Authors: Sunarti  , Yuliastuti N , Tyas W P , Sari D P P 
Published: March 2020

Abstract
Housing backlog is a difficult problem to deal with, especially for low income communities. A way to reduce home ownership backlog in Salatiga City is the development of housing for KORPRI members, but now the ownerships and functions have changed. Based on these problems, the purpose of this study is to examine the development of KORPRI housing in Salatiga City with its problems and sustainability. The analysis technique is descriptive quantitative using data collected by distributing questionnaires to 40 households randomly and field observations of houses, its facilities and infrastructure. The results showed that low-cost housing development programs for civil servants of KORPRI members in Salatiga City had changed ownership of 62.5% to other people who were not low-income people and did not help reduce the backlog. The mechanisms and initial commitments were violated a lot by civil servants, who were the buyers, leaving many problems. The sustainability of housing development for KOPRI members that used government-owned land assets is to reduce the occupancy backlog, not the ownership backlog, i.e. houses with usufructuary rights.
Territorial space: Structural changes in a religious tourism area (The case of Kampung Mahmud in Bandung,West Java, Indonesia)

Published: March 2020

Abstract
At specific periods in time, settlements will experience changes (transformations) related to time and human activities. Such change is a process of adapting and responding to human needs for space. In Kampung Mahmud, religious tourism such as Muslim pilgrimage activities and Islamic events in the settlement causes changes in the space of settlements, especially in dwellings. This study aims to determine the territorial structural changes of settlement spaces when religious tourism activities in Kampung Mahmud take place. This research uses a mixed-method approach of quantitative and qualitative methods. The observed transformation is in the form of transient or temporal changes of space. The observed changes during religious tourism activities were territorial shifts from private areas to shared areas. A shift in territorial structure could be seen as an increase or decrease in structure. The study found three schemes of territorial structure changes in Kampung Mahmud; the settlement experienced an increased shift in territorial structure in both the outer and inner spaces of the settlements. The three schemes of the shifting territorial structures create a shared space.
Cross-programming to reuse old buildings for new functions: The case of Omah Lawa in Surakarta
Authors: Mutiari D , Novianty R 
Published: March 2020

Abstract
Old buildings are a living testament of the past. Although reminiscent of colonial times, buildings from the Dutch colonial era in Indonesia contain a lot of knowledge of building art. One building in the city of Surakarta that is still considered beautiful is Omah Lawa. Unfortunately, the building has not been used for a long time, so it is inhabited by bats. This paper addresses the problem of finding a new function so that this building can be used optimally. First, the paper addresses the concept of conservation of buildings. Adaptive reuse is a conservation theory that allows changes in function in old buildings to adapt to current conditions. This case uses the design method of cross-programming which was introduced by Bernhard Tsumi. Old buildings used to have simple functions such as residences. Now, these buildings are no longer in the residential zone but in the zone of public buildings. As such, its former utilization is no longer permitted. This study used cross-programming to change the function of Omah Lawa in Surakarta into a gallery and a location to market art products. The internal layout was changed to host the new functions while making as few changes as possible to the building.

Abstract
This study investigates the current conditions of indoor air quality, focusing especially on formaldehyde and TVOC, and their effects on health among occupants in the educational buildings located in the city of Bandung. A total of 120 respondents were interviewed and 40 rooms were measured from September to November 2018. The results indicated that around 50% of the respondents in the buildings showed some degrees of chemical sensitivity risk. More than 60% of the measured formaldehyde levels in the buildings exceeded the WHO standard, 0.08 ppm. The respondents studying in rooms with higher mean formaldehyde values tended to have higher multiple chemical sensitivity risk scores.
Sustainable river management: Land use, building coverage, and infrastructure typology of the riverbanks
Authors: Rini E F , Rahayu P , Sinniah G K 
Published: March 2020

Abstract
Surakarta City is intersected by three major rivers which could become the city’s source of clean water. However, pollution of the rivers makes processing this surface water a necessity to create clean water for domestic uses. This study aims to establish a river typology based on the riverbank characteristics and the potential of the surface water to be discharge into clean water. This paper uses spatial analysis to develop typologies and describe the riverbanks characteristics by using the Pepe River in Surakarta as a case study. This is one of the polluted major rivers that flow through Surakarta City. The study found that the Pepe’s riverbanks are dominated by residential and commercial areas. Due to the lack of waste infrastructure, the community (household and small-scale industries) disposes its untreated wastewater directly into the drainage channel. With regard to this problem, five river typologies were established to function as the basis of recommendations to improve the water quality of the river so that it can be used as an urban clean water source. The result shows that all typologies major problems are the lack of wastewater management. The study proposes interventions in waste management, wastewater treatment system, and land use control.
Design visioning in a slum upgrading program: Case study of Ambulu Village, Cirebon Regency, Indonesia
Authors: Pradifta F S , Purnama I , Aji R R , Sulistyo G 
Published: March 2020

