Abstract

The crushing plant in the mining industry produces noise levels above the allowable noise level, potentially causing hearing damage to mining workers. One way to early control this is by mapping the noise distribution in the area. The noise distribution mapping was based on noise intensity. The noise intensity measurement was done using a sound level meter according to Indonesian national standards 7231:2009. The noise exposure analysis was based on the NIOSH formula and Indonesia's national standard 7570:2023. The study's results revealed that noise levels at the source exhibited an intensity of approximately 95-103 dB. The noise propagation pattern extended from the southwest to the northeast, with an intensity of approximately 68-93 dB. The highest noise intensity was observed in the vicinity of the first jaw crusher, exceeding 100 dB, with a daily exposure time in this area of 6-12 minutes. Prolonged exposure to high noise levels can potentially lead to auditory damage. Therefore, the implementation of noise control measures, including using personal protective equipment and the installation of appropriate safety signage, is imperative.

Abstract

Soil (topsoil and overburden) above the granite quarry in pit 2 (two) PT. Karya Sumber Alam Perkasa has experienced a landslide. It is probably caused by the condition of pit 2 (two) slopes at PT. Karya Sumber Alam Perkasa, which is currently being mined, is quite steep. External factors that can trigger the movement of rock masses are vibrations due to breakers. This condition has the potential to increase the risk of slope stability. Slope stability is influenced by geological conditions, joints, slope geometry, water conditions below the soil surface, physical and mechanical properties, and vibrations due to blasting and mechanical equipment. Therefore, it is necessary to conduct a technical study of slope stability. The research aims to study rock mass class, potential type of landslide, and potential slope stability. The technical study of slope stability uses the Slope Mass Rating (SMR) method. Data processing using software Rocscience Dips 7.016. Analysis of potential types of landslides based on stereographic projections. The result of the RMR calculation is 78, so the rock mass class is number II, which is included in the excellent category. The results analysis of the potential for the type of failure indicates t tends to lead to the toppling failure, but after the study, there is no failure because it does not meet the landslide requirements. The result of the analysis of potential slope stability is that the slope in pit 2 (two) is safe or stable because the SMR value is 78 and the safety factor value is 2,458.

Abstract

Occupational safety and health aim to create a safe and comfortable environment in carrying out activities or work. In PT ANTAM's bauxite transportation activities, there are still occupational safety and health risks. The purpose of this study was to determine the frequency rate, accident severity (Severity Rate), and Safe T Score in PT ANTAM's bauxite transportation activities. The research method used is a descriptive method, which is a research method that describes quantitative data according to the conditions in the field of bauxite transportation activities. The results of the study are (1) The results of the calculation of the frequency rate of 0 which indicate that there were no mining accidents in bauxite transportation activities in January-September 2019; (2) The result of the calculation of the severity rate (Severity Rate) of the accident is 0 which indicates the absence of the severity of the mining accidents that resulted in that month due to the absence of mining accidents that occurred in that month; (3) The results of the calculation of the safe T-score of 0 indicate the work accident control program does not show a significant change.

Abstract

CV. Artha Agung Bersama is an andesite mining company that uses a blasting system. This mining activity can harm workers if they do not apply good K3 management in blasting activities. One of the hazards of blasting activity is flying rock. For this reason, it is necessary to identify potential hazards, assess the level of accident risk, and recommend risk control efforts. The method in this study is the HIRAC (hazard identification risk assessment and control) method. This activity has five potential hazards: broken drum straps, worker negligence, explosive sounds, fly rock, and workers walking in a hurry in locations with a lot of gravel. There are five risks of accidents from potential hazards: being hit by a drum, scratched hands, pinched fingers forming a critical cover, slipping, exposure to diesel fuel, hearing loss, and being hit by a rock. Of the five hazard risks, three risks are included in the priority one category, namely: scratched hands, pinched fingers forming key covers, slipping, exposure to diesel fuel, and being hit by rocks. One risk is included in priority category three: being hit by a drum. One risk category is very high, namely being hit by a rock. The recommended risk control hierarchy for blasting activities is engineering control, administration, and personal protective equipment.
