Starch Production

Sago (Metroxylon spp.) is the world’s highest starch producer that have high productivity. Sago starch, however, is still underutilized compared to other starch. Sago can produce dry starch of 20-40 ton per ha per year. Indonesia has the largest sago area in the world with more than 90% of the world’s total sago area. Sago have high species diversity and not all of them have the same starch-producing capability. This research was conducted to gather information on the morphological characters and starch production potentials of several types of sago in Meranti Islands Regency, Riau Province, Indonesia, especially in Bandul, Mengkirau, Tanjung Peranap, and Bagan Melibur. Three different types of sago in Kepulauan Meranti Regency, Riau, has been identified, namely Beremban, Meranti and Sangka. The morphology and starch production of different types of sago vary depending on environmental conditions, including soil types. Beremban Sago collected from Bandul Village were found to have the highest starch content, therefore it has potentials to be developed for starch production in Indonesia.

Nematodes are microscopic worms belonging to the soil biota with high species diversity. Nematodes have different compositions in different types of soil and areas. This research is conduct to determine the presence and genus of soil nematodes found in mustard plantations in Landasan Ulin Utara Village, Banjarbaru, South Kalimantan. Soil samples are taken from community vegetable plantations with a depth of 0-20 cm around the mustard plant rhizosphere located in ??Jalan Kurnia and Jalan Sukamara, Landasan Ulin Utara Village, Banjarbaru. Extraction to separate nematodes from soil using the Whitehead & Hemming method (1965) and nematode fixation using the Seinhorst method (1959). Furthermore, the permanent nematode preparations were made for the identification stage by morphological observations and morphometric measurements. The identification results showed that the genera of nematodes found in the study site's soil samples were Iotonchus, Crustorhabditis, Ironus, and Xiphinema.

This study aims to determine the utilization of sago starch production on sago processed products at 5 times the potential of sago in merauke district. Data were analyzed descriptively, the population in this study were 5 districts with high productivity of sago farming in Merauke district, namely land sloping districts, curates, eligobel, ulilin and muting. Site selection by purposive sampling or deliberately. The results of the study showed that the five districts were not optimal for developing processed sago products due to lack of knowledge, expertise and limitations of technology adoption.   Keywords: Local Farmers, Productivity, Optimization, Sago

Wetlands in natural areas in South Africa have been described before, but no literature exists concerning the phyto­sociology of urban wetlands. The objective of this study was to conduct a complete vegetation analysis of the wetlands in the Potchefstroom Municipal Area. Using a numerical classification technique (TWINSPAN) as a first approximation, the classification was refined by using Braun-Blanquet procedures. The result is a phytosociological table from which a number of unique plant communities are recognised. These urban wetlands are characterised by a high species diversity, which is unusual for wetlands. Reasons for the high species diversity could be the different types of disturbances occurring in this area. Results of this study can be used to construact more sensible management practises for these wetlands.

The genusArthriniumincludes important plant pathogens, endophytes and saprobes with a wide host range and geographic distribution. In this paper, 74Arthriniumstrains isolated from various substrates such as bamboo leaves, tea plants, soil and air from karst caves in China were examined using a multi-locus phylogeny based on a combined dataset of ITS rDNA, TEF1 and TUB2, in conjunction with morphological characters, host association and ecological distribution. Eight new species were described based on their distinct phylogenetic relationships and morphological characters. Our results indicated a high species diversity ofArthriniumwith wide host ranges, amongst which, Poaceae and Cyperaceae were the major host plant families ofArthriniumspecies.

The Atlantic Rainforest has high species diversity and endemism and is one of the most threatened ecosystems in the world. However, the rainforest understory stratum is regarded as the least studied and understood with regards to biodiversity. The aim of our study was to develop an up-to-date checklist of flowering plants collected in 10 Atlantic Rainforest remnants in Southern Bahia, Brazil. The floristic inventory recorded 49 families, 103 genera, and 170 species. The richest families were Rubiaceae (34 spp.), Melastomataceae (16), Bromeliaceae, Poaceae (8 spp.), Cyperaceae, Erythroxylaceae, Marantaceae, Myrtaceae, and Piperaceae (7). We record 10 new state records for Bahia and two new taxonomic novelties (Bertolonia sp. nov. and Palicourea sp. nov.) were discovered. The species composition is very exclusive with 85% of species occurring in only one of the studied areas and 27% being endemic to this biome region.

Kalimantan Island is rich in genetic resources and species diversity of Durio spp. Of the 27 durian species in the world, 18 species are found in Borneo. The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. Two of the best-known edible durians in East Kalimantan are Durian (Duriozibethinus) and Lai (Durio kutejensis). However, as a plant with a cross-pollination mechanism, there are many results of natural crosses between the two. The study aimed to identify Durian x Lai plants in Loa Kulu, Kutai Kertanegara, East Kalimantan Province, Indonesia as the superior local fruit crops potentially agribusiness industry. This research was carried out by collecting data and information about the morphological characteristics of the plants and fruits from D. Zibenthinus x D. Kutejensis. The results of the study successfully identified 6 potentially superior plants that are believed to be the result of a cross between D. Zibenthinus x D. kutenjensis. The 6 potential superior plants were found to have different morphological characters. This is the initial identification and being a basis of the next research phase, which is to identify the morphology of trees, flowers, and fruit to obtain new cultivars crossing D.zibenthinus and D. Kutejensis which have superior potential as superior commodities from East Kalimantan.

The majority of the species of Kalanchoe Adanson (1763: 248) in cultivation in, especially, mild-climate parts of the world originates from Madagascar, a present-day centre of high species diversity for the genus (Gehrig et al. 2001; Descoings 2003; Smith & Figueiredo 2018). Of 45 species, hybrids, and cultivars of Kalanchoe listed by Springate (1995: 178–185) as being cultivated in Europe, both out-of-doors and under glass, 29 (~64%) are either from Madagascar or are based on material originally collected from that country, with the remaining 16 being mainly from eastern and southern Africa, as well as from the Middle East, Socotra, India, and east Asia.

Dengue fever is a painful mosquito-borne infection caused by different types of virus in various localities of the world. There is no particular medicine or vaccine to treat person suffering from dengue fever. Dengue viruses are transmitted by the bite of female Aedes (Ae) mosquitoes. Dengue fever viruses are mainly transmitted by Aedes which can be active in tropical or subtropical climates. Aedes Aegypti is the key step to avoid infection transmission to save millions of people in all over the world. This paper provides a standard guideline in the planning of dengue prevention and control measures. At the same time gives the priorities including clinical management and hospitalized dengue patients have to address essentially.
