Abstract

Sweet potato is raw locally food used as an alternative staple food that important for national food security.   The objective of the reseach was to achive the suitable medium for preservation  of  sweet potato plants by slowly growth in in vitro medium.   The factorial experiment arranged in completely randomized design with the first factor was two concentrations of MS medium: MS 1 and MS 2.   The second factor was several concentrations of coconut water, i.e.  0 and 15 mg/l and the third factor was several concentrations of Aspirin (0, 5, 10, 15, 20 mg/l) . The results showed that the number of green leaves and the number of internodes were affected by concentrations of medium in six weeks after planting. The MS1 medium with 0 mg/l Aspirin and 15 mg/ coconut water could produced the higher number of green leaves (8,0) and 8,5 internodes number.  The MS2 + 15 mg/l coconut  water and 15 mg/l Aspirin was the best medium for sweet potato preservation.   Data obtained also showed that all medium containing Aspirin  produced  the high number of root.  Keywords : Sweet potato, coconut water, Aspirin, preservation, in vitro.

Abstract

Nepenthes plant is a unique plant due to its interesting pitcher at the leaf tip. The objective of the research was to determine the suitable MS (Murashige and Skoog) medium concentration for growth of two species of nepenthes and induction pitcher formation.  A factorial experiment arranged in completely randomized design was carried out with the first factor was two species of Nepenthes; N. ampullaria and N. mirabilis.  The second factor was several concentrations of MS medium, i.e.  0.500 MS, 0.250 MS, 0.125 MS, 0.0625 MS and 0.000 MS. The results showed that the number of leaves, the number of pitchers were affected by the type of Nepenthes and MS medium while plant height only affected by type of Nephenthes. N. mirabilis had significance higher number of leaf of 13.47 compared to N. mirabilis of 11.10. However, number of pitchers formed was lower in N. mirabilis compared to N.ampullaria.  Data obtained also showed that the best MS medium for pitcher formation was 0.0625 MS medium.  Keywords : Nepenthes ampullaria, Nepenthes mirabilis, pitcher plant, MS medium

Abstract

Coffee husk is the main waste of coffee bean production using a dry processing system. Coffee husk is returned to the coffee plantation as mulch, or used as a mixture for nursery media and for making bio-charcoal. This study aims to determine the effect of the formulation of biochar, coffee husk, and soil on the growth of Arabica coffee seedlings. The experiment used a randomized block design (RBD) consisting of 6 treatments with 4 replications. The treatments were the composition of the ratio of biochar: coffee husk: soil (v / v / v), namely: 0: 1: 2 (control, without biochar), 1: 1: 2, 1: 0: 2 (without coffee skin), 2: 1: 2, 1: 2: 2, and 1: 1: 1. The coffee husk biochar is made by a slow burning system in a stack. The results showed that: (1) The treatment of biochar composition, coffee husk and soil had an effect on the number of leaves, length x leaf width, crown dry weight, fresh weight quality index, and dry weight quality index; (2) biochar mixing treatment did not increase seedling growth. Mixing biochar with a composition of 1: 1: 2 reduces root growth; (3) the composition of biochar, coffee husk and soil 1: 1: 2 gave better seedling growth than the composition 0: 1: 2 (control without biochar) based on the quality index of fresh seedling and dry seedling.Keywords: Arabica, biochar, coffee husk, growth, seedling, quality indeces

Abstract

Indonesia is one of the largest cassava producing countries in the world with various types and advantages. Waxy clones have a high starch content and therefore they can be used as a food substitute for rice. Tissue culture through somatic embryogenesis is an effective technique for rapid and mass seedling propagation. This research aimed to determine the effect of the type and concentration of auxin 2,4-D or picloram and the addition of NAA on the formation of Waxy cassava clone somatic embryos. This research used a completely randomized design (CRD) which was arranged in a non-factorial. Auxin 2,4-D and picloram were used at four concentration levels: 0 mg.l-1, 8 mg.l-1, 10 mg.l-1, 12 mg.l-1, and additional NAA treatment of 6 mg.l-1 each. Results showed that MS + 6 mg.l-1 NAA treatment produced the highest callus weight. Meanwhile, the percentage of embryonic callus and number of embryo was higher in the treatment of MS + picloram 12 mg.l-1 and NAA 6 mg.l-1 (19,05 ± 5,82 %) and MS + 8 mg.l-1 2,4-D + 6 mg.l-1 NAA (11,11 ± 3,17 %) with 5,48 ± 3,56 and 4,93 ± 1,95 embryos, respectively. Thus, auxin picloram 12 mg.l-1 + NAA 6 mg.l-1 were the most effective in inducing the formation of somatic embryos on waxy cassava clone.

Abstract

Cassava is a plant that is ranked third as a source of food in Indonesia. Apart from that, cassava is also needed in industries such as making tapioca flour. In 2021, cassava production in Lampung will be around 20-25 t/ha, this amount is still below the potential of superior cassava which reaches 35-40 t/ha. Cassava growth and production depend on the variety and land where it is cultivated. This research aims to determine the differences in growth and production of several early maturing cassava clones tested, namely Vamas-1, Vati-1, and UTK on Ultisol soil in the PT GGP research area. This research was carried out on the land of the PT GGP research division, Central Lampung, Lampung. This research was carried out from August 2022 to February 2023. The research method used was a Randomized Block Design (RAK) with one treatment, namely clones. There are 3 clones used, namely Vamas-1, Vati-1, and UTK. The experiment on each clone consisted of 3 replications with 36 plants in each replication, but 5 plants were selected from each replication as samples, so that 45 experimental units were obtained. The observation data was analyzed and then compared with the UJ5 clone data based on the Standard Deviation to determine the early maturation characteristics of the three clones. The results showed that clone treatment had no significant effect on growth and production. The number of fresh sweet potatoes at 24 weeks after planting (WAP) in terms of the quantity of clones Vamas-1, Vati-1, UTK, and UJ5 respectively was 7.3; 6.6; 6.3; and 7.3 fruit/plant with a fresh sweet potato weight of 2316,7; 2183,3; 2150,0; and 1433,3 g/plant. The starch content of Vamas-1, Vati-1, UTK, and UJ5 clones was 26,2%; 25,2%; 25,8%; and 23.2%..Keywords : early, Manihot esculenta, UTK, Vamas-1, Vati-1,
