ASEAN in the Middle of US and Chinese Rivalry: ASEAN Cooperation with RCEP in Reducing the Impact of the Trade War
Authors: Ke Haren
Published: May 2022

Competition between the US and China over trade wars has a significant impact on many countries in the world, including ASEAN. The ASEAN region is a central market in the Pacific. Because of this competition, each Chinese export to the US will decrease by around 10%, and also reduce economic growth by 1.1% in ASEAN. This phenomenon raises significant questions about the role of ASEAN. This research paper will answer the purpose of ASEAN as a multilateral organization in balancing its interests amid a trade war. After that, this paper focuses on the topic of competition between the US and China related to the economy. This discussion is divided into two main points, first is about the trade war, and the second is the role of RCEP to build ASEAN economic balance. International cooperation on a liberal perspective is used to analyze the problems in this case. This paper argues that ASEAN seeks to encourage collaboration between its members to face the challenges of the US and China trade wars. Cooperation is the best way for ASEAN to see this phenomenon.
Entrepreneurship Courses’ Impact on Students’ Interest in Entrepreneurship
Authors: Primadona
Published: May 2022

The economic difficulties in 1998 with the monetary crisis that occurred in the transformation era caused a lot of unemployment in various places in Indonesia. The cause of this high unemployment is the imbalance of fairly high population growth with the few available jobs. This research then aims to see how entrepreneurship lectures for students can influence entrepreneurial interest. This research will be carried out using quantitative methods. Existing data will be analyzed using descriptive analysis and multiple linear regression. This study found that entrepreneurship lectures influenced students’ interest in doing entrepreneurship. The effects of this lecture are divided into two, namely the lecture material and how to deliver the material. The lecture material directly influences student interest, while the way this material is delivered does not directly affect student interest in entrepreneurship.
ANALYSIS OF THE FOREST APPROACH IN THE DISTRICT STRATEGIC PLANS OF THE GOVERNMENT OF MOZAMBIQUE
Authors: Teixeira Jerónimo Víctor
Published: May 2022

This paper analyzes how forests are addressed in local government plans and strategies. The overall objective is to better understand the importance given to forests in the economic development of the country. Specifically, the analysis on this theme seeks to answer the following questions: 1. What is the importance given to forest resources in local development plans? 2. To what extent, and how, are forests incorporated into plans at district level? 3. What is the role assigned to local communities (if any) in forest management based on the strategies analyzed? The methodology of this research was the textual analysis of the forest references as well as the importance given to this natural resource, based on the documents of the local development plans, namely at the district level. Results indicate that the local development plans reviewed recognize the importance of forest resources, but the focus varies from document to document. Among the priority actions presented by the documents, the participation of local communities in decision-making processes on forest use has not been addressed in most of these decision support instruments. The role of local governments in forest management is not explicit in most of the district strategies analyzed.

Authors: Chuks Madukasi Francis
Published: May 2022

In the depths of the human spirit resides an inclination or tendency to actually follow the same paths that has been long venerated by our ancestors. It is believed in African mysticism that travel is the spiritual food for the soul, especially when that spiritual journey takes us to another plane where our humble hearts illuminate. Journeys to sacred places like that of Menri tomb touch upon that which is significant to our spiritual inclination and humanity. These site seeing actually opens our mind set to the world around us, our whole history, the cosmos above and equally to each other. When one arrives at his spiritual destination, he find himself closer to his own personal/individual reality, not only in time, but in space. In Igbo belief system, something magical happens at the tomb of Menri in Aguleri that triggers an unconscious memory and to learn about the world of sacred places is to learn about ourselves. The journey to the Menri tomb which comes with its breeze of blessings after is highly surrounded with mysteries up till today. This paper examines how this Menri tomb becomes an indigenous sacred temple of mortality that binds the Igbo communities in ritual symbology of brotherhood and serves also as an epicenter for global tourism site in Igbo ontology

