Abstract

Urban geology is a preliminary study for the construction and development of cities, which has been more prominent in recent decades in some countries despite its long application history. It assesses the impact of geological and natural phenomena on urban space and available structures. The earthquake on Nov. 21, 2017, inflicted a lot of damage to the city of Sarpol-e Zahab, west of Iran, including financial losses and casualties. Reconstruction of this city and planning for its sustainable development entail conducting urban geological studies. In the present study, the effect of natural phenomena on Sarpol-e Zahab County was studied by investigating its geology and geomorphology. The results showed that, in addition to the earthquake that habitually affected the city of Sarpol-e Zahab, the hazards of other phenomena are also significant. Recorded horizontal acceleration in the recent earthquake confirmed the high seismicity of Sarpol-e Zahab has.

Abstract

Soil moisture (SM) is one of the energy and water exchange main drivers between the atmosphere and land surface. The study aims to analyze the soil moisture characteristics in Indonesia on monthly and seasonal time scales. The analysis uses mapping of monthly and seasonal ESA CCI SM satellite products of mean daily from 1979 to 2016. The results showed the spatial and temporal variability of SM in Indonesia. Sumatera has SM values > 0.3 m3/m3 almost throughout the year. Besides, Java has SM values > 0.3 m3/m3 from January to April and October to December while 0.2-0.3 m3/m3 from May to September. In Borneo, the SM value > 0.3 m3/m3 from February to June and November to December, while from July to September are 0.2-0.3 m3/m3. Sulawesi has SM values > 0.3 m3/m3 from January to July, on December, and 0.2-0.3 m3/m3 from august to November. Bali to Nusa Tenggara have SM values between 0.2-0.3 m3/m3 throughout the year, except <0.2 m3/m3 in Sumba, Timor Island, and Central Lombok from June to November. Maluku has SM values between 0.2-0.3 m3/m3 throughout the year, while Papua has SM values >0.3 m3/m3 throughout the year, except in Jayawijaya Mountain and South Papua. The ESA CCI SM product is essential for monitoring SM in Indonesia.

Abstract

Introducing a rail transit system into an urban region is expected to increase land values, and subsequently, residential property values. Despite this general belief, there has been limited research on the impact of proximity to urban light rail transit stations in developing countries setting. This study, therefore, investigates the impact of proximity to urban light rail transit on double-story terraced property values in the Greater Kuala Lumpur, Malaysia, using hedonic pricing model. The findings suggest urban light rail transit has a positive and significant impact on surrounding double-story terraced residential property values – estimated at a premium of 12.3% and 9.8% for properties located up to 1000 m and 1001 – 2000 m to the nearest light rail transit station respectively. The findings of the study are useful for investors and developers, namely to build more houses near urban rail transit infrastructure since they lead to significant appreciation in value.

Abstract

Lawanopo Fault is a horizontal shear fault (sinistral strike-slip) found in Southeast Sulawesi province and is thought to be active during Plio-Pleistocene or mid-late Miocene to the present. This study has been carried out which aims to find out the geometric shapes below the surface of the Lawanopo fault using complete Bouguer anomaly (ABL) data.  The ABL data is projected onto a flat plane using the Dampney method at an altitude of 8 km, and the separation of local and regional anomalies is carried out using the upward continuation method at an altitude of 60 km. Three-dimensional (3D) modeling under the surface of the Lawanopo fault is done using the computer program Grablox. Data processing techniques using Singular Value Decomposition (SVD) and Occam inversion. The results showed that a high gravity anomaly of 190-225 mGal was caused by an igneous rock below the surface with a density of 2.7-3.33 gr/cm3 and a thickness of about 13 km, a moderate anomaly of 175-187 mGal caused by Paleozoic igneous rocks aged Carbon with a density of 2.6-2.9 gr/cm3 and a thickness of about 25 km. Low anomaly 115-160 mGal is caused by rocks with a density of 2.0-2.5 gr/cm3 and a thickness of about 22-23 km. The Lawanopo fault constituent rocks consist of alkaline rocks in the basement covered by sediment and metamorphic with a depth of Lawanopo fault more than 15 km and begin to be seen at a depth of 4.3 km of the surface. it is known that the area around the Lawanopo fault is an area prone to earthquakes. But, based on the soil and rock structure around the Lawanopo fault, the compactness and attenuation levels in reducing earthquake waves are quite good, so that land use around the Lawanopo fault tends to be safe.

Abstract

Many studies have investigated the effects of transit-oriented development (TOD) on density, design, diversity development, and transit ridership. However, fewer studies address the issue of carrying capacity of TOD. This paper aims to assess TOD areas' carrying capacity using four criteria (land capability, water availability, socio-economic, and green infrastructure) and  14 indicators on Jakarta's two TOD areas. These results show that even though both of the TOD area, Dukuh Atas and Lebak Bulus, are in the good of carrying capacity in land capability, there are some issues to address the possibility of water availability. For TOD's success, the socio-economic criteria should be promoted in the fringe-urban TOD area like Lebak Bulus. We identified the green infrastructure, such as pedestrian, cycling route, and green open space, still in low development and should be pursued to extend the TOD carrying capacity for the future.

