Judul: The correlation between climate change adaptation strategy with the income level of traditional fishermen.
Abstrak: Dampak perubahan iklim bukan hanya pada kondisi ekologis sekitar, namun juga pada sektor perikanan tangkap yang menyebabkan terjadinya perubahan perilaku pada nelayan. Perubahan perilaku tersebut dimaksudkan untuk dapat beradaptasi dari perubahan iklim yang terjadi. Oleh karena itu, tujuan penelitian ini akan menganalisis strategi adaptasi perubahan iklim pada nelayan tradisional, menganalisis tingkat pendapatan nelayan tradisional, dan menganalisis hubungan strategi adaptasi perubahan iklim dengan tingkat pendapatan nelayan tradisional di Kelurahan Pulau Kelapa, Kepulauan Seribu Utara, Kabupaten Kepulauan Seribu, DKI Jakarta. Data kuantitatif diperoleh melalui wawancara terstruktur dengan menggunakan kuesioner yang diberikan kepada responden sedangkan data kualitatif diperoleh melalui metode wawancara mendalam dengan informan dan observasi lapang. Responden dipilih sebanyak 45 responden menggunakan teknik accidental sampling dan informan ditentukan menggunakan teknik bola salju (snowball). Penelitian ini menemukan bahwa terdapat hubungan antara strategi adaptasi yang dilakukan nelayan dengan tingkat pendapatan nelayan tradisional, yang ditunjukan semakin tinggi strategi adaptasi yang dilakukan nelayan tradisional akan semakin tinggi tingkat pendapatan nelayan tradisional., The impact of climate change is not only on the surrounding ecological conditions, but also on the capture fisheries sector which causes changes in behavior among fishermen. These changes in behavior are intended to be able to adapt to climate changes that occur. Therefore, the aim of this research is to analyze climate change adaptation strategies for traditional fishermen, analyze the income level of traditional fishermen, and analyze the relationship between climate change adaptation strategies and the income level of traditional fishermen in Pulau Kelapa Village, North Seribu Islands, Seribu Islands Regency, DKI Jakarta. Quantitative data was obtained through structured interviews using questionnaires given to respondents, while qualitative data was obtained through in-depth interviews with informants and field observations. 45 respondents selected using an acidental sampling sampling technique and informants will be determined using the snowball technique. This research found that there is a relationship between the adaptation strategies used by fishermen and the income level of traditional fishermen, which shows that the higher the adaptation strategies used by traditional fishermen, the higher the income level of traditional fishermen.

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.
