The impact of forest degradation due to open-pit mining activities causes sustainable ecological damage. Mining activities that are not organized due to the mineral exploration process have resulted in many forest areas experiencing degradation. This degradation certainly reduces the level of carbon sequestration in the area, impacting the sustainability of environmental functions around the mining area. The high carbon stock (HCS) approach is a way to help companies implement their 'no deforestation' commitments. The high carbon stock approach will identify forests that must be protected and land that can be developed. Forests with high carbon stocks are maintained because they function as carbon stores, habitats for biodiversity, and provide the necessities of life for local communities. Therefore, this study aims to obtain data on the potential for carbon stocks and create a spatial model for distributing carbon content in the concession area of PT. Vale Indonesia can later be determined as high conservation value (HCV) areas using the high carbon stock approach. Measurement of carbon content in the study used an allometric equation that has been developed, then the distribution of carbon was made using the spatial vegetation index model obtained from Sentinel 2 imagery. The results showed an area of 30,526.49 (42.97%), which had high carbon stock with an average carbon stock of 106.09 ton/ha, which needed to be maintained as an area of high conservation value in the mining area of PT. Vale Indonesia.

The adoption of e-wallet service is on the rise among Indonesian customers. People use e-wallet because it is convenient, more secured, and offers advantages over physical cash. In line with the growth of e-wallet adoption, the number of e-wallet services in Indonesia has increased to more than 50 providers in 2020. This situation leads to a competitive market in e-wallet service. This study examines key factors affecting customer satisfaction and continuance intention to use e-wallet services and applications based on the integration of Diffusion of Innovations (DOI) theory, Technology Acceptance Model (TAM), and Expectation-Confirmation Theory (ECT). The data collected from 663 participants were analyzed based on structural equation modeling partial least square. The results show that confirmation, perceived ease of use, compatibility, and trialability have positive impacts on customer satisfaction, and perceived usefulness, satisfaction, and habit contribute to continuance intention on e-wallet. In addition, customers prioritize security over ease of use when using e-wallet and consider it part of e-wallet usefulness. Based on findings, this study recommends strategies to maintain customer’s satisfaction and to increase continuance intention, such as security prioritization on e-wallet, a customized promotion for each customer, application update based on customer’s feedbacks, and market expansion to include small and medium enterprises (SMEs).

AIP Conference Proceedings 2021年第1期2329卷

作者： Ira Puspitasari Rohiim Ariful Barry Nuqoba 1Information System Study Program Faculty of Science and Technology Universitas Airlangga Surabaya 60115 Indonesia 2Research Center for Quantum Engineering Design Faculty of Science and Technology Universitas Airlangga Surabaya 60115 Indonesia

Dengue Hemorrhagic Fever (DHF), an acute capillary leak syndrome caused by dengue virus, is one of the major public health problems in Indonesia. Several major DHF outbreaks have occurred, and the incidence rate has increased from year to year. The increasing use of social media for health-related activities and the geolocation social media data can be leveraged to enhance the current surveillance system for controlling communicable diseases, including DHF. This study explores Instagram, one of the most popular social media in Indonesia, to analyze posts about DHF toward improving the surveillance system. We extract Instagram posts in 2017 - 2018 with geolocation and date-time value, that contained one or more DHF keywords in Indonesian language (i.e., demam berdarah dengue, demam berdarah, dengue, Aides aegypti, and fogging), resulting in 665 posts in dataset 2017 and 976 in dataset 2018. The preprocessing of the dataset includes tokenization, word normalization, stop word removal, stemming, and building the term-document matrix. The training dataset is labeled into news, education and information, and other classes, and the K- nearest neighbors (KNN) is applied to classify the DHF posts. The accuracy of the KNN classifier is 71% for the 2017 dataset and 77% for the 2018 dataset. For the deployment, we perform spatial analysis and compare the results with the actual DHF cases from the Ministry of Health of Indonesia. The spatial analysis results report that 17 provinces reveal similar changes between the number of DHF posts on Instagram and the number of actual cases from 2017 to 2018, while 17 other provinces reveal the opposing changes. The results and findings of this study show that Instagram posts may contribute to enhance the current surveillance system. For example, the frequency of Instagram posts and its sharp increase may indicate unusual events about the DHF situation in a specific province.

