Published: March 2020

Abstract
This research aims to determine the effect of alkaline activation on the zeolite binding properties toward dissolved irons. Natural zeolite was activated by reflux using NaOH with various concentrations (2 N, 4 N, and 6 N). Furthermore, the activated zeolite was mixed into a solution of FeSO4.7H2O 0.5 M. Zeolite-Fe then characterised using FTIR, XRD, and SEM. The optimum contact time and the adsorption of irons by activated zeolite were studied. The result shows that alkaline activation in zeolite caused a change in structure zeolite as evidenced by FTIR spectra. The data from XRD result have also identified diffraction patterns of alkaline activated zeolites run into differences in the peak characteristics of their constituent and changing the degree of crystallinity of the mineral structure in zeolites. Besides, it also observed that NaOH activation of zeolites increased the amount of Fe bound to zeolite as evidenced by changes in colour and SEM results. The optimum contact time is 2 minutes and the adsorption kinetics of irons were fitted well with the pseudo-second-order kinetic model.

The use of space syntax method in mapping passive contacts in slum area of Semanggi, Surakarta
Authors: Putri D K , Marlina A , Purwani O 
Published: March 2020

AbstractSocial interactions happen anytime and anywhere, started with human actions and/or movements. These movements lead to a meeting between people indicating opportunities to know and to admit the existence of each other and discover each other’s nature through observations and conversations. This is called `passive contact`. This research is conducted to test the passive contacts that happen in settlement using space syntax method and then compare it with direct observation. Space syntax works objectively without involving goals and motivation, assuming nothing about the individual and their cognitive capacity explicitly, despite human are moving and socializing to another directed by their cognition. Spatial configuration used in spatial layout of urban space or a settlement, analysed by space syntax methods producing an axial map that presents the degree of connectivity, integrity and intelligibility value. This research used case study method with Semanggi as the case. The results of this research show that space syntax method is not enough to explain how passive contact can be formed. Therefore, additional research needs to be done to cover the factors that can not be covered by space syntax analysis. Direct observation in certain periods is considered very effective to cover the gap of analysis that space syntax could not cover.

Locality and globality: The production of new space in maintaining the identity of urban areas
Authors: Siagian M 
Published: March 2020

Abstract
Globalization has brought modernity to big cities but this led to a contradiction between abstract spaces (quantity) and social spaces (quality). The modern environment tends to disrupt the daily life of local communities with its cultural diversity and eliminates social relations. Moreover, modernity which offers uniformity does not consider local identity and cities are planned similar everywhere. This paper uses Lefebvre’s trialectics of spatiality comprising ‘spatial practice’, ‘representation of space’ (abstract space), and ‘space of representations’ (lived space) to study the spatial phenomena in Medan city. The research used qualitative methodology via in-depth interviews with respondents from various societal groups. The study focused on the phenomenon of space according to each group. The findings show that there are unique dynamic relationships between the local community and the newcomer communitythat brings modernity. The Tamil communitylives in the periphery area while their presence in the modern commercial center strengthens the identity of the area as a “home town” for the local community in the modern city.

Published: March 2020

Abstract
To achieve sustainable development in urban areas requires the active cooperation of all parties, especially the people. The informal settlements in the Kalisari area of Surabaya are still not optimally handled and organized through community participation. This study was conducted to identify the role of the local community, determine the direction of the development concept and assess whether the proposed design suits the Kalisari waterfront development concept as sustainable ecotourism based on Community-Based Tourism (CBT).Literature study and empirical findings contribute to the theory of CBT for economic, socio-cultural, environmental, and life satisfaction aspects. The research method is descriptive-qualitative using both primary and secondary data. The results showed that people support the concept of the CBT-based waterfront development in Kalisari. By producing the relevant design concepts based on CBT, the areas can develop from unproductive into productive areas in terms of economic, socio-cultural, environmental aspects and life satisfaction.

Authors: Yuli N G 
Published: March 2020

Abstract
In the vernacular design method, almost every general building standard cannot apply because of its unique condition. There was not any consideration about building design standards in Pondok Pesantren. They developed the group of buildings only based on the fund and land availability, and then the neighbor duplicated their method. The purpose of this paper is to assess the chances and challenges of Pondok Pesantrens in Indonesia, to develop sustainable Muslim settlements with Mlangi Muslim Settlement in Yogyakarta as a case study. Sustainable Construction Assessment Tool (SCAT) by the Holcim is used as the assessment tool to calculate sustainability. Three aspects are assessed from the economy, environmental and social to draw the existing conditions. The major findings of this research are stated in the environmental aspect; Pondok Pesantren is in a bad state regarding the terrible condition of water, energy, waste and site by the lack of condition of the settlement layout. Pondok Pesantren has chances to improve their environment using some strategies that would encourage the community to take the same action for its improvement as well. Socio-culture challenges need to be solved; the Pondok Pesantren has vowed to prioritize their significant role to make better quality Muslim settlements in Indonesia.

