 ABSTRACT The purpose of this study was to determine the cost structure and benefits of sweet potato processing business types in Pagar Alam City, and to find out of the sweet potato processing business in Pagar Alam City was feasible. This research was carried out in Pagar Alam City from January until March 2018. The research method used is Case study, for sampling methods used with Purposive Sampling. Data anaysis using quantitative descriptive methods. The results showed that the potential for developed a sweet potato processing business in the city of Pagar Alam was seen from the structure of costs and benefits, the production costs incurred by UMKM sweet potato processing business amounted to Rp. 5,736,566.00 / month consisting of a fixed cost of Rp. 1,276,900.00 / month and variable costs of Rp. 4,459,000.00 / month. The profits obtained by UMKM sweet potato processing business amounted to Rp. 9,303,433.00 result from the difference in revenue of Rp. 15,040,000.00 with a production cost of Rp. 5,736,566.00. Business of processing  Sweet potato which is carried out by UMKM in Pagar Alam City is feasible to be seen from the acceptance of Rp. 45,120,000.00 greater than the BEP revenue of Rp. 5,445,365 65. Production of 1,040 kg is greater than BEP production of 97.43 kg. Price of Rp. 43,000.00 is greater than BEP for Rp 16,547.78. B / C of 1.62 is greater than 1.00.ABSTRAK Tujuan penelitian ini adalah untuk mengetahui struktur biaya dan keuntungan jenis-jenis usaha pengolahan ubi jalar di Kota Pagar Alam, dan untuk mengetahui apakah usaha pengolahan ubi jalar di Kota Pagar Alam layak dikembangkan. Penelitian ini dilaksanakan di Kota Pagar Alam dari Januari sampai Maret 2018. Metode penelitian yang digunakan adalah studi kasus (case study), untuk metode penarikan contoh digunakan dengan sengaja (Purposive Sampling). Analisis data menggunakan metode deskriptif kuantitatif. Dari hasil penelitian menunjukkan bahwa potensi pengembangan usaha pengolahan ubi jalar di Kota Pagar Alam di lihat dari struktur biaya dan keuntungan, biaya produksi yang dikeluarkan oleh UMKM usaha pengolahan ubi jalar sebesar Rp 5.736.566,00/bulan yang terdiri dari biaya tetap sebesar Rp. 1.276.900,00/bulan dan biaya variabel sebesar Rp  4.459.000,00/bulan. Keuntungan yang diperoleh oleh UMKM usaha pengolahan ubi jalar sebesar Rp 9.303.433,00 yang dihasilkan dari selisih penerimaan sebesar Rp 15.040.000,00 dengan biaya produksi sebesar Rp 5.736.566,00. Usaha pengolahan ubi jalar yang dilakukan UMKM di Kota Pagar Alam layak diusahakan dilihat dari penerimaan Rp 45.120.000,00 lebih besar dari BEP penerimaan Rp 5.445.365,00. Produksi 1.040 kg lebih besar dari BEP produksi 97,43 kg. Harga Rp. 43.000,00 lebih besar dari BEP harga Rp 16.547,78. Nilai B/C 1,62 lebih besar dari 1,00.

The study was conducted to analyze constraints to adoption of sweet potato processing technologies among actors in South East, Nigeria. Questionnaire was used to collect data from a sample of eighty (80) respondents used for the study. Data were analyzed using mean score, standard deviation, factor analysis and multiple linear regression analysis. Results indicated that sex, educational level, marital status, processing experience and access to extension service had a positive influence on the adoption of sweet potato processing technologies in the study area. The respondents were highly constrained by inadequate processing machines/equipment (=2.88), high cost of processing produce (=2.86), inadequate knowledge of modern sweet potato processing techniques (=2.84), inadequate capital for start-off (=2.84), high cost of labor (=2.83), poor credit facilities (=2.80) and scarcity of processing materials like sweet potato tubers (=2.43). These variable constraints were further subjected to factor analysis and the variables were named technical and infrastructural factors. It is recommended that processors should be encouraged to form cooperative society to enable them to pool their resources together to obtain credit facilities and sweet potato labour saving processing technologies in order to increase productivity. There is also a need for creation of awareness by extension agents, public health agencies, nutritionists and non-governmental organizations on the usefulness of orange fleshed sweet potato in addressing Vitamin A Deficiency Syndrome.

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)
