Published: December 2021

Abstract
With the rapid development of the Internet of Things and wearable electronic devices, China is about to enter the 5G era. The current materials have been difficult to meet the production needs of flexible antennas working in the 5G frequency band. Flexible antenna sensors have received widespread attention because they can detect signal changes caused by antenna deformation. In recent years, miniaturization and high sensitivity have been the development trend of flexible antennas. However, traditional metal materials have disadvantages such as high density, easy corrosion, and poor bending stability, Can no longer meet the further development of 5G frequency band flexible antennas. Therefore, it is necessary to find a light and flexible material to replace the traditional metal material. Graphene has excellent flexibility, conductivity, and stability, once discovered, it has aroused widespread concern among scientists. This article mainly conducts certain research on graphene material, hoping to contribute to the development of 5G in China.

Abstract
The fusion power produced in a DT thermonuclear reactor is currently determined by measuring the absolute 14 MeV neutron yield of the D(T, α)n fusion reaction. Measurements of 17 MeV gamma rays born from the much less probable D(T, 5He)γ reaction (branching ratio of ∼10−5) have been proposed as an alternative independent method to validate the neutron counting method and also to fulfill the requests of the nuclear regulator for licensing ITER DT operations. However, the development of absolute 17 MeV gamma ray emission measurements entails a number of requirements, such as: (i) knowledge of the 17 MeV gamma ray to 14 MeV neutron emission branching ratio; (ii) the simulation of the gamma ray transport from the extended plasma source to the gamma ray detectors; (iii) a careful determination of the absolute efficiency of previously calibrated gamma ray spectrometers. In this work, we have studied the possibility to infer the global gamma ray emission rate from measurements made with a 3″ × 6″ LaBr3 spectrometer installed at the end of a collimated tangential line of sight at the JET tokamak and using the neutron emission from deuterium plasmas of the most recent experimental campaigns. Results show that 17 MeV gamma ray fluxes at the end of this tangential line of sight have a weak dependence (less than 5%) on the plasma profile and can therefore be used to infer the total emission from the plasma.

Abstract
This brief communication presents our work to determine the
absolute light yield and quantum efficiency of LaBr3:Ce
scintillator by comparison and also by direct pulse measurement
method using SiPM. The first part presents use of the simpler
comparison method to determine the light yields of different
scintillators using the known yield of NaI(Tl) as reference. In the
second part we have determined the absolute light yield and quantum
efficiency of LaBr3:Ce crystal by using a SiPM photo
detector. Our measured value is in good agreement with the light
yield reported by previous measurements using PMT and excitation
fluorescence spectroscopy. Quantum efficiencies for scintillation
detectors have been determined by using both PMTs and photo
detectors, namely APDs by previous authors. This communication is
possibly the first report on the determination of quantum efficiency
of LaBr3:Ce using SiPM photo detector. The simple and effective
method presented here would allow to determine the light yield of
any scintillation detector.

Published: December 2021

Abstract
Concrete curing is an effort made to optimize the results of concrete casting. This action needs to be done because it has a major effect on the quality and strength of the concrete, one of which is so that the concrete does not lose moisture too quickly, because later this condition will lead to excessive shrinkage in the concrete. As a result, the concrete can experience cracks. This will cause the construction work to be less qualified and endanger construction users. The purpose of this study is to determine the effect of concrete treatment methods on the value of normal concrete compressive strength. Concrete curing can be carried out by several methods according to the type and condition of the structural elements to be treated. From the results of the study, it was found that the curing method of concrete had an effect on the value of normal concrete compressive strength, namely that the average compressive strength value in the fresh water immersion treatment method was 23.730 MPa, the treatment method for wrapping concrete with gunny sacks was 22.349 MPa, the treatment method of wrapping concrete with plastic is 22.306 MPa, and in the treatment method of pouring concrete with fresh water is 21.199 MPa. The average value of the maximum compressive strength occurred in the treatment method with fresh water immersion, namely 23.73 MPa, and the minimum compressive strength value that occurred was found in the treatment method with fresh water sprinkling, namely 21.199 MPa. Thus, that concrete curing is good, namely, by soaking the concrete with fresh water.

