Abstract

Slope failure can occur even though slope design and reinforcement have been carried out. However, before it completely collapses, there are often signs from the slope. These signs should be carefully observed through slope monitoring or surveillance activities to provide advance warnings regarding the development of slope instability, allowing mitigation measures to be implemented to reduce or avoid the impacts of instability, as well as to predict the timing of landslides using Inverse Velocity. This study was conducted at the PIT of PT Fajar Sakti Prima in East Kalimantan Province. Observations were carried out over 39 days to obtain deformation behavior, velocity values for mitigation actions, and inverse velocity values to predict the timing of landslides. In this observation, the deformation behavior values at PM 01, PM 02, and PM 03 were initially linear, then exhibited progressive behavior on November 7-8, 2024. The predicted landslide timing from this observation was November 20-21, 2024. Based on velocity values correlated with the TARP, critical categories were obtained at 7.40 - 9.86 cm/day and very critical at >26.17 cm/day

Abstract

This study aims to analyze the effect of variations in CVT spring constants (4.94 N/mm, 6.09 N/mm, and 7.38 N/mm) and roller masses (10 g, 13 g, and 15 g) on torque, power, and specific fuel consumption (SFC) of a 110 cc matic motorcycle. Testing was conducted using a dynotest to measure torque and power, and a measuring glass for fuel consumption at engine speeds of 5000–9000 RPM. Results showed a maximum power of 7.93 HP at 7000 RPM with a 10 g roller and 4.94 N/mm spring, the highest torque of 8.56 Nm at 6000 RPM with a 13 g roller and 4.94 N/mm spring, and the lowest SFC of 0.0689 kg/kWh at 9000 RPM with a 10 g roller and 6.09 N/mm spring. Two-Way ANOVA analysis indicated that all factors and their interactions significantly influenced engine performance (p-value < 0.05), with the statistical model showing an R-squared above 97%. The combination of a light roller and medium spring provided the best fuel efficiency, while heavier rollers were more optimal for torque at mid-range RPMs.

Abstract

The problem of plastic waste has developed into an urgent global environmental crisis, due to the nature of plastic that is difficult to decompose and can persist in the environment for hundreds of years. This study explores pyrolysis as a promising oxygen-free thermal conversion technology to overcome plastic waste by converting it into valuable products such as oil, gas, and char. The main focus of the study is the use of zeolite catalysts in the pyrolysis of polyethylene plastic waste from household waste, with a total mass of 1.5 kg of plastic waste and 200 grams of zeolite catalyst. The catalyst used, natural zeolite from Klaten, Central Java, was heated at a temperature of ±200°C before being used in a pyrolysis reactor at an operating temperature of 450°C for ±4 hours. The results showed that the use of zeolite catalysts reduced the percentage of liquid and solid products, but increased the percentage of gas products. In addition, the use of catalysts tended to reduce the content of medium fractions (C11-C22) and paraffin fractions, while increasing the light fractions (C4-C11) and olefin fractions. These findings indicate the potential of pyrolysis as a sustainable solution to the plastic waste problem with positive impacts on the environment and economy.

Abstract

Advances in information technology have had a major impact on the education sector, including at the Early Childhood Education (PAUD) level. To improve the quality of education services, PAUD institutions are required to implement a more sophisticated, accurate, and efficient management system through the use of an integrated information system. This study raises various obstacles faced by PAUD KB Tsamrotul Hikmah, especially in terms of recording teacher attendance, submitting leave, and managing finances that still use manual methods. This conventional system has been shown to reduce work effectiveness, increase the possibility of errors, and weaken the transparency and accountability aspects of the institution. To overcome these problems, an information system was developed to support automated administration processes and more systematic data management. The findings of this study indicate that digitalization of administration can improve work efficiency and data accuracy, as well as build public trust in the institution. Therefore, the implementation of an integrated information system is considered a strategic step in creating more professional, open, and sustainable PAUD management.

