<![CDATA[This study will discuss the effect of temperature design with variations in air temperature between 24 ºC and 30 ºC on the life of flexible pavements. The obtained secondary field data was processed using the Nottingham Design Method. Furthermore, the results of the data processing are used to calculate the strain value with the BISAR 3.0 program (Bitumen Stress Analysis in Roads). The strain values resulting from the BISAAR 3.0 program analysis in the form of asphalt mix horizontal tensile strain (εt) and subgrade vertical strain (εz) are used to calculate the life of flexible pavements. The results of the analysis show that when using fatigue crack damage criteria, a temperature increase of 5.8% will cause a decrease in the life of flexible pavement by 0.7% (critical condition) or 0.6% (failed condition). However, when using the criteria for permanent deformation damage, a temperature increase of 5.8% will reduce the life of flexible pavement by 1.5% (critical condition) or 1.0% (failure condition).]]>

<![CDATA[Currently the mobility of the population is getting higher and higher which causes congestion and the emergence of demands to move from one place to another by using an online motorcycle taxi. Being an online motorcycle taxi driver is inseparable from physical and mental activities such as driving, controlling vehicles, carrying goods ,waiting for orders, interacting with customers, finding destination addresses, operating online motorcycle taxi applications and others. This makes the workload of online motorcycle taxi riders both physically and mentally even greater. this study aims to determine the physical and mental workload on the Go-Jek driver in the village of tongue Kulon. This research uses a quantitative approach. The population of this study is Go-Jek drivers who are active as a whole in the village of tongue Kulon which amounted to 35 people and a sample of 26 respondents. The results of this study found that the physical workload using the percentage of Cardiovascular Load (CVL) showed that Go-Jek drivers have a physical workload with an average of %CVL of 31%. Then the results of the SWAT method for Go-Jek drivers obtained values in the Effort dimension of 23.69%, then for Time of 64.43%, and for Stress of 11.89%. Then the most influential is the Load Time with an average load value of 64.43%. This means that Gojek drivers significantly feel the burden of time is more dominant in affecting their work.]]>

<![CDATA[The joining of steel in ship construction was carried out through welding technology. One of the joining processes used two types of welded joints, namely butt and lap joints. This study identified the strength of the test material from ASTM A36 steel plates at welded joints by standardizing the tensile test. Experimental activities using a tensile testing machine and simulation activities using SolidWorks. The average tensile test values for butt and lap joints show yield strengths of 288.89 and 200 N/mm2, final strengths of 419.11 and 280 N/mm2, reduction of cross-sectional areas of 49.33 and 43.33%, strain 7% and 18.67%, modulus of elasticity 60.81 and 15 N/mm2. Tensile test simulations for butt and lap joints showed plastic deformation in the weld face, root, toe, and HAZ area. Experimental and simulated difference values for butt joints range from 941.67 to 1,519.67 N/m2, and lap joints range from 1,030 to 4,694 N/m2. The final results show that SMAW welding with the butt joint type has a higher strength value than the lap joint.]]>

<![CDATA[The conditions of vulnerability and potential security threats in the sea area of the southern part of Java Island and the level of ability of elements operating in the area are still inadequate both in quality and quantity. This thesis uses qualitative research methods. Some of the vulnerabilities that can occur include illegal fishing, smuggling, pollution at sea, illegal crossing, terrorism at sea, and people smuggling. These threats can endanger Indonesia's interests in many aspects such as defense and security, the economy, and territorial sovereignty. Therefore a plan is needed to conceptualize the installation of a coastal radar to improve security in the area. The IMSS (Integrated Maritime Surveillance System) radar, which is already operating in the Malacca Strait area as an empirical example, will develop the coastal radar concept in the southern region of Java Island. With the existence of a coastal radar in the area that functions as an early warning system, it is hoped that all forms of threats and violations can be anticipated very well. The addition of a security element in the sea area of the southern part of Java Island in the form of installing a coastal surveillance radar is very important to implement given that the level of capability of the security elements operating in the area is considered to be insufficient for security in the wider sea area.]]>

<![CDATA[Subcritical water hydrolysis of bagasse requires energy to convert lignocellulosic biomass into fermentation-ready sugars. Bagasse biomass has the potential to be used as raw material for the production of reducing sugar. This study evaluates the effectiveness of the hydrolysis process using an oven and autoclave through economic and energy analysis. The variables used were hydrolysis time of 20-60 minutes, oven temperature of 110-170°C, and autoclave temperature of 120-130°C. Reduced sugar concentration was obtained from analysis using the DNS (dinitro salicylic acid) method. The results of the analysis show that time and temperature have a significant effect on the yield of reducing sugar. The highest reduced sugar concentration from subcritical water hydrolysis using an oven was 27.4 g/L at 170°C operating conditions for 60 minutes with a total cost of Rp 351,744 and energy requirement of 480 W.h. In hydrolysis using an autoclave, it was obtained at 14.7 g/L at 125°C for 40 minutes with a total cost of IDR 923,079 and energy requirements of 1,936.67. Hydrolysis using an oven is more recommended than autoclaving because it is economical and has lower energy consumption.]]>
