Abstract

ABSTRACTThe Ericaceae family has benefit as medicines and ornamental plants, because several types of the Ericaceae family have very attractive colors, fruits and flower shapes, besides that they have important ecological and economic values. This study aims to determine the types and morphology of the Ericaceae family in the Sicikeh-cikeh Lake Nature Tourism Park Lae Hole Village Parbuluan District Dairi Regency Sumatera Utara. This research were conducted in October - January 2020 using the exploration methods, namely by exploring along the path of the research location. The results of studies that have been carried out found 7 types of family Ericaceae, such as 4 of the genus Rhododendron, 1 of the genus Vaccinium, 1 of the genus Diplycosia, and 1 of the genus Cavendishia. The types of the Ericaceae family were found in this study had the same morphology, which has a taproot. The shape of the stem was round, and the direction grows perpendicular (erectus). The leaves are single leaves. Flowers including majmuk flowers, (terminal), and has flower parts, namely the crown of flowers, stamens and pistil. The fruit had a capsule and buni fruit. Keywords : Inventory, Ericaceae Family, Morphology, Sicikeh-cikeh Lake Nature Tourism Park

Abstract

Cilembu Sweet Potato is one type of sweet potato that is typical in the West Java area precisely in the Cilembu village or Sumedang. Cilembu sweet potato has a typical characteristic that is taste like honey if it fermentation and then roasted. Rizospheric bacteria with the ability of phosphate solvents are one of the factors supporting growth in plants. The research aims to identify Rhizosphere bacteria in Cilembu sweet potato roots which have the ability as phosphate solvents at two locations during the growth phase. The study was conducted with qualitative by testing the biochemical characteristics and ability of phosphate solvents. The result of this research show that Rhizosphere bacteria with the ability of phosphate solvents at the location of Cilembu (LCI) and Jatinangor (LJA) are not significantly different. In LCI, 12 isolates were obtained and in LJA 7 isolates were obtained. So that it can be concluded that the diversity of rhizosphere bacteria can be influenced by the characteristics of the soil and the growth phase.Keywords: Cilembu yam, Rizosphere bacteria, phosphate solvent

Abstract

Green mustard plants (Brassica rapa var. Parachinensis L.) are plants that have a source of vitamins and minerals. The purpose of this study was to determine the effect of the concentration of rice grinder and liquid organic fertilizer on the vegetative growth of mustard greens (Brassica juncea L.), to determine the effect of a mixture of Giving POC with plant growth on mustard plants and to determine the effect of a combination of POC and planting media mixture on the growth of mustard plants. This research was conducted in February to May 2020, Jalan Ekarasmi gg. ekanusa in the Kelurahan Gedung Johor, Medan Johor District, Medan City with a height of ± 30 m above sea level using a Random Factorial design consisting of 2 factors and 3 replications. The results showed that the POC concentration did not show a significant effect on plant height, number of leaves, leaf length, leaf width, leaf area, wet weight and chlorophyll of mustard plants, but visually the highest results were obtained at P2 treatment (30 cc / L water ) followed by P1 (15 cc / L water) and the lowest in P0 treatment (without POC), the planting media mixture showed a very significant effect on plant height at 7 and 14 HST and had no significant effect on all other observation variables. The highest yield was obtained in the treatment of M0 (Top Soil Soil) followed by M1 (Top Soil and Rice Husk Mixture) and M3 (Top Soil and Rice bran Mixture) and the lowest in M2 (Top Soil and Bran Soil) mixture, POC and the planting media mixture showed a very significant effect on the plant height variable at 14 HST and the amount of chlorophyll at harvest and had no significant effect on other variables. The best results were obtained on M3 P2 (Top Soil and Rice bran Mixture; P2 (POC concentration of 30 cc / L water).)Keywords: leftover rice mill, liquid organic fertilizer, mustard plant, vegetable pesticide.