Abstract
Design visioning is an approach to formulating the development objective for a planned area. It is based on the input from multiple analyses which results in a clear vision statement. This vision acts as a framework for planning and designing physical interventions. To accomplish the Ministry of Public Works and Public Housing’s directive of “transforming the kampongs’ face” in its slum upgrading program, visionary goal-setting is needed to look beyond physical interventions in infrastructure planning. In fact, the eradication of all slum indicators should not be viewed as an end goal but as a way to improve kampongs’ socioeconomic conditions by creating more liveable and sustainable settlements. Using contextual analysis, followed by SWOT analysis and site analysis, this paper generates general development strategies. The study found that the economic and ecological setting of Ambulu Village in Cirebon Regency has the potential to be promoted into a new maritime-themed tourism destination. The paper presents a vision statement for “Ambulu Eco Fishing Village” as the basis for a set of design principles for developing a slum upgrading masterplan.

Authors: Soedwiwahjono  , Pamardhi-Utomo R 
Published: March 2020

Abstract
The karst area is a strategic area with economic, scientific, and humanitarian values related to livelihood. The karst area of Wonogiri is part of the Gunung Sewu Area, a Global Geopark established by the UNESCO Global Geopark Network. The local inhabitants have not gained any benefit from the potential natural resources. Meanwhile, they are constrained by the harsh nature and the obligation to preserve the karst area. This leads to the question of how spatial planning could intervene inthe socio-economic conditions of the inhabitant by utilizing the natural resources of the karst. The study first describes the characteristics of karst areas from their potentials, problems, opportunities, challenges, and trends. The result of the study is the spatial arrangement of the karst area in Wonogiri based on karst classification and its nature. The karst area can be developed based on its natural resources, such as for agriculture, livestock, special tourism attractions utilizing the landscape and natural formations, including the sustainable exploitation of mineral resources. It can also be used and a source of knowledge. The challenge faced is the obligation to protect its uniqueness related to its geology, geomorphology, paleontology, hydrology, flora and fauna, and the development of knowledge repertoire.

Published: March 2020

Abstract
Rural poverty is still a major problem for regional development in Indonesia. Kecamatan Kokap (district) in Kabupaten Kulon Progo, which is part of the Strategic Region for the New Yogyakarta International Airport (NYIA), is a rural area that has the highest rate of poverty inKulon Progo. In fact, the development of NYIA and its strategic regional development plan will transform conditions and the main activities from a rural setting to more urban and agricultural activities into non-agricultural activities. This study aims to investigate the characteristics of rural poverty in Kokap using the deprivation trap of poverty, a framework that describes rural poverty as a multi dimensional condition. The study uses a quantitative approach and employs interviews directed via questionnaires with poor households in Kokap as the respondents. The sampling technique used is probability sampling with incidental sampling, in addition to descriptive statistical analysis techniques. The results show that rural poverty in Kokap Sub-district is a complex phenomenon that is strongly influenced by the regional conditions where the poor families live. This is a key finding in formulating strategies to prevent poor rural communities to be caught in a poverty trap amid significant changes that will occur in thearea.

Published: March 2020

Abstract
Small Tourism Firms (STFs) has been acknowledged by scholars as one of the main features for tourism development especially in the area that received rapid urbanization. Knowledge on the influences of urban morphology with the specific references on tourism entrepreneurship had already started on the early 1980s. However, previous effort were only considering on the theoretical and empirical point of view and focusing on the classification of characters in comparison to other form of small and medium enterprises. The existing literature does not literally cover the understanding of growth and failure of STFs especially in the perspective of financial aspects. Thus, this paper examines the financial factor related to growth and failure of STFs that emphasis on the factors affecting the growth of STFs in the accommodation sector. Langkawi has been selected as the study area due to its superiority as one of the best tourism destinations in Malaysia. An in-depth interview method has been conducted with 10 potential respondents in representing the small firms. The result from the thematic analysis shows that aspects such as access to the loans, financial constraint and finance tendency were established in understanding the financial influence towards the growth of STFs. The critical success factor, from the perspective of financial is critical especially for the governance and coordination urban-rural towards balance development.
Identification of transportation movement patterns based on the home base approach: A case study of Lembang District, West Bandung Regency
Authors: Judiantono T , Susanto M I P 
Published: March 2020

