Abstract

This research will observe the effect of water content and compaction effort to the hydraulic conductivity of Karang Pilang Surabaya Clay used for clay liner of municipal waste disposal area.In this research, clay was taken from Karang Pilang, Surabaya.  Clay was compacted with Standard Proctor and Modified Proctor Tests.  From each of them,five sample were prepared at different water content (wc apt),2 (two) at wc<wc apt (wet side).  In order to obtain the hydraulic conductivity (k) of the clay liner, falling head test using 0.005 N CaSO4 was carried out.The result showed that hydraulic conductivity of compacted clays with the increasw of water content until ± 4 % over wopt.  The hydraulic conductivity of compacted at wit side is lower than the clay compacted at dry side.  The increase of compaction effort increasing density of clay results in the increase of hydraulic condctivity significantly.  For different clays, higher density does not assurance lower hydraulic conductivity, the hydraulic conductivity is also influenced by plasticity of clays.

Abstract

This paper discusses the soft clay soil stabilization with lime on the condition of the water content of the field. The sample used is soft clay of Marabahan, Barito Kuala, South Kalimantan. The water content of the sample is initially 76.2%. Samples were mixed with natural limestone that has been crushed and screened through a sieve No. 20 the percentage of 4, 8, 12, 16, and 20 percent based on the dry weight of the sample. Samples were mixed with lime cured for 7 and 14 days. Some of the tests performed in the laboratory include testing soil plasticity, direct shear tests, unconfined compression test, vane shear test, consolidation, and CBR. The results showed a decrease in the values of soil plasticity (liquid limit and plasticity index) and soil compression parameters (cc and cs) with the increased percentage of lime. While the values of cohesion, friction angle in, qu and qr, and CBR increases with increasing percentage of lime. The results also showed that the curing time effect on soil parameters were mixed lime.

Abstract

This research focused on the effect of leachate from municipal waste disposal are (WDA) on the chemical constituents of the clay liner with varies water content. In this research, leachate was taken from Sukolilo WDA and clay for clay liner was taken from Karang Pilang, Surabaya. Clay was compacted with modified Proctor tests. From each of them, samples were prepared at different water content, those are; at optimum water content (wc opt), at wc<wc opt, and at wc>wcopt. Falling head test using 0,005N CaSO4 was carried out. The k value was determined when the hydraulic conductivity was constant. Afterwards, the liquid was replaced with the leachate. Chemical constituents of clay liner were obserbed before and after test. The results show that most of the chemical constituents of clay liner, which permeated by leachate, increase corresponding to the dominant constituent of the leachate. This change is influenced by water content of the clay liner.

Abstract

The purpose of this research is to know the influence of composition of mass fraction between filler and matrix to mechanical strength of composite material utilizing fibers fiber (arenga pinnata) as filler with polyester resin matrix, composition of fiber fraction mass and polyester resin is 30%:70%, 40%: 60% and 50%: 50% with fiber angle orientation: 0; 0; 0; 0, using the Hand Lay Up making composite methode. Impact test is done with ASTM D5942-96 standard and Tensile Testing is done with ASTM D638-03 standard. Impact test results show that all composition of mass fraction have value Energy impact above Energy impact Cover Body Motorcycle Brand X used as comparative material, 50%: 50% mass fraction composition yield the highest impact energy value equal to 198,75 Joule / cm2. Tensile Test showed the composition of mass fraction 50%: 50% yield value of tensile strength equal to 27,09 MPa is the value of tensile strength most closely to value of tensile strength of comparative material of 30,24 MPa, Tensile Test also shows all composition of mass fraction have the percentage of length increase above the percentage of comparative material, the composition of 50%: 50% mass fraction yields the highest percentage of 4.02%. This research concludes that fiber composite material (arenga pinnata) with 50%: 50% mass fraction composition is feasible to be used as an alternative material Cover Body Motorcycles.

Abstract

Student dormitory is one of the facilities provided as a means of support for the students in their studies in Universities. Because many students who come from outside the region where the study was held. Dormitory students have an important role in supporting the successful development in the field of education as well as business opportunities to boost the economy of the people who live around educational institutions. However on the other side where the hostel will generate waste, among others, feces and urine, organic and inorganic garbage and domestic waste which if not managed properly could potentially cause health problems, and aesthetics. The problems that have been faced by managers and occupants of a student dormitory in the Kelurahan Sungai Besar, Kecamatan Banjarbaru Selatan, Banjarbaru City is the lack of knowledge of how the processing waste human manure, organic waste and domestic waste water so it does not pollute the surrounding environment and at the same time converting the processed organic waste into a resource new energy, namely biogas and compost.Digester technology applications will generate a set of tools Human waste processing manure, organic waste and domestic waste. This technology is the processing of organic material anaerobic digester technology in the form of organic waste that the waste that comes out of the digester safely discharged into the environment. Aside from being a waste treatment plant, the solution can also produce biogas to biogas formed later expected to be utilized as a fuel substitute for LPG and fuel Generator Set (Genset) as a substitute fuel (gasoline) in addition produce a byproduct of compost were also no less economic value. Inside the digester hydrolysis and fermentation process occurs, phase Acetogenesis and methanogenesis phase of organic waste into biogas and its byproducts are composted. The process takes 20-30 days. Wastewater digester output of the reactor is no longer harmful to humans, the environment and other living organisms that are not harmful to the environment if disposed of.
