Abstract

The volcanic eruption of Mount Sinabung has caused the loss of human lives. Hence, for minimizing losses, disaster mitigation is needed. The purpose of this study is to determine the policy directives in mitigating volcanic eruptions of Mount Sinabung. The method to determine the volcano hazard area is the assessment method using geographic information system techniques. Indicators in determining the hazard level are slope, soil type, geology, landform, vegetation, and land use. As for determining the policy directive, this study used the AHP method. The results show that 45 percent of the area is a high risk of the volcano hazard area. From the research, the appropriate policy directive for mitigation is relocating the area further from the volcano.

Abstract

Pariaman city is one of the areas most severely affected by natural disasters that have the potential for tsunamis. The impact of the earthquake potential tsunami seen in fatalities and damage to infrastructure, both residents' homes and other public facilities. The impact also caused the community to lose their livelihood. Most of the people of Nagari Gunung Padang have livelihoods as farmers, after the earthquake disaster has the potential of a tsunami, many people lost their land and gardens because of the cliff ruins and buried by landslides that caused the land cannot be recycled. By taking into account all the physical, social, and economic aspects, this is the reason for the researchers' interest to conduct research related to the direction of Natural Disaster Mitigation Policy based on Environmental Physical Conditions and Socio-Economic Characteristics of Coastal Area Communities in Pariaman city. With Mixed Method methods, such as simultaneous and sequential data collection. Then descriptive physical environmental conditions and socio-economic characteristics, and Focus Group Discussion (FGD) in policy direction. The results of this study in the form of an explanation of the physical, social and economic Pariaman city, as well as the policies needed in disaster mitigation in Pariaman city

Abstract

The purpose of this study is 1) to know the condition of physical parameters, free groundwater chemistry; 2) to what extent of leachate water contamination of against free groundwater in the Air Dingin landfill, Padang City. The data analysis technique used in this study is based on Minister of Health Regulation Number 419/1990 concerning Water Quality Requirements and Supervision, and Government Regulation Number 82/2010 concerning Management of Water Quality and Water Pollution Control. The water quality physics test results show 1) smell and taste meet the quality standard requirements; 2) water temperature meets quality standard requirements; 3) watercolour meets quality standard requirements; 4) Dissolved Solids (TDS) meet the quality standard requirements; and 5) Suspended Solids (TSS) meet the quality standard requirements, while the chemical quality of water shows 1) pH below the quality standard; 2) Arsenic below the quality standard; 3) Cadmium is below the quality standard; 4) Chromium below the quality standard; 5) Iron below the quality standard; 6) Lead below the quality standard; 7) Manganese below the quality standard; 8) Free groundwater below the quality standard; and 9) COD below the quality standard.. Leachate water that comes out laterally from the garbage pile tends to flow following the contour of the land towards a lower direction.

Abstract

The utility of synthetic cleaners or commonly called as detergents have developed far indeed in this century. The effective and efficient use of detergents in cleaning process, was attracted to be used in laundry?s industry commercially, though, it has some drawback to the society and environments. Since the active materials in the compounds can cause irritating to the skins, cataracts to mature eyes and some other environmental issues due to the excess of foams can prevent oxygen dilution in the water so it be hazardous to water living organisms. Once the promising method to solve this problem is by photo-degradation using photo-catalyst. Photo-catalyst is the process using light and catalyst in order to accelerate chemical transformation, thus,  solar or uv-rays can be used as light sources. This research aims at to show the ability of catalyst TiO2 to degrade active material in linear alkyl benzene sulphonate (LAS) and alkyl benzene sulphonate (ABS) which is available in commercial detergent. Photo-degradation of LAS and ABS compounds was determined by optimum capacity TiO2 and irradiance time. Whereas, for environmental application, the degrade compounds such Rinso® and Wipol® was chosen since it is commonly used in daily life. Beside, artificial water waste and laundry water was chosen to show the environmental effect.  The result shows that the optimum number of catalyst TiO2 addition for LAS degradation was 1.5 g, and optimum time was 120 minute. Whereas  the optimum number of catalyst TiO2 addition for ABS degradation was 2.0 g, and optimum time was 120 minute as well. Thus, for detergent Rinso®, at optimum catalyst addition, we found degradation number was 75.83%, and for detergent Wipol®, at optimum catalyst addition, we found degradation number was 57.94%. Whereas,  for artificial waste at optimum catalyst addition, we found degradation number was 91.32%, and for laundry water waste at optimum catalyst addition, we found degradation number was 70.27%.Key words : Photodegradation, surfactant, TiO2, photocatalyst

Abstract

The decreasing of environmental quality in padang is caused by the changes of the land, the increasing number of vehicles and the increasing number of population. The solution to overcome these problems is by providing a green open space at universitas negeri padang (unp). The objectives of this study are 1) to analyze the needs of green open space at unp, 2) to plan the construction of open green space at unp. The method employed in this study was survey by using spatial analysis remote sensing data from google earth. The results of the study revealed that unp had open green space as large as 7.643 ha. The area of green open space at unp that fulfilled the width criteria was as much as 10%, and the fulfillment of population and clean air criteria was as much as 20%. However, the minimum width criterion of green open space, which was as much as 30%, was not fulfilled yet. The discrepancy between the area of open green space and the criteria of minimum width (30%) was 0.447 ha. Such lack of green open space can be filled by: optimizing  the unoccupied land as large as 1.4 ha by planting the clump, providing 2308 flower’s pots, and making use of building shelter and building lobbies, and campus corridor to be planted with clump, ornamental plants or other types of epiphytes and lianas.
