Seismic design methods for concentrically braced frames
Authors: Marcu R , Köber H
Published: May 2021

The present paper is intended to point out the main differences existing among the seismic design procedures for concentrically braced frames contained in different seismic design codes. Two ten storeyed concentrically braced frames were designed taking into consideration the provisions of three seismic design codes: the Romanian norm P100-1/2013 [1], the European standard EN 1998-1:2004 [2] (respectively SR EN 1998-1:2005 [3]) and the American code AISC 341-16 [4]. All structural members of the concentrically braced frames (braces, beams and columns) had built up I-shaped cross-sections, sized according to the provisions of SR EN 1993-1-1:2006 [5]. Each designed frame was subjected to static nonlinear analyses. The seismic design loading state in different kind of structural members and the estimated steel consumption, the maximum values of base shear forces and horizontal floor displacements were compared. The successive formation of plastic hinges and the plastic failure mechanism in the different designed frames was analysed. A configuration with additional potentially plastic zones along the frame girders was proposed in order to improve the behaviour of the concentrically braced frames during static and dynamic nonlinear analyses.

Authors: Şuică Marian , Năstase Ilinca
Published: May 2021

Despite the latest global developments (new materials and less polluting technologies) and in spite of the treaties signed at world level (the Kyoto Protocol 1997 and the Doha-2012 amendment, the Paris Treaty 2015) regarding global climate change, the implementation of these measures to reduce pollution, protect the environment and strictly respect them, leave it to be desired. Climate change caused by global pollution, in large industrial regions and in major cities of the world, has led to and continues to lead to a decline in the air quality we breathe in Europe and in the world. The degree of urban and industrial agglomeration of the cities, contributes significantly to the increase of local pollution by mixing all the pollutants present in the air, this mixture of pollutants is favoured by street canyons and implicitly by the significantly lower dispersion of pollutants in atmosphere. Monitoring air quality in the urban environment and measuring as accurately as possible the concentrations of air pollutants, through the presence of as many sensors and monitoring stations in the monitored area as possible, as well as the implementation of analysis and interpretation hardware and software solutions of the data gathered in real time by these monitoring stations, is very important for the future of large urban agglomerations.

Published: May 2021

In this article the effects of different airflow rates introduced by the ventilation system are investigating by numerical simulation over the thermal comfort of the driver in a regular vehicle. The 3D LDV (Laser Doppler Velocimetry) measurement for the diffusers velocity field was imposed as boundary condition at the inlets of the investigated domain. Also, the flow rate discharged by each diffuser was measured for the first three positions of the air conditioning system. In the numerical model which was previously validated we imposed the boundary conditions from the experimental sessions. Thermal comfort was assessed by calculation of the equivalent temperature on the surface of a virtual manikin on the driver place and by the determination of the maps of Predicted Mean Vote (PMV) and the Draft rate indices. A first conclusion is that the results of the three flowrates may assure the comfort of the front passengers and a draft sensations and uncomfortable state for the rear passengers.

Authors: Setiawan O , Nandini R
Published: May 2021

Sub-watershed prioritization based on erosion propensity plays essential roles in decision making in implementing management practices, especially in the sensitive semiarid regions. Geomorphometric and landuse/landcover datasets are crucial in terms of sub-watershed prioritization for integrated watershed management. Our study was held in Sari Watershed, Sumbawa Island, which needs to be given proper consideration of prioritizing sub-watersheds that need immediate handling. Integration of Principal Component Analysis (PCA) and Weighted Sum Approach (WSA) was used to determine the final sub-watershed prioritization. The use of PCA aimed to define significant parameters, while WSA was employed to determine the weights for significant parameters and calculate the compound values for priority ranking. The result showed that the integration of PCA and WSA was robust enough to define significant and more effective parameters with their weighted values for the sub-watershed prioritization. The adopted methodology in this study can be applied to different susceptibility in sub-watershed prioritization, such as a flash flood. This study also provides essential information for watershed managers to prioritize the program’s implementation in the prioritized sub-watershed.

