Abstract

This study examines the projected population in Pohuwato Regency in the future in 2035 using the Arithmetic method. Given that the presentation of projection data is generally only in the form of tables and graphs, the purpose of this study is to present complete projection data both in the form of tables, graphs and visually in the form of maps. The research method used is quantitative analysis. The results of the study show that the projected population of Pohuwato Regency in 2034 is estimated arithmetically to be 191,499 (people). Based on the map visualization, there are 3 classes, namely low, medium and high. The low classification is Wanggarasi, Dengilo, Taluditi, West Popapato, East Popayato, and Popayato. The classification of the projected medium population is Buntulia, Duhiadaa, Lemito, Paguat, and Patilanggio Districts. As for the projection of high population, is Marisa and Randangan Districts.

Abstract

Penelitian ini bertujuan untuk menganalisis kadar antosianin pada jagung lokal Gorontalo varietas Binthe Kiki, Binthe Momala, dan Binthe Pulo. Metode yang digunakan adalah penelitian deskriptif kuantitatif dengan teknik ekstraksi dan pengukuran antosianin menggunakan metode pH diferensial pada panjang gelombang 530 nm dan 700 nm. Hasil penelitian menunjukkan bahwa ketiga varietas mengandung antosianin dengan kadar yang bervariasi, yaitu Binthe Kiki sebesar 9,00 ppm, Binthe Momala sebesar 3,77 ppm, dan Binthe Pulo sebesar 3,13 ppm. Kandungan antosianin tertinggi ditemukan pada varietas Binthe Kiki, yang ditandai dengan warna biji orange. Perbedaan kadar antosianin antar varietas dipengaruhi oleh faktor genetik, warna biji, dan kondisi lingkungan. Temuan ini menunjukkan bahwa jagung lokal Gorontalo, khususnya varietas Binthe Kiki, berpotensi sebagai sumber pewarna alami sekaligus antioksidan bagi kesehatan manusia.
