Abstract

The recent advances of remote sensing technology development can support government needs including cadastral related purposes. One of the purposes is to supply geospatial data especially land parcel maps for land and tax value inventory. This research tries to evaluate the utilization of Quickbird Satellite image for updating land and building (PBB-P2) block maps in Bantul Regency, Yogyakarta Province of Indonesia. The image was recorded in 2014 with resolution of 0.6 meter and has been ortho-rectified. Evaluation is conducted by analyzing the utilization of the image as the base map for deriving land parcel maps according to the Decree of Tax Director General number: KEP-533/PJ/2000. The process was firstly done by digitizing land parcel boundaries on Quickbird image to produce block maps. The process was done by the community through participatory mapping. The resulting block maps then were compared with land registration map from National Land Agency. The evaluation was focused on the accuracy of land parcel position as well as the resulting land areas. For this purpose the land registration map is regarded as the reference data. By focusing on the 51 sample data in Triharjo Village, statistical test was conducted to evaluate the accuracy of the resulting areas of the digitized land parcel map. The results show that 47 samples comply with a tolerance requirement of 10% according to the Decree of Tax Directorate number KEP-533/PJ/2000’. In addition, the t-test analysis with a significant level of 5% indicates that there is no significant difference of area between the digitized land parcel data with land registration map. Based on the results, it is concluded that ortho-rectified QuickBird image is sufficient for producing of land and building tax (PBB-P2) block maps.

Abstract

The Regulation of Bupati Bantul Number 35/2013 regulates the establishment of networked minimarket (mini market berjejaring) in Bantul Regency. This study was conducted to assess the suitability between the regulation with the real condition by emphasizing the spatial aspects after 5 years of the implementation of the regulation. This study concerns with the criteria in the regulation about the distance of the mini markets from the traditional markets and the class of the road. The data for cunducting the spatial analysis include road vector data, administrative boundaries, locations of traditional market and networked minimarket, attribute data for networked minimarket, and satellite images of Bantul Regency. The data then was analyzed using proximity and network analysis to know suitability of networked minimarket locations with the regulation. Proximity analysis was done using buffer operation, meanwhile network analysis was done using operation of OD Cost Matrix. Result obtained from the proximity analysis of the overall parameters show that there is only one minimarket in accordance with the regulation. In the other hand, , if the network analysis is included, then the number of minimarkets that comply with the regulation increase to three minimarkets. To conclude, most of the locations of the netwoked minimarkets in Bantul do not comply with the Bupati Bantul Regulation Number 35/2013.

Abstract

Gunungkidul Regency is one of five regencies in Yogyakarta Province which is rich of natural tourism destination objects. Each tourism object has its own potential and characteristic that distinguishes one with other tourism objects. However, the tourism potency have not been exposed to public properly, and the local government has not sufficiently use the data of visitors as the basis for planning and development of tourism objects in Gunungkidul Regency. This research tries to evaluate the use of BIG DATA, especially social media data, to analyze the tourism potency based on the public opinions and visits. For this purpose, Instagram data was utilized as the main data for the analysis. The data was collected between December 18, 2017 to February 3, 2018 using Instagram API. The data then was pre-processed to clear or filter the duplication data, to filter the data based on selective location or study area namely Gunungkidul Regency, as well as to filter the data which match with the topic of the research namely “tourism”. Some analysis then were conducted, namely spatial analysis, statistical analysis, and caption analysis. The spatial and statistical analysis were aimed to find spatial pattern of tourists visits at several locations in the form of spatial density of each tourism destinations with respect to temporal aspect. Analysis of captions is done by filtering Instagram data by using some keywords that can indicate tourism potency. Data was visualized using Carto Builder. Results show that some effort is needed to utilize the Instagram data for this purpose. The data is efficient and effective to be used to visualize spatial-temporal pattern of visitors at tourism destinations, as well as to understand tourism destinations objects potency in Gunungkidul Regency. However, this analysis cannot be done in realtime due to a limitation in collecting data from Instagram API.

Abstract

The dynamics of the Indonesian population has increased causing the need for cadastral objects to increase. 2D and 3D cadastral objects change over time. Cadastral objects have spatial and juridical data changes every day. These changes can be caused by the transfer of rights, changes of rights, split and merging cadastral objects. Changes are recorded and stored as a history of cadastral objects (4-dimensional cadastre). Historical data on cadastral objects can be categorized as one of the big data in the cadastre sector, based on the frequency of recording data. The data can be used to track changes in cadastral objects so that they can avoid disputes. Spatial data in this case is very vulnerable data to cause disputes if the shape, position and size do not match the conditions in the field, and need special attention in integrating with the juridical data. This paper aims to identify methods for storing spatial data of 4D cadastral objects that are suitable for Indonesia. The importance of storing cadastral objects and their history causes researchers and cadastre experts in the world to formulate international standards in managing spatial and juridical data along with a history of cadastral objects (4D cadastre). LADM is an international standard conceptual model (ISO 19152) which can show the legacy of a cadastral object expressed in RRR (Rights, Restriction and Responsibility). In LADM, there is a VersionedObject class that represents various versions or a history of spatial units, object registration, owner and administration. Several studies conducted by researchers in the world were compared in this paper to find methods for applying LADM and VersionedObject classes. That methods were implemented in this paper to design a database of spatio-temporal 4D cadastre. Finally a prototype of spatial-temporal database will be produced to manage 4D cadastral objects.

