Abstract

Telah dilakukan kegiatan pengabdian masyarakat yang bersifat insidental berupa “pendampingan teknis dalam mengimpleentasikan pendekatan saintfik  mata pelajaran IPA   SMP di Kabupaten Agam selama 3 bulan (Agustus-Nopember 2021) yang bertujuan untuk 1) meningkatkan kemampuan guru dalam melaksanakan standar proses kurikulum 2013 dan tujuan sampingan ; 2) mendiskripsikan faktor-faktor yang mempengaruhi proses implementasi kurikulum tersebut pada mata pelajaran IPA pada SMP N di Kabupaten Agam.Hasil evaluasi kegiatan pendampingan menunjukkan bahwa a) rata-rata kualitas perangkat pembelajaran yang disiapkan guru berada pada kondisi tersedia, tetapi belum lengkap terutama berkenaan dengan komponen RPP, media dan sumber belajar, aspek evaluasi, instrument evaluasi, dan bahan ajar b) pendekatan saintifik telah terlaksana tapi tidak sempurna, c) penguasaan konten dan kualitas persiapan pembelajaran guru masih rendah, d) pelaksanaan pembelajaran IPA pada umumnya masih dipisah antara IPA Fisika dan IPA Biologi, dan e) pendapat informan tentang permasalahan IPA berasal dari beberapa faktor terutama, yaitu masih rendahnya kompetensi guru, dan kurangnya fasilitas pendukung kurikulum. Kata kunci : implementasi, pendekatan saintifik, keterpaduan, pelajaran IPA

Abstract

Abstract. PT.Rajawali Internusa is a mining company engaged in mining contractor, PT.Rajawali Internusa uses the open pit method, therefore water is one of the things that greatly affects production activities. From the results of the analysis of rainfall data in 2011–2020 with a mine opening pit of 11.6Ha, a runoff discharge of 3.403/second was obtained. From drill log data, it can be known the cross section of geology, hydrogeology and fence diagrams as well as the determination of the K value, in terms of the discharge of groundwater entering the Pit by 1.5411/second. It takes a sump to hold water of 409,027.2/day. The total head of the pump that must be provided to drain water as planned is 30,712m, with a pump power of 21,679watts, then the pump needs can be calculated by comparing the runoff volume with the pumping volume with the addition of 5 pumps. Open channel design is known to be the width of the channel base 1m, hydraulic depth 1.5m, the length of the channel slope 1.74m, the topsurface width 2.74m and the channel guard height 0.86m obtained an open channel discharge of 1.186/sec so that it is able to accommodate the pumping water discharge.  Keywords: Rainfall, Ground Water, Sump, Pump, Open Channe.

Abstract

PT. Nusa Alam Lestari is an underground coal mining company located in Salak Village, Talawi District, Sawahlunto City, West Sumatra. Ventilation system on hole BT 03 PT. Nusa Alam Lestari uses a blowing system. This study aims to evaluate the quality and quantity of underground mining based on Ministerial Decree No. 555.K/26/M.PE/1995 with the parameters to be measured including the value of effective temperature, relative humidity, gas content, air requirements for tools, workers and equipment. gas control and measure the speed of the air flowing to get the value of the incoming air discharge. At hole BT 03 there are two forward fronts and six active mining branches. The results of the average temperature measurement on all working fronts of the BT 03 hole are 29.20C and the results of the average humidity measurement are 89.6%. This temperature value has passed the threshold set between 180C-270C and the humidity has also passed the set threshold of 85%. From the results of the calculation of the air quantity, it is also known that the incoming air has a discharge of 2.83 m3/s. In fact, the need for air which includes the need for air for workers, the need for equipment air, and the need for diluting methane gas is 5.0546 m3/s. Based on the situation the ventilation design for the future is to make a through hole from the C8 branch to the surface. In addition, it will also be equipped with a suction blower system. The simulation results using the Ventsim software stated that the intake air flow rate increased to 12.6 m3/s and has met the total air requirement standard. Furthermore, in the design of air ventilation for mining activities for the next 12 months, it is known that the total mining progress is 2345.3 m per year and the production target is 1334 tons per month. To meet the demand for air, a 20-inch centrifugal blower will be used in each hole A and B and 12 axial blowers will be used to help air reach the work front at each branch.

Abstract

Abstract. The volume and tonnage of stockwash at the Bauxite Processing Plant have a great influence on the achievement of the company's production targets, so it is necessary to carry out good monitoring so that the loss of material in the stockwash can be minimized. Material loss can occur in the process, transportation and washing as well as the process of stacking material in the stockwash. Material that has been stacked on the stockwash can also be one of the factors for the occurrence of material loss, another factor is the uncertainty of the material production calculation data that has been washed in the field. So to ensure its production for that it is necessary to carry out laboratory analysis. Based on the calculation results that have been carried out, the difference between stock balance CF 50% and stock balance from laboratory analysis at Bauxite Processing Plant 1 and 2 is 3.389,05 tons. Based on the comparison chart, the results of the stock balance calculation from the laboratory analysis look more accurate when compared to the calculation of stock balance data truck count CF 50%. Keywords : Bauksit, Tonase, Lose material.

Abstract

PT. Karya Usaha Aneka Tambang Solok Selatan Indonesia is a company engaged in iron ore mining in Danau Kembar District, Solok Regency, West Sumatra with a mining business permit area of 31 hectares. PT. Karya Usaha Aneka Tambang Solok Selatan Indonesia has carried out further exploration and drilled 11 drill holes. This study has purpose to modeling, analyzing, and validating estimation method used for the assessment of iron ore resources at PT. Karya Usaha Aneka Tambang Solok Selatan Indonesia. The method used in this research is Inverse Distance Weighted (IDW) and Ordinary Kriging (OK) using Surpac 6.5.1 software. The block model made with the size of the model block units is 5x5x1 meter. The accuracy of the two methods in the assessment will be compared using downhole composite validation. In this study, the data used is data from detailed exploration drill activities of 11 drill holes with 254 composite data. From the results of the study, the estimation of the IDW method was obtained from all resources, namely 524,115 tons with a volume of 137,925 m3 and an average Fe content of 37.50%. And for the OK method estimation, the amount of all resources is 288,990 tons with a volume of 76,050 m3 and an average Fe content of 37.50%. Based on the validation using the composite downhole of each method, the IDW method gets results that are closest to the composite value and get a value that is greater than the OK method. So the volume that will be used in various decision making for the purposes of further exploration, mine planning and other technical matters is the volume of the IDW method.

Abstract

A good haul road is a road that can make the haul equipment run optimally. Distance from the front loading pit 2 area to the stockpile is 440 meters which consists of 4 segments. This research will analyze the condition of the Loading Point haul road to the current stockpile in each segment, make an improvement plan so that the haul road condition conforms to predetermined standards, analyze the effect of improving haul road geometry on the travel speed of the Mitsubishi Fuso 220 PS, and analyze the effect of improving haul road geometry on the productivity of the Mitsubishi Fuso 220 PS conveyance. With the haul road analysis, it is known that there is a need to improve the geometry of the haul road on a straight road with an ideal width of 4.92 meters, a bend road of 7.35 meters, the formation of a cross slope of 40 mm/m, making a superelevation so that the height difference that must be made is 0 .29 meters, and the need for haul road pavement. Through these improvements, with a coal production target of 5,000 tons/month, it is known theoretically that productivity from 125.66 tons/hour has increased to 186.92 tons/hour.
