<![CDATA[Construction Services Law is a statutory regulation that is used to regulate all matters involving construction services, whereas in this study conducted in Jakarta, Indonesia, Law No. 18 of 1999 about Construction Services and Law No. 2 of 2017 about Construction Services. With changes in the Construction Services Law, there are differences in the form of revisions, additions, and reductions. These differences and changes are analyzed with the aim of developing a better Construction Services Law in the future. The method used in this research is a literature study method and questionnaire survey method. Questionnaire questions were formed based on literature studies from previous research and Construction Services Law discussed in this study. Data obtained from respondents were entered into the IBM SPSS Statistics 23 program and then conducted a validity test, reliability test, correlation test, and regression analysis. The analysis shows that there are several Construction Services Law’s regulations which cannot be a good guide for construction service providers and users yet, due to: the provisions regarding building failures are not well explained, the general lack of provisions governing the selection of expert assessors, the lack of clarity governing labor standards construction work and unclear regulations regarding sanctions for parties involved in construction work.]]>

<![CDATA[Maintenance of good and sustainable irrigation ponds have an impact on ensuring the sustainability of the irrigation system. For this reason, it is necessary to develop a reservoir maintenance model based on multicriteria analysis relating to the type of maintenance. The method used Structural Equation Model (SEM) with the WarpPLS approach. The criteria used Structural Stability, Economy / Finance, and Physical & Environmental. The findings obtained variable structural stability has a very significant effect on the maintenance of irrigation ponds (r <0.01 and β = 0.73). Economic / financial variables have not significant effect on reservoir maintenance where r = 0.3 and β = 0.03. Physical and environmental variables also did not directly influence the maintenance of ponds with r = 0.29 and β = 0.03. However, the physical & environmental variables significantly influenced structural stability with r <0.01 and β = 0.32. Physical and environmental variables also significantly influenced economic/financial where r <0.01, and β = 0.45. This finding supported various previous studies for structural stability variable but different for economic/financial variables that did not significantly affect by the determination of reservoir types.]]>

<![CDATA[Delay in the implementation of the project often occurs due to various risk factors that have not been identified during project implementation, so that the impact on project delays and unexpected costs increases. However, each construction project has different risks, becaused the environmental conditions of the project, so that it requires handling different methods of project implementation. This study aims to: 1) analyze the risks that could potentially occur during the construction of the log dock extension; 2) Appropriate Handling Methods for the Implementation of the Log Dock Extension Work. The research method is done by identifying the risks that occur in the field and with the interview method about the possibility of possible risks that occur. The results of the study indicate five high-risk categories according to the perception of service providers that most influence on project delays. These risks include unpredictable external phenomena, such as tidal elevations that exceed plan, resulting in changes in design and method of implementation. The conclusions of this study include that the application of risk management to the implementation of the log dock extension project at the port of Tanjung Emas Semarang needs to be applied to minimize delays and reduce unexpected costs.]]>

<![CDATA[Zonation of liquefaction potential is the important thing in understanding the liquefaction impact on an area. The liquefaction Severity Index (LSI) method can be applied to determine the liquefaction vulnerability level. This paper presents a study of liquefaction using LSI method to compose the liquefaction vulnerability map in a coastal area of Bengkulu City i.e., Lempuing Subdistrict. This study was conducted by analyzing CPT data in Lempuing Subdistrict to obtain the Factor of Safety and the probability of liquefaction. Peak Ground Acceleration (PGA) was assumed as 0.5g, which refers to SNI 03-1726-2012. Furthermore, the value of liquefaction probability and factor of safety obtained was analyzed to obtain LSI index and adjusted to the specific categories i.e., very low (0<LSI<15), low (15<LSI<35), moderate (35<LSI<65), high (65<LSI<85), and very high (85<LSI<100). Based on the analysis result, Lempuing Subdistrict was categorized as a very high to the very low susceptible area to liquefaction. The very high susceptible area was located on the eastern Lempuing Subdistrict bordering to the Gading Cempaka Subdistrict. The high susceptible area was located on the northern Lempuing Subdistrict bordering the Tanah Patah Subdistrict. Moderate to very low susceptible areas were located in the middle, west, and south of Lempuing Subdistrict.]]>

