Abstract

AbstractOn a typical multi-storey thick building, the use of natural lighting is often limited to penetration through window opening on buildings facade. One of the methods developed to maximize penetration of natural light into multi-storey thick building is implementing light transport system by means of horizontal light pipe into building.  By utilizing a light collector, such system directs sunlight down to specific rooms.            This research compares the efficiency of two passive light-redirecting collector models. The first model is made from a mirror panel, while the second one is made from a transparent acrylic panel. Both models were laboratory tested in a one-to-one scale horizontal light pipe model. The light source of this light pipe model is a spotlight. The two light collector models then observed to determine which one of the two is more efficient.   Based on the observation, it can be concluded that a light collector model made from a mirror panel has four times higher illumination level efficiency compares to a light collector model made from a transparent acrylic panel.  Key Words: light collector, mirror panel, transparent acrylic panel, horizontal light pipe AbstrakSecara umum, penggunaan pencahayaan alami pada bangunan tebal bertingkat banyak terbatas pada penetrasi cahaya melalui bukaan jendela pada fasad bangunan.  Salah satu metode untuk memaksimalkan penetrasi pencahayaan alami ke dalam bangunan tebal bertingkat banyak adalah dengan menerapkan sistem penyalur cahaya berupa pipa cahaya horisontal ke dalam sebuah bangunan. Dengan menggunakan kolektor cahaya, sistem tersebut menghantarkan sinar matahari langsung ke ruangan yang memerlukan.   Studi ini membandingkan tingkat efisiensi dari dua rancangan model kolektor cahaya pasif. Model pertama terbuat dari panel cermin dan model kedua terbuat dari panel akrilik transparan. Kedua model kolektor cahaya ini diuji di laboratorium dengan menggunakan sebuah model pipa cahaya horisontal berskala satu banding satu. Sumber cahaya pada model pipa cahaya horisontal ini adalah sebuah lampu sorot. Kedua model kolektor cahaya kemudian diamati dan dibandingkan efisiensinya.Sebagai kesimpulan dari studi ini, model kolektor cahaya dari panel cermin memiliki efisiensi tingkat pencahayaan empat kali lebih besar dibandingkan dari model kolektor cahaya yang terbuat dari panel akrilik transparan. Kata Kunci: kolektor cahaya, panel cermin, panel akrilik transparan, pipa cahaya horisontal

Abstract

The Argomulyo Culinary Center (ACC), a growing culinary hub in Yogyakarta, aims to attract local tourists but lacks a structured marketing approach to increase visitor purchase intention. To establish a foundation for designing a marketing approach, this study examines the influence of the 4P Marketing Mix (Product, Price, Place, and Promotion) on Purchase Intention at ACC. A quantitative approach was used, employing Multiple Linear Regression with Purposive Sampling of 160 Yogyakarta-based visitors. Data were collected through structured surveys and analyzed using SPSS software. The results indicate that Product has a significant effect on Purchase Intention (β = 0.226, p = 0.013), while Price (p = 0.983), Place (p = 0.508), and Promotion (p = 0.227) do not have significant partial effects. However, all four variables simultaneously influence Purchase Intention (p < 0.001). These findings suggest that ACC should prioritize product development, including expanding menu variety, enhancing quality of ingredients, and improving food presentation. Additionally, a training program for tenants is recommended, focusing on culinary innovation, digital marketing, and customer experience enhancement. These efforts are expected to strengthen ACC’s competitive position and attract more visitors. This research offers valuable insights for culinary businesses, especially in developing economies, struggling to establish a strong market presence.  It demonstrates the critical role of product quality and innovation in driving purchase intention, highlighting the need for a holistic marketing approach and targeted training programs to enhance competitiveness.
