Published: July 2020

Abstract

Jatropha curcas L. is a terminal flowering plant. The use of planting material from the beginning which has many branches (multi-entrenched seedlings) will certainly have the opportunity to provide higher yields, compared to single-stemmed seedlings. Three-month-old multi-entrenched seedlings (b1 = single-stemmed seedlings, b2 = seeds with two branches, b3 = seeds with three branches, and b4 = seeds with four branches) raised in polybags were planted in the field to evaluate the performance of these multi-entrenched seedlings in a Randomized Block Design with three replications, and each treatment consisted of five tree units. The result shows that the use of branched seedlings has a significant effect on the yield of Jatropha started in the first year of cultivation. Seedlings with two entrises were very well multi-entrenched seedlings used, offered seed yield about 408.2 g per tree in the first year, and 1,118.4 g in the second year of cultivation.

The Importance of Railroad Crossing Doors as Rules of Safety and Environmental Safety: An Overview of Responsibilities
Authors: Ratnawati Elfrida 
Published: July 2020

Abstract
Train accidents often occur on level crossings, due to the absence of a doorstop that restricts any vehicle passing through. This is due to the fact that in addition there is no security of the crossing doorstops, negligence of the railroad gate guard, and the attitude of the driver who is not disciplined. Who is responsible for the manufacture of railroad level crossing barriers for safety and security?, What is the responsibility of the Railroad in the event of an accident resulting from the absence of level crossings? and the research method used is Normative legal research, analyzed descriptively, using secondary data supported by primary data and processed qualitatively. The results of the study found that Article 94 of Law Number 23 Year 2007 concerning Railways states paragraph (1) For the safety of railroad trips and road users, level crossings that do not have a permit must be closed; Paragraph (2) Closure of level crossing as referred to in paragraph (1) shall be carried out by the Government or Regional Government. If an accident occurs due to the unavailability of a crossing doorstops, then PT. Kereta Api Indonesia is not responsible for the accident, because the responsibility for procuring the level crossing is not the responsibility of PT. Kereta Api Indonesia.

AbstractLubrication systems on ships are vital for a ship to operate while sailing. Lubrication serves to prevent direct friction between components on the ship engine, especially the gearbox. Gearbox is one of the components of the ship crane that acts as the propeller of the ship. Obviously related to friction between components, therefore a lubrication system is needed. Some lubrication systems on Indonesian warships still use manual systems to monitor oil and filter change schedules. This can make the operator forget about the oil and filter change schedule. With the development of technology that is now the author makes a prototype with an oil and filter feasibility detection system on a ship gearbox. The author uses the SVM method that is able to classify properly or not like an oil. By using a viscosity sensor and a temperature sensor to be processed by the SVM method and a color sensor to detect a color in the oil filter. The results of the SVM method are quite accurate with 100% accuracy can distinguish good and bad oil from the samples used are new oil and used oil. There is a change in the intensity of the light that causes the color sensor readings in conditions of 100%, conditions of 30%, conditions of 40%, and conditions of 50%.

Abstract
With the rapid development of the urbanization in China, the wetland ecotourism has become a popular form of travelling for the most of consumers in recent years. The development of the wetland ecotourism not only can enrich the ways of tourism and promote the economic development of the wetland areas, but also can establish a foundation for the comprehensive development of tourism industry. However, as the development of tourism industry in China is not long enough, at present, the wetland ecotourism is still making process. Besides that, due to the lack of scientific understanding, people often ignore the influence and destruction of the tourism ecological resources caused by travelling. And people also ignore the psychological capacity and economic demand of the residents who live in the wetland. This paper intends to carry out a field study on Xixi Wetland to explore the existing problems of the ecotourism on it. And then, according to the result of this research, the corresponding countermeasures of ecotourism are provided based on the analysis of the sustainable development of ecotourism of Xixi Wetland.

Published: July 2020

Abstract
The combination of aquatic vegetation restoration and biological manipulation had become one of the important ways of ecological restoration of lake water. Zooplankton was closely related to aquatic plants, which affected the species composition, density and diversity index of zooplankton. Zooplankton was also a part of biological manipulation, which helped to control phytoplankton and improved the transparency of water body. Through the analysis of the role of zooplankton in ecological restoration and the response of zooplankton to the ecological restoration of water body fully reflected the complementary relationship between biological manipulation and aquatic vegetation restoration. Combined with the practice of zooplankton changes in the ecological restoration of typical tropical shallow city lake, it was expected to provide basis and support for the restoration of urban lake.

