description: Daun ubi jalar yang merupakan hasil samping budidaya tanaman ubi jalar,  dilaporkan banyak mengandung komponen bioaktif yang berpotensi  menyehatkan, akan tetapi morfologi daun tersebut sangat bervariasi. Perbedaan  morfologi ini mempengaruhi tingkat penerimaan untuk dikonsumsi. Oleh karena  itu penelitian ini bertujuan untuk mengetahui : (1) klon daun ubi jalar yang paling  disukai konsumen; (2) aktivitas antioksidan dari berbagai klon daun ubi jalar.  Penelitian ini disusun menggunakan Rancangan Acak Lengkap (RAL) dengan tiga  kali ulangan. Perlakuan pada penelitian ini terdiri atas daun ubi jalar klon  Ayamurasaki, LPG-21, LPG-01, LPG-02, LPG-11 dan LPG-15. Pengamatan yang  dilakukan pada penelitian ini meliputi pengujian sensori dan pengujian aktivitas  antioksidan metode DPPH dan FRAP. Hasil penelitian menunjukkan bahwa ; (1)  Daun ubi jalar klon LPG-01 memperoleh score tertinggi yaitu memiliki tingkat  kesukaan panelis paling tinggi dengan skor warna 3.23 (agak suka), skor aroma  3.23 (agak suka), skor rasa 3.03 ( agak suka), skor tekstur 3.43 (agak suka), skor    kunyahan 3.07 (agak suka), skor aftertaste 3.13 (agak suka) ; (2) Pengujian  aktivitas antioksidan menunjukkan daun ubi jalar klon LPG-01 memperoleh score  tertinggi pada metode DPPH dengan persentase aktivitas antioksidan 81.77%  dan% dan nilai IC50 132.83 μg/l persentase aktivitas antioksidan dan pada metode  FRAP dengan nilai FRAP 50.56 mg AAE/ g ekstrak.    Kata kunci: aktivitas antioksidan, daun ubi jalar, DPPH, FRAP, klon Sweet potato leaves, which are the byproducts of sweet potato cultivation, are  reported to contain many bioactive components that have potential health benefits.  However, the leaf morphology varies greatly. This morphological difference  affects the level of acceptance for consumption. Therefore the aim of this research  is to identify: (1) Sweet potato leaves clones that are most preferred by  consumers; (2) Antioxidant activity of sweet potato leaves of various clones. This  research was comducted in Completely Randomized Design (CRD) with three  replications. The treatments were consisted of the leaf of Ayamurasaki clone of  sweet potato, LPG-21, LPG-01, LPG-02, LPG-11 and LPG-15. The observed  parameters were sensory properties and antioxidant activity test performed with  DPPH and FRAP assays. The results showed that; (1) The leaf of sweet potato  plant of clone LPG-01 has the highest color score of 3.23 (moderately liked),  aroma score of 3.23 (moderately liked), taste score of 3.03 (moderately liked),  texture score of 3.43 (moderately liked), mastication score of    3.07 (moderately liked) aftertaste score of 3.13 (moderately liked); (2) The  antioxidant activity test showed that the leaf of LPG-01 clone of sweet potato has  the highest score in DPPH method with the antioxidant activity percentage of  81.77%, and IC50 value 132,83 μg/ mL while in FRAP method with FRAP value  of 50.56 mg AAE/g of extract.    Keywords: antioxidant activity, clone, DPPH, FRAP, sweet potato leaf
