Abstract

Tanah yang sering mengalami masalah dalam pembangunan konstruksi geologi rekayasa adalah tanah lempung. Kerusakan jalan yang selama ini sering dijumpai dikarenakan tidak tersedianya data California Bearing Ratio (CBR) serta konsistensi tanah. Tujuan dari penelitian ini adalah, mengetahui nilai CBR dengan alat DCP, meninjai evaluasi kekuatan lapis tanah dasar, menentukan batas konsistensi tanah, dan menginterpretasikan korelasi berdasarkan data CBR dan Plasticity Index (PI). Metode penelitian dilakukan dengan CBR dengan alat DCP, pengambilan sampel tanah, serta pengukuran indeks plastisitas tanah langsung. Pada daerah penelitian ini diketahui memiliki tingkat konsistensi plastisitas tanah yang tinggi, kohesi, dan tanah lempung dengan nilai PL sebesar 28,85% - 48%. Kemudian didapat nilai indeks plastisitas (PI) daerah penelitian yang memiliki nilai 25,15%-36,82%. Maka hasil PI ini mempunyai tingkat indeks plastis yang tinggi, tanah yang kohesif serta tipe tanah atau jenis yang lempung sehingga buruk untuk konstruksi di atasnya karena potensi swelling lempung. Kemudian untuk data CBR daerah penelitian didapat sebesar 5,05-5,55% dengan soil type lempung termasuk zona yang buruk/rendah.  The soil that often experiences problems in the construction of engineering geological construction is clay soil. Road damage that has often been encountered is due to the unavailability of California Bearing Ratio (CBR) data and soil consistency. The purpose of this research is to determine the CBR value using the DCP tool, review the evaluation of the strength of the subgrade layer, determine the soil consistency limit, and interpret correlation based on CBR and Plasticity Index data. The research method was carried out using CBR with a DCP tool, taking soil samples, and directly measuring the soil plasticity index. This research area is known to have a high level of consistent soil plasticity, cohesion, and clay soil with a PL value of 28,85% - 48%. Then the plasticity index (PI) value for the research area was obtained which had a value of 25,15% -36.82%. Therefor this plasticity index has high plasticity, cohesive properties and a clay type of soil so it is bad for construction on it because of the potential for clay swelling. Then the CBR data for the research area was found to be 5.05-5.55% with a clay soil type including poor/low zones.

Abstract

Penelitian ini dilakukan di Daerah Kecamatan Nglipar, Kabupaten Gunung Kidul, Provinsi Daerah Istimewa Yogyakarta. Daerah ini memiliki morfologi perbukitan-perbukitan serta lereng yang cukup curam dan juga terdiri dari batupasir, batupasir tufaan, dan breksi vulkanik. Berdasarkan kondisi geologinya, daerah penelitian cukup rentan terhadap bencana tanah longsor. Tanah longsor juga dapat terjadi akibat lokasi gerakan tanah berada di lereng yang curam dengan kondisi struktur tanah dan lereng yang tidak stabil. Penelitian ini bertujuan untuk menentukan zona kerawanan gerakan tanah pada daerah penelitian dengan menggunakan metode pembobotan dan penilaian dari setiap faktor dan dituangkan ke dalam bentuk peta spasial yang kemudian di tumpang tindih (overlay). Salah satu faktor utama yang mempengaruhi adalah kemiringan lereng dari landai hingga curam, serta jenis litologinya. Hasilnya adalah peta zonasi kerawanan longsor berdasarkan pada parameter penyebab longsor. Hasil akhir menunjukkan 3 zonasi, yaitu zonasi rendah mencakup 15% daerah penelitian, zonasi sedang 65%, dan zonasi tinggi 20%. This research was conducted in Nglipar District, Gunung Kidul Regency, Yogyakarta Special Region Province. This area has a morphology of hills and quite steep slopes and also consists of sandstone, tuff sandstone and volcanic breccia. Based on its geological conditions, the research area is quite vulnerable to landslides. Landslides can also occur due to the location of the ground movement being on a steep slope with unstable soil and slope structure conditions. This research aims to determine the zone of vulnerability to land movement in the research area using a weighting and assessment method for each factor and pouring it into a spatial map which is then overlaid. One of the main influencing factors is the slope of the slope from gentle to steep, as well as the type of lithology. The result is a landslide susceptibility zoning map based on landslide-causing parameters. The final results show 3 zoning, namely low zoning covering 15% of the research area, medium zoning 65%, and high zoning 20%.

