The City

<p>Surakarta is one of the cities in Java island with a high population growth rate, triggering the increase<br />in the construction, especially for high-rise buildings. The city is close to several earthquake sources,<br />causing a high level of seismic hazard. One of the main parameters of earthquake resistant building<br />design is the value of peak ground acceleration at surface level. It is obtained by multiplying the peak<br />ground acceleration in the bedrock by a multiplier factor that depends on the site class conditions of the<br />location. A previous study has been conducted in 2015 using 32 boreholes indicating that around 19.5%<br />of Surakarta area is classified as SC (hard soil), and 80.5% of the rest is SD (medium soil). To increase<br />the accuracy, another 31 additional boreholes data are adopted. The new result shows that Surakarta is<br />divided into three different seismic site class. Around 4.80% the area is classified as SC (hard soil),<br />94.50% is SD (medium soil), and 0,70% is SE (soft soil). The southern part of Surakarta has a higher<br />level of vulnerability to earthquakes, especially in the border area between Banjarsari, Laweyan, and<br />Serengan subdistricts which have a SE (soft soil) seismic site class.</p>

The high level of human activity in coastal areas has had an impact on seagrass beds. The advancement of satellite imaging technology makes monitoring seaweed conditions even easier. The purpose of this study was to identify the spectral reflectance patterns of different seagrass cover levels and make it the basis for mapping the seagrass condition on Barranglompo Island. Based on google earth has been determined 4 sampling stations that represent the spread of seagrass on Barranglompo Island. Each station is divided into 4 sub-stations from land to sea. Sampling of seagrass cover was carried out by the McKenzie (2003) method modified by close sampling, to 30 x 30 square meters following the spatial resolution of Landsat image 8. Each observation point was estimated the percentage of seagrass cover and the dominant species. Digital seagrass pixel extraction is performed from band 1 to 7 landsat 8 according to point position in the field and then grouped by cover class and condition. Seagrasses found in Barranglampo Island are 8 species: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. In general, Enhalus acoroides and Thalassia hemprichii have higher closure than other seagrass species. The spectral reflection of seagrass landscape imagery 8 OLI channel 1 - 7 is good enough to show the seagrass condition in bad category, good enough, and good. Spectral reflection of the seagrass has a peak on the green channel. The worse the seagrass condition the higher the spectral reflection. Seagrass with bad conditions has a low cover so that other substrates such as sand will contribute to the spectral value recorded by satellite sensors. This result will facilitate mapping of seagrass condition on small islands by using Landsat 8 OLI image.Keywords: seagrass condition, spectral reflection, landsat 8, South Sulawesi

Abstract Background:According to EU regulations, member states shall take measures to encourage the recycling of biowaste in a way that fulfils a high level of environmental protection. In Spain, the separate collection of biowaste is only implemented in some regions. For this reason, a pilot scheme based on an information campaign and the location of a specific brown container for biowaste in specific zones of the city was carried out in Castellón de la Plana (Spain) over a period of six months. In this period, the collection and composition of the biowaste was monitored in depth with the goal of determining the evolution of the efficiency of the new collection system over time. Results:In the zones, the quality rate in the biowaste container increased as the pilot study progressed, finally reaching 90%. The rate of biowaste separation also increased in the three zones over time, although in different ways, which means that there is greater collaboration on the part of citizens. On the other hand, an analysis of the rate of net biowaste daily collection from zones 2 and 3 has shown that their value increases as the rate of containerization of biowaste decreases. Conclusions:In order to obtain better results in the biowaste quality rate it will be necessary to increase the containerization of biowaste, that is, to reduce the distance from the citizen to the container. It can thus be said that there is a positive evolution of the experience, which boosts confidence when it comes to implementing the system throughout the city.
