AbstractKawasan Taman Nasional Gunung Merapi (TNGM) memiliki ragam potensi keunikan keanekaragaman hayati, alam, budaya dan sosial ekonomi, sehingga keberadaan kawasan ini penting dalam menciptakan hubungan yang berkelanjutan antara manusia dan lingkungan alam. Ancaman akan kelestarian TNGM salah satunya datang dari kegiatan perambahan yang dilakukan oleh manusia. Penelitian ini bertujuan untuk menyusun peta tingkat potensi perambahan di TNGM dengan menggnakan pemodelan spasial berbasis Sistem Informasi Geografis (SIG). Pengetahuan tentang tingkat potensi perambahan tersebut dapat dimanfaatkan untuk mengetahui distribusi wilayah yang perlu disarankan untuk tindakan pengawasan. Pemodelan potensi ancaman perambahan disusun berdasarkan parameter ketinggian tempat, kemiringan lereng, jarak dari jaringan jalan, jarak dari jaringan sungai, jarak dari penggunaan lahan, dan jarak dari permukiman. Proses analisis yang digunakan adalah analisis tumpang susun dengan menggunakan metode kuantitatif berjenjang tertimbang. Hasil pemetaan potensi ancaman kemudian diintegrasikan dengan peta zonasi kawasan untuk menghasilkan rekomendasi tindakan pengawasan. Berdasarkan peta potensi ancaman diketahui bahwa bagian selatan dari daerah kajian memiliki tingkat ancaman yang paling tinggi, yang mana merupakan daerah di sekitar batas TNGM. Analisis rekomendasi tindakan pengawasan menunjukkan bahwa terdapat 1.194,71 hektar (58.35%) dari daerah kajian disarankan untuk diawasi. Daerah tersebut memiliki nilai potensi ancaman perambahan yang relatif tinggi dan termasuk dalam Zona Inti. Tepatnya berada dekat dengan batas kawasan yang kemungkinan besar terpengaruh oleh aktivitas masyarakat.Kata kunci: TNGM, Potensi Ancaman Perambahan, Sistem Informasi Geografis, Pemodelan Spasial. Mount Merapi National Park (TNGM) has a variety of potential uniqueness of biodiversity, nature, culture and socio-economic. The existence of this region is critical in creating sustainable relationships between humans and their natural environment. One of the threats to TNGM sustainability comes from encroachment activities carried out by humans. This study aims to perform spatial modeling by utilizing Geographic Information System to produce potential encroachment level map and uncover the areas that need monitoring. There are six parameters used to develop an encroachment threat model, namely elevation, slope, distance from the road, distance from the hydrological network, distance from land use, and distance from the settlement. Overlay analysis was implemented using a quantitative weighted scoring method. The result is then integrated with the TNGM zonation map to produce recommendations for supervision actions. The map of the potential level of encroachment threat show there are five classes of threat varying from high to low. The high-threat spatial arrangement dominates the southern area which is around the TNGM boundary. Recommendation analysis of supervisory actions shows that there are 1194.71 hectares (58.35%) of the study area recommended being monitored. Those were the region that both have a relatively high potential threat of encroachment and settled in the Core Zone. Precisely located near the boundaries of the area which are commonly affected by community activities.Key words: TNGM, Potential encroachment threat, Geographic Information System, Spatial modelling.

Abstract. Waterlogging as a perennial problem is deep rooted on the urban fabrics of English Bazar Municipality. The present study pertains to vulnerability and risk assessment of flood and waterlogging susceptible areas in a micro or local scale, based on an integrated Analytic Hierarchy Process-Geographic information System (AHP-GIS) category model. For this purpose, a multi-criteria assessment of natural, quasi-natural and man-made factors have been performed. Criterion includes six parameters namely elevation, slope, soil, flow accumulation, land use land cover, density of digitized drain network which are responsible to initiate the waterlogged condition within municipality premises. The weights of all criterion are computed by pair wise comparison decision matrix (AHP). According to their weightage, information of different parameters are superimposed for a final weighted overlay analysis following a spatial modelling, under ArcGIS 10.5 platform to delineate the flood and water logging susceptible zones. The result obtained from this study indicate 11.45 %, 3.05 % and 85.49 % area of municipality corresponds with highly vulnerable, low and moderately vulnerable respectively. The major finding in the study reveals that unplanned urban expansion in the hazardous low-lying area by filling up of wetlands and depressions in association with inadequate drainage gravity provisions in the newly built-up wards (3, 23, 24 and 25) are noteworthy for resultant waterlogging condition. The present paper also aims to suggest long-term mitigation measures to be well integrated for arriving at a well drafted and implementable comprehensive drainage plan of English Bazar municipality.

