Uptake Test the Content of Ambient SO<sub>2 </sub>(Sulphur Dioxide) and NO<sub>2</sub> (Nitrogen Dioxide) Compounds in Lichen Thalli in Urban, Sub Urban and Forest in Surakarta, Central Java, Indonesia

Lichen or commonly known as symbiotic organism lies between fungi and algae. It is a non vascular simple organism and it is very sensitive to environmental conditions. The research method used was an exploration. It was then continued with the analysis of the pollutant uptake test by a spectrophotometer. To determine the sampling point, the purposive sampling technique was used. The study was divided into 3 main areas based on the environmental differences, namely urban, suburban and forest. There were about 30 trees sticked by corticolous lichens. The pollutant parameters measured were SO2 (sulfur dioxide) and NO2 (nitrogen dioxide). The air quality data were the secondary data such as NO2 and SO2 ambient air that issued by the Environmental Services (DLH) of Surakarta Government Central Java Indonesia. The range of NO2 ambient content in the research locations, namely in the city of Surakarta and the suburban of Jaten Karanganyar was still below the Ambient Air Quality Standards (ABML) issued by the Government, which ranged from 4.29 - 49.72 μg / Nm3.3. The Quality Standard values for ambient NO2 were 316 and μg / Nm3. At the same time, the ambient SO2 values ranged from 0.153 to 36.74 μg / Nm3, still below the threshold of Ambient Air Quality Standards for SO2 issued by the Government on 632 μg / Nm3. The values for SO2 content in the lichen thalli ranged from 0.17 to 4.05 and it was from 0.773 to 4.03 for the NO2 content. The SO2 and NO2 content values in the lichen thalus found in lichens that grow in urban areas are the highest than in urban and forest suburbs. There is a content of pollutant compounds that are identical between thalus lichen and pollutants in the atmosphere (ambient air) so that lichen thalus is able to absorb pollutant compounds in the atmosphere which can be characterized by the morphological characters of thalli that live in urban, suburban and forests. We will be able to publish your paper in electronic form on our web page http://www.scientific.net if the paper format and the margins are correct. Your manuscript will be reduced by approximately 20% by the publisher. Please keep this in mind when designing your figures and tables, etc.</jats:p

Pelatihan Pembuatan Blog Pembelajaran Bagi Guru Sekolah Dasar Punna Karya Kabupaten Tangerang

The aim of community service is to provide blogging skills that can be utilized by Punna Karya Tangerang elementary school teachers in learning. The service delivery method is a workshop held from November to December 2019. Evaluation of activities is carried out using non-test techniques using questionnaires and documentation. The questionnaire was used to compare teachers' understanding of creating learning blogs between before and after the training was carried out. While the documentation serves to see qualitatively a learning blog created by the teacher. The results of this community service are: (1) classically the competence of teachers in creating learning blogs increased by 85,80%; (2) qualitatively the learning blog produced by the teacher is good, but there are still shortcomings in terms of interface design, navigation, and its contents. Based on these results teachers should be able to improve their skills independently in designing blog-based learning media through online and print references.</jats:p

TEST OF THE EFFECTIVENESS ANTIHIPERGLIKEMIA OF COMBINATION CUCUMBER JUICE(Cucumis sativus) AND TOMATO (Solanum lycopersicum L) ON THE WISTAR MALE RAT

Diabetes mellitus is a metabolic disease with characteristics of hyperglycemia. Conventional treatments using oral medications such as glibenclamide and metformin have many side effects. Therefore, it is necessary to find an alternative drug that is more effective and safer. Some agents that are often used as anantihiperglikemia are cucumber and tomato.The purpose of this study was to determine the effectiveness of combination of cucumber and tomato juice to decrease blood glucose levels of male Wistar ratsusingglucose tolerance method. Male Wistar rats were fasted for 10 hours and then measured the levels of fasting blood glucose. Then animals test were given the juice (single and combination), 30 minutes later were given a dose of sucrose load of 6.75 g / KgBW orally. Blood glucose levels of animal testre-measured at 30th, 60th, 90th, and 120th minutes after loading sucrose using a glucometer.The measurement results showed that blood glucose levels of the combination of cucumber and tomato juice group with dose ratio of 28 g/KgBW:16.8 g/KgBW gave decrease blood glucose levels significantly compared to the negative control group (p≤0.05) and didn’t not provide a significant difference compared to the metformin group (p ≥0.05).</jats:p

The Effect of Change in Function from Paddy Field to Dry Land on Soil Fertility Index

This research studied the effect of the change in function from paddy field to dry land on the soil fertility index. The research was conducted in Girimarto Sub-district, Wonogiri District, in the Province of Central Java. The five stages of the research were: determination of Land Mapping Units in areas with a change in land use; field survey; laboratory analysis; determination of Minimum Data Sets (MDSs) or Minimum Soil Fertility Index (MSFI); analysis of Soil Fertility Index (SFI). The research results show that the change in function of 231 ha of land in Girimarto Sub-district is due to the topographical factor of the mountain region and the shortage of water. This change in land function has caused an increase in the soil fertility index. Soil fertility in paddy fields is classed as moderate but after undergoing a change in function to dry land, its classification increases to moderate-high. The increase in soil fertility index of dry land is due to the fact that farming patterns on dry land use more animal manure, which has a long-term residual effect on organic matter content. In order to maintain and improve the fertility of paddy field soil, it is necessary to add organic fertilizer as well as inorganic fertilizer.</jats:p

Existences and perception of javanese local knowledge for climate change adaptation

Abstract Farmer perception of their environment is a factor of climate change. Adaptation to climate change requires farmers to realize that the climate has been changed and they must identify useful adaptations and implement them. This study analyzed the adaptation of climate change among rural farmers using local knowledge and knowing the existence of it. Local knowledge was examined by descriptive qualitative. The results showed that Pranata Mangsa crop calendar was used by Javanese society for a long time ago, where, practiced by the indigenous people through their different beliefs, culture, and traditions. Pranata Mangsa comes from two words, Pranata which means rule and Mangsa which means season or time, where, divided into four (4) seasons: Katiga (dry season), Labuh (dry to rainy season), Rendheng (rainy season), and Mareng (rainy to dry season), which each season has natural signs for warning system and move to next season. In addition, the results showed that the Javanese societies said Pranata Mangsa is still relevant (31.71%), need to re-evaluate (22%), not relevant (13.3%), and not answered (33%).</jats:p

Estimation of peak runoff impact from land use change using remote sensing and GIS in Keduang sub-watershed

Abstract Changes in land use in watersheds and climate change have a dominant influence on watershed hydrology. One of the important aspects of watershed hydrology related to land use change and climate change is runoff. Land use changes in the watershed area from non-built areas to built areas or vegetated areas to non-vegetated areas will increase runoff. Because vegetation helps absorb rainwater optimally into the soil. Thus, rainwater that falls to the ground will become more runoff. For this reason, it is necessary to conduct a study to determine the land use changes and impact on the runoff, as has been done in the Keduang sub-watershed, Wonogiri District, Indonesia. Land use change and peak runoff were estimated using remote sensing and Geographic Information System (GIS). Remotely sensed images from the Landsat satellites were used to develop land use maps of the study area in 2009 and 2020. The peak runoff was computed by the Rational Method. The land use map between 2009 and 2020 shows an increase in built areas and dryland agriculture and a decrease in the vegetated area such as a forest and mix garden. The impact of land use change increases the coefficient runoff value in the study area from 0.22 to 0.24. The results showed that peak runoff for 2009 was 358.73 m3/s and in 2020 was 363.38 m3/s there is an increase of 4.66 m3/s.</jats:p
