ABSTRAK : Industri besar yang berada di Cilacap salah satunya adalah industri minyak dan gas (MIGAS) PT. Pertamina Refinery Unit IV Cilacap, dimana lokasi ini berada di sekitar perairan Sungai Donan yang menjadi objek penilitian. Aktivitas industri yang berada di dekat perairan dapat menyebabkan perairan mengalami pencemaran. Senyawa hidrokarbon adalah salah satu bahan yang dapat menyebabkan pencemaran pada suatu perairan, senyawa ini merupakan senyawa dominan penyususun minyak bumi. Tujuan penelitian ini adalah mengetahui hubungan kandungan total hidrokarbon pada air dan sedimen di perairan Sungai Donan, Cilacap. Penelitian ini dilaksanakan di perairan Sungai Donan Kabupaten Cilacap pada bulan Februari 2019 - April 2019. Lokasi penelitian dibagi menjadi tiga stasiun yaitu Stasiun A (dekat hulu), B (muara Kali Anget), C (muara Sungai Donan). Sample yang diambil yaitu Air permukaan dan sedimen setiap stasiun dengan tiga kali pengulangan setiap stasiun. Kandungan total hidrokarbon pada air di Sungai Donan yang tertinggi berada di Stasiun C sebesar 2.07 mg/L, kemudian di stasiun A sebesar 0.63 mg/L dan kandungan yang terendah pada Stasiun B sebesar 0.22 mg/L. Kandungan total hidrokarbon pada sedimen berbanding lurus dengan air, kandungan yang tertinggi terdapat pada stasiun C sebesar 574.39 mg/kg, kemudian di stasiun A sebesar 497.11 mg/kg, dan kandungan yang terendah di Stasiun B sebesar 261.40 mg/kg. Kandungan total hidrokarbon pada air di semua stasiun masih di bawah batas ambang baku mutu, sedangkan kandungan pada sedimen di semua stasiun sudah melewati baku mutu yang sudah ditetapkan.ABSTRACT: One of the large oil and gas industry in Cilacap is PT. Pertamina Refinery Unit IV Cilacap, where the location is located around the waters of the Donan River which becomes the object of the research. Industrial activities near the water can cause pollution. Hydrocarbon compounds are one of the ingredients that can cause pollution to water. This compound is the dominant compound of petroleum. The purpose of this research is to know the total content of hydrocarbons in water and sediment in the waters of Donan River, Cilacap. This study was held in the Donan River waters of Cilacap Regency in February 2019-April 2019. The location used in this research is divided into three stations: A station (near the upstream), B (Kali Anget estuary), C (Donan River estuary). The Sample is the surface water and sediment in each station that is repeated three times. The total content of hydrocarbons in water of the highest Donan river was at C station 2.07 mg/L, then at station A of 0.63 mg/L and the lowest content at station B amounted to 0.22 mg/L. Total hydrocarbon content in sediment is directly proportional to water. the highest content found at the C station amounted to 574.39 mg/kg, then at station A of 497.11 mg/kg, and the lowest content at station B amounted to 261.40 mg/kg. The total content of hydrocarbons in water at all stations is still below the threshold of quality standards, while the content on the sediment at all stations has passed the quality standards that is already set.

Hydrocarbons contamination of the marine environment generated by the offshore oil and gas industry is generated from a number of sources including oil contaminated drill cuttings and produced waters. The removal of hydrocarbons from both these sources is one of the most significant challenges facing this sector as it moves towards zero emissions. The application of a number of techniques which have been used to successfully destroy hydrocarbons in produced water and waste water effluents has previously been reported. This paper reports the application of semiconductor photocatalysis as a final polishing step for the removal of hydrocarbons from two waste effluent sources. Two reactor concepts were considered: a simple flat plate immobilised film unit, and a new rotating drum photocatalytic reactor. Both units proved to be effective in removing residual hydrocarbons from the effluent with the drum reactor reducing the hydrocarbon content by 90% under 10 minutes.

Federal tax revenues from the main sectors of the Russian economy after the 1998 crisis are examined in the article. Authors present the structure of revenues from these sectors by main taxes for 1999-2003 and prospects for 2004. Emphasis is given to an increasing dependence of budget on revenues from oil and gas industries. The share of proceeds from these sectors has reached 1/3 of total federal revenues. To explain this fact world oil prices dynamics and changes in tax legislation in Russia are considered. Empirical results show strong dependence of budget revenues on oil prices. The analysis of changes in tax legislation in oil and gas industry shows that the government has managed to redistribute resource rent in favor of the state.

The article deals with the issues of political and economic power as well as their constellation on the market. The theory of public choice and the theory of public contract are confronted with an approach centered on the power triad. If structured in the power triad, interactions among states representatives, businesses with structural advantages and businesses without structural advantages allow capturing administrative rents. The political power of the ruling elites coexists with economic power of certain members of the business community. The situation in the oil and gas industry, the retail trade and the road construction and operation industry in Russia illustrates key moments in the proposed analysis.

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest
