Abstract. At PT. Cahaya Bumi Perdana, there is a slope with a height of about ± 30 m with a slope of 710 on the slope there are two types of slope-forming material that are in 1 bench, namely soil and rock material that is likely to occur landslides, with the slope conditions potentially endangering workers and hindering production. Based on the data from the physical and mechanical properties of sandstone rock, the original bulk density value was 8.024 KN / m3, the saturated weight value was 16.016 KN / m3, the dry weight value was 5.005 KN / m3, cohesion (c) = 0.0059 Mpa and the inner angle of shear. (ϕ) = 63,808 °. The analysis of the value of the safety factor (FK) and the recommendation of the actual slope geometry used the janbusimplified method with a height of 33m and a slope of 65˚ so that the FK obtained was 1.427. For geometric recommendations for slopes in a saturated state using the Janbu simplified method with a height of 33m and a slope of 65˚, the FK obtained is 1.317. From the value of the safety factor (FK) the recommendations obtained can be concluded that the slopes are stable.Keyword: Physical and Mechanical Properties of Rocks, Slope Geometry, Janbu Simplified, Safety Factors

Abstract. Based on observations made on the slopes in the THC 04 CV. Tahiti Coal, found rock slope which has a height of 30 meters, slope angle is 80° and has many weak plane structures that can cause landslides. Therefore it is necessary to analyze the rock mass and the stability of the slope. From the analysis that has been done, the rock mass classification value is 53, with medium quality and safety factor value at saturation condition is 1,141, original condition is 1,380, dry condition is 1,443. So it can be concluded that the slope condition is stable, except when saturated. Therefore, improvements need to be made in the form of reducing the slope angle to 66º and 67°, so that the value of the saturated slope safety factor changes to 1.256.Keywords: Open pit, slope, landslide, rock mass, safety factor.

Abstract. Natural disasters are disasters caused by the event or series of events due to nature. Natural disasters in recent years are very common and need preparedness, awareness and vigilance in the face of disaster, especially in the city of Solok, starting from earthquakes, landslides and so forth.Yet there is no socialization of natural disasters and disaster preparedness in SMA N 2 kota Solok so that students do not have the knowledge to mitigation and preparedness of natural disasters make the executor to conduct socialization mitigation and natural disaster preparedness to them.So that the participants in this case students understand about how to mitigate and preparedness natural disasters. The socialization is given in the form of lectures, discussions, and field practices.After the socialization was obtained increased knowledge about the mitigation of natural disasters by the students SMAN 2 Kota Solok. At pre-training (prior to training) only 71% of students who understand about mitigation and preparedness and at post-training increased to 100% of students understand the mitigation of natural disasters.Keywords: Disaster management Natural disasters, , mitigation and preparedness

PT. Bukit Asam – UPO is one of coal underground mining which conduct mine activity in Ombilin I (Sawahluwung), Ombilin II (Waringin-Sugar) and Ombilin III ( Sigalut). At underground mining, ventilation system is really important for human’s breathing need (worker), to netralize toxic gases, reduce ash concentration and control temperature . Ventilation system in Sawah Luwung underground mining used suction system with 32,76 m3/second air out quantity, while for air in is 32,33 m3/s through three in pit such as Adit Sawahluwung amount of 23,32 m3/s, Lurah Sapan I 6,81 m3/s and 2,28 m3/s in Lurah Sapan II. The difference of quantity of air in with air out is 0,43 m3/s which possible caused by adding air in in Mine Vein. The actual air temperature at work/production J14C front area is 26oC and 27oC for front J15C. Air Temperature decreasing is been done with two method such as putting ice in and out of thermos bottle. For thermos bottle trial it is conducted the number of air temperature decreasing in Front J15C is about 2,5oC – 3oC, while for front J14C is conducted 2oC – 2,5oC. Meanwhile without thermos bottle trial (putting ice in open section), temperature decreasing is 3oC – 3,5oC, and also 3oC in front J14. The result of air temperature decreasing between front J15C and J14C are different, which caused by the difference of duct length and the duct length in J15C is 15 meters and for J14C is 71 meters length. Based on this research, the tenacity of ice is 3 – 3,5 hours.

Spontaneous combustion problems are often almost ignored, one of which occurred in ROM stockpile at PT. Prima Dito Nusantara (PDN) which is an important issue in the coal mine. Some of the factors that cause the occurrence of spontaneous combustion at the company was the lack of stockpile management such as the length of the stockpiling of coal, compaction method of the coal piles on a less good, there has been no temperature measurement of the coal piles, and a lack of prevention efforts as well as handling against spontaneous combustion. To find out when the estimated occurrence of spontaneous combustion then do the measurement temperature of the coal pile periodically by measurement point temperature on compaction with Excavator and compaction with Bulldozer. Measurement results showed on compaction with Excavator faster occurs spontaneous combustion symptoms when compared with compaction with Bulldozer. Where in compacting with the Excavator can be estimated to occur in week-9 with highest median temperature 42,22°C, compacting with Bulldozer can be estimated in week-15 with highest median temperature 39,10°C. Therefore, compaction with Bulldozer better applied than compacting with Excavator to reduce the occurrence of symptoms of spontaneous combustion of the coal piles at ROM stockpile. Keywords: Spontaneous Combustion, Stockpile Management, Excavator, Bulldozer, Temperature.
