Untuk mengurangi pengeluaran impor BBM serta meningkatkan produksi minyak nasional, pemerintah melakukan pembukaan wilayah kerja dan eksplorasi migas secara masif. Semakin tinggi dan maraknya aktivitas pada industri migas, akan memiliki dampak negatif di lingkungan, termasuk didalamnya polusi tumpahan minyak di tanah. Polusi ini dapat mempengaruhi kualitas lingkungan serta penurunan tingkat kesehatan, ekonomi, dan sosial masyarakat yang terdampak. Beberapa metode telah dilakukan dalam hal penanggulangan tumpahan minyak  dan metode yang paling ramah lingkungan adalah bioremediasi. Tujuan penelitian ini adalah untuk Menganalisis efektivitas bioremediasi untuk mendegradasi tumpahan minyak di tanah, menganalisis jenis bioremediasi yang paling efektif serta mengevaluasi kendala dalam mengimplementasi bioremediasi di lapangan. Penelitian ini menggunakan metode sequential explanatory dengan menggabungkan data yang didapatkan dari hasil uji coba laboratorium dan wawancara. Berdasarkan penelitian, bioremediasi berhasil dalam menurunkan kandungan hidrokarbon dalam tanah dengan tingkat efektivitas penurunan lebih dari 70%. Efektivitas tertinggi didapat pada bioremediasi jenis fitoremediasi yang merupakan kombinasi antara Tanaman Vetiver, bakteri K4, dan Mikoriza. Secara skala laboratorium, bioremediasi dinilai efektif untuk mendegradasi kandungan hidrokarbon, tetapi secara praktikal di lapangan, bioremediasi dinilai tidak efektif karena memiliki kekurangan pada waktu pengerjaan dan langkah pengerjaan dinilai tidak praktis. Menurut Expert judgement, Sikap pemerintah pada kasus bioremediasi yang menimpa PT. Chevron membuat pengembangan dan implementasi bioremediasi di Indonesia terhambat karena pihak perusahaan minyak dan gas enggan untuk menggunakan metode bioremediasi untuk menghindar atau mengantisipasi masalah seperti yang dialami PT. Chevron. Diharapkan pemerintah mengkaji ulang peraturan-peraturan mengenai penanggulangan oil spills dan lebih aktif dalam memotivasi pihak-pihak terkait terutama oil company dan kontraktor untuk melakukan penelitian dan pengembangan untuk bioremediasi.
To reduce spending on fuel imports and increase national oil production, the government is opening massive oil and gas exploration and work areas. The higher and increasing activity in the oil and gas industry, will have a negative impact on the environment, including pollution of oil spills on the ground. This pollution can affect environmental quality and decrease the health, economic and social level of the affected people. Several methods have been carried out in handling oil spills and the most environmentally friendly method is bioremediation. The purpose of this study is to analyze the effectiveness of bioremediation to degrade oil spills on land, analyze the most effective types of bioremediation and evaluate the obstacles in implementing bioremediation in the field. This study uses a sequential explanatory method by combining data obtained from the results of laboratory trials and interviews. Based on research, bioremediation was successful in reducing the hydrocarbon content in the soil with a reduction in effectiveness of more than 70%. The highest effectiveness was obtained in the type of phytoremediation bioremediation which is a combination of Vetiver, K4, and Mycorrhizae. On a laboratory scale, bioremediation is considered effective to degrade hydrocarbon content, but practically in the field, bioremediation is considered ineffective because it has shortages at the time of processing and the work steps are considered impractical. According to the Expert judgment, the government's attitude in the bioremediation case that befell PT. Chevron made the development and implementation of bioremediation in Indonesia hampered because the oil and gas companies were reluctant to use the bioremediation method to avoid or anticipate problems such as those experienced by PT. Chevron. It is expected that the government will review the regulations concerning the prevention of oil spills and be more active in motivating the relevant parties, especially oil companies and contractors to conduct research and development for bioremediation.

Di Indonesia, sudah terjadi 14 kasus skala besar tumpahan minyak yang disebabkan oleh tabrakan kapal. Salah satu tindakan penanggulangan secara mekanik adalah dengan menggunakan oil skimmer tipe piringan. Efektivitas kinerja oil skimmer pada pengangkutan tumpahan minyak dipengaruhi oleh berbagai faktor seperti kedalaman celup piringan atau luas daerah yang tercelup, luas daerah penyapuan wiper, tingkat ketebalan minyak pada permukaan piringan, dan tingkat putaran piringan. Sampel minyak yang digunakan adalah oli mesin diesel fastron SAE 15W-40 dan sampel air yang digunakan adalah air laut. Penelitian dilakukan dengan variasi kedalaman celup piringan 27 mm dan 55 mm atau setara dengan luas daerah tercelup 31,35 cm2 dan 88,83 cm2. Waktu pengujian dilakukan selama 5 menit dengan pengambilan data sebanyak 3 kali untuk satu rentang putaran. Berdasarkan hasil perhitungan secara teoritis semakin meningkatnya putaran pada piringan, hasil pengangkutan tumpahan juga akan semakin tinggi. Hal ini dibuktikan dengan melakukan pengambilan data dengan melakukan pengujian. Pengambilan tumpahan minyak akan lebih efektif dengan menggunakan putaran piringan rendah, dikarenakan hasil tumpahan minyak yang terangkut lebih didominasi oleh minyak dibandingkan dengan air. Pada pengujian ini, semakin tinggi putaran pada piringan menghasil jumlah air terangkut semakin banyak.
In Indonesia, there have been 14 accidents of oil spill as the result of ship collisions. There have been several methods in handling oil spill accident, one of the most effective methods is using mechanical oil skimmer with disc plate. The effectiveness of the oil skimmer 39 s performance on handling oil spills is influenced by various factors, such as the depth of the disk submerged or the disk surface area dipped into the oil spill, the area of the wiper sweep, the thickness of the oil on the disk surface, and the rotation speed of the disk. The oil samples used are diesel engine oil with 15W 40 SAE and the water sample used is sea water. The experiment was conducted with variation of 27 mm and 55 mm of disc submersion depth or equal to dipped surface area of 31.35 cm2 and 88,832 cm2. The duration of the test for 3 data is 5 minutes. Based on theoretical calculations, the increase of rotation speed of the disk, the result of spill transport will also be higher. This is proved by the experimental results. The lifting process of oil spill is more effective with low rotation speed, because the result of oil spill transported will be more dominated by oil than water. In this test, the higher the rotation speed of the disk, the higher the water produced.

ABSTRACT
Oil spills are ecological disasters that have a major impact on the environment and can be categorized as serious environmental disasters. The focus of this paper is to discuss the risks and readiness of the oil spill response occurring in the Madura Strait. This paper offers an outline of holistic theory, not only about environmental aspects, but social aspects of society (fishermen). The objective is to analyze the potential risks of oil spills in the oil and gas industry, analyze the preparedness and awareness of nearby communities in handling oil spill contamination. The research method in this paper is quantitative and qualitative which refers to statistical analysis. This paper examines the public perception in handling oil spill contamination based on interviews with 100 fishermen informants. This study will determine the worst rating of oil spills that occur based on environmental sensitivity index based on holistic, environmental, social and economic aspects. Community cognition will affect people's readiness to deal with oil spills, and readiness can reduce the risk of oil spills. This finding is a notion of influence but insignificant, the most influential aspect is preparedness. These findings contribute to SDG targets number 11 and 14 which are cities and communities that are sustainable and life under water. This study is important because the oil spill poses significant risks to biodiversity both at sea and in the community.
