Abstract

Peningkatan kepadatan penduduk dan permukiman berbanding lurus terhadap kerentanan sosial. Penelitian ini mengintegrasikan teknologi geoinformasi dalam penilaian kerentanan sosial secara spasial dan temporal dengan skala detail. Tujuan dari penelitian ini untuk menganalisis tingkat kerentanan sosial secara spasial setiap unit rumah pada pagi, siang, sore, dan malam hari. Metode pengolahan data dengan teknik sensus untuk mendapatkan informasi anggota penghuni rumah. Interpretasi citra Quickbird dilakukan untuk menganalisis kenampakan tapak bangunan. Bobot dari tiap parameter kerentanan sosial menggunakan metode Analitycal Hierarchy Process (AHP). Dinamika spasial dan temporal kerentanan sosial terhadap gempa bumi di Dusun Joho didukung dengan hasil analisis data berupa nilai kerentanan tertinggi terdapat pada parameter penduduk lansia sebesar 41% dan parameter kerentanan sosial terendah adalah kepadatan penduduk sebesar 7%. Di antara 354 total bangunan, 126 rumah terklasifikasikan dalam tingkat kerentanan sosial rendah (36%) pada pagi dan siang hari. Kerentanan sosial sedang (39%) pada sore dan malam hari sebanyak 138 bangunan dan kerentanan sosial tinggi (51%) pada sore dan malam hari sebanyak 179 rumah.

Abstract

Presidential Regulation Number 21 of 2019 concerning the National Action Plan for Mercury Reduction and Elimination (RAN-PPM) became the strategy for reduction and elimination of Mercury, then later revealed in the Regional Action Plan for Mercury Reduction and Elimination (RAD-PPM). According to it, a comprehensive monitoring method is urgently needed, neither only related to the elimination of mercury in the ASGM sector, but also for regional development potential. This research is a Research and Development research, which is a type of research that aims to develop applications, which are used as a tool for decision making-a Decision Support System (DSS). Using a descriptive qualitative method, to analyse related documents, interviews with related actors, and calculate System Usability Scale to analyse and see the usability and the level of user acceptance to the WebGIS. The case study is the development and preparation of a WebGIS related to the ASGM sector in Kokap, Kulon Progo. The result of the study shows that an information system with geospatial-based analysis could facilitate data integration, implementation and monitoring of the regulation of mercury elimination, especially in the ASGM sector. As a result of the WebGIS System Usability Scale for Small-Scale Gold Mining in Kulon Progo Regency, it is included in the category of applications that can be accepted by users and is quite appropriate. Nevertheless, synergy and cooperation between various agencies are necessary. Moreover, the data related to socio-economic which is an important information system for regional development can also be mapped in a GIS.

Abstract

As an essential non timber wood product in Indonesia, optimization of cajuput (Melaleuca cajuputi) development can be determined through land suitability studies. BKPH Yogyakarta is a government organisation that managing forest area in Daerah Istimewa Yogyakarta Province. Playen Forest Area is one of BKPH Yogyakarta managing area that used for developing cajuputi. Geographic Information System (GIS) is one of the tools that can be used to handle spatial data. The purpose of this study was to determine the distribution of land suitability classes for cajuput in BDH Playen. A parametric approach was used to determine the land suitability class. Two methods in the parametric approach used are the storie and root square land index. From the research, the land index value of the stories equation tends to be smaller than the root square equation. The results of the root square method are considered more relevant to the conditions in the field, where the cajuputi stands in BDH Playen can still produce commercially. There are 3 (three) land suitability classes for cajuput in BDH Playen, namely marginally suaitable (S3), currently not suitable (N1) and permanently not suitable N2. The broad percentage of the total land suitability classes S3, N1 and N2 is 61.7%, 16% and 22.3% respectively. Rainfall becomes a limiting factor in all three classes of land suitability. In the land suitability class N1 and N2 there are several limiting factors, namely the problem of soil tends to be alkaline, shallow soil depth, drainage is hampered.
