Abstract

Lupinus angustifolius is legume that has high protein. Most of this plant growth in Australia. Another name of L. angustifolius is Australian sweet lupin. L. angustifolius is potentially use as the source of food. Tofu is one of the traditional foods in Indonesia.Tofu is madefrom the coagulation of soybean protein. L. angustifolius has globulin protein that has a role in the production of tofu. The price of L. angustifolius is cheaper than soybean. In this research, L. angustifolius has beenused as the substitution in the tofu production. Thepurpose of this researchis toknow the nutrition and potential of L. angustifolius as the substitute in tofu. This research is also monitoring the effect of coagulant agent that is used in tofu. The research result shows that the optimum concentration substitution of lupin that is used in tofu is 30% with CaCl2 coagulant agent. The tofu that is made from 30% lupin with CaCl2 contained 17.22% protein, 5.23 fat, and 1.14% carbohydrate. The observation shows that tofu that is made from 30% substitution of L. angustifolius has higher protein than tofu which is without substitution of L. angustifolius.Keywords: Lupinus angustifolius, coagulant agent, tofu, protein.

Abstract

In the healthcare sector, patient revisit intention serves as an important measure of hospital success, influencing financial stability, operational effectiveness, and long-term patient retention. With increasing competition, hospitals must strengthen trust, improve service quality, and maintain a positive institutional image to retain patients. This study focuses on the declining number of non-BPJS (non-insured) patients at Cinta Kasih Tzu Chi Hospital, Cengkareng, which impacts revenue sustainability. The research aims to assess how trust and customer perceived value affect revisit intention, and whether hospital image moderates these relationships. A quantitative approach was applied using a structured questionnaire distributed to 95 non-BPJS outpatients who had previously sought treatment more than once. Data were analyzed through Structural Equation Modeling (SEM) using the Partial Least Squares (PLS) method via SmartPLS software. The findings reveal that both trust and perceived value significantly and positively influence revisit intention, implying that patients with strong trust and satisfaction tend to return. Although hospital image directly influences revisit intention, it does not significantly moderate the link between perceived value and revisit intention. Therefore, hospitals are advised to enhance patient trust and perceived value while sustaining a credible institutional image to strengthen loyalty among non-BPJS patients
