The Indonesian traditional moist cake industry including putu cake, lapis cake, and apem cake, still relies heavily on synthetic food colorings that pose health risks. Natural colorings are a safer alternative, as they are often derived from plants or food waste, such as suji leaves, beets, and dragon fruit peel. Red dragon fruit peel (Hylocereus polyrhizus) has potential as a natural dye alternative because it contains high levels of betacyanin, which acts as an antioxidant while also providing a rich color. Steamed apem cake is one of Indonesia's traditional cakes that has cultural value and is widely consumed by the community. Color is one of the factors influencing product attractiveness; however, synthetic food colorants are still commonly used and may pose health risks if used improperly. Natural colorants are a safer alternative and can be obtained from various plants, such as carrots, pandan leaves, and dragon fruit. Red dragon fruit peel, a by-product of the fruit processing industry, contains betalain pigments and has the potential to be utilized as a natural food colorant. This study employed an experimental method using a Completely Randomized Design (CRD) with four treatments: 0%, 35%, 50%, and 65% substitution of dragon fruit peel extract. Product quality was evaluated through ranking and hedonic tests using a 7-point scale by 30 semi-trained panelists. Data were analyzed using Analysis of Variance (ANOVA), followed by Duncan's Multiple Range Test (DMRT) at a 5% significance level when significant differences were detected. The results showed that dragon fruit peel extract substitution significantly affected color quality (F = 69.64 > Ftable = 2.71) and texture (F = 23.60 > Ftable = 2.71), but had no significant effect on shape (F = 0.05 < Ftable = 2.71), aroma (F = 0.82 < Ftable = 2.71), or taste (F = 0.48 < Ftable = 2.71). In the hedonic test, the substitution significantly affected panelists' preference for color (F = 23.91 > Ftable = 2.71) and taste (F = 13.91 > Ftable = 2.71), while no significant effects were observed for shape, aroma, and texture. The best treatment was obtained with 65% dragon fruit peel extract substitution, indicating its potential as a natural food colorant while improving the sensory quality of steamed apem cake.

Indonesia's traditional wet cake industry, such as glutinous rice cakes, layer cakes, and putu cakes, still use many synthetic dyes that are risky to health. Natural dyes are a safer alternative, because many are obtained from plants or food waste, such as pandan leaves, sugi leaves, and dragon fruit peels. The skin of the red dragon fruit (Hylocereus polyrhizus) has the potential to be an alternative to natural dyes because it contains high betacyanin which is antioxidant while providing an attractive purplish red color. This study aims to analyze the comparison of the sensory quality of pandan sticky rice talam cake (control) with glutinous rice talam cake with 50 ml of red dragon fruit peel extract. The research method used was a quantitative experiment with a comparative test approach (Independent Samples t-test), involving a rating test and a hedonic test conducted by 30 panelists, and analyzed by comparing the values of |tcalcul| against the table at a significance level of 5% (ttable = 2.00172). The results showed that the addition of dragon fruit peel extract had a significant effect on the quality of color (count 42.115 > table 2.00172) and aroma (count 8.494 > table 2.00172) organolepically, as well as on the level of color, texture, and taste preference (counts 5.220; 2.383; and 2.208 > table 2.00172), but did not have a significant effect on the organoleptic quality of shape, texture, and taste or the level of shape preference. The overall best treatment was sticky rice talam cake with dragon fruit peel extract (X1), although the panelists preferred the aroma of pandan sticky rice cake without extract (X0). This study proves that red dragon fruit peel extract can be used as a natural dye while improving the sensory quality of glutinous rice talam cake. Further research is recommended to examine the shelf life, antioxidant content, and nutritional value of the product.

This study develops an integrative model of employee productivity by examining the roles of digital capability, leadership, and operational excellence in the context of digital transformation within Indonesia’s food and beverage manufacturing industry. Although previous studies have investigated these constructs separately, limited research has integrated them into a comprehensive structural framework. A quantitative explanatory design was employed using survey data collected from 200 employees of PT Ultrajaya Milk Industry & Trading Company Tbk. The proposed relationships were analyzed using Structural Equation Modeling (SEM). The findings reveal that digital capability is the strongest determinant of employee productivity, followed by leadership, while operational excellence significantly enhances productivity and partially mediates the effects of both digital capability and leadership. The results indicate that organizations can achieve sustainable productivity by simultaneously strengthening employees’ digital competencies, developing transformational leadership, and fostering operational excellence. The study contributes to the Resource-Based View and Human Capital Theory by demonstrating that technological capability, leadership quality, and organizational processes function as complementary strategic resources for improving workforce productivity. Practically, the findings provide managerial guidance for designing integrated digital transformation and human capital development strategies to enhance organizational competitiveness.

Penelitian ini dilatar belakangi oleh meningkatnya kebutuhan pakan ternak berkualitas sepanjang tahun serta pentingnya pengelolaan rantai pasok yang efisien pada usaha mikro, kecil, dan menengah (UMKM) silase. Permasalahan utama dalam penelitian ini adalah bagaimana proses produksi dan distribusi silase serta bagaimana penerapan model Supply Chain Operations Reference (SCOR) dapat mengidentifikasi hambatan pada rantai pasok sehingga dapat meningkatkan efisiensi produksi dan distribusi. Tujuan penelitian ini adalah untuk mengetahui proses produksi dan distribusi silase skala UMKM di Desa Trikarya, Kecamatan Belitang III, Kabupaten OKU Timur serta menganalisis penerapan model SCOR dalam mengidentifikasi hambatan pada rantai pasok silase. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif dengan pendekatan studi kasus terhadap lima pelaku UMKM silase yang dijadikan responden. Data primer dikumpulkan melalui observasi, wawancara, dan pencatatan, kemudian dianalisis menggunakan analisis biaya, penerimaan, pendapatan, serta pendekatan model SCOR yang meliputi proses Plan, Source, Make, Deliver, dan Return. Hasil penelitian menunjukkan bahwa proses produksi silase meliputi persiapan bahan baku, pencacahan hijauan, pencampuran bahan tambahan, fermentasi selama 14–21 hari, pengemasan, dan distribusi kepada peternak. Rata-rata biaya tetap sebesar Rp484.026 per proses produksi dan biaya variabel sebesar Rp351.200 per proses produksi, sehingga total biaya produksi mencapai Rp835.226 per proses produksi. Dengan rata-rata produksi sebesar 304 kg per proses produksi dan harga jual Rp6.200/kg, diperoleh penerimaan sebesar Rp1.968.000 dan pendapatan sebesar Rp1.132.774 per proses produksi. Berdasarkan analisis SCOR, hambatan utama rantai pasok terdapat pada ketersediaan bahan baku hijauan yang bersifat musiman, keterbatasan kapasitas alat produksi, serta distribusi yang masih terbatas pada wilayah sekitar. Penerapan model SCOR mampu mengidentifikasi titik-titik perbaikan pada setiap aktivitas rantai pasok sehingga berpotensi meningkatkan efisiensi produksi, kelancaran distribusi, dan daya saing UMKM silase.
