Doyo (Curculigo latifolia) which grows wild in nature is one of the important plants in East Borneo which was many benefit, one of them as as raw material of ulap doyo?s woven fabric. This research was aimed to perform domestication stages by looking at the initial vegetative growth process of doyo plants in one location. Doyo accession was obtained at 15 location points from 6 sub-districts (Tenggarong, Bangun City, Muara Wis, Anggana, Bongan and Jempang) which were then carried out domestically on experimental land in Bukit Biru Village, Tenggarong District. This research used a randomized block design with a single factor were doyo accession (6 accessions). Observation data were analyzed with F test (?=5%) and continued DMRT (Duncan Multiple Range Test) using SAS v. 11.6. The results showed that the highest percentage of live doyo accession in polybags was obtained at Bongan accession (85.16%), while the lowest was obtained at Kota Bangun accession (32.42%). Meanwhile, when planted in the field of research, based on the results of variance showed that the treatment of accession had a significant and very significant effect on the parameters of height increase of plants at 1 and 2 month after planting (WAP), increase in stem diameter, length of leaf midrib, leaf stalk length, leaf length, width leaves, and the number of new leaves at 1-3 MAP, but not significantly different from the parameters of plant height increase at 3 MAP and number of tillers. The highest leaf length was obtained at Bongan accession, while the highest leaf width ang number of new leaves were obtained at Tenggarong accession.

Seleksi in vitro bisa diterapkan pada berbagai kondisi cekaman abiotik misalnya cekaman terhadap aluminium dengan menggunakan agen seleksi AlCl3. Penelitian ini bertujuan untuk menentukan lethal concentration 20 (LC20) dan LC50 dalam rangka seleksi in vitro terhadap toksisitas aluminium dengan menggunakan agen seleksi AlCl3. Penelitian terdiri atas empat percobaan yang terpisah, masing-masing menggunakan genotipe Jame-jame, UJ 5, Adira 4, dan Gajah sebagai bahan tanam (eksplan). Percobaan ini disusun berdasarkan rancangan acak lengkap satu faktor. Faktor perlakuan adalah konsentrasi AlCl3 (0, 100, 200, 400, 600 dan 800 mg L-1). Hasil seleksi in vitro menunjukkan bahwa genotipe Jame-jame dan Gajah relatif peka terhadap toksisitas aluminium dibandingkan genotipe Adira 4 dan UJ 5. Hal ini dapat dilihat dari kepekaan kalus genotipe Jame-jame (LC20 = 19,39; LC50 = 236,37) dan Gajah (LC20 = 39,99; LC50 = 289,10) terhadap pemberian AlCl3 dibandingkan kalus genotipe Adira 4 (LC20 = 831,88; LC50 = 2897,10) dan UJ 5 (LC20 dan LC50 belum teridentifikasi hingga konsentrasi maksimum AlCl3).Kata kunci : AlCl3, seleksi in vitro, toksisitas aluminium, ubi kayu

This research was aim to know the effect using of composts and liquid organic fertilizer concentration toward the growth and yield of soybeans. This reasearch starts from April to July 2017, located Rempanga village, Kutai Kartanegara District.The study was arranged by randomized complete block design (RCBD) factorial 3 x 4 with 3 (three) replication. The first factor was compost doses with 3 levels i.e k0 = control (without using of compost), k1 = 15 t ha-1 (120 g plant-1), k2 = 30 t ha-1 (120 g plant-1). The second factor was the concentration of liquid organic fertilizer with 4 levels i.e. p0 = control (without using of liquid organic fertilizer), p1 = 20 mL L-1 water, p2 = 40 mL L-1 water, p1 = 60 mL L-1 water.The treatment of compost had no significant to the average of number of planted pods and the number of empty pods per plant but significantly different in weight of crop seeds with the highest weight obtained at the k2 treatment (17,167 g).The treatment of concentration of liquid organic fertilized had no significant effect on the average of number of empty pods and the number of empty pods per plant and weight of seeds. The highest weight obtained at the p3 treatment (15,222 g).The interaction between compost and a liquid organic fertilizer concentration had no significant to the average of number of planted pods, number of empty pods per plant and weight of seeds. The highest weights are obtained in the combination of k2p3 treatment (20,500 g).

This study aims to determine the effect of eggshell powder fertilizer and the concentration of ZPT Root-up on the growth of super red dragon fruit stem cuttings (Hylocereus costaricensis). This research was conducted from October to December 2018 starting from the preparation of planting media to the end of the study. The research location is located in Sukodono Hamlet, Sumber Sari Village, Loa Kulu Subdistrict, Kutai Kartanegara Regency.This study was arranged in a Randomized Block Design (RBD) with a 3x4 factorial analysis with replications 3 times. The first treatment factor was the administration of ZPT Root-up (P) which consisted of three levels, namely: p0 = no treatment, p1 = 100 ppm Root-up, p2 = 200 ppm Root-up. The second treatment factor is the administration of eggshell powder (T) which consists of 4 levels, namely: t0 = no treatment, t1 = 12.5 grams of polybag-1 eggshell powder, t2 = 25.0 grams of polybag-1 eggshell powder, t3 = 37.5 grams of polybag-1 eggshell powder.The results showed that administration of eggshell powder fertilizer had no significant effect on the time of first shoot (day), length of shoots 40 days, number of shoots 40 days and 80 days. But it has a very significant effect on the parameters of root length (cm). The results showed that the administration of ZPT Root-up concentrations had no significant effect on the time the first shoot appeared, but had a very significant effect on shoot length 60 days, 80 days, 80 shoots, root length (cm), and root weight (g). The results showed that the effect of eggshell powder interaction and ZPT Root-up had no significant effect on any plant parameters observed.

Doyo plants are expected to produce offspring or generations that are able to adapt well in a new growing environment. The generation of doyo accessions that managed to grow well in the new environment was then passed on as propagation material to produce the next generation so that a large number of plant propagation materials were obtained for large-scale cultivation. This study aims to observe the continued growth of doyo accessions as a result of domestication. This research consisted of two experiments. The first experiment was to see the growth of tillers from 6 doyo accessions (Tenggarong, Kota Bangun, Muara Wis, Jempang, Bongan, Anggana). The second experiment was to see the growth of the first generation of doyo accessions from domestication. The planting material used was tillers of doyo accession originating from the first experiment grouped into 3 groups based on the age of the tillers: group 1 (0 - <3 months), group 2 (3 - <5 months), group 3 (5 - <7 months). Data in the first and second experiments were analyzed by the F-test (?=95%) and then tested further using the DMRT (Duncan Multiple Range Test) test using SAS v. 11.6 software. In the first experiment, the analysis showed that the treatment of accession had no significant effect on the number of tillers at 3 to 6 months after planting (MAP), but had a very significant effect at 12 MAP. The highest average number of tillers at 12 MAP obtained at Bongan accessions (9.75 tillers), but not significantly different from Kota Bangun accessions (6.11 tillers) and Jempang (6.67 tillers), while the lowest average number of tillers was obtained at Anggana accessions (1.57 tillers) but not significantly different from Muara Wis accessions (3.33 tillers). In the second experiment, the results of the analysis showed that the treatment of accession had no significant effect on increasing the diameter of the stem, increasing the length of the leaf, and increasing the number of leaves, but significantly affected the increase in plant height at 2 MAP. In general, it can be seen that seedlings that are still young (0 - <3 months) when used as planting material have a better percentage of life and growth compared to older seeds (3 - <5 months) and (5 - <7 months).
