meanwhile, the coal pillar strength is obtained using empirical equations with the pillar strength of 17.6 MPa. Thus, the pillar safety faktor based on analytical calculations is 2.62 (stable) with mining recovery around 40%. Rock mass characterization is carried out based on rock mass classification Rock Mass Rating (RMR) System. The value of the RMR for coal is 56, where this rock is included in class III rock with a stand up time recommendation for 580 hours and maximum span 6.5 m. Modeling using Phase2 shows the direction of stress transfer tends to be centered on the mining blok area with average mean stress 4.2 MPa and strength factor 2.53. Evaluation of mining geometry is obtained through simulation calculations for several pillar sizes with the results in the form of recommendations for the ideal pillar dimensions 7 m x 7 m with estimated recovery around 55% and safety faktor 1.53.Keywords:  Pillar Dimensions, Tributary Area, Safety Faktor, Recovery, RMR System

Abstract

Mining activities at PT Indocement Tunggal Prakarsa use the Quarry method and the process of dismantling the limestone material using blasting methods to meet the production targets and facilitate the loading and hauling process. Each blast requires a fragmentation size ≥ 90 cm of ≤ 5% and a ground vibration that fits the target of the company. However, the reality of the field found that the size of fragmentation does not exceed the target desired by the company because the size of ≥ 90 cm fragmentation of ± 11%. Improvements in blasting activities need to be done to obtain the size of the target fragmentation by the company. Therefore, one of the way to obtain the size of the target fragmentation is using the double deck primer methods by putting two primers in the bottom and in the centre of the blasting hole with stemming in the centre of the hole for minimalize the ANFO. The method resulting the same energy in all part of the hole and finally minimalize the boulder. The methods that are used to analyze fragmentation of explosive results in this research are theoretically by using Kuz-Ram method and image analysis method by using Split Desktop Software. This is done to determine the percentage of fragmentation of blasting results and take into account the boulder. The results of fragmentation analysis of the blasting results show that the addition of Double deck primer may affect the size of fragmentation. The sizes of fragmentation are ≥ 90 cm (boulder) to 2,27% and ground vibration at <2 mm / s so the size target of fragmentation that is desired by the company is achieved and the value of ground’s vibration  is under the value set by the company.Keywords:  Blasting, Fragmentation, Vibration, Cost

Abstract

ABSTRACT PT. Semen Padang is a national cement company which owned IUP of limestone mining at Bukit Karang Putih, Indarung, Padang-West Sumatera. Limestone is the main composition of cement making.    PT. Semen Padang use quarry system in the limestone mining activity at Bukit Karang Putih. Limestone production accomplished by blast activity. The quality of blasting result really determine  the success of blast activity. The success parameter of blasting is the fragmentation of resulting  stone.Stone fragmentation evaluation can be done by noticed the blasting geometry. According to today actual blasting geometry, the fragmentation of stone with >100 cm size is 19 % (calculated using Software Split Desktop 3.1). It means that the fragmentation of stone resulting  <100 cm is not optimum,  so,  replan the blasting geometry design in order to optimize the distribution of blasting fragmentation by using R. L. Ash (desain I), ICI-Explosive formulation (design II) and the combination of ICI-Explosive formulation by fitting the field condition(design III).According to the calculation of actual fragmentation using Software Split Desktop, then design II  of blasting geometry is choosen. Based on the fragmentation  percentage of stone with >100 cm, geometry design II (0 %) compare with geometry design III (4 %), however, based on the flying rock resulting from blasting, geometry design III is recommended to be set as a new design. According to the change of the geometry, the fragmentation reduction of stone resulting from blasting >100 cm is 15 %.  Keyword: Blasting Geometry Desain, Limestone Fragmentation. ABSTRAK PT. Semen Padang merupakan perusahaan semen nasional yang memiliki IUP Penambangan batu kapur di Bukit Karang Putih, Indarung, Padang - Sumatera Barat. Batu kapur merupakan bahan baku utama untuk pembuatan semen. Kegiatan penambangan batu kapur di Bukit Karang Putih oleh PT. Semen Padang dilakukan dengan sistem quarry. Kegiatan produksi batu kapur dilakukan dengan kegiatan peledakan. Kualitas dari hasil peledakan peledakan sangat menentukan keberhasilan kegiatan peledakan. Parameter keberhasilan dari suatu kegiatan peledakan adalah fragmentasi batuan hasil peledakan.Evaluasi fragmentasi batuan hasil peledakan dapat dilakukan dengan memperhatikan geometri peledakan. Berdasarkan geometri peledakan aktual saat ini, didapatkan fragmentasi batuan yang berukuran >100 cm sebesar 19 % (perhitungan menggunakan Software Split Desktop 3.1). Hal ini menunjukkan fragmentasi batuan hasil peledakan <100 cm belum optimum. Selanjutnya dilakukan perencanaan ulang geometri peledakan untuk mengoptimumkan distribusi fragmentasi peledakan dengan rumusan R. L Ash (desain usulan I), ICI-Explosive (desain usulan II) dan kombinasi rumusan ICI-Explosive dengan penyesuaian kondisi lapangan (desain usulan III).Berdasarkan hasil perhitungan fragmentasi aktual menggunakan Software Split Desktop, maka dipilih geometri peledakan usulan III. Dari segi persentase fragmentasi batuan berukuran >100 cm, geometri usulan II (0 %) dibandingkan dengan geometri usulan III (4 %), akan tetapi dari segi lemparan batuan hasil peledakan (flying rock) geometri usulan III lebih direkomendasikan untuk ditetapkan menjadi desain baru. Dari perubahan geometri tersebut, didapatkan penurunan fragmentasi batuan hasil peledakan >100 cm sebesar 15 % . Kata Kunci: Desain Geometri Peledakan, Fragmentasi Batu Kapur.

Abstract. PT Semen Padang plans to commission their new cement factory, Indarung VI, which increases monthly demands for limestone and silica stone (supplied by existing Mine Area of Bukit Karang Putih) to 1.117.781 tones and 156.773 tones. This research is purposed to get the capability of production equipment (loaders, trucks, crushers, belt conveyors) in existing area to match production targets and to determine what kind of optimization is needed to make the equipment capable to fulfil the target. We approach this research by using a simulation that build based on actual conditions (operation pattern, effective working hours, and productivity), then comparing the result to the production targets. Optimizations are determined by analyzing effective hours and productivity of each equipment, then compare them to the theoretical ones. From the simulation, equipment in existing area has actual production of 674.503 tones limestone, and 81.960 ton silicastone, only 60% and 52% of the production targets. Therefore, optimization needs to be done. Optimization is doing by: improving the work efficiency from 69,90% to 86,11%; recalculate matching fleet; and adding two extra shifts per day. After implementing optimization into simulation, equipment in existing area finally, match production target, by producing 1.133.487 tones limestone and 162.471 tones silica stone.Keywords:  Commissioning; Simulation; Optimization; Effective Hours; Productivity
