The community service activity involves Faculty of Agriculture UNISKA in collaboration with the Pineapple Farmer Group and PT. PNM Kediri Branch. The purpose of the activity was identifying problems with pineapple farmers through survey activities, solving problems through training activities. Pineapple processing in Kediri district was not yet fully implemented. Still maintaining sales in fresh form so it was necessary to add value to the product. The training was held in September 2019. The tools and materials used were a set of cooking utensils and pineapple fruit. The expected output of activities was in the form of a cluster map of pineapple plant farmers in Kediri district and product diversification from pineapple plants.

Abstract

Bunga telang (Clitoria ternatea L.) identik dengan warna biru keunguan dan menghasilkan biji polong berwarna hijau. Tanaman ini tumbuh merambat dan sering dijumpai di pekarangan atau kebun. Sebagian masyarakat belum mengetahui potensi dan manfaat bunga telang. Warna pada bunga telang mengandung antosianin merah hingga ungu pekat. Pigmen antosianin mayoritas tersebar pada bagian bunga, buah dan daun. Kandungan tersebut dapat digunakan sebagai pewarna alami untuk beberapa macam produk olahan makanan atau minuman. Kegiatan ini bertujuan untuk memberi edukasi potensi bunga telang sebagai pewarna alami kepada masyarakat khususnya anggota Pemberdayaan Kesejahteraan Keluarga (PKK) Kelurahan Tempurejo Kecamatan Pesantren Kota Kediri. Kegiatan pengabdian dilaksanakan dengan metode ceramah, tanya jawab dan diskusi secara interaktif. Para peserta sangat antusias dengan tema bunga telang. Sebelum penyampaian materi peserta mengisi pre-test. Setelah sesi tanya jawab dan diskusi, peserta juga dibagikan kuisioner post-test untuk mengukur pemahaman peserta mengenai materi yang telah disampaikan. Hasil evaluasi menunjukkan adanya peningkatan wawasan peserta sebesar 69,3 persen pada pre-test menjadi 94,3 persen pada post-test. Kegiatan pengabdian ditutup dengan pemberian bibit bunga telang kepada peserta untuk ditanam di lahan pekarangan rumah dan produk Teh celup herbal telang serta pewarna alami bunga telang.

Abstract

Rosella (Hibiscus sabdariffa L.) is known as a plant whose calyx contain high levels of antioxidant bioactive compounds and good inhibitory power against free radicals. However, other parts of the rosella plant have not yet been utilized for their antioxidant content and activity. The aim of this research is to compare the profiles of essential oils of parts of the rosella plant (seeds, leaves and flower petals) and their antioxidant activity. This research method begins with the process of extracting essential oils using the water-steam distillation method. Furthermore, the profile of the essential oil is known from the results of yield calculations and characterization using the GC-MS instrument. The antioxidant activity was tested using the DPPH method. The yield of essential oils obtained was 0.0107% for seeds, 0.0087% for leaves and 0.0136% for flower petals. GC-MS characterization shows that the most abundant chemical components contained in the essential oils of seeds, leaves, and flower petals are fatty acid compounds (2-propanoic acid, butanoic acid, hexanoic acid) and esters (neopentyl isobutyrate). The results of the antioxidant activity test showed the IC50 value for each essential oil, namely, seeds: 30.15 μg/ml, leaves: 171.27 μg/ml and flower petals: 126.58 μg/ml. The compound characteristics obtained showed the best results for rosella seed essential oil, this was supported by the fairly high antioxidant activity test results IC50 <50 μg/ml. Keywords: Antioxidant activity, Characterization, Essential oils, IC50, Yield.
