Abstract

Pencemaran logam berat merupakan permasalahan lingkungan yang cukup banyak menimbulkan dampak negatif bagi kehidupan. Salah satu sumber terbesar pencemaran logam berat adalah kegiatan industri. Logam berat yang dihasilkan dari kegiatan industri dapat mencemari air, tanah dan juga udara. Seiring dengan berjalannya waktu, maka akan semakin tinggi akumulasi logam berat yang mencemari lingkungan sehingga akan semakin membahayakan bagi makhluk hidup utamanya manusia. Fitoremediasi merupakan salah satu solusi untuk mengatasi pencemaran logam berat di tanah dan perairan. Fitoremediasi adalah upaya membersihkan zat pencemar dari tanah dan perairan dengan memanfaatkan tanaman. Tanaman yang digunakan untuk fitoremediasi disebut dengan tanaman hiperakumulator. Terdapat banyak jenis tanaman yang dapat dimanfaatkan sebagai tanaman hiperakumulator, salah satunya adalah Alfalfa (Medicago sativa). Tujuan penulisan paper ini adalah untuk mengetahui potensi Alfalfa sebagai tanaman hiperakumulator pada fitoremediasi tanah tercemar logam berat. Metode yang digunakan dalam penulisan paper ini adalah literature review data sekunder yang berasal dari jurnal, buku, dan internet.

Abstract

Price and promotion are important factors that determine purchase intention, but their relationship with perceived risk has not been widely explored, especially in the context of the construction industry. This study aims to find the impact of price and promotion on the purchase intention in construction services, with the perceived financial risk as the mediation variable. A quantitative approach was used in this study, where the data were collected through a constructed questionnaire. The questionnaire was designed to simultaneously filter respondents, leaving only 144 responses selected for further analysis, namely from those who were planning to renovate their homes, were interested in using construction services, and lived in the Magelang area and its surroundings. The analysis utilized SmartPLS4 for Partial Least Squares Structural Equation Modeling (PLS-SEM). The analysis showed that the price and promotion influence the purchase intention, as well as the promotion affecting the perceived financial risk. The mediation results show that perceived financial risk does not have a significant influence on purchase intention as a mediating variable between price and purchase intention, as well as between promotion and purchase intention. These findings provide insight into how price and promotions shape purchase intentions without considering potential financial losses. This research contributes to construction businesses' efforts to improve purchase intentions, which can aid in new project acquisitions.

Abstract

The increasing demand for home renovation service, coupled with the growing number of households in Indonesia, has also increased competition in this sector. Businesses whose revenue depends on new projects require the right marketing strategy to increase customer acquisition, and purchase intention is a crucial step in this process. This study aims to determine 7P marketing mix elements effect on purchase intention in a renovation service company. A quantitative approach was used in this study, involving 144 collected samples who had home renovation plans and lived in Magelang, Yogyakarta, Solo, and the surrounding areas. The data collected were analyzed using SmartPLS4. The results showed that price and promotion significantly influenced purchase intention using home renovation services. Price had the highest impact in influencing purchase intention. While, product, place, people, process, and physical evidence did not significantly influence purchase intention. This study contributes to marketing theory by extending the 7Ps framework to the small-scale construction context, where service tangibility and project-based transactions dominate decision-making. The findings highlight that in the home renovation industry, price and promotion drive purchase intention more strongly than people or process, suggesting the need to adapt traditional marketing mix models for project-based services.