Abstract

The aims of the study were: (1) knowing the vegetative growth response of water spinach (Ipomea reptans Poir) due to the treatment of planting media; (2) knowing the vegetative growth response of water spinach plants (Ipomea reptans Poir) due to the method of giving water and (3) knowing the vegetative growth response of kale (Ipomea reptans Poir) due to a combination of planting media and methods of giving water               The research was conducted at Jl. Karya Kasih, Gang. Sawah  No. 1. Kelurahan. Pangkalan  Masyhur, Medan Johor Subdistrict, Medan. with an altitude of ± 30 m above sea level. The research was conducted from December 2020 to February 2021.               The materials used in this study were water spinach seeds, compost and top soil soil, 10 kg polybag of soil and organic pesticides for pest and disease control.               Tools: moisture meter, hands prayer, hoe, machete, saw, title board, plot board and treatment board.               This study used a factorial randomized block design consisting of 3 replications and 2 factors, namely: Factor I. planting medium consisting of two levels, namely: (1) M0 = 100% top soil (100% soil: 0% compost): (2) ) M1 = Compost soil ratio 3: 1 (75% soil: 25% compost) and (3) M2 = Compost soil ratio 1: 1 (50% soil: 50% compost). while, Factor II. Method of Giving Water  (I) which consists of three levels, namely: (1) Po = Field Capacity by giving water once a day; (2) P1 = 3/4 Field Capacity by giving water once a day and (3) P2 = ½ Field Capacity by giving water once a day. Thus there are 9 treatment combinations and 3 replications.               Observed variables include: plant height (cm), number of leaves,   leaf length (cm), leaf width (cm) and plant wet weight (g).               If the results of the variance test show a significant difference from the treatments tried, it can be continued with the Honestly Difference Test (DMRT) method.

Abstract

Parasitic plants were usually considered harmful in the forest ecosystem, the changes of parasities is a counterweight to the ecosystem which is expected to tbe able to give benefits to the community. This study was aimed to determine the types of characteristic of parasitic plants in the natural tourist park of Lake Sicikeh-cikeh which was conducted in Oktober-December 2019 by using exploration method or roaming method and by utilizing qualitative descriptive as data collection techniques. The research result showed that were 7 species of parasitic plants were included become 5 families. those were 2 species of Balanophoraceae family, named (Balanophora papuana Schltr. and Rhopalocnemis palloides Jungh.), 2 species of Loranthaceae family, named (Macrosolen avenis Danser and Scurrula sp). 1 species of Santalaceae family, named (Dendromyza reinwardtiana (Blume ex Korth.) Danser), 1 species of Rafflesia family, named (Rafflesia meijeri Wiriad. & Sari), and 1 species of Orchidaceae family, named (Gastrodia sp.). Based on the characteristics of the hosts, Loranthaceae and Santalaceae family were parasite on tree, Balanophoraceae and Rafflesiaceae were parasite on roots and Orchidaceae family with Gastrodia sp.

Abstract

Citrus is one of the horticultural plants found in Indonesia and is in great demand. The diversity of oranges is very high as indicated by the number of Citrus members. North Sumatra is one of the province with high citrus productivity. Therefore, this study aims to identify the diversity of citrus plants based on their morphological characters in  Nibung Hangus area, Batu Bara, North Sumatra. Data were collected by exploration method. Morphological identification is carried out to assess the morphological diversity of samples taken at the study site, including visual observations of the size, shape and color of plant organ parts. The organs observed included the stems, leaves and fruit of citrus plants. Morphological characterization using the guidelines in IPGRI and the book of Tjitrosoepomo (2002). The data analysis was carried out in a descriptive qualitative. The results showed that there were 5 types of citrus plants found in Nibung Hangus, namely Pamelo Plant (Citrus maxima), Lime Plant (Citrus aurantifolia), Tangerine Plant (Citrus reticulata blanco), Kaffir Lime Plant (Citrus hystrix), and Sunkist Citrus Crop (Citrus sinensis).
