Abstract

Provinsi Aceh terletak diantara lempeng besar dunia yaitu lempeng Eurasia dan lempeng India-Australia serta sembilan lempeng kecil yang bertemu membentuk jalur-jalur pertemuan yang sangat kompleks. Akibatnya Provinsi Aceh merupakan zona tektonik yang sangat aktif. Tujuan penelitian ini untuk mengetahui nilai PGA (Peak Ground Acceleration) menggunakan metode mc. Guirre R.k dan Donovan serta mengetahui zonasi tingkat resiko kegempaan di wilayah Aceh. Penelitian ini dilakukan dengan titik koordinat 1˚-5˚ LS dan 95˚-98˚ BT. Data yang digunakan berasal dari USGS dengan magnitudo >5 dan kedalaman (0-70) km. Hasil penelitian yang di peroleh dari PGA (Peak Ground Acceleration) dari metode mc. Guirre R.K sebesar 153,288919 gal dan hasil penelitian dari metode Donovan sebesar 130,5759397 gal. Sedangkan zonasi percepatan tanah maksimum berada di wilayah Kabupaten Pidie Jaya. Pada wilayah tersebut terdapat endapan aluvium dan batuan berusia tersier yang bersifat lunak atau tidak kuat. Sehingga mengakibatkan wilayah tersebut rawan kegempaan.

Abstract

Leachate has the potential to be used as organic fertilizer because it contains high levels of minerals and organic matter. In the leachate there are several compounds, namely heavy metal compounds, salts, nitrogen compounds and various types of other organic matter. Leachate leachate also contains very fine suspended matter from the decomposition of microbes, usually consisting of Ca, Mg, Na, K, Fe, Chloride, Sulfate, Phosphate, Zn, Ni, CO2, H2O, N2, NH3, H2S, Organic acids , and H2. This study aims to find out how the subsurface layer in the Medan Marelan Falls Landfill area, the distribution of leachate in the Medan Marelan Falls Landfill. 1D resistivity measurements were only carried out in the Medan Marelan Falls TPA area. The geophysical method used in this study is the Schlumberger configuration. This research was conducted at three points along the 200 meter track. on line I is at a depth of 6.92 m with a resistivity value of 3.16 Ωm with a North to South flow direction. On track II it is at a depth of 1.15 m, 4.53 m, and 22.1 m with a resistivity value of 1.5 Ωm, 2.25 Ωm, and 5.05 Ωm respectively with the North to West flow direction. On track III it is at a depth of 1.19 m, 20.8 m, and 53.9 m with resistivity values of 1.54 Ωm, 3.51 Ωm, and 1.13 Ωm respectively with North to West flow direction. The distribution of leachate at the Medan Marelan Falls TPA which dominates is on track III marked with black to bluish color images.

Abstract

Gunung Sibualbuali adalah stratovolcano yang terletak di Sumatera bagian utara, Indonesia. Gunung ini memiliki dua fumarol di bagian selatan gunung. Kubah lava berasal dari transfer sesar Toru-Asik. Dan Gunung Sibualbuali terdiri dari aliran lahar andesit hingga dasit yang umumnya berumur Holosen. Penelitian bertujuan untuk menginterpretasikan struktur bawah permukaan di daerah panas bumi Sibual-buali Tapanuli Selatan dengan menggunakan metode gravity. Manifestasi yang muncul di permukaan antara lain bumi dan batu panas, batuan permukaan hitam seolah terbakar, dan beberapa fumarol di sekitar jalurnya. Dalam menginterpretasikan struktur bawah permukaan, juga diperoleh sebuah nilai deviasi setiap anomali mulai dari peta Complete Bouguer Anomali dengan nilai deviasi tertinggi sampai terendah berkisar 64 mGal sampai 112 mGal. Pada peta anomali regional diperoleh nilai deviasi tertinggi sampai terendah 66 mGal hingga 110 mGal. Dan pada nilai anomali residual dengan nilai deviasi tertinggi sampai terendah berkisar -0,1 mGal sampai 0,15 mGal. Nilai anomali yang tinggi di bagian barat menyebar ke bagian barat daya, selatan, tenggara, dan timur sehingga memungkinkan batuan dengan densitas tinggi dari kedalaman dalam hingga dangkal berasosiasi dengan batuan basalt. Dan lapisan ini merupakan lapisan batuan basalt yang manifestasinya berupa tanah panas dan batu panas serta fumarol

Abstract

Earthquakes are caused by the meeting of the two plates, namely the Indo-Australian plate and the Eurasian plate, the meeting of these two plates can also cause the occurrence of fault fault planes and subduction subduction with different depth levels. This study was conducted to see how the pattern of the fault fault plane and subduction subduction pattern that became one of the parameters to determine the depth of the epicentre after and before the relocation process, using the hypodd program format and ph2dt output results through anaconda prompt in the double difference method process, so that the results obtained from the relocation of the earthquake hypocenter in 196 earthquake events were only 127 earthquake events that could be relocated. Based on the relocation results using the double difference method, it can also be seen that earthquake events are more in the fault pattern with a depth level of 1-50 km, compared to the subduction pattern with a depth level of 60-200 km which is not too many earthquake hypocentres, so it can be said that the earthquake event in the North Sumatra region in 2023 is included in the shallow earthquake category.

Abstract

Household waste has become a significant cause of environmental issues. In addition to solid waste such as plastic, cardboard, and leftover food visible floating on the surface of rivers, large amounts of domestic liquid waste also contribute to river pollution. This has become a severe problem in many major cities in Indonesia, such as Medan, Surabaya, Bandung, Jakarta, and Palembang. Bandar Khalipah Village is among the areas in Medan where its river is starting to be polluted by detergent waste. The Islamic Boarding School was chosen to implement this activity because traditional boarding schools still require students to wash clothes independently. This activity aims to increase public understanding and awareness of the importance of environmental preservation by using environmentally friendly detergents. The stages carried out in implementing activities are the preparation, implementation, and program evaluation stages. The results indicate increased public knowledge about environmentally friendly detergents and active participation in implementing these practices at home. Before the socialization, 65% of participants needed help understanding the technique of making eco-detergent. After the socialization, a good level of understanding was achieved, with 95% of participants successfully mastering the technique of making eco-detergent. The implication is an increased awareness among the public about the importance of environmental conservation and reducing the negative impact of detergents on river ecosystems. Socialization and training programs can be concrete steps in overcoming environmental pollution problems at the local level. Through this effort, the community can continue to adopt sustainable practices to keep the surrounding environment clean and reduce the negative impacts of using conventional detergents.
