Abstract

Tape ketan hitam merupakan bahan pangan berkhasiat yang mengandung senyawa antosianin. Tujuan dari penelitian ini yaitu untuk mengetahui kadar total antosianin dan aktivitas antioksidan tape ketan hitam dari ekstrak air, metanol dan etanol 70%. Kandungan total antosianin ditentukan menggunakan metode pH differensial pada pH 1,0 dan pH 4,5 dengan hasil rata-rata kadar antosianin total dari ekstrak tape ketan hitam dengan pelarut aquadest sebesar 3,6598 mg/100g, pelarut metanol p.a sebesar 4,1191 mg/100g, dan pelarut etanol 70% sebesar 8,4190 mg/100g. Uji aktivitas antioksidan dilakukan menggunakan metode DPPH dan standar yang digunakannya adalah kuersetin. Hasil penelitian menunjukkan nilai IC50 ekstrak air, metanol p.a, dan etanol 70% secara berturut-turut adalah 119,6697 ppm; 94,6237 ppm; dan 88,4847 ppm. Hasil ini menunjukkan ekstrak tape ketan hitam dengan pelarut etanol 70% menunjukkan kadar total antosianin dan aktivitas antioksidan yang lebih tinggi dibandingkan dengan pelarut metanol p.a dan air.

Abstract

  n the world, hypertension is ranked third as a risk factor for death. In 2025, the increase in cases of hypertension, especially in developing countries, is estimated to be around 80% of the 639 million cases in 2000 or around 1.15 billion cases (Pusparini, 2015). In botany, celery leaves are said to contain Apigenin which can prevent constriction of blood vessels and Phthalides which can relax artery muscles or relax blood vessels. These substances regulate blood flow, allowing blood vessels to dilate and reduce blood pressure. Based on this, it is necessary to empower the community in the use of celery plants to overcome hypertension problems, which is carried out in the Community Service program in the PKM scheme with partners being PKK Cadres RW 09 in Margasari Village, Buah Batu District, Bandung. This PKM activity took place in seven activities, namely: Checking participants' blood pressure before being treated with celery plants, conducting pre-tests on participants before counseling was carried out, weighing celery plants to be distributed to each participant so they could be self-medicating at home, conducting lectures and discussions about hypertension, antihypertensive chemical drugs, and the use of antihypertensive celery plants, demonstrations of making herbal celery drinks which are efficacious as antihypertensives and distributing drinks to participants, carrying out post tests, and checking participants' blood pressure after being treated with celery plants for 3 days . The solution offered is an increase in the knowledge, attitudes, and skills of the PKM partners as indicated by an increase in the post-test scores when compared to the pre-test scores. In addition, there was also an increase in the degree of public health with a decrease in blood pressure, especially in participants who suffered from hypertension after being treated with celery leaves.