Abstract

Menurut laporan BPBD, terjadi longsor di daerah Babakan Madang. Saat mempelajari aspek kebencanaan yang terkait dengan gerakan tanah, lereng adalah salah satu komponen yang paling penting yang dibahas. Dengan mempertimbangkan tipe batuan, karakteristik lereng, dan data DEMNAS, tujuan penelitian ini adalah untuk menentukan kelas kelerengan dan arah lereng. Kelerengan dan arah lereng membutuhkan data DEMNAS, sedangkan tipe batuan membutuhkan pemetaan geologi yang akurat. Selanjutnya, data yang dikumpulkan dibagi menjadi beberapa kelas berdasarkan parameter yang telah ditetapkan. Analisis yang dilakukan menunjukkan bahwa zonasi kelas kelerengan berkisar dari sangat rendah hingga sangat tinggi. Penelitian ini memiliki lereng yang berbeda dari utara ke selatan, menunjukkan variasi yang signifikan di seluruh area. Selain itu, jenis batuan yang ditemukan juga diklasifikasikan berdasarkan kualitasnya, berkisar dari sangat baik hingga sangat buruk. Dalam konteks mitigasi bencana tanah longsor, penelitian ini memberikan wawasan yang lebih mendalam tentang hubungan antara kelerengan, arah lereng, dan tipe batuan. Penelitian ini diharapkan dapat membantu perencanaan dan pembangunan infrastruktur yang lebih tahan terhadap longsor. According to the BPBD report, a landslide occurred in the Babakan Madang area. When studying disaster aspects related to ground movement, slope is one of the most important components discussed. By considering rock type, slope characteristics, and DEMNAS data, the aim of this research is to determine the slope class and slope direction. Slope and slope direction require DEMNAS data, while rock types require accurate geological mapping. Next, the collected data is divided into several classes based on predetermined parameters. The analysis carried out shows that the slope class zoning ranges from very low to very high. This study has different slopes from north to south, showing significant variation across the area. Apart from that, the types of rocks found are also classified based on their quality, ranging from very good to very poor. In the context of landslide disaster mitigation, this research provides deeper insight into the relationship between slope, slope direction, and rock type. It is hoped that this research can help plan and build infrastructure that is more resistant to landslides.

Abstract

Fasies dapat diartikan dengan suatu tubuh batuan yang didalamnya terdapat berbagai ciri khas dan suatu karakter tertentu yang berkaitan dengan faktor kimia, fisika dan biologi, dapat dilihat dari litologi batuan ataupun struktur sedimen yang bekerja. Fasies dapat digunakan untuk mengetahui lingkungan pengendapan secara keseluruhan, yang kemudian diharapkan bisa menjadi acuan untuk melakukan kegiatan salah satunya seperti eksplorasi minyak dan gas. Tujuan dari penelitian ini adalah untuk mengetahui fasies yang terdapat di Formasi Kais Cekungan Salawati yang berlokasi di kepala burung dari pulau Irian Jaya. Analisis fasies ini menggunakan data log yang berasal dari salah satu sumur pada daerah penelitian. Fasies batuan karbonat pada Formasi Kais Cekungan Salawati adalah fasies mudstone to wackestone, fasies wackestone to packstone dan fasies wackestone (Dunham, 1962). Facies can be interpreted as a body of rock in which there are various distinctive features and a certain character related to chemical, physical and biological factors, which can be seen from the rock lithology or sedimentary structure at work. Facies can be used to determine the overall depositional environment, which is then hoped to be a reference for carrying out activities such as oil and gas exploration. The aim of this research is to determine the facies found in the Kais formation of the Salawati Basin located on the bird's head of Irian Jaya Island. This facies analysis uses log data originating from one of the wells in the study area. The carbonate rock facies in the Kais formation of the Salawati Basin is the mudstone to wackestone facies, wackestone to packstone facies and wackestone facies (Dunham, 1962).
