Published: December 2024

Abstract
Tourism learning as a form of education currently still uses conventional methods, such as using books as learning media. This method has an impact on the large number of papers needs to print into the books so that all students have them and learning by the book. The usage of this papers, that we know comes from trees, can be reduced, by using Augmented Reality (AR) Technology. In addition, with AR we can include learning materials according to the curriculum into the AR application. This paper proposed the design model of AR prototype that can be used as a learning medium with tourism objects. The use of the proposed AR model aimed to enhancing user education in tourism education, learning literacy, numeracy, and psycholiteracy, while promoting environmental sustainability by reducing paper usage. The proposed model has several steps, such as developing the AR Eduwisata application, disseminating the app for the user, namely elementary school students, so becomes a learning stimulus for students and produces learning responses, and has an impact on student habits in each of their learning activities. We also proposed a software development model namely prototyping model. Future research will focus on implementing AR, expanding the 3D object tourism, and performing evaluations to various users in elementary schools in Bangka Belitung.

Published: December 2024

Abstract
The Granite rock covered almost one-fifth of the land on Bangka Island. The construction of settlements and various infrastructures on granite formations has increased. This research intended to analyze the parameters controlling the granite quality (S-type and I-type), which are widespread on Bangka Island. The Rock Mass Rating (RMR) and Geological Strength Index (GSI) methods measure the rock quality and their controlling factors. As a result, granite has RMR and GSI variation quality from fair to very good. Granite at the coastline tends to be of lower quality than those further from the coastline. Geological structure and weathering are the main factors causing a decreasing rock mass quality. The sea water entering the rock fractures is thought to have accelerated the weathering along the coastline.

Published: December 2024

Abstract
The Red Hill area in Bangka Regency, one of the largest former mining sites on Bangka Island, remains largely unreclaimed, presenting opportunities for sustainable rehabilitation. This study utilizes the Self-Potential (SP) method to map groundwater flow patterns as a foundation for post-mining reclamation efforts. SP data were collected along eight survey lines, covering 150-250 meters each, in the Ampar Lake area. The analysis reveals SP anomalies ranging from -117 mV to 86,696 mV, indicating significant variations in electric potential linked to groundwater movement. High-potential zones were identified as recharge areas, while low-potential zones indicate discharge areas, suggesting a regional groundwater flow from northeast to southwest. These findings establish a preliminary understanding of groundwater behavior in the Red Hill area, providing a basis for targeted reclamation to support agricultural, educational, and ecotourism initiatives.

Authors: Aldila H , Andini D E 
Published: December 2024

Abstract
Bangka quartz sand is a strategic mineral that contains relatively high levels of silicon compared to other sources of silicon minerals. The silicon content in a mineral greatly determines the feasibility of processing its derivative products, one of which is very well known, namely silica. Silica is a functional material that is widely applied in various fields including energy, environment, food and medicine. In this research, the silica extraction process has been carried out from Bangka quartz sand using the alkaline digestion method. The main extraction process stages include preparation, digestion using NaOH, water leaching, and calcination. The effect of varying calcination temperatures: 600, 800, and 1000°C on the silica phase and content of Si element was studied comprehensively. Based on the research results, it shows that at a temperature of 600°C, amorphous silica is formed, while at temperatures of 800 and 1000°C, crystalline silica with a quartz phase is formed with the element content of Si at 800°C reaching 98.87%.

Published: December 2024

Abstract

Osteochilus spilurus (Bleeker, 1851) is a consumption fish with important economic value for the people of Belitung Island. The exploitation of their capture from river has the potential to disrupt their natural population. The domestication of this fish has reached the first level and continues towards artificial spawning. The main problem in selecting broodstock is the difficulty in sorting male and female fish based on their morphology. Geometric morphometric is used to describe the morphometric and body shape of male and female of O. spilurus. In terms of morphometrics and body shape, O. spilurus exhibits a little amount of sexual dimorphism between males and females. The differ are on morphometrically of pre-anal length and body shape of the anal and caudal penducts. Due to their close resemblance, O. spilurus males and females cannot be chosen using secondary sexual characters for spawning and domestication of broodstock. Instead, primary features must be observed.

Published: December 2024

Abstract
One of the ecological crisis triggers is unethical behavior in the form of irresponsible consumption, which leads to resource wastage, energy leakage, and a high carbon footprint. Excessive consumption is the beginning of environmental problems as it generates large amounts of waste. Households are the economic sector that contributes the most waste, and demographically, young households tend to be active and have high consumption rates. The consumption behavior of this segment raises concerns as it puts pressure on the environment and sustainable development, which needs to be clarified in this study. This study tests a model of pro-environmental behavior, including environmental concerns and activism in shaping responsible consumption behavior. The model initiated in this research is by the actual phenomena that occur, so it is expected to produce essential insights for environmental planning and management based on aspects of consumer behavior as the main actors in the natural ecosystem.

