Authors: Khotimah N. 
Published: November 2019

Abstract
Pranata mangsa is a Javanese calendar used by farmers to start the planting period and agricultural activities. Pranata mangsa in a modern farming today no longer becomes a rule or “paugeran” in agricultural activities, especially wetland farming, but it serves as controllers of the existing farming activities. Pranata mangsa is still used by farmers in Imogiri sub-district as a controller of agricultural activities. As a controller, it provides considerations in performing agricultural land management. Those considerations are relevant with the sustainable land resources management. Its relevance deals with farmer's decision in determining the type of land use, crop rotation, and the type of dominant crop in Imogiri sub-district. This research aims at investigating: (1) the characteristics of agricultural land resource management in Imogiri sub-district, (2) how far the farmers in Imogiri sub-district utilize pranata mangsa to maintain the sustainability of agricultural land resource management. This research was conducted in Imogiri sub-district. The research location was determined purposively. The population of this research is farmers. The research sample consists of 369 farmers. The research data include primary and secondary data. The primary data were collected using observations and interviews, while secondary data were gathered using documentation techniques. The collected data were analyzed by employing quantitative-descriptive methods based on the frequency table data. The results show that: (1) the characteristics of agricultural land resource management in Imogiri subdistricts are based on: (a) the type of land use i.e. irrigated rice field, rainfed rice field, and dry land, (b) the rotation of crops i.e. irrigated rice fields include paddy-paddy-paddy, rainfed rice fields consist of paddy-paddy-palawija (secondary crops), and dry land consists of paddy-cassava, (c) the dominant types of agricultural crops i.e. irrigated rice fields is paddy, rainfed rice fields consist of paddy-palawija, and dry land consists of paddy-cassava (2) farmers in Imogiri sub-district utilize pranata mangsa to maintain the sustainability of agricultural land resource management i.e. 86.2% in irrigated rice field, 92.7% in rainfed rice field, and 88.6% in dry land.

Abstract
The existence of built up areas on a river floodplain pose a threat during floods and causes socio-economic losses. The latest flood which happened in 2016 in the urban villages of Ulujami and Cipulir, South Jakarta, inundated dozens of buildings and more than a hundred of the residents were evacuated. The flood occurred because many of the residents have houses and even the government has built business structures on the Pesanggrahan River floodplain area for many years. Therefore, a spatial approach is needed for assessing economic losses by identifying the building category and conducting direct interviews with fifty respondents who lived in the area of study. The results showed the distribution of the losses due to floods is different between the southern and northern area of study, where the higher losses are more distributed in the southern area dominated by business buildings. The assessment of the economic losses according to the return period of flood event is 2,970 million rupiah or 223,750 USD (for 5 years return period), and 4,150 millions rupiah or 311,250 USD (for a 100 year return period). The result of this study is not only the amount of losses, but also the spatial distribution of the economic losses. Ultimately, this study is very useful for stakeholders as an effort to reduce the loss impacts due to floods, particulary in facing climate change effects.

Published: November 2019

Abstract
Population growth has resulted in the increase of settlements. Settlements in urban areas are getting crowded, including many hotels that require abundant water supply. Groundwater needed by the population is huge. Settlement constructions cannot be stopped. The next target area is land outside the urban areas. Some areas outside the northern urban areas are water catchment areas, the southern slopes of Merapi. Based on these problems, the major changes of land and river flow coefficient, one of the rivers on the southern slope of Merapi are studied.
The sample of the research is the river flow area of Code. The Code catchment area shape extends from the south to north. The flow coefficient is calculated based on the comparison of annual water volume between 2003 and 2012. This year sampling considers data completeness, land use data, rainfall data, and current data in Pogung Automatic Water Level Recording (AWLR).
The results show that a change in land use over the past 10 years has occurred. The total volume of river water in 2003 was 15.3 cubic meters, while the volume of flow in 2012 was 41.7 cubic meters. The value of the flow coefficient in 2003 was 0.262, while the flow coefficient in 2012 was 0.636. This research suggests that it requires to be built 180,400 recharge wells. The artificial recharge model is adapted to the topography, groundwater depth, and infiltration of each region.

Abstract
Landslide is a frequent disaster in Indonesia that is affected by several factors. Cisolok, Cikakak, Pelabuhanratu, and Simpenan are Sub-district that has physical characteristics which can increase the potential of landslides in the area. Therefore, mitigation efforts by potential landslide mapping are needed in the research area. In this research landslide potential map was made by using 3 methods: SMORPH (slope morphology), Index Storie, and SINMAP (stability index mapping). This study is aim to knew the differentiation of spatial pattern of the landslide potential areas by SMOPRH, SINMAP, and Index Storie methods. Spatial analysis was implemented by overlay technique between landslide potential area with landslide location. The result reveal that the research area was dominated by high potential based on the SMORPH method, low by SINMAP, and moderate by Index Storie. The result also reveal that 33% of the total research area has different potential and 7% has the same potential in the results of all three methods. Where areas with high potential in all three methods was distributed in the northern of the study area. The SMORPH method has 19,951 Ha of high potential area and there are 34 landslides in it, SINMAP 2,568 Ha with 32 landlsides, and Index Storie has 4,684 Ha with 21 landslide. The result also explain that in addition to thbeside of slope gradient factor, landuse change factor has a very big affecting for the occurrence of landslide in the research area. Mapping of landslide potential areas in this research is may practically be applied for the regional planning and development of infrastructures in the area.

