Abstract

Currently, MIS Guppi Sawang Lebar has a Computer Laboratory but the facility cannot be utilized properly and MIS Guppi Sawang Lebar wants to hold exams that utilize computers to simulate exams conducted through computers held by the government. However, MIS Guppi Sawang Lebar has several limitations, such as the absence of supporting software to conduct exams via computer. So a Computer Based Test (CBT) System will be designed and built at MIS Guppi Sawang Lebar. The research method applied is the development of web-based information systems. This development uses various technologies, including HTML, PHP, Bootstrap, and Laravel as a framework, as well as MySQL as database management. The result of the development of this Computer Based Test (CBT) System is that users have access to complete features. The admin page allows to add users, create exam lists, assign sessions, and view score graphs. On the other hand, the user page allows to view the exam session schedule and information about the exam to be conducted. With the existence of the system, it is expected to make it easier for MIS Guppi Sawang Lebar in the exam process that uses computers.

Abstract

The industrial revolution 4.0 has encouraged the development of automation systems, including the 6 DOF robotic arm to enhance industrial production efficiency and effectiveness. This study aims to redesign a 6 DOF robotic arm based on benchmarking with Fanuc M-20iA and ABB IRB 2600 models using AutoDesk Inventor 2024. The method employed is benchmarking by comparing designs and specifications, followed by redesigning the Bill of Materials (BoM), Operation Process Chart (OPC), and assembly chart. The results show modifications such as redesigning the base into a square shape, adding rubber strips to the gripper, creating a separate panel for the motor driver and controller, and replacing the electromagnetic gripper with a mechanical one. The final design produces a simpler robotic arm with a production cost (HPP) of Rp105,554,924.00, which is more economical compared to similar products. The newly designed gripper is recommended for vertical object handling and positioning. Thus, the design successfully reduces maintenance costs, enhances precision, and maintains optimal performance for industrial applications.

Abstract

The Way Pagar Alam Bridge in Tanggamus Regency experienced failure at one of its widened abutments due to a combination of weak geotechnical conditions, rainfall infiltration, and riverbank erosion. This study aims to assess the structural and geotechnical conditions of the bridge and develop an effective reinforcement design. The methodology includes visual inspection, laboratory testing of soil, structural vibration monitoring, and slope stability analysis using limit equilibrium-based software. Vibration tests indicate that the bridge superstructure remains stiff, with vertical deflection well below the allowable limit. Subsurface investigations revealed the presence of expansive clay with low bearing capacity in shallow layers. Stability analysis shows that a combined reinforcement system—comprising a retaining wall, gabion protection, and mini piles—can enhance the slope safety factor to 1.99 (static) and 1.73 (dynamic), meeting applicable engineering standards. The proposed design is considered effective and applicable for bridge rehabilitation in tropical regions with soft subgrade conditions.

Abstract

The selection of a suitable classification model is important in text-based sentiment analysis, especially in conditions of unbalanced data distribution. Naive Bayes and Support Vector Machine (SVM) are two algorithms that are often used in classification, but the comparison of their performance on unbalanced data still needs to be further reviewed. This study aims to compare the performance of the two algorithms in classifying public sentiment towards the Indonesia Smart Card (KIP) Lecture Program. The implementation of the KIP Lecture Program still faces challenges in the accuracy of aid distribution. This situation raises discussions and various controversies among the public, especially on the X platform. The data used were 1,644 tweets, with a distribution of negative sentiment of 1,392 tweets and positive tweets of 252. To overcome the imbalance of data class distribution, the Synthetic Minority Oversampling Technique (SMOTE) method is used. Based on the evaluation results, before SMOTE was applied, SVM obtained 92% accuracy and 91% precision, 77% recall, while Naive Bayes obtained 79% accuracy, 68% precision, and 78% recall. After the application of SMOTE, SVM performance significantly improved with accuracy, precision, and recall reaching 99%, while Naive Bayes improved to 95% on all metrics. These results show that although SVM excels in higher accuracy, Naive Bayes shows a more stable performance on the data neither after nor after the balancing process is performed.

Abstract

Micro hydro power plant (PLTMH) is a small-scale power plant that uses water in small discharges as its driving source. Water that can be utilized in PLTMH technology can come from irrigation channels, rivers or natural waterfalls. In general, PLTMH has three main components, namely water, water turbines, and generators. The purpose of this study is to analyze the effect of variations in water discharge on the performance of horizontal francis turbines in the Aek Sigeaon Micro Hydro Power Plant (PLTMH) system. The main focus of this study is to observe changes in input power, output power, and turbine efficiency as a result of variations in water discharge that occur in the field. Data collection was carried out using a SCADA monitoring system to obtain operational parameters in real time such as water discharge, pressure, current, and voltage. The results showed that an increase in water discharge generally caused an increase in input and output power, but was not always directly proportional to turbine efficiency. The highest turbine efficiency of 77.8% was obtained at a water discharge of 3.48 m³/s, while the lowest efficiency of 54.65% occurred at a water discharge of 6.01 m³/s. This shows that the horizontal Francis turbine works more efficiently at low to medium discharge.

Abstract

Palu City is one of the areas with a high level of disaster risk, particularly earthquakes, tsunamis, and liquefaction. The disaster on September 28, 2018, revealed that mosques, besides functioning as places of worship, also play a crucial role in social life and serve as emergency shelters. This study aims to examine the potential of mosques as disaster mitigation centers by assessing community emotional attachment, accessibility, supporting facilities, as well as building design and safety. A mixed-method approach was employed through in-depth interviews and Likert-scale surveys with six respondents who were survivors sheltered in the Baiturrahim Grand Mosque, Palu. The findings indicate that the community’s social and emotional attachment to mosques is very strong, yet significant weaknesses remain in emergency facilities and evacuation signage. Meanwhile, the mosque structure is perceived as relatively strong and ready to serve as a temporary shelter. These results highlight the importance of strengthening the technical capacity of mosques through the provision of emergency facilities, basic logistics, and clear information systems, so that their role as disaster mitigation centers can be more effective in the future.
