Authors: Ardiansyah Muhaimin
Published: December 2024

As a country that continues to develop, the construction of high-rise buildings is inevitable, given the many capacities and functions of these buildings. However, considering that Indonesia is located between 4 main active plates of the world, so it is an area that is prone to earthquakes. As a result of this earthquake, it is necessary to design a structure that is stronger and more rigid in order to be able to withstand earthquake vibrations for a long time as much as possible.This research consists of designing the superstructure of a building in the seismic zone D by comparing the value of the drift ratio, displacement,  and the amount of reinforcement towards variation structure model that occurs due to the response spectrum of earthquake load. The analytical method used is the response spectrum analysis method modelled on 3 building structure models.Based on the result of the design analysis carried out on all models, the dimension for beam with all models are 35 x 45 cm and 25 x 35, the column dimensions are 50 x 50 cm, the floor slab thickness is 125 mm and the shear wall thickness is 30 cm. The results for the model that has shear walls, decreased in the amount of reinforcement up to 14% in the column and 10% in the beam and decreased to 3% in the column and 6% in the beam for the bending moment. For the maximum drift ratio value, which is 10.26% in the x-direction of the shear wall structure model 2 and 6.81% in the y-direction shear wall structure model 3 and the smallest displacement value due to the load response spectrum on the placement of the shear wall is model 3, then the recommended model for structural planning in the seismic zone D is model 3.Keywords : momen frame system, dual system, seismic zone D, reinforcement, drift ratio, displacement

One of the methods used in controlling project time and costs is the earned value concept method. Earned value is a concept of calculating the cost budget by the work that has been completed. Where performance is measured is work completed at a certain time, which is assessed based on the amount of budget available on the project. For this reason, it can later be known the relationship between the physical progress achieved and the budget that has been spent.In this study, the object of research used was the Tanipah Village Environmental Road Improvement project, Mandastana District, and used existing data, namely general project data, contract value, schedule, and weekly reports. This study uses project performance analysis based on time and cost using the Earned Value Management method.The results of the data analysis obtained were that there was a delay in project work in week 1 and week 2, but scheduling performance improved so that in the following week there were no more delays and the project was completed on time. In terms of costs, in week 1 to week 7 the costs incurred exceeded the budget but in week 8 cost performance improved and in the last week the profit obtained amounted to Rp. 40,207,776. Keywords: Earned Value, Cost, Time

Authors: Ramadhani M Aulia , Novitasari Novitasari
Published: December 2024

The Liang Anggang Protection Forest is an area formed from peat soil. Peat soils have a role to play in conserving water resources, reducing flooding, preventing seawater seepage, and so on. Damage to the water system in peat soils is often caused by individual activities that are not well controlled. This is thought to have resulted in the depletion of water in peat soils, causing the soil to become dry and flammable in the dry season. The purpose of this research is to examine the rate of water infiltration in Liang Anggang Protected Forest Block 1. In this study, the method used in analyzing the infiltration rate was the Horton method by measuring the infiltration rate using a double-ring infiltrometer (turf-tec infiltrometer). According to the study's findings, the average decrease in infiltration rate of test 1 on bare or low-density land is 12.4 cm/hour, medium-density land is 2.7 cm/hour, very dense, closed, or forested land is 3.6 cm/hour, and test 2 on barren land is 2.4 cm/hour, medium density land is 2.7 cm/hour, and very dense, closed, or forested land is 4.7 cm/hour. Keywords:      Double ring infiltrometer, Infiltration Rate, Horton Method, Liang Anggang Protection Forest

Published: December 2024

The Pebaungan River is one of the river sections in Pabaungan Hilir, Candi Laras Selatan District, Tapin Regency, South Kalimantan. In this river, there is a retaining wall with a slope condition. This planning is carried out by collecting the necessary data, followed by an analysis of the characteristics of the study soil. The value of the safety factor for the current conditions is then calculated by simulating the stability of the slope using the geoslope. After that, the pileslab design is calculated by taking into account the loading, reinforcement, and foundation calculations. After the pileslab was fixed, the slope stability analysis modeling was again carried out to determine the safety factor.According to the analysis's findings, the study soil's characteristics for hard soil were at a depth of 40 meters, and the safety factor for slope stability under the current circumstances was 0.947, which was not safe. The pileslab calculation takes into account standard loading and reinforcement, as well as the foundation design using a 30x30 square pile and accounting for bearing capacity, the lateral force of the pile, and settlement. After that, modeling was carried out to get the value of the overall slope safety factor after the pileslab was installed, which came out to be 1.515. Keywords: Pileslab, slope stability, settlement, bearing capacity