An interesting issue arises to be raised in scientific publications, namely what is the meaning of the nglungsur ritual to release the spirit for the Seblang traditional ritual practitioners? In analyzing the problem, hermeneutic theory is used. The problem of applying hermeneutics is divided in two ways: a distinction is made between the substance of intelligence (understanding) and sustiliasexplicandi (application). Hermeneutic’s task is to adapt the meaning of a text to the concrete situations in which it speaks. Gadamer formulated two forms of understanding, namely understanding the truth content (Turtth content) and understanding the intention (intention). Understanding of the content understands the meaning contained in the proposition and the substance of the text material. Understanding the intention means understanding the conditions or situations behind the phenomenon or text. It is this understanding of this second aspect that later became Gadamer’s attention as an awareness of historical understanding. The research method used, namely observation, interviews, documentation. With the hope of understanding directly themeaning of the nglungsur ritual in the life of the Using people.

The HOTS (Higher-order thinking skill) is significantly important, especially in the twenty century. One of the indicators of HOTS is metacognition skill. This skill is related to how students can understand and control their learning styles and mechanisms. However, encouraging the rise of students’ metacognition skills is considered to be a challenging task for a teacher. Therefore, this research aims to develop the students’ metacognition skills under the implementation ofthe RBL (Research-Based Learning) model of teaching in solving division problems. This research uses a mixed-method combining a quantitative and qualitative approach in mathematics. The research subjects consisted of a control class of 28 students and an experimental class of 28 students. Data collection techniques utilizedtests, questionnaires, observation, and last interviews. The results show that after the implementation of the RBL model of learning, the percentage of students metacognition skills of the control class is classified as follows: very well developed is 7% of the number of students, well developed is 48%, developed 38%, fairly developedis 7 %, poorly developed is 0 % and very poorly developed is 0%. The experimental class gaining very well developed is 33 % of the number of students, well developed is 55%, developed is 10%, fairly developed is 2%, poorly developed is 0% and very poorly developed is 0%. The statistical analysis of the two classes indicates that the inferential t-test shows that the GIS (2-tailed) value is 0.000 (P ≤ 0.05). It implies there is a significant effect of RBL application on the students’ metacognition skills. Students under RBL implementation showed their metacognition skills higher than the students without RBLin solving division problems.

As it is known, the continent of Australia was once occupied by Britain, which was originally a place for the laying of prisoners because at that time the prisons in England were full. Aboriginal is the name for the indigenous people who inhabited Australia for the first time. Aboriginal is the name of a tribe that was given by accident by the Europeans who saw it for the first time in Australia and this name applies to the designation of indigenous Australians to this day. The name of the Aboriginal tribe is a gift from Europeans who visited Australia and were surprised to see that the continent was inhabited. The term “Abo” means an astonishment of European society, and “origin” means authentic. The origin of the Aboriginal people is believed to have come from Asia who later occupied Australia for 45,000-50,000 years. The description of Aboriginal people is almost the same as the physical characteristics of the Papuans, the Toala people in Sulawesi, the Sakai people in Malaysia, the Veddas people in Sri Lanka, and the indigenous tribes of South India (Siboro, 1989). Aboriginal life before the arrival of Europe was rough and still very primitive. The way of life that is one with nature as well as various Aboriginal traditions and cultures is very interesting because it takes full advantage of the existing natural systems. For this reason, the study of Aboriginal people is very interesting.

Climate change has been causing severe damage in Kalimantan, such as forest fires in the dry season and flooding in the monsoon rain has been understood. Both of these results in loss of social-economic properties and environmental assets, and possible to create a climate emergence, especially in wetlands. The research about how the local people use traditional ways to revive their food and income through Permaculture garden in wetland has been conducted from 2018 – 2020. This research aims to elucidate the local people capability in use their local wisdom, traditional knowledge and ecological attitude on providing food in the transition of the wetland environment, through implementation of Permaculture concepts, learning and interaction.. About sixty voluntary respondents involve in forum group discussion, deep interview, and Permaculture gardening. The result shows that informal and local unique interaction among the local in implementing traditional, ecological knowledge and attitude in Permaculture gardening able to produce vegetables and fruits for daily, monthly and annual income. Thus, the observation of the implementation and the interaction on the concept of Permacultures may be possible to ensure us about the local sustainable food provision.

