Abstract

Aedes aegypti is a major vector of Dengue Fever (DHF) that is spread through mosquito bites. However, Bandar Lampung ranked 3rd out of 15 districts in Lampung Province with an IR (Incidence Rate) of 59.43. One way to reduce dengue cases is vector control. Temefos is commonly used as a chemical vector's control and it is possible can cause resistance to larvae. The information about Aedes Aegypty has not been widely known about larval of Aedes aegypty's susceptibility towards Temefos in Lampung Province. Therefore, this study aims to determine the susceptibility status of Aedes aegypti larvae towards Temefos in Way Kandis Village, Tanjung Senang Regency, Bandar Lampung. This research was conducted in December 2018 - February 2019. This study uses five different temefos concentrations, i.e ;0 mg / L concentration as control, 0.005 mg / L, 0.01 mg / L, 0.02 mg / L, and 0 , Each 03 mg / L was repeated in 4 times. Observations were made by calculating the number of larvae that fainted, died, and lived. The results show that the susceptibility of Aedes aegypti towards Temefos in Way Kandis Village, Tanjung Senang Regency, Bandar Lampung City, is categorized as susceptible in the concentration range of 0.005 - 0.03 mg / L.

Abstract

Recycling metal scrap is an effort to save The earth from pollution, meanwhile in the process of recycling metal scrap usually it took a lot of water in the process to cooling it from such a high temperature. The purpose of this study was to identified water quality from the water in the reservoir and the water quality of the river that indicated receiving overflow from reservoir water when in the rainy season. The study was conducted from October to November 2020 at the Melting Scrap Factory and the river around the industrial zone. The study was conducted by taking a water sample for analysis in the spot (in-situ) and in the laboratory (ex-situ). The water sample was taken by a field technician laboratory. The result from laboratory analysis counted to indicate the water quality using Pollution Index methods (PI).and then in order to detect pollution from the fish that lived inside the pond using nutrition value coefficient (NVC). After the analysis data was counted the result showed that the water-saving pond had 3,20 values for pollution index(PI) and the river had 3,71 values for pollution index(PI), both of the results indicated that status water quality was classified as lightly polluted if it referred to the policy KEPMEN LH NO 11 Tahun 2003 for standard water quality class 3. Based on the data that has been counted for NVC the result was 1,84, it showed that the fish could live healthily but for further analysis laboratory on the fish meat, it showed that the fish meat was contained a high amount of a heavy metal compound such as iron (Fe) which had value over the standard (1953 mg/kg), from that value it showed how polluted the fishes in the reservoir. The fish should not be eaten by humans because of the high amount of heavy metal compound

Abstract

Purple cabbage plants require an adequate supply of water in the process of growing. So that if there is a lack of water it can result in stressful conditions then the growth of purple cabbage is disrupted and can even cause death. The purpose of this study was to determine the tolerance limits of purple cabbage to PEG 6000, and to determine the effect of PEG 6000 on the growth of purple cabbage as a simulation of drought stress. This research was conducted using a completely randomized design with the main factor being PEG 6000 with 5 concentration levels: 0 % w/v, 10% w/v, 20% w/v, 30% w/v and 40% w/v with 5 replications. As parameters are plant height, length, width, and number of leaves, also chlorophyll content. Then analyzed with the Levene test, one way ANOVA and the Tukey HSD test at 5% level. Based on the results of the research, it can be concluded that giving PEG 6000 shows that the tolerance limit for purple cabbage plants to PEG 6000 treatment is at a concentration of 10%, then giving PEG 6000 gives a negative response to the growth of purple cabbage which is indicated by a decrease in plant height, leaf length, leaf width, number of leaf, also chlorophyll a, b, and total chlorophyll content.

Abstract

The research was conducted in a factorial experiment with factor A: far-red light treatment with 2 levels: control (without far-red light), and treatment (far-red light). Factor B was a time of observation with 3 levels: 4, 6, 8 days after wrapping. Wrapping each detached fruit in a combination of four layers of blue-colored plastic, one layer of green-colored plastic, and two layers of red-colored plastic resulted in a red light treatment. Transmission measurement of that plastic combined with a spectrophotometer at wavelength 700-735 nm was 75%. To deter fresh weight, each fruit was weighted with an analytical balance. Total soluble carbohydrate content was determined by the phenol-sulfuric method and counted based on the glucose standard curve (mg/gram tissue). Analysis of variance was conducted at a 5% significant level, and if the interaction was significant, then continued with simple effect determination at a 5% significant level by the F test. The fresh weight average of the soluble carbohydrate content of treated fruits was higher than the control. The fresh weight of chili fruits was relatively constant during observation of both treated and controlled fruits. The total soluble carbohydrate content average relatively did not differ between treated and control fruits. Total soluble carbohydrate content was increased 6 days after treatment and decreased 8 days after treatment. The result of this research concluded that red light inhibited the ripening process of chili fruits by slowing the decrease of fresh weight.

Abstract

Bamboo is a type of plant that grows in Indonesia. So far, people only use the stems and throw away the leaves. As a result, these abundant bamboo leaves become waste. Bamboo leaf waste contains lignin content of 19.8-26.6%, and becomes compost in the long term. The process of composting bamboo leaf litter can be accelerated using an activator such as the inoculum fungi Geotrichum sp. which is ligninolytic so that it can break down lignin complex compounds contained in bamboo leaf waste into simpler compounds. Sorghum contains about 6.5-7.9% fiber. The high fiber content in sorghum seeds can be used as a growth medium for fungal inoculum. The purpose of this study was to determine the effect of sorghum as an inoculum medium for Geotrichum sp. and the effect of inoculum on compost quality. This research was carried out in August - December 2019 at the Microbiology Laboratory of the Biology Department, Faculty of Mathematics and Natural Sciences, Unila. This study used a completely randomized design (CRD) method with 4 treatments, namely Control (Bamboo leaf litter), P1 (Bamboo leaf litter + 1% inoculum), P2 (Bamboo leaf litter + 1.5 % inoculum) and P3 (Bamboo leaf litter). + 2% inoculum) each treatment was repeated 3 times. The variables observed were the number of spores and spore viability using the Colony Forming Unit (CFU) calculation on inoculum and compost. Analysis of the content of C, N, P, and C/N ratio was carried out to determine the quality of the compost. Based on the research results, sorghum can be used as a growth medium for the ligninolytic fungi inoculum Geotrichum sp. with spore viability of 74.18% and the addition of 1.5% inoculum (P2) gave the best results on the quality of bamboo leaf compost (Bambusa sp.)
