Abstract

Mangrove is a plant that has the morphological and physiological adaptations to habitats which influenced by a tide. This plant can grow and develop in an environment of high salinity and its soil conditions are less stable and aerobic. Litter mangrove is the main source for the availability of detritus and is the largest component constituent of a food web in a mangrove ecosystem environment. Algae epiphytic microalgae is a group that lives attached to the plant, including the mangrove litter. The study aims to assess the abundance and diversity of epiphytic algae on different types of mangrove leaf litter. The observed mangroves leaf litter were Avicennia alba, Sonneratia sp. and Rhizophora sp. Epiphytic algae were brushed on mangrove leaf litter covering an area of 6.25 cm2 and diluted with distilled water. Samples were observed under a microscope with a magnification of 400 x. Water quality parameters were measured in situ and the organic ingredients, total N and P were analyzed. The results showed that epiphytic algae on each type of mangrove leaf litter were not different. Rhizophora sp is the most abundant and the richest species compared with other types of litter that are equal to 622 individuals / cm2 and 26 species of epiphytic algae. While the abundance of Avicennia alba and Sonneratia sp were 459 ind/cm2 and 321 ind /cm2, in the coastal mangrove areas of Morodemak was found 28 species of epiphytic algae. The common epiphytic algae species found in all types of mangrove litter were Cymbella sp., Coscinodiscus sp., and Synedra ulna. In general, the group of Bacillariophyta (diatoms) is the dominant species in some mangrove leaf.

Abstract

Purple yam (Dioscorea alata L.) is a traditional food as a source of alternative carbohydrates and potentially as food functional ingredients. Purple yam contains high carbohydrate and some antioxidant compounds but contains high enough Ca oxalate. This study aims to reduce the content of Ca oxalate by soaking in NaCl solution and analyze its effect on amylum size in purple yam. The research used Completely Randomized Design (CRD) with the single factor of NaCl concentration. Treatment of soaking with different concentrations of 5%, 10%, 15% and with four replications for each treatment. The parameters observed were number and size of crystal Ca oxalate (μm), Ca oxalate content (ppm) and decrease percentage, and amylum size (μm). The data were analyzed using Analysis of Variance (ANOVA) at 95% confidence level and continued by multiple-range test Duncan's Multiple Range Test (DMRT). The results showed that soaking in NaCl solution had an effect on Ca oxalate content of each treatment but did not affect on the number and size of crystals Ca-oxalate and amylum size. The best treatment was found in the treatment of P2 (10% NaCl) which can reduce Ca oxalate to 22.89% with oxalate content of 78.92 ppm. The higher concentration of NaCl in the solution increasingly affect the reduction of oxalate content on purple yam. . Keywords: Amylum, Ca oxalate, Dioscorea alata L., Purple yam.

Abstract

Kedung Ombo Lake was an artificial lake that has formed since 26 years ago. Environmental has changed from the terrestrial environment into the aquatic environment, because of that the diversity of flora around the Lake Kedung Ombo was changed. The diversity of flora can be learned through the morphology of pollen and spores. Aimed of this study was to determine the diversity of plants based on the morphology pollen and spores that found in the Lake Kedung Ombo sediment. Sampling took by coring clay soil sediment in depth of 1 m, located near the outlet of Lake Kedung Ombo. Data were analyzed by making the morphology of pollen and spores description. The result showed that morphology of pollen and spores are found in the Lake Kedung Ombo sediment has a variety of shapes and sizes. The plant's diversity obtained are 25 taxa plants that were categorized into 3 taxa of arboreal pollen (AP), 9 taxa of non-arboreal pollen (NAP) and 13 taxa of spores. The dominance of taxa NAP is Celtis sp. (45,12%), this suggested that shrubs or not plant trees were more developed in Lake Kedung Ombo environment. The study concluded that the value of diversity index categorized as low and the value of similarity index categorized as high, it means that plant diversity was quite similar and there is no significant changes of diversity with their presence were quite stable.
