ANALISA PENGARUH PENURUNAN TANAH LAND SUBSIDENCE TERHADAP NILAI TANAH STUDI KASUS KECAMATAN PENJARINGAN - JAKARTA UTARA

ANALYSE OF LAND SUBSIDENCE EFFECT TOWARD LAND VALUE CASE STUDY SUBDISTRICT PENJARINGAN NORTH JAKARTA

ABSTRAK

Penurunan tanah land subsidence merupakan suatu fenomena alam yang banyak terjadi di kota kota besar yang berlokasi di sekitar pantai atau dataran alluvial seperti Jakarta Semarang dan Surabaya. Penurunan tanah berhubungan dengan fenomena fenomena alam dan lingkungan yang dibangun manuasia seperti terjadinya banjir intrusi air laut perubahan aliran sungai dan penataan konstruksi bangunan yang nota bene bersifat destruktif. Oleh karena itu perlu adanya penelitian untuk mengetahui apakah penurunan tanah dapat mempengaruhi nilai tanah atau tidak. Data yang diperlukan dalam penelitian ini antara lain data spasial yaitu Peta Zona Nilai Tanah dan Peta Geologi Lambar Jakarta dan Kepulauan Seribu. Sedangkan data nonspasial yaitu data Nilai Indikasi Rata-Rata dan grid penurunan tanah. Data tersebut diolah menggunakan software ArcView. Hasil dari penelitian ini menunjukkan bahwa pada tahun 1997-1999 korelasi antara penurunan tanah dengan perubahan nilai tanah sebesar 0164. Sedangkan pada tahun 1999-2000 sebesar 0318 dan pada tahun 2000-2001 sebesar 0108. Hal ini menunjukkan bahwa korelasi antara penurunan tanah dan perubahan nilai tanah adalah sangat lemah atau dianggap tidak ada.


ABSTRACT

Land subsidence is one effect of natural phenomenon that happens mostly in big cities that lie on seashore or alluvial land such as Jakarta Semarang and Surabaya. Land subsidence concerns with natural phenomenon and environment that human have been built such as flooding sea water intrusion river flow alteration and structuring of building construction that have destructive characteristic. Therefore observation is required to understand whether land subsidence can affect land value or not. Required data for this observation consist of spatial data and non spatial data. The spatial data consist of Land Value Zone Map Geology Map of Lambar Jakarta and Seribu Archipelago. While the non spatial data consist of Average Indication and Land Subsidence Grid Value. Those data then would be processed by software was named ArcView. The result of this observation shows that during 1997- 1999 periods the correlation between land subsidence and land value alteration 0.164. Otherwise during 1999-2000 periods the correlation value is 0.318 and during 2000-2001 periods the correlation value is 0.108. These results show that correlation between land subsidence and land value alteration is very insignificant or ignored.
