Vulnerability is a loss rate perceived from elements at risk owing to the impact of hazards on determined magnitude and frequency. Vulnerability assessment of elements at risk is a critical component in the risk assessment framework. Considerable studies regarding flash floods have been conducted, but the depth of information on vulnerability is still limited. This study presents a model of the physical vulnerability of buildings caused by the incidence of flash floods, which is strengthened through intensity of the impact process and loss. This model used a non-linear regression approach using behavioural data in the form of the propagation height of the flood. The order-2 polynomial distribution can represent the relationship between the magnitudes of the best process and loss rate. The results are the risk assessments of an exposed area in mitigation strategies.

Pembangunan yang baik akan terselenggara apabila diawali dengan perencanaan yang baik pula, sehingga mampu dilaksanakan oleh seluruh pelaku pembangunan serta memenuhi kebutuhan masyarakat. Pembangunan yang mendekati kebutuhan masyarakat merupakan sebuah tuntutan yang tidak dapat ditunda lagi di Era Otonomi Daerah. Namun demikian, dalam pelaksanaannya seringkali dijumpai banyak kendala dalam setiap tahapannya, dan salah satu diantaranya adalah perencanaan. Secara ideal pembangunan daerah haruslah melibatkan partisipasi masyarakat dan berdasarkan kebutuhan riil masyarakat. Namun keinginan ini seringkali tidak tercapai karena berbagai hal dan keterbatasannya. Agar tujuan pembangunan dapat terwujud maka peran serta dan kerjasama dari seluruh masyarakat yang ada sangat diperlukan sekali, karena salah satu faktor yang menentukan dalam terlaksananya suatu pembangunan adalah faktor manusia itu sendiri. Dalam pelaksanaan pembangunan, partisipasi masyarakat sangat diharapkan dalam setiap tahapan pembangunan yang dimulai dari tahap perencanaan, tahap pelaksanaan, tahap pemanfaatan, pelestarian dan tahap evaluasi.

The provision of clean water in Takengon City, Aceh Tengah Regency is provided by PDAM Tirta Tawar, one of which is through the water network of Oregon Mendale Water Treatment Plant (IPA). However, a preliminary survey at the Oregon Mendale IPA source suggested inadequate water for the community. The aim of this research is to know the factors that must be fulfilled so that a clean water network system can run smoothly. This includes water flow, pressure and flows continuity, maximum daily factor (Fmax) and real peak factor (Fpeak) of the existing network. This study is also to understand the clean water distribution network in the Oregon Mendale IPA resource area. This research uses a descriptive method and field observation. This study suggests the following: the average water consumption is 0,426 m3/customer/day, the maximum water pressure is 1.517 m and the continuity of flow is 6 hours every day. The maximum daily factor value (Fmax) in Kecamatan Kebayakan is 1.13-1.39 and the peak hour factor (Fpeak) is 1.13-1.41. These results suggested that the existing Oregon Mendale IPA is not running optimally.

Sedimentation is commonly found as one of the problems affecting the function of reservoirs in Indonesia. High risk soil erosion leads to the increase in sediment production which negatively influencing the capacity or functional age of the reservoir. Generally, several reservoirs in Indonesia are experiencing the operational problem due to the increasing of sedimentation throughout the year. The data presented in this article was obtained from the measurement of sediment in the area of Keuliling reservoir, including: The data of suspended sediment at every Keulling reservoir water inlet, the data of bedload sediment at the bottom of the Keuliling reservoir, the hydrometric data, including the water velocity and channel profile, where the sampling of bedload and suspended sediment sampling was conducted at each inlet. the data sediment volume at the dam reservoir. The data of suspended and bedload sediment were obtained by taking the samples and analyzed in a laboratory. The measurement was conducted three times in five months. The data of water velocity was also generated based on the measurement using a currentmeter. Meanwhile, the sediment volume data in the water storage of reservoir was gathered by conducting a bathymetry and topographic survey at the dam reservoir location and then comparing it with the pre-existing bathymetry and topographic data.

The Pandrah Irrigation Area is a technical irrigation network whose water source comes from the Krueng Pandrah river. Pandrah Weir was built in 1987 located in Samagadeng Village, Pandrah District, Bireuen Regency. It has an area of 1,203 hectares of irrigated rice fields. In its development, the damage that occurs in the Pandrah irrigation area also cannot be ignored. It is necessary to review it by assessing the performance of the irrigation system. The purpose of this study was to determine the performance index of the Pandrah irrigation system using the MASSCOTE (Mapping System and Service for Canal Operation Technique) method approach. The assessment of the performance index of the Pandrah irrigation system using the MASSCOTE method approach is carried out by evaluating the Rapid Appraisal Procedure (RAP) on four main indicators, namely service indicators, indicators for Farmers Using Water (P3A), indicators for the operator's Human Resources (HR). In the evaluation of the RAP, it is the value of observations of the respondents of OP officers and P3A farmers who are presented in a questionnaire to cross-assess each respondent in irrigation management. The results of the research on the performance appraisal of the Pandrah irrigation system based on the MASSCOTE method with RAP evaluation showed that the performance index of the absolute value (Level of Service) was 3.05. Hence, the performance index of the Pandrah irrigation system in the existing conditions was in the Good classification. This index and classification value shows the value of irrigation operations in fulfilling services from irrigation management carried out by operators / OP officers and felt by irrigation service beneficiaries, namely P3A farmers.
