"ABSTRACT
Di bidang panas bumi, data magnetotelluric biasanya digunakan untuk mendapatkan informasi resistivitas di bawah permukaan. Salah satu pengolahan data magnetotelurik adalah inversi data, dimana inversi adalah proses mengubah data magnetotelurik menjadi penampang resistivitas. Inversi yang digunakan dalam penelitian ini adalah inversi 1D dan 2D. Salah satu informasi bawah permukaan yang menjadi fokus eksplorasi panas bumi adalah lapisan tudung yang dicirikan oleh nilai resistivitas kecil. Salah satu mineral yang terkandung dalam batu yang diubah adalah smektit. Smektit terbentuk pada suhu 20-180oC, pada suhu di atas 70oC, smektit menjadi tidak stabil dan lapisan smektit-ilit menjadi tidak terdeteksi pada batuan berpori pada suhu di atas 200oC. Untuk mendeteksi smektit ini, teknik sederhana, yaitu titrasi metilen-biru (MeB), digunakan pada batuan pemboran. Teknik ini telah lama digunakan untuk memperkirakan kandungan smektit pada batuan yang dipotong dengan baik di bidang panas bumi. Data penelitian diambil di wilayah kontrak Sarulla, bidang Namora I-Langit yang merupakan bidang panas bumi yang berlokasi di Sumatera Utara. Korelasi antara nilai MeB dengan data resistivitas berbanding terbalik. Ini karena nilai MeB yang tinggi dari konten smektit dalam lapisan juga tinggi, oleh karena itu nilai CEC dalam lapisan juga akan tinggi, akibatnya nilai resistivitas lapisan akan rendah.

ABSTRACT
Kata kunci: Magnetotellurik, Inversi 1D & 2D, MethyIn the geothermal field, magnetotelluric data are commonly used to obtain resistivity information below the surface. One of magnetotelluric data processing is data inversion, wherein inversion is a process of changing magnetotelluric data into resistivity cross section. The inversion used in this research is 1D and 2D inversion. One of the subsurface information that is the focus of geothermal exploration is the hood layer which is characterized by a small resistivity value. One of the minerals contained in the altered rock is smectite. Smectites are formed at temperatures of 20-180oC, at temperatures above 70oC, smectites become unstable and smectite-illite layers become undetectable in porous rocks at temperatures above 200oC. To detect this smectite, a simple technique, namely methylene-blue (MeB) titration, is used on the drilling rock. This technique has long been used to estimate smectite content in well-cut rocks in the geothermal field. The research data was taken in the Sarulla contract area, Namora I-Langit field which is a geothermal field located in North Sumatra. The correlation between MeB values ​​with resistivity data is inversely proportional. This is because the high MeB value of the smectite content in the layer is also high, therefore the CEC value in the layer will also be high, as a result the resistivity value of the layer will be low.

""There was a time when they lived in the village of Beit Daras, and the sun was hot and the earth was rich. There were ruins dating back to the Crusades; now their homes, too, are ruins, and they are refugees in the small strip of Gaza. And yet, when young Khaled dies, and moves on to the afterlife, it is back in Beit Daras that he finds himself. And from here he may slip through history, watching the continuing the story of his matriarchal family. He sees his grandmother, Nazmiyeh, once the prettiest, baddest girl in the town, the eternal ringleader. The other girls felt she hung the sky. He sees his mother, Alwan, who loves quietly and strongly, and who sustains the family through her embroidery work, stitching the stars and moon in place. He sees the great-aunts and cousins, and his sunny little sister, Rhet Shel. Finally, there is the branch of the family that moves to Kuwait, and then to America, where Nur, his mother's cousin, begins to lose herself. She will return to Mediterranean shores to find her past, and rediscover the ties of kinship that transcend distance and even death. Born of the violent, troubling history which continues to rage forth and claim its dead, The Blue Between Sky and Water is very much a novel of survival, and of the vivid, powerful women whose world they manage, with each day, to enlarge and to enliven"--Publisher."
