Abstract

Mount Gupit is an area with gold mineralization potential which is part of the Menoreh Mountains, in the Magelang area. Mineralization potential mapping was carried out using geophysics, namely the Induced Polarization method. Induced Polarization Method measurements were carried out in 5 trajectories in a relatively west to east direction and with varying path lengths. The configuration used is a dipole-dipole configuration with a: 10 meters and n: 1-6. Interpretation is carried out on the results of the Resistivity and Chargeability data inversion. The inversion results show a resistivity range from 2 to 400 Ohm-m. Resistivity values are divided into three criteria, namely low with a value of less than 10 Ohm-m as clay rock, medium with a range of (10-75) Ohm-m as pyroclastic breccia and high with a value greater than 75 Ohm-m as intrusion or chunks of andesite. The inversion results show that the chargeability value varies from 2 to 80 ms. This value is divided into three criteria, namely low (<10 ms), medium (10 to 35) ms and high (>35 ms). Low chargeability values are interpreted as zones that are not mineralized so that there are no metal minerals. The mineralized zone is being interpreted from a moderate chargeability value. Meanwhile, a high chargeability value is interpreted as a zone that is strongly mineralized and contains significant metallic minerals. The existence of a mineralized zone stretches from track 2 to track 5 to the north, while the zone has disappeared or been exhausted in track 1 to the south of the research area.

Abstract

Sekolah Dasar Negeri 09 Pasaman merupakan sekolah dasar yang dibangun pada tahun 1973 dan memiliki 3 gedung utama yaitu gedung A, B dan C. Khusus gedung B sendiri dibangun pada tahun 2019, dimana gedung tersebut mengalami banyak kerusakan non-struktural pasca gempa bumi di Kabupaten Pasaman Barat. Gempa bumi ini terjadi pada tanggal 25 Februari 2022 yang berkekuatan 6,2 SR dengan kedalaman 10 km dan tidak berpotensi tsunami. Penelitian ini bertujuan untuk menghitung deformasi horizontal pada struktur beton bertulang arah x dan y pada Gedung Sekolah dengan menngunakan dinding bata ringan. Deformasi horizontal mengacu pada perpindahan atau pergeseran relatif dalam struktur akibat beban yang diterima. Deformasi struktur bertujuan untuk mengetahui respons struktur terhadap beban yang bekerja pada Gedung Sekolah, sehingga gedung dapat tetap berfungsi dan aman saat terjadi gempa atau situasi darurat lainnya. Hasil penelitian menunjukkan bahwa nilai displacement arah x dan y menghasilkan respons perpindahan yang berbeda pada kedua arah tersebut. Nilai displacement tertinggi tercatat sebesar 2,646 mm pada arah x dan 10,05 mm pada arah y. Berdasarkan perhitungan simpangan antar tingkat, semua lantai dalam Gedung Sekolah memenuhi batas kriteria penerimaan yang diizinkan. Nilai simpangan antar lantai terbesar sebesar 52,27 mm tidak melebihi nilai ambang batas yang disyaratkan. Gedung Sekolah telah dirancang dengan mempertimbangkan pengendalian simpangan antar lantai sesuai dengan persyaratan standar yang berlaku. Pengendalian simpangan antar lantai yang baik berkontribusi pada kenyamanan dan keselamatan siswa.

Abstract

Critical thinking skills in teenagers can be trained in learning Indonesian with anecdotal text material. In an anecdote text, there is an implied meaning that the author wants to convey. To be able to find out the implied meaning, an implicature analysis is needed. A statement that contains implicatures can be found anywhere, such as in the YouTube content Podkaesang Depan Pintu (PDP). The Podkaesang Depan Pintu (PDP) content attracts the public's attention because it contains a lot of discussion about politics, but also contains elements of comedy. Therefore, this research aims to (1) describe the types of implicatures in Podkaesang Depan Pintu (PDP) Youtube content (2) describe the function of implicatures used in Podkaesang Tepi Pintu (PDP) Youtube content (3) describe the preparation of research results for teaching materials (E-Module) anecdotal text material for class This research uses a qualitative approach with an analytical description method. The technique used in research is listening and taking notes. The results of the research show that in six episodes of Podkaesang Depan Pintu (PDP) content, 18 implicatures were found, consisting of 10 conventional implicatures and 8 conversational implicatures. The implicature functions found were 18 data consisting of the assertive functions 'state', 'express opinions' and 'complain'. As for the expressive function, there are 'to criticize', 'criticize', 'criticize' and 'praise'. The dominant function that appears is the assertive function of 'declaring'. Apart from that, the results of this research were also used to prepare teaching materials in the form of E-Modules for anecdotal text material for class
