Abstract

The peel of red dragon fruit usually discarded. It is rich in polyphenol compounds that have antioxidant activity and health benefits. This research aimed to determine the antioxidant properties of herbal tea such as phenolic content, betacyanin content, and antioxidant activity. The herbal tea prepared with hot oven drying methods, where’s the fresh peel of red dragon fruit and ginger were cut to be small pieces and dried at 60oC, and ground into tea powder then mixed as treatments. Results showed that the addition of ginger has no significant effect on phenolic content, and betacyanin content decreased by the addition of ginger. The phenolic content of herbal tea (0% ginger) and the highest addition of ginger (12%) were 3.39±1.19 mg GAE/g and 3.59±1.43 mg GAE/g respectively. The betacyanin content were 124.63±1.61 mg/100 g (0% ginger) and 104.01±2.99 mg/100g (12% ginger). As the amount of ginger added increased, the percentage of inhibition of herbal tea decreased from 66.23%±2.67 to 61.19%±2.45%.

Abstract

Plastic is a commonly used packaging material due to its cheap and wide availability, especially in the food industry. However, plastic is non-biodegradable, leading to a serious problem to the environment from its widespread use. Using starch-based edible films as an alternative to plastic packaging offers a solution to this problem. As opposed to conventional methods of starch extraction for edibles, modern methods such as microwave-assisted extraction (MAE) can improve the functional properties of starchThis research aimed to determine the physicochemical properties of edible films from starch extracted through MAE. The study used a completely randomized design (CRD) with three treatments based on the amount of added starch, namely, Treatment A (3%), Treatment B (4%), and Treatment C (5%). The results from these treatments were compared against control (without MAE). Observations were conducted in triplicate, including parameters such as solubility, thickness, water holding capacity (WHC), oil holding capacity (OHC), and water content. Treatment A (3%) was found to be the best treatment, with a solubility of 76.55%, a thickness of 0.243 mm, a WHC of 38.56%, an OHC of 36.67%, and a water content of 13.79%.

Abstract

Salah satu sumber utama pendapatan masyarakat Koto Tangah Simalanggang, Kecamatan Payakumbuh adalah beternak ayam pedaging. Nilai jual yang fluktuatif dari distributor menyebabkan ketidakstabilan pendapatan masyarakat. Hilirisasi daging ayam menjadi produk olahan pangan sehat dan bergizi merupakan salah satu langkah yang dapat dilakukan masyarakat untuk meningkatkan pendapatan melalui usaha kuliner yang dapat menyerap tenaga kerja. Pelatihan teknologi pengolahan produk pangan berbahan baku daging ayam bagi Kelompok Wanita Tani (KWT) Koto Tangah Simalanggang bertujuan untuk meningkatkan keterampilan dan melahirkan jiwa wirausaha di bidang kuliner produk olahan daging ayam. Metode pelatihan dilakukan melalui 3 tahapan yaitu persiapan kegiatan, diskusi dan demonstrasi, evaluasi dan pembimbingan yang berlangsung selama 10 pertemuan. Kegiatan pelatihan dilakukan di Kantor Wali Nagari Koto Tangah Simalanggang. Berdasarkan kegiatan pelatihan yang telah dilaksanakan, dapat disimpulkan bahwa KWT Koto Tangah Simalanggang telah memiliki keterampilan hilirisasi produk pangan berbasis daging ayam dan mampu menerapkan teknologi pengolahan pangan dalam pengolahan abon, bakso dan nugget ayam. KWT juga telah memiliki rencana membuka usaha kuliner di bidang produk olahan ayam pedaging guna meningkatkan pendapatan dan menyerap tenaga kerja.
