Indonesia will be projected to be maritime axis in the world. Indonesian potential as a maritime country inspires Nawacita vision established by Joko Widodo in his cabinet. This ambitions must be supported by coastal communities. The province of West Sulawesi has a long coastal territory than other provinces in Indonesia. It should be exploited to promote the realization of Nawacita for the better Indonesia in the future. In education sector, 2013 curriculum introduces that teachers must implement scientific approach to their learning. Physics is one of the subjects that is still considered difficult by students. It will be more complex when it is taught by scientific approach. In other hand, physics is one of the most important subjects in preparing high school students for their job in science and technology. Contextual learning could be a solution in delivering physics to students. Without forgetting the 2013 curriculum, physics learning in the context of ocean literacy owned by West Sulawesi can lead students to gain meaningful experience. Based on these considerations, this article will discuss how to integrate ocean literacy into physics learning.

Simulation of radiation calculation of black body by using the interpolation method is designed to facilitate the determination of radiation in black matter efficiency. Fortran programming languages are chosen for computational processes. The calculation program that has been designed is able to calculate the efficiency of black body radiation easily and quickly with a fairly small error rate of 0.5\%. The light radiation spectrum of objects is around 1000, 1100, 1200, and 1300 $^{\circ}$C. The $x$ axis shows the wavelength, while the $y$ axis shows the intensity or strength of light. If we pay attention to the curvature of 1000 $^{\circ}$C, along with the increasing frequency of light, the intensity of light is also getting stronger aka more bright. But at certain light frequencies, the line reaches the peak, and after that the light intensity drops dramatically. At temperatures of 1200 $^{\circ}$C and 1300 $^{\circ}$C, even though the temperature rises, the outline of the line graph is similar to the line 1000 $^{\circ}$C. This is in accordance with the existing theoretical and experimental results.