Pollution from the use of fuels like fuelwood and crop residue is a huge environmental issue in developing countries. It leads to poor indoor air quality and adverse impacts on human health, mainly that of women and children who spend most of their time indoors. It also leads to deforestation in areas where fuelwood and charcoal use is high. This chapter describes the problem of fuel use for cooking in developing economies, and the challenges they pose for human health and the environment. The findings from many economic studies are analysed on different aspects of this issue, evaluations of government policies and the difficulties associated with the desired transition to cleaner, more efficient fuels such as natural gas and electricity.
On the Application of Metaheuristics and Deep Wavelet Scattering Decompositions for the Prediction of Adolescent Psychosis Using EEG Brain Wave Signals
Authors: Nsugbe Ejay
Published: May 2022

Schizophrenia is a common psychotic disorder which affects a substantial amount of the population, where the paranoid variant is viewed as the most common form of the disorder. This form of psychosis has been seen to affect both adults and adolescents; where in the case of adolescents, it is increasingly challenging to diagnose with traditional means involving clinical interviews. The use of electroencephalography (EEG) signals has proven to be an effective means of non-invasively diagnosing brain disorders, alongside having the ability to mitigate any form of subjective bias from the diagnosis process. This paper explores the use of acquired EEG signals, metaheuristics and deep wavelet scattering decomposition, and a combination of supervised and unsupervised learning, for the automated prediction of adolescent schizophrenia. The results showed the best accuracy for the metaheuristic decomposition alongside the candidate learning methods, in the region of 95%+ across the various classification metrics, which showcases an enhanced means of prediction of adolescent schizophrenia. Further work would now explore the use of Long ShortTerm Memory and Convolution Neural Networks to investigate the classification performances.

Published: May 2022

Hydrocarbon contamination of the groundwater system is a problem facing residents of Ejigbo, Lagos, Southwestern Nigeria. The area hosts the busiest satellite petroleum depots in Nigeria, and residents have attributed pollution of the groundwater system to hydrocarbon spills from possible pipeline leakages. This study aimed to identify and characterize the source and extent of the groundwater system contamination in the study area. The electrical resistivity method was adopted, comprising 2D Electrical resistivity imaging (ERI) and Vertical Electric Sounding (VES) techniques. Data acquired were processed and analyzed to obtain geoelectric sections, longitudinal conductance map and 2D ERI sections for the study area. Three distinct geoelectric zones were delineated, with the intermediate zone identified as the contaminated shallow aquiferous unit. This unit's resistivity values ranged from about 400 - 5000 ohm-m at a depth of 5 - 35 m. On the 2D ERI sections, possible locations of pipeline leakages were identified. On some ERI sections, a linear feature with resistivity value less than 300 ohm-m was observed from the surface down the depth of the entire section, truncating the horizontal flow of the contaminated unit. Generally, the results indicate that the contamination of the shallow aquifer in the area is widespread and mitigation measures should be urgently undertaken.

Published: May 2022

The amount of secure data being stored on mobile devices has grown immensely in recent years. However, the security measures protecting this data have stayed static, with few improvements being done to the vulnerabilities of current authentication methods such as physiological biometrics or passwords. Instead of these methods, behavioral biometrics has recently been researched as a solution to these vulnerable authentication methods. In this study, we aim to contribute to the research being done on behavioral biometrics by creating and evaluating a user authentication scheme using behavioral biometrics. The behavioral biometrics used in this study include touch dynamics and phone movement, and we evaluate the performance of different single-modal and multi-modal combinations of the two biometrics. Using two publicly available datasets - BioIdent and Hand Movement Orientation and Grasp (H-MOG), this study uses seven common machine learning algorithms to evaluate performance. The algorithms used in the evaluation include Random Forest, Support Vector Machine, K-Nearest Neighbor, Naive Bayes, Logistic Regression, Multilayer Perceptron, and Long Short-Term Memory Recurrent Neural Networks, with accuracy rates reaching as high as 86%.
Preference or Pre-Emption Right for Cultural Objects
Authors: Ramos Jose Luis Bonifacio
Published: May 2022

Preference or Pre-emption Right means the power of one party to acquire a certain object to the detriment of another making an identical claim, we need to establish a distinction by looking at the different powers underlying this act of preferring. If there are many preferences, the pre-emption over cultural property, also known as artistic or cultural preference, is a true category among other preferences. After studying the exercising of pre-emption rights, as well as their respective consequences, about Portuguese Law, we must ascertain their effectiveness, not only in terms of their viability in the effective acquisition of objects but, and equally, the objectives which this aims to pursue in terms of achieving the protection of cultural heritage.

