Abstract. The issue of mercury pollution in Aceh waters, Indonesiadue to gold mining activities hasbeen a polemic in local media and Aceh Local Government and the communities have much concern on this case. The impact of mercury pollution in the Teunom and Tangse (Aceh)rivers was often assumed that it has similarity with Minamatapollution in Japan. This article intends to enlighten the characteristic mercury either as elements or compounds including methyl mercury which is highly toxic. Gold mining using elemental mercury is poorly soluble in water, the solubility is only 0.06 g per ton of mercury but the solubility can increase indark the sea-bed and ina lot of dissolved oxygen. Based on the properties of solubility, it is understood that the mercury levels in the Teunom and Tangse rivers still below the tolerance limit, but the gold mining activities still bringsthe risk of environmental damage especially inadequate supervision. Many researchers were trying to prove the natural conversionfrom mercury into methyl mercury (biomethylation) but they usedthe salt instead of the elemental mercury in their experiments. Methyl mercury is found in nature, but the process mercury conversion into methyl mercury compound is still controversial and it has not obtained adequate evidence for the natural alteration,therefore gold pollution which is due to releasing elemental mercury into environment might not be analogue to Minamata case.Keywords: Aceh; Methyl-mercury; Minamata; Mining; Gold Abstrak. Informasi pencemaran merkuri di perairan Aceh dan kaitannya dengan aktivitas pertambangan emas telah menjadi polemik sehingga menjadi perhatian Pemda Aceh dan Masyarakat. Dampak pencemaran merkuri di Sungai Teunom dan Tangse sering dianalogikan dengan kasus pencemaran merkuri di teluk Minamata, Jepang. Artikel ini bermaksud memberi pencerahan kharakteristik merkuri baik sebagai unsur maupun sebagai senyawa seperti metil merkuri yang sangat beracun. Penambangan emas menggunakan unsur merkuri yang sukar larut dalam air, kelarutannya hanya 0,06 g per ton unsur merkuri  namun kelarutannya dapat meningkat jika di dasar laut yang gelap dan banyak oksigen terlarut. Berdasarkan sifat kelarutannya, dapat dipahami bahwa kadar merkuri di Sungai Teunom masih di bawah batas toleransi, namun aktivitas penambangan emas tetap saja memiliki resiko kerusakan lingkungan apalagi jika tidak mendapat pengawasan yang memadai. Banyak peneliti berusaha membuktikan perubahan merkuri menjadi metil merkuri (biometilasi) tetapi mereka menggunakan garam merkuri dan bukan unsur merkuri dalam ekperimen mereka. Metil merkuri memang ditemukan di alam tetapi proses perubahan dari senyawa merkuri menjadi metil merkuri masih diperdebatkan dan belum diperoleh bukti yang kuat perubahan dari unsur merkuri menjadi metil merkuri dalam air sehingga di Peraian Aceh belum tentu tercemar metil merkuri sebagaimana kasus Minamata.Kata kunci: Aceh; metil-merkuri; minamata; penambangan; emas

Abstract

Mangrove, Rhizophora mucronata, grows in the intertidal area, which contains much organic matter and varying salinity. The organic matter content is influenced by the bacterial community that inhabits the ecosystem, but information regarding the bacterial community, especially in the mangrove root system, is not widely available. There are several challenges in completing this information, one of which is that the method used is still in a conventional form. Developments in environmental DNA analysis can support and complement this information. However, this method must be optimized because the organic matter content and salt variations affect the extraction results. Thus, this study aimed to determine the optimal approach for extracting bacterial DNA from mangrove sediments. The analysis used two methodologies: manual DNA extraction techniques based on buffer modification and DNA extraction kits. There were four different treatments, namely the soil DNA isolation plus kit (M1), the fecal / soil microbial quick-DNA miniprep kit (M2), glass powder with charcoal (M3), and glass powder with skimmed milk (M4). DNA samples were obtained from each method and assessed for concentration and purity using a nanodrop. In addition, the resulting DNA's quality was analyzed using 1.5% agarose. The results obtained were in the M2 treatment, which showed optimal results compared to the others. M2 uses a bead-based beating and spin column method to achieve optimal DNA concentration through high molecular weight. The DNA obtained was also protein-free, and several samples were contaminated with humic acid, namely KL.S1, KL.S4, and T7.S4.Keywords:Bacteria 16SBead beatingDNA ExtractionSedimentSpin column

Abstract

Contamination and pollution of heavy metals in the bottom sediment can pose serious issues to marine organisms and human health. Jakarta Bay which is located adjacent to the capital city of Indonesia is notorious for its pollution problems. The purpose of this research was to assest the contamination levels of heavy metals Hg, Pb, and Cd in sea-bottom sediments based on an index analysis approach (contamination factors, geo accumulation index, pollution load index). Sediment samples were collected from 31 stations in Jakarta Bay. Heavy metal concentration was measured using Atomic Absorption Spectrophotometer (AAS). The results showed that an average mercury (Hg) concentration ranged from 0.150 to 0.530 µg.g-1 with an total average of 0.362 µg.g-1, Lead (Pb) from 14.870 to 35.650 µg.g-1 with an total average of 21.774 µg.g-1, Cadmium (Cd) 0.110-0.280 µg.g-1 with an total average of 0.190 µg.g-1.The average concentration of Hg, Pb, and Cd is still lower than the sediment quality threshold values set by the Office of the State Minister of Environment of Indonesia  2010. The results of the index analysis showed that the average value of contamination factor (CF) are Hg 0.685, Pb 0.558, and Cd 0.380 respectively (low contamination) and geo accumulation index values are Hg 0.237, Pb -1.655, and Cd 0.069 respectively (unpolluted to moderate polluted). Overall, based on the pollution load index value is -0,511 (PLI 1), sediments in these waters are categorized as not yet polluted by Hg, Pb and Cd. This situation  is so necessary to be maintained, that in order for the preservation of marine resources will remain.Keywords: Jakarta Bay, sediment, pollution, heavy metals, assessmentABSTRAKKontaminasi dan pencemaran logam berat pada sedimen dasar dapat menimbulkan masalah yang serius bagi biota laut dan kesehatan manusia.

Abstract

The objective of the study was to analyze the policy of increasing the effectiveness of providing PUMP funds to fishermen groups in Kota Banda Aceh. Mina Rural Business Development Program (PUMP) was one of the models developed by the Ministry of Marine Affairs and Fisheries to overcome poverty for coastal communities. From the previous research data, it was known that PUMP funding is considered ineffective because there were still many people who did not benefit from this PUMP fund and the improper use of PUMP funds targeted by beneficiary communities. To improve the effectiveness of PUMP funding, it was necessary to do in the policy analysis on the effectiveness of this PUMP fund. Analysis Hierarchy process (AHP) was used to look at the policies to be used for the effectiveness of PUMP grants. The method of collecting data was the interview or deep interview with policymakers in DKP Aceh Province, with NGOs and academics in Banda Aceh. The Results of Analysis Hierarchy process shows the criteria that mainly influence the increasing effectiveness of PUMP funding assistance to the fishermen economy are human resources, followed by time and human resources. While the policy priority of increasing the effectiveness of PUMP funding to the fishermen economy is to increase the capacity of the fishermen's supervisor, followed by management financial training of fishermen and intensively monitoring post-aid activities.Penelitian ini bertujuan untuk menganalisis kebijakan peningkatan efektivitas pemberian bantuan dana PUMP pada kelompok nelayan di Kota Banda Aceh.