Abstract

This research iss motivated by the problem of the lack of digital learning facilities that can be flexibly accessed by students and theachers at SMP Djama'atul Ichwan Surakarta, so that interaction in the theaching and learning proces is limited. The theories applied in this study include the concept of E-Learning as a distance learning method rooted in information technology, web-based system development, and an interactive technology integration approach to increase effectiveness and engagement in learning. The method used is the Waterfall model system development life cycle (SDLC), which includes the stages of needs analysis, system design, implementation with PHP and MySQL using the CodeIgniter framework, and function testing. The research findings show that the designed web-based E-Learning system successfully provides features for managing student and teacher data, distributing teaching materials, scheduling lessons, giving assignments, and interaction through discussion forums. This system is considered capable of supporting a more organized and interactive online education process.The implementation of this systemis expected to a long-term solution to overcome the limitations of traditional learning methods and become a foundation for the development of digital learning platforms in the futur.

Abstract

Sewing workers at CV Cahaya Setia Mulia Abadi perform static and repetitive tasks, such as prolonged sitting in a bent posture and continuous sewing movements. These conditions lead to various physical complaints, including back pain (78%), lower neck pain (75%), upper neck discomfort (73%), as well as shoulder fatigue, wrist tingling, and lower back stiffness. This research is conducted to evaluate the potential risk of musculoskeletal disorders (MSDs) through the application of the Rapid Entire Body Assessment (REBA) method, determine the body parts most frequently affected using the Nordic Body Map (NBM) questionnaire, and develop posture correction strategies based on anthropometric measurements.The REBA results indicate that most sewing activities fall into the medium-risk category (score 5–7), with some in the high-risk category (score 8). The intervention involved adjusting chair dimensions based on anthropometry, and adding seat cushions and backrests. After the simulation of improvements, the REBA score decreased to 2, placing it in the low-risk category. These findings demonstrate that ergonomic chair design and proper working posture significantly reduce physical strain, increase comfort, and help maintain worker productivity. This study offers practical recommendations for creating a healthier and safer work environment in the manufacturing sector.

Abstract

Alumunium AA1100 is widely used in flat plate products such as heat exchanger fins and lightweight structural panels, yet it’s welding process still requires optimization. This study aims to determine the effect of tool traverse speed and backing plate preheating temperature on the bending strength of AA1100 joints produced by Friction Stir Welding (FSW). Experiments were conducted at three levels of each factor with three replications per combination: traverse speeds of 10 mm/min, 20 mm/min, 30 mm/min, and preheating temperatures of 200 °C, 250 °C, 300 °C. Results showed the travers speed, preheating temperature, and their interaction all had significant effects on bending strength (P-Value < 0,05). The optimal combination 30 mm/min traverse speed and 200 °C preheating yielded a bending strength of 238,95 Mpa. The regression model’s coefficient of determination was 97,16%, indicating an exellent fit. Thus, selecting the right FSW parameters can significanly enhancejoint quality.

Abstract

This study aims to analyze the effect of electrical voltage and flywheel mass on the kinetic energy produced by the starter motor, as well as to evaluate the geometric shape of the flywheel. The kinetic energy in the flywheel is influenced by the moment of inertia and angular velocity produced by the starter motor. The study was conducted exprerimentally using a quatitative approach, with variations in voltage (11V-14V) and flywheel mass (0.9-1.2 kg), and analyzed using a Two-Way ANOVA Faktorial test. The results show that both voltage and flywheel mass significantly affect kinetic energy, with increased voltage linearly increasing RPM and energy, and a larger mass increasing the moment of inertia. The interaction between the two is synergistic, with the combination of 1.2 kg and 14V voltage yielding the highest energy (4.0 Joules), and an R-squared value of 97.65 % indicating the model is highly accurate. These findings support the development of efficient mechanical energi storage system and optimal flywheel design.
