Abstract

Landslide occurred on June, 19th 2016 in Caok Village, Purworejo,Central Java. Caok Village is part of Menoreh hills area. Most of Slope in the landslide location has more than 20o. Before the landslide, rain occurred with maximum intensity 325mm/day. This is an indication that landslide was triggered by groundwater infiltration process, caused by high rainfall intensity and steep slopes. In this research, slope stability analyzed using Plaxis and Geo-slope software. Data that are soil engineering properties, steep slope, and groundwater table modelling with Plaxis and Geo-slope software to obtain slope stability and deformation. Minimum number factor of safety is 1,25 (Bowless 1984), without earthquake. Safety factor 1,162 obtained from Geo-Slope model, while with Plaxis resulted 0,9522 with maximum displacement 205m. Both the results of safety factor indicate that the location of the study are prone to landslide.

Abstract

A simulation using the HEC-HMS model has been carried out to discover height of flood level in mainpond. The result shows that existing condition of the pond is not sufficient for controlling flood although thepond had been dredged. Flood will overflow about 0.57-0.69m above the dyke in existing condition, andabout 0.062-0.12m in dredged condition. Suggestions for prevention action are adding the amount of intakepipes, increasing dyke elevation and extending the dredging area. Flood will also occur in pond 5particularly for the return period of 10 years if BPLS does not take serious action of prevention such asdredging and increasing dyke elevation.

Abstract

One of the solutions for water shortage in Grobogan District is groundwater utilization. Excessive groundwater pumping will decrease groundwater level and trigger a landsubsidence. It is necessary to conduct hydrogeological study to determine the groundwater storage in this area. The purpose of this research were to determine the hydrogeological conditions, aquifer characteristics and potential of groundwater storage in Grobogan district. This research used geoelectrical method to identify rock characteristics. The results showed that the geological formation in Grobogan district consisted of Qa, Tmpk, Tmpl, Tps, Tmw and Qp. Grobogan district had 5 aquifers system, there are: poorly productive aquifers, moderately productive aquifers, locally productive aquifers, extensive productive aquifers and region without exploitable groundwater. The aquifer layer consisted of sand, marl sandy, silty sand and calcareous sand. The unconfined aquifer was located at 1,2 - 58 m from soil surface with average thickness of 13,54 m and the hydraulic conductivity of 3,54 m/day. The confined aquifer depth can be estimated between 29 - 174 m from soil surface with average thickness of 37,4 m and the hydraulic conductivity of 3,87 m/day.The predicted groundwater storage in Grobogan district of unconfined aquifer was 401,33 l/sec and confined aquifer was 1.804,95 l/sec.

Abstract

Indonesia seringkali mengalami bencana alam, pada tahun 2008 Indonesia termasuk dalam 10 besar negara di dunia yang selalu mengalami bencana. Bencana terbesar yang terjadi adalah bencana hidrologi yang berhubungan dengan banjir, yaitu sekitar 34 %. Ini mengindikasikan bahwa kejadian banjir perlu ditangani secara saksama oleh berbagai pihak. Pendekatan yang digunakan adalah secara nonstruktur dengan mengembangkan sistem peringatan dini banjir, menggunakan pendekatan pemodelan hidrologi dan hidraulik untuk menentukan karakteristik aliran banjir. Input yang dipakai dalam model menggunakan beberapa sumber data, seperti data pengamatan lapangan dengan sistem pengiriman data secara telemetri, data radar, satelit, dan data prakiraan hujan dari berbagai Numerical Weather Prediction (NWP), serta prakiraan muka air laut dengan menggunakan Astronomical Tide dan South China Sea Model. Penggunaan beberapa sumber data dimaksudkan untuk memperpanjang lead time yang dihasilkan oleh model. Sistem peringatan dini banjir Jakarta (J-FEWS) telah dioperasikan secara perdana untuk kejadian banjir pada akhir tahun 2012 dan awal tahun 2013. Hasil yang diperoleh menunjukkan bahwa sistem telah berjalan dengan baik meskipun hasil prakiraan masih memerlukan perbaikan, terutama data curah hujan yang digunakan (baik data pengamatan maupun data prakiraan). Penggunaan hujan prakiraan dapat menghasilkan lead time yang lebih panjang, tetapi akurasi prakiraan model menjadi berkurang.

Abstract

The infrastructural plans in the Jakarta Bay to reduce risks of flooding in Jakarta city comprise a large sea dike that encloses a retention lake. Part of the planned dike has the shape of the iconic Garuda bird. This shape is based on NCICD Stage-B Master Plan, where the form shape has not been tested on hydraulic perspective. Therefore, testing of wave run-up has been investiagated to find the optimum form of the Garuda Shape. The simulation of wave run-up uses Hawassi Model, where the model is governed by Boussinesq wave equation with considering wave-wave interaction. This paper shows that if in the future an explosion of Anak Krakatau will occur with strength 1/4th of the original Karkatau 1883 explosion, wave crests of 11m and troughs of 6m may collide against the birds head. As an alternative example, a more optimized design of the dike is constructed that reduces the maximal wave effects considerably.

Abstract

The aim of this resistivity logging measurement is to decide the stratification of rock and distribution ofaquifer based on the resistivity value. The objective of the well logging is to determine the depth and thicknessof aquifer for well construction, in order to decide the position of screen in the aquifers .Interpretation resultsof the resistivity logging of aquifer of sand and sandy tuff vary between 20 40 ohm-m and 60 115 ohm-m forbreccia. Groundwater in the Ciparay and Cibodas areas is predicted in the depth of 42 66 m and 75 108 m,consisting of intercalation of young volcanic fan and Bandung lake deposit. The aquifer in Dago area is lessthan 100 m deep representing young volcanic deposit including the Cibeureum Formation, whereas aquiferswith a depth of more than 100 m comprise volcanic deposit, including the Cikapundung Formation. It isrecommended to extract groundwater from more than 50 m deep, in order to prevent influence to phreaticaquifer as excavated well. The minimum kind of well logging for groundwater drilling should consist ofresistivity, self-potential and gamma ray logging.