Application of Error Correction Codes RS and LDPC to Enhance the Dicode Pulse Position Modulation
Authors: Hussein Yasmeen M. , Al-Nedawe Basman M. , Mutlag Ammar Hussein , Jawad Ameer K.
Published: May 2022

Dicode Pulse Position Modulation (DiPPM) has been presented as a new coding technique with several improvements over earlier PPM formats. Few analyses and experimental results have been published because it is a new coding scheme. To overcome the problem of bandwidth utilization in current PPM formats, DiPPM can be employed. The line rate is twice as fast as the original data rate. In order to increase DiPPM's error performance, two types of Forward Error Correction (FEC) codes, Reed-Solomon (RS) code and low-density parity-check (LDPC) code, are investigated in this article. When RS and LDPC function at their optimal parameters, the results show an improvement in DiPPM system error performance. The error performance of an uncoded DiPPM system was compared to that of a DiPPM-encoded LDPC system and a system utilizing the Reed-Solomon algorithm. Transmission efficiency is measured by the number of photons per pulse and bandwidth widening. When the bandwidth is 1x103 times or more than the initial data rate, DiPPM with LDPC code exceeds uncoded DiPPM and DiPPM with RS, using 1.821 x 103 photons per pulse, with a codeword length of 27 and code rate of 0.75.

Published: May 2022

Ruta angustifolia is one of the species of Ruta genus that is widely used in Asia as traditional natural medicine, but scientific research related to this plant is still limited. Several studies have stated that this plant has an antimicrobial effect, but no studies have discussed the antibiofilm effect of bioactive compounds isolated from R. angustifolia. This study is the first to address this issue. This study aims to see whether the bioactive compounds isolated from R. angustifolia can inhibit the formation of biofilms on oral microbes that play the most important role in the construction of dental caries, namely Candida albicans and Streptococcus mutans. Isolation and identification of bioactive compounds is achieved through Thin Layer Chromatography, Liquid Chromatography with tandem mass spectrometry, and proton nuclear magnetic resonance, respectively. Crystal Violet (CV) method is used to see the total biomass of biofilm, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) method is used for the viability test. The morphological visualization of C. albicans has also been carried out using a light microscope and a scanning electron microscope. Three compounds that have been isolated are kokusaginine, chalepin, and lindelofine. The CV and MTT data were compared with the control data using an analysis of variance test followed by the Tukey honestly significant difference test, while the morphological data is qualitatively analyzed. From the results of the biofilm test, it was concluded that the three compounds could significantly inhibit the formation of biofilms produced by C. albicans and S. mutans in mixed species cultures.

Authors: My Sang Tang , My Ha Tang
Published: May 2022

The good implementation of social responsibility by businesses not only helps the bank to develop sustainably but also contributes to the sustainable development of society. This research aims to investigate the relationship between social responsibility and commercial bank performance in Vietnam, specifically, to determine the magnitude and trend of factors' impact on profitability. Then, provide implications for solutions to strengthen the bank's social responsibility initiatives while also increasing the bank's profitability. The research investigated the impact of corporate social responsibility on bank performance in Vietnam by collecting secondary data from 17 banks listed on two exchanges, HOSE and HNX, from 2015 to 2020 in Vietnam. The findings show that most banks in Vietnam are giving more and more attention to corporate social responsibility activities, with all banks paying special emphasis to human resource activities. Quantitative research results have shown that bank performance is related to financial leverage, bank size, and social responsibility activities related to human resources. Three groups of related solutions have been proposed to increase the bank's performance from the research results. The research novelty lies in the relationship between corporate social responsibility and bank performance of listed banks.

