Judul: Kemiskinan Dan Strategi Adaptasi Nelayan Di Pulau Sebuku, Kabupaten Kotabaru, Kalimantan Selatan
Abstrak: Fishers living condition including the poverty that occurred in the fishing communities on small islands not yet widely available. Therefore this study is very important. The objective of this study research are 1) what was the level of poverty in the fishers on the island of Sebuku; 2) how about adaptation strategies undertaken by the fishers residing on the island of Sebuku; 3) what are the factors that influence the level of poverty and adaptation strategies of fishers on the island of Sebuku; 4) what is the attitude of fishers towards regional autonomy policy, the entry of mining companies and climatic conditions on the island of Sebuku. This research was conducted with a combination of quantitative and qualitative methods. Correlations is using rank spearman. Location of the study were purposively selected, Rampa Village and Sekapung Village. Sampling using simple random sampling technique. Based on field research, both in the Rampa Village and Sekapung Village, there were nothing included in the category of very poor and poor households based on criteria of BLT (Bantuan Langsung Tunai), while the relative poverty of poor households was used the criteria of the agreement from Rampa Village and Sekapung Village community. Fishers do various adaptation strategies, especially when a bad season. The majority of respondents have a negative attitude toward the policy of regional autonomy and the companies comers on the Sebuku Island. The result showed a positive correlation between the experience of going to sea with attitudes toward climate conditions (r=0.81) and levels of education with an attitude against the companies comers (r=0.30), but there was a negative correlation between the income level attitudes towards the companies comers (r=0.67) and the experience of going to sea with the attitude towards the companies comers (r=0.23). Other variables have no correlation.

Judul: Factors Affecting The Poverty of Fishermen in Kamalmuara, North Jakarta
Abstrak: Kemiskinan masih terjadi pada nelayan di tengah melimpahnya hasil kekayaan sumber daya laut Indonesia, dimana potensi pesisir dan laut yang begitu besar ternyata belum mampu menyejahterahkan kehidupan nelayan. Hubungan antara nelayan miskin dengan pembangunan wilayah adalah akibat dari kemiskinan nelayan yang berkontribusi terhadap kondisi kemiskinan dan ketertinggalan di wilayah pesisir. Dimana karena nelayan ini tinggal di wilayah pesisir, maka wilayah pesisir ini dikatakan tertinggal dibandingkan dengan wilayah-wilayah lain yang sudah maju. Penelitian ini bertujuan untuk mengetahui tingkat kemiskinan nelayan, menganalisis faktor-faktor yang mempengaruhi pendapatan nelayan sehingga menyebabkan kemiskinan, dan mengetahui peran dan strategi pemberdayaan yang dilakukan oleh stakeholders dalam mengentaskan kemiskinan nelayan di Kelurahan Kamalmuara. Penelitian ini dilakukan dengan cara survei dengan pemilihan responden dilakukan dengan menggunakan teknik stratified-accidental sampling, dengan 87 responden yang diambil secara proporsional per strata. Teknik pengolahan dan analisis data dalam penelitian ini menggunakan analisis tingkat kemiskinan, analisis regresi linear berganda, dan analisis deskriptif kualitatif dengan menggunakan metode studi kasus. Berdasarkan hasil penelitian, tingkat kemiskinan nelayan di Kelurahan Kamalmuara, jika dibandingkan dengan garis kemiskinan Badan Pusat Statistik sebesar 42,5% nelayan, sementara jika dibandingkan dengan garis kemiskinan Bank Dunia, ada 70,1%. Faktor yang memengaruhi pendapatan nelayan di Kelurahan Kamalmuara sehingga menyebabkan kemiskinan adalah ukuran perahu. Masyarakat nelayan menginginkan pemberdayaan masyarakat dari stakeholders dalam pengadaan kapal dengan ukuran GT yang lebih besar, serta alat tangkap dan alat pendeteksi ikan, mengadakan kembali program pelatihan pengolahan hasil perikanan dan non perikanan, peminjaman modal usaha, serta pemberian alternatif kesempatan kerja di luar sektor perikanan., Poverty still occurs among fishermen amid the abundance of wealth of Indonesia's marine resources, where the enormous coastal and marine potential has not improved the welfare of fishermen's lives. The relationship between poor fishermen and regional development results from fishermen's poverty which contributes to poverty and underdevelopment conditions in coastal areas; where because these fishermen live in coastal areas, these coastal areas are lagging compared to other developed areas. This study aims to determine the poverty level of fishermen, analyze the factors that affect fishermen's income causing poverty, and find out the role and empowerment strategies carried out by stakeholders in alleviating poverty in Kamalmuara Urban Village. This research was conducted through a survey with the selection of respondents using stratified-accidental sampling techniques, with 87 respondents taken proportionally per strata. This study's data processing and analysis techniques use poverty level analysis, multiple linear regression analysis, and qualitative descriptive analysis using the case study method. Based on the study results, the poverty rate of fishermen in Kamalmuara Urban Village, when compared to the Central Bureau of Statistics poverty line, is 42,5% of fishermen; compared to the World Bank poverty line, there are 70,1%. The factor that affects the income of fishermen in Kamalmuara Urban Village that causes poverty is the size of the boat. The fishing community wants community empowerment from stakeholders in procuring vessels with larger GT sizes, fishing gear, and fish detection equipment, re-holding training programs for processing fishery and non-fishery products, lending business capital, and providing alternative employment opportunities outside the fisheries sector.

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.
