Abstract

The population of Mesua ferrea L. in Banyumas Regency, Central of Java Province is very low. There are some factors affecting the quantity of plant population, particularly traditional knowledge of local community about the plant. The aim of this study was to describe the knowledge of Banyumas community about the existence, economic value, usefulness, and propagation technique of M. ferrea. The study was done by field survey on a total of 146 residents from 10 districts which were determined by proportionally stratified random sampling. Data obtained from questionnaires and interviews were analyzed by percentage descriptive. The results revealed that only 9% of respondents were familiar with the M. ferrea and knew its status as plant identity of Banyumas Regency. Most of the respondents did not understand the economic value, only 8% of respondents understood the usefulness, 2% of respondents had utilized the timber as craft material, and 3% understood the propagation technique. The utilization was very low, equal to 14.45% compared to the potential usefulness. Most of the respondents (98%) thought that conservation efforts should be undertaken. This study found that the traditional knowledge of M. ferrea in Banyumas was low. This result should be used as a basic information for developing conservation program of M. ferrea.

Abstract

Xylocarpus granatum is mangrove plant that traditionally used as face powder in Central Sulawesi, Indonesia which related to antioxidant, antiglycation and tyrosinase inhibition activities. This study aimed to evaluate the potency of X. granatum as a tyrosinase inhibitor, antiglycation, and antioxidant. The leaves, stem, stem bark, fruit flesh, fruit peel, and kernel of X. granatum were extracted using ethanol then their tyrosinase inhibition, antiglycation, and antioxidant were evaluated. Tyrosinase inhibition activity was evaluated using in vitro assay with L-tyrosine and L-DOPA as the substrate of monophenolase and diphenolase. Antiglycation activity was studied by measuring the excitation and emission fluorescence from glucose and fructose reaction with Bovine Serum Albumin. Antioxidant activity was measured using the DPPH radical scavenging assay. The result showed that the ethanolic extract of fruit flesh has higher potency as tyrosinase inhibitor (IC50 of 393.8 mg/L and IC50 of 448 mg/L, respectively for monophenolase and diphenolase). Antiglycation assay showed that the ethanolic extract of stem bark provides the strongest antiglycation activity with an IC50 of 118.1 mg/L. Meanwhile, fruit peel provides the strongest antioxidant activity with an IC50 of 5.5 mg/L. Fractionation of ethanolic extracts of each part of X. granatum tree yield fractions with lower bioactivity compared to the crude extract. Moreover, stem extract and fractions from two different locations (Tarakan and Kendari) tend to have different bioactivities strengths.  The stem part of X granatum could be developed as new raw material of cosmetic product in Indonesia, while ethanol as the solvent for extraction, and the different bioactivity of stem extract from different location can be the consideration for the industry to standardize the extract prior to production of final product.

Abstract

East Nusa Tenggara located in the Wallacea area that has many endemic species. However, the existence of germplasm diversity in this area has been threatened due to landscape changes and deforestation. The research was conducted to identify floristic composition in Sikka forest area. This research also aimed to compare that plant composition in Sikka forest area on each of the different altitudes, including their diversity richness and environmental factors. Two sampling methods were used, which are Point-Centered Quarter (PCQ) method that applied for trees and nested sampling method 5x5 m2 for sapling and 2x2 m2 for ground cover. Measured parameters were Relative Density (RD), Relative Frequency (RF), Relative Coverage/dominance (RC), Important Value Index (IVI), Diversity Index (H'), and Jaccard Similarity Index (J’). Research results showed that the diversity index of each region was relatively low. Plant composition of tree, sapling, and groundcover in three different altitudes was quite different. This result indicates that the plant composition in the Sikka, East Nusa Tenggara is very diverse. The temperature and relative humidity in each altitude area observed was significantly different. One of the endemic species of Flores Island, Eucalyptus urophylla, was only found at 500-700 m asl. There are very limited research on the vegetation diversity held in Flores, East Nusa Tenggara. This research can be the basic for further research in order to explore the potential diversity of flora in this area.

Abstract

Roots and tubers are one of the most important crops that provide food security in West Africa. Thus, Pachyrhisus erosus with its various potentials, is planned to be introduced in Benin to improve the nutritional quality of the population. Prior to that, this study aimed at assessing pests and disease of P. erosus in the agroecological conditions in the central parts of Benin. Conducted at experimental field in Savè during two consecutive years, experiments were laid in a completely randomized block design with 4 replications and three treatments including EC 533 and EC Kew cultivars of P. erosus and cowpea variety named Kpodji-Guèguè. Results showed that the major pests collected from P. erosus namely Ootheca mutabilis, Medythia quaterna, Piezotrachelus varium, Megalurothrips sjostedti and Brevipalpus phoenis were not so far reported in it. Compared to cowpea, pest’s infestation and their damages were lower on P. erosus. Infestation severity on leaves and the percentage of perforated green pods ranged from 0.7% to 3% against 0.8% to 88.9% and from 12.5% to 16% against 57.2% to 64% respectively on P. erosus and cowpea. Cercospora disease caused by Cercospora canescens and yam bean leaf blight caused by an unknown fungus were observed. Cercospora disease affected cowpea and P. erosus while yam bean leaf blight affected only P. erosus. This study provides additional data on pests and diseases associated with P. erosus worldwide and alerts farmers regarding their management.