Abstract
The safety of foundation pit is related to the safety of surrounding buildings and roads, so it is necessary to closely observe the settlement around the excavation process. Based on the monitoring data during the excavation of the deep foundation pit project in a hospital in Guiyang, this paper studies the variation law of the excavation process of the deep foundation pit:If the excavation depth of the foundation pit is above 9 m, the key factor affecting the settlement is the surrounding shallow foundation, and the factor that has great influence on the settlement of the foundation pit below 9 m is the side length of the foundation pit;After the depth of the foundation pit reaches 15 m, the influence of the side length of the surrounding shallow foundation and the foundation pit on the settlement around the foundation pit will gradually disappear, and the settlement of the foundation pit will become stable at this time;Around the road settlement in the excavation depth of 12 m more obvious changes in the settlement area below 12 stable and less later changes;The change law of crown beam settlement and horizontal displacement of foundation pit tends to be consistent with the surrounding settlement.

Authors: Wang Zhaofeng 
Published: July 2020

Abstract
In this study, in order to solve the limitation of the modified Mohr-Coulomb criterion in the numerical implementation induced by the corners or apexes, a modified Mohr-Coulomb criterion with smooth tension cut-off has been proposed. Both the nonlinear meridian shape function and the deviatoric shape function have been studied, and the failure surface of the proposed criterion is smooth and derivable at any stress states. The criterion has been verified through numerical simulations and comparison with the experimental results. Furthermore, it will be easier to adopt this smooth criterion in the numerical algorithm without losing good qualities of modified Mohr-Coulomb criterion.

Abstract
Based on the investigation data of Jiaozhou Bay in 1992, the vertical distribution and seasonal variation of Hg in the surface and bottom layers from the center of the bay to the southeast of the bay were studied, and the seasonal distribution, variation range and horizontal distribution trend of Hg content in the surface and bottom layers were determined. The results showed that in May, August and October, in Jiaozhou Bay, from the central water area to the coastal water area in the southeast of the Bay, from the surface layer to the bottom layer, the range of Hg content in the bottom layer and the surface layer was: 0.007-0.040 μg/L, which conformed to the national water quality standard of class I seawater, and the water was not polluted by any Hg content. From May to October, in the central waters of Jiaozhou Bay, the seasonal changes of Hg content in the surface layer from low to high were spring, summer and autumn, and the seasonal changes of Hg content in the bottom layer from low to high were autumn, spring and summer. In the surface of the coastal waters in the southeast of Jiaozhou Bay, the seasonal changes of Hg content in the surface and bottom layers from low to high were autumn, spring and summer. The author put forward the law of Hg deposition: in summer, marine organisms propagated in large numbers, but in spring and autumn, there was no large number of marine organisms propagated. In this way, the Hg content sediment depended entirely on the combination of zooplankton, phytoplankton and floating particles in the sea water. Therefore, in summer, a large amount of Hg was taken to the seabed, while in spring and autumn, no large amount of Hg was taken to the seabed. In May, August and October, the change of Hg content in the surface and bottom layers fully confirmed the settlement law. Moreover, it was believed that a large number of marine organisms in the water were the main carriers to bring a large number of Hg to the seabed. Therefore, the variation of Hg content in the bottom was determined by the surface Hg content and the vehicles that transport Hg content vertically to the sea bottom, which resulted in the fact that the horizontal distribution trend of Hg content in the surface and bottom was same.

Published: July 2020

Abstract
High strength steel structure is more and more widely used in the field of building structure because of its advantages in mechanical properties. The design of high-strength steel frame often refers to steel structure. For the high-strength steel with no yield platform of stress-strain curve, the influence of plastic strain before the nominal yield strength of its material on the results of the frame remains to be studied. In order to study the influence of plastic effect on high-strength steel frame, the second-order elastic-plastic analysis of typical frame is carried out and compared with the simplified design method of steel structure design standard. The results show that the plastic effect has no significant effect on the bending moment and lateral displacement of high-strength steel frame in most cases. Base on the analysis results, the design suggestions of high-strength steel frame structure are put forward.
