Abstract
Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained their existence to enrich the types of consumption. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for for children and infants. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions, which were consumed by infants and children, had diverse nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest protein content (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100) were produced by accession Manis. On the hand, accession Saborok produced the highest content of ash (1.32%), vitamin E (28.30 mg/100 g), and B-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) were produced by accession Yuaiken.

Summary
The nutritional rate of sweet potato tubers [Ipomoea batatas (L.) Lamb.] consumed by infants and children of Dani tribe in Kurulu District, Jayawijaya. Penelitian ini bertujuan untuk menganalisis nilai nutrisi ubijalar yang dikonsumsi oleh bayi dan anak-anak di kalangan Suku Dani Jayawijaya. Penelitian ini bertujuan untuk mengetahui nilai nutrisi 4 (empat) aksesi ubijalar yang terutama dikon-sumsi oleh bayi dan anak-anak Suku Dani di Distrik Kurulu Kabupaten Jayawijaya. Kadar serat kasar tertinggi terdapat pada aksesi Yuaiken, yaitu 1,81%, lebih tinggi dari pada hasil penelitian Hartoyo (2004) yang dikutip dalam Elisabeth et al (2007) bahwa kadar serat kasar ubijalar sebesar 1,6 %. Seluruh aksesi yang digunakan untuk komsumsi bayi dan anak-anak memiliki nilai energi lebih tinggi dari hasil penelitian Hartoyo (2004) yang dikutip dalam Elisabethet al. Abu, protein, lemak, serat kasar dan energy pada umbi 4 (empat) aksesi ubijalar yang dikonsumsi bayi dan anak-anak
