Published: June 2022

The COVID-19 pandemic not only causes health problems but also affects the level of social trust. Low social trust occurs in the public sphere and transforms in the digital space. This situation was then deemed necessary to rebuild social capital. This study aims to prove that there are still opportunities in times of crisis where social capital can be re-formed, depending on how social networks initiate voluntary activism on social media. This study used a quantitative approach. Data were collected from Twitter using Ncapture. The data including information on COVID-19 cases were later analysed using the Nvivo 12 Plus software. This study found that there is a possibility and opportunity that low social trust caused by the COVID-19 pandemic can still be restored in times of crisis, at least by utilizing social media as a social networking center. Social networks on Twitter slowly shape cooperative behavior and social trust, and influence collectivities in rebuilding social capital.

Published: June 2022

Fokus topik artikel ini adalah pada aspek filosofis Hukum Islam dalam praktik asuransi syariah berbasis Multi Level Marketing (MLM) dari sudut pandang Maqasid Al-Syari'ah Jasser Auda, dimana asuransi adalah proses dari penanggung yang menyerahkan tanggung jawab kepada tertanggung dalam bentuk takaful. Proses pemasarannya biasa dilaksanakan dengan prinsip keagenan, namun tidak menutup kemungkinan proses ini bisa menggunakan penjualan langsung berjenjang dengan istilah lain Multi Level Marketing (MLM). Persoalan penting yang kemudian muncul, bagaimana status hukum penanggung pertama kepada penanggung kedua? Persoalan ini akan dipecahkan dengan pendekatan filosofis, dengan mengkaji seluruh proses penjualan jasa asuransi. Penelitian ini merupakan study kepustakaan (library reseach). Hasil penelitian menemukan bahwa implementasi asuransi syari’ah berbasis Multi Level Marketing (MLM) bisa dilaksanakan dengan dua konsep. Pertama, secara proporsional perusahaan asuransi hanya menyediakan produk asuransi sebagai cending company (upline), kemudian posisi konsumen lainnya menjadi member (downline) dan seterusnya kebawah. Kedua, diimplementasikan sebagaimana perusahaan jasa reasuransi, dimana perusahaan reasuransi juga mempunyai tata kerja yang bersifat dan lazim berlaku secara internasional, yang meliputi bentuk-bentuk reasuransi dan metode terjadinya reasuransi. 2) Implementasi asuransi syari’ah berbasis Multi level Marketing (MLM) dalam perspektif Maqashid Al-Syari’ah Jasser Auda bahwa nilai-nilai yang terkandung dalam pola pertama dan kedua dalam sistem pemasaran asuransi syari’ah dengan Multi Level Marketing (MLM) tergantung dalam kontrak perjanjian yang di atur antara cending company dengan para member di bawahnya dengan menekankan pada aspek kognitif, Utuh (Wholeness), Openness (Self-Renewal), Interrelated Hierarchy, Multi-dimensionality, Purposefulness.

Objective: From September 10 to 13, 2021, the finals of the BCI Controlled Robot Contest in World Robot Contest 2021 were held in Beijing, China. Eleven teams participated in the Algorithm Contest of Calibration-free Motor Imagery BCI. The participants employed both traditional electroencephalograph (EEG) analysis methods and deep learning-based methods in the contest. In this paper, we reviewed the algorithms utilized by the participants, extracted the trends and highlighted interesting approaches from these methods to inform future contests and research recommendations. Method: First, we analyzed the algorithms in separate steps, including EEG channel and signal segment setup, prepossessing technology, and classification model. Then, we emphasized the highlights of each algorithm. Finally, we compared the competition algorithm with the SOTA algorithm. Results: The algorithm employed in the finals performed better than that of the SOTA algorithm. During the final stage of the contest, four of the top five teams used convolutional neural network models, suggesting that with the rapid development of deep learning, convolutional neural network-based models have been the most popular methods in the field of motor imagery BCI.
Spoofing Attack Mitigation in Address Resolution Protocol (ARP) and DDoS in Software-Defined Networking
Authors: Jamil Harun , Ali Abid , Jamil Faisal 
Published: June 2022

Software Defined Networking (SDN) shows network operations to be performed for efficient network operations. Due to the increase in network devices, the percentage of attacks is also increased, and it is challenging to provide defense against such attacks. In SDN, the control plan is separated from the data plane. The control plan is implemented using some central devices called SDN controllers. In SDN Address Resolution Protocol (ARP), spoofing and Distributed Denial of Services (DDoS) attacks are carried out on an enormous scale. These are commonly launched attacks in SDN. Due to these attacks, the network performance is down, and network services are dead. This paper proposed a new auto detection methodology to detect ARP and DDoS attacks and mitigate SDN networks from these attacks.

