Published: April 2021

Abstract
Although monolayer WS2 (Tungsten Disulfide) has attracted many interest, controllable synthesis of large-area WS2 triangles is still challenging. Here, we report salt-assisted CVD growth of WS2 atomic layers using a kind of sandwich structure in a semi-sealed installation and firstly investigate the effect of the width of the hollow (Dss) of the structure. We demonstrated WS2 triangles growth up to 300 μm coverage and showed the effect of hollow on the crystal size. By optimizing the width of the domain, large-area WS2 films were obtained. We utilized optical microscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman spectroscopy and photoluminescence (PL). Our study provides method to fabricate large area WS2 flakes and the experiment is critical to building scalable devices.

Abstract
Cement has long been used as the main cementing material of the artesian paste filling material in the goaf of a mine, giving a generally high strength. However, the cement ‘two grinding and one burning’ process consumes a lot of energy, which aggravates the greenhouse effect. Therefore, a new type of cementitious material with lower energy consumption and lower emissions is needed. Solid wastes are useless by-products after mining and beneficiation, which are often dry piled in the open air, wasting land resources and polluting the environment. This project studied an alkali-activated mineral powder cementitious material, delineated its internal structure and morphology, and tested its mechanical properties. In a gelling system with 70% mineral powder, 30% Portland cement, 1% sodium silicate and a water-cement ratio of 0.4, the hydration reaction commenced the earliest and the early strength of the test block was the highest. In addition, further increasement in proportion of mineral powder or sodium silicate could not have a positive effect on the early strength of the system.

Abstract
One of the most curious phenomena observed in metal melts is the temperature-induced liquid-liquid structural changes. As a result of the thermal treatment lead to LLT, a more equilibrium and micro-uniform melt consisting of atomic associations is formed. In nickel alloy melts, the changes that have occurred are irreversible and have a significant effect on the formation of the final structure and the mechanical properties of the metal in the solid state after its crystallization. In addition, they are the starting point for the scientific substantiation of new technological modes of smelting and heat treatment of alloys, which further improve their operational properties, as well as reduce metallurgical defects and production waste, and rational use of expensive ligands. All this in general will lead to a significant increase in the performance of melts and metal products. Our work is devoted to the experimental confirmation of the LLT transition in two common nickel-based alloys by a non-invasive electromagnetic method.

Abstract
Cellular metabolites play a crucial role in promoting and regulating cellular activities, but it has been difficult to monitor these cellular metabolites in living cells and in real time. Over the past decades, iterative development and improvements of fluorescent probes have been made, resulting in the effective monitoring of metabolites. In this review, we highlight recent progress in the use of fluorescent probes for tracking some key metabolites, such as adenosine triphosphate, cyclic adenosine monophosphate, cyclic guanosine 5'-monophosphate, Nicotinamide adenine dinucleotide (NADH), reactive oxygen species, sugar, carbon monoxide, and nitric oxide for both whole cell and subcellular imaging.
Matrix Kesten recursion, inverse-Wishart ensemble and fermions in a Morse potential

Abstract
The random variable 1 + z
1 + z
1
z
2 + … appears in many contexts and was shown by Kesten to exhibit a heavy tail distribution. We consider natural extensions of this variable and its associated recursion to N × N matrices either real symmetric β = 1 or complex Hermitian β = 2. In the continuum limit of this recursion, we show that the matrix distribution converges to the inverse-Wishart ensemble of random matrices. The full dynamics is solved using a mapping to N fermions in a Morse potential, which are non-interacting for β = 2. At finite N the distribution of eigenvalues exhibits heavy tails, generalizing Kesten’s results in the scalar case. The density of fermions in this potential is studied for large N, and the power-law tail of the eigenvalue distribution is related to the properties of the so-called determinantal Bessel process which describes the hard edge universality of random matrices. For the discrete matrix recursion, using free probability in the large N limit, we obtain a self-consistent equation for the stationary distribution. The relation of our results to recent works of Rider and Valkó, Grabsch and Texier, as well as Ossipov, is discussed.

Published: April 2021

Abstract
Thermal comfort is a major factor for a building’s design, and is associated to room temperature conditions. Thermal comfort depends on climatic variables and several individual / subjective factors such as clothing, acclimatization, age, gender, level of health, and others. Measurements of thermal comfort made via Meteoblue and SunHour software at the Rifain Digital Printing location provide data including temperature, humidity, sun exposure and wind speed. The data is then synthesized using CBE Thermal Comfort, a software that detects conformity to thermal comfort standards in a room. The results of measurement and data synthesis indicated that the building requires a cooling temperature of 5.2 ° C. From these results, it can be said that the thermal comfort of Rifain Digital Printing is not optimal. Improvements are needed to the existing thermal conditions. One of the efforts to optimize thermal comfort is the use of vegetation and water (Talarosha, 2005). Based on synthesis result obtained through research and data processing through literature studies, we came up with a solution, namely a vertical garden with a water wall system design as an effort to overcome the problem of thermal comfort in the Rifain Digital Printing building.

