Abstract

Kratom is one of the export commodities from West Kalimantan, containing alkaloids that are beneficial to health. The export product currently in demand is extracted flour. So far, the most widely used extraction method is conventional single extraction, using maceration which is inefficient, long and consumes a lot of solvents. This study examined the process of alkaloid extraction using the technology of drying with a microwave and extraction using a sonicator. The study aimed to determine the microwave drying method which produces kratom leaf alkaloid levels and the type of solvent which produces the strongest IC-50 antioxidant properties from the bath-type sonicator multilevel extraction method. The research method was divided into 2 stages, namely, stage 1 drying with 2 ingredients, kratom leaves with veins and without veins, then tested for alkaloid levels. The leaves material with high alkaloids was continued for phase II of the IC-50 antioxidant property test from various solvents (hexane, methanol, ethanol) using multilevel extraction with a bath-type sonicator. Data analysis was carried out descriptively. The results showed that leaves without veins produced relatively higher levels of alkaloids than leaves with veins. The type of burner that produced IC-50 antioxidant activity was 0.3 ppm ethanol extract. Thus, these results can be a recommendation to stakeholders

Abstract

Kemasan merupakan salah satu faktor penting yang memengaruhi nilai tambah dan daya saing produk pangan. Penelitian ini bertujuan untuk merancang desain kemasan produk bubuk kakao dan minuman cokelat siap minum Cokelat Desa Kakao Kulon Progo (Progo Choco) dengan menggunakan pendekatan value engineering. Penelitian dilakukan di Yogyakarta dan Kulonprogo dengan melibatkan preferensi konsumen sebagai data primer yang diperoleh melalui observasi, wawancara, dan penyebaran kuesioner. Metode value engineering diterapkan melalui empat tahapan, yaitu tahap informasi, kreativitas, analisis, dan pengembangan. Atribut mutu kemasan yang dianalisis meliputi bentuk, bahan, kemudahan, warna, label, dan biaya. Hasil penelitian menunjukkan bahwa konsumen mengutamakan kemasan yang praktis, informatif, menarik secara visual, serta memiliki biaya produksi yang efisien. Evaluasi terhadap tiga konsep kemasan, yaitu sachet aluminium foil, kotak (box) kertas Ivory, dan botol plastik PET, menunjukkan bahwa konsep kemasan kotak memiliki nilai (value) tertinggi berdasarkan perbandingan performansi dan biaya. Dengan demikian, kemasan kotak direkomendasikan sebagai desain kemasan terbaik untuk produk Cokelat Desa Kakao Kulon Progo. Penelitian ini diharapkan dapat menjadi referensi bagi UMKM dalam mengembangkan desain kemasan secara sistematis untuk meningkatkan nilai tambah dan daya saing produk di pasar.
