Abstract

Energi panas bumi merupakan salah satu sumber energi alternatif yang baru dan terbarukan serta ramah lingkungan.Sulawesi Utara diketahui kaya akan energi panas bumi karena memiliki banyak gunungapi aktif yang membentuk sistem panas bumi di bawah permukaan. Pembentukan sistem panas bumi dipengaruhi oleh proses-proses geologi yang telah atau sedang berlangsung di sepanjang jalur gunung api. Penelitian ini bertujuan untuk mengetahui tingkat densitas kelurusan di daerah Bukit Kasih Kanonang dan mengetahui komposisi mineral batuan di daerah Bukit Kasih Kanonang.Penelitian ini dilakukan dalam rangka mendorong percepatan capaian renstra penelitian perguruan tinggi dalam menghasilkan temuan/metode/teori, khususnya dibidang energi dan kebumian. Lokasi penelitian yang diteliti terletak di daerah wisata Bukit Kasih Kanonang, Kecamatan Kawangkoan Barat, Kabubaten Minahasa, Provinsi Sulawesi Utara. Data yang di ambil berupa data citra SRTM untuk mendapatkan data tingkat densitas kelurusan (lineament) pada manifestasi panas bumi. Sampel batuan yang diambil di lapangan di analisis di laboratorium dengan menggunakan alat SEM-EDX. Hasil enelitian menunjukkan bahwa densitas struktur dengan nilai yang tinggi berasosiasi dengan adanya manifestasi panas bumi di permukaan. Densitas kelurusan di daerah Bukit Kasih Lahendong memiliki kepadatan yang cukup tinggi sehingga ditandai dengan munculnya beberapa manifestasi permukaan di beberapa titik antara lain batuan alterasi, dengan komposisi unsur Batuan sample 1 mengandung Karbon 63,28 %, Oksigen 35,33 dan Silika 1,40%. Pada sample batuan 2 mengandung Oksigen 69,49 %, Silika 30,51%.

Abstract

Tsunami is a serious threat to the island nation such as Indonesia. The tsunami disasters that were occurred in some parts of Indonesia have immerged the need for tsunami early warning system that is reliable and can be applied to the Indonesian archipelago. North Sulawesi is one of the areas prone to tsunamis since this area lies in the path called the ring of fire's. This article describes a tsunami simulation application for the north coast of North Sulawesi. Web-based applications were built so that they can be monitored online from anywhere and at anytime. This system reads the real-time seismic data that affect the North Sulawesi region from a number of sources. Dynamic and static data that are received are processed using data mining method to predict the chances of a tsunami, while flood flooding algorithm is used to visualize the map of affected areas of North Sulawesi. The resulting information is available in detail in the form of web pages and also through short message to the relevant authorities handling of the tsunami disaster in order for them to act in accordance with applicable standard operating procedures. With this application, the public can obtain information that is more accurate. Relevant authorities can conduct tsunami disaster mitigation measures more effectively.
