Abstract

The volatility of quarterly Gross Regional Domestic Product (GRDP) growth across economic sectors poses a significant challenge for regional governments in determining investment priorities. This study develops a decision support system (DSS) to rank investment priorities among economic sectors in West Sumatra Province using a hybrid Analytic Hierarchy Process–Technique for Order Preference by Similarity to Ideal Solution (AHP-TOPSIS) method. Five criteria were extracted from three dimensions of GRDP growth rates, namely C-to-C, Q-to-Q, and Y-on-Y, for 2024–2025: average C-to-C growth, average Y-on-Y growth, Q-to-Q stability (the inverse of standard deviation), latest quarter growth (Q4 2025), and positive consistency (the number of quarters with growth > 0). Criteria weights were determined through an AHP pairwise comparison questionnaire completed by regional economic experts, resulting in a consistency ratio (CR) of 0.015. The TOPSIS method was then applied to rank 17 economic sectors. The results show that the top five investment priorities are Government Administration, Defense, and Mandatory Social Security (O) = 0.711; Health Services and Social Activities (Q) = 0.671; Financial Services and Insurance (K) = 0.633; Other Services (R) = 0.594; and Real Estate (L) = 0.573. The system was implemented as an interactive dashboard using Python Streamlit. The ranking results are consistent with regional development conditions, as validated by experts. This DSS provides an objective, data-driven tool for regional investment policymaking.

Abstract

Perkembangan kecerdasan buatan (AI) yang pesat membawa tantangan baru dalam dunia pendidikan, khususnya terkait literasi digital dan etika penggunaannya di kalangan siswa sekolah menengah. Kegiatan pengabdian ini bertujuan untuk meningkatkan literasi digital dan pemahaman etika penggunaan kecerdasan buatan (AI) pada siswa MTs N 5 Kuranji, Kota Padang, sebagai upaya preventif terhadap penyalahgunaan teknologi di era AI. Program ini menggunakan pendekatan pelatihan interaktif berbasis pengalaman (experiential learning) yang melibatkan 20 siswa dan beberapa orang guru sebagai co-fasilitator. Kegiatan dilaksanakan melalui lima tahapan, yaitu : persiapan, sosialisasi, pelatihan interaktif (diskusi, simulasi, role-play, studi kasus), pendampingan dan evaluasi menggunakan pre-test dan post-test, serta keberlanjutan program. Efektivitas program diukur menggunakan analisis N-Gain dan kuesioner kepuasan peserta. Hasil kegiatan menunjukkan peningkatan pemahaman siswa yang signifikan, dengan rata-rata skor pre-test 9,6 meningkat menjadi 16,1 pada post-test (skor maksimum 20). Nilai N-Gain sebesar 0,65 termasuk dalam kategori sedang, yang menunjukkan efektivitas metode pelatihan. Tingkat kepuasan peserta berada pada kategori tinggi (rata-rata 3,6 dari skala 4). Program pelatihan interaktif terbukti efektif dalam meningkatkan literasi digital dan etika AI siswa madrasah tsanawiyah, sekaligus memberikan kontribusi nyata dalam pembentukan karakter digital yang bertanggung jawab.
