<![CDATA[The contradictive one on landfill for municipal solid waste is about cover system. For many landfills in Indonesia that commonly using controlled landfill system, where waste is filled into landfill and being covered by soil every few days. The covering with soil, especially for sanitation usage. The problem, the soil that used as a cover layer have a much bigger unit weight charasteristic than the unit weight of the waste itself. There is a stability problem here, evenly the unity between soil and waste, failure of cover layer, also the soil character that is so sensitive to water. The increasing of moisture content will so influence to the strength of the soil. As we know, in landfill, there is so much water come from wastes leachate, and also from precipitation. Degraded waste is one of the alternative material that can be use as a cover. The light unit weight and hidraulics character that like silt, are the advantage factors from degraded waste.]]>

<![CDATA[This paper deals with the modelling and simulation of flood inundation characteristics i.e. boundaries, depths, and velocities within Sekanak Subsystem which is one of flood-prone areas in Palembang City, Indonesia. The area of subsystem being studied was about 11 km2 . The new hydrodynamic model, HEC-RAS 5.0 was used to simulate the flood flow regimes by integrating the one-dimensional and two-dimensional model, known as combined 1D/2D flow model. The geometry of drainage channel was used as 1D domain to simulate the flow routing along the channel based on certain boundary conditions i.e. 25-yrs flood discharge and tide level both in upstream and downstream. The 2D domain in the model was the geometry of area beside the channel. The flow of 1D and 2D domain were connected by lateral weir, so the water which overflowing from the channel could be routed within 2D areas. The result shows that the area of inundation during lowest tide level is about 3.43 km2 with the velocities and depths range between 0 â 1.18 m/s and 0 â 3.08 m respectively. Furthermore, for average tide level, the area of inundation increases to 3.54 km with the velocities and depths range between 0 â 1.30 m/s and 0 â 3.11 m respectively. The maximum potential of inundation during the highest tide level is about 4.46 km2 with the velocities and depths respectively range between 0 â 2.64 m/s and 0 â 3.40 m. Therefore, it can be concluded that almost half of subsystem area potentially being inundated (40.11%), so it requires appropriate flood control and management to reduce the risk.]]>

<![CDATA[Modification technology of castellated beams of Wide Flange beam (I WF) are now varied, starting from addition high beam variation so that moment of inertia larger than origin beam, until the hole dimension variation for the aesthetic and mechanical-electrical installations. In the castellated beams design should be noted weakening effect shear forces and buckling due to the hole modified. This study was to determine the behavior of castellated beam with hexagonal holes dimensional variations using the finite element method. The method in this research is to create a numerical model of the castellated beam 225x75x7x5 mm span of 1 meter with a hexagonal hole openings using the finite element method are verified first by the results of an experimental model. Geometry, material properties and loading both models are the same. After the numerical model results closer to experimental model results, then made 9 other castellated beam numerical models with variations in the dimensions of the hexagonal holes. The results showed that the higher and the wider hole so the larger tensile stress and compressive stress. Deflection is proportional to tensile stress and compressive stress. The smaller the ratio of the hole and holes number so the smaller the shear stress.Key Words: castellated beam, finite element method]]>

<![CDATA[Sistem pengangkutan sampah berhubungan dengan biaya dalam pengelolaannya. Semakin jauh rute pelayanan dan semakin banyak jumlah ritasi truk maka semakin besar pula biaya operasional yang harus dikeluarkan. Dari pengamatan yang telah dilakukan, TPS-TPS di wilayah Seberang Ulu kota Palembang berjarak cukup jauh dari TPA Sukawinatan. Hal ini mempengaruhi waktu pengangkutan dan biaya angkut sampah. Sistem pengangkutan sampah di wilayah Seberang Ulu Kota Palembang menggunakan Hauled Container System (HCS) dan Stationary Container System (SCS). Hasil analisis aktivitas pengangkutan sampah didapatkan waktu rata-rata untuk pengangkutan dalam satu kali ritasi perhari dengan armroll truck adalah 2,88 jam/hari dan jumlah ritasi rata-rata per hari adalah sebanyak 2,28 ritasi/hari dan armroll truck dengan nomor lambung 81 merupakan armroll truck dengan biaya angkut sampah/m3/hari yang paling mahal yaitu sebesar Rp 15.147,2, sedangkan dengan dump truck didapatkan waktu rata-rata untuk pengangkutan dalam satu kali ritasi perhari adalah 4,77 jam/hari, dan jumlah ritasi rata-rata per hari adalah sebanyak 1,475 ritasi/hari, dan dump truck dengan nomor lambung 71 merupakan dump truck dengan biaya angkut sampah/m3/hari yang paling mahal yaitu sebesar Rp 37.281,8. Dari hasil analisis dapat dilihat bahwa nilai efektifitas yang lebih besar adalah sistem HCS dan biaya angkut sampah menggunakan armroll truck lebih murah dibandingkan dengan dump truck.]]>