Abstract
Operational energy contributes significantly to the most energy consumption of a building’s life cycle. Analysis of operational energy is usually conducted when a building is being operated. However, we can compare and predict the operational energy of a building’s designs to obtain the best design alternative low energy building. The objective of this study is to simulate the operational energy of the design of the Centre of Excellent (CoE) building at Universitas Pendidikan Indonesia (UPI). Rhinoceros and Grasshopper with Ladybug and Honeybee are selected as the software simulation due to the comprehensive features of energy simulation. This modern building will be constructed for five floors with an area of about 5000 m2 per level facing south and north sides. Analysis of operational energy calculated three main factors of cooling, lighting, and other equipment. The result shows that the annual operational energy contributes to about 586 kWh/m2 per year. This value is far from the basic standard for educational building, with about 240 kWh/m2 per year from ASEAN. The cooling system of the building is recorded as the highest amount of energy use. Further, evaluating the building’s operational devices and the strategy to reduce the energy loads will be proposed to accommodate a modern school building’s main issue that harms operating energy.

Abstract
Classroom is a place for a group of people to study and improve their knowledge. To make learning activities becomes more effective, a classroom is expected to have comfort in terms of thermal, lighting, ventilation, and acoustic. This study focused only on the acoustic comfort of the classrooms at Gedung Kuliah Bersama V (GB V), University of Bengkulu (UNIB). Acoustic condition in the classroom has a crucial role for student concentration that affect to student’s achievement. Reverberation time (RT), initial time delay gap (ITDG), and the possibility of echo phenomenon in the classroom will be identified in this study as the acoustic parameters. Ecotect v5.5 software is being used to simulate three types of a classroom that represent classroom types at GB V. This simulation is used to identify RT, ITDG, and echo occurs in the classroom. Results of this study showed that ITDG values of these three classrooms had met the standard the classroom that used for conversation, which is under 20 m/s. Echo phenomenon is also relatively not seen in the simulation. It means that these three classrooms were also comfortable enough in terms of acoustic. However, the RT values in the three rooms still have not reached the optimum condition, 1.40 m/s for RK 2.02, which is higher than standard and lower than standard for the first room and 0.23 m/s and 0.10 m/s for the second and third room. So thus, some design recommendations are needed to get an optimum RT value.

Abstract
Traveling is a right for everyone even though they have special needs, such as people with disabilities. However, until now there are still many facilities that are less accessible for persons with disabilities. Taman Bungkul as an alternative tourist spot in Surabaya must also provide friendly facilities for persons with disabilities. This paper aims to understand the tourism needs of persons with disabilities, to find out the availability of facilities and the efforts made by Taman Bungkul managers in providing facilities for visitors with disabilities. This research uses a qualitative approach. Qualitative data obtained from interviews, observations, and literature studies will be analyzed descriptively qualitatively. So that the research results can be input for stakeholders and tourism destination managers to increase the provision of friendly facilities for people with disabilities. The results showed that persons with disabilities have different definitions related to tourism activities. Taman Bungkul has provided several facilities for persons with disabilities, but it is not fully disability friendly because the conditions of the facilities are not up to standard and are still difficult for persons with disabilities to access. The management of Taman Bungkul continues to make efforts to complete facilities for persons with disabilities but is constrained by several obstacles, namely limited development funds and the absence of a Surabaya City government program that focuses on establishing tourist destinations for people with disabilities.

Spatial Zoning Analysis of Zoo in Urban Area as a Preliminary Assessment for Improving the Education and Recreation Roles
Authors: Dera R , Ridzqo I F 
Published: April 2021

Abstract
Zoos have an important role as an animal conservatory. An ex-situ animals conservation should have a living space that resembles its natural habitat while also functioning as an exhibition space for educational purposes. While in nature, animals require a large landscape as their habitat. Unfortunately, most zoos’ limited land areas impede them from doing so, especially for zoos in a dense urban area. As a form of public space in the city, zoos not only serve as an educational means for the urban community but also a recreational facility to withdraw from the urban life that is far from the natural environment. Several Indonesian zoos that occupied the minimum land areas in an urban context are Bandung Zoo, Surabaya Zoo, and Batu Secret Zoo. Unfortunately, the two first received relatively bad visitor reviews regarding the lack of animal exhibition space, entertainment space, and supporting space. Meanwhile, the more recently built Batu Secret Zoo, which shares a similar land area, continuously receives good visitor reviews because they feel it simultaneously meets their educational and recreational needs. Improvement is sorely needed for the other zoos. This paper analyzed the spatial zoning of the three zoos’ landscapes and associated them with the visitor experience. It is a preliminary step in assessing the zoo for further improvement in educational and recreational roles. The result shows that the animal exhibition zoning based on a specific design base plays a significant role in improving the educational and recreational function.