Land fires have become a new phenomenon in Indonesia that has occurred continuously every year and on a large scale since 2010. Land fires mostly occur on peatlands during the dry season and the focus of this research is to find the solution for fire problem in peatlands. In this case, a hydrological approach is carried out to explain the causes of the fires that occur, and a solution is also made using this scientific approach. Many peatland fires occured when the groundwater level on the peat reaches 0.4 m below the surface of the land. Then a water balance analysis was carried out to calculate the potential for water in peatlands and also the water needed for evapotranspiration and other needs. After obtaining the amount of water demand, a long storage design with a volume of 1,097,344 m 3 was planned which was divided into six reservoirs. Long storage was designed with a transverse length of 35 m in the canals and with runners that have a height of 4 m from the riverbed. With storage in long storage, it was hoped that the existing water can be used in an effort to rewet peatlands and prevent potential fires.

Referring to Ministerial Regulation No. 12 of 2017 concerning to Complete Systematic Land Registration program and the latest Presidential Instruction No. 2 of 2018 about concerning the Acceleration of Complete Systematic Land Registration with the aim of completing the registration of 79 million land fields that do not yet have guaranteed ownership of land rights. Then this study aims to know about how public services performed by Sungai Ulin Sub District Office for Complete Systematic Land Registration program by using a descriptive qualitative approach. Searching for data by direct observation in the field, this research is more directed towards services in completing the measurement of land field by referring to Zeithaml’s theory of 5 dimensions of indicators in assessing service quality, namely 1. Tangible (physical) in the form of convenience of service places, the ease of service processes, discipline of officers, the use of service aids, and the appearance of the officer. 2. Reliability in the form of accuracy of officers, clear services, and expertise of officers. 3. Responsiveness (response) in the form of responsiveness, accuracy, accuracy, and response to complaints. 4. Assurance in the form of guarantees on time, guarantee costs, and guarantees legality. And the last 5. Empathy, which is to prioritize customer interests, friendliness, and non-discrimination.

Environmental Literacy is considered as one of the few perspectives necessary for SDGs to be achieved. At the same time, the concept of environmental literacy is often discussed with the concept of scientific literacy as basic requirement of environmental literacy. Scientific literacy is defined as the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity. This study investigated the correlation between students’ environmental literacy and students’ scientific literacy after their scientific literacy has been improved using wetlands-based STEM educational approach. The results shows’ that there is no significant correlation between students’ scientific literacy and environmental literacy (ρ =0.085; sig.=0,519; α=0,05). This study discusses how environmental literacy should be a joint effort between educators from all different fields for it to be cultivated within student’s life.

Wild honey bee and Sumbawa horse milk is the local product from West Nusa Tenggara, Indonesia, which has the characteristic of little sour in taste. The sour taste indicates lactic acid bacteria (LAB) existence that has a potential function as probiotics. The objection of this study is analysis of lactic acid bacteria biodiversity from wild honey bee and Sumbawa horse milk by using Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR). The genome of cultured samples from M17 and MRS medium were extracted, then identified by RAPD-PCR with primer (GTG)5 (5-GTGGTGGTGGTGGTG-3). The scoring of DNA fragments was analyzed using the Numerical Taxonomy and Multivariate Analysis System (NTSYS) application. The result show five clusters from a common ancestor indicated the broad diversity of LAB in wild honey bee and Sumbawa horse milk.

Local people in Sumatra have long utilized herpetofauna to provide food, medicine, and other purposes. However, research related to wildlife utilization is still lacking. The objective of this paper was to provide an overview of the island-wide (i.e. Sumatra) traditional use of herpetofauna by the local people and analyze its implications for conservation. Published papers were collected and analyzed. From 11 papers, 22 wild-caught species (18 reptiles, 4 amphibians) were used by local people for their meat (water monitor, freshwater turtles, large-sized snakes), eggs (marine and freshwater turtles), or medicinal purposes (snakes, lizards, frogs; as skin-related remedies). Among them, 8 reptiles are listed in the IUCN Red List and CITES Appendices, including Batagur borneoensis (CR, Appendix II), Chelonia mydas (EN, Appendix I), Notochelys platynota (VU, Appendix II), Ophiophagus hannah (VU, Appendix II), Ortilia borneensis (EN, Appendix II). Additionally, 5 reptiles are protected by Indonesian law. Batagur borneoensis is also listed as a very high priority species for conservation by the Ministry of Environment and Forestry. No amphibian is protected by law, listed in the CITES, nor IUCN Red List. Traditional uses of protected species and listed under the IUCN Red List need to be managed properly to ensure their sustainability.
