Abstract

Sweet potato (Ipomoea batatas L.) with orange flesh enriched with β-carotene andvitamin A can help combat vitamin A deficiency and malnutrition, especially forcommunities in developing countries. The purpose of this study is to select local sweetpotatoes from Lampung which contain β-carotene and to determine an appropriate harvestage to obtain high β-carotene content and production. The study was conducted at theLampung State Polytechnic using a randomized block design (RAK) repeated 2 times.The treatments consisted of 30 genotypes of sweet potato germplasm and 2 harvest ages(3 months after planting and 4 months after planting). The 30 genotypes were selectedbased on flesh color (yellow to dark orange), then tested for β-carotene content andproduction at 3 months and 4 months of harvest. The results showed that from 30genotypes, there were 16 genotypes that had yellow to dark orange flesh color. Thecontent of β-carotene, tuber weight per plant, and number of tubers per plant were higherat 4 months harvest than 3 months harvest. The LPG-01 genotype (Local Lampung) at 3months of harvest had a higher β-carotene content than the other genotypes, which was1,902 µg /100g, while at 4 months the β-carotene content was almost equivalent to theBeta-1 genotype, but higher when compared with other genotypes with 40,493 µg /100g.Genotype of LPG 01 had tuber weight (1,191.90 g per plant) and the number of tubers(5.63 bulbs per plant) higher than the other genotypes. Key words: β-carotene, production, sweet potato, harvest age.

Abstract

Data from the Directorate of Serelia Cultivation shows that Indonesia's sorghum production in the last 5 years has only increased slightly from 6,114 tons to 7,695 tons. The increase in domestic sorghum production needs special attention because Indonesia has great potential for sorghum development (Subagio and Aqil, 2013), therefore it is necessary to respond to the growth and production of sorghum (Sorghum Bicolor L. moench) plants to the application of cow dung bokashi fertilizer and weeding time in the Lebak swamp. This study aims to determine the response of growth and yield of sorghum plants. This research has been carried out by Lr. Karang sublime, Talang Putri Village, Plaju District, Palembang. The design used was a randomized block design (RAK) which was arranged in a factorial manner consisting of two factors, namely the weeding time factor (P) and the cow dung bokashi fertilizer dose factor (K). The treatment factor for weeding time consisted of 3 levels, namely P1 (7 DAP), P2 (14 DAP), P3 (21 DAP) and the dose treatment factor for cow dung bokashi fertilizer consisted of 3 levels, namely K1 (bovine bokashi fertilizer 100g per plant). K2 (bovine dung bokashi fertilizer 150g per plant), K3 (cow dung bokashi fertilizer 200g per plant), so there were 9 treatment combinations with 3 replications/group, where each treatment consisted of 27 plants with 4 sample plants. The variables observed in this study consisted of 1) plant height (cm), 2) flowering age (days), 3) fruit weight (g). The results showed that the treatment of weeding time for 14 days after planting and the application of 200g cow dung bokashi fertilizer per plant had a significant effect on all observed variables.
