Abstract

Plant moss (bryoflora) is in important in the tropical forest, including Ungaran mount which is significantly play an  important role in water balance. Bryofauna can be found in moss attacking on the tree and is often referred  as moss epiphytic bryofauna. The objective of the research  were to compare the abundance and diversity of moss epiphytic bryofauna in Montana zone at three different altitudes of Ungaran mount. The sampling methods used was square plots. Bryophytes were collected in 10x10 cm plots on tree trunks. The specimens were extracted using Barlese funnel up to seven days at Laboratory of Ecology and Biosistematics, Departement of Biology, Diponegoro University. The results shows there were 5 classes of 15 ordes and 27 sub ordes/families. The highest abundance of moss epiphytic bryofauna was  in altitudes 2040 m asl (24.175 individu/m2), while the lowest was in altitude 1355 m asl (10.275 individu/m2). The biggest diversity of moss epiphytic bryofauna was found in altitude 2040 m asl (H’=2,20), while the lowest was in altitude 1355 m asl (H’=2,00). Acarina has the highest abundance in a these three altitudes. Keywords : Community Structure, Epiphytic Bryophytes, Bryofauna, Montana Zone

Abstract

Light has an important role in the avian life. Illumination can control any physiological process including reproduction and egg production because hormonal system  is regulated by the light.  One of the ways to optimize egg production is by optimizing management of lighting system including monochromatic lighting. The present study was designed to know potension of monochromatic light green, red, and blue with intensities of 5 lux for 12 hours daily  to increase weight of ovary and  number of ovary follicles in the quail. Quails divided to 4 groups and 5 repititions. The treatments were controls treatment used incandescent bulb with 5 W, second treatment used red lights with 5 W, third treatment used green lights with 5 W, fourth treatment used blue lights with 5 W. The red, green, and blue lights were provided by light emitting diodes (LED).  Parameters measured were weight of ovary, number of ovary follicles, weight of body, food consumption, and water consumption. Data was analysed with Analysis of Varian (ANOVA)  and Duncan Analysis in 95% significant.  The result showed that there are significant different in weight of ovary, weight of body, and food consumption. Monochromatic light is more effective to increase weight of ovary, weight of body, decrease food consumption than fluorescant lamp.  The Summary is monochromatic light can be used in management of lighting alternative in quail cultivation to optimyze quail production. Keywords  : Weight Of Ovary, Monochromatic Light, Number Of Ovary Follicles, Quail.

Abstract

One of heavy metal which is a source of pollution and need to be minimized its concentration on water is heavy metal cooper (Cu). In humans, chronic Cu poisoned lead to liver cirrhosis, brain damage, kidney damage and deposition of Cu in the cornea of the eye. The concentration of heavy metals in water can be remediate using microalgae, related to its biosorption potential some research on heavy metal binding ions to microalgae has been done, species Chlorella vulgaris, Phormidium sp., Dunaliella tertiolecta, Nostoc sp., Euglena gracilis has a high tolerance to heavy metal ions. The purpose of this study is to examine the effect of heavy metals Cu on populations of S. platensis and determine a decrease in the concentration of heavy metals Cu  in cultures of S. platensis, compared to the long presentation time. Research using 4 treatment concentrations of Cu  ie 0; 1; 3; and 5 mg / l with 3 replications respectively. The results showed the concentration of Cu treatment affects the population growth of S. platensis. S. platensis able to decrease the concentration of Cu in the culture medium. The larger the population of S. platensis, the greater absorption of Cu by the cell. The decrease percentage in Cu in the medium is directly proportional to the exposure time needed. S. platensis can be used as fikoremediator of heavy metal Cu at a concentration 1 mg / l of Cu.Keywords: Spirulina platensis, Fikoremediation, Biosorption, Heavy metals, Cu.
