Abstract

The spesies composition of arthropods on agro-ecosystem can be seen as a general indicator for ecosystem stability and ecological resilience. Agricultural intensification has been linked with losses of biodiversity and disruption of key ecosystem services in farmed landscapes. This study aimed to determine how cropping system and farming systems able to increase the diversity of insects on potato field, that can be used as an integrated pest management strategy. The result showed that insect diversity index and population of natural enemies in polyculture cropping system is higher than monoculture cropping system, while the pest population is lower. Insect diversity index and population of natural enemies in organic farming systems is higher than conventional farming systems, in general the pest population was lower in conventional farming systems, but not significant with organic farming system. The polyculture cropping potatoes+cabbage+mustard+celery, potatoes+cabbage, potato+mustard respectively which grown by organic farming systems provide the highest insect diversity index, the lowest percentage of crop damage, the lowest populations of pest, and the highest natural enemy populations when compared with the same polyculture cropping with conventional farming systems. Keywords: Cropping system; farming system; insect diversity; potato

Abstract

Citrus is a major commodity in Malang. Pests attack can reduce yields of citrus. Farmers reduce pests by pesticides. The presence of pesticides would reduce biodiversity so as to cause an imbalance in the system of the chain food. It is necessary to identify the abundance and diversity of species in an orange orchard with conventional systems. The purpose of this study is to identify the structure of arthropod community and determine the stability of the environment in citrus orchards with conventional systems. This study was conducted in April 2015 - January 2016 in an orange orchard with conventional systems in Bedengan, Dau, Malang. Sampling was done in three times by the method of pitfall traps and yellow trap. Each sample has two treatments, before spraying and after spraying to determine differences in the structure of arthropod community. Results have shown that there are differences in arthropod diversity between two different places. There are some species that are dominant in each of these places. Comparison of diversity between the two places is more significant than the before and after spraying. Order of insects with the largest number of individuals is of the order Diptera 671 individuals. 440 individuals and the order Coleoptera order Hymenoptera 133. The family Formicidae before spraying has a value of 33.38 and 43.20 after spraying. And in orchard2 important value index score was 21.86 and the family Formicidae 21.91, family Culicidae 30.95 and 23.64. And in orchard2 69.52 and 24.01. family Drosopilidae 41.47 and 43.20. While in orchard2 has a value of 30.18 and 59.10. There are differences in diversity between before and after spraying spraying. Animal diversity could rise or fall depending on the behavior of each species.Keywords: Arthropods; citrus orchards with conventional systems; pitfall trap; yellow trap

Abstract

An understanding of the patterns in biodiversity is fundamentally important for efficient management of nature reserves. The objectives of this study were to: 1) investigate the diversity of understory plants in the tropical forest of Mt Pohen, Batukahu Nature Reserve, Bali, 2) explore patterns of understory plants in relation to underlying environmental factors. Field data collection was conducted to sample vegetation characteristics and the environmental parameters in the 78 quadrats of the study sites.Diversity indices (richness, diversity, and evenness) were measured and compared for each site. Environmental variables were plotted on the diagram produced by the NMDS to evaluate their relationship with the floristic patterns encountered. A total of 122 plant species were enumerated from 78 quadrats in the study area. Results show that Asteraceae and Poaceae were the predominant families in this study, followed by other most important families, i.e. Myrtaceae, Fabaceae, Moraceae, and Malvaceae. NMDS demonstrated the environmental variables most highly correlated with plant species distribution among the sites were altitude, humidity, light intensity, slope aspect and air temperature. Results also highlighted that fire and human disturbance likely play a significant role affecting biodiversity and vegetation characteristics in this forest ecosystem.Keywords: Batukahu Nature Reserve; environmental correlates; tropical forest; understorey

