Integrated sustainability index of east Surabaya with casbee tools toward a sustainable city

Abstract

Surabaya is a city that continues to grow from year to year. Various problems that can be identified in the city of Surabaya include population density due to immigration. Statistics show that in 2014 Surabaya’s population reached 3,020,305 million with a total poverty line of 168,000 people or 5.97% of the total population. Surabaya east is one of the industrial areas in Surabaya which contributes to increasing emissions. This research is focused on the East Surabaya area with samples in Kendangsari Village, Rungkut Kidul Village and Rungkut Tengah Village. The three locations have the same character in the form of industrial estate supported by residential areas both settlements and surrounding housing. This research uses descriptive quantitative and qualitative approaches. Observations were made on several environmental aspects which were grouped into aspects of Quality (Q) and load (L). These aspects are aspects of the assessment of the Comprehensive Assessment Built Environment Efficiency - Urban Development (CASBEE-UD) index. Based on calculations it is known that the index for the East Surabaya region is (B +) Good, this index shows the quality level of the region one level below the quality of sustainable areas. The index results indicate that the region is approaching a sustainable status. Based on the results of calculations and scoring it is known that the environmental quality in this region is good at 3.5 (three points five), with a breakdown of the environmental quality index of 2.4 (two-point four), social quality index of 3.8 (three-point eight) and economic quality index of 4.4 (four-point four). However, the environmental burden received by this region is moderate, so the score obtained is 2.7 (two points seven).

Characteristics of Conceptually Related Smart Cities (CRSCs) Services from the Perspective of Sustainability

“…Mori et al (2020) introduce a visualized model of City Sustainability Index (CSI), along with three pillars of sustainable development [6]. Alfaro (2017) develops an index based on the triple bottom line using an intellectual capital approach [34]. The sustainable city literature mostly deals with three pillars for sustainable development, excluding smart city indicators.…”

“…U4SSC proposes 90 indicators under ICT, productivity, infrastructure, environment, energy, education, health, culture, safety, housing, and social inclusion pillars [31,32]. under the categories: the geographically balanced settlement, the freshwater, wastewater, the quality of ambient air and atmosphere, the noise pollution, the sustainable land use, waste generation and management, health, safety, fire and emergency response, poverty, transportation, natural hazards, adequate housing, shelter, the security of tenure, access to credit, access to land, promote social integration and support disadvantaged groups, culture, recreation, availability of local public green areas and local services, participation and civic engagement, transparent, accountable and efficient governance, government, sustainable management of the authorities and businesses [6,8,26,[33][34][35][36] The literature addressing smart city services is selected from the Google Scholar results using keywords of smart, city, and service models. The inclusion criteria are the literature published from urban-related journals, which means the technical-driven journals are excluded due to the study orientation.…”