Published: December 2021

Abstract
The length of reinforced concrete blocks varies widely, while in general the reinforcement produced in Indonesia is 12 m. Therefore, the use of reinforcement in a long stretch is done to be connected. The through connection is the most economical connection [2]. Lap splice can be made by overlapping the reinforcement which is touching or separate [3]. Splicing reinforcement can cause the strength of reinforced concrete beams to be reduced or even damaged so that rehabilitation measures are needed which can be in the form of retrofit (repair). Retrofitting with wiremesh and self compacting concrete (SCC) is considered to improve building structures. Reinforcement overlapping on reinforced concrete beams retrofit with wiremesh and self compacting concrete can be analyzed by numerical methods to determine their effect on bending behavior. Now, to analyze a structural behavior, it can be done using finite element method based program. The application of the finite element method is used in several programs, including ABAQUS, ADINA, Atena, ANSYS, etc. This study aims to analyze the overlapping of reinforcement in retrofit reinforced concrete beams against the flexural behavior, overlapping is made at one-third and one-third of the beam span using finite element method based analysis software.

Abstract
Inundation due to heavy rain often disturbs traffic flow and porous pavement as a wearing course is one solution to overcome standing water. This asphalt mixture uses an open gradation which is dominated by coarse aggregate with an air cavity content ranging from 20% - 25%. In Indonesia, according to the Indonesian Solid Waste Association (2013), this type of plastic waste ranks second with 5.4 million tons per year and is ranked second in the world as a producer of marine plastic waste after China. This research tries to use plastic waste as an added material in the porous asphalt mixture where the gradation of porous asphalt refers to REAM Specifications, 2008. The type of plastic used is Low Density Polyethilene (LDPE). The levels of plastic waste used were 0%, 2%, 4%, 6%, 8% of the total weight of the mixture. Marshall and Cantabro characteristics tests were conducted to evaluate the resulting mixture. The results of this study indicate that the stability value meets the REAM specifications, namely 350 - 800 kg. Marshall test results with the use of LDPE plastic waste as an additive to the test object meet the characteristics of Marshall except for Marshall Quotient (MQ) and voids filled with bitumen (VFB).

Published: December 2021

Abstract
The East Motoling area is one of the prospect areas in the Minahasa region of North Sulawesi, which has indications of low sulfidation epithermal-type mineralization. The research was conducted as a preliminary study to determine the characteristics of geological conditions, alteration, and ore mineralization in the epithermal system. The research method is divided into two main parts, such as fieldwork including surface geological mapping (lithology, stratigraphy, geomorphology, structural geology, alteration and mineralization) and laboratory analysis methods including petrographic analysis. The stratigraphy of the study area consists of altered volcaniclastic breccia, altered lapilli tuff, altered tuff, limestone, welded lapilli tuff, and andesitic breccia. Volcaniclastic breccia, altered lapilli tuff, and altered tuff, member of the Volcanic Rock Formation which is Late – Middle Miocene age, are the host rock for ore mineralization and hydrotermal alteration process. There are 3 types of alterations that have developed, namely argillic (illite + quartz ± kaolinite), sericitic (sericite + illite ± chlorite), and propylitic (chlorite + epidote ± illite). The dextral slip fault with NW – SE trend present as a main control structure to formation of extention fracture/vein. The epithermal veins are relatively north-northeast – south-southwest, north-northwest – south-southeast, and northwest – southeast. The textures of the veins divided into 7 main groups, namely that is bladed-quartz, breccia, calcedony, colloform, comb, mold, and massive quartz. Ore mineralization is forms in the veins as pyrite and banded sulfide. Apart from that, the disseminated pyrite also limitedly found around the veins.

