Gross Regional Domestic Product is one of the good indicators to measure the economy of a region. In this study, GRDP modeling was conducted with the independent variables of the employed workforce (X1) and the number of job training institutions (X2) using spatial regression and Ordinary Least Square (OLS). The purpose of this study was to determine the spatial regression model of GRDP with these two predictors or independent variables, to determine the interaction of the proximity of districts/cities with neighboring districts/cities, and to determine the effect of the employed workforce (X1) and the number of job training institutions (X2) on the GRDP value. The results showed that based on the Robust Lagrange Multiplier test, the appropriate spatial regression was the SAR model. The coefficient of determination and MAPE in the OLS model were 57.8% and 1.888, while in the spatial regression model were 68.72% and 0.4139. These results indicate that spatial regression is better than OLS in modeling GRDP in East Java, because the coefficient of determination of the spatial regression model was larger and the MAPE was smaller than the OLS model. The interaction of the proximity of a district/city with neighboring districts/cities indicates that the district/city economy is influenced by the economy of neighboring districts/cities. The two independent variables, namely the employed workforce (X1) and the number of job training institutions (X2) have a positive influence on the GRDP value.

PENGUKURAN KINERJA PROSES RANTAI PASOK HIJAU DENGAN PENDEKATAN GREEN SCOR PADA DISTRIBUTOR PRODUK PERALATAN MEDIS
Dalam era industri saat ini, keberlanjutan menjadi aspek krusial dalam mengelola operasional perusahaan. Fokus penelitian ini adalah pada rantai pasok produk medis habis pakai yang didistribusikan oleh sebuah perusahaan distributor peralatan kesehatan. Produk medis habis pakai memiliki siklus pemakaian singkat, berpotensi memberikan dampak signifikan terhadap lingkungan. Produk ini sering menghadapi masalah seperti penuaan inventaris, yang meningkatkan risiko produk kedaluwarsa karena kurangnya penjualan, dan akhirnya dapat berujung pada penumpukan limbah. Selain itu, peningkatan emisi CO2 yang disebabkan oleh transportasi yang tidak ramah lingkungan memberikan dampak negatif tambahan pada lingkungan. Solusi untuk mengatasi permasalahan ini melibatkan implementasi pengukuran kinerja rantai pasok hijau. Penelitian ini bertujuan memberikan rekomendasi perbaikan pada setiap tahap rantai pasok menggunakan metode Green SCOR (Green Supply Chain Operation Reference) untuk mendekomposisi proses, dan AHP (Analytical Hierarchy Process) untuk memberikan bobot pada hierarki KPI. Hasil penilaian dengan Objective Matrix dan Traffic Light System menunjukkan bahwa hasil dari pengukuran kinerja GSCM secara keseluruhan adalah 5,482 yang berarti performa perusahaan dikatakan cukup dan membutuhkan perbaikan untuk mencapai target maksimum. Terdapat 10 indikator kinerja yang sudah baik, 4 indikator kinerja yang belum maksimal dan 4 indikator kinerja yang memerlukan perbaikan guna meningkatkan kinerja perusahaan. Perbaikan ini menjadi krusial untuk memastikan keselarasan rantai pasok dengan prinsip-prinsip lingkungan dan berkontribusi pada keberlanjutan usaha.
