Abstract

Transformasi ekonomi Kota Padang telah mengakselerasi industrialisasi, pertumbuhan demografis, dan motorisasi yang berimplikasi pada degradasi kualitas udara ambien. Eskalasi kasus infeksi saluran pernapasan akut (ISPA) selama periode 2020-2024 mengindikasikan urgensi evaluasi komprehensif terhadap kontaminan atmosferik sebagai basis formulasi strategi mitigasi pencemaran. Metode deskriptif-kuantitatif dilakukan di sepuluh titik sampling representatif untuk mengevaluasi parameter kualitas udara. Hasil menunjukkan status kualitas udara Kota Padang masih memenuhi standar PP No. 22 Tahun 2021 dengan seluruh parameter SO₂ (32,2-102 μg/m³), NOₓ (31,1-86,2 μg/m³), CO (1.214-4.296 μg/m³), dan PM₁₀ (0,17-15,3 μg/m³) dalam kategori ISPU "Baik", dimana analisis regresi mengidentifikasi 73,4% variasi konsentrasi polutan dipengaruhi oleh intensitas pembangunan, dinamika demografis-sosial, dan densitas lalu lintas dengan heterogenitas spasial signifikan yang menunjukkan konsentrasi maksimal di RTH Imam Bonjol, Terminal Anak Aia, dan Jalan Raya Indarung sebagai koridor dengan aktivitas antropogenik intensif dan mobilitas tinggi. Rapid urban modernization and economic growth in Padang City have contributed to the degradation of ambient air quality, posing potential risks to public health. This study aims to evaluate the concentrations of key air pollutants—SO₂, NOₓ, CO, and PM₁₀—and to identify dominant influencing factors. A quantitative descriptive approach was applied to ten sampling points representing diverse activity zones. Results indicate that all parameters met the national ambient air quality standards (PP No. 22/2021) and were classified as “Good” by the Air Pollution Standard Index (ISPU): SO₂ (32.2–102 μg/m³), NOₓ (31.1–86.2 μg/m³), CO (1,214–4,296 μg/m³), and PM₁₀ (0.17–15.3 μg/m³). Regression analysis revealed that 73.4% of pollutant concentration variance was significantly influenced by infrastructure development, demographic growth, and traffic density. Spatial heterogeneity highlighted pollution hotspots at Imam Bonjol Green Open Space, Anak Aia Terminal, and Jalan Raya Indarung, which should be prioritized in future urban air quality mitigation strategies.

Abstract

MDM is a trade cooperative business unit that supplies healthy food options for consumers around the Andalas University campus. So far, the selection of suppliers that provide supply goods to the stores is only based on the trust between both parties, which is the principle of mutual acquaintance and kinship. The problems that may arise from a process like this are the lack of the right supplier, unavailability of goods, relatively higher product prices, late delivery, and low-quality goods. Therefore, we need a GDSS that is capable of overcoming these problems. This GDSS helps in decision-making by determining the right supplier for each of the stores owned by the MDM Cooperative. The methods used are AHP, TOPSIS, and BORDA, involving six criteria and five tested alternatives. The AHP method is used to obtain the weight of each criterion taken from the pairwise comparison matrix. The TOPSIS method is used to determine which suppliers get priority for supply goods. Combining the AHP and TOPSIS methods can reduce the weaknesses of the TOPSIS itself by giving subjective weights. The use of the BORDA method can provide maximum results in selecting this supplier. This GDSS also involves three decision-making bodies: the head of the cooperative, the deputy, and the treasurer. The results of this prototype can show the best alternative selected based on the ranking method.

Abstract

The industrial sector's growth has led to an increase in the number of industrial products available in the market. However, this has made it more challenging for retail merchants to choose which items to sell due to the overwhelming number of options. The seller must carefully consider various factors such as the type, quality, and probability of selling the goods to turn a profit. This research proposes a group decision support system to assist retail sellers in selecting the products to sell. The system is designed to process various information on comparing retail products against specific criteria, enabling sellers to make quick and accurate decisions. To achieve optimal results, this study combines three methods in the decision-making calculation process: Fuzzy Logic, EDAS, and Borda methods. The Fuzzy Logic method is used to assign a value to an unclear criterion, followed by the EDAS method ranking process, and ending with the combination of the decision-making results using the Borda method. The group decision support system is web-based and has been proven to provide effective solutions for retail business actors to increase sales and reduce losses. By using this system, retail sellers can make informed decisions about their products, enabling them to optimize their profits and reduce their risks. In conclusion, the increase in the number of industrial products has created challenges for retail merchants, but this research proposes a solution in the form of a group decision support system. Combining Fuzzy Logic, EDAS, and Borda methods results in an effective decision-making process that allows retail sellers to make informed decisions and achieve their business goals.

Abstract

Kebutuhan pengujian aerodinamika menuntut kualitas aliran yang seragam pada terowongan angin subsonik. Penelitian ini bertujuan mengoptimasi konfigurasi screen mesh dan honeycomb untuk menurunkan intensitas turbulensi dan menghasilkan aliran laminar pada subsonic wind tunnel skala laboratorium. Metode yang digunakan adalah eksperimen dengan tujuh konfigurasi, mulai tanpa screen, satu hingga tiga lapis screen mesh, serta kombinasi screen mesh dan honeycomb. Visualisasi aliran dilakukan menggunakan smoke visualization pada test section. Hasil menunjukkan bahwa empat konfigurasi awal masih menampilkan pola aliran berpusar dengan kecepatan sekitar 5,8–5,4 m/s. Penambahan honeycomb pada konfigurasi kelima hingga ketujuh menghasilkan aliran yang lurus dan stabil dengan kecepatan lebih rendah (±4,6–4,3 m/s) dan karakteristik laminar flow. Konfigurasi tiga lapis screen mesh dan honeycomb memberikan kestabilan aliran terbaik dan direkomendasikan untuk pengujian aerodinamika bodi kendaraan. Reliable aerodynamic testing requires highly uniform flow in a subsonic wind tunnel. This study aims to optimise the configuration of screen mesh and honeycomb inserts to reduce turbulence intensity and obtain laminar flow in a laboratory-scale subsonic wind tunnel. An experimental method was employed with seven configurations: no screen, one to three layers of screen mesh, and combinations of screen mesh and honeycomb. Airflow in the test section was evaluated using smoke visualization. The first four configurations still exhibited vortical patterns with velocities around 5.8–5.4 m/s. Adding a honeycomb in the fifth to seventh configurations produced straight and stable streamlines with lower velocities (≈4.6–4.3 m/s) characteristic of laminar flow. The configuration with three layers of screen mesh and a honeycomb yielded the most stable flow and is recommended for aerodynamic testing of vehicle bodies.
