Abstract In Each activity in the oil and gas industry there are risks that could hamper the project and also there is a huge risk to the environment, social and economic. Besides oil and gas industry projects also have the potential to be dangerous to life, property and the environment, the hazard can occur if the activity is not controlled and regulated by appropriate. Basically, the disaster is certainly not possible to be planned and can occur at any time. But the circumstances of a disaster can be anticipated, that is the way to plan preventive measures and control.Based on the description above, this paper aims to discuss risk factors and risk assessment techniques that can help sustainable development programs. From the results of this study note that the risk factors of projects in the oil and gas industry is very complex, so a risk analysis must be done from various aspects, namely the project itself, the environment and disaster and should be integrated with aspects of sustainable development. As for the suggested technique is a combination of monte carlo and system dynamics. KeywordsSustainable Development, Risk Assessment Techniques, Combination Monte Carlo and System DynamicsAbstrak Dalam setiap kegiatan di industri minyak dan gas ada risiko yang dapat menghambat proyek dan juga ada risiko besar terhadap lingkungan, sosial dan ekonomi. Selain proyek industri migas juga berpotensi membahayakan kehidupan, properti dan lingkungan, bahaya bisa terjadi jika aktivitasnya tidak terkontrol dan diatur dengan tepat. Pada dasarnya, bencana ini tentu tidak mungkin direncanakan dan bisa terjadi kapan saja. Namun keadaan bencana dapat diantisipasi, itulah cara untuk merencanakan tindakan pencegahan dan pengendalian. Berdasarkan uraian di atas, makalah ini bertujuan untuk membahas faktor risiko dan teknik penilaian risiko yang dapat membantu program pembangunan berkelanjutan. Dari hasil penelitian ini diketahui bahwa faktor risiko proyek di industri minyak dan gas bumi sangat kompleks sehingga analisis risiko harus dilakukan dari berbagai aspek, yaitu proyek itu sendiri, lingkungan dan bencana dan harus diintegrasikan.

One of the important oil and gas industry is oil and gas pipeline which serves to support the gas transmission and distribution process. The oil and gas pipeline routes are so long and cross through some areas that certainly raises the risk of adversely affecting the environment, especially for the pipeline located in a densely populated area, where at certain conditions, the pipe can leak and may cause the explosion. Many researches have been conducted concerning on the project pipeline risks which concluded that the oil and gas pipeline project has very complex risks. In addition, the oil and gas project may cause a potential disaster. Currently oil and gas companies have been implementing risk management to minimize the negative impacts, but the negative impacts are still occurred. This is due to ineffective risk management implementation. This study aims to analyze the effectiveness of risk management system for oil and gas pipeline project in Java Island. Based on a deep study literature review, it shows that the effectiveness of risk management can be achieved by taking account into environmental, social and economic factors that are the pillars of sustainable development system. The potential disaster was also to be considered as an addition factor. Therefore, four identified factors were analyzed using Analytical Hierarchy Process (AHP) method. Data were obtained using questionnaire which were distributed to oil and gas project team. It is found that the most factors to be considered was social aspect (40%) and the other factors contributed 31% for disaster, 15% for economic, 14% for environment. Those factors should be taken account in the design stage as the most priority.

Kondisi tanah di Jalan poros Desa Trucuk Kecamatan Trucuk Kabupaten Bojonegoro saat ini mengalami kerusakan, menyebabkan pengendara merasa tidak nyaman. Keadaan semakin bertambah buruk saat musim hujan datang, banyak lubang tertutup oleh genagan air. Jalan poros di Desa Trucuk sebelumnya sudah di paving, akibat dari daya dukung tanah yang rendah, jalan mulai rusak bergelombang dan berlubang. Salah satu cara menangani permasalahan tanah yang terjadi di jalan poros Desa Trucuk dengan daya dukung rendah ialah dengan cara stabilisasi tanah. Tujuan penelitian ini adalah memanfaatkan bahan tambah Kapur, NaOh dan Sabut Kelapa sebagai bahan stabilisasi tanah ekspansif jalan poros desa Trucuk Kecamatan Trucuk Kabupaten Bojonegoro, menggunakan penelitian eksperimen di laboratorium Universitas Bojonegoro variasi persentase penambahan kapur 3% + NaOH 3% + sabut kelapa 2%, Hasil penelitian tanah yang diambil menunjukan jenis tanah ekspansif berdasarkan Klasifikasi AASHTO mempunyai Batas Cair (LL) sebesar 51,09%, Indek Plastisitas (PI) sebesar 16,45% dan PI < LL-30 tergolong tanah lempung golongan A-7-5, bisa dikatakan bahwa tanah ini merupakan agregat berbutir halus/lempung yang termasuk ke dalam kriteria yang buruk apabila digunakan sebagai material tanah dasar. Dengan penambahan Kapur, NaOh dan Sabut Kelapa indek plastisitas mengalami penurunan hingga 9,88 %. Nilai CBR mencapai kestabilan optimum pada campuran 3% Kapur + 3% NaOh dan 2% Sabut Kelapa dengan nilai CBR 55.77% dari nilai CBR tanah asli sebesar  47.34%, maka disimpulkan bahwa Kapur, NaOh dan Sabut Kelapa memiliki pengaruh cukup baik dalam meningkatkan daya dukung tanah lempung ekpansif.

Infrastructure development is one of the efforts to improve the welfare of the community, but in its implementation, road construction projects have risks that can have an impact on the project as well as on the external side of the project. This research is a case study on the road widening project of Bojonegoro – Surabaya KM 107. The purpose of this research is to analyze the risks in the project using fuzzy logic. Based on the results of the analysis, it can be concluded that the Bojonegoro - Surabaya highway widening project has 10 risk factors, namely noise, air pollution, heavy equipment vibration, traffic accidents, congestion, reduced parking space, increased fuel consumption of road users, decreased income of people in surrounding locations, conflict between road users, covid 19. The results of the analysis using a risk matrix, all risk factors are at a moderate level, but the results of the analysis using fuzzy, there are 2 risks that are at a high level, namely traffic congestion and a decrease in people's income in surrounding locations.
