Telah dilakukan penelitian mengenai efektivitas penggunaan sari buah jeruk nipis (Citrus aurantifolia) dalam mempertahankan kualitas nasi. Tujuan dari penelitian ini untuk mencari kondisi optimum pengawetan dengan sari buah jeruk nipis sehingga dapat mengawetkan nasi dan mengetahui seberapa lama sari buah jeruk nipis mampu mengawetkan nasi yang disimpan dalam alat penghangat nasi. Efektivitas dilihat dari kualitas nasi yang dihasilkan melalui pengamatan jumlah koloni dan sifat fisik nasi. Sari buah jeruk nipis ditambahkan dalam beberapa konsentrasi yaitu 0%, 0,46%, 0,93%, 1,40%, dan 1,87%. Pengamatan sifat fisik nasi dilakukan setiap selang waktu 12 jam berdasarkan perubahan warna, aroma dan rasa. Perhitungan jumlah koloni dilakukan setiap selang waktu 24 jam. Berdasarkan hasil penelitian yang dilihat dari kualitas nasi, dengan mengamati jumlah koloni dan sifat fisiknya, pada konsentrasi 0,93% menunjukkan konsentrasi optimum yang efektif mengawetkan nasi

Abstract A description is provided for Diaporthe citri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Citrus aurantifolia, C. aurantium, C. grandis, C. limon, C. parasisi, C. reticulata and C. sinensis. DISEASE: Melanose of Citrus spp. and stem end rot of the fruit. Symptoms occur on the immature leaves, young branches, stalks and fruit. The very small spots enlarge, become water-soaked, sunken, dark with chlorotic halos and develop raised, corky, superficial, necrotic areas up to 1 mm diam. ; this spotting is frequently very abundant and scar-like, necrotic aggregations are formed; on the fruit the spots are sometimes arranged in rings, lines or curves. Leaves are distorted and may fall prematurely. The small, dying branches bear the same raised spots in which both spore stages are found. Diaporthe citri is one of the citrus pathogens which penetrates the fruit at the stem end and causes a rot in storage (7, 713; 23, 386; 50, 679). GEOGRAPHICAL DISTRIBUTION: Widespread in citrus growing areas (CMI Map 126, ed. 2, 1966). TRANSMISSION: Water-borne through the conidia.
