Abstract

Serang Watershed is a region dominated by steep slopes and high rainfall. This causes the region to have a high erosion potential. Water resources conservation activities in the upper watershed of Serang Watershed have been started with the construction of a number of conservation infrastructure. However, until now these efforts have not been assessed properly. This is because the existing institutional system is not functioning properly. This research discusses the strategy of conserving water resources activities in the study sites by Soil and Water Conservation Groups so that it is expected to overcome erosion problems at the research sites so as to improve the welfare of the community in the Serang watershed, especially Sampetan Village. Research method using questioner, interview, field survey, literature study, and SWOT analysis. Based from the analysis it can be concluded that by using the slovin formula, the number of respondents used as sample is 96 people from the population of 127 people consisting of various stakeholders including Village Government, Local Government, KKTA, and Community Leaders. Using SWOT method is analyzed external and internal factors of forestry and institutional resources of Sampetan Land and Water Conservation Group. Keywords : Erotion, Conservation, Institutional, SWOT.

Abstract

Land subsidence is a natural phenomenon that occurs in the young soil layer (alluvial). The incident is bad for the construction that is above it, it is also exacerbated by the entry of seawater that enters due to the soil surface that has been declining so that the ground elevation is below sea level elevation.Semarang city is one of the cities located in the north of Java island that the condition of the land in the city is alluvial soil. Semarang's coastal topography is flat in the range of 0-2% with most of its area almost equal to sea level and even in some places below it. The results of technical geological investigation in North Semarang city showed that the subsurface layers up to 25 m depth consisted of heavier soil types 1.7-1.84 t / m3, silt with 0.200 0.448, & clay. The predictions of subsidence using the 1D Terzaghi approach with the T90 obtained the smallest decay of 19.6 cm over 8,624 years and the greatest collapse 127.7 cm for 29.634 years, while using the smallest 216 cm subsidence Geostudio program for 8,624 years and the greatest descendant of 135.9 cm for 29.634 years.

Abstract

Semarang city is geographically consisting two units of morphology, namely: in the southern part is a denudasional structural hills consisting of Tembalang, Tanah Putih, Tegalsari, Siranda, until Gajah Mungkur. While the alluvial plain lies in the northern part. Land subsidence in some parts of Semarang city becomes a serious problem, because the area is generally a settlement area. As a result of land subsidence, settlement areabecomes lower, because the settlement location partly close to the beach, during a tide it overflows into the mainland through rivers and drainage canals and then it pooled to the settlement. The purpose and goal of this study is to assess and predict the large and length of land subsidence on alluvial plain due to the load and the mechanical properties of the soil as well as to assess and predict the changes of the inundation width in the alluvial as a result of land subsidence. This research use experimental method. To test the analysis of alluvial sediment subsidence, it is obtained by the calculation based on samples and primary data in the laboratory. The calculation is done in two ways, the first way is calculating the physical model with 1D Terzaghi, while the second way is predicting the subsidence using PLAXIS software and the result is the prediction of the large and length of subsidence with load variations and different soil mechanical conditions. Furthermore, comparing the calculation result using a physical model with the calculation result using PLAXIS software to get the final result of how is the large and length of land subsidence and the tendency of the subsidence. Whereas to calculate the width of the inundation, it is planned the changes of the inundation width using GIS software (Geographic Information System). The result of this study which applies 1D Terzaghi approach, obtained the smallest subsidence is 64,2 cm for 17,781 years and the largest subsidence is 107.600 cm for 29,635 years. While the approach which applies PLAXIS software obtained the smallest subsidence is 65.8 cm for 17,781 years and the largest subsidence is 110,000 cm for 29,635 years. The subsidence tendency more northern is larger and the time is longer. Land subsidence in the alluvial plain continues to rise, therefore the inundation in the settlement that located close to the river and the beach continues to grow wider, between 2016 and 2045 there is additionalinundation of 493,63 Ha. Keywords: Alluvial, Subsidence, Inundation, GIS, PLAXIS

Abstract

The availability of water in the increasingly rare dry season and the tendency of floods in the rainy season, is a problem that can not be solved completely in various regions in Indonesia. The construction of reservoirs is generally aimed at helping to overcome the problem of increasing water resources needs from time to time. The area of Kudus Regency is an area with relatively limited water resources. Therefore it is necessary to plan the construction of Logung dam in the hope that the surrounding ground water can be maintained, the forest can be grown, and in the end can preserve the existing water source. The aim of this research is to get an overview of Logung Dam plans that are economically feasible both from cost aspect and benefit aspect. To find out the feasibility of Construction of Logung Dam in Kudus Regency, Net Present Value (NPV), Internal Rate of Return (IRR) and Net Benefit Cost Ratio (Net B / C) will be performed. Keywords: economic feasibility, Logung dam, Kudus regency

Abstract

In this condition, cities with coastal area have soft clay soil. The main problem is that the soft clay soil has bee n suffering from great settlement due to consolidation that makes the buildings around become instable, it causes the landfill is done on the soft soil. Suppose the consolidation happens naturally as it is, it will run in a relatively longer time, years or even decades. In order to be stable, it needs longer time, as consequence, the soil is not able to be used for building to which it will give damage in term of time and finance. It is why engineering is needed to fasten the consolidation process in order to make the soft clays soil able to be used efficiently. One of particular methods to fasten the consolidation process is building vertical drain. There are many ways and materials that can be used to set up vertical drain, among which are making small holes through drilling then filling it up with porous materials such as sand and gravel stone or coir. Nowadays, new method has already been available to fasten the consolidation process by geosynthetic. It is Prevabicated Vertical Drain made of polymer material. The use of geosynthetic for vertical drain can fasten the consolidation process significantly. The speed process of consolidation depends on the types of soil and model of the vertical drain as well as the distance among holes. Vertical drain can only accelerate the settlement due to consolidation, but it does not minimize it. By applying the drain model, time for the soil settlement can possibly be arranged that makes the soil of reclamation more ready for use. Keywords: consolidation, vertical drain, goesynthetic

Abstract

Water is an essential ingredient for food availability, health and survival. Dams is one form of building in an effort to conserve water resources. The Randugunting Dam Development Plan in Blora Regency enters into 65 priority Dam in NAWACITA. Then to determine a project is feasible to be implemented or not, feasibility studies should be undertaken so that the business or project that is run not be in vain in the future. Any proposed public or private program or activity that is beneficial to the public interest and will result in an impact on 200 or more persons and requires compensation, it should be supplemented with a Land Acquisition and Resttlement Action Plan (LARAP) the policy covers: 1) Land acquisition and / resettlement should be avoided or minimized as far as possible; 2) If procurement of land is inevitable, the compensation provided and the transfer of the PAP should be accompanied by coaching efforts; 3) WTD receives appropriate compensation based on calculated replacement cost of affected assets; 4) In determining the amount of compensation value should be based on consultation and discussion with WTD. The cost components of the Randugunting Dam Development include pre-construction costs (land planning and acquisition / LARAP), construction costs and maintenance operation costs. Benefit components are viewed from the parties concerned with the project, especially for people in need including agriculture, fisheries, raw water, flood control, electricity and tourism. Development cost of Randugunting Dam with investment of Rp. 861.714.687.361 for 50 years. In view of the calculation results, NPV can be concluded of 139.866.838.506> 0 then the NPV is acceptable. The rate of return with the interest rate of 11.63% then the value of IRR of 11.63%> of DF = 10.49% so that investment is feasible. With the age of 50 years reservoir with the value of BCR of 1.16> 1 then the dam construction is feasible. BEP (Break Even Point) of the analysis produces BEP in the 30.4 year.