Abstract
Fires associated with land use conversion activities such as agricultural expansion, palm and pulp plantations, peat land alteration, and industrial deforestation are significant in Indonesia (Jerrod & Alex, 2015). Fires season in 2015 is one of the worst incident in Indonesia since 1997, it made Indonesia at the second position as an emitter country, at least 22 days in September 2015, and generated more than the daily average emission of U.S. economic activity. A study from the National Development Planning Agency (Bappenas) and Asian Development Bank (ADB) estimated that the amount of land affected by fires reaches 9.75 million hectares. It caused losses reached US$.4.861 or equivalent to IDR711 trillion or even more based on disruption of economic activities, transportation problems, and health problems. Head of Data Information and Public Relations of National Disaster Management Agency (BNPB), Sutopo Purwo Nugroho, said the economic impact of smog disasters occurring in several provinces in Indonesia in 2015 could exceed 20 trillion per province. The most widespread forest fire area occurred in South Sumatra Province. BNPB released that during 2015 in South Sumatera Province has 35.008 hotspots and the burnt area is 641.964 Ha. The most affected area is in Ogan Komering Ilir Regency. Landsat 8 OLI TIRS has a 30-meter spatial resolution for each band except TIRS band and panchromatic band (USGS, 2016). TIRS band has a 100-meter spatial resolution but are resampled to 30-meter that can be used to identify burned scars area. By using SWIR bands (TM bands 5 and 7 in Landsat 5 and 7 systems) as a NBR (Normalized burn ratio) composite, can be used to detecting and mapping burnt area. TIRS algorithm which was used to detect fire will be seen red and SWIR which was used to detect water stress in vegetation and burned vegetation will be seen green, both of them will become darker when burn happened. This method modifying dNBR (pre-NBR – post-NBR) composite, which only can be used in oil palm plantations area that has same commodities, so can be used in various type of landuse especially the area that has plantation adjoin with forest area.

Abstract
This study is assessing the ecological integrity of landscape condition to maintain freshwater biodiversity at highly urbanized catchment using geographic information system (GIS). GIS tools were used to calculate the percentage of land use types i.e. impervious cover, vegetation cover, and water body at 6 sub-catchments of Universitas Indonesia (UI) Depok campus. In order to evaluate freshwater biodiversity, 478 samples of macroinvertebrates were collected from the cascade-pond system. Each of pond was calculated using macroinvertebrate indices namely Singscore and The Shannon Diversity Index. Nine parameters of water physics-chemistry were also collected from each pond and calculated based on The National Sanitation Foundation - Water Quality Index. The highest percentage of impervious cover is located in the upper of catchment and simultaneously reduce the percentage downward. The impervious cover affects the pattern of freshwater biodiversity and water quality the of cascade-pond system. The most diverse and highest score of aquatic organism was found at Salam sub-catchment that located in the lower part of UI catchment. Integrated assessment of UI catchment area using GIS-based multiple criteria decision analysis shows that the term of “end-of-pipe” at cascade-pond system affecting the ecological status of each catchment.

Abstract
Java’s North Coast National Road also known as Jalur Pantura is a primary transportation corridor connecting Indonesian capital city of Jakarta and eastern part of Java Island. Interestingly, the road’s greenbelt is located in Karawang Regency planted with various trees. From its diameter breast height (DBH) and height, above ground biomass (ABG) from these trees were estimated and then compared with four vegetation indices namely NDVI, SAVI, EVI and tasseled cap extracted from SPOT-7 satellite image. Furthermore, this study used predicted ABG values to generate carbon stock and carbon absorption ability. In addition, data from daily vehicle traffic observation will be employed to predict carbon emission. Estimated vehicle carbon emission then compared with carbon absorption ability for each road segment to observe how big trees can store carbon emission from vehicle. The information of carbon balance in each road segment, in form of comparison between carbon absorption ability with vehicle carbon emission, can be useful for road authority to increase vegetation especially in the areas of low carbon absorption.

