Abstract

Rice eel (Monopterus albus Zuiew), have economical value is high in Banyumas, national to international markets, but rarely is grown intensively, the seed is still dependent on the catch. Reproduction of swamp eel unlike other fish species in the presence of phase teleostei  intersex / hermafroditus and in nature only spawn once a year. This study will seek to accelerate the scale seed production with natural canvas with several techniques triggers lust and sex organ maturation eels based preparedness aspects of reproductive anatomy, hormones estradiol and testosterone profiles and the intrinsic need for hormonal regulation and the mechanism for the reproductive cycle of the eel rice. In the first year aims to determine (1) the profile of estradiol and testosterone hormonal parent during the natural reproductive cycle, (2) histologic gonadogenesis (development of the testes and ovaries) eel rice during the natural reproductive cycle was evaluated by measuring fecundity. Results: In the control group, body weight gradually decreased during the study. Unlike the control group, the treatment groups were observed every two weeks showed an increase in body weight; Results of the study, in the control group (A0), the value of female eels GSI average of the first two weeks until the fourth two weeks is 0.67 % and 1.78%. While the treatment group A1 was 1.42% - 4.28% (DM-1 s / d DM-4), for the treatment A2 GSI average value is 2.52% - 7.05%; fecundity eggs increased during induction period; calibration titer two types of hormones in the first two weeks to the fourth two weeks showed improvement when compared with the control group; histological profile of rice eel gonad after induction of ovaprim-C show that up to the fourth two weeks, gonad has reached late-stage yolk globule (advanced primary oocyte), even the most mature oocyte has reached the stage: in male eels up to the fourth two weeks has reached the stage of spermatozoa

Abstract

Batik industry is one of the traditional textile industry in Indonesia which produce wastewater. Pollutants that contained in wastewater such as heavy metal and dyes. White rot fungi (Pleurotus ostreatus) from spent mushroom known can adsorb heavy metal and can decolorize dyes in wastewater. Spent mushroom have potential as an adsorbent because it still contains mycelium and cellulose. The purpose of this research is to know the difference of incubation system and volume of waste batik for  adsorption Zn and decolorization by spent mushroom of P. ostreatus and the most optimal treatment adsorb Zn and decolorize waste batik. This research used experimental methods in Completely Randomized Design (CRD) with a split plot design. The main parameters observed were the value is the level of metal Zn and absorbance of waste batik. Data were analyzed by analysis of variance (F test) then proceed with a test of Honestly Significant Difference with an error rate of 1% and 5%. The result is spent mushroom of P. ostreatus able to adsorb Zn and to decolorize waste batik. The highest Zn adsorption is J2S treatment (62,406%) that was contained 75 ml indigosol green at static incubation. The highest decolorization is J1S treatment (77,991%) that was contained 50 ml indigosol green at static incubation.

Abstract

Bee keeping of local bee (Apis cerana Fab.) in Purbalingga Regency is spread widely from  25 m to 350 m asl, eventhough quatatively the production is still low. It is caused by parasitic mite attack,  Varroa jacobsoni. This mite attack then suck haemolymph of the pupae,  meanwhile if the bee comb cell  consist of more than one mites, the pupae will die, consequently the honey production will decrease. The aims of the research are: 1) to know a mount of individual mite living and caused the death of one bee pupae, .2) to define the correlationship between density of parasitic mite and honey production, 3). To differ parasite mite V. jacobsoni  density in longitudinal and cross posision of combs.  Method used was survey with purposive random sampling tehnique on two posision of bee comb, 15 samples were taken in each posision.  The data were analyzed  by counting the amount of mite living on every dead pupae and the correlation was analyzed for the relationship between relative density of parasite mite and  honey production. The result shows that correlation between relative density of parasitic mite and honey production is unsignificant. Conclusion of the research are: 1) amount of  parasitic mite living on bee pupae and causing death is 5,80 individual on cross posisition comb and 4,71 individual on longitudinal posision comb. 2) correlation between relative density of parasitic mite and honey production is unsignificant. 3). The relative density of parasitic mite between two posisions of comb is unsignificant.

Abstract

Liquid waste of batik is dyes waste that will pollute the environment, lowers the quality of water and are toxic to living things. Spent mushroom of  Pleurotus ostreatus can be used as an alternative method decolorize of batik liquid waste. The research aimed to determine the spent mushroom of P. ostreatus ability as an absorbent of Zn and decolorize agent of batik waste, i.e: napthol, indigosol and mixed waste. This research used experimental methods in Completely Randomized Design (CRD) with 9 treatments and 3 replicates. The results showed that the spent mushroom P. ostreatus was able to decolorizing some liquid waste of batik. Optimum incubation time on the decolorization liquid waste of batik on incubation time of 72 hours.

Abstract

A study entitled "A Case Study of Plant Utilization as Traditional Medicines by Indigenous Community of Kampung Naga" has been conducted from April-July 2010. The aims of the research to determine the type, how to used and to conserve plants used for medicine by the indegenous community in Kampung Naga. The research method was survey and the data collection was done with census method, interview and questionnaire for the tribe (kuncen), midwife (paraji), community leaders and residents of Kampung Naga.  The results of the research showed that there 108 plants species including to 50 families used as medicinal plants. The organ and nutritious plants used as medicine are the roots, rhizomes, tubers, stems, seeds, flowers, fruits, and leaves, or the whole plant parts. The way to use the medicinal plants includes boiing, just posted, and immediately eaten after steaming. The plants used as medicine were obtained from the gardens, forests, yards, roadside, moor and fields. The conservation efforts undertaken by the community of Kampung Naga consist of plant planting and cultural conservation.

Abstract

Taxonomy is a branch of biology which is supported by palynological evidence. Palynology concerns to pollen and spore. The purposes of this research were to figure out plant diversity of Pliocene based on fossil pollens and to reconstruct vegetation and climates of Pliocene based on plant diversity. A survey has been conducted in Bungkanel, Purbalingga. Sampling was done for 25 sediment samples and then they were crushed, carbonate-, sulfide-, fluoride-, and organic-separated, centrifuged, oxidizing, alkali water-bathed, and mounted. Pollen and spore were identified in the laboratory with a binocular microscope. Data were analyzed descriptively, clustering, biostratigraphic Ranging-Zone, AP-NAP-Spore and PMI analysis has been done to determine the taxon, sediment age, paleo-diversity, paleo-vegetation and paleo-climate. The result showed that there were sixteen genera and three species of terrestrial palynomorph; two phyla, one class and one order of marine palynomorph. The Age of Pliocene was indicated by the appearance of Podocarpus imbricatus and Stenochlaena laurifolia (Stenochlaenidites papuanus).  The results of clustering analysis showed that there were six groups of samples with Shannon-Wienner H’ diversity index of <2. However, the palinological diagram showed that there were three local zones of vegetation-alteration. In addition, AP/NAP/Spores and PMI indicated that there were six zones of climate change.
