Journal of Civil Engineering (eISSN 2579-9029/pISSN 2086-1206) is a new journal that preceded by the previous Civil Engineering Department ITS Journal which was well known as Jurnal Teknologi dan Rekayasa Sipil (TORSI). TORSI journal was established in March 1981. In 2009, TORSI journal name was changed to Journal of Civil Engineering. Journal of Civil Engineering is managed by Pusat Publikasi Ilmiah LPPM Institut Teknologi Sepuluh Nopember (ITS). Journal of Civil Engineering published at least five papers for each volume. Annually two volumes are published with the first volume is published within the period of January-June and the second volume is published within the period of July-December.

Abstract

Reclamation fill requires material to fulfil the particle gradation requirements as follow : gravel 30% max, sand 50% min, and silt-clay 20% max. Generally, field officer wants to know the density degree of material when it has arrived in the field immediately and easily by using sieve testing. Water content changing caused by rainy season and tidal, taking the largest part of affecting the density and strength of soil. This laboratory test research is using material taken from quarry river, shores and hills which have requirement as follows: silt-clay 20% max, sand 80% min, and gravel which has represented by sand. This material is tested using sieve and hydrometer to determine Cu (coefficient of uniformity) and Cc (coefficient of curvature). Next step is to dense using Modified Proctor and Direct Shear testing with saturated water value (on Zero Air Void line) and non-saturated (on wopt). Research result shows the bigger the Cc/Cu value is (soil is more homogen), maximum dry density will become smaller, dmax (dmax = -0,808.Cc/Cu + 2,061) and also the optimal water content will become bigger, wopt (wopt = 7,512.Cc/Cu + 9,492). The bigger the Cc/Cu, cohesion effectiveness value(C’) and effective internal angle friction ') will become smaller. Non-saturared condition is showing bigger value ( C’ = -0,088.Cc/Cu + 0,087 and ' = - 29,886.Cc/Cu + 53,309) than in saturated condition ( C’ = -0,057.Cc/Cu + 0,072 and ' = -33,052.Cc/Cu + 48,761) for the same Cc/Cu value. Similarity between these parameters is only valid if reclamation fill material composition used are as follow: sand 80% min, silt-clay 20% ax, and Cu limit of 1≤Cu≤50.

Abstract

Static load of construction element is the most general problem at civil constructon design, the use of bamboo as subtitution of agregate is the one of solution to reduce unit weight and static load of construction element. Based on consideration of structure analysis, bamboo is suitable as alternative of construction material. Focus of the research is type of bamboos fiber that used as concrete mix. The research observations consist of unit weight, compressive and cracking strength using flowing concrete method. The research using bamboos fiber at proportion 0/100% (Normal), 20/80%, 40/60%, 60/40%, 80/20% and 100/0% of conventional agregate. The speciments shape is concrete cylinder (15 cm diameter and 30 cm height) and speciment identification and cracking strenght be perform after 14 days treatment. The result of reasearch indicate decrease of cracking strenght and non linier relationship strength-strain characteristic.

Abstract

The research is motivated rationale for reuse styrofoam waste (wrappers monitor) that is widely available on the ground that this cannot be destroyed or recycled. Utilization of waste is intended to not pollute the environment and can even be commercially valuable. In addition, this study is an attempt to find alternative materials replacement bricks. One of them is by using a mixture of portland cement, silica sand and styrofoam for the manufacture of non-structural lightweight concrete. Silica sand crushed into powder 22.44% retained on sieve no. 325 and styrofoam used in the form of small granules which pass 9.5 mm sieve. This study begins with a test mortar with silica sand content of 0%, 30%, 40%, 50% by weight of cement + silica sand. Then one of the mortar mixture composition is taken to be combined with Styrofoam to test concrete with styrofoam levels of 3%, 3.5%, 4% by weight of cement + silica sand. From the results of testing mortars, the composition of the mixture is taken as 40% silica sand and cement 60%. In testing the concrete, the greater the level of styrofoam, the smaller the volume weight, compressive strength, tensile strength and flexural strength concrete. The composition of concrete mixtures with styrofoam levels 3.5% and 4% which can be categorized as non-structural lightweight concrete material to be used as wall panels / insulation.

Abstract

Self-compacting Concrete (SCC) is an innovation of concrete that does not require the process to occupy formwork vibration (Placing) and compacted (compaction). SCC is able to flow under its own weight, unable to meet or fill formwork (formwork) and reached its highest density. SCC requires a mineral Admixture fly ash and chemical form of Viscocrete a high viscosity in order to meet the specified flowability, whereas other compounds are iron slag waste from steel mill wastes in the form of fine aggregate. Trial mix performed on materials such as fly ash, mineral Admixture fly ash, silica fume, chemical Admixture Sika is viscocrete 10 from Indonesia, and the material is a mixture of iron slag from PT Ispat Indo to determine the optimal composition and meet the requirements of filling ability, passing ability , viscosity and segregation. Tests using the slump cone filling ability, passing ability to use L-box, while the viscosity and segregation using the V-funnel. Compressive strength testing performed with a cylindrical test piece 10 x 20 cm at the age of concrete 3.7, 14, 28 and 56 days. With as many as 495 test specimen for the test object 33 composition of concrete mix design. Each dose was given viscocrete composition from 0.5 to 1.8% by weight of cementitious according to the dose required by Sika Indonesia. While the dose of Silica Fume composition using 0%, 10% and 20% of fly ash pozzolan. The final aim of this study are expected to obtain the optimal material composition of the mixture by generating a maximum compressive strength and price efficient as well.

Abstract

Implementation of OHS management system by construction companies in North Sulawesi has many problems. These problems are identified as inhibiting factors. This study aims to identify inhibiting factors that influence OHS implementation on construction company and how public policy alternatives that can be proposed. Product moment correlation analysis results showed overall effect of those factors, of which the most influential factor is budgetary project planning. Proposed Public policy are: procurement of equipment and materials budget should be included in Cost Expense Plan for construction works; monitoring mechanisms need to be regulated in order to create awareness OHS implementation, including governing authority to the field of OHS in related agencies. Similarly, the rules of reward and punishment to promote awareness of OHS implementation, OHS socialization also be performed periodically, with various forms and methods and direct guidance in the field, establishment of OHS tools and materials management unit.