Abstract
Transportation planning generally uses a traffic model approach. The disadvantage of the traffic model is that it does not consider the movements to and from an area by the community. Therefore, this study uses a home base approach to study the real movement patterns in Lembang District, West Bandung Regency, West Java Province. Lembang District is a geographically strategic region and a center of agriculture and tourism in West Java Province. It is also located adjacent to Bandung City. These characteristics potentially cause a high frequency of transportation movements in the district of Lembang. The study found that the home base approach can accurately show the real movement patterns that the traffic model approach might not uncover. Moreover, the transportation movements of the community of Lembang District are mostly directed to Lembang Village and Bandung City. Furthermore, the findings of this study might differ if the home base approach would use proportional sampling.

Published: March 2020

Abstract
Street network is a city crucial element. The current guidelines of road design generally include road width, cross-sections and street hierarchy which are to be taken into consideration during the design phase of the network. Research have shown that road orientation affects the quality of a housing subdivision. However, there are limited studies on street orientation with most of them concentrating on the effects of the orientation on housing subdivision rather than the factors which give rise to its orientation. This research aims to analyse the street network of housing subdivisions located within Majlis Bandaraya Iskandar Puteri (MBIP) to identify the aspects which influence its orientation. Street networks of 71 housing subdivisions under the administration of MBIP were extracted using the OS Mnx Python programming tool to visualize the street networks in terms of polar charts. The findings of the study imply that the size of a housing subdivision does not affect the manner of streets within it are designed. Street pattern is associated with the time of development and the socioeconomic status of the community within the housing subdivision. Such findings contribute to better understanding of street orientation and can assist urban planners to create a better living environment.
Enhancing reliability of InGaN/GaN light-emitting diodes by controlling the etching profile of the current blocking layer
Authors: Su Shui-Hsiang , Tseng Chun-Lung , Shen Ching-Hsing , Hsieh I-Jou , Lin Yen-Sheng 
Published: March 2020

Abstract
SiO2 was used as the current blocking layer (CBL) during fabricating the InGaN/GaN-based light-emitting diodes (LEDs). The SiO2 film was prepared by plasma enhanced chemical vapor deposition (PECVD) at a lower temperature (LT) of 180 °C and a higher temperature (HT) of 280 °C for characterizing the reliability of LEDs. The degradation of output power in LT-CBL LED is as high as 6.8% during 1000 h in the high-temperature and humidity (85 °C/85 RH) condition. Experimental results demonstrate the low temperature grown CBL forms a larger side-wall angle via wet etching. The thinner side-wall ITO film cracks and the current spreading effect is suppressed, causing drastic power degradation. On the contrary, the HT-CBL SiO2 demonstrates optimal step coverage of ITO film for current spreading and then the HT-CBL LEDs slightly degrade as low as 5% in the accelerated reliability test. A dense quality of HT-CBL SiO2 as well as a good CBL decreased parasitic optical absorption in the p-pad electrode and p-finger. Besides, the HT-CBL SiO2 showed a small side-wall angle of 40˚ which increased the step coverage and current spreading of ITO. An approach is conducted to confirm the side-wall profile of CBL for each process.

Abstract
We investigated the temperature dependence of resistivity in thin crystals of FeSe1−xTex (x = 1.0, 0.95, and 0.9), though bulk crystals with 1.0 ≧ × ≧ 0.9 are known to be non-superconducting. With decreasing thickness of the crystals, the resistivity of x = 0.95 and 0.9 decreases and reaches zero at a low temperature, which indicates a clear superconducting transition. The anomaly of resistivity related to the structural and magnetic transitions completely disappears in 55- to 155-nm-thick crystals of x = 0.9, resulting in metallic behavior in the normal state. Microbeam x-ray diffraction measurements were performed on bulk single crystals and thin crystals of FeSe1−xTex. A significant difference of the lattice constant, c, was observed in FeSe1−xTex, which varied with differing Te content (x), and even in crystals with the same x, which was mainly caused by inhomogeneity of the Se/Te distribution. It has been found that the characteristic temperatures causing the structural and magnetic transition (T
t), the superconducting transition (T
c), and the zero resistivity (T
c
zero) are closely related to the value of c in thin crystals of FeSe1−xTex.

