Abstract. Problems of environmental damage such as flood, garbage and drought in Indonesia is a problem that can not be solved. One of the things that cause problems to this flood is this is the decreasing of water absorption area and unconscious society not to throw garbage carelessly. Limited land in residential areas results in space for water catchment areas and few dumps. The purpose of this community service activity is to provide knowledge and skills to the community about the application of environmentally appropriate technology that is Biopori Absorption Hole technology (LRB). This activity is useful to increase the ground water reserves and reduce the waste as well as to produce compost. Partners of this activity are 2 groups of residents Rukun Tetangga (RT) that is RT 04 and RT 06 Village Tabing Banda Gadang, District Nanggalo, Padang. This form of activity consists of lectures and practices of making biopore infiltration holes. The practice of making the biopore infiltration hole involves community participation. Many of the created biopore holes are made up of 10 holes per each RT. The hole is 10 cm in diameter and 100 cm in depth. The holes that have been made therein incorporated organic waste in the form of remnants of vegetables, paper, fruit peels and others - others. Thus LRB is useful in reducing waste, increasing groundwater reserves, reducing the flow of surface water that causes flooding and will reduce the dangers of drought.

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

Abstract

Abstract. PT Sago Prima Pratama is a company engaged in the field of gold mining with an open mining system. Calculation and analysis of slope stability is very important to do, especially in open pit mining using the open pit method. Rock masses that were initially stable and undisturbed were dug up (disturbed) so that they could lose stability and cause landslides. If landslides occur, there will be hazards that disrupt the mining process so that production will be disrupted. From the calculation using Surpac software it is known that the pit depth is 150 meters from the ground surface. Movement often occurs on the slope, therefore slopes must be monitored so that movement on the slope can be known and can be known hazards on vulnerable slopes. Monitoring is usually done by looking at prism data. From these data we can see how much the slope is moving. With this monitoring can anticipate the potential for landslides early, so that treatment can be done earlier. Monitoring carried out at inpit has a range that ranges av. displacement at the study site during the August 14-29 2018 is 0.023mm to 0.177mm and the range av. instant velocity ranges from 0.30 - 1.33 mm / hour The fastest movement is at the BLS and the lowest is at the MSC.Keywords: Monitoring, slope, stable, displacement, velocity

Abstract. PT. Cahaya Bumi Perdana is a company engaged in the coal mining business in Sawahlunto City. Mining activities carried out are open pit mining system with replenishment method and underground mining system using space and pillar method. In August 2020 there was a landslide on the main road to the mining site. The type of slope forming material is clay. The assumed arc landslide stretch with the initial slope geometry before the landslide is 70 ° and 35 meters high. Landslides disrupt the main road access to the mine due to falling material. The method used in this research is the bishop method and the hoek and bray method. The results of this study can be ignored as follows. Data from laboratory testers were density 9,212 kN/m3 , cohesion 53,462 kN/m2 , and deep shear 22,950. The density value in dry conditions is 8,065 kN / m3, and at saturated conditions is 10,196 kN/m3 . The slope factor in natural conditions is 1.267, 1.372 in dry conditions, and 1.178 in saturated conditions. Recommended slope geometry using the bishop method with a new slope height of 17 meters, a width of 10 meters and a slope of 500 per level, and 420 for the total slope, obtained a new safety factor. The total safety factor in dry conditions is 2,223 and single slop is 3,031. In saturated conditions, the total is 1,932 and 2,546 singles. With the hoek method, the safety factor for new slopes in dry conditions is 2.49 and 1.93 in saturated conditions with the same height, width and slope as the bishop method.Key Words : Safety Factor, Bishop Metode, Slope.

Abstract

Based on the results of observations at BMK 35 CV. Bara Mitra Kencana, the authors conducted research on BMK 35 slopes where slope height (H) = 35 m and slope (a) = 65°. Referring to the description of the BMK 35 supervisor, in mid-2018 a large landslide occurred which resulted in tunnel 1 and tunnel 3 being completely buried. As a result of this incident, BMK 35 stopped producing for half a year due to road and tunnel access improvements. This incident occurred due to rainy weather at the mine site in mid-2018 and the absence of a good geotechnical design for the BMK 35 slope. Based on the data from the physical and mechanical properties of rock, the siltstone natural density was 22,84 KN / m³, the saturated density was 23,79 KN/m3, the dry density value was 20,17 KN / m3, cohesion (c) = 0.0419 Mpa and internal friction angle (ϕ) = 44,45°. In determining the value of the actual slope safety factor using software rocscience slide 6.0 with the janbu simplified method, the saturated condition slope safety factor value is 1,192, natural condition is 1,209 and dry condition is 1,265. So it can be concluded that the slope is unstable. The author provides two recommendations for slope improvement, namely, single slope and overall slope. Recommendations with a single slope is use a slope height of 35 meters, angle of slope 58° and get a FK 1,318 in natural conditions, 1,300 in saturated conditions, 1,375 in dry conditions. Recommendation overall slope is to divide into 2 single slope where each slopes have heights 17.5 meters and angle of the single slope is 65° and 51° for the overall slope. When in natural conditions, FK on a single slope is 1,559 and 1,403 for the overall slope. When conditions are saturated, FK on a single slope is 1,529 and 1,384 for the overall slope. When conditions are dry, FK on a single slope is 1,656 and 1,464 for the overall slope.
