Pengaruh Suhu Udara, Curah Hujan, dan Luas Lahan terhadap Produksi Kopi di Kabupaten Deli Serdang dengan Menggunakan Metode Analisis Jalur

Abstract

This research was conducted to see the effect of air temperature, rainfall, and land area on coffee production in Deli Serdang Regency. The data analysis technique used in this study is path analysis. The exogenous variables used are air temperature, rainfall, and land area. And the endogenous variable used is coffee production. The data used is secondary data from 2012-2022 taken online from the official BPS website. Techniques and analysis with path analysis were carried out to see how much influence air temperature, rainfall, and land area have on coffee production. The path analysis method produces a path equation Y = 0.036X_1 + 0.177X_2 + 0.855X_3 + 0.427 meaning that as air temperature and rainfall increase, coffee production will decrease. Meanwhile, the area of land with coffee production is inversely proportional, meaning that the more land area used, the higher the amount of coffee production. Air temperature, rainfall, and land area contribute together to coffee production, namely 81.8% and 18.2% influenced by other variables outside the path model.