Abstract

This is the first publication on Zanthoxylum acanthopodium of  Indonesian germplasm based on RAPD markers. We used 7 polymorphic RAPD markers in Z. acanthopodium DC to characterize 30 accessions from three district of  North Sumatera, Indonesia. Our principal objectives are to study the genetic diversity of  the genitors. The RAPD analyse was used with 7 random primers: OPH-06, OPC-12, OPN-03, OPN-09, OPD-13, OPI-20 and OPM-01. These seven primers showed 55 bands. Further genetic diversity coefficient and the phylogenetic dendogram were developed using the Darwin 5.05 software. The Principal Coordinates Analysis (PCoA) identifies, with axes 1 and 2 explaining 39.96 % of the total molecular variation. From the analysis of genetic distance and dendogram, 30 accessions of North Sumatra’s andaliman grouped into 3 clusters. This study showed high genetic dissimilarity inter origin and intra origin.Keywords:  Genetic diversity; North Sumatera; RAPD marker; Zanthoxylum acanthopodium

Abstract

Aquatic plant has an important role in aquaculture management.  We interested in studying their salt tolerance to give guidance in choosing the right species for better management. In preliminary study we test 20 species to test their survival on different level of salinity. Collected sample were washed, weighed and placed in 100 L of different level salinity of water (5 ppt, 10 ppt, 15 ppt, 20 ppt, 25 ppt and 30 ppt). Their survival was indicated by their color and freshness of remaining biomass. Their growth rate in different salinity level was also studied for only three species, Hydrilla verticillata, Ceratophyllum demersum and Salvinia molesta, as these three species were the most tolerant to salinity change. Measurement of their growth respond to salinity change, was done by growing plant biomass in fresh water, and then gradually added with salt to increase water salinity to level of 2 ppt each week.  Results indicated that, Pistia stratiotes and Lemna minor are most tolerant to salinity. This two aquatic plant species were survives in range of salinity from 5 ppt to 15 ppt. Chaetomorpha is the most tolerant to salinity range from 0 ppt to 20 ppt. From marine alga, Gracilaria verrucosa is the most tolerant to salinity of 10 ppt to 35 ppt. In studying the growth rate, Hydrilla verticillata give the best performance in adaptation to salinity change. The species that has better adaptation to salinity change will be to be used in aquaculture management. It is recommended that, in close to fresh water, Hydrilla and Pistia will give the best candidate for aquaculture management. Chaetomorpha the best for either fresh or brackish water, while Gracilaria is recommended to be used for aquaculture management in water close to high salinity to moderate one.Keywords: Aquatic plant; Gracilaria; Hydrilla; Lemna; salt; tolerance

Abstract

Electromagnetic field (EMF) exposure has been reported produce a number of biological effects on biomolecules, cells, and up to the entire body of the organisms. Mobile phone devices, the most powerful EMF transmitters in the environment of human life, have become widely and increasingly used by the public. The exponential growth of mobile communications has been accompanied by a parallel increase in the density of EMF. Insects is one component of ecosystems that have various roles, both positive and negative, such as biological control and pests. In this study, the effect of EMF radiation emitted by mobile phone on insect over several generations were observed. Drosophila melanogaster was used as model organism and generation time, adult filial number, and sex ratio were observed in this study. As a result, a cell phone exposure significantly affected the generation time, whereas no significant effect on the adult filial number and sex ratios of D. melanogaster. Keywords: Adult filial number; Drosophila melanogaster; EMF; generation time; mobile phone; sex ratio

Abstract

Wadi is a sort of the local wisdom of Dayak ethnic at Central Borneo as the effort of food warranty when fish could be found easily or when others  sources of protein, i.e.meat is difficult to be found. Wadi is a fermentation food made from fish or meat processed traditionally by mixing the fish or the meat with salt and “lumu” (fried rice without oil),  then preserved for several days until a special aroma and taste were formed,with salty and acid taste with strong aroma. The changes of the taste and aroma of the wadi is caused by fermentation process  formed during the preservation. The effort to create the wadi as a local wisdom is need to be continued.Keywords: food warranty; local wisdom; traditional food Wadi