Additionally, we implemented two algorithms: one for flow rules and the second for attack detection. An individual server was installed to check the malicious traffic installation. We present the new forward flooding rules to detect and mitigate attacks. The experiments are performed using LINUX-based network implementation. Our proposal successfully improves network security and enhances network efficiency.

Authors: Nugraha Suci , Poerwandari Elizabeth Kristi , Utoyo Dharmayati B. 
Published: June 2022

Religiosity in studies of sociology and psychology of religion is generally measured by using a scale constructed for a particular religious tradition. The Centrality of Religiosity Scale (CSR) developed by Huber & Huber (2012) is a religiosity measure scale that can be used by adherents of different religions. Research on religiosity in heterogeneous Indonesian society requires an instrument that can be used by various religious adherents. The purpose of this study is to translate and test the reliability and validity of CSR from English to Indonesian. The translated CRS is a 15-item version that is divided into 5 dimensions, namely ideology, knowledge, experience, public worship, and private worship. This study was conducted in 2 stages. It began with translating the English version of the CRS-15 measuring instrument into Indonesian which was carried out using the back forward translation method from Brislin (1980). The next stage was to test the psychometric appropriateness of CRS-15 using confirmation analysis which was conducted on data from 328 research respondents who were recruited using a convenient sampling technique. The results of statistical analysis showed satisfactory reliability results (α=.787). In addition, it was also indicated that the Indonesian version of the CRS consists of 14 items and could be used in studies of religiosity in Indonesian-speaking communities.

Abstract. This work deals with the synthesis of nanoparticles of iron-potassium diphosphate, KFeP2O7, implanted on activated carbon produced from corncob debris. The chemical composition and structure of activated carbon/potassium-iron diphosphate (AC/KFP) composite was analyzed by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Complementary tests were conducted to determine surface characteristics such as surface area and point of zero charge (pHpzc). Further, the acid-base titration enabled to determine the surface sites density of AC/KFP composite. Adsorptive properties of AC/KFP composite vis à vis U(VI) was then tested using the batch method.

Resumen. Este trabajo presenta la síntesis de nanopartículas de difosfato de potasio-hierro, KFeP2O7, implantadas sobre carbón activado preparado a partir de restos de olote de maíz. La composición química y la estructura del compósito de carbono activado/difosfato de potasio-hierro (AC/KFP) se analizó mediante Difracción de Rayos X, Microscopía Electrónica de Barrido y Microscopía Electrónica de Transmisión. Se realizaron pruebas complementarias para determinar las características de la superficie, como el área de la superficie y el punto de carga cero (pHpzc). Además, la valoración ácido-base permitió determinar la densidad de sitios de superficie del compósito AC/KFP. Adicionalmente, las propiedades adsortivas del compósito AC/KFP frente a U (VI) fueron evaluadas utilizando el método de lotes.
Aluminum Clusters (N=2-6) on CTF-0 Monolayer for Adsorption of Atrazine: Investigated by Density Functional Theory
Authors: Ibarra Rodríguez Marisol , Sánchez Mario 
Published: June 2022

Abstract. We present a theoretical investigation of the structural characteristics and stabilities of neutral and positively charged aluminum clusters Aln n= 2-6 on covalent triazine frameworks (CTF-0). We found that clusters are adsorbed on the CTF-0 with adsorption energies of 26.32 – 91.53 kcal/mol. All calculations showed that the interaction between the aluminum cluster and CTF-0 is strong and prefers to adsorb in the central cavity of the monolayer with Al-C 2.03-2.92 Å and Al-N 1.89-2.12 Å bond formation. Next, we calculated the adsorption of an atrazine molecule on the [AlnCTF-0] n=2-6 systems. It is found that an atrazine molecule is physically adsorbed only on three systems, [AlnCTF-0] n=3-4,6 with adsorption energies in the range of 30.68 to 61.08 kcal/mol. The NBO analysis reveals that aluminum atoms accept electron density from nitrogen of atrazine molecule, but they also return electron density to the atrazine molecule. Although this result suggests that the [AlnCTF-0] n = 3-4,6 systems can be used as a promising candidate to remove the atrazine molecule.