Published: December 2021

Abstract
Mulberry (Morus nigra L) is a dicotyledonous plant in the family Moraceae which often used for silkworms’ breeding. Mulberry propagation still uses conventional technology, such as cuttings and graftings. The problem of mulberry propagation is the low productivity of mulberry gardens. However, tissue culture is a technique of isolating plant parts in the form of organs, cell tissues, and protoplasms that is effective and efficient in order to get uniform and superior plants in a short amount of time. For mulberry growth, the right combination of the Plant Growth Regulator (PGR) in the form of Kinetin, IAA, IBA is needed. Data were analyzed using R-statistic software. The results showed that M6 media (MS + Kinetin 1.5 + 1 IAA) was the best combination of media for the number of shoots, leaf length, and number of roots, with 80% of live explant percentage. Propagation via tissue culture such as clonal propagation, organogenesis, and somatic embryogenesis in callus cultures followed by generation of shoots/plantlets represents a potential effective propagation method in the future.

Achieving Sustainable Development Goals (SDGs) through indigenous group protection in Indonesia
Authors: Ramli R , Wahyudin  
Published: December 2021

Abstract
The 2030 Agenda for Sustainable Development Goals SDGs with its universal, integration, and inclusivity principles, is a commitment to promote sustainable development in accordance with human rights and equality to encourage social, economic, and environmental development and ensuring that “no-one left behind”. SDGs also promotes six pivotal elements: planet, people, dignity, prosperity, justice, and partnership. This research examines that since Indonesia has committed to reach and implement SDGs into the National Medium-Term Development Plan, the number of environmental and human rights issues has increased. In particular, the issues of the arrest of indigenous groups that try to protect their lands from land clearing for palm oil companies or infrastructure development that build their business by destroying the natures or homes of the indigenous groups. The issues are closely related to Goal 5, 10, 11, and 13-16. This shows the inconsistency of the Indonesian government in implementing the SDGs. Thus, this paper argues that to reach the goals, the Indonesian government has to acknowledge indigenous groups that play pivotal roles in preserving the environment, through local regulation

Published: December 2021

Abstract
Composite Cement (ECC) addresses a special type of high performance fiber reinforced composite cement with high tensile ductility. Fibers have been used to increase the toughness of quasi-brittle cement-based materials. As a result of its ability to produce high tensile ductility, ECC originally designed its strain-hardening behavior using a micromechanical concept, so that over-tensile strain capacity could be achieved in excess of 2% through multiple cracks. This research method is carried out by means of laboratory testing in accordance with data from literature studies both Indonesian SK SNI Standards and foreign standards, namely ASTM. The method applied in this research is an experimental method. The independent variable in this study is the reinforcement with the addition of fiber to the PVA ECC material mix, while the dependent variable in this study is the compressive strength value and the magnitude of the elastic modulus of the PVA ECC material. The results of the tensile strength of the ECC PVA material obtained on average at the age of 7, 14 and 28 days were 3.108 MPa, 3.547 MPa and 4.34 MPa, respectively. The tensile strength of the ECC PVA material increases with age. The average modulus of elasticity of PVA ECC material obtained at the age of 7, 14 and 28 days was 18763.02 MPa, 20788.81 MPa and 21060.03 MPa, respectively. Based on the modulus of elasticity, it also increases with the increase in compressive strength.

Abstract
The purpose of this study is to analyze the effect of proactive and reactive performance on indicators of the application of OHS in high-rise building construction. The data used in this study were obtained from a questionnaire (primary) and several observations and direct interviews with employees in 20 types of high-rise building projects in Indonesia. The analysis technique used is multiple regression analysis using hypothesis testing, namely the F test and t test. The results showed that simultaneously and partially the independent variables consisting of proactive performance (X1) and reactive performance (X2) had a significant effect on the variable construction K3 program (Y). From the ANOVA or F test, a significant number (Sig) (0.037) is obtained which is below 0.05 and the Fcount is 11.570 where the F count is greater than F table, F table is 3.84. These results indicate that the regression model is feasible to be used to predict the proactive performance and reactive performance variables together to influence the performance of the OHS culture of high-rise building construction. Seeing the performance points of construction project employees can be influenced by many other points from the results of the T Test calculation where the competence of workers obtains T results of 3.098 or the highest among others so that with this we can say that worker competence is a critical factor in improving cultural performance.
