Judul: Stock Status of Yellowstripe Scad Selaroides leptolepis (Cuvier 1833) in Sunda Strait
Abstrak: Ikan selar kuning merupakan salah satu ikan pelagis yang memiliki nilai ekonomis penting dan merupakan salah satu ikan tangkapan dominan di PPP Labuan, Banten. Penelitian ini dilakukan untuk mengkaji stok ikan selar kuning di perairan Selat Sunda guna menentukan alternatif pengelolaan yang tepat dan berkelanjutan. Penelitian dilakukan pada bulan Mei-Oktober 2014 dengan interval waktu pengambilan contoh lebih kurang 30 hari. Data primer yang dikumpulkan adalah panjang total dan bobot basah. Sedangkan data tingkat kematangan gonad (TKG), jenis kelamin, dan bobot gonad diperoleh melalui pembedahan ikan. Ikan selar kuning yang tertangkap didominasi TKG I dan TKG II. Pola pertumbuhan ikan selar kuning betina dan jantan bersifat isometrik. Ikan selar kuning betina memiliki nilai koefisien pertumbuhan 0,87 per tahun, sedangkan ikan jantan 0,51 per tahun. Laju eksploitasi ikan selar kuning betina telah melebihi 0,5, sehingga diduga telah terjadi tangkap lebih di perairan Selat Sunda.

Judul: Kajian Stok Sumber Daya Ikan Selar Kuning Selaroides leptolepis (Cuvier 1833) di Perairan Selat Sunda yang didaratkan di PPP Labuan, Banten
Abstrak: Yellowstripe Scad is one of pelagic fishes has the value of economically important fish catches and is dominant in PPP Labuan. Population of yellowstripe scade feared will decline arrest of conducted in continous. The purpose of this study was to assess the condition of yellowstripe scad in Sunda Strait that include of growth, mortality and exploitation rate. The study is done at PPP Labuan on Juny-October 2013. Fish samples observed reach a 752 with length range between 81-168 mm. Yellowstripe scad have allometric negative growth and a size of first maturity 157 mm. Parameter growth allegedly used method Ford Walford showed growth yellowstripe scade female faster than male with growth rate each of 0,42 and 0,36. The exploitation of yellowstripe scad has exceeded the optimum exploitation rate that yellowstripe scad in Sunda Strait has over exploited. Optimum efforts allegedly used Schaefer model showing of 1089 trip/year with maksimum sustainable yield (MSY) of 1977 tonnes/year and total allowable catch 1423 tonnes/year. Management that can be suggested is setting fishing effort and mesh size more than 6 cm.

Judul: The use of homotopy perturbation methode to solve fuzzy volterra  integral equations
Abstrak: Most phenomena in nature can be explained in mathematical models, such as fuzzy volterra integral equation. The fuzzy volterra integral equation is a nonlinear integral problem, which is usually dificult to solve by an analytical solution. In this paper, fuzzy volterra integral equation is solved using perturbaion homotopy method, which can be written as a power series in p and satisfies a certain homotopy fuction. This manuscript discuss two case studies, i.e. the case of linear and trigonometric kernel function. The result shows that greater approximation order being used, the wider convergence solution area wil be.