Small islands and Outermost Small Islands (PPKT) in the waters surrounding Bintan and Tanjung Pinang, Riau Archipelago Province, have generally not been managed using an environmental approach, which has prevented them from functioning optimally as national assets. This research aims to explain the importance of managing Small Islands and PPKT in Bintan and Tanjung Pinang and their contribution to the practice of green diplomacy.
Environmental management through tourism development based on communal intellectual property (case in the Bangka Belitung islands)
Authors: Darwance  , Haryadi D , Sari R , Pratama S 
Published: December 2024

Abstract
The tourism industry is currently one of the industries that has an important role in the national development of various countries. The Bangka Belitung Islands, with their natural beauty, have an attraction as a tourist destination. On the other hand, environmental damage is still a major problem in this area, especially due to tin mining. Tin mining, which has been going on for a long time and is massive, has also been destructive and will continue to threaten the survival of local plants and animals. In the context of intellectual property, this is what is called communal intellectual property, which in the tourism industry is one of the attractions, and this has not been developed in this area. This research uses empirical judicial methods, conducting a study of environmental regulations and management efforts through the development of the tourism sector based on communal intellectual property, namely those that are directly related to the local environment. From the results of studies that have been carried out, there has been no direct effort to make environmentally based communal intellectual property a major part of the development of the tourism sector in the Bangka Belitung Islands. The environment, in some cases, is indeed one of the bases, but no one has truly made communal intellectual property the epicenter, such as presenting local flora and fauna. In fact, apart from being attractive, this is also an effort to enforce law from an environmental aspect.
Relationship between soil conditions and road quality degradation
Authors: Yofianti D , Wardanti A , Fahriani F 
Published: December 2024

Abstract
Roads are one of the infrastructures that are greatly needed by the community. One component of the road pavement structure is the subgrade. Road damage may be caused by a decrease in the quality of the subgrade. Therefore, this study aims to explain the relationship between soil conditions and the decline in road quality. The location of the study is on Jalan Lampur-Munggu, Lampur Village, Sungai Selan District, Central Bangka Regency. This study was conducted at STA 0+000 to STA 1+285 which were divided into 52 segments where the length of each segment was 25 m. Soil condition data was taken at 10 points. The results of the study showed that the road pavement condition index value obtained was 44.7, which is in the poor category. Furthermore, the California Bearing Ratio value for the soil conditions obtained was 8.08%, which is classified as quite good. It can be concluded for this case that the degradation in road quality is not affected by the California Bearing Ratio value of the subgrade. However, it is better to still consider other factors of soil conditions that can accelerate road damage.

Published: December 2024

Abstract
Research was conducted at the PT. Bukit Asam Air Laya Mine Site. The aim of the blasting activity is to explode the B2-C interburden layer in order to obtain Seam C coal. The drilling pattern used is a staggered pattern with a vertical drilling direction. The actual blasting geometry used is with a burden of 7 m, spacing of 8 m, hole depth of 8 m, stemming of 4 m, and powder column of 4 m. The level of blasting fragmentation for sizes greater than 160 cm based on theoretical calculations is 26.49 %, while the target set by the company for boulder fragmentation is no more than 20%. To reduce the level of fragmentation, changes were made to the actual geometry by conducting studies using the RL Ash, CJ Konya, and ICI Explosive theories. From this study, recommendations for the proposed blasting geometry were obtained with a burden of 6 m, spacing of 9 m, hole depth of 11.66 m, stemming of 5.14 m, and powder column of 6.52 m. With these changes in geometry, fragmentation measuring more than 160 cm was obtained at 17.15%, or it can be said to achieve the fragmentation target of less than 20%.
Opportunities and challenges of establishing a nuclear power plant in the Bangka Belitung islands province: juridical and sociological perspectives
Authors: Permatasari B , Situmorang A A C , Ferianda S 
Published: December 2024

