Abstract

Dragonflies have an important role for the stability of the ecosystem that is as predator and prey at the same time. The availability of food resources and optimal environmental conditions affect the species richness of dragonflies in the habitats. Reasearch on dragonfly comunity structure aims to find out the differences of community structure in each habitat type in the region of Curug Lawe Benowo. The research was conductet in 4 different stations which focus on species of dragonfly, amount of an individual species, habitats, environmental conditions, and the corellation between the variables. The method used is point count. The results showed that there are 19 dragonfly species which came from 7 different Family. The total number of individuals encountered from 4 stations is 205. The common species that can be found in all of the stations is Euphaea variegata. The level of diversity are medium, the level of evenness is fairly even. Similarity of species in any habitat types indicate that the habitats has a three kind of similarity levels that is fairly equal, less equal and not equal. Data analysis shows that there is a corellations between environmental conditions, and dragonfly species, affecting abundance and distributions of a dragonfly in the habitats, and can be used to describe dragonflies community structure in the region. Key words: Community structure, dragonfly, Curug Lawe-Benowo

Abstract

Jamur ling zhi (Ganoderma lucidum) sudah mulai dibudidayakan secara intensif di Indonesia. Masalah yang sering dihadapi dalam budidaya jamur ling zhi adalah kesulitan dalam penyediaan bibit. Proses penyediaan bibit jamur biasanya dilakukan secara konvensional menggunakan media agar. Metode konvensional akan membutuhkan biaya dan waktu produksi yang banyak sehingga diperlukan metode pembibitan baru yaitu kultur terendam teragitasi. Kultur terendam miselium dari kultur murni langsung dapat ditanam pada media tanam jamur. Penelitian ini bertujuan untuk mengetahui perbandingan produksi miselium jamur ling zhi dalam medium air kelapa tua dan tauge extract broth dengan metode terendam teragitasi. Parameter  utama penelitian meliputi berat kering miselium, sedangkan parameter pendukung meliputi suhu inkubasi, pH medium awal dan akhir inkubasi. Penelitian dilakukan dengan rancangan acak lengkap faktorial (RAL) dengan faktor medium. Hasil penelitian menunjukkan bahwa produksi miselium jamur ling zhi (G. Lucidum) dalam medium air kelapa tua lebih tinggi dibandingkan medium tauge extact broth. Kata kunci: Ganoderma lucidum, Medium, Air Kelapa Tua, Tauge Extract Broth, Kultur Terendam Teragitasi

Abstract

Drought stress will result in decreasing the rate of water absorption by plant roots. This decrease will result indisturbances in plant growth, especially in a growing network includes the addition of Growth in dry mass, volume,length or area of cells resulting from the interaction of processes in plants through photosynthesis, respiration,transport, water relations and nutrient balance. Morphological and physiological responses of plants against stressand patterns of plant adaptation to different environments is very important especially for the purposes of cultivationand the prediction of the properties of responsive plant tersebut. Purpose of this research is to examine changes incontent klorofil a and b, and growth (number of leaves and plant height ) cocoa seedling age of 12 months atdifferent water stress.The study was conducted in the village of Plana Banyumas, Central Java Province, which lasted from January2007 to June 2008. Cacao tree used was 12 months in which the cocoa beans used for seeding of hybrid clonesderived from cocoa pods from the village of O, o Kulawi Donggala District of Central Sulawesi. Cocoa seedlingswere given three treatments of water stress that soil water content 75%, 50% and 25%. Observations of variablechlorophyll a and b,number of leaves and plant height after one month and two months of stress.The results showed drought effect on leaf chlorophyll content of seedlings of cocoa, where the plants grown on soilwater content of 50% have chlorophyll a and b are lower than those grown on soil water content 75%. The growth ofcocoa seedlings are best when planted with soil water content 75%, because the soil moisture content of 50% and25% of the number of leaves and plant height decreased

Abstract

Aedes aegypti mosquito is a vector of dengue hemorrhagic fever (DHF). One place that is endemic by A.aegypti mosquitoes is the city of Semarang, specifically  in Tembalang District. Tembalang district is one of the areas with highest DHF incidence rate. A.aegypti mosquito vector control is still using artificial insecticide, where the insecticide has negative impact to health and environment. Zodia leaves (Evodia suaveolens) are known to have potential as a natural insecticide, because they have secondary metabolites such as tannins, alkaloids, flavonoids that can be used as biolarvasides. This study aims to determine the content of phytochemical compounds of zodia leaves extract and to know the mortality in each population to zodia leaves extract. The extract of zodia leaf is obtained using maceration method. Chemical compounds contained in zodia leaves were analyzed using FT-IR. This research method is bioassay test, where the larvae are soaked with various series of concentration of zodia leaf extract. Each series of concentrations required ten larvae. The larvae used came from five kelurahan in Tembalang Subdistrict. The data were processed using probit analysis to obtain LC50. The results of LC50 obtained from the smallest to largest is 39,94 (34,67-45,28); 41,98 (36,6-48,07); 46,18 (39,28- 53,97); 47,62 (39,92-54,32) and 49,44 (42,24-58,25). The result of LC50 shows that is not significantly different, because there is the value of the overlapping fiducial limits between each population

Abstract

Late blight disease caused by Phytophthora infestans, is probably the single most important disease of potatoes worldwide. Infected plants were quickly killed and were difficult for replanting, causing significant losses for the growers. Various control methods were examined including the use of biocontrol agents of PGPR.  The research objective was to determine the ability of PGPR product from Ngudi Makmur farmer group local to delay late blight disease incidence on potato plants in the field. The in vivo experiment was carried out at potato land area located at Kledung  Sub District, Kledung District and Temanggung Regency. Randomized Block Design (RBD) with five treatments was applied with five treatments each of which was placed in a different plot and each plot was filled with 40 plant treatments. On the first plot, no treatment was given (P1); the second plot was given chemical fertilizer (P2), the third plot was supplemented with PGPR one dose (P3), the fourth plot was PGPR two dose (P4), and the last was the fifth plot treated with GA hormone (P5). Result of the research showed that application of PGPR could delay disease intensity until 14 days. These antagonist could be used as biological agents initials to control leaf blight disease. There was an improvement in the quality of potato tubers harvested with the PGPR application compared to controls too.

Abstract

Local duck had been widely cultivated not only as a producer of eggs processed as salted egg but also there are cultivated as broiler ducks. The efforts to improve the productivity of ducks can be seen from the effectiveness of the process of absorption of nutrients in the duodenum, so the use of energy in the metabolic process can be optimized for adding mass and volume of the cell.  This study aims to determine the duodenum profile of the histological structure  covered the lumen diameter, villous height and number of goblet cells of Magelang ducks, Tegal ducks and Pengging ducks .This study used a completely randomized design (CRD) with three treatments (Magelang ducks, Tegal ducks and Pengging ducks) and 6 replications. The measured variable was the long intestine tenue, lumen diameter, villous height and number of goblet cells. Data were analyzed using analysis of variance (ANOVA) with a differentiation factor was the type of duck. The realdifferences data were analyzed using advanced test of Duncan at the level of 95%. The results showed long intestine tenue, lumen diameter and height of the villi were not significantly different at each Magelang ducks, Tegal ducks, Pengging ducks. The number of goblet cells in Magelang ducks and Tegal ducks showed significantly different, but not on Pengging Ducks. The conclusion of the study was the length of the intestine tenue, lumen diameter and height of villous had no real effect on three types of ducks. Keywords: Local ducks, duodenum, histological
