ABSTRAKPulau Sumatera terletak di antara dua lempeng tektonik yaitu lempeng Indo-Australia dan lempeng Eurasia. Intensitas gempa bumi sangat besar di pulau ini, terutama di sepanjang daerah pesisir barat. Pada 2002-2008 periode, banyak gempa bumi besar yang menyebabkan korban jiwa dan kerusakan lingkungan. Fenomena ini menunjukkan bahwa studi tentang pola deformasi pulau Sumatera sangat diperlukan. Studi yang diperlukan adalah untuk rencana mitigasi bencana di masa depan. Pola deformasi gempa dapat diamati dengan GPS pengamatan (Global Positioning System). Data yang digunakan untuk gempa Sumatera adalah GPS Sumatera Array (SuGAr). Perangkat lunak yang digunakan untuk data Array GPS Sumatera dari pulau Sumatera adalah Gamit 10.4. Dari hasil pengolahan data, dapat disimpulkan bahwa data perpindahan koordinat stasiun dapat digunakan jika data outlier telah terhapus. Dari koordinat perpindahan stasiun bisa diperoleh vektor perpindahan semua stasiun sebelum, selama atau setelah gempa bumi. Dari perpindahan nilai-nilai vektor, nilai regangan yang terjadi di sepanjang pulau Sumatera dapat diperkirakan. Dari data regangan, nilai akumulasi regangan 2002-2008 dapat diperoleh. Sehingga dapat dianalisis wilayah yang berpotensi terjadinya gempa selanjutnya.Kata Kunci: Akumulasi Regangan , Deformasi, Kerusakan Lingkungan, ABSTRACTThe Sumatra Island is located between two tectonic plates; the Indo-Australia Plate and the Eurasian plate. The intensity of the earthquakes is very large on the island because of this, especially along the western coastal area. On the 2002 to 2008 period, many large earthquakes that caused casualties and damage to the environment. These phenomena shows that the studies of the deformation patterns of the Sumatra island is required. The studies are required for disaster mitigation plans in the future. The deformation patterns of the earthquake can be observed with GPS (Global Positioning System) observation. The data that is being used for Sumatra earthquake is the Sumatran GPS Array. The software that is used for the Sumatran GPS Array data of the Sumatra Island is the Gamit 10.4. From the data processing, it can be concluded that there are displacements of the nations can be used if the outlier data has been erased. From the station displacement coordinates, we can obtain the displacement vector of all of the station before, during or after the earthquakes. From the displacement vector values, the values of the strain that occurs along the Sumatra Island can be estimated. From the strain data, the accumulated value of strain from 2002 to 2008 can be obtained. Finally it can be predicted potential area for next earthquake.Keywords: Keywords: Deformation, Environmental Damage, Accumulated Strain.

Abstract. Based on observations that have been made on the Mandeh-Nyalo Tourism Area road section, it is found that the slopes which have many weak field structures in the form of burly, and the high intensity of the earthquake in West Sumatra greatly affect the stability of the slope conditions. From these problems, it is necessary to know the condition of rock mass on the study slope. Furthermore, it is necessary to analyze the slope stability. From the results of rock mass classification with the RMR system, the rocks are included in group II with good quality rock mass. Then, from the slope stability analysis using slide software, the slope stability value in the original condition was 1.95 and the saturation condition was 1.36. And based on the analysis of the slope stability value with the Hoek and Bray method, the slope stability value is 1.70.Keywords: Slope, landslides, rock mass, safety factors, strengthened

Abstract. West Sumatra is a province located in an earthquake area. West Sumatra is located between the Eurasian Plate and Indo Australian plates. From 2002 until 2009, there were many earthquakes in the Sumatra region. In 2009 there was a major earthquake it caused many people dead, environmental damage and material losses in the West Sumatra. This is the reason for deformation studies in West Sumatra. The focus of the deformation study needed in West Sumatra is to mitigate future disasters. This deformation measurement is done by Geodetic GPS . The Geodetic GPS measurement data results are obtained from the Sumatra Array GPS data (SuGAr). The Geodetic GPS Measurement Data is then processed using software Gamit 10.5. From the results of data processing, there was accumulation of strains in 2002-2008 along the coast of central Sumatra which has the potential for earthquakes. And in 2009 on September 30 there was an earthquake that could be seen by a significant change in position during the pastoral era in the West Sumatra region. By studying as early as possible deformation in West Sumatra, it is expected that in the future the risk of environmental damage and losses due to earthquake disasters can be minimized.Keywords: Deformation, Environmental Damage, Earthquakes

Abstrack Based on the production data limestone minning at existing area of PT. Semen Padang in January-February 2018, limestone mining production did not reach the target. This is due to the low productivity of the dumptruck. To find out the improvement potential of a production process and the effectiveness of using equipment, it is necessary to do an analysis using the Quality Control Circle (QCC) method. After knowing the root of the problem, ideas for improvement are given to obstacles so that production can be achieved. After doing the analysis and improvement with these methods, the production of the komatsu HD 785-7 dumptruck exceeded the planned target. However, for the values of PA, MA, UA and EU, each conveyance is still < 85% has not yet reached the optimal world class value that is > 85%, it can be concluded that the condition of the equipment is not good. It is better to do repairs to standby time and tool breakdown. Keywords: Production, Quality Control Circle, Pareto Diagram, Fishbone Method, komatsu hd 785-7 dumptruck

PT. Budi Gema Gempita is one of the coal mining companies operating in East Merapi District, Lahat Regency, South Sumatra. The mining system used is an open pit mining system using the Open Pit Mining method. In carrying out mining operations, there are differences in production results from the data recorded by the checker in the form of truck count data and survey data. The results of the calculation of the volume of overburden material based on survey data obtained a comparison of overburden volume based on survey data and truck count data in June 2021 in the East Section 2 pit on the first week 12,574.22 bcm, second week 28,507.03 bcm, third week 16,415.47 bcm and fourth week 53,958.90 bcm.Due to the difference in the volume of survey data with truck count data, in the conclusion with actual condition of the truck count data in the form of overburden material that is sticky on the vessel dump truck or articulated dump truck being transported back to disposal because the type of material transported is in the form of mud (material containing water), making it difficult to stockpile. Meanwhile, by looking at the survey measurement conditions, there is a fill value that has not been transported to disposal, which is measured again in the survey measurement so that it reduces the cut value.

Kota Sawahlunto memiliki banyak potensi bentang alam karst. Salah satunya adalah Gua Janjian yang terletak di Desa Talago Gunung, Kecamatan Barangin. Pemetaan adalah tahap pertama untuk melihat kondisi gua dan identifikasi objek di dalam gua. Pemetaan pengukuran menggunakan alat bantu seperti kompas, klinometer, pita ukur dan distometer. Metode yang digunakan dalam pemetaan ini adalah metode offset. Pengukuran menggunakan satu titik referensi atau stasiun dari pengamatan GPS. Dari data sudut horizontal, sudut vertikal, dan informasi jarak dapat diperoleh nilai posisi x, y dan z titik pengamatan yang diambil dari referensi stasiun. Penampang goa dilakukan dengan mengukur jarak ke kiri dan kanan goa, atap dan lantai goa pada titik stasiun pengamatan. Hasil pemetaan ini adalah peta Gua Janjian dan sebaran speleotema. Dari penelitian ini diharapkan dapat menjadi tahap awal konservasi karst di Gua Janjian.
