There are 4 (four) locations for the placement of Tax Volunteers, namely KPP Pratama Singaraja, KP2KP Negara, KP2KP Amlapura and Tax Center Undiksha. This research use desciptive qualitative approach. The sampling technique used in this research was purposive sampling with interview techniques in collecting research data. The population in this research are taxpayers who carry out the duty to annual tax return through e-Filing. Meanwhile, the sample in this research were taxpayers whose reporting the annual tax return were assisted by Tax Volunteers in the 4 (four) placements. The results of this research indicate that taxpayer assistance activities by tax volunteers in helping to fill individual annual tax returns are very effective. This can be seen from the satisfaction of taxpayers after receiving assistance by Tax Volunteers. Taxpayers are satisfied with the assistance of tax volunteers because the annual tax return reporting process is easier, faster and Tax Volunteers are able to guide Taxpayers in filling out their own. This assistance helps reduce the difficulties experienced by Taxpayers in understanding SPT filling independently. Taxpayer satisfaction is expected to increase compliance in reporting the Annual Tax Return. The sustainability of the Tax Volunteer program is also highly expected because it is considered very effective for taxpayers who do not understand the procedures for submitting annual tax return, especially those who are not yet competent with technological advances.</em></p><p><strong><em>Keywords</em></strong><em>: Perception, Assistance, e-Filing, Tax Volunteers</em></p><p> </p><p><strong>ABSTRAK:</strong> Penelitian ini bertujuan untuk menggali persepsi wajib pajak atas kepuasan pendampingan yang dilakukan oleh Relawan Pajak di lokasi penempatan relawan pajak.

Penelitian Lingkungan dan Kebencanaan Geologi Kelautan Perairan Teluk Jakarta (Tanjung Kait – Muara Gembong) dilakukan pada bulan Oktober - November 2010. Uji logam berat (Cu, Pb, Zn, Cd, dan Cr) dilakukan terhadap 28 contoh air laut dan 28 contoh sedimen dasar laut menggunakan metoda Atomic Absorption Spectrophotometry (AAS). Tujuan penelitian ini adalah untuk mendapatkan data dan informasi kondisi lingkungan terkini dari kandungan logam berat dalam air laut dan sedimen dasar laut. Kandungan logam berat (air laut dalam mg/l : sedimen dasar laut dalam ppm) terukur sebagai berikut : Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Berdasarkan Metode Storet dapat dilihat nilai status mutu air laut perairan ini adalah -12, berarti bahwa kualitas air laut di perairan termasuk kelas C (tercemar sedang). Sedangkan status mutu sedimen di perairan menunjukkan skor nilai status mutu sedimen adalah 0, yang berarti bahwa kualitas sedimen termasuk kelas A (tidak tercemar/memenuhi baku mutu). Jelas terlihat bahwa nilai ambang batas (NAB) logam berat dalam sedimen jauh lebih tinggi dari NAB logam berat dalam air. Kata kunci: logam berat, sedimen dasar laut, air laut, nilai status mutu Marine Environmental and Geological Hazard Survey In Jakarta Bay Waters (Tanjung Kait - Muara Gembong) conducted in October-November 2010. Testing of heavy metals (Cu, Pb, Zn, Cd, and Cr) performed on 28 samples of sea water and 28 subsurface sediment samples using the method of Atomic Absorption Spectrophotometry (AAS). The purpose of this study was to obtain data and information on current environmental conditions of heavy metal content in seawater and subsurface sediment. Heavy metal content (sea water in mg/l: subsurface sediment in ppm) measured as follows: Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Based on the Storet method shows the value of water quality status of sea waters is -12, which means that the seawater quality in these waters belong to a class C (medium contaminated). While the status of sediment quality in these waters indicate subsurface sediment quality score status value is 0, which means that subsurface sediment quality belongs to the class A (not polluted/correspond to the quality standards). It is clearly seen that the threshold value (NAV) of heavy metals in sediments is much higher than the NAV of heavy metals in water. Keywords: heavy metal, subsurface sediment, seawater, quality score status