<![CDATA[All of the full-scale tests and numerical analysis of Nailed-slab System from previous researchers used massive reinforced concrete piles. This research will study the possibility of steel pipe pile as a replacement of massive reinforced concrete piles if there are available enough steel pipe piles. This research is aimed to study the behavior of single steel pipe pile Nailed-slab System on soft clay and the influence of pile length due to slab deflection and soil stresses. It was used the data from Puri (2015a) for a single massive reinforced concrete pile Nailed-slab. This massive reinforced concrete pile was replaced by a single steel pipe pile with similar and varied diameter which analyzed by the 2D finite element method. Results show that the steel pipe pile can be used as a “nail†at the Nailed-slab pavement system but by a larger dimension compared to the massive reinforced concrete pile. The maximum effective shear stress in soil did not reach undrained shear strength under a standard wheel load 40 kN. Generally, the soil was not failure.]]>

<![CDATA[LVL Sengon and concrete can be used to form a composite structure of the floor system. Connections between LVL Sengon and concrete on this composite floor system are the weakest part so that a majority of structural damages are concentrated at these joints. This study discusses the lateral resistance of lag screw joints in a composite system of LVL Sengon and precast concrete. The lateral joint resistance was evaluated through quasi-static loading upon double shear test specimens having two screws at every single shear. Variation of the specimens includes precast concrete compressive strength of 20.71 MPa and 25.29 MPa, screw diameter of 6 mm length 101.6 mm and 8 mm length 101.6 mm and 127 mm, and angle of lag screw axis against the wood fiber of 60° and 90°. The result shows that lateral resistance of the test is greater than that of EYM, SNI, and EC5 predictions. Joint failure in this experiment is due to failure in wood fiber along with the occurrence of one up to two plastic hinges in the screw.]]>

<![CDATA[The most common problem with drinking water supply is Non Revenue Water (NRW). NRW can be grouped into two types, namely physical water loss and non-physical water loss. This study aims to determine the NRW size, NRW causes, counter measures that can be done to suppress NRW. The results of evaluation of distribution networks that occur in the Blahbatuh City Zone District Meter Area (DMA) PDAM Gianyar. The difference between the amount of water distributed and the amount of water recorded in the account is NRW. The way to find out the cause and control of NRW is to analyze the results of the step test, UFM test (Ultrasonic Flow Meter), and conduct the interviews with employees of PDAM. The evaluation of distribution networks is only done in DMA Pande that has completed data. The amount of NRW that occured in the Blahbatuh City Zone is 474,142.83 m3/year (59.91%). The water loss is caused by damage to pipe accessories, leaky pipes, inaccuracies in the accuracy of the water meter. The water loss can be overcame by establishing a DMA, replacing pipe accessories, calibrating and replacing water meters. The evaluation results for the existing conditions of the distribution network in DMA Pande of Blahbatuh City Zone have not worked optimally. It seen from the results of the waternet and from the number of SR’s that have not met the requirements for the formation of a DMA.]]>

<![CDATA[One of many buckling modes that could occur on the beam is lateral-torsional buckling. Lateral torsional buckling could result in lateral deformation and torsion of section. In the AISC 360-16 Spesification, an equation is provided to calculate lateral-torsional buckling critical moment of prismatic I section beam. For cellular beams (I section beam with circular openings), AISC Design Guide 31 states that the lateral-torsional buckling critical moment should be checked in accordance with AISC Specification using gross section properties. With this assumption, thus, the design guide ignores the existence of circular opening on the web, which can cause a reduction of lateral-torsional buckling critical moment. In this study, lateral-torsional buckling analysis on cellular beam with simple support loaded by distributed transversal load has been done - the analysis utilized finite element based software. From the analysis, the critical moment is lower than AISC 360-16 critical moment with the assumption of prismatic I section beam, with the maximum difference percentage of 43,58%. Based on this study, a correction factor has been obtained to estimate the critical moment of cellular beams by using equation on AISC 360-16. ]]>

<![CDATA[One of the problems with peat soils, when subjected to imposed loads of construction, is the very high compression and long-term excessive settlement. The embankment can be built on peat soil, but it needs reinforcement that can contribute to increasing the stability of the embankment. The nailed slab system, as reinforcement, is expected to reduce settlement and increase the stability of peat soil. The aim of this paper is to study the effect of pile length and distance on the reduction of settlement in both monolithic and non-monolithic piles. The embankment load test was conducted on 70 cm x 120 cm plates, which were reinforced pile with different lengths and distances in the peat soil layer. The analysis was conducted on the reduction settlement of monolithic and non-monolith pile. The results showed that the length and distance of the pile had an effect on the reduction settlement. Changes in pile length are more dominant reducing settlement compared to changes in pile distance. Pile connection with slab has a significant effect on different lengths of piles than different distances piles.]]>
