Every household gets rice and egg in the equivalent of IDR 110,000 per month. In Kulon Progo Regency, the number of recipients amounted to around 53,000 households. Rice and eggs to be distributed should come from local farmers and breeders. The delivery is conducted by e-Warong, a community-owned small kiosk. However, the location of rice supplier and e-Warong have not been known. This paper aims to describe the mapping of these parties and analyze their spatial implication. The following geospatial data: administrative boundary, road network, and digital elevation model (DEM). List of recipients, e-Warong and Gapoktan were provided by the Social Agency of Kulon Progo Regency. Mobile Topographer apps were used to map the location of 13 rice suppliers, 111 e-Warongs, and parts of household recipients. Egg suppliers are not mapped because for each month each E-Warong can change suppliers, adjusting the availability of eggs. They were processed using spatial analysis operation. The result is maps of the distribution network and service area. Spatially and visually, the inequality of the distribution network is evident. This inequality is caused by distance and topography, factors that were not visible in the textual data currently in used. Where the E-Warong area in the northern part of the district is a plateau or hilly which makes mobility more difficult than E-Warong in the southern part which is a lowland. GIS has been used to create maps of the distribution network in visually attractive and spatially descriptive models.

Congestion that occurred in Yogyakarta, especially around Universitas Gadjah Mada is progressively increased. The cause of the increasing level of congestion is the lack information for traffic user about the congestion itself. Therefore, a media that can provide the congestion information digitally, easily accessible and interactive is required. Media information is in the form of a website that inform traffic congestion that occurs at traffic light around Universitas Gadjah Mada. Information on the level of traffic congestion was obtained by photographing directly at the location of the survey to according to pre-determined time. Then the data was inserted into a database, and the results were linked with the Google Maps API. In the end the map inside interactive website can be accessed by the user.

In order to accelerate the validation process, government-facilitated participatory mapping processes which have been endorsed by many local land offices. This study examines the applicability of participatory approaches in validating land boundaries for supporting land registration processes. Aerial photo-map was used as the base to plot land parcels, which later was used to produce a working map. Field surveys were conducted to verify land boundaries. The availability of participatory land parcel map was not only useful to accelerate land registration processes, but was also able to serve as a visual tool which helps anticipating boundary disputes and land development at village level. The results of the study shown that participatory map contributed in improving quality of land registration map but suffers level of detailing in respect to actual shape and area of land boundaries</em>

One of Green Campus concepts is the green behaviour by giving information and inviting citizens to use energy, water and paper efficiently and giving education to citizens about environmental issues. One of the examples in energy efficiency practice is car-free streets. Energy consumption can be shown by number of vehicles and number of vehicles can be shown by sound level comparison or sound level mapping. Sound level mapping is a graphic representation of the sound level distribution existing in a given region, for a defined period. The higher sound level indicates more vehicle pass through an area. Number of vehicles and limited street capacities create traffic jam frequently. During a traffic jam, vehicle burn fuel but not moving and cause bad effect to environment. Sound level mapping is needed to know how big the ef...

Meanwhile, on the other hand, community needs (as policy recipients) and government (as policy makers) are getting higher with actual and accurate data and information. Data and information users are increasingly demanding and critical in the current era of information disclosure.The National Land Agency (BPN) as the provider of land services has in such a way proceeded in its journey to accommodate the various demands of the people in the field of land. Utilization of information system technology developed BPN to provide better service to the community, among others through LOC, KKP and finally with the support of Internet technology that is KKP-Web. In the course of many successful demands fulfilled, but can not be denied there are still problems in the completion of mapping the plot of land as the most essential part in the construction of a good land database.SIGP raises opportunities with a participatory approach, where there are potential efeisiencies that need to be underlined. While on the other hand PGIS still leaves a challenge related to quality control and standard procedures.</em>

This paper evaluates the implementation of intelligent transportation system (ITS) in some Indonesian cities, i.e. Jakarta, Bandung, Surabaya, Yogyakarta, Solo and Denpasar. Applications of ITS in Indonesian cities are identified, i.e.: Area Traffic Control System (ATCS), traffic infrastructure, travel information, public transport, commercial vehicle, traffic information and e-ticketing system. The problems are then analysed, i.e.: financial support and human resources. It is suggested that these things to be taken into consideration when developing ITS system, i..e. sustainability, open system, user friendly, vendor support, reliability, feasibility, investment and high level of domestic content .

It enables city planner and manager to develop optimum plan based on location and its spatial dependencies. Geospatial information supports the most detailed level of planning up to individual parcel and building. It supports management of city affairs, such as building permit and taxation, efficiently. Further, it also enables better service deliveries to those who request. In order to performing these activities well, geocoded address must first be developed. This paper investigates status, issues and challenges in developing geocoded address in Indonesia. The following aspects were examined: regulations, availability, base data to develop geocoded address, actors, and applications. A case study on developing geocoded address for a segment of Jalan Kaliurang in Yogyakarta for urban area and Baturetno Village for rural area were presented. This paper found that although geocoded address is a vital element for many development activities, it is still undeveloped.

Sumber data untuk pembuatan DTM meliputi data titik tinggi dan/atau garis kontur yang dapat diperoleh dari pengukuran langsung di lapangan, konversi dari peta topografi, teknik fotogrammetri, INSAR dan LIDAR. DTM dibuat dengan menggunakan metode interpolasi tertentu. Tulisan ini, membahas perbandingan penggunaan tiga metode interpolasi yang berbeda, yaitu Inverse Distance Weighted (IDW), Spline, dan Triangular Irregular Network (TIN) untuk pembuatan DTM dengan data dari peta topografi skala besar. Peta topografi tersedia dalam skala 1:5000 yang dibuat dengan metode fotogrametri. Peta memiliki kerapatan kontur 2 meter dan ribuan titik tinggi yang tersebar di daerah studi dengan elevasi dan kelerengan yang bervariasi. Kontur dan titik tinggi digunakan untuk membuat DTM dengan tiga metode yang berbeda. Evaluasi dilakukan dengan analisis secara visual dan matematis pada daerah uji. Analisis visual dilakukan dengan mengamati adanya anomali lubang dan puncak yang terbentuk. Analisis secara matematis dilakukan dengan perhitungan RMS error beberapa titik sampel dengan tingkat kepercayaan 95%. Titik sampel diambil pada daerah datar, berbukit jarang dan berbukit rapat. Hasil akhir DTM disajikan dalam format raster untuk memudahkan proses evaluasi. Penggunaan metode TIN menghasilkan DTM dengan RMS error 1,54 meter, metode IDW menghasilkan RMS error 1,79 meter, dan 1,78 meter pada metode Spline. Evaluasi secara visual dan analisis matematis menunjukkan bahwa metode IDW baik digunakan pada daerah datar-rapat. Metode Spline baik digunakan pada daerah berbukit-rapat dan berbukit-jarang, sedangkan metode TIN baik digunakan pada daerah datar-jarang; peralihan-rapat, dan peralihan-jarang.

Local government activities with spatial components include, but are not limited to, spatial planning, land management, taxation, and the issue of building and site permits. A framework for governing spatially related activities needs to be formulated. An emerging concept of Spatially Enabled Government (SEG) is currently being developed, refined and implemented in many countries. SEG will increase efficiency, transparency and accountability of government activities. This paper will discuss the SEG concept, its prospects and challenges when implemented in the context of Indonesian local government.