Published: December 2024

State border areas are areas that have strategic positions. Because of this weakness becomes a strategic issue in the border area as the front porch of the country. The border area of Indonesia as the external face of the country is impressed if its management is more predicated on a safety approach (safety belt approach). Villages in Indonesia are still areas that are quite difficult to untangle; it is often narrated that he is lagging in development affairs so that social, economic, infrastructure and other developments seem to be neglected. The Village Sustainable Development Goals are a development concept that places more emphasis on environmentally friendly development and protects the culture and interests of the local community. This study aims to see how the goals of sustainable development (SDGs) are in the border villages of the Rokan Hilir district. This study uses a qualitative approach. Data collection was carried out through in-depth interviews, observation, and interactive photography techniques to gain an in-depth understanding of the research problem. Informants were determined by purposive sampling technique. After the data has been collected, it is analyzed using an analytical approach using the N-Vivo 12 to explain, present and place the data so that conclusions can be drawn and drawn. To achieve sustainability, cooperation is needed in the 3 dimensions of the SDGs which balances development on the economic, social, and environmental dimensions. The results of the study show that the Village Sustainable Development Goals, especially Teluk Pulai Village in the border area of Rokan Hilir District, have not been realized based on indicators of fulfilling sustainability. Apart from that, it can also be seen from the SDGs achievement targets that were not achieved which ultimately had an impact on the Village SDGs Score of 35.96 and the Developing Village Index (IDM) with a Developing status. The SDGs goals in the border area have not been realized, including a lack of village development programs where the planned programs only focus on meeting the needs of the village community so the SDGs Village goals needed by the community are not planned.

Published: December 2024

Penelitian ini memiliki tujuan untuk mengeksplorasi dampak variasi arus pengelasan GMAW terhadap distorsi dan kekerasan pada material baja ST37 setelah dipanaskan pada suhu 400˚C. Hasil penelitian mengenai variasi arus dan perlakuan post heating pada suhu 400°C di daerah HAZ dan pada area Weld Metal menunjukkan perbedaan yang signifikan dalam nilai kekerasan. Perbedaan ini dipengaruhi oleh variasi arus yang diberikan; semakin tinggi arusnya, semakin besar pula pelunakan logam yang terjadi. Sebagai contoh, pada arus 100 A, nilai kekerasan tercatat sebesar 65 HRB, sedangkan pada arus 120 A, nilai tersebut turun menjadi 56,4 HRB. Di bagian Weld Metal, nilai kekerasan tertinggi terlihat pada arus 80 A (59,8 HRB), dan nilai terendah terdapat pada arus 120 A (51,1 HRB). Dari ketiga perbedaan suhu yang diberikan kepada spesimen dengan arus yang berbeda, yaitu 80 A, 100 A, dan 120 A, memiliki nilai distorsi rata-rata tertinggi pada arus 80 A (1,17 mm), diikuti oleh arus 100 A (0,85 mm), dan terendah pada arus 120 A (0,68 mm). Hasil penelitian uji distorsi ini menunjukkan bahwa perlakuan post heating sangat berpengaruh terhadap nilai distorsi pada spesimen tersebut. This study seeks to investigate the impact of varying GMAW welding currents on distortion and hardness in ST37 steel material post-heating at 400˚C. The research findings on the variations in current and post-heating treatment at 400°C in both the HAZ (Heat Affected Zone) and Weld Metal areas reveal significant differences in hardness values. These differences are attributed to variations in the current supplied; the higher the current, the greater the metal melting (softening) observed. For instance, at 100 A, the hardness value is recorded at 65 HRB, while at 120 A, it decreases to 56.4 HRB. In the Weld Metal section, the highest hardness value is observed at 80 A (59.8 HRB), and the lowest is at 120 A (51.1 HRB). Among the three different current levels (80 A, 100 A, and 120 A) applied to spesimens, the average distortion value is highest at 80 A (1.17 mm), followed by 100 A (0.85 mm), and lowest at 120 A (0.68 mm). These results underscore the significant impact of post-heating treatment on the distortion of the spesimen.