This research addresses the phenomenon of varying bicycle friendliness in urban areas and considers which elements are necessary to design a city in a bike-friendly manner. It aims to provide a deeper understanding of the term bikeability, in relation to the established term walkability, and methods to create models that measure the degree of bikeability in urban areas. We explain different established models and compare their computational bases. The focus of this paper is to define a computational methodology built within a Geographic Information System (GIS) and a subsequent evaluation based on an investigation area in Munich, Germany. We introduce a bikeability index for specific investigation areas and geovisualize four selected factors of this index. The resulting map views show the road segments of the traffic network where the conditions for biking are adequate, but also those segments which need to be improved.

Geographic Environment

Indonesia is a massive archipelago of 1.919.400 km², containing roads that span at 542.000 km across various terrain conditions. This diverse geographic environment is a challenge to road constructions and repairs across the country, which has lead to disruption in public service and traffic accidents each year. We propose the Geographic Information System for Mapping and Complaint of Damaged Roads, a solution which can provide users a digital interface to report damaged roads to the transportation department in their area. This research uses Google Maps API to digitize and make a complaint about damaged roads. The result of this research is an android application for the users and a website application for the road managers. The android application is used by the users to make complaints of damaged roads. The web application is used by road managers to draw the road on Google Maps using polyline feature. With this our goal is to systematize the handling of damaged roads information, leading to faster service times and hopefully help reduce the level of traffic accidents in Indonesia.

ABSTRACT Geographic Information System (GIS) is an indispensable software tool in forest planning. In forestry transportation, GIS can manage the data on the road network and solve some problems in transportation, such as route planning. Therefore, the aim of this study was to determine the pattern of the road network and define transport routes using GIS technology. The present research was conducted in a forestry company in the state of Minas Gerais, Brazil. The criteria used to classify the pattern of forest roads were horizontal and vertical geometry, and pavement type. In order to determine transport routes, a data Analysis Model Network was created in ArcGIS using an Extension Network Analyst, allowing finding a route shorter in distance and faster. The results showed a predominance of horizontal geometry classes average (3) and bad (4), indicating presence of winding roads. In the case of vertical geometry criterion, the class of highly mountainous relief (4) possessed the greatest extent of roads. Regarding the type of pavement, the occurrence of secondary coating was higher (75%), followed by primary coating (20%) and asphalt pavement (5%). The best route was the one that allowed the transport vehicle travel in a higher specific speed as a function of road pattern found in the study.

Eucheuma Cottonii

The Tidung Island in Kepulauan Seribu District is a tourist destination for both domestic and foreign tourists. However, not all residents of Tidung Island work in the tourism sector. Some work as fishermen. In 2016, local governments developed seaweed cultivation (Eucheuma cottonii) which made some residents switched jobs to seaweed farmers. This study aims to determine which areas are oseanographically appropriate and have potential as a seaweed cultivation development area. The research method use variables of oceanography in the form of substrate type, protected, temperature, depth, current speed, salinity, and pH. The cultivation variable consists of labor, technology, and management. To determine the direction of development, tourism variables which being used consist of distance from tourist sites and the number of supporting facilities. The analysis uses Geographic Information System (GIS) technique and scoring method. The results show in the northern Tidung Island waters are suitable for seaweed cultivation from the point of view of oceanography. However, the development potential is only in U2 segment, which is support by high production quantities, long distance from tourism object, and low number of accommodation makes it potentially to be developed area.
