Abstract

Landslide and erosion disasters are become increasingly common in the last decade which resulted in financial losses and even human casualties. Therefore, disaster mitigation efforts of landslide and erosion are very important to be done immediately. A breakthrough of comprehensive and practical solution is highly expected for mitigation. Vegetation can improve slope stability, provide positive aspects for the environment, and provide mechanical and hydrological effects on slopes that are prone to landslide and erosion. The use of vegetation to mitigate landslide and erosion disasters is very potential to be developed because besides being effective, it is also economical and environmentally friendly. The mechanical aspects of plant roots is able to strengthen the soil. Plant root characteristics such as root architecture, root anchor index (IJA), root grip index (ICA) are important variables to determine the types of plants that will be used in mitigating landslide and erosion.

Abstract

Non-structural elements of multi-story buildings need to be taken into account in the mitigation of earthquake in order to ensure the safety of the occupants. The purpose of this study is to obtain information related to the hazard management of multi-story buildings’ non-structural elements from the authorities, namely FEMA and SPRINT-Lab. This study is a qualitative study focused on reviewing the information that is relevant for future adaptation in Indonesia. The collected literature was then analyzed descriptively. The results of this review underlined the three most important stages that became the focus of hazard management from multi-story buildings’ non-structural elements, namely: the process of identification, the process of prioritization and the process of determining mitigation actions that need to be taken. Future research should be focused on developing a methodology that can be used to calculate the risk level of building occupants by considering the number of occupants and the level of danger of each object present with the occupant's mobility pattern in a certain area and time.

Abstract

Flood disaster that occur in the Kali Bekasi watershed often cause damage of property and casualties. The watershed is divided into two main parts namely upstream and downstream watersheds which are limited by Bekasi Dam. High rainfall in the upstream often causes flooding in Pondok Gede Permai Estate, Bekasi City. To improve community preparedness, a flood early warning system (FEWS) has been installed which consists of 5 monitoring stations along the Cileungsi and Cikeas Rivers in 2017. The main question that needs to be answered in this paper is how long the upstream flood peak will reach community settlements ? Based on the recorded data on the LEWS instrument, the flood peak travel time from the upstream station to the affected area can be calculated empirically. The results ofthe time calculation can be used by stakeholders to carry out evacuation after an early warning is given. The parameter used in this analysis are the river water level at several monitoring stations on the Cileungsi River, namely: Cibongas Irrigation Dam,WIKA Bridge and Pondok Gede Permai.Bencana banjir yang terjadi di DAS Bekasi sering menimbulkan kerugian harta benda maupun korban jiwa. DAS ini terbagi atas dua bagian utama yaitu DASbagian hulu dan bagian hilir yang dibatasi oleh Bendung Bekasi. Curah hujan yang tinggi di DAS bagian hulu sering menimbulkan banjir di Perumahan Pondok Gede Permai, Kota Bekasi. Untuk meningkatkan kesiapsiagaan masyarakat di perumahan tersebut, maka telah dipasang sistem peringatan dini banjir (Flood Early Warning System/LEWS) yang terdiri dari 5 stasiun pemantauan di sepanjang Sungai Cileungsi dan Cikeas pada tahun 2017. Pertanyaan utama yang perlu dijawab dalam makalah ini adalah berapa lama puncak banjir di bagianhulu akan mencapai permukiman masyarakat ? Berdasarkan basis data yang telah terekam pada instrument LEWS tersebut, waktu perjalanan puncak banjir dari stasiun hulu menunju area terdampak dapat dihitung secara empirik. Hasil perhitungan waktu tersebut dapat dimanfaatkan oleh para pemangku kepentingan untuk melakukan evakuasi setelah peringatan dini diberikan. Parameter yang digunakan dalam analisis ini adalah tinggi muka air yang di beberapa stasiun pemantauan di Sungai Cileungsi yaitu : Dam Irigasi Cibongas, Jembatan WIKA dan Pondok Gede Permai.

Abstract

The newest finding in 2016 about Baribis thrust, if it is pulled straight from Cibatu to Tangerang, it is roughly found that this fault passes through several sub-districts in Jakarta. Meanwhile, Center of Jakarta as the capital city, many governmental, economic, and business activities are conducted in this area. And also Geographic Information System (GIS) techniques are commonly used for monitoring and damage assessment for many natural and geological hazards. The present study, GIS techniques have been used to generate various thematic layers to assess earthquake hazard with a suitable numerical ranking scheme, mesh processing, and spatial data integration. The results also show that the proposed model provides reasonable earthquake potential index (EPI) from elevation, slope, magnitude, active fault, and epicentre parameters compared to the peak ground acceleration (PGA) in Center of Jakarta. The result of the EPI map explained just a little area in Center of Jakarta has very high EPI. Very high EPI area mostly in southeastern part in the study area, exactly in Menteng sub-district. And also illustrated, spatially in the more northward area indicate the smaller of the EPI in the study area. EPI resulted from the calculation of surface parameter have the same indication or same trend with PGA.

Abstract

Land use land cover change and forestry play an important role in the global environmental change. Anthropogenic activities in changing the land have caused earth surface change. This change has a role to increase the change of global greenhouse gases in the atmosphere which also causes the increase greenhouse gases emission. Land cover change and forestry are sectors which cause high carbon emission. Therefore, a study in land cover change and estimation of carbon emission becomes important. This study took place in Jambi Province where deforestation has been in a high pace. In 2009 and 2011, the dominant area is dryland agriculture mixed with bush followed by secondary forest, i.e. 25% and 18.6%, respectively (in 2009); and 37.1% and 18.9%, respectively (in 2011). For the secondary forest, the gain was caused by the conversion of dryland agriculture mixed with bush and shrub into secondary forest. The loss of secondary forest is the highest among other forest cover at around 87,765 Ha due to the conversion into bare land and dryland agriculture mixed with bush. Due to land cover change in Jambi Province, the estimation of nett emission in the period of 2009-2011 is 4.8 Mt CO2-eq/year.
