Abstract

Reproduction of Endemic Fish Butini (Glossogobius matanensis) Based on Depth and Time in Towuti Lake. Butini fish (Glossogobius matanensis) belonging to the Gobiidae family and is one ofendemic fish in Towuti Lake and classified as demersal fish. Fishing activities and habitat quality changes tend to reduce butini stocks in Towuti Lake. Therefore, it needs to be protected of stocksfor sustainability. This research is to determine reproduction of endemic fish based on depth and time as basic data for the effort of conservation and domestication. Gonad maturity that was analyzed histologically obtained five maturity stages. Based on the diversity of egg size, especially in the gonad maturity stage (IV), it is indicated that butini fish are classified as partial spawner. Male and female fish gonad mature (50%) at 36.22 and 31.43 cm total length, respectively. October and March, an estimated spawning peak of butini fish in Towuti Lake held this month at a depth of 150m and 200 m. Fecundity of butini fish in gonad maturity stage (III and IV) between 11184-66305 eggs and 14922-81522 eggs, respectively. The highest mean of fecundity there in October (56,907 eggs) and the lowest was found in July (25,447 eggs). Fecundity of fish at 25 m-200 m depths ranging from 30.778-35.329 eggs.Keywords: Reproduction, endemic fish, Glossogobius matanensis, depth and time, Towuti Lake

Abstract

ABSTRACTCharacterisation of Organic Carbon of Up Stream Citarum River Water from Domestic andIndustrial Waste Effluent. The local government of Citarum upstream area has conducted theriver cleaning program to increase Disolved Oxygen since 1991 until now. The program hasimpacted to installments of to wastewater treatment for 80% industrials in the Upper Citarumdrainage area declining the load of BOD5 wastewater. However most of waste water comingfrom Banung population have been treated in the collective wastewater treatment (IPAL) ofBojongsoang. Nevertheless, the low concentration of Dissolved oxygen which is under theminimum stream standard concentration, 3mg/l still becomes a problem until now. Anineffectiveness of improvement of the DO is caused by the treatment effluent BOD5 load fromdomestic and industrial wastewater and low awareness industrial wastewater aboutcharacteristics of river water quality . This research aimed to characterize the BOD oxidationrate and BOD5 regime of each river reach base on wastewater domestic or industrial characteristic.The result of this research can then be applied to build the priority of the load reduction ofBOD5 wastewater domestic or industrial in each reach of that river. The characteristic ofoxidation rate have investigated at influent point and water body of Upper Citarum River bymultivariate cluster observation. The oxidation rate was calculated by least-square methodfrom BOD data. The BOD observation was measured by BOD meter everyday for 5 days. Theresult shows that Curugjompong at 0 to 21st km and 36th km to Majalaya bridge ischaracterizedby an industrial sewage, while the upper Citarum at 21 to 36 Km is characterizedby an domesticsewage.Key words: Characteristic, oxydation rate, Citarum river, organic carbon.

Abstract

Superior upland rice cultivar can be assembled through crossbreeding using germplasm diversity which serves as a sourceof gene. Germplasm may constitute of landrace and local cultivars. Banten is one of the provinces that has various localupland rice varieties. Baduy tribe, in the province has played a major role in preserving local upland rice varieties anduphold the wisdom.Genetic diversity information and the benefits of local cultivars can be useful to maximize the selectionprocess of parental candidate for creating new cultivars. This study aims to determine the genetic diversity of local uplandrice from Banten. Methods of analysis diversity performed by phenotypic and genotypic. Observations phenotypic throughobservation of agronomic characters and yield of each cultivar. Whereas genotypic observations conducted with RAPD(random amplified polymorphism DNA). In this study we used 17 local upland rice cultivars from Banten with 14 randomprimers for RAPD. The result showed a mean plant height local upland rice cultivar of Banten was higher than nationalupland rice varieties however productive tillers and rice productivity were lower than national varieties. Nonetheless, localcultivars persisted in this environment because it has the advantage that the community needed. Based on the time ofharvest, local cultivar belonged to early and medium maturing group. Qualitative trait observation showed that there werediversity of stem, leaves, grain and rice among the cultivars. Genetic analysis with RAPD showed nine primers out of 14were successful in amplifying loci from DNA template. The primers having high amplification product were OPJ 05, OPJ07 and OPD07 but the highest polymorphism presentation was OPJ 01. Based on phylogenetic tree, there were two mainclusters. Padi Koneng and Carogol were similar. Three glutinous rice cultivars (Mayang, Jalupang, and Hideung) were inone cluster except Kentan Simpai.Keywords: upland rice, Banten, RAPD, Phenotipe, genotype

Abstract

ABSTRACTSomatic cell manipulation of Artemisia annua L. was conducted by induction of polyploid plants with Colchicine and Oryzalin in order to increase level of artemisinin. Polyploid plantlets were multiplied on MS medium without plant growth regulators. After acclimation processes, plants were grown in the field for agronomic performance observation. Survival rate of plantlets was recorded. Agronomic performance of plants was observed by recording height of plants, number of branches, leaf biomass, stomatal characteristics, and artemisinin content. The results showed that survival rate of the plantlets from Colchicine and Oryzalin treatments were ranging from 13.40 to 33.33% and 11.11 to 41.67%, respectively. Growth rates of plant height and plant branching were not significantly different between diploid and tetraploid plant both from Colchicine and Oryzalin treatments, except to triploid plants from Colchicine treatment. Averages of plant height from Colchicine and Oryzalin treatments were ranging from 10.0 to 220.0 cm and from 35.0 to 186.0 cm, respectively. The averages number of branches per plant of polyploid plants from Colchicine and Oryzalin treatments were ranging from 3 to 66 and from 11 to 63, respectively. Averages of dry leaves biomass between diploid and tetraploid plant from Colchicine and Oryzalin treatments were also not significantly different. They were ranging from 12 to 64 g/plant and from 11 to 62 g/plant, respectively. However, tetraploid clones have bigger size of stomata and produced more artemisinin than the diploids.Keywords: Artemisia annua L, Colchicine, Oryzalin, Polyploids, Acclimation, Agronomic performance
