True seed of shallot (TSS) can be an alternative source of shallot seeds. But the use of TSS in Indonesia is still limited because not many people produce TSS because of high input production. This research aimed to evaluate the technical and economic feasibility of input saving TSS production technology packages. The research was carried out in Ciwidey district, Bandung Regency, West Java, Indonesia from June to October 2016. The research consisted of two factors arranged in a split plot with a randomized block design and eight replications. The main plot was technology packages, namely farmer, recommendation and input saving. The subplot was harvest time, which were 80, 90, and 100 weeks after planting. The observed variables were yield component and yield, soil status, climate data, and farming data. The technical data were analyzed by ANOVA test and continued using the Duncan test at a 95% confidence level. Farming data was analyzed by RC ratio. The results showed that input saving package did not meet seed standards with an RC ratio of 1.07. Savings input on TSS production in Indonesia were only possible by choosing the right location and planting time and must be followed by climate prediction.

<p>Indonesia memiliki keragaman sumber daya genetik ubi jalar yang tinggi dengan jumlah yang cukup banyak dan tersebar diseluruh wilayah dengan variasi hayati yang tinggi, termasuk di Jawa Barat. Karakterisasi dapat digunakan untuk mengetahui dan menganalisis keragaman sumber daya genetik ubi jalar. Tujuan penelitian ini untuk mengetahui karakter morfologi penciri keragaman sumber daya genetik ubi jalar yang tumbuh di wilayah Provinsi Jawa Barat. Penelitian dilaksanakan pada bulan Januari-Desember tahun 2016. Karakterisasi pertanaman ubi jalar dilakukan secara in situ di Kabupaten Kuningan dan Kabupaten Sumedang, Jawa Barat. Karakterisasi dilakukan terhadap 8 aksesi ubi jalar, yaitu (1) Bocil, (2) Bolu, (3) Ase Putih, (4) Ancret, (5) Mano, (6) Rancing ST 1, (7) Rancing ST 2, dan (8) Rancing ST 3. Analisis karakter morfologi yang diamati terdiri atas morfologi daun, batang, bunga, dan umbi sesuai dengan deskriptor ubi jalar. Analisis data menggunakan Analisis Komponen Utama<br />(Pricipal Component Analysis-PCA) serta Analisis Klaster/Cluster Analysis. Data dianalisis dengan bantuan program Minitab 16. Hasil penelitian menunjukkan bahwa terdapat lima komponen utama dengan proporsi keragaman 96,8 %. Sumber daya genetik ubi jalar di Jawa Barat terbagi ke dalam dua klaster pada derajat kemiripan 30%. Keragaman sumber daya genetik ubi jalar di Jawa<br />Barat dapat diidentifikasi melalui karakter penciri panjang dan diameter ruas batang; bentuk daun; tipe, jumlah, dan bentuk pusat cuping; warna pucuk daun; panjang dan warna tangkai daun; warna kulit utama; warna daging umbi utama; dan bentuk helaian bunga.</p>

The low production of Atlantic as processed variety has prompted efforts to introduce varieties as well as the creation of new varieties. The purpose of this study was to examine various alternatives of processed potato varieties that have the potential in the highlands of Garut, West Java. The research was conducted in Cikajang, Garut, West Java, from December 2017 to March 2018. The research used a randomized block design with eight varieties and four replications. The varieties tested were Blis, Atlantic M., Medians, Granola L, AR8, AR7, Amabile, and Atlantic. The observed variables were height plant at 2, 4, 6, and 8 WAP, number of tuber by size, and tuber weight. The data was tested with the F test and if it was significantly different, it was continued with the orthogonal contrast test at the 5% level. Heatmap analysis was performed using the R Studio program The result showed that Granola was not significantly different from all processed varieties. There were three groups of processed varieties, namely the first group, Amabile. The second was AR 7, Medians, and Blis. The third was Atlantic M, Atlantic, and AR 8. Amabile variety had the highest production and number of large tubers.
