Kamita Cookies merupakan industri kecil dan menengah (IKM) di Bogor yang memproduksi kue kering. Setiap tahun, IKM mengalami permintaan kue kering yang tinggi menjelang hari raya. Meski sudah beroperasi sejak tahun 2015, namun IKM menghadapi kendala terkait ketahanan kue kering, yang dikhawatirkan tidak bisa terjual maksimal di luar sistem pra-pesan. Melalui kegiatan Pengabdian Kepada Masyarakat (PKM), dosen Politeknik AKA Bogor merancang solusi untuk pemantauan suhu dan kelembaban cookies menggunakan peralatan sistem akuisisi data secara real time berbasis mikrokontroler yang terhubung ke internet (IoT). Rangkaian kegiatan PKM meliputi tahapan survei, penerapan peralatan, dan pelatihan ke IKM. Hasil dari kegiatan ini diharapkan dapat memberikan informasi yang akurat kepada Kamita Cookies mengenai ketahanan produk kue keringnya, sehingga dapat menjadi landasan untuk meningkatkan produksi dan memperluas pasar. Dengan informasi tersebut, Kamita Cookies dapat memanfaatkan peluang distribusi produk ke toko kue, toko oleh-oleh, dan pasar ritel lainnya, sekaligus meningkatkan daya saing dan keberlanjutan usahanya.

Indonesia is a tropical country rich in biodiversity, including a wide variety of herbal plants. Herbs and spices are abundant in Indonesia and have been used in local customs since ancient times. Turmeric, ginger, and curcuma are rhizomes used as spices in Indonesian cooking and natural medicine. This study investigates the efficiency of natural deep eutectic solvents (NADES) synthesized from choline chloride and various sugars—fructose, glucose, maltose, and xylose in extracting polyphenolic compounds from Indonesian rhizomes: turmeric (Curcuma longa), red ginger (Zingiber officinale), and aromatic ginger (Kaempferia galanga L). The NADES were prepared using choline chloride as hydrogen bond acceptor (HBA). The hydrogen bond donor (HBD) is a sugar such as fructose, xylose, maltose, and glucose. The total phenolic content (TPC) was quantified and reported in mg gallic acid equivalent (GAE)/g extract. Kaempferia galanga exhibited the highest TPC among the rhizomes, reaching 32.21 mg GAE/g when extracted with ChCl–Fructose NADES. Curcuma longa and Zingiber officinale yield 20.05 mg GAE/g and 25.84 mg GAE/g under the same solvent conditions, respectively. When comparing the performance of the solvents, the following order was observed: ChCl–Fr > ChCl–Xyl > ChCl–Mal > ChCl–Glu. These findings suggest that solvent polarity and hydrogen bonding capacity significantly influence polyphenol solubility and extraction efficiency. NADES based on ChCl–Fructose showed the greatest potential for eco-friendly extraction of bioactive phenolics from medicinal rhizomes.

Natural deep eutectic solvents (NADES) have become popular as an environmentally benign alternative to conventional solvents for extracting natural compounds. In this current research, choline chloride was employed as a hydrogen bond acceptor (HBA) and was mixed with fructose which had the role of a hydrogen bond donor (HBD) to construct NADES. This extracting agent was deployed to separate the polyphenolic compounds from the stem of Jotang (Spilanthes acmella) under prime conditions. The extracted polyphenol was subsequently calculated based on the Folin-Ciocalteu method using gallic acid as the standard solution by UV-Vis spectrophotometer at 760 nm. Corresponding to the research outcomes, the most gainful states of extraction were achieved at a sample weight-to-NADES volume ratio of 1:50, a period of extracting process of 60 min, water content of 20%, and a stirring speed of 80 rpm. The optimized parameters were conceived as the most gainful because they exhibited the most prominent level of polyphenol were described as follows: ratio of sample weight-to-NADES volume and extraction time showed polyphenol content of 25.13 mg GAE/g each, while the others, stirring speed and water content revealed the polyphenol concentration of 25.75 mg GAE/g respectively.
