Comparative Study of Internal Force between Dynamic Method and Equivalent Static Methods in Lecture Buildings in Yogyakarta Based on Earthquake Indonesian National Standard (SNI 1726-2019)
Authors: Ernawati Enik , Widodo Slamet 
Published: August 2021

Abstract
Earthquakes are events of the movement of the earth due to the sudden release of energy in the earth which is marked by the breaking of the rock layers in the earth’s crust. Indonesia is located in an earthquake-prone area where three tectonic plates meet, namely the Indo-Australian plate, the Eurasian plate and the Pacific plate. Realizing the threat of an earthquake that could occur at any time, the Indonesian government took the initiative to take measures to prevent the risk of damage to infrastructure that could occur due to an earthquake. This paper presents an analysis of the earthquake resistance of a lecture building at an educational institution in the city of Yogyakarta with the equivalent static method and the dynamic response spectrum method. The purpose of this paper is to provide an overview of whether construction projects that have been implemented using SNI 1726-2012 are analyzed and compared with the latest standards, namely SNI 1726-2019, whether the building construction still meets earthquake resistance. The results of the comparative analysis of the equivalent static method and the dynamic response spectrum method show that the building under study does not meet the strength and resistance to earthquakes based on SNI 1726-2019, so it is necessary to strengthen the structure of the building under study.

Published: August 2021

Abstract
The old derrick steel truss structure had been found in imperfect structure such in some member loses and unsual bolt holes. The derrick structures were located in critical path room publics for instance the public transportation path and the electricity transmission networks. This research had a numerical model the single element linear buckling (eigenvalue) that were based on the finite element method. The derrick prototypes had been modeled in single element that had the largest axial compression load that was defined in the perfect model. The artificial circle holes were attached on the member then was defined in the imperfect model. The artificial circle hole as representative the unused bolt holes. The linear buckling analysis had been performed by utilizing the 3D frame and 3D solid idealization with the 6 buckling modes had been required. This research had also compared the single element buckling and the overall derrick structure buckling analysis. The results showed that the buckling capacity reduced due to the number of holes. The greates number had the lowest critical loads (Pcr) then had buckle early. The numerical buckling pattern had similarly with in the elastic buckling theory (Euler buckling) at every mode. The critical buckling stress was lower than the yielding stress for every models. The results also showed that the critical load of the single element was lower than the overall structure. However, considering the environmental load such in the seismic load then the overall derrick structure buckling failure had higher vulnerability than the single element buckling failure.

Authors: Veranita  , Tripoli Bambang 
Published: August 2021

Abstract
The quality of pavement is influenced by good quality materials. Alternative materials can be used to increase the adhesion and viscosity of asphalt, including the using of latex and waste materials. The using of waste materials from polyvinyl chloride (PVC) in addition to reducing environmental pollution problems is also expected to be an added material to improve the performance of asphalt. The purpose of this study is to determine the effect of using PVC on the asphalt mixture. The specification refers to the Bina Marga 2018 method, by making the specimen of three variations of PVC. The variations of PVC are 3%, 4% and 6%. The results of the Marshall test showed that the optimum asphalt content was 6.5%; 5.8% and 6%. The result of 30 minutes immersion Marshall test at 3% variation is 1,367.91 kg, at 4% variation is 1,283.84 kg and 6% variation are 1,225.81 kg. The durability value for three variation is 94.75%, 92.54% and 93.85%. The using of PVC as an additive indicated that the addition of PVC to the asphalt mixture can provide better durability but the higher the PVC as a additive can reduce stability because the void in mixture is low.

Authors: Andriani  , Yuliet Rina , Permana Dwiki 
Published: August 2021

Abstract
Road construction on clay causes many problems with road damage because clay has a low bearing capacity and a large swelling value. The soil stabilization method was used to improve clay soil characteristics by adding cement, lime, fly ash, or other stabilizing agents. One of the stabilizing agents used in this study is coconut shell charcoal. The purpose of this study was to analyze the effect of adding coconut shell charcoal to the CBR value and the swelling index on clay soil. In this study, the coconut shell charcoal used was 0%, 4%, 8%, 12%, and 16% of the dry weight of the soil. The samples used were disturbed soil, and the curing period was 7 days. Testing the physical and mechanical properties of the soil (CBR and Swelling test) refers to the ASTM Standard. The results showed that the addition of coconut shell charcoal by 4% increased the bearing capacity and reduced the swelling index. An optimal CBR value of 14.69% was obtained for the addition of coconut shell charcoal by 4% with the unsoaked condition with a 7-day curing period. Whereas in the soaked soil condition, the optimal CBR value is 8.53% and the swelling value is 0.24%. Increasing the CBR value and decreasing the swelling value will cause the road construction layer to be more stable in supporting the load.

Published: August 2021

AbstractThe purpose of this study is to assess the development of the municipal solid waste management in the City of Banjar, West Java Province. Municipal solid waste management in the City of Banjar has been developed as a system that is expected to implement the 3R concept of reduce, reuse, recycle. However, implementation of the 3R concept through solid waste sorting and composting as well as the service coverage are still very low. Effectiveness of the municipal solid waste management in the City of Banjar could be improved by gradually increasing solid waste sorting, organic waste composting, and the level of service. Improving solid waste sorting from 5% to 70% will produced recycled goods from 16 to 687 ton/month in 2030. Increasing the level of organic waste composting from 5% to 90% will increase the compost production from 35 to 1,905 ton/month, respectively. As a result, the volume of solid waste hauled to final disposal site which increases from 1,129 to 1,440 ton/month in 2026, will gradually decrease to 1,008 ton/month in 2030. It can be concluded that improving effectiveness will result sustainable solid waste management in the City of Banjar.

Authors: Li Xueling , Li Yichao , Li Renfu 
Published: August 2021

Abstract
Effective and efficient utilization of solar energy is highly demanded in the energy industry. Herein, based on the excellent optical properties of MXene, an MXene enhanced therminol®VP-1 nanofluid is proposed for direct absorption solar collector to efficiently absorb solar radiation. The nanofluid is experimentally prepared and characterized. Subsequently, the influence of mass fraction of MXene, collector height, and working temperature on the collecting efficiency of the nanofluid in DASCs is numerically investigated. The results show that even with a low mass loading such as 50 ppm, MXene enhanced therminol®VP-1 nanofluid still can effectively absorbs solar spectrum. The intercept efficiency of 50ppm nanofluid is 83.32%, which is higher by 20.48% than that of therminol®VP-1. The efficiency is strongly affected by collector height and MXene content and first increases and then decreases with increasing the mass loading of MXene. Moreover, the best content of MXene gradually decreases with the increase of the collector height. These findings suggest that MXene enhanced therminol®VP-1 nanofluid has promising prospects to achieve efficient solar photothermal conversion.
