Abstract

Jakarta has very complex problems from flood to traffic jams. One solution that has been considered is the utilization of underground space called as Infrastruktur Terpadu Bawah Tanah abbreviated as ITBT (Jakarta Integrated Tunnel) which is used for flood control and toll road. ITBT proposed as flood control consists of two traces, namely ITBT-1 from Balekambang to Manggarai and ITBT-2 from Ulujami to Tanah Abang. The performance effectiveness of ITBT-1 and ITBT-2 as flood controls assessed based on mathematical model approach that simulates the characteristics of floods in Jakarta. is the performance is done by predicting how much ITBT can reduce flood inundation (flood risk). The results indicate insignificant reductions since floodwaters diversion carried out by both ITBT only reduce the puddle within the controlled area, and create another in other areas. Flood inundation reduction is still more effective if done by river improvement. ITBT-1 would be more effective if the trace is transferred into east flood canal (BKT) or sea through alignment under BKT, moreover if there is an inlet regulation to ITBT-1.

Abstract

In this research calculates the efficiency of wave energy reduction by using permeable breakwater as an alternative coastal protection. The method used is to do physical modeling in the laboratory to get optimal efficiency. The preparation of the model scenario is done by changing the schematization of the model scenario by changing the permeable brackwater characteristics (width b and height h) to the water level d. and the T wave period. Wave energy is calculated at the location in front of the structure and behind the structure. After calculating the comparison of wave energy in the two locations, it can be obtained the efficiency value of wave energy reduction due to the existence of the structure. The influence of the structure dimension on the reduction of the highest wave energy is obtained with the highest energy reduction value when the condition h / B = 1 where the condition of the structure is the same as the width of the structure. In the conditions of damping the wave energy when compared to the water depth (d) the greatest energy reduction value is at d = 10 cm so that in its utilization as a wave energy damper the height of the structure must be higher than the mean Mean level level (MSL) in the area to be applied structure permeable breakwater will be placed.

Abstract

Monitoring kekeringan merupakan salah satu bentuk penerapan penanganan kekeringan berbasis manajemen risiko. Sebagai langkah awal, maka diperlukan monitoring data hidrologi, salah satunya adalahdata curah hujan (mm). Untuk keperluan monitoring kekeringan diperlukan beberapa pos hujan dari 147 pos hujan yang ada di Wilayah Sungai Pemali Comal, untuk mewakili wilayah/zonanya. Sehingga, penelitian ini difokuskan untuk memilih pos hujan berdasarkan pendekatan statistic dan survey kondisi fisik pos hujan. Pemilihan pos hujan dilakukan dengan menggunakan sistem clustering hujan bulanan dari BMKG, yangdisebut Zona Prakiraan Iklim (ZPI). Dalam analisis pemilihan pos hujan tahapan yang dilakukan adalah mengubah seri data hujan menjadi indeks kekeringan (Standardized Precipitation Index atau SPI12)skala waktu 12 bulan, memilih pos hujan yang mewakili kondisi kekeringan di setiap ZPI, dengan pendekatan statistik yaitu menggunakan Principal Component Analysis (PCA) dan berdasarkan survey lapangan. Darianalisa PCA dapat ditentukan pospos hujan terpilih berdasarkan perhitungan. Dari setiap ZPI dihasilkan 23 pos hujan utama dan beberapa pos cadangan. Pospos terpilih tersebut dilakukan cek/survey lapanganuntuk memeriksa kembali kondisi fisik pos hujan di lapangan ditinjau dari alat/tabung pengukur hujan, lingkungan, dan keamanan. Hasil analisis PCA dan survey lapangan diperoleh 15 pos hujan yang dinyatakan mampu mewakili tingkat kekeringan di wilayahnya.

Abstract

Salah satu alat yang digunakan dalam pengukuran debit di suatu saluran air atau sungai adalah dengan menggunakan Current Meter. Berdasarkan hasil pengukuran tersebut, debit aliran air dihitung menggunakan metode yang sudah ada. Mengingat muka air sungai dapat berubah sangat cepat terutama saat banjir, maka kepraktisan dan kecepatan pengukuran, serta penghitungan debit sangat diperlukan. Untuk menjawab tantangan tersebut diperlukan alat ukur Current Meter yang lebih praktis dan cepat dalam pengukuran dan perhitungan. Penelitian ini bertujuan untuk mengembangkan prototipe Counter Current Meter berbasis mikrokontroller yang dapat menyimpan data kecepatan air, menghitung data debit secara semi otomatis, dan dapat mengunduh data yang disimpan ke komputer. Hasil dari penelitian menunjukkan bahwa fungsi penghitung debit otomatis pada Counter hasil pengembangan dan perangkat lunak Counter pada komputer telah bekerja sesuai dengan perancangan. Perbedaan hasil perhitungan debit yang sangat kecil diantara perhitungan manual dengan perhitungan otomatis diduga disebabkan oleh perbedaan proses pembulatan yang mempengaruhi akurasi pada perhitungan.

