Abstract

Telah dilakukan penelitian air tanah di sekitar tempat pembuangan akhir (TPA) sampah Bantar Gebang Bekasi menggunakan metode isotop alam (18O, 2H dan 3H) dan dilengkapi data hidrokimia. Penelitian ini dilakukan dengan mengambil sejumlah sampel air lindi, air permukaan dan air tanah di sekitar TPA dengan tujuan untuk melihat sejauh mana pengaruh sanitary landfill terhadap air tanah di sekitarya. Hasil analisis isotop alam menunjukkan bahwa sebagian besar air tanah dangkal telah mengalami kontaminasi oleh zat pencemar yang berasal dari TPA yang sebarannya telah mencapai kira-kira 1 km dari lokasi TPA. Hasil ini didukung dengan data hidrokimia khususnya nitrat yang memperlihatkan kecenderungan yang hampir sama. Sedangkan air tanah akuifer dalam (>40 meter) tidak memperlihatkan adanya pengaruh dari zat pencemar yang berasal dari area TPA.

Abstract

At the present time, water scarcity in Bandung Basin has reached its critical point, marked with springs that stop discharging and lowering water table. The same condition can be seen on river water that heavily exposed by industrial waste along the river. Through environmental isotopes (2H, 18O and 14C) approach, the condition of deep and shallow groundwater wells alongside the river can be known. This research was conducted by taking some samples of shallow groundwater, deep groundwater and river water (Citarum, Cikapundung, Cikeruh and Citarik). The amount of water sample needed for 2H and 18O isotopes analysis was 20 ml, whereas for 14C isotope analysis, 60 liters of water sample needed to extract into BaCl­3 precipitation. Based on isotopes 2H, 18O and graphic 2H vs 18O data show that there are three of resident groundwater (shallow groundwater) which its groundwater have been mixing by river water. Whereas the result of isotope 14C, does not show inter relation, either by shallow groundwater or river water. From iso-age contour, it could be concluded that the dynamics pattern of deep groundwater show movement derived from north and south mountains to north-west direction (Cimahi and Leuwigajah). These locations are industrial area with very high groundwater exploitation.

Abstract

Groundwater age study has been carried out on mud eruption area in Sidoarjo using natural isotopes. The study was done in 2007 and 2009 by analyzing water samples from mud eruption area. The aim of the study was to identify water characteristics which seeped out from the mud eruption area. Origins of the water can be fossil water, groundwater, or sea water. The 18O, 2H, and d2H data, which were plotted together with d18O data of the water samples of 2007 (LUSI-1 and LUSI-2), showed that water from the center of mud eruption area had interacted with magmatic materials. Whereas, the water from LUSI-3 location which was collected about 300 m distance from the center of mud eruption area had an age of more than 40,000 years, which contained 13C, 18O, and 2H of 1.58o/oo, 5.28o/oo, and -17.5o/oo respectively. This matter indicated that the water was sea water fossil which interacted with magmatic materials. The water in LUSI-4 location had an age of 18,408 years, which contained 13C, 18O, and 2H of -10.5o/oo, 7.68o/oo, and -35.3o/oo respectively. These data indicated that the water was fresh water, which was not mixed with water from mud. The water age from LUSI-5 location was 14,237 years, and contained 13C, 18O, and 2H of -3.00o/oo, -0.25o/oo, and -21.1o/oo respectively. These data showed that the water was partially originated from the groundwater and dominated by mud water. The water age at MVKA location was 14,355 years, and contained 13C, 18O, and 2H of 2o/oo, 2.61o/oo, and -6.6o/oo respectively. This water was estimated as a mixture of mud water and intruded sea water. Plots of 18O, 2H, d2H and d18O, 14C data of water samples of 2009 showed that the water was dominated by groundwater, but the water from LUSI-11 sample was indicated as sea water.

Abstract

The presence of spring in Dompu Regency is an asset for the sustainability of natural resources and cultural resources in the surrounding area. This study aims to determine the conservation efforts of springs in the Dompu site area based on local wisdom and its current impact. This research utilizes ecological, isotope, and hydrochemical approaches. Data was collected through field observations and water sampling at the Riwo Spring. The data were analyzed using ecological, isotope, and hydrochemical approaches to samples of water followed by qualitative descriptive analysis. Based on the results of isotope and hydrochemical studies on the Riwo spring, it showed that the spring has good water quality, which means it is still suitable for consumption and this spring is young, so the balance of the surrounding environment is very important to maintain. The sustainability of springs is sought by applying local wisdom, one of which is leka dana. Leka dana can be used to determine policies for environmental conservation policy, conservation of forest catchment areas, and sustainable springs in Dompu Regency. Based on the results of the isotope and hydrochemical study result, it is recommended that in Riwo Spring areas and the surrounding forest, which served as recharge areas, should not be cleared for plantations or settlements. These recharge areas should be preserved and if necessary reforested. Keywords: spring conservation, archeology, natural isotopes, hydrochemistry, local wisdom
