Effectiveness of Infrastructure Flood Control Due to Development Upstream Land Use: Case Study of Ciliwung Watershed Siti Murniningsih, Evi Anggraheni World Academy of Science, Engineering and Technology International Journal of Environmental and Ecological Engineering Vol:10, No:2, 2016 Effectiveness of Infrastructure Flood Control Due to Development Upstream Land Use: Case Study of Ciliwung Watershed Siti Murniningsih, Evi Anggraheni This causes flood in the residential areas. For example, some Abstract—Various infrastructures such as dams, flood control households in Kampung Melayu, East Jakarta, are located on dams and reservoirs have been developed in the 19th century until the the banks of the river, so during the rainy season, these areas 20th century. These infrastructures are very effective in controlling the are flooded as a result of living in the river banks. This also river flows and in preventing inundation in the urban area prone to happens in other residential areas along Ciliwung River to the flooding. Flooding in the urban area often brings large impact, affecting every aspect of life and also environment. Ciliwung is one of border of Jakarta - Bogor. the rivers allegedly contributes to the flooding problems in Jakarta; Various efforts have been made by the government in various engineering work has been done in Ciliwung river to help responding to the floods, both structural and non-structural. controlling the flooding. One of the engineering work is to build Ciawi Structural flood control system in Ciliwung includes the Dam and Sukamahi Dam. In this research, author is doing the flood manufacture of a number of water gates or flood observation calculation with Nakayasu Method, while the previous flooding in that post, flood prevention to a certain height with dikes, and also case study is computed using Level Pool Routine. The effectiveness of these dams can be identified by using flood simulation of existing lowering the water level by normalization, diversion, canal, and condition and compare it to the flood simulation after the dam interconnection of the rivers. The core concept of the flood construction. The final goal of this study is to determine the channel is controlling the flow of water from upstream and effectiveness of flood mitigation infrastructure located at upstream regulating the volume of water coming into Jakarta. In addition, area in reducing the volume of flooding in Jakarta. the government also seeks to reduce the flood discharge at the dam as well as attempting to reduce the pool of the polder Keywords—Effectiveness, flood simulation, infrastructure pumping and drainage system. The main problem in the control flooding, level pool routine. rainfall runoff in urban areas generally consists of the need to control the depth of peak discharge and flow throughout the I. INTRODUCTION system, in order to avoid unwanted puddles. Fig. 1 is an AND arrangement in upstream areas has influence on the overview map of the 13 rivers that pass Jakarta and water Lrunoff in the downstream area. If the downstream area of a management system in Jakarta. watershed is urban area, it can be ascertained that the flooding Damping peak discharge using the reservoirs is a common will be a threat to the urban areas. It is like in the capital Jakarta alternative. This reservoir has the added advantage of allowing in which Ciliwung river coming from the highlands, located in the ongoing infiltration and evaporation so that in addition to the border district of Bogor and Cianjur Regency (Gunung dampen peak flows, they also reduce runoff volume. Reservoirs Gede, Gunung Pangrango and Puncak area), which is the such as dams can also be a sediments reservoir in addition of longest river in the Greater Jakarta area with a length of nearly being water quality control.

  • (Pb) Pollution in the River Estuaries of Jakarta Bay
    The Sustainable City IX, Vol. 2 1555 Analysis of lead (Pb) pollution in the river estuaries of Jakarta Bay M. Rumanta Universitas Terbuka, Indonesia Abstract The purpose of this study is to obtain information about the level of Pb in the sediment of the estuaries surrounding Jakarta Bay and to compare them. Samples were taken from 9 estuaries by using a grab sampler at three different location points – the left, right and the middle sides of the river. Then, samples were collected in one bottle sample and received drops of concentrated HNO3. The taking of samples was repeated three times. In addition, an in situ measurement of pH and temperature of samples was taken as proponent data. The Pb concentration of the river sediment was measured using an AAS flame in the laboratory of Balai Penelitian Tanah Bogor. Data was analyzed statistically (one way ANOVA and t-test student) by using SPSS-11.5 software. The results show that Pb concentration in the sediment of the estuaries surrounding Jakarta was quite high (20–336 µg/g). The sediment of Ciliwung River in the rainy season was the highest (336 µg/g). Pb concentration of sediment in the dry season was higher than that in the rainy season, except in Ciliwung River. It was concluded that all rivers flowing into Jakarta Bay make a significant contribution to the Pb pollution in Jakarta Bay, and the one with the largest contribution was Ciliwung River. Keywords: Pb, sediment, estuaries, dry season, rainy season, AAS flame. 1 Introduction Jakarta Bay (89 km of length) is formed as a result of the extension of Karawang Cape in the eastern region and Kait Cape in the western region into the Java Sea (Rositasari [1]).

Ismi, 2Irawan Sugoro 1 Department of Biology, Faculty of Science and Technology University Al Azhar Indonesia, Jakarta, Indonesia; 2 The Center of Isotope and Radiation Application (PAIR), The National Agency of Nuclear Energy (BATAN), Jakarta, Indonesia. Corresponding author: D. Elfidasari, [email protected] Abstract. Ciliwung River is one of the most polluted freshwaters in Indonesia, shown by its color, smell, and the wastes. Generally, the presence of heavy metals is an indicator of pollution in any river. Furthermore, the survival of waters biota is determined by the pollution levels of the water and sediment, including the Pterygoplichthys pardalis fish dominating the river. The purpose of this study therefore was to record the concentration of heavy metals in water, sediment, and P. pardalis in the Ciliwung River from upstream in Bogor to its downstream in Jakarta. The X-Ray Fluorescence (XRF) spectrometer was used to analyze the metals. The results showed that the concentrations of heavy metals such as Cd, Hg, and Pb were relatively high in the water and sediment of the river, exceeding the threshold of Indonesian Government Regulation. The highest concentration of these metals was found in the samples from Ciliwung River Jakarta area. The concentrations of these metals were quite high in the P. pardalis flesh exceeding the threshold set through the provisions of National Agency of Drug and Food Control (BPOM) and Indonesia National Standard (SNI). On analysis, there was a strong correlation between the metal content of fish flesh and sediment.