Published: March 2020

Abstract
The transformation of carbides in a 1.9Cr-1.4Mo-0.3 V secondary hardening steel that was subjected to over-ageing at 600 °C–700 °C has been investigated. The carbides were characterized using scanning electron microscope (SEM), x-ray diffraction (XRD), inductively coupled plasma-atomic emission spectrometry (ICP-AES), and transmission electron microscopy (TEM) preformed on carbon replicas. The results indicate that MC, M2C, and M3C were formed during over-ageing from 600 to 700 °C, whereas M7C3, and M23C6 started to be formed at 650 and 700 °C, respectively. In addition, the co-existence of hexagonal and orthorhombic M7C3 structures in a carbide particle was firstly observed. M3C was transformed to other carbides, and the formation of both M2C and M23C6 may follow the ‘separate nucleation’ mechanism, whereas M7C3 was transformed from M3C via the ‘in situ nucleation’ mechanism. The crystallographic orientation relationships between the in situ transformed M7C3 and M3C are

Authors: Ju Lin , Bie Mei , Shang Jing , Tang Xiao , Kou Liangzhi 
Published: March 2020

Abstract
Janus two-dimensional (2D) materials, referring to the layers with different surfaces, have attracted intensive research interest due to the unique properties induced by symmetry breaking, and promising applications in energy conversion. Based on the successful experimental synthesis of Janus transition metal dichalcogenides (TMDC), here we present a review on their potential application in photocatalytic overall water splitting, from the perspectives of the latest theoretical and experimental progress. Four aspects which are related to photocatalytic reaction, including the adsorption of water molecules, utilization of sunlight, charge separation and transport, and surface chemical reactions have been discussed, and it is concluded that the Janus structures have better performances than symmetric TMDCs. At the end of this review, we raise further challenges and possible future research directions for Janus 2D materials as water-splitting photocatalysts.
Sr1-xCaxFe1-yCoyO3-δ as facile and tunable oxygen sorbents for chemical looping air separation
Authors: Dou Jian , Krzystowczyk Emily , Wang Xijun , Richard Anthony R , Robbins Thomas , Li Fanxing 
Published: March 2020

Abstract
Chemical looping air separation (CLAS) is a promising technology for oxygen generation with high efficiency. The key challenge for CLAS is to design robust oxygen sorbents with suitable redox properties and fast redox kinetics. In this work, perovskite-structured Sr1-xCaxFe1-yCoyO3 oxygen sorbents were investigated and demonstrated for oxygen production with tunable redox properties, high redox rate, and excellent thermal/steam stability. Cobalt doping at B site was found to be highly effective, 33% improvement in oxygen productivity was observed at 500 °C. Moreover, it stabilizes the perovskite structure and prevents phase segregation under pressure swing conditions in the presence of steam. Scalable synthesis of Sr0.8Ca0.2Fe0.4Co0.6O3 oxygen sorbents was carried out through solid state reaction, co-precipitation, and sol-gel methods. Both co-precipitation and sol-gel methods are capable of producing Sr0.8Ca0.2Fe0.4Co0.6O3 sorbents with satisfactory phase purity, high oxygen capacity, and fast redox kinetics. Large scale evaluation of Sr0.8Ca0.2Fe0.4Co0.6O3, using an automated CLAS testbed with over 300 g sorbent loading, further demonstrated the effectiveness of the oxygen sorbent to produce 95% pure O2 with a satisfactory productivity of 0.04 gO2 gsorbent

AbstractCitizen science data have already been used to effectively address questions regarding migration, a fundamental stage in the life history of birds. In this study, we use data from eBird and from 3 additional regional citizen science databases to describe the migration routes and timing of the red-footed falcon Falco vespertinus in the Mediterranean region across 8 years (2010–2017). We further examine the seasonal and yearly variation in migration patterns and explore sites used during the species migration. Our results suggest that the autumn passage is spatially less variable and temporally more consistent among years than in spring and that birds migrate faster in spring than in autumn. The species seems to be more prevalent along the Central Mediterranean during spring migration, probably as a result of the clockwise loop migration that red-footed falcons perform. There was a high variation in annual median migration dates for both seasons as well as in migration routes across years and seasons. Higher variation was exhibited in the longitudinal component thus indicating flexibility in migration routes. In addition, our results showed the species’ preference for lowlands covered with cropland and mosaics of cropland and natural vegetation as stopover sites during migration. Stopover areas predicted from our distribution modeling highlight the importance of the Mediterranean islands as stopover sites for sea-crossing raptors, such as the red-footed falcon. This study is the first to provide a broad-scale spatiotemporal perspective on the species migration across seasons, years and flyways and demonstrates how citizen science data can inform future monitoring and conservation strategies.
