Abstract

Peoples of Traditional Cikondang Village, located in the village of Lamajang, Pangalengan, Bandung City West Java have a very close relation to the environment along with its natural resources. This relation is expressed in the form of procedures and rules on the management and utilization of landscape units as well as the diversity of plants as a form of adaptation to the natural environment. This research was conducted through ethnographic method for photographing people’s lives and ethnobotany to know the biological resources that are important to Cikondang’s people’s daily lives. Descriptive and analytical methods are used through interviews with 87 respondents and 4 key informants. Results of research on landscape units that were identified by the community, indicates that in terms of the character, function, and its management there are 9 units of landscape that is both natural landscape and which has been modified by Cikondang community activities. Each unit of the landscape is characterized by vegetation cover according to the type of value in order for daily life. Meanwhile, cultural factors, economic, and political could be a trigger to the landscape transformation of one type of landscape into other landscapes.

Abstract

Selaginella, a genus of Pteridophyte, is known as an herb that contains of several bioactive compounds. The growth and bioactive compounds of plant were affected by plant environment, such as media types. The objective of the research was to obtain an appropriate plant media for growing S. plana dan S. willdenovii, and its effect on the content of bioactive compounds. The experiment consisted of two factors, plant growth media and the species of Selaginella. The first factor consisted of eight plant growth media, i.e.: soil, rice husk, rice husk : soil = 1:1 (v/v), burned rice husk, soil : burned rice huks = 1:1 (v/v), burned rice husk : rice husk = 1:1 (v/v), burned rice husk : rice husk = 3:1 (v/v), and burned rice husk : rice husk = 1:3 (v/v). The second factor was two spesies of Selaginella, i.e.: S. plana and S. willdenovii. Ethanol extract of Selaginella was qualitatively analyzed for flavonoid, tannin, and saponin content. The result showed that both fresh and dry weights of Selaginella were influenced by the type of plant media, Selaginella species, and their interactions. S. plana and S. willdenovii grew best on medium containing soil: burned rice = 1:1 (v/v). The highest flavonoid content of S. plana and S. willdenovii was also obtained from the plant grown on the same media. Comparing to the bioactive compound content of natural plant, saponin content of S. plana and S. willdenovii was increased by the treatment of plant media. The treatment also increased tannin content of S. plana, but not of S. willdenovii.

Abstract

Lidah mertua (Sansevieria sp.) Blue Leaf is a slow growing ornamental plant. It is also difficult to reproduce. Therefore market demands for this plant is impossible to fulfill through conventional methods of propagation such as leaf cutting or layering. Tissue culture is one of the alternatives to solve the problem of plant propagation. In vitro culture of Sansevieria calli was induced for shooting, and rooting afterwards. The basic media of WP was superior than MS in producing multiple shoots, and this WP media containing of BAP 5 mg/L and NAA 0,5 mg/L (WH1) gave the highest number of shoots and leaves on plantlets, as well as the best growth performance. The shoots started to appear two weeks after culture. Plantlets from WH1 rooted in higher frequency as well on rooting media. A mixture of compost, sand, and zeolit (4:4:1) enriched with a nutritive solution, composting of 1⁄4 WP plus IBA 0.5 mg/L, was a poreous media that was able to induce rooting of this plant.

Abstract

Herbaceous plants are able to flower any time, give them opportunity to interact with insects. This study aimed to analyze the diversity of pollen collected by Trigona sp. in herbaceous ecosystem and counted the percentage of pollen viability from the pollen basket. Trigona’s nest was adapted at plot and the herbaceous plants with their pollen were identified. Pollen were took from hind legs at 07.00, 08.00 and 09.00 am. Pollen slide were make by acetolysis and SEM methods. Pollen were identified and examined of viability. Identification herbaceous plants and their pollen on plot showed that there were 7 herbaceous plants: Kyllinga monocephala, Cleome rutidosperma, Pennisetum polystachyon, Ageratum conyzoides, Brachiaria mutica, Cyperus orodatus, and Eleutheranthera ruderalis. Otherwise pollen which were collected by Trigona sp. consist of 11 kinds of pollen from 6 families, that were Sapindaceae, Leguminoceae, Loranthaceae, Malvaceae, Symplocaceae, and unidentified family.Viability of pollen ranged from 88.8% to 99.8%. The result of identification herbacious plants and pollen that were taken by Trigona sp. indicated that there was not similarity therefore, it was no interaction between herbaceous plants in the plot with Trigona sp.