Authors: Mujiarto Sigit , Priyanto Joko , Purnomo Sigit Joko
Published: December 2024

Kebutuhan energi Indonesia saat ini sebagian besar masih bertumpu pada bahan bakar fosil, persediaan bahan bakar tersebut semakin berkurang seiring berjalannya waktu. Ketergantungan terhadap bahan bakar fosil ini menjadi masalah besar dan perlu solusi yang mendesak. Salah satu langkah yang perlu diambil adalah memanfaatkan bioetanol berbahan dasar singkong sebagai alternatif penggantinya. Indonesia sebagai salah satu negara penghasil singkong terbanyak didunia, masih belum bisa memanfaatan sumber daya tersebut sebagai salah satu energi terbarukan. Pada penelitian ini dilakukan pembuatan bioetanol dengan bahan baku singkong (Manihot Utilisima). Penelitian ini menggunakan metode eksperimen pengaruh konsentrasi ragi (1,5%, 2%, 2,5%) dan proses dehidrasi zeolite dalam pembuatan bioetanol singkong untuk mengetahui karakteristik bioetanol. Dari hasil penelitian didapatkan karakteristik bioetanol terbaik pada variasi ragi 2,5% dengan nilai kadar air sebesar 84%, nilai densitas sebesar 0,8136 g/ml, dan nilai Viskositas sebesar 0,07973 dPa.s. Hasil ini mempunyai nilai mirip bahan bakar pertalite namun kadar air dan densitasnya masih lebih tinggi. Diharapkan kedepannya menjadi database untuk penelitian bahan bakar bioethanol berikutnya. Indonesia's current energy needs are still largely based on fossil fuels, the supply of these fuels is decreasing over time. This dependence on fossil fuels is a big problem and needs an urgent solution. One step that needs to be taken is to use bioethanol made from cassava as an alternative. Indonesia, as one of the largest cassava producing countries in the world, is still unable to utilize this resource as a form of renewable energy. In this research, bioethanol was produced using cassava as raw material (Manihot Utilisima). This research uses experimental methods on the influence of yeast concentration (1.5%, 2%, 2.5%) and the zeolite dehydration process in making cassava bioethanol to determine the characteristics of bioethanol. From the research results, it was found that the best bioethanol characteristics were the 2.5% yeast variation with a water content value of 84%, a density value of 0.8136 g/ml, and a viscosity value of 0.07973 dPa.s. This result has a value similar to pertalite fuel but the water content and density are still higher. It is hoped that in the future it will become a database for further bioethanol fuel research.

Published: December 2024

Background: Professionalism has been identified as a key competency for physicians to conduct, effective and ethical practice. The current competency-based medical education curriculum lays great emphasis on the development of attitude, ethics, and communication (AETCOM) among medical students which is embedded in the core concepts of professionalism. Comprehending these concepts early in the course of medical training is especially important as such a change may lead to reducing future incidents of professional misconduct. However, teaching this complex topic to undergraduate students through routine didactic lectures alone is challenging.

Methods: To address this, we divided the batch of second-year MBBS students into 5 random groups and assigned 1 case scenario for role play to each group with sub-questions for discussion and reflection. After a short introductory lecture on professionalism, each group presented their role-play and discussed the sub-questions. Assessment for the improvement in knowledge was done using pre and post-test multiple choice questions.

Results: Our findings show a statistically significant improvement in the mean (± Standard Deviation) scores for post-test (16.76±3.00) vs the pre-test (11.56±2.81) (p< 0.0001). Participant feedback was overwhelmingly positive based on the 5-point Likert scale.

Conclusion: This shows that an interactive and engaging model, such as relevant case scenarios and role-play with reflection, along with assessment and feedback, could be effective for medical students, in learning the complex topic of professionalism.

