Abstract

Aktivitas sesar merupakan faktor utama terjadinya gempa bumi seperti yang terjadi di Pulau Lombok. Sesar diduga banyak terdapat di Wilayah Lombok, baik sesar skala mayor maupun sesar minor. Oleh karena itu perlu dilakukan pemetaan keberadaan sesar dan analisis geometrinya, sehingga resiko bahaya dapat dimitigasi sebelum gempa khususnya di Kayangan Lombok Utara. Tujuan penelitian ini adalah untuk mengetahui keberadaan sesar dan menganalisis geometrinya di Desa Selengen Kayangan Lombok Utara. Metode yang digunakan adalah metode Geolistrik 2D. Hasil penelitian menunjukkan bahwa sesar yang terdapat di Desa Selengan adalah sesar mikro membentuk garis melalui rekahan yang tersingkap memanjang ke arah Timur Laut. Geometri rata-rata sesar: lebar 15,8 m, kedalaman 16,8 m dan Strike  Dip  Timur Laut (N37E/77). Penelitian selanjutnya akan dikaji tingkat kerawanan dan potensi likuifaksi dengan wilayah yang lebih luas menggunakan metode lain.

Abstract

Philosophy and science are human efforts to understand the concepts and methods of a scientific discipline. Changing times and developments have ushered in a philosophy of configuration by showing how the "tree of knowledge" thrives and branches out from the respective disciplines. This study aims to examine philosophy and science and their relevance in the Industrial Revolution 4.0 era. This research method uses the hermeneutic method in explaining the reality that occurs with elements of interpretation and description. The results of the research can be described that the study of the relationship between philosophy and science has developed so rapidly. Philosophy and science are indispensable in the development of science and technology which is marked by sharpening of scientific specialization, because by studying philosophy scientists are expected to be aware of its limitations so as not to get caught up in intellectual arrogance. It is impossible to fight against the discourse on the development of science and technology, but rather to reduce the negative impact of technology itself. In the era of the Industrial Revolution 4.0 and Society 5.0, community groups are heterogeneous, so that very complex problems arise related to technological developments and can change the mindset of human life to patterns of life that are more sophisticated with the power of technology. like robots and the internet. Thus, science which is used as an axiological milestone in directing and controlling the development of science and technology in a positive way for the benefit of humanity and its environment is philosophy and science.

Abstract

Radial Derivative Forward Modeling of Gravity Anomalies for Identification of Cylindrical Geological Features. The gravity method is a geophysical method with exploration costs that are quite cheap compared to other geophysical methods. This method is based on the density contrast of the target body with the surrounding. The cylindrical body is one of the targets among various other geological features. This research was conducted to test the ability of radial derivatives of gravity anomalies for targets in the form of cylindrical body. Radial derivatives consist of a first derivative and a second derivative. Forward modeling of cylindrical geological features is carried out analytically and with finite elements. Both calculations were carried out with a computer program based on Matlab. The results show that there is no difference in results either analytically or finite element wise. This method has been proven to be able to provide clear boundary positions on cylindrical geological features.
