Abstract

CO2 concentration is one air quality parameter set by WHO. High concentrations of carbon dioxide will have an impact on human health. CO2 is a gas that can cause a greenhouse effect in a city like Surabaya. This study aims to reveal the dynamics of CO2 concentration in northern Surabaya, which is a center of urban activity in Surabaya. This type of research is descriptive analytic with a quantitative approach. The population used is based on the division of administrative regions in Surabaya u tara section. Sampling is carried out in a purposive way, where each land use is taken five locations. Data collection techniques use measurement and observation. The data analysis technique used is descriptive. The results of the data analysis showed that there was a difference in the average CO2 concentration in the morning and evening. All research sites have CO2 concentrations above the safe threshold of CO2 concentrations set by WHO. There is an increase in CO2 concentrations in the morning and evening variably. The average CO2 concentration in the morning was recorded at 436.05 ppm and increased at night to 518 ppm. The highest CO2 concentration in the morning occurred on Colombo road at 467 ppm and the lowest at 345 ppm on Bangunsari road. The highest average CO2 concentration at night occurred on Morokrembangan road, which was 558 ppm and the lowest on Bangunsari road was 460 ppm. Keywords: CO2 concentration, air pollution, northern Surabaya

Abstract

The focus of this research is to describe the participation model of the Airlangga Village community in the KOTAKU program. This study is essential because, empirically, community participation in the Airlangga sub-district has been going well and is sustainable in protecting the environment. It is necessary to study the model and form of participation implemented through the involvement of PUPR, local government, government partners, the private sector and the village community. Examining the internal and external factors that support collaboration, the designed collaborative model is expected to contribute suggestions for solving slum areas in other regions. Using a quantitative research approach, this study produced the following data: 1). The form of participation used by 99 respondents was 20% using thoughts, 29% using energy and 22% using expertise and 16% using materials or money. 2). The collaboration model used by the Airlangga sub-district is 4-Key or 4K, namely Institutionalism, Citizen Control, Facilitative Leadership and Communication. 3) Factors that influence community participation are age, gender and level of education. External factors that influence community participation are communication, leadership and the role of the facilitator

Abstract

Filtration is a very important process because naturally karst landscapes do not provide good protection against groundwater. This study aims to determine the effect of filtration with sand, biocarbon, and zeolite materials on the pH, EC and TDS values. The research was conducted using an experimental method using three filtration tubes filled with these three materials. Samples were taken from ten different water sources. The results of the analysis show that the filtration process of a combination of sand, biocarbon, and zeolite materials has the effect of increasing the pH value, and decreasing the EC and TDS values. The filtration process through a combination of volcanic sand, biocarbon and zeolith materials simultaneously gives a more significant change in pH, EC, and TDS values compared to filtration with these materials separately.

Abstract

This study aimed to examine the spectral imagery of Landsat 8 OLI  that can determine the level of tropical karst desertification Maros Pangkep South Sulawesi. The study method is based on the characteristics of spectral imagery of Landsat 8 OLI. Spectral characteristic analysis was conducted based on derivative index values of Landsat 8 OLI of single-channel spectral values, index spectral values, maximum values, mean, minimal index, and spatial analysis. The results showed that spectral imagery of Landsat 8 OLI can be used as the identifier of the desertification process, that is in band 5 whose maximum value is indicated by the spectral value of vegetation. The karst desertification level in the study area showed that 0.3% of the regions were strongly desertified or 0,97 km2 , 4.1% of medium desertified or 12,03  km2, 16.7% were mildly desertified or 49,17 km2, and 78.9% were not desertified or 232,57 km2. Observation results for image accuracy shows that strongly desertified areas of land use are mining and cement industries, the medium desertified areas are utilized for marble mining, the mildly desertified areas are utilized for agricultural land, and not desertified areas land are being utilized for tropical rain forest is still dense.