Selfies Save Lives (Digital Strategies for Flood Response in Indonesia)
Authors: Fadmastuti M. 
Published: November 2019

Abstract
Flooding is very serious problem for cities in Asia; according to Dartmouth Flood Observatory, of the 20 megacities in East and Southeast Asia, 14 are sitting on river deltas and 18 have experienced major flood events in the past decade. In Indonesia, there are millions people exposed to flooding conditions during the monsoon season. There are also millions of residents who are connected to the internet, and one another, through their mobile devices. During flood situations, Indonesians are especially active on the social media; they share crucial information with each other through social media and instant messaging platforms. By sharing local information about their neighbourhood during the flood, others use this real-time information as to make decisions, reduce risk, and improve safety.
Though the local government has received some support from NGOs, private companies, and other agencies in terms of collecting information from the field during disaster events, this information is usually not well-integrated with their operational system, which can cause problems during emergency situation. By beginning from the chaotic reality experienced by residents and first responders during flood events, PetaBencana.id team created a design brief for their platform that made sure it would easily collect disaster reports from social media and integrate with real-time updates from governmental agencies. In the same time, the platform was designed to support peer-to-peer sharing and to democratize decision support by allowing residents with internet access to freely use the platform. PetaBencana.id also runs on free and open source software, which is a key to maintain public transparency and make the project sustainable.

Published: November 2019

Abstract
As a science and a subject in school, geography is considered as having a major role to play in fostering spatial thinking. In the context of preparing for an educational reform transferring from content-based to competency-based approach in Vietnam now, spatial thinking is identified as one of the prominent competencies that geography can promote. However, there has been no research on spatial thinking in the country so far. Therefore, this paper aims at reviewing spatial thinking in geography textbooks from grade 6 to grade 9 in Vietnam for the reason that geography is taught as a separate and compulsory subject in secondary and high school. We adapt the Taxonomy of Spatial Thinking proposed by Jo and Bednarz (2009) and then simplified by Scholz et al. (2014) to evaluate spatial thinking in three aspects: the concepts of spatial, tools of representation and processes of reasoning in questions in textbooks. The findings show that the majority of questions in textbooks are non-spatial thinking. The research gives suggestions for textbook authors in Vietnam to take three dimensions of spatial thinking into account in the future geography curriculum reform. Besides, it recommends teachers to consider to foster not only spatial thinking but also effective questioning in their teaching.

Published: November 2019

Abstract
The availability of instructional materials which present geographic perspectives is very important in resulting more effective learning of geography. It is completed with factual and conceptual knowledge that are functioned not only as informative sources, but also as organized instructional materials spatially and ecologically. The purpose of this research is to develop a model of geographic instructional materials based on the spatial-ecological perspectives. In order to develop the product, the research design used was the modified model of Borg and Gall design (2006). In the design, there were eight steps implemented to develop the product, namely: need analysis, planning, developing preliminary form of product, preliminary field testing, main product revision, implementing field testing, revision of product, and the final product revision. The subjects of the research were students of Senior High School-SMA10 Malang, Indonesia, and the research validator was a doctor of geography education. The data were collected by in-depth interview and questionnaire. In-depth interview was used to collect data from expert validators, while the questioner used to collect data from the students. The data from expert validation were used for the improvement steps of the model of geographic instructional materials based on the Spatial-Ecological perspectives. Meanwhile, the data from the students were used to determine the feasibility of the produced model. The data were analyzed descriptively and statistically. The results of this research were instructional materials developed based on the Eco-Spatial perspectives. There are six steps as a guide in developing the instructional materials. The sixth steps are: (1) determining the topics of discussion, (2) presenting the location of the phenomenon or object that occurs with maps, (3) presenting an argument of why the phenomenon occurred at the location, (4) presenting an explanations of life forms with the phenomena that occur, (5) presenting an explanation of the natural environment (ecosystem) to the phenomena that occur, (6) presenting an explanation of human life to the phenomena that occur. The results of the field testing show that the average score of the six development steps is 86.45%. Therefore, the instructional materials developed based on the Eco-Spatial perspectives were feasible to be used as reference in composing the geographical instructional materials.

Abstract
Aims of this paper was to find out the improvement of learning activities and collaboration in geography learning in the “dynamics of the atmosphere and its effects on life” topic through the application of EXO-OLO Task learning model. This learning model was developed in the author's dissertation research and based on cognitive and constructivist learning theory. It is also included in collaborative learning model. The type of the research is quasi experimental research. The populations of the study are students of grade tenth of Universitas Negeri Padang Laboratory High School. The experimental class and the control class were selected by simpel random sampling techniques. The treatment in the experimental class (XA) is using the EXO-OLO Task learning model, while in the control class (XB) using the common method which is used by teachers. The data is collected by using observation sheet of student’s learning and collaborative activities as well as student’s daily test (UH). The observation sheet has been validated by the experts. The data analysis of student’s learning and collaborative activities uses descriptive technique. In addition, the ‘t’ test is used to get to know the differences of learning outcomes between experiment class and control class. The result shows that there is an improvement in the quality of learning activities and student’s collaboration using the EXO-OLO Task learning model. This is proved by the increasing of the number of students who got three in learning activities and collaboration after four meetings. The quality of student’s learning activites increases as expected. The "t" test results show the differences between experimental class and control class learning outcomes proved by significance values. Based on the results of this study, the authors propose the teachers to use EXO-OLO Task learning model in geography learning to improve learning activities and collaboration.
