Abstract

Studi ini berupaya untuk menguji bagaimana diversifikasi produk, kualitas produk, harga, dan kepuasan konsumen memengaruhi keputusan pembelian di Warung Kopi Wans di Rantauprapat. Dengan menggunakan pendekatan kuantitatif, kami melakukan survei yang melibatkan 96 responden, menganalisis data melalui regresi linier berganda. Temuan tersebut mengungkapkan bahwa semua variabel independent diversifikasi produk, kualitas produk, harga, dan kepuasan konsumen berdampak positif dan signifikan terhadap keputusan pembelian, baik secara individu maupun kolektif. Khususnya, kepuasan konsumen muncul sebagai faktor yang paling berpengaruh. Koefisien determinasi (R²) ditemukan sebesar 62,7%, yang menunjukkan bahwa model kami secara efektif memperhitungkan sebagian besar variasi dalam keputusan pembelian. Hasil ini menyoroti peran penting inovasi produk, kualitas yang konsisten, harga yang didorong oleh nilai, dan layanan pelanggan yang ditingkatkan dalam menumbuhkan loyalitas dan mempromosikan pembelian berulang dalam industri kedai kopi.

Abstract

The numerous rivers and high rainfall in West Sumatra often lead to flooding, which affects several land uses such as settlements, plantations, and agriculture. During floods, water transports various materials from upstream to downstream, such as sand, mud, and clay, which are deposited in certain riverbanks. This study aimed to examine the soil fertility characteristics in the floodplain area. The method used in this research was a survey method with purposive random sampling at two soil depths: 0 – 30 cm and 30 – 60 cm. Samples were taken from two land uses: dryland agriculture and wetland agriculture. The parameters analyzed were texture, organic carbon, bulk density, total pore space, pH in H2O, available P, total N, and exchangeable potassium. The results of the study for each parameter showed that the soil texture in dryland agriculture was sandy loam, while in wetland agriculture, it was clay loam. Organic carbon was classified as low (1.31%–1.62%). Wetland soils had higher porosity (57.67%–61.40%) and lower bulk density (1.01–1.10 g/cm³) compared to dryland soils. Soil pH was acidic (4.52–4.95). Available P, total N, and exchangeable potassium were higher in wetland soils than in dryland soils. In conclusion, the results of the study indicate that the soil properties, both physical and chemical, in wetland agriculture were better than in dryland agriculture, although no significant differences were found.
