Abstract

This study aims to explore mathematical objects in the Balale’ tradition of the Dayak Salako tribe in Nyarumkop Village and then integrate them into the Creation of Culture-Based Modules. The research method used is the ethnographic method, and the type of research used is qualitative. The Balale’ tradition is one of the habits of the Nyarumkop farmers when working the rice fields collectively and in rotation. The Balale’ tradition aims to strengthen relations between communities, because the community works together in the fields to complete tasks such as clearing land, planting rice, clearing grass, and harvesting rice. The results of the study show that the Balale’ tradition has a direct mathematical object in the form of facts that lie in the people who join the lale’an members, the concept lies in the process of working the rice fields which are carried out in turns, the principle lies in the mindset of the community in carrying it out and the skills lies in the work technique of each member of Lale’an. This research also contains indirect mathematical objects in the form of discipline shown by Lale’an members in carrying out this tradition. Then it is mathematically integrated into the creation of a culturebased SPLDV Module using mathematical concepts.

Abstract

Identifikasi patahan merupakan salah satu langkah awal dalam interpretasi seismic dan menjadi komponen penting dalam pengembangan strategi eksplorasi. Deteksi patahan dilakukan dengan metode analisis multi-atribut. Metode ini diterapkan pada data Lapangan Penobscot Kanada. Atribut seismik yang digunakan sebagai data masukan terdiri dari similarity, spectral decomposition, curvature, dip dan semblance. Pickset yang digunakan pada penelitian ini terdiri dari pickset pada patahan besar dan patahan kecil dengan jumlah pick 400. Data latih yang digunakan pada pelatihan JST adalah penampang seismik pada crossline 1271. Penampang seismik yang digunakan sebagai data uji adalah crossline 1305. Hasil penelitian menunjukan efektifitas yang paling tinggi untuk deteksi patahan dihasilkan pada pelatihan JST dengan kombinasi atribut similarity, spectral decomposition dan semblance. Pelatihan JST pada patahan besar secara visual menghasilkan kualitas deteksi yang lebih baik dibandingkan dengan patahan kecil. Penerapan fault enhancement filter (FEF) menghasilkan penampang seismik yang lebih tajam sehingga mempermudah proses picking dan menghasilkan pelatihan JST yang lebih baik dengan nilai error lebih kecil. Pickset yang sudah dilatih pada crossline 1271 dapat diterapkan pada data uji dengan probabilitas patahan yang makin jelas dan tajam dengan nilai misclassification error 6,98%. Kata kunci: deteksi patahan, jaringan syaraf tiruan, analisis atribut
