Abstract

Raw material inventory management determines the company's impressive steps that affect the company's financial stability. The research aims to determine the efficient amount of ordering raw materials total inventory costs before and after using the Economic Order Quantity (EOQ) method, Re-Order point, and buffer inventory (Safety Stock) on Simplicia spoon, mint, and stevia. The research was carried out from January to June 2023 at PT Lawu Flora Wijaya, Karanganyar Regency. The method used in the research is a quantitative descriptive method. Based on research results using 2022 data, PT Lawu Flora Wijaya has been efficient in ordering 261.05 kg of Simplicia spoon raw materials, 104.74 kg of mint Simplicia, 84.64 kg of stevia Simplicia. The total cost of raw material inventory for Simplicia before using EOQ is Rp. 409,234 for spoon simplicia, Rp. 214,026 for mint simplicia, and Rp. 145,471 for stevia simplicia. Meanwhile, using the EOQ method, Rp. 402,171 was obtained for spoon simplicia, Rp. 189,937 for mint simplicia, and Rp. 144,609 for stevia simplicia. The reorder point for the raw material Simplicia spoon was 142.9 kg, simplicia mint was 15.1 kg, and Simplicia stevia was 25 kg. The buffer stock for spoon simplicia is 126.72 kg, mint simplicia is 11.92 kg, and stevia simplicia is 22.92 kg.

Abstract

This study aimed to evaluate the effect of drying temperature on the chemical and organoleptic properties of formulated kenikir (Cosmos caudatus K.) herbal tea bags. The experiment was arranged using a Completely Randomized Design (CRD) with a single factor, namely drying temperature at 40, 50, 60, 70, and 80°C with three replications, resulting in 15 experimental units. Kenikir leaves were dried prior to formulation with green tea (50%), kenikir leaves (30%), and jasmine (20%). Treatments at 40°C and 50°C were not further analyzed due to moisture content exceeding the standard limit (>8%). The analyses included moisture content, yield, total phenolic content (Folin–Ciocalteu method), total flavonoid content (AlCl₃ method), antioxidant activity (DPPH method), and sensory evaluation (color, aroma, and taste). Data were analyzed using analysis of variance (ANOVA) at a 5% significance level followed by Duncan’s Multiple Range Test (DMRT). The results showed that increasing drying temperature significantly decreased moisture content and yield (p<0.05), while increasing total phenolic and flavonoid contents. The highest antioxidant activity was observed at 60°C with an inhibition value of 33.68%, although it was not significantly different among treatments (p>0.05). Meanwhile, the highest phenolic and flavonoid contents were obtained at 80°C. Sensory evaluation indicated that the 80°C treatment had the highest level of panelist preference. In conclusion, drying temperature significantly affects the chemical and sensory characteristics of formulated herbal tea, with 60–80°C considered the optimal range depending on the evaluated parameters.

Abstract

Penelitian ini merupakan penelitian pengembangan (Research and Develovment) yang digunakan untuk mengetahui valid dan praktis suatu produk. Penelitian ini menggunakan model pengembangan yang dikemukakan oleh Luther dengan 6 tahap yaitu concept, design, material collecting, assembly, testing dan distribution. Teknik pengumpulan data menggunakan lembar wawancara, dan angket serta menggunakan evaluasi formatif yaitu alpha test dan beta test, alpha test terdiri dari validasi ahli materi dan validasi ahli media sedangkan beta test terdiri dari 3 tahapan yaitu One to One, Small group, dan field test. Instrumen lembar One to One untuk mengetahui kekurangan produk berdasarkan penilaian pengguna. Sedangkan validasi ahli, Small group, dan field test berupa angket untuk mengetahui tingkat kevalidan dan kepraktisan produk. Hasil Multimedia Interaktif menunjukkan bahwa dengan penggunaan model pengembangan luther yang di implementasikan pada multimedia interaktif visual studio ini valid dan praktis.
