Abstract

This study focus on calculating the carbon footprint from the activities of the Universitas Airlangga. CO2 emission calculations were carried out using the UI GreenMetric method and the Intergovernmental Panel on Climate Change (IPCC) in two periods: before the Covid-19 pandemic and during the Covid-19 pandemic. Activities at Universitas Airlangga that produce carbon footprints are divided into two main sources, first, primary sources that come from direct combustion of fuel into energy, such as burning fuel in motorized vehicles and a secondary source that comes from an indirect source of using electricity in the campus area. The results showed that in the period before the pandemic, the total carbon emissions, based on the IPCC calculation method, were 23.830,34 tons of CO2-eq/year. Meanwhile, based on the UI GreenMetric method, a total carbon emission of 26.325,36 tons of CO2-eq/year was obtained. As for the time period during the pandemic, Universitas Airlangga's total carbon emissions obtained based on the IPCC calculation method were 20.506,69 tons of CO2-eq/year. Meanwhile, based on the UI GreenMetric method, a total carbon emission of 22.321,63 tons of CO2-eq/year was obtained. Secondary carbon footprint mapping is carried out to ascertain the distribution of secondary CO2 emissions produced by Universitas Airlangga. The secondary carbon footprint both before and during the Covid-19 pandemic was mostly generated by the Universitas Airlangga Hospital.

Abstract

Nanopartikel magnetis ZnFe2O4 telah disintesis menggunakan metode presipitasi untuk degradasi rhodamine B dengan penyinaran cahaya UV dan cahaya tampak. Analisis pola difraksi sinar-X dan spektrum Fourier Transform Infrared (FTIR) menunjukkan pembentukan kubik spinel ZnFe2O4 dengan ukuran kristalit sekitar 13 nm. Spektrum absorpsi dalam rentang cahaya UV (200 nm) sampai cahaya tampak (~ 600 nm) dan celah energi 2,04 eV teramati dari pengukuran spektrofotometer UV-Vis. Sifat magnetik nanopartikel diukur menggunakan vibrating sample magnetometer (VSM) menunjukkan sifat magnet lemah yang sesuai untuk aplikasi magnetis fotokatalis. Nanopartikel ZnFe2O4 menunjukkan aktivitas fotokatalisis dengan cahaya UV maupun cahaya tampak untuk degradasi rhodamine B dengan konstanta laju reaksi 8,2 x 10-3 /menit dan 4,5 x 10-3/menit.

Abstract

Abstract The commercialization of public spaces is increasingly common in major cities, transforming areas once open and freely accessible into spaces focused on commercial activities. This shift not only changes the primary role of public spaces as venues for social interaction but also introduces challenges and opportunities for economic security. From an economic security perspective, the commercialization of public spaces offers both benefits and risks for communities and local governments. On one hand, it can stimulate economic growth through increased business activities, job creation, and urban revitalization. On the other hand, it can exacerbate socio-economic inequalities, marginalize vulnerable groups, limit access, and erode the social function of public spaces. This study investigates the impact of public space commercialization on economic security, focusing on how this transformation affects accessibility, economic disparity, and social welfare sustainability. Through literature analysis and case studies, the study provides comprehensive insights into managing public space commercialization sustainably while upholding inclusive and equitable economic security principles. The findings indicate that while commercialization offers economic opportunities, it also heightens social inequality, highlighting the need for inclusive policies to safeguard economic security. These findings aim to guide policymakers in balancing economic interests with the social functions of public spaces, ensuring that policies are inclusive, equitable, and support sustainable economic security for all societal groups

Abstract

Juvenile delinquency remains a persistent issue in major cities, including Surabaya. In response, the Surabaya City Government established a grassroots organization, Kader Surabaya Hebat (KSH), to support community-level monitoring and problem-solving at the sub-district level. This study employed a mixed-methods approach involving 50 KSH cadres in Pradah Kalikendal Sub-district. Data collection consisted of three stages: pre-test and post-test questionnaires to assess cadres’ knowledge of juvenile delinquency, and a focus group discussion (FGD) to explore challenges encountered in the field. The findings indicate that KSH cadres possess moderate to high levels of knowledge regarding juvenile delinquency and are generally well-prepared to perform their roles. However, low levels of trust between the community and KSH cadres emerged as a key challenge. As trust is a central component of social capital, its absence hinders effective collaboration and community development. This study recommends strengthening social capital by improving social relations and fostering trust-building strategies to enhance the effectiveness of KSH cadres in addressing juvenile delinquency.