Published: March 2020

Abstract
Traditionally, villager’s houses organised in groups, surrounded by green nature, landscape, each space connected by informal pathways to form a settlement known as village, kampong or ‘kampung’. The kampong setting grow harmoniously and evolved over the years. Indirectly the culture and values of the Malay community in the village are slowly influenced by the atmosphere and living environment that tested through many years. Today, the existence of a traditional Malay village as an early settlement pattern of the Malay community threatened by the process of urbanisation and modernisation of the country. The kampong setting has replaced by mass production of housing schemes called ‘taman perumahan’. As a result, the existence of traditional Malay kampongs in urban areas has been replaced by a planned housing schemes that is considered modern and well-planned. However, there is an effort to re-adapt the traditional village concept ideally into modern urban housing either through architectural design, landscape and neighbourhood planning at different level. This paper is written based on qualitative approach by collecting and structuring field data through several methods such as observation, and fieldwork study. This paper explores such effort in modern housing schemes at the Precinct 8 (Putrajaya) and Nong Chik Height (Johor Bahru).
Spatial negotiations in domestic space of the home-based garment industry in Kampung Tambora, Jakarta
Authors: Lirenzsa F , Ellisa E , Paramitha A 
Published: March 2020

Abstract
With a population of around 260.100 and covering an area of 5.4 km2, Kampung Tambora is one of the densest urban areas in Jakarta. The area is well known for its home-based garment industry, which supports the livelihood of the community. Typically, several houses in one alley run the garment industry business, where both men and women work and live under the same roof. The study aims to understand how all actors in the home-based garment industry negotiate with the limited space to fulfill domestic and working needs. Three houses were selected for observation to understand how all involved actors maximize the use of the limited space through spatial interruption in domestic space. The study found that the actors define the activities through the utilization of space, the allocation of spatial functions, and symbolizing objects. Multi-story houses were built to expand space and enable the owners to work without disrupting the privacy of domestic activities. Although the actors of the home-based enterprises found ways to cope with the issues of crowding, alternative ideas are needed to increase their well-being and improve the environmental quality of similar high-density urban settlements in many parts of Jakarta.

Published: March 2020

Abstract
The traditional city of Surakarta is located in Kampong Baluwarti of Surakarta Sunanate Palace. This traditional city is experiencing rapid development in line with the development of its surrounding areas. However, it is believed that this city still maintains the authenticity of the elements forming traditional urban layout structures. This article focuses on the exploration related to the discovery of the elements which form spatial structures of a city. These elements are the ones able to survive as the embodiment of the authority concept for sustainable synergy with city development. This study employed a qualitative research method namely, the descriptive qualitative with a case study approach. The finding revealed that the most endured forming elements were the kedhaton (palace) as the center, roads as the paths, settlements surrounded by beteng walls and both the north square and south square as the domains. These findings contribute to the ability to overcome conflicts related to urban layout structure in the context of urban development.

Published: March 2020

Abstract
The increasing urban population has triggered a complex waste problem in Indonesian cities. Since the 1960s, waste generation in Indonesian urban areas has increased exponentially. Considering that municipal solid waste management (MSWM) is a case-by-case issue, MWSM practices vary on the municipal level. This article aims to explore the implementation of MSWM in small and metropolitan cities. By distinguishing cities by their typology, this article hopes to understand the similarities and differences of MSWM characteristics. This study uses a case study approach in which Surabaya represents metropolitan cities and Mojokerto represents small cities. The paper compares the current conditions and challenges of MSWM. This study is based on a literature review but also includes simple statistical analysis to strengthen the arguments in this paper. The review found that there are differences in the implementation of MSWM in Surabaya and Mojokerto in almost all aspects. Surabaya faces more complex problems and challenges and comes up with several solutions such as cooperation with a Japanese city and it is tackling human resources issues. On the other side, MSWM in Mojokerto is mostly government-centered and the city still has to handle institutional limitations such as regulatory issues, limited resources, and lack of participation.
