Abstract

Kepulauan Indonesia berada pada pertemuan tiga lempeng tektonik dunia dan banyak sesar-sesar aktif pada badan pulaunya sehingga rawan terhadap bahaya gempabumi. Saat ini sistem pemantauan gempabumi dilakukan oleh BMKG dengan menggunakan alat seismograf yang merekam gempabumi pada saat itu atau telah terjadi, akibatnya apabila terjadi gempabumi yang sangat besar masyarakat kurang siap siaga untuk menghadapi bencana tersebut. Pada artikel ini akan membahas tentang pengukuran dan perekaman suatu data karakteristik gempabumi berdasarkan fluktuasi medan magnet menggunakan sensor MEMS, kemudian data yang tersimpan pada perekam data dianalisa berdasarkan waktu setiap kejadian pengamatan (time stamp) untuk mengukur selang waktu (delay time) antara kejadian anomali medan magnet terhadap puncak getaran dengan magnitude terbesar. Uji coba perekam data dilakukan langsung di lapangan, yaitu memanfaatkan area yang memiliki aktifitas vulkanik. Kesimpulan dari penelitian untuk mendapatkan data getaran yang valid sesuai dengan teori Nyquist-Shannon maka pencuplikan data getaran dilakukan dengan frekuensi cuplik 2*Frekuensi maksimal masukan, yaitu minimal 40Hz dengan transformasi FFT pada sensor accelerometer menunjukkan frekwensi rendah gempa (≤ 20Hz) memiliki magnitude yang beragam dengan magnitude dominan pada frekwensi 5hz-10hz sedangkan pada sensor magnetometer menunjukkan frekwensi rendah gempa (≤ 66Hz) memiliki magnitude yang beragam dengan magnitude dominan pada frekwensi 5hz-10hz, 25hz-40hz, dan 50hz-60hz.

Abstract

Krajan is located about 20 km from the summit of Mount Merapi. The main problem in this village is the Community-based Drinking Water and Sanitation Program (PAMSIMAS) which has played a role in meeting the community's clean water needs, but has not been able to be used economically by the residents despite having abundant mountain springs. In addition, water problems arise especially during the rainy season, where water does not meet quality standards so it is not suitable for consumption. To optimize the use of springs that have an impact on green economy activities as well as improve people's welfare, the PKM Team of the IST AKPRIND Yogyakarta applies a (PLTMH) in Padukuhan Salam-Krajan, Wukirsari, Cangkringan. PLTMH was developed by utilizing abundant springs. By utilizing the water discharge from the water input (inlet) flow to the PAMSIMAS reservoir, the electricity generated can be used for street lighting as well as building ready-to-drink water installations using the electricity network from PLTMH. Based on the evaluation of the activity, the implementation of community service activities that harmonize the needs of partners with the competence of the Team is a very good model for implementing community service activities, so this kind of model needs to be continued. This PKM activity is able to provide opportunities to support the implementation of development that is oriented towards environmental and ecosystem aspects, able to improve the welfare of rural communities, plan sustainable development, a green economy, overcome poverty and produce ready-to-drink water products.
