Abstract

Kentang memiliki potensi untuk memenuhi kebutuhan pangan masyarakat Indonesia. Salah satu kabupaten di Sumatera Utara dengan produksi kentang terbesar kedua adalah Simalungun, sehingga pengembangan harga kentang perlu diawasi dengan baik. Masalah yang dihadapi pada kentang adalah fluktuasi harga, tingginya marjin pemasaran dan transmisi harga disebabkan oleh kekuatan pasar yang dimiliki oleh pedagang pengumpul desa atau pedagang perantara. Tujuan penelitian ini adalah menganalisis transmisi harga kentang di kabupaten Simalungun. Metode penelitian yang digunakan adalah pendekatan model dinamis Error Correction Models (ECM) untuk menganalisis transmisi harga kentang yang terjadi pada jangka pendek dan jangka panjang. Hasil penelitian menunjukkan bahwa Transmisi harga terjadi pada harga di pasar kentang di tingkat produsen ke harga pada pasar konsumen kentang di Kabupaten Simalungun , dimana perubahan harga pada pasar produsen kentang akan ditansmisikan sepenuhnya pada pasar kentang tingkat konsumen di Kabupaten Simalungun dalam jangka panjang, dan membutuhkan waktu 1.5 bulan ditransmisikan dari pasar produsen kentang ke pasar konsumen kentang pada jangka pendek. Kata kunci: harga; kentang ; transmisi

Abstract

This study aims to determine the Effectiveness and Efficiency of the Quick Response Indonesian Standard (Qris) Non-Cash Payment System in Affecting Sales at Coffeeshop in Medan City. This research is a quantitative approach. The population and sample in this study were coffeshops in Medan City that used a non-cash payment system of 127 outlets spread across Medan City. The data analysis technique of this study uses statistical analysis, namely the partial least square-structural equestion model (PLS SEM) which aims to conduct path analysis with latent variables. Variant-based structural equation analysis (SEM) which can simultaneously test the measurement model as well as test the structural model. The results showed that directly the effectiveness of QRIS on coffeeshop sales in Medan city had a significant effect. This result can be seen that the significant value of 0.004 is smaller than 0.05 and the tcount value is greater than the ttable (2.479> 1.979). Directly QRIS efficiency on coffeeshop sales in Medan city has a significant effect. This result can be seen that the significant value of 0.000 is smaller than 0.05 and the tcount value is greater than the ttable (4,452> 1,979). Simultaneously, the effectiveness and efficiency of non-cash payments through QRIS on coffeeshop sales in Medan city have a significant effect.

Abstract

Pakcoy is a type of plant that belongs to the mustard family with the Latin name Brassica rapa L. Pakcoy plants can be cultivated with hydroponic technique, which is a plant cultivation technique without soil media. Hydroponics is one of the solutions in overcoming the limited land in urban areas. This study aims to analyze the effect of nutrient solution concentration and the provision of growth regulators on the growth and production of pakcoy plants using the hydroponic method. The research was conducted in a completely randomized design (CRD) involving two factors. The first factor was the concentration of nutrient solution (N) with two levels: N1 = 700 ppm, 900 ppm, and N2 = 1,000 ppm, 1,200 ppm. The second factor is growth regulator (H) consisting of five levels: H0 = Control (no hormone), H1 = 1 ml/l water, H2 = 2 ml/l water, H3 = 3 ml/l water, and H4 = 4 ml/l water. Parameters observed included plant height, number of leaves, and wet weight. The results showed that the concentration of nutrient solution had a significant effect on the number of leaves and wet weight, but not significant on plant height. Meanwhile, the application of growth regulators also had a significant impact on the number of leaves and wet weight, but had no significant effect on pakcoy plant height. In general, increasing the concentration of nutrient solution and dosage of growth regulators increased the growth of pakcoy plants
