Abstract

This research explores the use of chatbots in e-commerce from a customer perspective, with the aim of determining how responsiveness affects usability, as well as how this usability affects customer satisfaction. The data collection method used was a questionnaire distributed to 195 respondents. For model and hypothesis testing, SPSS and AMOS software were used. The results of the validity and reliability tests show that the respondent data is valid and reliable for use in hypothesis testing. The normality test shows that the questionnaire data is normally distributed. The multicollinearity test shows that multicollinearity has occurred. The results of the fit model test are that most of the criteria can be met or are fit, so the statistical interpretation results can not only be used on the sample but on the population as a whole. And the hypothesis test shows that there is a significant positive relationship between responsiveness (X) and usability (Y) of the chatbot. These findings indicate that the more responsive a chatbot is, the higher its level of usefulness in the eyes of customers. When a chatbot is able to provide relevant answers, customers tend to feel that the chatbot is effective and practical to use in meeting customer needs. Furthermore, this research also found that usability (Y) significantly influences customer satisfaction (Z). In other words, easy-to-use and effective chatbots can increase customer satisfaction in an e-commerce context. When a chatbot is designed with a simple interface, customers can easily ask questions and receive the answers or help they need. In addition, if the chatbot is able to provide accurate and relevant answers, customers feel that their needs can be met.

Abstract

Jamu merupakan sebuah minuman herbal yang mengandung khasiat – khasiat untuk menyembuhkan berbagai penyakit salah satunya untuk penyakit asam urat. Kebanyakan masyarakat masih belum memahami tentang jamu dan dalam memilih produk jamu untuk mengobati penyakit asam urat. UD HF BERSAUDARA yang berlokasi di Kabupaten Trenggalek - Jawa Timur. Di lokasi ini terdapat sebuah tempat usaha yang bergerak di bidang pembuatan berbagai jamu salah satunya adalah jamu untuk penyakit asam urat, dengan perkembangan teknologi dan informasi yang semakin maju dan luas hal ini dapat dimanfaatkan oleh produsen untuk menjual dan memberikan sebuah informasi terhadap calon pembeli yang masih binggung dalam menentukan produk jamu asam urat sesuai dengan kebutuhannya, Maka dari itu peneliti ingin memberikan sebuah rekomendasi untuk pemilihan produk jamu bagi pengidap asam urat dengan menggunakan metode SAW (Simple Additive Weighting). Metode ini dipilih karena dapat menentukan nilai bobot untuk setiap atributnya, dengan mengimplementasikan sebuah perhitungan sesuai dengan rumus dari metode ini menggunakan microsoft excel yang di harapakan mampu memberikan sebuah hasil yang valid untuk setiap alterantifnya, dari proses perhitungan tersebut mendapakan sebuah hasil Produk Jamu Marem yang keluar menjadi alternative terbaik dengan nilai 0,758.

Abstract

This study aims to analyze the effect of pulley diameter variation on the performance of a three-bladed Savonius-type vertical axis wind turbine. Three pulley diameter variations were used, namely 3 inch, 5 inch, and 8 inch, with testing conducted at wind speeds ranging from 3 to 4.5 m/s. The performance parameters measured included rotational speed (RPM), current, voltage, electrical power output, and torque. The results indicate that the 3-inch pulley configuration provides the best overall performance, producing an average power output of 31.01 W, a rotational speed of 145.53 RPM, and a torque of 12.60 Nm. The 5-inch pulley generated an average power output of 29.14 W with a torque of 10.25 Nm, while the 8-inch pulley produced the lowest average power output of 21.56 W and a torque of 9.4 Nm. The decline in performance observed with larger pulley diameters is attributed to increased rotational load and higher wind speed requirements. Therefore, smaller pulley diameters are more suitable for low wind speed conditions, as they enable more efficient power generation. This study provides a useful reference for the development of small-scale wind turbine designs for renewable energy applications.
