Dari proses diagenesis dan dekomposisi batuan, tanah yang terbentuk di Indonesia mempunyai sifat ekspansif yang sangat rentan menjadi pemicu gerakan tanah. Dari proses ini juga akan mempengaruhi kelimpahan mineral lempung beserta sifat-sifatnya. Mineral lempung yang menjadi penyusun sebuah tubuh tanah sangat mempengaruhi sifat tanah yang terbentuk, baik sifat kimia, sifat biologi, dan sifat fisik tanah. Mineral lempung yang menyusun dan terdapat pada tanah lunak atau tanah ekspansif mempunyai karakteristik pembawa sifat geoteknik dan geokimia yang dapat mempengaruhi apapun yang ada di atasnya. Kajian ini bertujuan mengetahui tipe dan sifat dari mineralogi lempung, serta implikasinya terhadap gerakan tanah.

Geographically DKI Jakarta Province is lowland, it caused Jakarta has high of flood hazard. This condition potentially result of high risk. Based on it, the aims of research is: 1). Making map of flood susceptibility in Special Capital Region of Jakarta area, based on geomorphology approach, and 2). Data inventory element at risk of flood. The method of data analysis used qualitative, based on interpretation satellite imagery data using elements of interpretation. Indicators used to result map of flood susceptibility are elevation, slope, and landform, using scoring and overlay technique. The result of research is flood susceptibility of low area is 13.613,40 ha, medium is 23.238,67 ha, and higt is 27.216,72 ha. Based on it, the majority of research area have hight of flood susceptibility. Based on spatial pattern, it showed that areas with high flood susceptibility are mostly located in the northern part of research area, and areas with the lowest flood susceptibility are majority in the southern part of researh area.

Akan tetapi, kondisi geografis Provinsi DKI Jakarta yang merupakan dataran rendah, mengakibatkan wilayah Jakarta memiliki ancaman tinggi terhadap bahaya banjir. Hal ini dapat berpotensi menghasilkan tingginya risiko kerugian terhadap bencana. Berdasarkan hal tersebut, tujuan dalam penelitian ini yaitu: 1) Membuat peta kerawanan banjir Provinsi DKI Jakarta berdasarkan pendekatan geomorfologi, dan 2). Melakukan inventarisasi elemen berisiko yang berpotensi terpapar banjir. Metode analisis data dalam penelitian ini menggunakan analisis kualitatif, karena berdasarkan teknik interpretasi data citra secara kualitatif yaitu menggunakan unsur-unsur interpretasi.

In case of Zero Delta Q application planning at the community level, a software is needed that can help classify and quantify the existing land cover class in area where the community is located. The purpose of this study is to look at the time needed and reliability of the i-Tree Canopy web-based software online in classifying and quantifying land cover classes on one of the sub-catchments in the Pesanggrahan River Basin. The land cover class is divided into six: trees, grasses / undergrowth plants, open area, water bodies, pavement / road and roof of the building. For comparison, an RBI map is used from the same area to see the extent of each class of land cover. Observation of each point requires an average time of 5.2 ± 1.0 seconds. The difference between direct sub-basin measurements using i-Tree Canopy and detailed analysis results from the RBI map is within the range of 0.41% or 0.36 Ha for each individual class of land cover. For a relatively small study area (under 100 ha) and when supported with reliable internet access, this web-based online software is sufficiently reliable in assisting the application planning process to support Zero Delta Q policy.","PeriodicalId":270402,"journal":{"name":"Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129259569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