Abstract

The development of industrial fermentation food could not separate with the availability of culture starter that suffice to support its production. Dried starter can be an option to use in fermentation industry because it can be stored for longer time without rejuvenation. However, in the process of production of dried starter needs the matrix to maintain cell viability, economically and availability of raw material. This research was conducted to use selected dried starter of indigenous lactic acid bacteria by using sour cassava starch matrix. Eleven local isolates lactic acid bacteria isolates from spontaneous fermentation of carbohydrates commodity were selected based on their acid production capabilities and antibiotics susceptibilities. Isolate of E 1222 showed the best result and was identified as Pediococcus pentosaceus. The isolate was encapsulated with sour cassava starch matrix for making dried starter by using freeze dryer and spray dryer. Freeze dried starter culture could maintained the cell viability higher than spray dried starter culture i.e 10.34 log CFU/g and 8.91 log CFU/g, respectively. Finally, freeze dried starter culture could maintain the percentage of cell viability until 89.38% during four-weeks storage at 4 oC.

Abstract

Sansevieria trifasciata is an unique houseplant that can provide clean air to occupied room because it can absorb harmful substances from the air. This research aim to compare morphological, and anatomical characters and chlorophyll content of five cultivars of this plant. Morphological characters of all S. trifasciata cultivars observed varied in pattern, colour, and size of the leaf. Stomata can be found on both leaf surfaces; abaxial side have higher stomatal density than adaxial side. Distribution of single stomata was presented in all cultivars, while clustered stomata were also found in cv. Moonsine. Among all cultivars, stomatal density and stomatal index were found the highest in cv. Moonsine. The highest chlorophyll content, the longest leaf, widthest leaf and the thinnest leaf were found in cv. African Dawn. Potentially, S. trifasciata cv. African Dawn and S. trifasciata cv. Moonsine could absorb air pollution better than the other cultivars.

Abstract

Paraserianthes falcataria sawdust (SGS) and oil palm empty fruit bunch (TKKS) are by-product of forestry and oil palm industries. SGS is commonly substrates for mushroom cultivation. TKKS is expected to be an alternative substrates for mushroom cultivation besides SGS. This study was conducted to determine the growth and fruiting body production of Lentinus sajor-caju LSC9 isolate on SGS, TKKS and mixtures of both substrates (C) with proportion 1:1 respectively. Each substrates were added with 15% rice bran, 1.5% gypsum and 1.5% CaCO3 with a total weight of 500 g/bag. The result showed that the growth and fruiting body production of Lentinus sajor-caju LSC9 isolate on SGS was better than TKKS and C substrates with biological efficiency on SGS substrates (50.88%) higher than TKKS substrates (34.42%) and C substrates (29.51%), with vegetative phase (16 days), generative phase (100 days) and growth and development phase (115 days) on TKKS substrates were shorter than SGS and C substrates. The greatest pileus number found on SGS substrates (12 pieces), while the largest pileus diameter found on C substrates (10.17 cm). Nevertheless, TKKS can be used as alternative substrates for fruiting body production of Lentinus sajor-caju LSC9 isolate.

Abstract

Utilization of marginal lands such as tidal land should be done to increase rice production as a solution of the decreasing productive land. However, rice cultivation in such land will be affected by low soil fertility, soil acidity and Fe toxicity. Fe-tolerant varieties are needed to overcome those problems. The objective of the research was to analyze the growth and production of Fe tolerant rice lines in tidal soil type C, Banyuasin, South Sumatera. Screening for Fe-tolerant character of 54 rice lines from the F8 RIL population derived from a cross between rice var. IR64 and var. Hawara Bunar using hydroponic technique under 1000 ppm Fe resulted 25 Fe-tolerant lines. The field test of 25 putative tolerant rice lines, at the tidal land in Banyuurip, Banyuasin, showed that the most lines grew better than that of var. Hawara Bunar parent. Several lines produced yield higher than that of var. Hawara Bunar parent. The field experiment resulted two rice lines, which were IRH108 and IRH195 that potential for further studies.