Authors: Sophian Alfi , Abinawanto
Published: May 2022

Analysis studies of Co1 and BIK BCL2 genes in local Gorontalo chickens were carried out using real-time PCR. This study aims to detect the presence of Co1 and BIK BCL2 genes in local Gorontalo chickens so that they can be used as information on gene diversity that can be used as genetic markers to study the diversity of local chicken species in Indonesia. The method used in this study is the SYBR green real-time PCR method. The research conducted found that the concentration values of the extracted samples were in the range of 68.15-68.30 ng/µL. Meanwhile, the purity values measured at wavelength A260/A280 were obtained with purity ranges between 1.867-1.923. The amplification results of the Co1 target gene show that the Ct value is in the range of 20.90-21.20, while for Tm, it is 84.10-84.20. In the BIK BCL2 target gene analysis, the Ct value was in the range of 16.15-16.20, while for Tm, it was 91.10-91.20. From these results, it can be concluded that all research samples were sampled from six different regions detected with CT and Tm values from the real-time analysis carried out obtained homogeneous values and no more than 2 degrees of difference between samples. The research novelty was using Nisi chicken as the native, one of the local chickens in Indonesia as the object of study. Besides, we used a BIK BCL 2 gene as the marker to determine the genetic diversity of the local chicken. A suggestion for further research is to explore more diverse genes to obtain more data on genetic diversity.

Eucheuma cottonni cultivation has been a major source of income among residents of Kemojan Island. Expansion of seaweed cultivation area in Kemojan Island waters needs to be anticipated by analyzing the carrying capacity of the aquatic environment. Studies on the environmental carrying capacity of seaweed (E. cottonni) cultivation on Kemojan Island has never been conducted. This study aims to estimate the carrying capacity of the aquatic environment on Kemojan Island for seaweed cultivation. We have combined BOD5, tropic saprobic index (TSI), and regression to estimate the carrying capacity of the coastal environment for seaweed cultivation. There were 5 observation stations in this study. The measurement resulted in TSI values that ranged between 2.43 to 7.43 (slightly polluted to unpolluted categories) and BOD5 values between 2.6 to 5.4 ppm (below the sea waters pollution threshold). The total estimated area capacity that can be developed for E. cottonni cultivation was approximately 86.2 ha (sea waters) with a potential production of 7,392 tons (wet weight) per year and economic value reaching IDR 11.09 billion.

Reprocessing plastic waste to become fuel oil is a good process. Plastics were originally obtained from the polymerization of petroleum products. According to SIPSN data from the Ministry of Environment in 2020, plastic waste in Indonesia has reached 17.314 million tons/year. In addition to using recycling, reduction can be made using hydrothermal pyrolysis cracking to convert solid plastic waste into liquid gasoline fractions with the help of co-reactants. However, with the pyrolysis process, the final result of the process allows the presence of impurities that are still contained in it. In this research, the distillation of the pyrolysis results for gasoline fraction plastic waste was carried out using a fractionated distillation column. The distillation process enhances the performance of petroleum oil with an average of RON 98 and a caloric value of 10,609,7 cal/gr. Modeling and simulation using excel of the distillation results of pyrolysis were carried out, it was found that the increase in the reflux ratio led to an increase in the purity of the distillation product and the effect of residence time caused the longer the process to run, the lower the distillation product. Therefore, the separation should not be done too long, which can cause the purity to decrease every time. The higher the reflux ratio, the smaller the kinematic viscosities get proven by experimental and modeling, but the value is a striking difference due to deviation from the model.

