Authors: Putranto Leksmono Suryo , Rooswan Happmono RPX 
Published: July 2020

Abstract
As part of traffic management, Yellow Box Junction must be optimized because this marking must take precedence over APILL in traffic congestion at the intersection. The crossing performance with YBJ does have a high degree of saturation, especially from the north at Jl. Ir Sukarno - Jl. Dharmawangsa and from the west at the junction of Jl. Adityawarman - Jl. Kutai Violations against YBJ were dominated by motorbikes (90%) in terms of forcing them to enter YBJ when there were still vehicles from other approaches namely 399 vehicles/hour. Most motorists have seen the yellow square markings at the YBJ junction (75% LV, 67% MC), few know that the mark is YBJ (44% LV, 28% MC) and most respondents do not know the meaning and function that YBJ can decipher traffic jam at the intersection. Only a few respondents have ever listened to or seen a socialization about YBJ, so it is necessary to find an appropriate formula for socialization to road users.

Authors: Pranoto W A , Johan J , Vinsensisus P 
Published: July 2020

Abstract
Kapuas River is a river with a high level of sedimentation. In the process of sedimentation, one of the factors that determines the sedimentation time is the sediment settling velocity. Estimation of effective sediment deposition time could be calculated by collecting the sediment settling velocity data. A thorough laboratory research is needed to determine the value of sediment settling velocity. The analysis from the field and laboratory research showed that sediment settling velocity is related to salinity, sediment concentration, water depth, and flow velocity. This study focuses on the relationship between sediment concentration and sediment settling velocity. Laboratory research was conducted using variations of sediment concentration. The research showed that maximum sediment settling velocity with the value of 0.4133 mm/s is obtained from concentration sediment of 9380.75 ppm. Moreover, the sedimentation process will be formed faster as the sediment settling velocity increases.

Abstract
Additive Manufacturing is the formalized term for what used to be called rapid prototyping and what is popularly called 3D Printing by adding layer-upon-layer of material, whether the material is plastic, metal,.etc. Stereolithography(STL) is the standard file type used by most additive manufacturing processes. This is the file type whichwill be saved from the 3D design software package, etc.solidwork.Most commonly the slicer and the client software are combined, making the conversion from STL file3D Print straight forward and simple. Before printing a 3D model from an STL file, it must first be examined forthe errors. The errors are surfaces or facets don’t meet and facets that are too thin. Software programs such as Meshmixer, Cura and Slic3r are examples, which will correct these issues.

Published: July 2020

Abstract
Composite material is gaining acceptance for protective structures against explosion, such as granade explosion. This is due to its ligh	tness and high strength. In this paper, the response of composite plate subjected to granade explosion was studied experimentally. The composite plate was made of glass and carbon fiber with different number of plies and lay-up. The plate dimension wa 250x250 mm. The granade contains 40 grams of TNT and the shell was made of cast iron. The total mass of the granade was 365 grams. The stand-of-distance was veried, which was 300, 500 and 1000 mm. The results showed that all specimens were able to keep their integrity without collapse. The carbon fiber composites showed some small fragmet penetration, while the glass fiber composites showed no fragment penetration although some delaminations occured. The almunium plate showed fragment penetration and large plastic deformation. Therefore in this case, composite plates performed better than the aluminium plates.

Abstract
In manufacturing industries specifically in metal machining, the use of the cutting tool is important to consider. The use of the cutting tool has not been used optimally, as well as cutting parameters. In the cutting process, the wear of the cutting tool and cutting force has a very close relationship. This research was carried out to analyze the wear of coated carbide cutting tool and cutting forces produced in turning AISI 4140 steel workpieces. This study was conducted with a variation of five cutting speed levels consisting of 180 m/min, 220 m/min, 260 m/min, 300 m/min, 340 m/min and depth of cut 0.7 mm. To observe the tool wear, every 5 minutes with a maximum limit value of VB of 0.3 mm and for the cutting force values taken every 1 minute. From the results of the study obtained: The increase in the value of the cutting force is affected by the increase in wear that occurs in the cutting tool due to a change in tool geometry due to wear on the cutting tool. The highest feeding force value is at the cutting speed (Vc) 340 m / min at 368 N and the greatest cutting force value is at the cutting speed (Vc) 340 m / min at 371 N.

Published: July 2020

Abstract
Regional Metro Junction is known as a telecommunication network project which connects one city to another city / village. This project has specific quality requirement to be achieved. However, the project executor didn’t meet the quality requirement from project owner because there’s no quality guideline in the planning process of the project, so it caused several quality problem in the execution process such as 2.700 meters twisted cable, 76 poles wrong location and 35 poles tilted. In addition to that, this paper aimed to design quality metric using internal control method as a guideline to control quality the project in order to minimize the potential of rework. The step of making this quality metric is identifying the possible issue of each activity, creating the critical success criteria of each activity based on requirement documentation then identifying the resources needed of each activity. The result shows that the number of defect is decreasing as much 750 meters for the twisted cable, 44 wrong pole location and 27 tilted pole. At the end, this quality metric guideline is useful to minimize the defect of the project and can be lesson learned for another project.

Abstract
A motorcycle manufacturing company on the K56S engine has a symptom that often occurs called noise tappet. The observations found that Symptom was caused by clearence or tappet gap that was not in accordance with the specified specifications. The gap measurement system uses filller which usually relies on the experience and feeling of the operator, so it is possible to produce an unsuitable gap measurement. This research will evaluate the measurement system of clearence tappet using Measurement system analysis (MSA) which includes stability, bias, linearity, repeatability & reproducibility. Based on data processing known that the measurement system has a stable process with a linearity level of 2.6% is acceptable. The measurement system has a biased problem with an average bias value of 0.054 mm (not acceptable) and from repeatability & reproducibility with a GRR% of ANOVA method of 49.98% that exceeds the acceptance criteria.

Abstract
Traffic accidents have become a major socio-economic problem in Malaysia as it is the primary cause of mortality. Over 60 percent of these fatal accidents occurred on rural roads. Nearly half of all fatalities took place on federal roads and over a quarter happened on state roads. It is also estimated that about 2 percent of the country’s Gross Domestic Product (GDP), or approximately RM 9 billion, is lost through road accidents. Previous studies managed to develop several models for modelling the occurrence of accidents, but most of these models have plenty of deficiencies. The following study focuses on stochastic regression models, such as Poisson, Negative Binomial, Zero-Inflated Poisson and Zero-Inflated Negative Binomial with excess zero outcomes on the response variables. Furthermore, in order to specify the regression relationship with a sophisticated result, R-statistical programming is used. The method used is also the updating approach in predicting potential road accidents, which can also produce an accuracy probability of hazardous locations. Based on road accident data collected over a five-year period from 2010 to 2014 at Federal Road F0050: Kluang-A/Hitam- B/Pahat in Johor, Malaysia, results of this study show that Zero Inflated model performed better, in terms of the comparative criteria based on the AIC value.
