Climate change impacts related flood hazard to communities around Bantimurung Bulusaraung National Park, Indonesia

Abstract: Climate variability in a region leads to the increased rainfall intensity during the rainy season and the increasing number of days of the dry season. This condition is happening in most of Indonesia, especially in the South Sulawesi province where it has a quite complex characteristic of the ecosystem. One of them is Bantimurung-Bulusaraung National Park with a special characteristic of the landscape in the form of karst area and the people in the buffer villages located in Maros, Pangkajene Kepulauan and Bone Regions depend on their livelihoods in the park. One of the impacts of climate changes happening around the National Park area is the increasing potential of the flood. The flood mostly occurs due to the high rainfall in the rainy season supported by the characteristics of the land in the form of karst area that very quickly passes the water. Flood hazard analysis in Bantimurung-Bulusaraung National Park area was assessed by using Soil and Water Assessment Tools (SWAT) model on actual condition (climate period 2004-2013) and projection of climate change in the 2030s using scenario RCP 4.5 (rainfall scenario tend to decrease) and RCP 6.0 (rainfall scenario tend to increase). Based on the SWAT model analysis results, it is known that there are areas of the buffer villages of Bantimurung-Bulusaraung National Park, which has a very high level of flood, which the actual condition of the affected area is 10,380.31 ha and on climate change projection of scenario RCP 4.5 covering 9,061.99 ha and RCP 6.0 scenario covering 24,188.26 ha.

Utilizing Mid-long Term Maintenance Management Policy for Sustainable Maintenance of Infrastructure Facilities

Abstract: Infrastructure has a significant function in supporting citizen's life and serving economic activities. Look carefully on that situation; maintenance, repair and rehabilitation have been surely advanced up to now. In this context, it is substantial to perform an approach that decreases life-cycle cost by reasonably allocating of limited resource and by implementing an efficient management of infrastructure maintenance, repair and rehabilitation. This paper proposes a methodology of maintenance management with strategy and policy approach. The maintenance management policy is developed from viewpoint of mid-long term maintenance plan. This policy is working with building facilities maintenance. This study has made a contribution to the field of building maintenance by utilizing maintenance management policy. The maintenance policy approach can be extended to apply to various infrastructures as well.

Plastic Particles in Silverside (Stolephorusheterolobus) Collected at Paotere Fish Market, Makassar

Abstract: Plastics represent the latest contaminant in the marine environment. Although plastics without doubt represent a uniquely valuable material particularly in construction, packaging and fishing gear applications. Current research on plastic debris in digestive tract content of pelagic fish is part of ongoing collaboration between University of Hasanuddin and University of California at Davis. Locally caught and consumed Silverside (Stolephorusheterolobus) or widely known as anchovies has been the subject on this studies. Freshly landed fish were collected from Paotere fish market, which is also the biggest fish wholesale location at Makassar City, South Sulawesi, Indonesia. At laboratory fish digestive tracts were removed and digested in 10% KOH at 60o C overnight, followed with plastic particles observation using binocular microscope. Four out of 10 fish investigated were found to contained plastic particles in their digestive tract. This is the first work on plastic debris in fish gut ever conducted in the region, which is in accordance to previous works on plastics debris elsewhere and will be further discussed for their possible effects, both on food safety and human toxicology.

Investigation of LMP forecasting for congested power systems

Abstract: Transmission congestion occurs when power flow over a transmission line exceeds its thermal limit causes high fluctuation of locational marginal prices (LMPs). It eventually influences the revenue, incomes, and profits of the market participants. Hence an accurate LMP forecasting is important to ensure economical operation as well as proper scheduling of generation resources. It helps market participants in making effective decisions and providing better risk management. This paper analyses the impact of congestion in LMP volatility then proposes a new advanced method for LMP forecasting based on adaptive neuro-fuzzy inference system (ANFIS).