Abstract

Germplasm as a source of genes in sweetpotato breeding requires information on appearance and genetic parameters. The objectives of this research were to determine the performance and genetic parameters of sweet potato accessions. The research was conducted at Kendalpayak Research Station, Malang, East Java, Indonesia. The materials used were thirty sweet potato accessions from Indonesian Legumes and Tuber Crops Research Institute (ILETRI) germplasm collection. The research was arranged in a Randomized Block Design (RBD) with two replications. The variables observed included: the vines length, the weight of vines, the number and weight of the saleable root per plot, the number and weight of the non-saleable root per plot, the number and weight of root per plant, the root yield, the harvest index, and the dry matter content. The results of ANOVA showed a significant difference among the tested genotypes in almost all traits observed except on weight of non-saleable root. PCV estimation was higher than GCV estimation for all the observed characters. The weight of the saleable root per plot, the weight of root per plant, and the root yield that showed a wide range of PCV and GCV as well as high broad-sense heritability indicated that these traits had additive gene effect and more reliable for effective selection. The broad GCV in a population is effective for selection to obtain the superior variety.

Abstract

The traditional use of plants by people in Indonesia has been done since centuries ago. However, there are still many regions that do not already have proper documentation on this matter. This ethnobotany research aimed to analyze the forms of plant utilization and local wisdom in plant management by the indigenous people of Dusun Beleq, Gumantar Village, Kayangan District, North Lombok Regency. This research is a descriptive exploratory survey. Data collection was done by means of observation, interviews, documentation and literature study. Selection of informants was using purposive and snowball sampling methods. Qualitative and quantitative data were analyzed descriptively based on observations, interviews and ICS (Index of Cultural Significance) calculations.There were 10 kinds of plant utilization involving 86 species from 36 families. The plants were used as food, medicine, ritual plants, firewood, fodder plants, construction materials, handicrafts, aromatic plants, dyes and natural pesticides. Most of the plant species was used as food (41 species) with rice (Oryza sativa) as a plant with the highest ICS value among all plants in all categories (74 species). Local wisdom in term of natural resources utilization was reflected in community efforts in forest preservation, plants conservation, plants cultivation and harvesting. The novelty of this study is the revealment of local knowledge in plants utilization possessed by people in traditional village. This results of this study are expected to support the preservation of biological and cultural resources.

Abstract

In Indonesia, soybean is mostly cultivated in lowland following the yearly planting pattern of paddy – paddy – soybean under zero-tillage condition. The research aim was to evaluate the agronomic performance of several soybean genotypes in lowland paddy fields under zero-tillage condition. A total of 12 soybean genotypes, including the check varieties of Wilis and Anjasmoro, were evaluated in lowland after rice planting in three locations (Klaten, Pasuruan, and Tabanan). A randomized block design with four replications was used in each location. The soybean yield is a complex character which determined by interrelated agronomic characters. The averages seed yield in Klaten, Pasuruan, and Tabanan were 2.97 t/ha, 3.02 t/ha, and 2.68 t/ha, respectively. Two genotypes produced equal yield with Anjasmoro, i.e. AT12-1062 (3.01 t/ha) and AT12-1037 (3.0 t/ha). Anjasmoro variety had the highest 100 seed weight (15.40 g), and only AT12-1035 showed the equal seed weight. The average days to maturity of 12 genotypes was 83 days. In addition to Anjasmoro variety, soybean genotypes AT12-1062 and AT12-1037 (medium maturity and medium seed size) as the new findings form this study were potential to be developed at lowland paddy fields under zero-tillage condition. The availability of the soybean genotypes adaptive to lowland paddy field under zero tillage condition is important to optimize the soybean productivity as well as the income of farmers in Indonesia.

Abstract

Climate change is likely to lead to adaptations among important crop species. Elevational gradients can be used to illustrate the effects of climate change on crop adaptation patterns. The research aimed to determine adaptation patterns in crop species across an elevational (and therefore temperature and humidity) gradient. A factorial design was applied with two factors within a simple Randomized Complete Block Design, wherein the primary factor was elevation (10 – 1,000 m). Three crop species (long bean, common bean, and winged bean) were used as test species. Growth rate and flower number were used as adaptation parameters. The results indicated that these three cash crop species showed different adaptation patterns. Common bean showed the greatest vegetative growth at approximately 600 m in elevation, long bean at 400 m in elevation, and winged bean at 10 m in elevation. The results of this study indicate that the three tested agricultural crops have different adaptation patterns, and these results was the first finding to be published in Indonesia. For agriculture practices, it can be recommended that planting of these cash crops be adapted to the elevation of the planting area.
