Abstract

This research aims to determine the relationship between light intensity and beam distance as the inverse square law. From the experimental results it was found that the relationship between light intensity with the distance of the beam that is the farther the distance of the beam used, the intensity of the light obtained will be smaller, and vice versa. From the results of research conducted, obtained results for an average light intensity of 2.0636 Cd.

Abstract

This study aims to develop locally sourced, self-produced feed for Nile tilapia (Oreochromis niloticus) in Kokoda District, West Papua, to reduce high production costs due to reliance on commercial feed. A survey of local raw materials identified the potential use of sago flour, sembilang fish, shrimp heads, and banana peels as feed ingredients. The feed formulation was designed with a protein content of 31% and tested through proximate analysis and a 42-day growth trial of Nile tilapia using a Completely Randomized Design (CRD) compared to commercial feed. Results showed that self-produced feed resulted in lower weight and length growth compared to commercial feed, with higher feed conversion ratio (FCR) efficiency in commercial feed. However, the self-produced feed still demonstrated potential as an economical alternative with nearly equivalent fish survival rates. The study concludes that with further adjustments, self-produced feed can become a sustainable solution for tilapia farmers in remote areas.
