Abstrak. Tanaman cabai merupakan tanaman hortikultura yang buahnya banyak digemari dan dikembangkan di Indonesia. Selain sebagai sayuran, buah cabai juga digunakan sebagai bahan baku obat-obatan, kosmetik serta bahan baku pengolahan makanan seperti saus, sari buah dan lain-lain. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial 5x3 dengan 2 faktor dan 3 ulangan. Faktor yang diteliti ada dua yaitu konsentrasi ekstrak mengkudu (K) dan lama perendaman ekstrak mengkudu (L). Faktor pertama yaitu konsentrasi ekstrak mengkudu (K) terdiri atas 5 taraf yaitu 0%, 20%, 40%, 60%, dan 80%. Faktor kedua yaitu lama perendaman ekstrak mengkudu terdiri atas 3 taraf yaitu 2 jam, 4 jam dan 6 jam. Hasil penelitian menunjukkan bahwa kombinasi perlakuan yang memberikan nilai viabilitas potensial tertinggi yaitu pada perlakuan konsentrasi ekstrak mengkudu 20% dengan lama perendaman 2 jam (K1L1) dengan nilai PTM, DB, Kst dan indeks vigor tertinggi yaitu 93,33%; 81,33%; 70,67% dan 61,33%. Tidak terdapat interaksi diantara perlakuan konsentrasi ekstrak mengkudu dan lama perendaman terhadap persentase kecepatan tumbuh relatif benih cabai kadaluarsa.

Abstract. Chili plant is a horticultural plant whose fruit is very popular and developed in Indonesia. Apart from being a vegetable, chili fruit is also used as a raw material for medicines, cosmetics and food processing raw materials such as sauces, fruit juices and others. This study used a completely randomized design (CRD) with a 5x3 factorial pattern with 2 factors and 3 replications. There were two factors studied, namely the concentration of the noni extract (K) and the immersion time of the noni extract (L). The first factor is the concentration of noni extract (K) consisting of 5 levels, namely 0%, 20%, 40%, 60%, and 80%. The second factor was the immersion time of the noni extract consisting of 3 levels, namely 2 hours, 4 hours and 6 hours. The results showed that the combination of treatments that gave the highest potential viability value was the 20% noni extract concentration treatment with 2 hours of immersion (K1L1) with the highest PTM, DB, Kst and vigor index values of 93.33%; 81.33%; 70.67% and 61.33%. There was no interaction between the concentration of noni extract and the duration of soaking on the percentage of the relative growth rate of expired chili seeds. Keywords: Chili, concentration, noni extract
