ABSTRACT

Bananas, including fruit is easily damaged, one way to increase the value for bananas by processing into flour. The location is far from the plantation to processing sites causing harvested bananas should experience some time before it is processed into flour, but still can be processed into flour with good quality. This study aims to understand the interaction between the types of bananas with storage time, and to determine the type and duration of storage of bananas which have the best characteristics of banana flour. This research was conducted at the Laboratory of Plant Physiology, Laboratory of Agricultural Product Processing Laboratory and at the University Mangkurat Banjarbaru from October to December 2013.

The experimental design used was a randomized block design (RAK) while the treatment plan is a draft Petak Separated where the main plot is a type of banana (A) and the subplot was long storage (B) and repeated twice. The results showed that the interaction of bananas and storage time affects the yield and moisture content of banana flour. Banana types that characterize the best banana flour is banana kepok. Storage time which gives the best effect on the characteristics of the resulting flour banana is a banana without storage. Bananas with storage time for 3 days they could to make banana flour with good characteristics.

ABSTRACT

This research was conducted in order to know root nodule content, shape and anatomy from five species of Leguminosae trees.

Roots sample was taken from Sanga-Sanga forest area, collection forest of Mulawarman University in Lempake and other places around of Samarinda. Morphology and Anatomy of root nodules was analyzed in PUSREHUT UNMUL Laboratory of Samarinda.

The results showed that from five species of Leguminosae tree Acacia mangium Willd (Akasia), Acacia auriculiformis A. Cunn. (Akasia), Leucaena leucocephala (Lamtoro gung), Pterocarpus indicus Willd (Sono kembang) and Parkia speciosa Hassk (petai hutan), are containing nodules with varied shapes from round to elongated or oval.

Root nodules on Acacia mangium Willd and Acacia auriculiformis A. Cunn hasswelling two and three branch and sometimes four branch. The Parkia speciosa Hassk, Leucaena leucocephala and Pterocarpus indicus Willd there is no branching, root nodules light brown to dark brown, and there are up slightly blackish. Root nodule shape is round to elongated or oval.

The development of bacteria from five tree species are contained in the cells of the stele (central cylinder) root nodule. Magnification of the cell diameter plant species has a variation. Cells that are attacked by bacteria has enlarged and sizing to be 129.9% compared with those not infected on Acacia mangium Willd and 182% on Acacia auriculiformis A. Cunn., 217.9% on Leucaenaleucocephala and 180.7% on Parkia speciosa Hassk. Cell magnification stele on Pterocarpus indicus Willd difficult to determine because the entire stele cells are attacked by bacteria looksunited.

ABSTRACT

Planting kenaf plants generally use chemical fertilizers to increase production, whereas chemical fertilizers are harmful to the ecosystem environment, while a lot of agricultural waste are not utilized even wasted. Research aims for organic waste from agriculture can be utilized optimally, accompanied by the natural activator as expected with the use of fertilizers from waste agricultural lands be protected from environmental damage due to the use of harmful chemical fertilizers. The aim of research to produce a liquid organic fertilizer from various agricultural waste using natural activator and compared with standard liquid fertilizer Permentan Regulation number 70 / Permentan / SR.140 / 10 / 2011serta determine the effect of liquid organic fertilizer on the growth and yield of kenaf in East Kalimantan , This study uses two stages. The first stage of the manufacture of bio-activator to the manufacture of organic waste, then planting and growing and harvesting as well as the observation of the second stage of the manufacture of the fiber. This study did not use the controls for a comparison treatment liquid fertilizer. The observed variables include plant height, stem diameter, wet weight of leaf, stem wet weight, dry weight of leaf, stem dry weight. The data obtained were analyzed using analysis of variance (ansira) and continued with the least significant difference test (LSD) at test level 5%. Based on the results of research and discussion then be concluded that the three types of liquid fertilizer give different results is not real at all study variables and has not been able to increase the kenaf plant growth so it is advisable to increase the content of organic liquid fertilizer.

 ABSTRACT

This research was conducted in order to determine of Kenaf fiber stem quality as pulp and paper raw material. Maceration process was taken by Schultze method.

The results showed that Kenaf fiber included in quality class II (two) with average fiber length is 693.88 μm, fiber diameter is 37.66 μm and fiber wall thickness is 2.63 μm. The conclusion of Kenaf stem has short fibers, fiber diameter is large and thin wall fiber.

ABSTRACT
Fungi are organisms lacking chlorophyll, fungi can not perform photosynthesis just like plants, so it can not utilize the sun's energy directly. The fungus gets food in the form so as cellulose, glucose, lignin, protein and starch compounds. Fungus that grows in the tropical rain forest most of which are wild mushrooms and dekomposisi degrading living foliage forest floor. This research was conducted in the campus environment to identify the type of fungus and nutrient content of the fungus. The fungus showed water content 75.77% (B o n d a r z e w i a  b e r k e l y i ) and 81.45% (G a n o d e r m a s p ) , 79.02% (Volvariella volvacea L.) and 89.52% (Pleorotus ostreatus), fiber 11.54% (B o n d a r z e w i a  b e r k e l y i ) and 3.8% ( G a n o d e r m a s p ) , 4.33% (Pleorotus ostreatus)  and 3.48% (Volvariella volvacea L.), Fat 3.8%  (B o n d a r z e w i a  b e r k e l y i ) dan 1.61% (G a n o d e r m a  s p ) , 0.20% (Pleorotus ostreatus)  and 1.95% (Volvariella  volvacea L.), Protein 1.70%  (B o n d a r z e w i a b e r k e l y i  dan   1.72% (G a n o d e r m a s p ) , 2.83% (Pleorotus ostreatus)  and  1.34% (Volvariella volvacea L.). karbohidrate 14.77%  (B o n d a r z e w i a b e r k e l y i  and   13.01% (G a n o d e r m a s p ) , 12.68% (Pleorotus ostreatus)  and  4.68% (Volvariella volvacea L.).
