Tujuan penelitian ini adalah untuk melakukan pendugaan keragaman klon ubi jalar ungu berdasarkan karakter agronomi dan morfologi tanaman. Percobaan dilaksanakan selama musim hujan di Kebun Percobaan Ciparanje, Fakultas Pertanian Universitas Padjadjaran, Sumedang, Jawa Barat mulai November 2018 sampai April 2019. Perlakuan adalah 11 klon ubi jalar ungu yang berasal dari Indonesia, Peru, dan Jepang. Pengamatan terdiri atas karakter agronomi dan morfologi, serta komponen hasil. Pendugaan keragaman genetik menggunakan analisis klaster, analisis komponen utama, uji mantel, dan perhitungan ragam genotipik dan fenotipik. Hasil penelitian menunjukkan terdapat perbedaan keragaman genetik berdasarkan karakter agronomi dan karakter morfologi. Jarak genetik berdasarkan analisis klaster dan analisis komponen utama pada karakter agronomi dan morfologi masing- masing adalah 0,31–5,18 Euclidean dan 1,73–4,55 Euclidean. Korelasi keragaman agronomi dengan keragaman morfologi sangat lemah (r=0,096). Perhitungan ragam genotipik dan fenotipik juga menunjukkan bahwa keragaman karakter agronomi cenderung luas. </span></p></div></div></div>

Palm oil is one of the most widely produced plantation commodities in the world. World demand for palm oil is also increasing due to the increasing demand for products that use palm oil. This increase ultimately results in the development of the palm oil processing industry which causes the increasing volume of waste produced. Palm oil waste can be utilized and treated as bioenergy so as to add economic value to the waste. The purpose of this paper is to determine the benefits of palm oil waste as bioenergy. The results show that palm oil waste such as shells, empty fruit bunches of palm, fibers, leaves, midribs and Palm Oil Mill Effluent (POME) have several potential contents to be utilized as bioenergy such as biogas, biodiesel, biobriquette, electricity generator, and activated charcoal. Apart from that as bioenergy, palm oil waste can be used as an antioxidant, animal feed, fertilizer and concrete additives.
