Abstract

Sensor seismik merupakan komponen utama dalam bidang seismologi. Salah satu sensor seismik yang sering digunakan geofon, namun geofon memiliki kekurangan dalam mendeteksi getaran frekuensi rendah di bawah 10Hz. Dengan adanya kekurangan tersebut menjadi salah satu peluang bagi sensor MEMS yang memiliki rentang frekuensi lebih lebar dibandingkan dengan geofon.Pada penelitian ini sensor MEMS terkonfigurasi dengan pengkondisi sinyal yang telah dilengkapi dengan rangkaian integrator. Fungsi dari rangkaian integrator ini untuk mengubah MEMS Percepatan menjadi MEMS Kecepatan. Sehingga MEMS mampu mendeteksi kecepatan gerakan tanah menyerupai geofon. Hasil respon sinyal MEMS menunjukkan bahwa MEMS Kecepatan mampu mendeteksi getaran frekuensi 0.01Hz hingga 100Hz. Berdasarkan hasil respon frekuensi menunjukkan bahwa MEMS mampu digunakan sebagai sensor seismik.

Abstract

Volcanic eruption is one of the phenomena that can change the volcanic landscape drastically. Monitoring of volcanic edifices after eruptions should be considered to further understand the potential hazards in the future. Satellite monitoring is a reliable technique for assessing deformation in a volcano. InSAR was applied to detect material build-up after the eruption phase of Semeru Volcano in December 2022. As a consequence of the opening crater along with the InSAR result, a lahar product after the eruption was deposited in the southwest direction. Significant deformations were indicated by PS-InSAR near the crater, which was characterized by a LOS displacement of -10 to -40 mm/year, indicating scouring of the pyroclastic material moving down the slope.  The accumulation of pyroclastic flows from the abrading process below was detected in the proximal zone of Semeru, as shown by the positive LOS displacement ranging from 10 to 40 mm/year. The field survey conforms to the PS InSAR results, where unconsolidated material, ranging in size from gravel to boulders, piles up approximately 4-5 m in Curah Kobokan.  Highly unconsolidated material tends to move easily by water and threaten the surrounding settlements. Overlying PS InSAR and drainage pattern in the flank of Semeru, concluding several locations that have a high-risk potential of being affected by lahar flows are Curah Kobokan, Supiturang Village, Pronojiwo District, then Tulungrejo, Pasropan Village, Pasrujambe District, Lumajang Regency.

Abstract

Water is an inexhaustible resource on earth and a renewable source of energy. The raw water consumed by the people of Sampang is very limited. Based on the contour of the land, raw water can be processed into drinking water or clean water through piping and a gravity system. However, people's homes are far away, so the construction of these facilities is expensive. This research is beneficial for the government or the local community. This study uses geophysical methods that can see the earth's surface, one of which is the Schlumberger configuration resistivity geoelectric method with 7 measurement points. The lithology of the rocks in the study area includes: topsoil, claystone, claystone, sandy claystone, conglomerate rock, limestone, sandy limestone, marl, sandstone, clay sandstone. After doing detailed calculations, the results of the recapitulation of the total costs at the research location are around Rp. 250,600,00.00. Up to Rp. 287,147,000.00

Abstract

The eruption of Mount Semeru on December 4, 2021, caused a fairly high death toll of up to 50 people. The high number of fatalities is caused by the lack of mitigation capacity and the absence of community involvement in mitigation efforts. Increased mitigation capacity can be done by presenting disaster education to the communities. Thus, we applied the concepts of school watching and town watching in Pronojiwo District, Lumajang Regency. School watching was implemented in eight schools located at Sidomulyo Village. We also carried out town watching in Sidomulyo Village and brought out ±33 residents to the Sidomulyo village hall. The implementation of school watching and town watching in Pronojiwo District can increase community involvement in disaster mitigation efforts and public awareness of mitigation efforts.