Abstract

Land is a resource with limited availability, but has an ever-increasing demand. Land Consolidation is a realignment activity which can be an alternative in planning a regional development. Land Consolidation in Gadingsari Village is a Bantul Regency government program implemented in 2017 located in Nanggulan, Patihan and Wonoroto Villages involving 200 land parcels , with 172 participants for land consolidation and 111,467 m2 of land. Land Consolidation produces land that has good accessibility and regularity of land parcels so it may triggers an increase in land value. An increase in land value can be estimated by modeling the land value before and after land consolidation. One method that is often used in the modeling of land values is the multiple variable linear regression method. The method used in this study involves the price of land as the dependent variable and the independent variable, namely: (1) Road Class; (2) Distance of land parcels to the Economic Center; (3) Distance of land parcels to the Village Government; (4) Distance between land parcels to the tourist site; (5) Distance of land parcels to Health Facilities; (6) Area; (7) Distance of parcels to Main roads; (8) Distance between land parcels of land to the beach; and (9) Land Use. The model formed is then used to calculate the estimated value of land prices before and after the implementation of land consolidation. The estimated value of land produced by the land value model prior to land consolidation ranges from Rp. 11,000 to Rp. 370,000. While the estimated land value for the land value model after land consolidation ranges from Rp. 21,000 to Rp. 605,000.

Abstract

Kabupaten Purworejo terletak pada jalur lintas selatan di wilayah Jawa Tengah yang menghubungkan Yogyakarta dengan kota-kota lain di wilayah selatan Jawa Tengah seperti Kutoarjo, Kebumen, Purwokerto, serta kota-kota lainnya. Letak Kabupaten Purworejo yang strategis ini berdampak pada dinamika sosial, ekonomi, dan kependudukan, khususnya pertumbuhan wilayah. Berdasarkan fenomena tersebut, penelitian ini bertujuan untuk mengetahui perubahan penggunaan lahan yang terjadi di Kabupaten Purworejo, serta kesesuaiannya dengan Rencana Tata Ruang Wilayah (RTRW) tahun 2011-2031. Metode yang digunakan adalah pendekatan analisis geospasial untuk melakukan analisis spasial-temporal perubahan spasial penggunaan lahan dari tahun 2008 dan 2013. Hasil analisis perubahan spasial ini kemudian dikorelasiakan dengan  peta RTRW Kabupaten Purworejo tahun 2011-2031 untuk mengetahui tingkat kesesuaian pengunaan lahan di Kabupaten Purworejo terhadap RTRW. Hasil penelitian menunjukkan bahwa dalam waktu 5 tahun dari tahun 2008 sampai dengan 2013 terjadi perubahan penggunaan lahan sebesar 0,1%. Perubahan luas penggunaan lahan terbesar terjadi di Kecamatan Grabag dengan persentase 0,71%, sedangkan Kecamatan Ngobol, Bener, Gebang, dan Loano bisa dikatakan tidak mengalami perubahan penggunaan lahan. Ditinjau dari kesesuaian penggunaan lahan terhadap RTRW, maka dapat diperoleh informasi bahwa tingkat kesesuaian penggunaan lahan pada tahun 2013 adalah sekitar 62,21%. Kecamatan Kutoarjo dengan persentase 93,34% merupakan kecamatan dengan persentase penggunaan lahan terbesar sesuai peruntukannya. Sedangkan Kecamatan Bagelen dengan persentase 38,40% merupakan kecamatan dengan persentase penggunaan lahan terkecil sesuai peruntukannya.

Abstract

Sebagai ibukota Kabupaten Banyumas, pertumbungan dan perkembangan Kota Purwokerto cukup pesat dalam beberapa dekade terakhir. Pengalihan fungsi lahan menjadi permukiman dan bangunan untuk fungsi lain menjadi salah satu akibat dari adanya pembangunan di Kota Purwokerto. Pertambahan jumlah penduduk di Kota Purwokerto juga mengakibatkan pengalihan fungsi lahan menjadi permukiman semakin tinggi. Hal ini menyebabkan terjadinya penurunan ketersediaan Ruang Terbuka Hijau (RTH) di Kota Purwokerto. Oleh karena itu, penelitian ini bermaksud untuk menganalisis ketersediaan dan kecukupan RTH di Kota Purwokerto. Untuk itu, pemetaan dan pengklasifikasian RTH dilakukan menggunakan teknologi penginderaan jauh dengan data citra satelit SPOT 6, metode Object Based Image Analysis (OBIA) serta interpretasi visual. Pengukuran luas RTH dan analisis spasial dilakukan menggunakan Sistem Informasi Geografis (SIG). Analisis ketersediaan dan kecukupan RTH terhadap jumlah penduduk dan kebutuhan oksigen mengacu pada UU No. 26 Tahun 2007 dan Permen PU No. 05/PRT/M/08. Analisis ini dilakukan untuk tahun 2013, 2019, dan 2020. Perhitungan kebutuhan oksigen dihitung menggunakan Metode Gerakis. Pemetaan dan perhitungan luas RTH dilakukan dengan perangkat lunak eCognition Developer dan SIG. Perhitungan luas kebutuhan RTH terhadap jumlah penduduk dan kebutuhan oksigen dilakukan dengan perangkat lunak SPSS Statistics 26. Hasil penelitian menunjukkan bahwa luas ketersediaan RTH di Kota Purwokerto sudah memenuhi standar luas kebutuhan RTH terhadap jumlah penduduk. Namun, luas ketersediaan RTH tidak memenuhi luas kebutuhan RTH terhadap kebutuhan oksigen. Luas ketersediaan RTH privat sudah memenuhi ketentuan 10% dari luas wilayah Kota Purwokerto berdasarkan UU No. 26 Tahun 2007. Tetapi, luas ketersediaan RTH publik tidak memenuhi ketentuan 20% dari luas wilayah kota.
