Abstract

Penelitian geofisika dengan  menggunakan metode magnetik yaitu dengan alat Magnetometer Fluxgate. Luas daerah penyelidikan ± 1 km x 1 km, dibatasi oleh koordinat geografis antara  127° 27’ 42” s/d 127° 27’ 43” BT dan 0° 43’ 17” s/d 0° 43’ 19” LU . Penelitian ini bertujuan untuk mengetahui posisi sumber prospek panas bumi di daerah Akesahu, Pulau Tidore berdasarkan data anomali medan magnet. Data medan magnet total yang terukur adalah medan utama, medan luar dan medan anomali. Untuk menghilangkan efek-efek anomali dari medan magnet luar dan anomali medan magnet utama dilakukan perhitungan koreksi variasi harian, koreksi drift (kesalahan alat), koreksi penyesuaian, koreksi IGRF, dan pemisahan anomali residual dan  regional. Hasil penelitian  menunjukkan bahwa, daerah Akesahu, Pulau Tidore memiliki potensi panas bumi yang masih cukup besar yang ditandai dengan adanya manifestasi panas bumi berupa mata air panas. Anomali  medan magnet daerah Akesahu ditunjukkan dengan adanya anomali yang rendah (0.90 sampai dengan -2163.09 nT)  yang  memanjang arah utara-selatan di bagian Timur Pulau Tidore. Disamping itu di sekitar mata air panas Akesahu  secara geologis didukung dengan adanya empat buah sesar normal. Ini sebagai sistem pengontrol panas bumi yang lainnya di Pulau Tidore.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui potensi panas bumi dan sebaran air panas di sekitar Kelurahan Tobololo dan Kelurahan Sulamadaha, Pulau Ternate bagian utara. Hasil pengukuran magnetik di lapangan haruslah dihitung terlebih dahulu agar bisa  mendapatkan anomali magnetik yaitu medan magnet total dikurangi dengan magnet variasi harian, serta dikurangi dengan medan magnet utama bumi(nilai IGRF). Nilai IGRF 40137.7, Nilai medan magnet total yang terbaca pada fluxgate magnetometer sangat bervariasi antara 44907.9 nT s/d 73351.8 nT ,Total koreksi  yang didapat setelah medan magnet total dikurangi magnet variasi harian dan dikurangi nilai IGRF. Nilai anomali magnetik yang didapat setelah nilai magnet total dikurangi dengan nilai total koreksi yaitu berkisar antara 4791.7 nT s/d 33235.9 nT. Sebaran suhu airtanah dengan lokasi pengukuran memanjang lebih dari 5 km dan lebar 1 km dari bibir pantai hingga ke arah ketinggian dimana sumur gali atau sumur bor masih ditemukan. Suhu airtanah berkisar 26oC – 35.5 oC. Suhu air tertinggi hanya terdapat di dua titk mata air, yakni di Desa Tobololo dan Desa Sulamadaha. Ini menunjukkan perbedaan suhu hampir pada semua air sumur.Kata Kunci: air panas, gunung api, magnetik.

Abstract

School yard is the most appropriate learning media to support learning creativity for learners. The narrow use of school yard has not been well implemented so that the students' ignorance towards the environment is closely related to the decreasing environmental quality in schools. To improve the quality of education and learning achievement of learners about environmental knowledge can provide a direct understanding to learners about the environment by applying the concept of vertical garden in the yard of the school. Vertical concept of this garden becomes an alternative in getting around the yard or narrow land. The school plays an important role in this devotion program at the time of making the garden vertical garden, where the school proposes the implementation of maintenance activities and planting new plant species in the annual plan of SDN 34 Kota Ternate. Socialization and workshops that have been done with the school together with community service team Unkhair can provide an early description of the use of a narrow school yard by applying the garden vertical garden. Another target of this program is that students and teachers feel the benefits of this school park in classroom learning so that they can apply the concept of farming obtained for the home.

Abstract

A geophysical research has been conducted to determine the level of hazard vulnerability in West Halmahera by using microtremor data. Microtremor data are analyzed using the Horizontal to Vertical Spectral Ratio (HVSR) method and it is processed using Geopsy software to know hazard vulnerability level in the region . Data analysis and processing are used as sources of information in physics learning materials using an integrated learning model. Research objectives are to train the students to understand the materials in the fields of study and to enhance other discovery ideas.This research method uses the correlational method and the type of research is experimental research. The research design is an uniquecase research design and the instrument used is tests and questionnaires. The results of this research indicate that the microtremor data using integrated learning models of integrated types have effect on the students’ Mastery of materials in the implementation of physics learning. The effect of the integrated learning model of integrated type on the students’ Mastery of materials on the concepts of vibration and waves is 16% and it is in low category. Whereas, the students' responses to integrated learning model of integrated type are quite fun and it can help to improve their mastery of the material on the concepts of vibration and waves.