Abstract

Tremor di Gunung Sinabung pertama kali terekam pada Oktober-November 2013. Tremor dapat mengindikasikan aktivitas vulkanik pada gunung api tersebut, seperti osilasi aliran fluida, pergerakan fluida, sistem hidrotermal, dan resonansi aktivitas dapur magma, sehingga informasi karakteristik tremor yang muncul di Gunung Sinabung sangat dibutuhkan. Penelitian ini dilakukan untuk menentukan karakteristik tremor Gunung Sinabung pada periode Oktober-November 2013 berdasarkan analisis spektrum frekuensi, waveform cross-correlation dan polarisasi seismik. Berdasarkan metode tersebut diharapkan dapat memberikan informasi frekuensi dominan, kesamaan bentuk antardata tremor dan lokasi sumber sinyal tremor. Data tremor Gunung Sinabung periode Oktober-November 2013 telah terpilih 260 data. Analisis spektrum frekuensi menunjukkan bahwa tremor Gunung Sinabung memiliki nilai frekuensi dominan yakni 1-3 Hz. Berdasarkan bentuk spektrum frekuensinya, tremor Gunung Sinabung dibedakan menjadi dua jenis yaitu tremor harmonik dan non harmonik. Nilai koefisien korelasi 0,5-0,9 ditunjukkan dari hasil analisis waveform cross-correlation yang berarti terdapat kesamaan bentuk sinyal tremor. Berdasarkan variasi nilai koefisien korelasi dan waktu letusan Gunung Sinabung, maka terdapat tujuh zona waktu dengan letusan 8 November 2013 yang memiliki nilai koefisien korelasi tertinggi. Berdasarkan analisis polarisasi seismik diperkirakan sumber tremor berada di selatan kawah dengan arah 90°-120° dari Stasiun Mardinding. Tremor Gunung Sinabung diperkirakan bersumber di -0,5-2,4 km di atas permukaan air laut.

Abstract

Tiris area is one area that has geothermal prospects. Tiris area is located in the Tiris sub-district, Probolinggo regency, East Java. This study aims to identify the subsurface structure of the Tiris geothermal area using Topex gravity and DEM SRTM imagery data. The Topex gravity data obtained is still in Free Air Anomali (FAA) form, so it is necessary to make Bouguer and terrain corrections to get a complete Bouguer anomaly. A residual Bouguer anomaly is needed to study shallow subsurface structures. This anomaly is obtained by separating the residual and regional anomalies from the complete Bouguer anomaly using the moving average method. The study area has residual Bouguer anomaly values ranging from -0.5 to 2.9 mGal. The low residual Bouguer anomalies are seen in the body of the Lamongan volcano (LV) and the Tiris geothermal area (TGA). The study of subsurface structures is focused on the LV and the TGA through Forward 2D modeling. The A-A' cross-section illustrates the subsurface of LV, while the B-B' cross-section illustrates the subsurface of TGA. Cross-section A-A' modeling results show that the source of the low anomaly is in the second layer D2 = 1.24 g/  at a depth of 4.0 to 0.6 km below sea level and is suspected to be magma because it has a low density. Cross-section B-B' modeling obtained a low anomaly source at the second layer D2 = 2.03 g/  at a depth of 4.0 to 2.8 km below sea level and is suspected to be intrusive rock. The lineament display on the 2D of DEM SRTM map for the 45o and 135o azimuths shows that the TGA region has a high lineament density, and the orientation of the surface geological structure in the study area is dominant in a northwest-southeast direction.