With its dynamic characteristics, a river must be periodically examined to determine its water quality. This study aims to investigate the carrying capacity of the Brantas river in East Java, Indonesia. The observation was done by measuring TSS (Total suspended solid), TDS (Total dissolved solid), and oil and grease in the upstream zone of the Brantas river. This research used a descriptive method. The determination of the research stations was based on the condition of the watershed and its surroundings, assuming that there was a decrease in water quality. The sampling points include Pendem Bridge (1), DAM (local water company) Sengkaling (2), Simpang Remujung Bridge (3), and Samaan District (4). The results demonstrated that the upstream Brantas river at each sampling point had different pollution levels. Generally, the sampling point 1 (Pendem Bridge) was the cleanest zone compared to other sampling points. On the other hand, sampling point 4 (Samaan District) was the most polluted site of the upstream zone.

    PROC. ITB Eng. Science Vol. 36 B, No. 2, 2004, 109-123 109 Studying Landslide Displacements in Megamendung (Indonesia) Using GPS Survey Method Hasanuddin Z. Abidin 1, H. Andreas 1, M. Gamal 1, Surono 2 & M. Hendrasto 2 1 Department of Geodetic Engineering, Institute of Technology Bandung, Jl. Ganesa 10, Bandung, Indonesia, e-mail: [email protected] 2 Directorate of Volcanology and Geological Hazard Mitigation, Jl. Diponegoro 57, Bandung 40132 Abstract. Landslide is one of prominent geohazards that frequently affects Indonesia, especially in the rainy season. It destroys not only environment and property, but usually also causes deaths. Landslide monitoring is therefore very crucial and should be continuously done. One of the methods that can have a contribution in studying landslide phenomena is repeated GPS survey method. This paper presents and discusses the operational performances, constraints and results of GPS surveys conducted in a well known landslide prone area in West Java (Indonesia), namely Megamendung, the hilly region close to Bogor. Three GPS surveys involving 8 GPS points have been conducted, namely on April 2002, May 2003 and May 2004, respectively. The estimated landslide displacements in the area are relatively quite large in the level of a few dm to a few m. Displacements up to about 2-3 m were detected in the April 2002 to May 2003 period, and up to about 3-4 dm in the May 2003 to May 2004 period. In both periods, landslides in general show the northwest direction of displacements. Displacements vary both spatially and temporally. This study also suggested that in order to conclude the existence of real and significant displacements of GPS points, the GPS estimated displacements should be subjected to three types of testing namely: the congruency test on spatial displacements, testing on the agreement between the horizontal distance changes with the predicted direction of landslide displacement, and testing on the consistency of displacement directions on two consecutive periods.

Rawamangun Muka, RT.11/RW.14, Rawamangun, Kec. Pulo Gadung, Kota Jakarta Timur, DKI Jakarta 13220 [email protected] Abstract-Jakarta is one of the cities that is often hit by Dutch government built 3 dams. Jago Dam and Udik floods. The problem of flooding in Jakarta is actually not a Dam, both of which are located at the top of the river and new thing. Many factors make Jakarta city vulnerable to Bendungan Hilir which are located downstream of the flooding. These factors are natural and anthropogenic Ciliwung river (Jakarta) [10]. As a result of a massive factors. These natural factors are: (1) Jakarta is located in flood in 1876, the Dutch government rebuilt the Flood the lowlands near the coast, (2) there are 13 rivers flowing Canal which stretched from the Manggarai area in the through Jakarta, and (3) the high annual rainfall in the center of the city to the Muara Angke area in the coastal Ciliwung watershed (> 3000 mm). While anthropogenic factors are: (1) landscape changes due to high competition area of Jakarta. The existence of this canal is intended to in land-based economic activities, (2) poor urban and rural prevent flooding in Jakarta. It is hoped that through this spatial planning, and (3) lack of integrated institutional canal, flood water will flow faster to the Java Sea on the capacity and arrangements, especially in cross-border coast of Jakarta.

To allow direct comparisons for four rivers, unit free This paper presents a comparative study on short- formulas from RMSE and MAE are also employed. term water level prediction using fuzzy adaptive These are known as root mean square percentage systems (FAS) and artificial neural networks error (RMSPE) and mean absolute percentage error (ANNs). The short-term water prediction (three (MAPE). days or less prediction) is crucial for flood warning system. This prediction is usually ANNs and FAS produced similar pattern results. calculated using conceptual or physical-based However, ANNs gave slightly better results for models. almost all rivers. Out of four rivers, only the Bengawan Solo performed very well up to three Although conceptual or physical-based models days ahead predictions (RMSPE < 25%). The can lead to better understanding of hydraulic and model of the Ciliwung River could perform hydrological processes, these types of models are relatively well. For ANN models, both the often constrained by data availability, funding Bogowonto and Telomoyo River could actually limitation and human resources. In this paper, the gave reasonable results with RMSPE < 25% for one ANNs and FAS methods are applied to handle day ahead. Their performance decreased such situations where data are limited, such as in significantly for a longer period.
