Abstract

Mindfulness is a practice that is thousands of years old. This practice is also included in the modern mindfulness-based stress reduction training, and its effects on our cognitive system are supported by extensive literature that comprehend mostly fMRI studies and task-oriented experiments with control groups. In this paper, the problem of testing the effects of mindfulness therapy, with specific regard to the yoga practice, is addressed with a Network-Oriented Modelling approach. The first component of the proposed network simulates the elicitation of an extreme stressful emotion due to a strong stress-inducing event. This was done following the same line of previous papers that proposed simulations of similar processes. A second component represents the role of memory, attention, and self-awareness in coping with the stressful event. Finally, the yoga practice, divided into physical movements and breathing, is modelled, to show its influence on memory, attention, and self-awareness, leading in this way to a reduction of the stress level.

Abstract

Spatial archives in the form of analog maps still encountered in several work units, however, as times progressed, the quality of these maps decreased in terms of the materials used which could affect their accuracy. There are several techniques used in converting from analog to digital maps, including scanning technique, and a unification coordinate system with the rectification method. This study aimed to find out the horizontal accuracy and the accuracy class of rectified maps. The data used was an analog map of a map of the boundary demarcation of the Konak Forest area, Rejang Lebong Regency scale 1:1000. The analog map was produced more than 30 years ago. The steps carried out in this study were preparing data from scanning analog maps, setting coordinate systems, input GCP, control rectification, calculating RMSE and CE values, analyzing, digitizing, layout. The result of the rectification map shows the use of 4GCP produces the best value with RMSE 0.14m and CE90 0,20 and the horizontal accuracy is class 1 on a scale of 1:1000. 6GCP produces RMSE 0.5m and CE90 0.75 and the horizontal accuracy is class 3 on a scale of 1:2500. 10GCP produces RMSE 0.6m and CE90 0.95 and the horizontal accuracy is class 3 on a scale of 1:2500.

Abstract

This research is about coconut fiber material which has the potential to wall cover and the relationship between temperature and time of coconut fiber material in reducing temperature. The wall, as one of the building envelopes, endures high sun radiation. It needs the wall material that can reduce temperature to ensure thermal comfort inside the building. Gaining building thermal comfort requires architecture, knowledge, and skills as well as innovation. Lowering temperature in the room can be done through wall modifications so that it can lessen the use of air-con. Thus, research on the use of natural materials such as coconut fiber for walls is needed. This study is using an experimental approach. The coconut fiber was tested to measure the temperature reduction and study its linear equations from the relation between temperature and time given. The analysis is comparing two materials: (1) the mix of cement and sand without coconut fiber; (2) The mix of cement and coconut fiber material. The tests’ procedures are applying heat temperature to the side of the material and measuring the resulting absorbed temperature on the other side of both materials. Both of the material were exposed to 35°C heat temperature for 150 minutes. The materials are set in a box. The tests use 3 thermal sensors are T1, T2 and T3 and one heater. This heater is connected to the power source and a device to control the temperature given called Ts controller. The test shows different results between the temperature of material with coconut fiber and material without coconut fiber. The coconut fiber material has a lower temperature than that of without coconut fiber. The linear equation of the coconut fiber material related to the time and temperature shows the longer time, the lower the temperature is. Thus, it indicates the potential of coconut fiber material used as cover for building walls.

Abstract

Loading between phases must always be considered in order to reduce the imbalance, which results in an increase in neutral current and loss of conductor power. Non-linear loads can cause harmonics that affect the increase in copper losses in the transformer. Harmonics can cause distortion of the voltage and current waveforms, so attention must be paid to the specified limits so as not to interfere with the performance of electrical equipment. In addition, these parameters can affect the main electrical parameters, so they must be considered at the specified limits. This study aims to analyze the condition of load imbalance, harmonic content, and the effect on power loss in distribution transformers at Universitas Bangka Belitung. Parameters were measured using a Meterel Power Meter Analyzer type MI 2592 Power Q4 for ten days with the comparative method as a data analysis method. The average current unbalanced percentage is 9.91%, with the highest value at 24.31%. Energy due to power loss in the neutral conductor is 0.46 kWh/10 days, and the total conductor loss is 18.122 kWh/10 days.

Abstract

Bukittinggi City is a city in West Sumatra Province that is one of the popular tourist destinations for the public and tourists. The existence of tourist objects around the city center greatly affects the structure of urban space, in the use of space itself, it is very visible from the distribution of tourist facilities locations that spread around tourist objects that can attract hospitality and trade activities that spread to the downtown area in Bukittinggi. This study aims to determine how the spatial transformation of Bukittinggi City is based on tourism development from 1984 to 2021 and the factors that influence the development of the space. The method used in this research is qualitative. This study found that the City of Bukittinggi when viewed from the area of ​​development of the City of Bukittinggi reflects a concentric pattern, this can be seen from the location of the city of Ngarai Sianok which limits the development of the city to the west and north. Based on the performance agreement letter from the Public Works and Spatial Planning Office of Bukittinggi City in 2020, the percentage of suitability for spatial planning and utilization is 37.50%. The building mass in a developing tourist attraction has a heterogeneous textured area texture, where the shape of the mass and space configuration have different sizes, shapes, and densities. The high density of building mass only occurs in the core area of ​​the city with a percentage above 80%. The Bukittinggi City Regional Spatial Plan article 28 paragraph 2 explains that there are 5 types of road networks, namely primary arterial roads, secondary arteries, secondary collectors, local roads, and freeways. The road network in Bukittinggi City is growing rapidly towards the city center and in several residential areas. The distribution of tourist facilities is generally located in the city center and a small part is spread along Jalan Soekarno Hatta and Jalan Sudirman. The distribution of tourist objects has formed a concentric space in the city's core area with local and regional service scales.
