This study was aimed to evaluate the utilization of hydrolyzed Indigofera zolingeriana by celullase enzyme as the feed ingredient of gourami fish. This study used a completely randomized design which contained three steps, whereas each step contained four treatments and four replications. The first step performed by evaluating the Indigofera leaf meal (ILM) added with cellulase enzyme of 0 g/kg (control), 0.4 g/kg, 0.8 g/kg, and 1.2 g/kg. The second step was the digestibility test of ILM on gourami seeds. The third step was feed evaluation added with ILM as much as 0% (control), 15%, 30%, and 45% against the growth performance on gourami seeds. The gourami seeds used in the second and third steps with a weight of 13.65 ± 0.39 g/seed and 5.95 ± 0.15 g/seed, respectively. The addition of 0.8 g/kg and 1.2 g/kg cellulase enzyme could significantly decrease the crude fiber of ILM with 43.33%, besides having the best value of total, ingredient, protein, lipid, and energy digestibility. The growth performance of gourami seeds given 15% ILM added feed had the best value and insignificantly different from the control feed without ILM addition based on the specific growth rate (SGR), protein retention (PR), and feed efficiency (FE). Keywords: Cellulase, feed, hydrolyze, Indigofera zolingeriana, Osphronemus gouramy. ABSTRAK Penelitian ini dilakukan untuk mengevaluasi pemanfaatan daun Indigofera zolingeriana yang dihidrolisis enzim selulase sebagai bahan baku pada pakan benih ikan gurami. Penelitian ini menggunakan rancangan acak lengkap yang terdiri atas tiga tahap, dimana masing-masing tahap terdiri dari empat perlakuan dan empat ulangan. Pada tahap pertama dilakukan evaluasi tepung daun Indigofera (TDI) yang ditambahkan enzim selulase sebesar 0 g/kg (kontrol), 0.4 g/kg, 0.8 g/kg, dan 1.2 g/kg. Pada tahap kedua dilakukan uji kecernaan bahan TDI pada benih ikan gurami. Pada tahap ketiga dilakukan evaluasi pakan yang ditambahkan TDI sebesar 0% (kontrol), 15%, 30% dan 45% terhadap kinerja pertumbuhan pada benih ikan gurami. Benih ikan gurami yang digunakan pada penilitian tahap kedua dengan bobot 13.65 ± 0.39 g/ekor dan 5.95 ± 0.15 g/ekor. Penambahan enzim selulase pada dosis 0.8 g/kg dan 1.2 g/kg secara signifikan mampu menurunkan serat kasar TDI sebesar 43.33 % dan memberikan nilai terbaik terhadap nilai kecernaan total, kecernaan bahan, kecernaan protein, kecernaan lemak dan kecernaan energi. Kinerja pertumbuhan benih ikan gurami yang diberikan pakan yang ditambahkan TDI sebesar 15% memilki nilai terbaik dan tidak berbeda nyata terhadap pakan kontrol tanpa TDI dari aspek laju pertumbuhan spesifik (LPS), retensi protein (RP) dan efisiensi pakan (EP). Kata kunci: Hidrolisis, Indigofera zolingeriana, Osphronemus gouramy, pakan, selulase.

Introduction: Rheumatoid Arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints, which can lead to cartilage damage and disability. Not all standard medications for RA therapy are efficient for all patients and long-term use can cause serious side effects. Therefore, it is necessary to develop drugs for RA involving various approaches, both pharmacological and non-pharmacological. Method: This article review is based on references to several articles from online databases published nationally and internationally. Result: From the article search, there were 10 articles discussing RA drug development from various approaches. Conclusion: Based on the review of articles carried out, there is drug development using a pharmacological approach including the use of natural ingredients such as purslane tea, red betel leaf extract, secang plants and curcumin, nanotechnology-based innovations such as composite hydrogel and MTX nanocarriers, a drug repurposing approach to the discovery of new drugs alpha-linolenic acid and Belatacept as well as non-pharmacological approaches with complementary therapies such as red ginger and warm betel compresses. Keywords: Drug development, treatment, rheumatoid arthritis

The development of digital banking technology, particularly internet banking, has rapidly advanced in the digitalization era. However, the adoption of this service still faces various challenges, especially those related to user perception. This study aims to analyze the influence of perceived usefulness, perceived ease of use, and perceived risk on the interest of Batam City residents in using internet banking services. This research employs a quantitative method by collecting data through questionnaires distributed to potential internet banking users in Batam City. The obtained data is analyzed using multiple linear regression methods. The results indicate that perceived usefulness and perceived ease of use have a positive and significant effect on the intention to use internet banking, while perceived risk has a negative and significant effect. These findings suggest that increasing awareness of the benefits and ease of use of internet banking can encourage its adoption, while concerns about risks should be minimized by banks to enhance user trust. Keywords: Perceived Usefulness, Perceived Ease of Use, Perceived Risk, Intention to Use Internet Banking.
