Judul: Pengaruh Pola Adaptasi terhadap Kesejahteraan Masyarakat Nelayan di Desa Ujung Alang, Kecamatan Kampung Laut, Kabupaten Cilacap
Abstrak: Coastal and marine resources is a very important asset for the life of fishermen. Changes in coastal and marine resources will certainly affect the life activities of fishermen. Fishermen should be able to adapt to meet the needs of life can be maintained. Adjustment or adaptation actions will certainly have an impact on the welfare of fishermen. The purpose of this study was to observe the effect of the pattern of adaptation to the welfare of fishermen. This study used a quantitative approach and the qualitative approach supported. The data collected are primary data and secondary data. Quantitative approach using regression test. Meanwhile, a qualitative approach using in-depth interview approach. The results showed that the pattern of adaptation does not affect the welfare of the fishermen of the fishing life. This is because the majority of the fishermen of the adaptation pattern is still reactive and has not been able to meet the needs of fishermen.

Judul: Pengaruh eksistensi kearifan lokal hajat laut terhadap kesejahteraan ekonomi dan sosial masyarakat nelayan di Pangandaran
Abstrak: Sumberdaya pesisir dan laut merupakan aset yang sangat penting bagi kehidupan nelayan. Perubahan yang terjadi pada sumberdaya pesisir dan laut sudah tentu akan mempengaruhi aktivitas kehidupan nelayan. Nelayan harus dapat melakukan adaptasi agar pemenuhan kebutuhan hidupnya dapat tetap terjaga. Tindakan penyesesuaian atau adaptasi ini tentu akan memiliki dampak terhadap kesejahteraan nelayan. Tujuan dari penelitian ini adalah untuk melihat pengaruh pola adaptasi terhadap kesejahteraan nelayan. Penelitian ini menggunakan pendekatan kuantitatif dan dengan didukung pendekatan kualitatif. Data yang dikumpulkan adalah data primer dan data sekunder. Pendekatan kuantitatif menggunakan uji regresi. Sementara itu, pendekatan kualitatif menggunakan pendekatan wawancara mendalam. Hasil penelitian menunjukkan bahwa pola adaptasi yang dilakukan nelayan tidak mempengaruhi kesejahteraan hidup nelayan. Hal ini dikarenakan mayoritas pola adaptasi yang dilakukan nelayan masih bersifat reaktif dan belum mampu untuk memenuhi kebutuhan hidup nelayan.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
