Published: July 2022

ABSTRAKKondisi kendaraan yang saling bergerak pada sistem komunikasi Vehicle-to-Vehicle (V2V) menyebabkan daya sinyal yang diterima berfluktuasi. Selain itu, dengan adanya pergeseran frekuensi Doppler mengakibatkan semakin sulitnya menjaga level Bit Error Rate (BER) kurang dari 0,001. Mengubah threshold channel gain pada modulasi adaptif adalah salah satu metode yang dapat diterapkan untuk menjaga level performansi tanpa mengorbankan nilai Signal to Noise Ratio (SNR). Sayangnya threshold yang memberikan SNR optimal belum diketahui. Pada penelitian ini digunakan algoritma random forest regression untuk mencari nilai threshold channel gain demi didapatkannya nilai SNR terbaik. Dari hasil prediksi dengan jumlah estimator sebanyak 7, didapatkan threshold 0.1 dan 0.3 hanya membutuhkan SNR sebesar 25.59 dB untuk menjaga BER di level< 0.001.Kata kunci: Modulasi Adaptif, Pergeseran Doppler, Random Forest Regression ABSTRACTThe condition of the moving vehicles in the Vehicle-to-Vehicle (V2V) communication system leads to fluctuating received signal power. In addition, the Doppler shift increases the difficulty to maintain the Bit Error Rate (BER) less than 0.001. Changing the channel gain threshold in adaptive modulation is one method that can be applied to maintain the performance level without sacrificing the Signal to Noise Ratio (SNR) value. Unfortunately, the threshold that provides the optimal SNR is not yet known. In this research, a random forest regression algorithm is used to determine the channel gain threshold in order to obtain the best SNR value. Based on the prediction results the number of estimators of 7, it is obtained that the thresholds of 0.1 and 0.3 only require an SNR of 25.59 dB to keep the BER at the level < 0.001.Keywords: Adaptive Modulation, Doppler Shift, Random Forest Regression

Published: July 2022

ABSTRAKElektroensefalografi (EEG) adalah teknik perekaman yang merekam aktivitas elektrik pada otak menggunakan elektroda yang ditempelkan pada kulit kepala. Artefak elektrookulografi (EOG) adalah salah satu artefak yang kerap muncul pada perekaman EEG dikarenakan pergerakan mata dan menyebabkan sinyal EEG berubah bentuk. Untuk membersihkan EEG, artefak perlu dibuang dengan tetap menjaga informasi penting dari EEG. Pada penelitian ini kami mendeteksi artefak EOG menggunakan Independent Component Analysis (ICA) dan deteksi puncak, dan untuk rekonstruksi sinyal EEG kami menggunakan Denoising Autoencoder (DAE). Pada penelitian ini kami meneliti model DAE apakah dapat merekonstruksi sinyal EEG dari artefak EOG. Metode pendeteksian artefak mendapatkan 85% sensitivitas dan 83% Positive Predictive Value (PPV) pada dataset sekunder dan 82% sensitivitas pada dataset primer. Model DAE dilatih dengan validasi silang 10 lipat dan mendapatkan rerata mean squared error (MSE) 0,007±0,008. Penelitian ini membuktikan kemampuan DAE untuk merekonstruksi sinyal EEG denganmasukan segmen sinyal EEG terkontaminasi artefak EOG.Kata kunci: EEG, Artefak EOG, Denoising Autoencoder ABSTRACTThe Electroencephalography (EEG) is a recording technique to record electrical activity on the brain using electrodes attached to the head scalp. Electrooculography (EOG) is one of the artifacts that are prone to appear on EEG due to eye movement and cause EEG signals to deform. To fix the EEG signal, we need to remove artifacts while conserving EEG information. In this research, we detect EOG artifactual signal using Independent Component Analysis (ICA) and peak detection and used a generative model Denoising Autoencoder (DAE) to reconstruct clean EEG by using EEG artifact-corrupted signal. Our artifact detection method scores 85% sensitivity and 83% Positive Predictive Value on the secondary dataset and 82% sensitivity on the primary dataset. We train the DAE model with 10-fold cross-validation and got 0.007 ± 0.008 Mean Squared Error (MSE). We demonstrated DAE on its ability to generate a clean EEG segment by feeding it contaminated EEG segment.Keywords: EEG, Eye movement artifact, Denoising Autoencoder

