Conformal mapping of unbounded multiply connected regions onto canonical slit regions

We present a boundary integral equation method for conformal mapping of unbounded multiply connected regions onto five types of canonical slit regions. For each canonical region, three linear boundary integral equations are constructed from a boundary relationship satisfied by an analytic function on an unboundedmultiply connected region. The integral equations are uniquely solvable. The kernels involved in these integral equations are the modified Neumann kernels and the adjoint generalized Neumann kernels

Kkn-ppm Sebagai Akselerator Pemanfaatan Potensi Sumberdaya Alam Desa

Desa dikenal sebagai sebuah komunitas yang diatur dalam lingkup administratif kewilayahan. Desa terkebelakang dan tertinggal diakibatkan oleh wilayah yang terpencil dan terisolir, kebanyakan berada pada dataran tinggi atau pegunungan. Kategori ini merupakan kategori Desa Salo Dua, Kecamatan Maiwa, Kabupaten Enrekang yang menjadi lokasi pelaksanaan KKN-PPM Universitas Islam Makassar. Persamalah-permaslahan yang dihadapi masyarakat Desa Salo Dua antara lain lahan sawah didominasi oleh lahan tadah hujan sehingga produksi tanaman pangan utamanya padi belum optimal, terdapat lahan terlantar yang cukup luas utamanya yang tidak termanfaatkan oleh warga masyarakat, pemeliharaan ternak yang masih tradisional, limbah ternak dan limbah peranian belum dimanfaatkan untuk memproduksi produk-produk ekonomis seperti pupuk organik dan biogas serta pembuatan gula merah dilakukan dengan teknologi manual sederhana. Tujuan KKN-PPM ini adalah meningkatkan kapasitas masyarakat dalam memanfaatkan sumberdaya alam untuk meningkatkan kesejahteraannya. Kegiatan-kegiatan mahasiswa KKN-PPM yang dilaksanakan antara lain peningkatan produksi, efisiensi, peningkatan partisipasi, perbaikan system dan peningkatan swadana dan swadaya masyarakat. Kegiatan tersebut dilakukan dengan motode pelatihan in-situ maupun sekolah lapang, seperti peningkatan produksi dengan pemanfaatan lahan kering, introduksi teknologi pengolahan gula aren, introduksi teknologi inseminasi buatan terhadap ternak sapi, pembuatan instalasi biogas

Inventarisasi Kearifan Lokal Ghatib Beghanyut Masyarakat Siak Sri Indrapura

The tradition of rejecting reinforcements for the Siak community and an intangible cultural heritage that needs to be preserved by taking an inventory.

Karakterisasi Zona Reservoar Cekungan Bula Maluku dengan Metode Elektromagnetik Magnetotellurik

The research have been realize with using the electromagnetic telluric for reservoir characterization of hydrocarbon. The Research area is located in Bula Seram which is the eastern part of Maluku Province. Base on map of the tectonic plate Seram island, area is sedimentary basins that is potential of hydrocarbons. The method used to predict the potential of sedimentary basins that magnetotelluric method to identificate of reservoir zone. This study uses secondary data of MT with two line, each line consisting of seven measurement points. The processed data shows 1D model that display the number of layers for each measurement points and 2D model that display the structure of subsurface resistivity. Analysis and interpretation model showed that the reservoir zone is located in a depth of 2500 - 4000 meter with resistivity values is about 32-1024 Ohmmeter supported by manifestation of oil on the surface, the geological information area of research and information from previous studies