Resumen. Presentamos una investigación teórica de las características estructurales y las estabilidades de los cúmulos de aluminio cargados positivamente y neutros Aln n = 2-6 en el fragmento de triazina covalente (CTF-0). Encontramos que los cúmulos se adsorben en el CTF-0 con energías de adsorción de 26.32 a 91.53 kcal/mol. Todos los cálculos mostraron que la interacción entre el cumulo de aluminio y CTF-0 es fuerte y prefiere adsorberse en la cavidad central de la monocapa con formación de enlaces Al-C 2.03-2.92 Å y Al-N 1.89-2.12 Å. Seguido, calculamos la adsorción de una molécula de atrazina en los sistemas [AlnCTF-0] n=2-6. Se encuentra que una molécula de atrazina se adsorbe físicamente sólo en tres sistemas, [AlnCTF-0] n=3-4,6 con energías de adsorción en el rango de 30.68 a 61.08 kcal/mol. El análisis NBO revela que los átomos de aluminio aceptan la densidad de electrones del nitrógeno de la molécula de atrazina, pero también devuelven densidad de electrones a la molécula de atrazina. Estos resultados sugieren que los sistemas [AlnCTF-0] n = 3-4,6 pueden usarse como candidatos prometedores para remover la molécula de atrazina.

Authors: Khrebtiy Yaroslav V. 
Published: June 2022

The aim. Treatment of venous thromboembolism remains perhaps the most challenging problem of modern phlebology. The aim of our study was to analyze current data and guidelines on the use of surgical and minimally invasive approaches in the treatment of pulmonary embolism (PE) and to compare these with our own results.
Materials and methods. The results of treatment of 168 patients with PE, who underwent inpatient treatment at the clinic from 2009 to 2021, were analyzed. Among them, 162 (96%) patients had deep vein thrombosis, in 6 patients the cause of PE could not be identified. Recurrent PE was observed in 2 patients. PE with a high risk of death was observed in 51 (30.3%) patients, with a medium and low risk of death in 117 patients (69.6%).
Systemic thrombolysis was performed in 44 (26%) cases. In 5 (2.9%) cases, vena cava filters were implanted. One (0.6%) patient underwent aspiration thrombectomy of the pulmonary artery using an Aspirex catheter. Two (1.1%) patients underwent pulmonary artery thrombectomy using an artificial circulation device.
Results. Significant improvement in patients treated with thrombolytic therapy was observed in 40 (92.8%) cases. After surgical treatment of PE, significant improvement was observed in 100% of cases, 2 patients after PE showed complete de-obstruction of the pulmonary artery. No hemorrhagic complications were observed during the study period. No fatalities were reported. No recurrent PE was observed during the study period.
Conclusions. The choice of treatment for PE is determined by the degree of the impact on the pulmonary tract, the stability of the patient’s condition, indicators of dysfunction of the right heart, the period from the onset of the disease, the risk of death.
The use of aspiration thrombectomy using an Aspirex catheter (Straub, USA) and pulmonary artery embolectomy in the absence of thrombolytic therapy allows to obtain satisfactory results in patients with PE.

Abstract
Road construction often experiences problems during its construction, including in areas of expansive soil type, swelling soils, and soft soil. In Banjarmasin generally, the problem that is often faced is the construction of roads on soft clay soil. PET (Polyethylene Terephthalate) plastic waste is very common in Banjarmasin. Plastic waste is thrown away and is rarely used as an alternative solution to problems in infrastructure and other fields. This study, using PET (Polyethylene Terephthalate) plastic waste for the stabilization of soft clay soil in the city of Banjarmasin. The composition of the mixture is 1%, 3%, and 5% PET plastic waste from the total weight of the soil sample. While the size of plastic waste is varied with sizes 0.5x0.5 cm, 1x1 cm, and 2x2 cm. The purpose of this study was to determine the value of the physical properties and the value of the soil shear strength and the value of the free compressive strength of the soil before and after the addition of PET plastic waste. From the results of UCT and Direct Shear testing with PET pieces of various sizes, it can be seen that the larger the size of the PET pieces, the higher the free compression test value. The highest free compressive test value was obtained in the soil mixture with pieces of 2.0 cm x 2.0 cm with a mixture of original soil + 3% pieces of PET waste, which was 1.366 kg/cm2.