<![CDATA[The development of infrastructure to support railway facilities requires innovation in materials that are lightweight, strong and environmentally safe. The biocomposite is one of the innovations in engineering technology of new materials made of natural fibers. In this study, the development of environmentally safe materials (biocomposite) was made by using bark fibers of waru trees. The waru bark fibers were analyzed by varying the compositions of treatment: 0% chemicals, 6% of NaOH, and 0.75% of silane. Afterwards, the waru bark fibers were formed using the vacuum infusion method by applying a polyester matrix. In this study, several analyses had been conducted on fiber composition, SEM, and fracture area. The results showed that the treatment of the structure of alkali-silane fibers (the content of lignin, cellulose, and hemicellulose), made the performance of materials better which had been proven by the decreased fracture area of 250.777 mm2. The waru bark fiber biocomposite materials can be applied as an innovation in developing fiber replacement materials to support railway interior facilities that are cheaper and environmentally safe.]]>

<![CDATA[This study was conducted at a factory producing construction and building materials such as ready mix concrete, piles, udit concrete, and ryol. These products are produced in almost the same process, but on different production lines. There are 2 operators in the frame reinforcement section for udit concrete production. It is seen that the two operators have the same task but different results of their work, so that the production target is not achieved. The workload analysis method is used to determine the operator's actual load. Observation of activities is carried out by the work sampling method for 5 days. In work sampling, work and idle activities of workers are observed at randomly selected times and the amount of production during observations is recorded. From the study, it is known the ideal of actual load of each operator and the number of operators for the concrete frames reinforcement. The results showed workload of operator 1 was 95.11% while workload of operator 2 was 107%. The number of operators reinforcing concrete frames remains fixed for 2 people, but wage compensation needs to be given to operators 2 for excess workload refers to the amount of wages and provisions for overtime that are applicable in the company.]]>

<![CDATA[Expansive clay has a high potential to swell if compared to other types of clay. Expansive clay also has very low bearing capacity so that a method of soil improvement was needed to improve the soil. This type of soil can be found in Gasing village, Tanjung Api-Api Km. 11 Banyuasin regency of South Sumatra Province. This research aims to study the mixture of gypsum plafond waste as additives in the process of stabilizing expansive soil clay. It can be made according to the needs of the mixture. In this study, the percentage of mixture of gypsum plafond waste are 5 %, 10 % and 15%. The test used an Oedometer (SNI 2812: 2011/ASTM D2435) equipment. By giving the pressure of 2.5 kN/m2; 5 kN/m2; 10 kN/m2; 20 kN/m2; and 40 kN/m2. The test results of the clay without mixture with gypsum plafond obtained were liquid limit value (LL) = 67%, plastic limit (PL) = 26.38% and plastic index value (PI) of 40.62%. Spesific Gravity (Gs) = 2.696, optimal water content (wopt) = 21.55 % and optimal dry weight (wopt) = 1.55 gr/cm3. Therefore, the soil sample was an expansive clay type and classified as A-7-6 (AASHTO classification). Consolidated test results show that soil compression index (Cc) = 0.190. After mixed with gypsum plafond waste of 15 %, the compression index value (cc) = 0.080. This indicates that the compression index value (cc) has decreased. Based on the above, it can be concluded that the mixture of gypsum waste in expansive clay causes soil settlement.]]>