Abstract

Bengawan Solo Hilir yang terletak di Wilayah Provinsi Jawa Timur memiliki sumber daya strategis, yaitu sebagai pemasok air yang sangat besar di Jawa Timur. Di sisi lain permasalahan yang terjadi di Bengawan Solo Hilir adalah banjir pada musim hujan dan kekeringan pada musim kemarau. Oleh karena itu diperlukan upayaupaya untuk penanggulangannya. Salah satu upayanya adalah dengan memanfaatkan rawa Jabung sebagai waduk retensi yang dilengkapi dengan inlet dan outlet, dikombinasikan dengan pembangunan bendung gerak Babat (Babad Barrage) dan saluran pengelak banjir (flood way) Sedayu Lawas yang berfungsi untuk mengalihkan sebagian debit banjir Bengawan Solo dialirkan langsung ke Laut Jawa. Dengan ketiga fungsi bangunan pengendali banjir tersebut diharapkan mampu mereduksi banjir di Bengawan Solo khususnya bagian hilir. Namun saat ini dengan kombinasi bangunan air tersebut di atas belum mampu mereduksi banjir sebagaimana yang diharapkan. Maka diperlukan usaha untuk meningkatkan kapasitas debit aliran salah satunya melalui saluran banjir Sedayu Lawas dengan jalan memodifikasi inletnya.

Abstract

Mangroves in Indonesia have a large enough area, but in the last 3 decades the area has been reduced to 40%. Besides having a function as a coastal protector, mangroves are also able to maintain the quality of the waters around it. Currently, the construction of a reclamation island in Jakarta Bay is being carried out which will have an impact on the surrounding mangrove forests. Therefore, the purpose of this study was to identify the impact of island reclamation in Jakarta Bay on sedimentation and mangrove growth in surrounding area. This research was conducted with literature studies, vegetation analysis, water quality analysis and also spatial analysis with WorldView-2 satellite imagery. The results showed that the mangrove forests on the coast of North Jakarta, especially in the Muara Angke area tend to increase, especially in the reclaimed island area. The mangrove stands increase by approximately 1.32 ha / year. The density and stem diameters vary in 5 locations. Oxygen levels at the study site are very low but the existing mangrove forests can absorb dissolved heavy metals. The results of the study also show that the area that has the potential to be planted with mangroves is 30 ha. Overall, the sedimentation process helps expand mangrove forests naturally while the bad quality of water does not significantly affect the development of mangroves. On the contrary, the existing mangrove is able to keep the stability of the  water quality in surrounding area.

Abstract

The Tilong Reservoir located in Kupang District, has 154.97 ha surface area with an average depth of 12.5 m, water volume is 19 million m3 and water discharge around 86.4-106.3 m3/day. The main function of this reservoir is for irrigation. Capture fisheries activity has not been optimally developed. The development of capture fisheries can be done through culture-based fisheries (CBF), namely milkfish (Channos channos) or tilapia (Oreochromis niloticus) stocking. The aims of this study is to determine the potential of fisheries production and the seed needs for CBF development in the Tilong reservoir. The study was conducted in March and September 2016 at three observation stations. Water sample was taken at 0.5 and 2.0 m from the surface which is the euphotic depth. The results showed that CBF activities in the Tilong Reservoir could successful because supported by the limnology conditions was suitable for fish life, the availability of seeds produced from hatchery was sufficient for stocking and support of local communities through local wisdom. Fish seeds are produced by 13 hatchery which are capable of producing milkfish and tilapia seeds of 7,040,770 and 7,023,400 per year. Based on these aspects, capture fisheries through CBF are feasible to be developed in the Tilong Reservoir. The fisheries production potential in the Tilong Reservoir ranges from 75.9 to 77.5 kg/ha/year or 11.9-12.0 tons/year. The optimal number of milkfish and tilapia seeds that can be stocked ranges from 71,000-73,500 individuals/year and 72,000-75,000 individuals/year respectively. The fish production estimated from stocking was about 40% of the potential production with economic value of Rp 20,500,000 and Rp 21,500,000.

Abstract

North Coast of Java Island continues to experience coastal dynamics which resulted significant coastline erosion problems. According to the Ministry of Marine and Fisheries data (KKP), from 100 locations of coastline erosion in 17 provinces of Indonesia, North Coast of Java Island suffered the worst erosion, reaching 745 km or 44 percent of total coastline length. The shoreline retreat can be caused by three factors: sea level rise, erosion and land subsidence. The aim of this research was to determine the correlation between sediment equilibrium in coastal cells and the initial hypothesis of land subsidence which caused a coastline retreat. The method to calculate sediment equilibrium uses  hypothetical sediment budget model. Modeling itself is done along the North Coast of Java. LITDRIFT model of Longshore Sediment Drift is employed to assess the coastline profile. The result of the research shows that there is anomalous model that is the condition of sediment is surplus but the condition of the field is backward. Several locations experienced a sediment surplus but experienced a coastline retreat, and after comparison with field observations and secondary data there was evidence of land subsidence: Pondok Bali Beach, Randusongo Beach, Muara Reja Beach, Depok Beach, Slamaran Beach, Jeruksari-Mulyorejo Beach and Sriwulan Beach. Furthermore this result can be used as an initial indicator of the land subsidence causing the coastline to retreat. In order to solve the erosion and sedimentation problem, the detail study with more comprehensive parameter needs to be conducted.