Abstract

The implementation of a detailed test model for the design of the Semarang sea wall was carried out to determine the level of stability of the sea dike structure in the form of cube-shaped concrete block armor with 1 m side. Besides, a test model was also conducted to evaluate the elevation of the sea dike against various wave conditions and increase in water level due to land subsidence. The Semarang sea wall was designed to with stand waves and tides, as well as toll roads, so that the model test was carried out to test the stability of the protective and runoff layers. There are 5 test scenarios carried out, namely LS01, LS05, LS10, LS15 and LS15-120% where each scenario shows land subsidence that occurs after 1 year, 5 years, 10 years and 15 years assuming the amount of land subsidence in Semarang 0 , 1 m / year. The test model results show that the stability of the protective armor structure with the concrete cube is quite high, as evidenced by the damage level which is quite low (NoD <0.5) in all conditions of the test scenario. Runoff starts in the LS 10, LS 15 and LS 15 scenarios 120% for 1,192 lt / dt / m, 6,588 lt / dt / m and 20,215 lt / dt / m, respectively. The runoff that occurs can be categorized functionally unsafe for vehicles in status (unsafe at any speed) while for the condition of the structure it is categorized as no damage. Therefore, a comprehensive evaluation of the stability and elevation / peak elevation needs of the embankment needs to be carried out after a 10-year service period.

Abstract

The growth population every year in Bogor caused changes in land use and increased water demand in the Cisadane river basin. The purpose of this study is to analyze the water demand DMI, water availability, water balance and and to evaluate the scope of services on the present and future. Therefore, it is necessary to manage the allocation of water demand by using software DSS (Decision Support System), RIBASIM (River Basin Simulation). The data used in this study are : rainfall, irrigation, population and schematization (Schema of water allocation). This study used base time fram from 2015 - 2030 which refers to the 6 Cis project. The results of the analysis of the model, indicating that the water demand is dominated by DMI (Domestic, Municipal and Industry). In general, the existing surface water sources in most Cisadane river basin can meet various needs, but, because of the priority water demand is for the people, the scope of services (coverage) is a major concern; in this case, lack of water services to the District and City of Bogor was found, as indicated in graphic water demand of DMI (domestic, municipal, industrial) with SIPA (license of water extraction) in 2015 and 2030. Based on the obtained information that is required for optimalised scope of services water supply for the district and the city of Bogor in 2030.

Abstract

Waduk merupakan infrastruktur sumber daya air yang berfungsi multiguna. Namun demikian, waduk-waduk yang telah dibangun di Indonesia telah mengalami permasalahan eutrofikasi dan telah menjadi perhatian serius secara global. Karena itu, diperlukan upaya pengendalian yang tepat dengan mengetahui proses dan parameter kunci yang menyebabkan timbulnya eutrofikasi. Model matematis merupakan salahsatu alat yang dapat digunakan untuk menyimulasikan fenomena dan pengendalian eutrofikasi. Untuk mengkaji secara teoritis model-model eutrofikasi secara lebih rinci, termasuk yang telah diaplikasikan di Indonesia, maka kajian dilakukan menggunakan metode deskriptif. Kajian model mencakup relasi antarparameter kualitas air dan dinamika proses eutrofikasi. Model yang dikaji menggunakan asumsi tercampur sempurna dan multidimensi.Dengan demikian, output dari kajian ini adalah perbandingan dan perkembangan model eutrofikasi, usulan modelkonseptual serta piranti lunak yang dapat diterapkan untuk pengelolaan waduk tercemar di daerah tropis, khususnya di Indonesia. Hasil kajian menunjukkan bahwa model konsep yang diterapkan pada waduk-waduk tercemar di Indonesia sebaiknya merupakan gabungan dari konsep model ekologi, perhitungan berdasarkan volume kendali, memerhatikan kemampuan pengukuran variabel kualitas air pemicu eutrofikasi dan pengaruh sedimen dasar waduk.

Abstract

Changes in land use may affect the hydrology of a watershed. This study aims to assess the hydrological conditions due to land use changes. The hydrological condition was predicted under four scenarios: (1) scenario 1, land use condition as in map 2009; (2) Scenario 2 is a change of 50% cocoa-coffee agroforestry to clove system in upstream area, and to monoculture rubber system in the middle and downstream area; (3) Scenario 3 is a change of 25% cocoa-coffee agroforestry to clove system in upstream area, and to monoculture rubber system in the middle and downstream area; (4) Scenario 4 is a change of 50% cocoa-coffee agroforestry to clove system in upstream area, and to monoculture rubber system in the middle and downstream area with a reduction of deforestation rate by 50%); and (5), Scenario 5 is a change of 25% cocoa-coffee agroforestry to clove system in upstream area, and to monoculture rubber system in the middle and downstream area with a reduction of deforestation rate by 50%. The prediction of water balance was measuredusing GenRiver model. Result shows that land use changes under scenario 1 and 2 do not affect the hydrological conditions, but need to watch out for the occurrence of flash floods. Reduction of deforestation rate in scenarios 3 and 4 can further improve the watershed hydrological conditions and maintain peak discharge during the rainy season
