Abstract

Birds, or avians, are living organisms classified in the animal kingdom and share characteristic features such as a body covering of feathers that enables them to fly. Birds are also a biodiversity asset that needs to be conserved and preserved due to their significance and roles in human life. Samudra University, with its expansive grounds adorned with various trees, provides a potential habitat for birds. This research, conducted in October-November 2023, aims to explore the diversity of bird species within the Samudra University area. The study employs a quantitative descriptive method, covering four locations, Location I in the Faculty of Agriculture, Location II by the sea, Location III in the Student Building, and Location IV in the Faculty of Primary School Teacher Education. The findings reveal four avian species from four families in the Samudra University area: Passer montanus, Ardea alba, Geopelia striata, and Todirhampus chloris. The avian diversity index in that area is considered moderate.

Abstract

Starch is a type of polysaccharide formed from the polymerization of glucose. Starch is also known as starch which is a widespread reserve polysaccharide in plants. Starch is also defined as a complex carbohydrate which is very important as a food source. The purpose of this research is to determine the shape and type of starch in the tuber family. This research was conducted using descriptive methods. The purpose of this study is to describe and describe the characteristics of the forms and types of starch.Based on the results of observations, it can be concluded that the starch in taro, cassava, porang and jicama tubers has a concentric type and has regular and irregular round shapes, while potato tubers have an eccentric type and are oval or oblong in shape.Potato tubers have the highest starch of the five tubers because potatoes have a dense starch structure and contain a lot of starch or starch.