MnBi2Te4 (MBT) is the first intrinsic magnetic topological insulator with the interaction of spin-momentum locked surface electrons and intrinsic magnetism, and it exhibits novel magnetic and topological phenomena. Recent studies suggested that the interaction of electrons and magnetism can be affected by the Mn-doped Bi2Te3 phase at the surface due to inevitable structural defects. Here we report an observation of nonreciprocal transport, i.e. current-direction-dependent resistance, in a bilayer composed of antiferromagnetic MBT and nonmagnetic Pt. The emergence of the nonreciprocal response below the Néel temperature confirms a correlation between nonreciprocity and intrinsic magnetism in the surface state of MBT. The angular dependence of the nonreciprocal transport indicates that nonreciprocal response originates from the asymmetry scattering of electrons at the surface of MBT mediated by magnon. Our work provides an insight into nonreciprocity arising from the correlation between magnetism and Dirac surface electrons in intrinsic magnetic topological insulators. © 2022, CC BY.

Cryptography is the science and art of maintaining the security of messages when messages are sent from one place to another. One of the ways securing the form of text message information is by the encryption process using the Vigenere Cipher algorithm and utilizing the One Time Pad (OTP) algorithm as a key generator, where the message will be random when it is opened. The message encryption process used the vigenere cipher algorithm while OTP is used to secure the key with the same formula. After this research has been done, an application was designed to secure text messages by converting the text message into a random message so that the message was unreadable due to a secret message that could not be known by others. The results achieved can secure an encrypted message that cannot be reopened and if those messages were reopened, they must be decrypted. © Published under licence by IOP Publishing Ltd.

The East Java Province has experienced a significant surge in number of confirmed cases of COVID-19. This study endeavors to investigate the potential correlation between weather conditions and the incidence of number of confirmed cases of COVID-19 in East Java. To achieve this, a nonparametric regression model, specifically, the Negative Binomial Regression (NBR) model based on the least squares spline estimator, was utilized. The outcomes of the study indicate that the Mean Absolute Percentage Error (MAPE) of nonparametic regression model is 0.30. Meanwhile, the MAPE for the parametric regression model is 0.34. The results show that a nonparametric regression model approach is better than parametric regression model approach. The study establishes that the truncated spline estimator based NBR model represents the best fit, with an MLCV value of -256.71. The findings of the study suggest that a temperature less than 21.75°C is associated with a decrease of 13.28 number of confirmed cases of COVID-19 per each 1°C increase, while a temperature between 21.75°C and 25.78°C is linked to an increase of 6.85 number of confirmed cases of COVID-19 per each 1°C increase. In contrast, a temperature greater than 25.78°C is associated with a decrease of 139.42 number of confirmed cases of COVID-19 per each 1°C increase. Similarly, a wind speed less than 5.57 m/s is related to a decrease of 12.99 number of confirmed cases of COVID-19 per each 1 m/s increase, whereas a wind speed between 5.57 m/s and 8.99 m/s is associated with a decrease of 10.29 number of confirmed cases of COVID-19 per each 1 m/s increase. Furthermore, a wind speed greater than 8.99 m/s is linked to a decrease of 19.16 number of confirmed cases of COVID-19 per each 1 m/s increase. The study provides evidence that higher temperatures and wind speeds result in a slower rise in the incidence of the number of confirmed cases of COVID-19. Consequently, it is recommended that the local government remains vigilant du

The associative property of addition facilitates the change of the group member. If the group members are molecules, can we apply this property to study a chemical reaction? The aim of this paper is to use the associative property of addition to design reaction pathways of methyl acetate hydrolysis in the acid environment. The reaction is found in Alzheimer’s Disease. We evaluate the designed pathways using activation energy obtained from density functional theory calculation. The results show the associative property of addition can be used to design four reaction pathways of the hydrolysis. The calculations show the acidity significantly affected the activation energy. This result agrees with the common knowledge. Hence, we have demonstrated the usefulness of the associative property of addition in designing chemical reaction pathways.