It must be argued that the rising number of IoT devices has latest features they got cybersecurity threats and further robust techniques to detect and prevent these threats are needed. This paper aims to propose a novel solution to IoT cybersecurity by using the BoTNeTIoT-L01 dataset and advanced artificial neural networks. The work enhances the classification and categorization of IoT cyber threats using models such as Decision Trees, Logistic regression, LightGBM, and Deep learning. Data pre-processing is been done comprehensively by feature selection and by encoding. A specific enhancement from previous models is the further enhancement of the model performance through the inclusion of T-scores, Leaky ReLU, and Ordinal Encoder. LightGBM and Decision Trees showed superiority in the basic fields of measure such as F1 score, precision, and recall, and the study achieved high accuracy and a high recall rate in threat detection. Specifically, the proposed method achieved an accuracy of 98.76 percent and a loss of 0.034 percent, demonstrating its effectiveness. Comparing LightGBM and Decision Trees with deep learning models, it was found that while both sets of models offered the right balance of testing accuracy with computational amenities, the deep learning models were superior in terms of complexity and pattern discovery. The present study proves that using machine learning algorithms can significantly enhance IoT security; however, the information suggests that updates and changes need to be made constantly and frequently to address the emerging risks.

Published: December 2024

With the rise of computers and their importance in various fields, traditional electric meters in Pakistan have been replaced by digital electric meters. These digital meters are more accurate and easier to read as they display readings using Seven-Segment Digits. Currently, for billing purposes, human meter readers manually capture images of these meters using cameras or smartphones, and the readings are then recorded manually. This process is time-consuming and prone to errors due to human involvement.Automating the reading of meter images can significantly improve the accuracy and efficiency of the billing process. However, this task is challenging because the captured images can vary in quality, scale, orientation, lighting conditions, and other factors.To address these challenges, we experimented with different machine learning and deep learning models to automatically recognize meter readings from captured images. Five models were trained and evaluated: K-Nearest Neighbors (KNN), Decision Tree, Support Vector Machine (SVM), Random Forest, and Convolutional Neural Network (CNN). These models were tested on real meter data for digit recognition, achieving an accuracy of up to 98%. This promising result demonstrates the potential for fully automating the meter reading process in the future.

Customer attrition is especially an issue in industries such as retail, banking, and telecommunications where customer acquisition costs are significantly higher than the costs of retaining repeat customers. The customer lack of interest is now predictable through machine learning models, and deep learning has become instrumental in early intervention for retention. In order to assess the quality of churn prediction, the study tests six basic machine learning techniques: random forest, logistic regression, and the k-nearest neighbors method, as well as four deep learning techniques: long short term memory (LSTM), bidirectional LSTM, convolutional neural networks (CNN), and artificial neural networks (ANN). The performance of the model is then assessed via the evaluation matrices, including the accuracy, precision, recall, and F1-score from the customer's behavioral data after feature extraction from large datasets. The study reveals that DL models offer improved handling of the churn and non-churn customer classification and Random Forest as well as other ML models comparable accuracy. This research can conclude that LSTM and ANN models outshine in actual-world churn prediction circumstances, especially when long-term consumer behavior evaluation is required. To enhance the current outcomes of a given prediction model, this research focuses on data preprocessing and the utilization of bootstrapping, feature extraction, and the combination of multiple models. The implications of the study provide specific practical recommendations for firms to effectively manage customer churn and increase customer retention by employing data-dealing techniques.
Predictive Modeling of Cerebral Strokes: An ADASYN-RF Approach for Imbalanced Data
Authors: Aish Muhammad Abdullah
Published: December 2024

Cerebral stroke is a condition that occurs when blood flow to the brain suddenly stops, and the cells in the brain subsequently die due to lack of oxygen and nutrients. A stroke is associated with risk factors that are mainly linked with lifestyles today, including metabolic syndromes such as high "glucose level, heart diseases, obesity, and diabetes".Current study develops a stroke prediction using the machine learning algorithms: "Logistic Regression (LR), Random Forest (RF), and K-Nearest Neighbors (KNN)". The dataset required for the above study was sourced from the Harvard Dataverse Repository. The "clinical, physiological, behavioral, demographic, and historical data" are included in thisdataset. In this respect, the imbalance of classes would be handled by employing over-sampling techniques, including "SMOTE, ADASYN, and ROSE". This paper proposes a new hybrid machine learning model by combining ADASYN with Random Forest, known as ADASYN-RF, where ADASYN will resample the imbalanced dataset, then Random Forestis applied on the resampled data. Besides, other machine learning models and oversampling techniques are employed for the comparison. Surprisingly, the ADASYN-RF model is able to achieve the highest detection accuracy of 99% mentioned herein, proving its efficiency in stroke prediction. This method thus provides an inexpensive and precise tool for clinical diagnosis of stroke.
