Abstract

This research aims to analyze the impact of economic growth, population, energy consumption, and Human Development Index (HDI) on Carbon Dioxide (CO₂) emissions in 11 ASEAN countries during the period 2013–2021. The research applies a dynamic panel regression method using the Generalized Method of Moments (GMM) approach. The research results indicate that although Economic Growth (GDP) has a positive yet insignificant impact in the short term, it shows a weak and positive impact in the long term, indicating continued reliance on fossil energy that has not been separated completely from economic growth. Population (POP) has a positive and significant impact on CO₂ emissions, both in the short and long term, indicating that increasing population leads to higher energy demand and greater economic activity. Energy Consumption (ERG) has an insignificant impact, due to the diversity of energy sources, including renewable energy, or measurement inefficiencies. The Human Development Index (HDI) has a negative and significant impact, especially in the long term, showing that improving human quality through education, health, and the economy can promote sustainable development and reduce CO₂ emissions. The policy implications of this research include controlling the impact of population through sustainable urban planning, strengthening environmentally based Human Development, decarbonizing economic growth, and implementing long-term strategies such as regional collaboration for a clean energy transition. These findings contribute theoretically to the advancement of the Environmental Kuznets Curve (EKC) model.

Abstract

Penelitian ini bertujuan untuk menganalisis dan mengoptimalkan pengendalian persediaan bahan baku pada Izzi Kebab yakni sebuah UMKM kuliner di Medan yang selama ini masih mengandalkan estimasi intuitif dalam pengadaan barang. Pola pengadaan konvensional tersebut menyebabkan frekuensi pemesanan yang terlalu tinggi dan pembengkakan biaya operasional. Untuk mengatasi permasalahan tersebut, penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan menerapkan metode Economic Order Quantity (EOQ) dan Reorder Point (ROP) yang diolah menggunakan aplikasi POM QM for Windows. Hasil analisis menunjukkan bahwa melalui metode EOQ, Izzi Kebab dapat melakukan transformasi manajemen persediaan yang signifikan dengan merampingkan frekuensi pemesanan dari 52 kali setahun menjadi rata-rata 4 hingga 11 kali saja. Secara spesifik, kuantitas pemesanan optimal (Q*) untuk daging kebab adalah 27,93 kg, tortilla 64,5 unit, selada 48,72 kg, timun 48,37 kg, saus cabai 62,45 kg, serta saus tomat dan mayonaise masing-masing sebesar 44,16 kg. Implementasi strategi ini terbukti mampu menyeimbangkan biaya pesan dan biaya simpan pada titik terendah, sehingga menghasilkan total biaya persediaan yang lebih efisien dan stabil. Kesimpulannya, penggunaan metode ilmiah berbasis teknologi ini memberikan rekomendasi strategis bagi Izzi Kebab untuk meningkatkan efisiensi modal kerja dan keberlanjutan operasional bisnis UMKM.