Abstract
This study aims to analyze the legal aspects of using nuclear power in Indonesia and the challenges of developing nuclear power plants in the Bangka Belitung Islands Province from a legal and sociological perspective. The research method uses an empirical juridical method. Indonesia already has several regulations governing nuclear energy. However, existing rules cannot yet enable Indonesia to have its nuclear power plant. Apart from that, there are four primary keys to the nuclear legal framework—safety, security, safeguards, and liability for atomic losses. Indonesia must still improve its safeguard and security framework in regulating nuclear energy law. So, the law needs to be amended or replaced. Meanwhile, the opportunity to build a nuclear power plant is due to a regional regulation regulating the Bangka Belitung Islands Province Regional Regulation Number 13 of 2019 concerning the General Regional Energy Plan for 2019-2050 and the abundant potential for thorium. Meanwhile, the challenges are due to resistance from the WALHI community organization and several communities and the lack of regulations at the central level.
Impact of Maxwell–Cattaneo effect on thermal convection instability in vertical porous layer saturated with an Oldroyd-B fluid
Authors: Jia Beinan , Jian Yongjun 
Published: December 2024

Abstract
The investigation focuses on the Maxwell–Cattaneo (MC) effect on the thermal convection instability in a vertical porous layer saturated with an Oldroyd-B fluid. The MC effect modifies the conventional Fourier’s law for temperature by incorporating the upper convective Oldroyd derivative. The flow through the porous layer is modeled by the Darcy‒Oldroyd model. Using the Chebyshev collocation method addresses an Orr-Sommerfeld eigenvalue problem. Analysis of temporal growth rates reveals that the MC effect causes the originally stable flow to become unstable. Furthermore, the study finds double impacts of the MC effect on convection instability depending on whether it is primarily influenced by the fluid or the solid phase. Neutral stability curves highlight a critical threshold for the averaged Cattaneo number (Ca
) of both solid and fluid. When Ca
falls below this critical value, instability is suppressed, but when it exceeds this value, instability is magnified. The analysis also reveals that viscoelasticity parameters can impact the system by either stabilizing or destabilizing it. A rise in the retardation time parameter (λ
2) exerts a stabilizing influence, whereas an increase in the relaxation time parameter (λ
1) exhibits a destabilizing effect.
Dynamic feature separation domain generalization for bearing fault diagnosis
Authors: Cai Haichao , Yang Bo , Xue Yujun , Li Jubo , Xu Yanwei , Yang Xiaokang , Ye Jun 
Published: December 2024

Abstract
Domain adaptation is a research hotspot in the field of bearing fault diagnosis; however, extremely scarce bearing fault sample information limits the development of domain adaptation techniques. Thus, improving the generalization ability of fault diagnosis models is an urgent problem to be solved. Thus, this study proposed a dynamic feature separation domain generalization method for bearing fault diagnosis. The proposed method facilitated the dynamic adjustment of the influence of internal and mutual invariant features on the domain generalization process by learning the relationship between internal invariant features within the domain and mutual invariant features between the domains. This ensured the maximum utilization of invariant information in the features and obtainment of a domain-invariant bearing fault diagnostic model. Consequently, the fault diagnosis capability of the model was improved and the shortcomings of the poor generalization capability of existing models were alleviated. Finally, the effectiveness of the method was verified by comparing several bearing-fault datasets.

Abstract
Increased electrification of the transportation sector promises to both decrease emissions from the largest sector source of greenhouse gases as well as improve health through better air quality. The objective of this study is to evaluate the distribution of air quality health benefits of Medium- and Heavy-Duty Electric Vehicle (MHDEV) policies in New York City (NYC), quantifying differences across neighborhoods (census tracts) and population subgroups (race, ethnicity). We ran an integrated model for a 2040 baseline/business-as-usual scenario and for two policy scenarios simulating different rates of MHDEV adoption, also for 2040. Changes in air quality (fine particulate matter (PM2.5) and nitrogen dioxide (NO2)) and health and economic benefits were calculated for the two policy scenarios. We used a modified version of our previously developed ZIP Code-Level Air Pollution Policy Assessment tool which integrates two reduced form models: the Community Air Quality Tools and the Co-Benefits Risk Assessment Health Impacts Screening and Mapping Tool. Our air quality modeling employed a novel receptor network to capture sharp gradients due to medium- and heavy-duty vehicle (MHDV) emissions in the densely populated NYC region. We find that electrification of MHDVs would have substantial air pollution and health benefits for NYC, with full on-road electrification of MHDVs saving $2.4 billion in health costs in 2040, including the prevention of 248 deaths and 173 childhood asthma emergency departments visits. We find that NO2 benefits contributed between 85% and 97% of the total health benefits, emphasizing its importance for on-road health studies. We find that most health benefits would occur in neighborhoods with the highest percentage of historically marginalized populations, including substantial benefits to Hispanic populations.
