Abstract

The research was one part of oil spill contingency plan (OSCP) developed for Delta Mahakam area, where oil & gas exploration and exploitation linked with rich biodiversity supporting coastal community livelihood. Environmental sensitivity  analysis for OSCP only do two early stages of OSCP scope, which integrated with the dangers of coastal vulnerability. This analysis mapped environmental component from oil pollution become sensitivity rangking as an effort to support response development strategies and priorities for the coastal resources protection. The aims of this research were (1) to establish environment sensitivity rank and (2) to identify primary factor supporting the environmental sensitivity for OSCP in south Delta Mahakam area. The result of analysis showed environmenal sensitivity was 62.37% (517.52 km), its mean very high sensitivity. Then the high sensitivity criteria was 11.31% (94 km). The criteria of medium sensitivity was 11.92% (99 km). While for low sensitivity and very low sensitivity respectively were 1.78% (15 km) and 12.64% (105 km). Based on Principal Component Analysis (PCA), 36.01%  variability was explained by axis of factor 1. The others variability 18.53% and 13.93% were explained by axis of the factor 2 and factor 3. Axis of factor 1 for coastal exposure (EK), oil residence index (OR), coastal type (TP), and biological resources (SH) had a quite large linear combinations coefficient, amounted to 0.94 (EK&OR), 0.83 (TP) and 0.75 (SH). This indicated a very high contribution for environmental sensitivity OSCP level drafting. On axis of factor 2, the linear coeffisien combinations for the resource utilization of port (PL) was 0.83 and settlement (PM) was 0.85. Axis of factor 3 contributed 0.75 and 0.66 on migas platform (PO) and placement of passive fishing gear/catchment area (AT). However, the utilization of coastal resources for PL, PM, PO and AT were on axis of factor 2 and factor 3 had a considerable distance with its SI variable. This possible caused by each variable percentage distribution which the value was very minor ranged 0.001-0.52%, so its not representated coastal resources elements closeness with SI variable in the study area.Keywords: Environmental Sensitivity, Oil Spill Contingency Plan, Mahakam Delta

Abstract

In general, natural resources capable of generating foreign exchange, such as: gas, petroleum and various other minerals are found in locations that have high productivity. Conditions of waters that have high productivity serves to support the sustainability of biological resources (e.g.: fish, mangroves, seagrass beds, seaweed and coral reefs). The government in this case the Ministry of Environment and Forestry (formerly the Ministry of the Environment) actually has made the signs of a rule that must be met by business actors who conduct activities in sensitive areas to environmental changes. PT. Total E & P Indonesia (TEPI) located in Balikpapan has long been engaged in exploration and exploitation of oil and gas in the Mahakam Delta. The large flow of branches of the Mahakam River empties into the Mahakam Delta provides a promising business opportunity for the farmers to open their business. While TEPI has oil wells are scattered in the delta area, pipelines are needed to collect the oil from the wells to the processing site. Because of the large number of streams causing many oil and gas pipes to cross the river (river cross pipes) that require special handling and meet the standards of technical rules and environment set by the government to be safe from passing boats or fishing boats that pass at the location. This study was conducted to predict the extent of exposed areas of exposure, especially the TSS concentration generated from the dredging activities in the pipeline. The simulation results show that the area of impact (TSS> 80 mg / L) is 74275.13 m2 dominantly moving westward from the dredging location (RC-06 = River Crossing Pipe No. 6). The farthest distance of the affected river body (TSS> 80 mg / L) to the west is 557.00 m from RC-06. The farthest distance of the affected river body (TSS> 80 mg / L) to the northeast is 240.81 m from RC-06. The farthest distance of the affected river body (TSS> 80 mg / L) to the southeast is 216.98 m from the RC-06 location. There is no water mass with TSS> 80 mg / L entering the pond. Sedimentation due to dredging activities is not accumulated and has no impact on shrimp farming business. The results of this study is expected to make a scientific basis in helping solve the problem of compensation requested by the farmers to TEPI due to decreased tambak production.