Technological advancements create favorable conditions for the world of sports, demonstrating the strength and management of sports through technology. In the 4.0 era, the sports evaluation process is digital already. The test instrument to measure leg muscle power is still done manually today, so a digitally based conceptual design of the leg muscle power instrument is required. Jump power meter (JPM) based on integrated digital technology is an innovative test instrument for limb muscle power with modern technology and the practicality of inputting data. However, for further development, a design assessment by an expert should be carried out. This study aimed to develop a digital-based integrated JPM conceptual design to measure leg muscle power, then tested for content validity and inter-rater reliability. A qualitative and quantitative research method was used with documents and five experts. The first stage of this study was document analysis and field observations, followed by data collection using the Delphi technique in the second stage. The rating scale used was 1-5. The content validity formula for this research was Aiken. Reliability was tested using Cronbach Alpha, while interclass coefficient correlation was used to test the conceptual design of JPM. The study found that the conceptual design of the test instrument to measure jump power could be used to measure an athlete's leg muscle power. Based on the findings of this study, the Aiken coefficient was in the range of 0.85-1.00, with Cronbach Alpha reliability of 0.587>0.6. Meanwhile, the ICC agreements of one rater and between raters are 0.221 and 0.586, respectively. As a result, it can be concluded that the instrument has a high level of content validity and reliability in all aspects.

This research was motivated by the deradicalization of ex-terrorist convicts. It requires understanding the development of radicalization and sociological aspects, e.g., community acceptance and rejection of ex-terrorist convicts. One of the efforts to return ex-terrorist convicts to the community is developing their potential in creative economic activities. This study aimed to evaluate entrepreneurship training for ex-terrorist convicts to improve their creative economy management skills. The research approach employed in this study is a descriptive evaluation of the implementation of entrepreneurship training for ex-terrorist convicts to develop creative economy management abilities, which is specifically designed for them. This research novelty is training ex-convicts as a form of self-development and a solution for them to be entrepreneurs; besides, they can readjust to society according to the rules and norms that apply. In this study, the data sources were ex-terrorist prisoners chosen randomly to participate in entrepreneurship training designed beforehand. According to the study results, the entrepreneurship education model is suitable for developing the entrepreneurial spirit of the creative economy and national insight as a deradicalization strategy with multiple economic, social, and cultural benefits. Ex-terrorist convicts are occupied with economic activities, accompanied by increased national awareness. Their public acceptance, on the other hand, will increase.

Lake is a water source that has decreased its function and has damaged the ecosystem. The Mahakam cascade lake in the East Borneo-Indonesia consists of Jempang Lake, Semayang Lake, and Melintang Lake, which have the sedimentation problem caused by the land-use change. The sedimentation can cause floods in the Mahakam River. However, the Mahakam River that correlates with the Mahakam cascade lake cannot reduce the happened flood. This study intends to optimize flood reduction modeling of Mahakam Cascade Lake towards the Mahakam River in the Muara Kaman outlet. According to the optimization model, this research aims to simulate the flood reduction modeling due to the 3 discharge conditions: Q25, Q50, and Q100. The food reduction modeling uses the Linear Programming Model, and the model is built integrated due to the Cascade Lake. The methodology consists of a linear programming optimization model due to the 3 scenarios (Q25, Q50, and Q100). However, the analysis of the design flood uses the Nakayasu Synthetic Unit Hydrograph in the watershed and the Rational Method for the discharge in the lake. The capacity of Mahakam Cascade Lake due to the bathymetry data and AWLR is as follow: 1) Jempang Lake: 519,958,550.36 m3; 2) Melintang Lake: 696,012,192.74 m3; and 3) Semayang Lake: 1,195,593,435.86 m3. The optimization model result of flood reduction in the Muara Kaman is as follow: a) Scenario-1 (Q25): Qmuara Kaman = 32,729.80 m3/s; b) Scenario-2 (Q50): Qmuara kanam = 37,432.36 m3/s; and c) Scenario-3 (Q100): Qmuara kanam = 39,777.80 m3/s.
Use of Impact Penetrometer to Determine Changes in Soil Compactness After Entracon Sioux EH30 Timber Harvesting
Authors: Kormanek Mariusz
Published: May 2022

