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.

Abstract

Penelitian ini bertujuan untuk mengetahui: 1) Tingkat preferensi konsumen pada kemasan jahe merah instan dan 2) Mengetahui deskripsi kemasan yang paling diminati oleh konsumen. Penelitian dilakukan di CV Merapi Farma Herbal dengan metode deskriptif kuantitatif. Pengambilan sampel responden menggunakan accidental sampling dengan melibatkan 40 konsumen. Metode conjoin digunakan untuk menentukan tingkat preferensi konsumen berdasarkan 9 stimuli yang terbentuk menggunakan 4 atribut yaitu jenis kemasan, warna, berat bersih, dan informasi produk. Hasil penelitian menunjukkan bahwa responden menyukai stimuli ke-3 dengan jenis kemasan kotak karton, dengan warna merah, berat bersih 100gram, dan informasi produk yang berisi komposisi, cara konsumsi, berat bersih, expired date, dan informasi produsen. Deskripsi kemasan terpilih berdasarkan nilai kegunaan dan kepentingan konsumen menyukai kemasan dengan jenis kemasan kotak karton, warna hitam-putih, berat bersih 100gram, dan informasi produk yang berisi komposisi, cara konsumsi, berat bersih, expired date dan informasi produsen.

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

Agricultural Machinery Service Unit (Unit Pelayanan Jasa Alsintan, UPJA) Barokah is an agricultural economic institution that provides agricultural machinery and equipment services in Trimulyo Village, Jetis Kapanewon, Bantul Regency. UPJA plays an important role in supporting agricultural mechanization; however, its management still faces various internal and external constraints that affect business development. This study aimed to identify the internal and external factors influencing the performance of UPJA Barokah, formulate business development strategies using SWOT analysis, and determine priority strategies using the Quantitative Strategic Planning Matrix (QSPM) method. The study was conducted from November 2025 to April 2026 using a descriptive qualitative approach. Data were collected through interviews, participatory observation, Focus Group Discussion (FGD), and documentation. Data were analyzed using the IFAS, EFAS, SWOT, and QSPM matrices. The results showed that the total IFAS score was 2.29 and the EFAS score was 2.56, placing the organization in Quadrant III. This condition indicates that UPJA Barokah has considerable development opportunities but still faces internal weaknesses that need to be improved. Based on the SWOT matrix, the prioritized strategy was the Weakness–Opportunity (WO) strategy. The QSPM analysis showed that the main priority strategy was to increase member participation and regenerate operator human resources through role distribution and the introduction of agricultural mechanization to the younger generation, with a Total Attractiveness Score (TAS) of 6.09.
