Abstract

The selection of superior food crop commodities at the regional level is very important to sup-port agricultural development policies, but it is often carried out without comprehensive strategic analysis, risking less accurate decisions. The objective of this research is to establish the superior commodities of the food crop subsector in Langkat Regency based on regional contributions and a number of strategic criteria. The methods used include Location Quotient (LQ) to measure the region's comparative advantage based on production contribution, as well as Fuzzy ARAS to evaluate seven commodities based on ten strategic criteria with expert assessment using triangular fuzzy numbers. The results show that rice is the base commodity in 13 districts and has the highest contribution distribution. However, soybeans have become the superior commodity with the highest relative utility value (1.029), followed by cassava (1.015) and rice (0.983). The LQ and Fuzzy ARAS methods have proven effective in supporting the de-termination of superior commodities based on local potential.

Abstract

Penelitian menganalisis hubungan antara pertumbuhan UMKM dan penurunan tingkat pengangguran di Sumatera Utara dengan menggunakan model eksponensial dan logistik. Berdasarkan data dari periode 2020 hingga 2023, model eksponensial menunjukkan bahwa jumlah UMKM tumbuh dengan laju rata-rata sebesar 4,96% per tahun. Sementara itu, model logistik yang digunakan untuk memprediksi penurunan pengangguran menunjukkan bahwa UMKM berkontribusi dalam mengurangi Tingkat Pengangguran Terbuka (TPT) sebesar 1,42% per tahun. Hasil analisis korelasi Pearson menunjukkan adanya korelasi negatif yang sangat kuat (-0,87) antara pertumbuhan UMKM dan penurunan pengangguran. Secara keseluruhan, efektivitas UMKM dalam menyerap tenaga kerja tercatat mencapai 75%, khususnya dalam mengurangi pengangguran di kalangan usia muda (15–24 tahun).