Abstract

Entropi permutasi adalah metode statistika yang dapat menentukan tingkat kompleksitasi data time-series. Metode ini dapat digunakan pada data hasil perekaman seismometer di gunung api, termasuk Gunung Raung. Gunung Raung yang menunjukkan aktivitasnya pada Januari 2015 dapat dihitung nilai entropi permutasinya. Variasi entropi permutasi menunjukkan bahwa stasiun RAUN, MLLR, dan POSR memiliki tingkat kompleksitas yang rendah ketika terjadi aktivitas letusan. Variasi entropi permutasi di stasiun KBUR pada saat terjadi letusan tidak menunjukkan penurunan tingkat kompleksitas, karena adanya tremor yang mendominasi. Penurunan nilai entropi permutasi karena adanya aktivitas tremor dapat digunakan sebagai early warning system. Namun, hal ini butuh penelitian lebih lanjut.

Abstract

Geothermal energy is one of the natural resources found in Pacitan Regency, alongside mining and geotourism. Geothermal manifestations in Pacitan Regency take the form of hot springs located at two points: Tinatar in the Punung District and Karangrejo in the Arjosari District. This research primarily focuses on magnetic measurement methods at the Karangrejo hot spring manifestation to provide information about its subsurface geological conditions. Data acquisition was conducted using 2 Proton Precision Magnetometers (PPM) of the Geotron G-5 brand as both base and rover instruments. The acquired data was processed with diurnal correction, IGRF correction, separation of residual-regional anomalies, and Reduce to Pole (RTP) transformation. The research results show magnetic anomaly variations in the study area ranging from -220 nT to 200 nT. Some geological structures that could potentially be associated with the Karangrejo hot spring manifestation are north-south trending faults and northeast-southwest trending faults, while the lithology of the study area is dominated by kaolin alteration and andesite rocks. It is estimated that the Karangrejo geothermal system is a fault-hosted geothermal system resulting from fault activity.

Abstract

A share wave velocity model to a depth of 30 meter (vs30) can be used to find the type of the ground as a preventive action against earthquake disaster mitigation. Vs30 is obtained from the inversion of ellipticity curve using HVTFA method. HVTFA method is a method that can minimize the love curve in the ellipticity curve. Therefore, a more reliable share wave velocity can be obtained. It is necessary to find reliability of a model in a further research. The objectives of this research were to find the reliability of HVTFA and HVSR methods and determine the reliability of vs30 model from the result of inversion of Rayleigh-wave ellipticity curve using HVTFA method with duration of microtremor measurement of 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours and 6 hours. Data used in this research were microtremor data. The microtremor data were processed using HVTFA and HVSR method in Geopsy software to find the ellicpticity curve. Next, the inversion of ellipticity was carried out in dinver software to obtain the share wave velocity model. After that, the error value from the model was calculated using vs%Miss, Boun%Miss, Ev, and Eb. The error value of HVTFA method still met the requirement of reliable model, but not the error value of HVSR method. The high error value in HVSR method was found in Bound%Miss and Eb. It meant that the share wave velocity of HVSR method had a high error value in the estimation of surface depth and thickness. Therefore, HVTFA method produced a more reliable vs30 model than HVSR method. In addition, the velocity model of HVTFA method from microtremor data with duration of 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours and 6 hours also had reliable model.

Abstract

The research aims to analyze the feasibility of managing a green campus photovoltaic solar power plant at the National Institute of Technology Malang. The method used is a literature review study. This method involves searching, selecting, and analyzing articles, books, journals, and other literature sources relevant to this research topic. The research results show that the National Institute of Technology (ITN-Malang) photovoltaic solar power plant (Pembangkit Listrik Tenaga Surya /PLTS) has fulfilled the energy efficiency aspect, an indicator of a green campus. Apart from that, the research results reveal that the feasibility of managing the National Institute of Technology (ITN-Malang) photovoltaic solar power plant (PLTS) from a green campus perspective considers environmental, economic, and social aspects. These three aspects have met the standards for the feasibility of managing a solar photovoltaic power plant at a university that meets green building criteria, including energy conservation, energy efficiency, and renewable energy. However, further studies are still needed related to environmental aspects, especially the use of land in the solar photovoltaic power plant area and the handling, development, and management of solar panel waste. Keywords: green campus, feasibility, management, solar power plant