Abstract

Ngurah Rai Forest Park, is one of the remaining mangrove ecosystems located in the Benoa Bali Bay, Indonesia. Ecosystem in this forest park is threathened due to the construction of Bali Mandara Highway. This  study was conducted to determine the impact of the construction of the Bali Mandara Highway to the mangrove ecosystem in Ngurah Rai Forest Park. In this study, qualitative method was applied in order to compare the environmental parameter of mangrove ecosystem before and after construction of the highway. The construction of the Bali Mandara Highway affects several physical parameters of the mangrove ecosystem. The salinity, pH value and DO content are physical parameters which decreasing after the contruction. The decreasing also identified for current velocity,  during the high tide  current velocity decline to 0 - 0.44 m/s while during the low tide it goes down to 0 - 0.84 m/s. On the other hand, sedimentation area increases by 485.62 ha which causes silting. The vegetation analysis shows that Bali Mandara Highway has no significant impact to the diversity of mangrove species in Ngurah Rai Forest Park. Sonneratia alba still dominate the mangrove vegetation in those area.

Abstract

Penelitian ini bertujuan untuk menentukan status keberlanjutan pada dimensi ekonomi dan memberikan rekomendasi kebijakan pengelolaan budidaya di Teluk Saleh Kabupaten Sumbawa. Analisis keberlanjutan budidaya laut untuk komoditi rumput laut dan ikan kerapu sistem KJA dilakukan dengan metode Rap-Insus-Seaweed (Rapid Appraisal –Indeks Sustainability of Seaweed) dan Rap-Insus-Grouper (Rapid Appraisal –Indeks Sustainability of Grouper) telah dimodifikasi dari program RAPFISH. Hasil penelitian menunjukkan bahwa nilai indeks tingkat keberlanjutan pada dimensi ekonomi budidaya rumput laut sebesar “39,74” dan untuk budidaya ikan kerapu sistem KJA sebesar “31,23”. Nilai tersebut terletak antara 25,00 - 49,9 berarti “Kurang Berkelanjutan”. Nilai indeks dan status keberlanjutan saat ini menunjukkan kondisi ekonomi wilayah perairan tersebut kurang mendukung pengelolaan budidaya laut, sehingga diperlukan intervensi kebijakan melalui pemberian bantuan mudal usaha, pelatihan teknis budidaya dan pengolahan, dan peningkatan kapasitas kelembagaan pemasaran untuk meningkatkan status keberlanjutan pengelolaan dimensi ekonomi.Title: Sustainability Analysis of Mariculture Management in Saleh Bay of Sumbawa DistrictThis study aimed at determiny value of the index and the sustainability status in terms of economic dimension and provide recommendations for policies on marine aquaculture management in the Saleh Bay. Rap-Insus-Seaweed (Rapid Appraisal of Sustainability-Index Seaweed) and Rap-Insus-Grouper (Rapid Appraisal of Sustainability-Index Grouper) modified from Rapfish program were use in this study. Results showed that the index level of sustainability in terms of economic dimension were “39.74” and “31.23” for seaweed grouper  espectively. This value laid between 25.00 and 49.9 indicating that both management status were “Less Sustainable”. These values indicate that the economic conditions of that particular site was not support sustainable management of the marine aquaculture. Hence, government policing intervention through increased capital, technical training in aquaculture and processing as well as improvement in market institution are required.

Abstract

Tide is one of the important factors that affect the oceanographic processes around widely as waters flow. Tides also give significant effects against the dynamic of coastal area. This research was conducted considering the importance roles of tides data against all oceanographic phenomenon that gives the effects on activities around the area of coastal waters. This research was conducted around the area of east coast of Bintan Island Riau Archipelago Province in December 2017. Tidal data is retrieved from the global tidal modelling uses MIKE 21. The results of the analysis show the range of tidal height on the east coast of Bintan Island during 2007-2017 is 0.70-3.50 m of height range with the average of mean sea level (MSL) is 2.20-2.60 m. Generally, tidal fluctuations on east coast of Bintan Island form an asymmetric pattern which is a common pattern occurring in any waters. The tidal type of the east coast of Bintan Island is mixed predominantly semi diurnal with the value of formzahl number in each station respectively is 1.19-1.44. The interesting phenomenon obtained from this research is during 2007-2017 the maximum of sea level height in each station tends to decrease, this is considered attractive because over the past 20 years earth surface temperature have tended to increase so that melting of ice in polar has implications for increasing of sea water volume. Keywords: Tide, harmonics component, oceanography, east coast of Bintan Island