Wood harvesting with the use of wheeled harvesters is now common in Polish and Czech forests. While moving in the forest, the wheels of these machines affect the forest soil and the extent of this impact is interesting. The paper presents the results of measurements of the changes that occur in the soil on the operational trails after the timber harvesting using the Entracon Sioux EH30 thinning harvester. The measurements were taken on fragments of three operational trails, in and between the ruts and at a distance of 1.0 m off the trail. An impact penetrometer was used to measure the penetration resistance, soil samples were collected to determine the bulk density and moisture content, and soil deformations on the trail were measured with a profile meter. Unit pressures exerted by harvester wheels on the ground were determined. It was shown that in the places where the harvester wheels pass, even of a small weight (5.73 tons, 8 wheels) and with unit pressures of the wheels on the ground <50 kPa, changes in soil parameters occurred. A statistically significant increase in penetration resistance in relation to the control occurred at a depth of up to 35 cm, while at a depth of up to 5 cm the increase was more than 2-fold. There was also a slight decrease in soil moisture content (up to 7.9%) and an increase (up to 8.4%) in bulk density in the ruts, while rut depths were small and reached 4 cm. As it was shown, the impact penetrometer, simple in design, which was assumed to be used for measurements, and which is not used in this type of research in forestry, despite its limitations, can be used to determine the compactness of the soil and its changes resulting from machine work.

It is well-known that soil and water conservation actions (e.g., installing water diversion structures) are necessary to restore skid trails after logging operations. However, there are some points that have yet to be determined concerning the efficacy of rehabilitation on sediment yield and nutrient export to the aquatic environment. The objectives of this study were to determine the optimal distance among the water diversion structures (WDSs) to suppress runoff, sediment yield, and measure nitrogen and phosphorus concentrations on the skid trails of a mountainous ecosystem. The study was conducted on a total of 18 bounded runoff plots, each with a width of 4 m and a length of 120 m, divided into six treatment compartments done in triplicate. Beech logs were placed at a distance of 5, 10, 20, 30, and 40 meters. An untreated area (U) was set up during the recording period from 18 September 2015 to 17 September 2016. In all the WDS treatments and untreated trails (U), the observed peaks of runoff, sediment yield, as well as nitrate and phosphate concentrations was found to be significantly correlated with the amount of rainfall events. Results show that there was a decrease in surface runoff and runoff coefficient, sediment yield, and nitrate and phosphate concentrations by installing of WDS at different distances. The runoff and runoff coefficients (2.67 mm and 0.101, respectively) were at the lowest level in the WDS20 (WDS at a distance of 20 m). The sediment yield was significantly higher on the U, 13.52 g m-2 followed by WDS40, whereas the lowest values were detected at the WDS10. Significantly higher values of nitrate were found in the U (3.63 mg l-1), while the lowest amounts of nitrate were determined at WDS5 followed by the WDS20 treatment. The highest values of phosphate were found on the U treatment (0.278 mg l-1) followed by the WDS40 treatment, whereas the lowest phosphate values were measured in the WDS20 treated area. Therefore, it can be deduced that the recommended water diversion structure should be placed at a distance of 20 m to mitigate runoff, sediment yield, nitrate and phosphate exports on the skid trails.
A Mathematical Model of Solid Waste Accumulation and Treatment with a Varying Human Population Size
Authors: Rukundo Isaac , Ariho Pius
Published: May 2022

Solid waste management has continued to be an increasing challenge worldwide and the situation has become worse in urban areas of developing countries. The rapid urban population growth, mainly due to high immigration and birth rates, has led to large amounts of solid waste, making it difficult for authorities to effectively manage the accumulated waste. Existing mathematical models of solid waste accumulation consider solid waste management by an external effort and do not address the contribution of the population in the management process. In this study, a mathematical model of solid waste accumulation is developed and analysed incorporating parameters for human immigration and solid waste recycling by particular population age groups. The solid waste is considered to be of two categories: biodegradable and non-biodegradable. Existence of equilibrium points is established and their stability analysed. Numerical simulations are done using MATLAB and Maple. Results show that solid waste increases with increasing human population and thus a solid waste free environment cannot be achieved. Sensitivity analysis suggests that improving the biodegradability of solid waste coupled with aiding solid waste decay and recycling reduces the final size of solid waste.
