Abstract

Telah dilakukan penelitian dengan tujuan untuk mengetahui unsur penyusun dan jumlah unsur yang terkandung dalam tanah Desa Babange Kabupaten Bantaeng dengan menggunakan metode XRF (X-ray fluorescense). Desa Babange Kabupaten Bantaeng terletak di daerah kaki gunung api Lompobattang yang artinya bisa didapatkan potensi geothermal pada lokasi penelitian. Pengambilan sampel tanah dilakukan pada tiga titik berbeda dengan kedalaman masing-masing 0 cm, 60 cm dan 100 cm. Hasil uji XRF menunjukkan unsur yang terkandung dalam tanah Desa Babange adalah besi (Fe), titanium (Ti), silikon (Si), calcium (Ca), mangan (Mn), zirkonium (Zr), kalium (K), stronsium (Sr), seng (Zn), niobium (Nb), bromin (Br), iodin (I), indium (In), tembaga (Cu), timah (Sn), barium (Ba), galium (Ga) dan nikel (Ni). Unsur dengan kadar tertinggi adalah Fe, Ti, Si, Ca dan Mn. Unsur Fe dengan kadar tertinggi didapatkan pada titik C pada kedalaman 100 cm sebesar 71,72%. Unsur Ti dengan kadar terbesar didapatkan pada titik A pada kedalaman 50 cm sebesar 6,77%. Unsur Si dengan kadar terbesar didapatkan pada titik A pada kedalaman 100 cm sebesar 13,01%. Unsur Ca dengan kadar terbesar didapatkan pada titik A pada kedalaman 0 cm sebesar 2,87%, dan unsur Mn dengan kadar terbesar terdapat pada titik C pada kedalaman 0 cm sebesar 3,10%. Berdasarkan besarnya kandungan unsur yang telah diperoleh maka pada lokasi penelitian memiliki potensi geothermal yang rendah meskipun terdapat pada daerah kaki gunung api.

Abstract

Abstrak. Bencana alam tanah longsor umumnya terjadi di wilayah yang memiliki sisi (bidang) kemiringan seperti bukit, pegunungan, dan wilayah lereng. Kabupaten Barru merupakan salah satu daerah yang rawan akan risiko longsor karena kondisi topografi yang berbukit-bukit dan berada di daerah pegunungan dengan kondisi tanah yang cukup rentan terhadap terjadinya tanah longsor. Penelitian ini bertujuan memetakan risiko longsor menggunakan metode pembobotan parameter dan Inarisk BNPB dan menganalisis daerah yang memiliki tingkat risiko longsor serta membandingkan kedua metode tersebut. Parameter yang digunakan dalam metode pertama adalah pembobotan parameter yaitu kemiringan lereng, penggunaan lahan, jenis tanah dan geologi berdasarkan data informasi BAPPEDA Kabupaten Barru tahun 2021 dan data curah hujan dari BMKG wilayah Maros Sulawesi Selatan (2017-2021). Metode kedua adalah inarisk BNPB menggunakan data spasial melalui website Inarisk BNPB. Hasil penelitian menunjukkan bahwa wilayah di Kabupaten Barru dikategorikan sebagai daerah dengan kondisi tanah longsor agak rawan pada daerah perbukitan dan pegunungan, sedangkan pada bagian dataran rendah sedikit rawan. Sebaran risiko longsor daerah berdasarkan metode pembobotan parameter diklasifikasikan tiga kelas, yaitu tinggi: 2.335,64 ha tersebar di Kecamatan Pujananting, Tanete Riaja, dan Mallusetasi; sedang: 114.696,43 ha tersebar di seluruh Kabupaten Barru; dan rendah: 726,56 ha tersebar di Soppeng Riaja dan Balusu. Metode ini lebih akurat dalam merepresentasikan kondisi daerah rawan longsor dibandingkan metode Inarisk BNPB. Berdasarkan hasil penelitian, maka pemerintah setempat dapat melakukan strategi kebijakan dalam menangani daerah yang teridentifikasi rawan longsor dan pihak masyarakat lebih peduli terhadap upaya penanggulangan rawan bencana.Kata Kunci: bencana rawan longsor; inarisk BNPB; pembobotan parameter; pemetaan risiko bencana  Abstract. Landslides natural disasters generally occur in areas that have slopes, in the form of mountains, hills and slope areas. Barru Regency is one of the areas that are prone to landslide risk due to hilly topography and is located in a mountainous area with soil conditions that are quite susceptible to landslides. This study aims to map the risk of landslides using the parameter weighting method and the BNPB Inarisk and analyze areas that have a level of landslide risk and compare the two methods. The parameters used in the first method are parameter weighting, namely slope, land use, soil type and geology based on information data from BAPPEDA Barru Regency in 2021 and rainfall data from the BMKG in the Maros region of South Sulawesi (2017-2021). The second method is the BNPB Inarisk, uses spatial data through the BNPB Inarisk website. The results showed that the area in Barru Regency was categorized as an area with slightly prone to landslides in hilly and mountainous areas, while in the lowlands it is a little prone. The distribution of regional landslide risk based on the parameter weighting method is classified into three classes, namely high: 2,335.64 ha spread out in Pujananting, Tanete Riaja, and Mallusetasi Districts; medium: 114,696.43 ha spread throughout Barru Regency; and low: 726.56 ha spread over Soppeng Riaja and Balusu. This method is more accurate in representing the condition of landslide-prone areas than the Inarisk BNPB method. Based on the results of the study, the local government can carry out policy strategies in dealing with areas identified as prone to landslides and the community is more concerned with disaster-prone management efforts. Keywords:  landslide prone disaster, inarisk BNPB, parameter weighting, disaster risk mapping

Abstract

Springs are a problem in areas where geographic conditions are predominantly hot with low annual rainfall. Water is one of the basic needs for all living things on Earth, both plants, animals and especially humans. If there is a scarcity of spring sources, it is certain that daily activities are very disturbed. Scarcity of springs as happened in Jenetallasa Village greatly influences community activities in the Village. Prolonged drought results in increasingly severe water scarcity that occurs. Based on this problem, a field study was conducted to estimate the aquifer zone. Aquifers are a source of springs located in cavities brought under the surface of the ground which reminisce or flow. Aquifers themselves can be predicted without existence of drilling or excavation. Detection of aquifers can be done using geoelectric methods with different configurations. Our field study this time uses a schlumberger configuration with a length of 120 meters with an approximate depth of 60 meters below ground level.

Abstract

The research of the Saddang fault pattern based on the level of seismicity and focal mechanism (a case study in January 2010- July 2020) aims to determine the level of seismicity in the Saddang fault area and the Saddang fault focal mechanism in the 2010-2020 earthquake. The data which were used were secondary data from the BMKG catalog from January 2010 - July 2020. The coordinating limit is 118.50 ° East Longitude 120.60 ° East Longitude and (-2.60 ° South Latitude) - (-5.70 ° South Latitude) there were 1425 earthquakes. This research used ArcGis application to measure seismicity distribution map and seiscomp3 to measure focal mechanism. Furthermore, the focal mechanism divides the region into three regions. The results which obtained from the seismicity map obtained a high level of seismicity with a shallow depth. Which was caused by the lack of factors from the active Saddang fault and Sulawesi who had four plate junctions. The results of the focal mechanism in each region had the whole type of shear fault or horizontal. Keywords: Earthquake, geology software ArcGis, software seisco
