Abstract

Most people are only familiar with functions that have been formulated explicitly y=f(x)) or implicitly (f(x,y)=0) However, functions obtained by researchers and engineers based on experimental data or field observations often do not have a known formula, and are therefore only represented in the form of tabulated discrete points. To determine the continuity of a tabulated function obtained from observational data, a function formula from the data is required. Consequently, the condition for the continuity of a function, where 〖lim〗┬(x→c)⁡〖f(x)=f(c)〗cannot be met. The problem in this research is to utilize data on the number of poor people from 2015-2021 and predict the monthly number of poor people using the Newton polynomial interpolation method with Maple. It also aims to prove the continuity of functions represented by tabulated discrete points by showing whether 〖lim〗┬(x→c)⁡〖p(x)=p(c)〗 or 〖lim〗┬(x→c)⁡〖p(x)≠p(c)〗. Based on the research results, it was found that Newton polynomial interpolation can be used to estimate the monthly number of poor people based on annual data, provided the conditions are met: the data represents a function, and the data table interval is changed to (1 )/12. The estimated function (Newton polynomial) p(x) obtained, in the form: (0.0121666) x^5-(122.7059942) x^4+ ( 4.950193546*〖10〗^5 ) x^3-( 0.985008654*〖10〗^8 ) x^2+(1.0070 35027*〖10〗^12)x-(4.062567218*〖10〗^14 ) has been proven to demonstrate the continuity of a function represented by tabulated discrete points by showing that 〖lim〗┬(x→c)⁡〖p(x)=p(c)〗 for each point.

Abstract

Penelitian ini dilaksanakan Kelurahan Sasa, Kec. Ternate Selatan, Kota Ternate, Provinsi Maluku Utara pada bulan Febuari 2023, dengan tujuan untuk menjelaskan, mengevaluasi dan merumuskan model strategi dan sistem penanganan ikan layang pada kapal purse seine KM. Woka Ruju 01. Penggunaan metode observasi, wawancara dan deskriptif kualitatif, dengan data penelitian yang diambil berupa data primer dan data sekunder secara purposive sampling yang kemudian diolah dengan pendekatan SWOT untuk merumuskan strategi penanganan ikan layang yang baik agar terjada kualitas mutunya sampai pada proses pemasaran. Hasil pra-analisis nilai skor IFSF adalah 2.68 yang menunjukan kondisi internal memiliki kekuatan untuk mengatasi situasi atau masalah yang dihadapi oleh nelaya, sedangkan nilai skor EFSF adalah 2.82 yang artinya ancaman dari system penanganan hasil tangkapan maih mampu diatasi dengan memanfaatkan peluang. Kondisi hasil sistem penanganan hasil tangkapan ikan pada kapal KM. Woka Ruju 01 berada pada sel IV yang menunjukan bahwa system SWOT berada pada posisi growth dan stability dimana kondisi ini mngindikasikan mutu hasil tangkapan masih cukup baik tetapi harus ada upaya perbaikan oleh nelayan dengan meminimalkan kelemahan dan mengatasi ancaman.