Published: July 2022

Conventional techniques of improving the bond properties of virgin Polyethylene Terephthalate Fibres reduce the mechanical strength of the fibres, are labour intensive, and present environmental hazards in the case of chemical treatment. This study introduces a new way of improving the bond properties of fibres obtained from waste Polyethylene Terephthalate bottles by coating the surface of the fibres with a thin layer of sand to counteract the above-mentioned shortcomings. Their performance was compared to that of embossed, serrated, and straight fibres and a control mix without fibres. Workability, compressive strength, tensile and flexural strength were used to assess this performance. Constant fibre length, width, and content were maintained for this exercise. Compared to the other fibres, sand-coated fibres gave the highest increment in tensile and flexural strength of 9.49% and 11.61% compared to the control mix, even though concrete’s workability and compressive strength were decreased. Furthermore, the optimization of the fibre length and content for the sand-coated fibres was carried out. The 75 mm long fibres showed the highest improvement in tensile strength of 13.76% and flexural strength of 12.49% compared to other fibre lengths. The optimum percentage of fibres was 1.25% with a 15.49% and 17.26% increment in tensile and flexural strengths, respectively. Doi: 10.28991/CEJ-2022-08-06-03 Full Text: PDF
Land Procurement for Public Interest Against Destroyed Land: Natural Events and Legal Certaint

Published: July 2022

Based on a case study on the construction of the Semarang-Demak Toll Road, this study aims to investigate and investigate land acquisition for the public interest for land that has been destroyed as a result of natural events and its legal certainty. The research method used is socio-legal with primary data in identification, field measurements, and other supporting data. Semarang-Demak Toll Road property acquisition demonstrated tidal inundation on the north shore. Subsidence exacerbates Semarang's flooding. On flooded land, sea dikes and retention ponds prevent tidal floods. If just for transportation, the Semarang-Demak Toll Road can be built in flood-free areas or over the sea, like Bali's Mandra Toll Road. Land acquisition concerns delayed the Semarang-Demak Toll Road. Lack of land limitations has delayed land purchases. In the Semarang-Demak Toll Road land acquisition, destroyed land is not a problem under Indonesian law. 2021's Regulation 18 defines destroyed land. Destroyed land will drive people to take better care of their land and be more concerned about global warming or land subsidence. The state honors the landowner's emotional connection by paying for spiritual care. Doi: 10.28991/CEJ-2022-08-06-06 Full Text: PDF

Call for Social Justice in Arvind Adiga’s The White Tiger
Authors: Baral Pawan 
Published: July 2022

The paper aims at examining Arvind Adiga’s The White Tiger in the light of social justice under the then political establishments of India where globalization has almost paralyzed the heart of democracy itself. Adiga deploys many techniques to intensify his arguments, the amalgamation of which has a magic-like emphatic effect in his expression of bitterness. He mixes up lightheartedness, extremity of injustice, IT age version of epistolary mode, and playful colloquial language in such a way it hypnotizes the readers from suspecting frequent exaggerations of situations and lack of authenticity in his depiction. The paper ultimately argues that Adiga calls for a just society through the novel. He feels ashamed of the contemporary democratic practice which may produce many, many Balrams unless the system of government restores social justice in time. With strong conviction on democracy as a good system of government, Adiga leaves a note of optimism amid confusion and hopelessness. As a staunch democrat, he has two ways of reformation in the present practice in the final chapter: the first for the short-run and the other for the long-run. Ultimately, Adiga envisions that enlightened citizenry can contribute to the free and fair practice of democracy and of globalization in the long run. The study adopts qualitative based literary mode of research. It draws primary data through close reading of the text in question. Then the firsthand data from the text will be analyzed drawing and departing the ideas of critics and thinkers of social justice, globalization and democracy as well as.
Soil Erosion Status of Nepal
Authors: Gurung Sher Bahadur 
Published: July 2022

Soil erosion is one of the problems in Nepal because about 73 percent of the land surface is mountainous and still tectonically active where 60.43 percent people involved in agricultural activities. The paper assesses the soil erosion status based on ecological region and watershed boundary with population density. The ecological region determined based on elevation and the watershed boundary of Nepal was generated using the Advanced Spaceborne Thermal Emission and Reflection Radiometer–ASTER, 30m resolution Digital Elevation Model (DEM) of NASA's Earth Observing System (EOS) on May 14, 2010. The DEM data was processed using remote sensing technique then hydrological analysis conducted using remote sensing and geographic information system to delineate the watershed boundary. The study generates 19 watersheds based on available soil erosion data. The soil erosion rate of ecological zone and watershed are assessed with population data of Nepal from central bureau of statistic, 2011. There is below 50 people per square kilometer watersheds have average soil erosion rate (about 20 t ha-1/ y-1) and 100 to 500 people per square kilometer watersheds have high soil erosion rate ranges from 27 to 102 t ha-1/ y-1 . These scenarios partial follow the theory of Himalayan degradation. So that there is still environmental degradation is observed and it is needed in detail field based study of Himalaya degradation
