Abstract

Fast, reliable, and accurate topography measurement is needed for a study and evaluation of P3SON Hambalang area. Experimental Station for Sabo, therefore, was given a mandate to perform the topography measurement. Measurement has been carried out using fotogrammetry technique of remote sensing photos captured by drone. The results of drone measurement are Digital Surface Model (DSM), Digital Terain Model (DTM), and the final result is a contour map, which have high resolution data of 5 cm. The whole processes starting from field measurement until final results are obtained require around 4 to 5 working days, without any significant obstacles during both measurement and analysis. Due to the high-resolution result, fast, and cheap, it is foreseen that fotogrammetry technique using drone will be used more often in the future for topography measurement. However, drone topography measurements experience a difficulty in the non-vulkanic rivers (river with water table). The riverbed cannot be well measured by drone, especially for the rivers with high sediment concentration such in general rivers in Indonesia.

Abstract

Main issues frequently faced by communities living in the city of Jakarta is salt water intrusion. This paper analyzes the extent of the distribution of saltwater contamination to coastal aquifers in Jakarta, the method used is the open source program FREEWAT. modeling is carried out in five scenarios, namely (1) reduction of 50% of groundwater use, (2) reduction of 25% of groundwater use, (3) existing groundwater use in 2012, (4) increase of 25% of groundwater use, and (5) increase of 50% of groundwater use. From the modeling results, the distribution of saltwater contamination on each layer of the aquifer of Jakarta. In unconfined aquifer the existing condition is scenario 3 intrusion as far as 1.604 m, on scenario 1 there is an intrusion decrease of 38%, in scenario 2 there is an intrusion decrease of 13%, in scenario 4 there is an increase in intrusion by 17% and on scenario 5 increase intrusion by 25%. In upper confined aquifer, the existing condition, namely scenario 3, has occurred as much as 1.809 m intrusion, in scenario 1 there is an intrusion decrease of 23%, in scenario 2 there is an intrusion decrease of 8%, in scenario 4 there is an increase in intrusion by 19% and in scenario 5 increase intrusion by 26%. In middle confined aquifer, the existing condition is scenario 3, 1.927 m intrusion occurs, on the scenario 1 there is an intrusion decrease of 23%, in scenario 2 there is an intrusion decrease of 9%, in scenario 4 there is an increase in intrusion by 16% and in the scenario 5 increase intrusion by 22%.

Abstract

The Pusat Pendidikan Pelatihan dan Sekolah Olah Raga Nasional (P3SON) construction project was conducted at Hambalang, Sentul, Bogor, West Java. The project area covers 32 hektares. The P3SON project is located at a small mountain, called Gunung Hambalang, which has steep slope and thick clay layer. Generally, Hambalang morphology has a slope of about 1045, and at some places the buildings are built on steep slopes with the degree of steepness more than 45. Based on to the bore log, the rock profile is silt rock with the deepness of 0-6 m, and under 6 m, there is a hard clay layer. Clay layer if it is in contact with water will become impermeable and thus swell. During the high intensity rainfall event, the landslide risk is high. In order to strengthen the slope stability, an outer subsurface drainage at the East side and also horizontal subsurface drainage system in the area itself are proposed. The twin iron pipes are designed for the East side drainage system with the diameter of 20-35 cm and laid 5 m under the surface elevation. Technically, there are fifteen locations that need horizontal drainage installation. Horizontal drainage pipes are designed with 10 cm diameter and 8 m interval between pipes. The length of the horizontal drainage pipes is 15-20 m with slope of 10. Due to the fact that the silt layer depth is 0-6 m, then the horizontal drainage pipes will be located in 3-5 m depth from the surface. Optimistically, this system will reduce the landslide risk in Hambalang area.

Abstract

Transpirasi sebagai salah satu komponen dari evapo-transpirasi memberikan kontribusi aliran masa yang besar dari permukaan tanah. Banyak metode telah di aplikasikan untuk menghitung besarnya komponen-komponen evapotranspirasi ini. Sebagian besar kajian dilakukan pada skala lokal maupun regional dan hanya ada sedikit kajian yang menghitung besarnya transpirasi secara global. Transpirasi global yang dihitung baik dengan model maupun dengan teknik isotop menghasilkan nilai transpirasi yang rendah untuk model dan tinggi untuk teknik isotop dibandingkan dengan pengukuran. Hal ini mengindikasikan bahwa berapa nilai yang akurat dari transpirasi global masih merupakan tantangan. Oleh karena itu, kajian ini bertujuan untuk menghitung besarnya transpirasi global dan penguapan dari tanah dengan menggunakan teknik isotop yang datanya diambil dari hasil model GCM yang dilengkapi dengan modul isotop. Hasil perhitungan dengan teknik isotop nampak menjanjikan dengan nilai fraksi transpirasi sebesar 80% pada daerah yang ditumbuhi tanaman, and lebih rendah dari 50% pada daerah gurun. Fraksi transpirasi global dari hasil perhitungan adalah sebesar 69% dengan 43% air hujan yang jatuh menguap kembali ke atmosfer melalui transpirasi tanaman. Meskipun metode keseimbangan masa isotop dapat diaplikasikan ke TES satelit data, fraksi transpirasi yang dihasilkan masih menunjukkan adanya masalah pada resolusi data yang dihasilkan. Dengan adanya peningkatan resolusi satelit pada masa yang akan datang, perhitungan komponen-komponen evapo-transpirasi dengan menggunakan data isotop akan lebih akurat

Abstract

Pengelolaan daerah aliran sungai (DAS) bagian hulu merupakan kunci keberhasilan untuk mencapai ketersediaan air yang berkelanjutan. Selain itu kesalahan dalam mengelola lahan akan menyebabkan erosi yang dapat meningkatkan sedimentasi di badan air. Akibat erosi tanah sisa-sisa tanaman yang telah melapuk menjadi humus juga ikut tererosi. Hal ini akan mengakibatkan hilangnya karbon di lahan yang tererosi dan masuk ke perairan. Model Soil Water Assessment Tool dapat diaplikasikan untuk mengevaluasi kondisi sedimen dan karbon organik di daerah tangkapan air dengan menggunakan data historis aliran dan meteorologi. Tujuan dari kajian ini adalah untuk mengidentifikasi parameter-parameter model Soil Water Assessment Tool yang sesuai untuk menduga laju sedimen dan menganalisis fluktuasi sedimen di sungai Jenebrang bagian hulu serta mengkaji kandungan karbon organik dalam sedimen. Proses kalibrasi dilakukan dengan menyesuaikan 26 parameter dengan menggunakan Algoritma SUFI2. Dari hasil kalibrasi dapat diidentifikasi 19 parameter yang sensitif. Hasil simulasi sedimen pada bulan basah lebih tinggi dibandingkan pada bulan kering. Fluktuasi karbon organik sama dengan fluktuasi sedimen. Berdasarkan hubungan tersebut, karbon organik dalam jangka panjang dapat diduga dari hasil simulasi sedimen dengan menggunakan model Soil Water Assessment Tool.
