The white pomfret is one of the export commodities and is considered an important economically valuable fish in Indonesia. However, the potential of white pomfret in PPI Pasir has not been fully maximized to support the livelihood of fishermen due to capital-related issues. The objective of this research is to describe the fishing activities and the business feasibility of the white pomfret fishery in PPI Pasir. Additionally, it aims to identify the financing behaviour and source used by the white pomfret fishermen community and formulate financial strategies of the white pomfret fishing business. Data collection was conducted through interviews, field observations, and data gathered from relevant institutions. The respondents for this research were selected through purposive sampling, with a total sample size of 16 fishermen. The results of the research indicates that the white pomfret fishery in PPI Pasir utilizes 1 GT-sized boat with gillnet fishing gear featuring a mesh size of 4.5 to 6.5 inches. The business feasibility analysis showed a profit value of Rp2,658,720.00 and an R/C Ratio of 1.03, indicating that the white pomfret business in PPI Pasir is economically viable and worth continuing. Three financing sources were identified among the fishermen in PPI Pasir: the operational based financing, bank capital financing, and non-formal institution financing. The non-formal institution capital was found to be the most beneficial source of financing for the capture fisheries business in Kebumen

Abstrak: The development of small scale fisheries in Indonesia is not quite grow because of difficult to getting loan. PPI Tanjung Pasir is dominated by small scale long line fisheries. The objective of this research are to describe the fishing unit, productivity and financial feasibility. This research used descriptive method. The result showed that long liner was 3-4 GT wood boat, with lenght: 7.5-10 m, width: 2-3 m, and draft 1-2 m. There were 3 fishermen in one fishing unit. The lenght of long line is 3 000-4 000 m, aproximately the number of hook were 600-1 000. Composition of long line catches were dominated by white snapper (Lates carcarifer). Productivity per trip was 28.09 kg/trip/year, boat productivity was 1.899 ton/GT/year, gear productivity (hook rate) was 0.05 fish/trip/boat, and fisherman productivity was 9.36 kg/man/trip. Based on investment analysis, R/C ratio was 1.11, payback period was 2.36 year, ROI was 42%, NPV Rp30 253 594, IRR 51.30% and Net B/C ratio was 2.01. Refers to productivity and financial analysis, Tanjung Pasir long line business is feasible to be continued and expanded.

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.