Abstract

Lineament is one of the most important features showing subsurface elements or structural weakness such as faults. This study aims to identify subsurface lineament patterns using automatic lineament in Citarum watershed with gravity data. Satellite gravity data were used to generate a sub-surface lineament. Satellite gravity data corrected using Bouguer and terrain correction to obtain a complete Bouguer anomaly value. Butterworth filters were used to separate regional and residual anomaly from the complete Bouguer anomaly value. Residual anomaly gravity data used to analyze sub-surface lineament. Lineament generated using Line module in PCI Geomatica to obtain sub-surface lineament from gravity residual value. The orientations of lineaments and fault lines were created by using rose diagrams. The main trends observed in the lineament map could be recognized in these diagrams, showing a strongly major trend in NW-SE, and the subdominant directions were in N-S. Area with a high density of lineament located at the Southern part of the study area. High-density lineament might be correlated with fractured volcanic rock upstream of the Citarum watershed, meanwhile, low-density lineament is associated with low-density sediment. The high-density fracture might be associated with intensive tectonics and volcanism.

Abstract

The Bandung Regency Spatial Plan for 2007-2027 regulates The Patuha Mountain Area as one of the regions that have a special role in the tourism sector. This research was conducted to find out the attractiveness value and motivation of tourists on tourist attractions as well as the relationship between them in The Patuha Mountain Area. Assessment of tourist attractiveness value was based on the completeness of attraction, tourist facilities, and accessibility. Meanwhile, tourist motivation was based on tourist preferences, tourist needs, and tourist travel status. The variables were analyzed using spatial analysis and chi-square test statistics. The results indicated that the high attractiveness value has a nodal destination system, while medium and low attractiveness value has a linear destination system. Tourist motivation was being dominated by flashpacker types. Tourists who visited The Patuha Mountain Area are not being influenced by the attractiveness value of tourist attractions. Although tourist attraction has complete tourist facilities, tourists only focus on the attraction compared to the tourist facilities and accessibility.

Abstract

Sea surface temperature (SST) is an important variable in oceanography. One of the SST data can be obtained from the Global Observation Mission-Climate (GCOM-C) satellite. Therefore, this data needs to be validated before being applied in various fields. This study aimed to validate SST data from the GCOM-C satellite in the Indonesian Seas. Validation was performed using the data of Multi-sensor Ultra-high Resolution sea surface temperature (MUR-SST) and in situ sea surface temperature Quality Monitor (iQuam). The data used are the daily GCOM-C SST dataset from January to December 2018, as well as the daily dataset from MUR-SST and iQuam in the same period. The validation process was carried out using the three-way error analysis method. The results showed that the accuracy of the GCOM-C SST was 0.37oC.

Abstract

The participation of rural people in ecotourism activity remains the question, whether they genuinely carry the vision of conservation or are forced to engage in meeting economic needs only. This question is fundamental for building better participation and management of ecotourism in rural areas. The research aims to discuss social capital and social capacities to empower ecotourism in rural areas. The study was carried out in the villages of Ngadas and Gombengsari using a survey approach, and employing descriptive and path analysis methods. The results show that social capital for managing ecotourism services demonstrated the functioning of institutions, networking capabilities, monitoring, evaluation, and innovation.  Social capacity is related to the regulation of institutional, social, economic, and environmental resources.  Social capacity was found more substantial in Gombengsari than Ngadas village.  The research is expected to strengthen the study of social capital as a stock/sink and its relationship with sustainability.

Abstract

Rice is an essential crop in Indonesia. Any aspects of rice to increase productivity have been well studied and documented; however, there are still lacking well-documented studies on its environmental aspects, including climate change. Many researches might already be conducted, but only a few have been published in a peer-reviewed journal. There is still a lack of robust data on greenhouse gas (GHG) emissions from the rice field in Indonesia, factors affecting and the technology on how to reduce it. From the reviewed publications, it was found out that research only conducted under a controlled environmental setting. More research on understanding the controlling factors (e.g., water management, rice cultivar, soil types, and fertilizer) of GHG emission from rice field is still needed. The result will introduce a sustainable farming practice,  with low in GHG emissions, high in productivity, simple to apply and generate more income to farmers. This review has identified the gaps for future research and development in Indonesia. The research should meet the need, either national or global strategies. Development of a new farming practice will succeed in the presence of government policies. Therefore an intensive interdisciplinary approach between researcher and other stakeholders should be conducted.
