Abstract

Batupasir adalah batuan sedimen klastik yang banyak digunakan oleh orang-orang di berbagai industri. Batupasir Formasi Pulau Balang di wilayah Loa Tebu Kalimantan Timur, Indonesia, menjadi subjek penelitian ini. Meski Loa Tebu termasuk wilayah kecil, namun banyak hal yang sangat menarik untuk dipelajari di sana. Pengaruh sifat fisik dan mineralogi batupasir terhadap uji kuat tekan uniaksial pada Formasi Pulau Balang pada daerah Loa Tebu belum pernah diteliti sebelumnya. Untuk mendapatkan tegangan-regangan, Modulus Young, dan nisbah Poisson menggunakan uji kuat tekan uniaksial (UCS), digunakan pengamatan makroskopis (berupa deskripsi petrologi untuk sifat fisik batupasir) dan mikroskopis (berupa analisis petrografi untuk mineralogi batupasir). Batupasir di daerah penelitian memiliki sifat fisik yang beragam, antara lain batupasir sangat halus sampai sedang dengan semen karbonat dan non karbonat. Sifat fisik batupasir yang meliputi ukuran butir, struktur sedimen, jenis semen, tingkat pelapukan, dan komposisi fragmen berpengaruh terhadap kuat tekan. Menurut temuan analisis laboratorium dan pengujian mineral kuarsa dan litik yang dominan dalam mineralogi batupasir, geometri ukuran mineral membuat Lithic Wacke (Pettijohn, 1975) menjadi batuan yang lebih kuat. Menurut klasifikasi Tamrock (1988), kekuatan mulai dari 4.092 MPa hingga 125.655 MPa, kekuatan batuan dari kedua belas sampel dikategorikan sebagai "sangat lunak" hingga "keras" berdasarkan domainnya.

Abstract

The dependence on the use of non-renewable fossil energy in society certainly causes various problems, one of which is environmental problems in the form of increased carbon emissions. Fossil energy will also be increasingly limited in the future due to increased energy use, so a transition to new renewable energy is needed. Indonesia has considerable potential in New Renewable Energy, but the utilization and understanding of New Renewable Energy among the public remain low. The renewable energy was only 13,09% in 2023. This is due to Indonesia’s continued focus on fossil energy. Through this Service Program, it aims to socialize the potential and utilization of New Renewable Energy in Indonesia, especially in the samarinda area. The stages of this program include discussion and socialization of the potential amount of New Renewable Energy in Samarinda that can be utilized for energy needs among the community. This program provides understanding and awareness to the public about the importance of transitioning to New Renewable Energy and creating a commitment between the city government and the community regarding the transition to New Renewable Energy. This activity is expected to be the beginning of a change in the use of energy sources to create more environmentally friendly environmental conditions.
