Judul: Fishers Household Adaptation Strategies Toward Erosion  Impact
Abstrak: Kenaikan permukaan air laut sebagai akibat dari perubahan iklim dapat mengakibatkan terjadinya abrasi di beberapa wilayah pesisir Indonesia. Berbagai dampak yang ditimbulkan abrasi menyebabkan kerentanan pada rumah tangga nelayan. Struktur nafkah dan tinggi rendahnya tingkat kerentanan menentukan strategi adaptasi yang akan diterapkan rumah tangga nelayan. Menerapkan berbagai macam strategi adaptasi akan mampu membuat rumah tangga nelayan bertahan menghadapi perubahan yang terjadi. Penelitian ini menggunakan pendekatan kuantitatif didukung oleh data kualitatif untuk melihat hubungan antar variabel. Hubungan antar variabel ini secara statistik diolah menggunakan uji korelasi Rank Spearman dengan jumlah responden sebanyak 34 rumah tangga nelayan yang terdampak abrasi. Hasil penelitian yang diperoleh menunjukkan bahwa secara umum karakteristik rumah tangga memiliki hubungan yang signifikan dengan variabel struktur nafkah, tingkat kerentanan dan strategi adaptasi. Lalu, hubungan di antara variabel struktur nafkah, tingkat kerentanan dan strategi adaptasi juga menunjukkan hubungan yang signifikan., The rise of sea level as the impact of climate change could cause erosion in several coastal areas in Indonesia. The livelihood structure and the level of vulnerability determines which adaptation strategies that will be implemented. Implementing various adaptation strategies could help fishers households survive the changes. This research uses quantitative approach supported by qualitative data to understand the correlation between variables. The correlation between variables is statistically were processed using the Rank Spearman’s with the total number of respondents being 34 fishers households that were affected by erosion. The results obtained indicate that in general characteristics of households has a significant correlation with the livelihood structure, level of vulnerability and adaptation strategy. Then, the correlation between the variables of livelihood structure, level of vulnerability and adaptation strategy also shows a significant correlation.

Judul: (Kasus: Nelayan Desa Teluk, Kecamatan Labuan, Kabupaten Pandeglang)
Abstrak: Dampak perubahan iklim seperti meningkatnya permukaan air laut, bertambahnya intensitas terjadinya gelombang pasang, serta terjadinya hujan yang disertai dengan angin kencang berakibat pada terhentinya kegiatan nelayan untuk melaut. Hal tersebut mengharuskan para nelayan melakukan strategi adaptasi guna mencukupi kebutuhan hidupnya. Persepsi nelayan terhadap dampak perubahan iklim dapat memengaruhi bentuk adaptasi yang mereka pilih. Adapun tujuan penelitian ini adalah untuk menganalisis persepsi dan faktor-faktor yang memengaruhi persepsi nelayan terhadap dampak perubahan iklim, menganalisis strategi adaptasi nelayan dalam menghadapi dampak perubahan iklim, serta menganalisis pengaruh persepsi terhadap dampak perubahan iklim pada strategi adaptasi nelayan. Metode penelitian yang digunakan dalam penelitian ini, yaitu metode survei dengan menggunakan pendekatan kuantitatif yang dilengkapi oleh data kualitatif. Data kuantitatif diolah menggunakan uji regresi linear sederhana dengan pemilihan responden yang menggunakan teknik clustered random sampling dengan jumlah responden 45 orang., The impacts of climate change such as rising sea levels, increasing intensity of tidal waves, and rain accompanied by strong winds have resulted in the cessation of fishing activities. This requires fishermen to carry out adaptation strategies to meet their daily needs. Fishermen's perception of the impacts of climate change can influence the form of adaptation they choose. The purpose of this study is to analyze perceptions and factors that influence fishermen's perceptions of the impact of climate change, analyze fishermen's adaptation strategies in dealing with the impacts of climate change, and analyze the effect of perceptions on the impact of climate change on fishermen's adaptation strategies. The research method used in this study is a survey method using a quantitative approach which is complemented by qualitative data. Quantitative data was processed using a simple linear regression test with the selection of respondents using clustered random sampling technique with a total of 45 respondents.

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
