Abstract

Kejadian kegempaan di pulau Sulawesi diamati selama 2008-2018 oleh Badan Meteorologi Klimatologi dan Geofisika tercatat sebesar 800 kejadian dengan magnitudo  > 4 Mw. Dilakukan analisa berdasarkan peta persebaran kegempaan untuk mengetahui aktifitas seismik secara kualitatif daerah-daerah di wilayah Sulawesi. Tingkat kerawanan ditentukan berdasarkan frekuensi kejadian dan magnitudonya. Data dipetakan menggunakan Generic Mapping Tools dan diklasifikasikan berdasarkan besarnya magnitudo momen. Berdasarkan pemetaan, didapatkan bahwasanya konsentrasi kegempaan terjadi di wilayah tengah dan utara Sulawesi untuk kejadian di daratan. Kemudian berdasarkan cross correlation diinterpretasikan bahwa terdapat pengelompokan kejadian pada wilayah-wilayah tertentu yang diyakini sebagai jalur patahan, dan sangat dibutuhkan kajian lebih mendalam.

Abstract

The Environment and Forestry Metrics stated that data on waste piles in Indonesia in 2020 reached 67.8 tons, 45% of which was poorly managed plastic waste. The large amount of waste produced causes Indonesia to become the second waste producer in the world. The level of waste management that is still minimal is the main thing that causes Indonesia to become a "polluting" country in the world. Waste Power Plant is a waste management solution to reduce the amount of waste and become an alternative energy for generating electricity in the community. The purpose of this research is to provide an alternative by creating a waste power plant as a producer of renewable electrical energy. This research begins with collecting materials and continues with the design of components such as furnaces, boilers, steam turbines, DC generators which are integrated into one, and waste as fuel. The components that have been worked are then tested with plastic waste and wood waste are collected and then put into the furnace, then the waste is burned to boil water in the boiler. Changes in the speed or relative velocity of this steam cause a force turns the turbine. The turbine that is connected to this generator will then rotate the generator to produce electricity. Based on the results of testing the solid waste power plant, the maximum voltage value is 13.76 V.

Abstract

Determination of the source of the earthquake has been carried out in the north arm of Sulawesi. The earthquakes analyzed were a local earthquake with a magnitude of more than 5 M. The source of the earthquake is the main variable in earthquake disaster mitigation. Determining the source of the earthquake using the arrival time of the P/S wave. The arrival times of the P/S waves were validated with a Wadati’s chart to test the convergence of the data. Determination of the source of the earthquake was analyzed using HYPOINVERSE. The source of the earthquake obtained has variations in depth and position. Comparison with the catalog shows a significant difference.
