Abstract, Urban Forest is one of the Public Green Open Space which is controlling atmosfer, water, and soil pollution. Carbon dioxide (CO2) is one of the emission substances of greenhouse gas sources. Increased concentration of CO2, which comes from burning fuel oil and gas, can cause various diseases, such as upper respiratory tract infections, heart disease, cancer and etc. Therefore, it is necessary to reduce CO2 emissions, which one of them is through the utilization of Public Green Open Space, especially urban forest. Jambi City as the most populous area in Jambi Province has high CO2 emission potential. The purpose of this research is to predict the potential of tree vegetation in urban forest in Jambi City in reducing CO2 gas. The research was conducted in 3 locations: Bagan Pete Urban Forest, Muhammad Sabki Urban Forest, and Pine Forest Kenali. The vegetation analysis was performed using the Quadrant Method, where the 10 x 10 m observation plot was determined randomly. Vegetation analysis at each location was conducted to obtain basal area, which then determined the potential of CO2 emission reduction. The basal area of the trees vegetation at each location was 72,72 m2/Ha, 25,45 m2/Ha and 5,12 m2/Ha. Reduction of CO2 of tree vegetation in urban forest in each location in sequence was 41386 Ton/Ha/Year, 14482.93 Ton/Ha/Year, 2916.94 Tons/Ha/Year. Bagan Pete Urban Forest has the highest reduction potential. Based on this research, total carbon dioxide emission reduction potential through urban forest in Jambi City was 58785,87 Ton/Ha/Year.

Abstract Infectious male Aedes aegypti mosquitoes can transmit dengue virus (DENV) to transvenereal non-infectious female mosquitoes. Infectious female mosquitoes will reduce DENV to the egg stage and propagate to the adult mosquito stage. Egg stage is a stage of viability / resistance of Dengue Hemorrhagic Fever (DHF) vector. The study aims to determine the effect of transvenereal transmission on egg viability resulting from parental Ae. aegyptifemale mosquitoe with DENV-3 infection, with variations in egg storage time. This type of experimental research with purposive sampling. Egg samples were obtained from the Ae. aegypti female parental mosquito detected positive DENV-3 by PCR testing. Egg samples were stored for 14, 30, 60 and 120 days. Analysis to determine differences in viability in eggs derived from infectious female mosquitoes compared to controls using an independent T-test. Analysis to determine the viability of eggs derived from parental infectious female mosquitoes based on variations in storage time using ANOVA. The results of the study stated that there was no significant difference (P = 0.794) between the average eggs that succeeded in becoming imago (viable eggs) derived from parental infectious female mosquitoes compared to controls. The analysis also stated that there was no significant difference (P = 0.18) between the average viable eggs derived from parental infectious female mosquitoes both storage duration for 14, 30, 60, or 90 days. Keywords: Aedes aegypti, dengue serotype 3, storage time, transvenereal transmission, egg viability.

Abstract. This study aims to determine the diversity of zooplankton in Lake Sipin. This study uses a descriptive exploratory method by determining the location by purposive sampling. The results showed that found 6 zooplankton classes, namely: Tubulinea, Monogononta, Maxillopoda, Euglenophyceae, Imbricatea, and Eurotatoria consisting of 15 types, namely: Arcella sp., Difflugia globulosa, Difflugia limnetica, Difflugia pyriformis, Asplanchna sp., Brachionus sp., Cyclopoid sp., Macrocyclops varians, Trachelomonas rachiborskii, Euglypa cristata, Polyartha trigla, Trichocerca sp., Trichocerca birostris, Trichocerca bicristata. Abundance ranges from 0.0031 Ind / L - 0.0051 Ind / L; Evenness index ranges from 0.876 - 0.915; diversity index 1.41 - 2.164; and a dominance index of 0.128 - 0.292. Diversity is classified as moderate because the diversity index obtained is greater than 1 and smaller than 3 and no species dominates. It can be concluded that the highest diversity is found in the Tubulinea class. Lake water quality can be tolerated by zooplankton because it tends to have good value. Researchers are advised to conduct research at night to see the relationship between the distribution of zooplankton with the intensity of sunlight, as well as conducting research by determining the location of more diffuse points.
