Abstract

Contingency costs are an important part of construction to achieve successful project management. In determining contingency costs, practitioners have used a very subjective approach. This study discussed the determination of the contingency cost of high-rise buildings in six research object projects, based on the results of risk evaluation. The risk evaluation used in this paper is based on the risks in the construction phase. The method used to know the relationship between risk and contingency costs is simple linear regression with tools. The results of this study indicate that the greater the level of risk, the greater the contingency costs incurred by the project. the risk level contributed 71.6% to the contingency cost, while the rest was influenced by other factors. The equation formed is, that if the risk increases by 1 unit, the total contingency cost will increase by 0.0916 units.

Abstract

Cooperative digitalization makes it transparent, accountable, easy, and fast, allowing cooperatives to address socio-economic needs effectively. The case study of KSPPS TAMZIS shows that IT governance is necessary to ensure that the use of cooperative technology can optimally support organizational goals. The COBIT 2019 framework was used in this research. The research method, Governance System Design Workflow, involves understanding objectives, strategies, determining the initial scope of the management system, refining the scope of the governance system, and producing conclusions for the governance system design. The mapping results show that the three priority domains are APO09 (Managed Service Agreements), BAI10 (Managed Configuration), and DSS01 (Managed Operations). When evaluating the process capability level, these three domains are at level 1, with the target set at level 4. There is a significant gap. Recommendations for improving IT governance operations are provided for each domain, with the priority for improvement on BAI10 to build a solid configuration management foundation, strengthening IT operational processes through DSS01, and improving user satisfaction by focusing on IT services through APO09.

Abstract

As a learning supplement or fulfilment of lifelong learners' needs, the non-formal learning platform, MOOC, is quite attractive to the general public. However, there is a problem that 90% per cent of MOOC students experience dropout. As a result, the name of the organiser is affected so that it decreases its reputation. The method that can be done as risk management is to predict dropout students based on Machine Learning (ML) using a hybrid model built with more than one model so as to improve prediction performance. The first layer with Random Forest (RF) algorithm, and the second layer with Extreme Gradient Boosting (XGBoost) algorithm. The dataset is collected from user activity logs on XuetangX MOOC. The results of testing with K-Fold cross validation and confusion matrix, show that hy model gets an accuracy value of 82.89%, precision 85.03%, recall 93.84%, F1-Score 89.22%, and AUC 81.43%.

Abstract

The role of forests is very important in protecting animal habitats, water sources and oxygen sources for humans. Forest fires often occur in the dry season and are very dangerous if not detected early because they can affect the ecosystem around the forest. One of the protected forests in the Malang area is Raden Soerdjo Forest Park. To protect the Raden Soerdjo Forest Park from fires, temperature and air quality monitoring tools are needed as parameters for the tendency for forest fires to occur in the Raden Soerdjo Forest Park. The system designed uses ESP32 as a system processor and several sensors to support fire detection such as fire sensors, CO2 sensors (MQ 135) and DHT11 to determine the temperature and humidity conditions of the area being monitored. Using Node-RED as an IoT (Internet of Thing) device makes it easier for officers to monitor the temperature and air quality of the monitored area and provide early warning in the form of information via telegram if a fire occurs in the monitored area.

Abstract

PT. XYZ is a producer of margarine and shortening that faces challenges in maintaining the operational reliability of the FLEXIM bag inserter machine. This study aims to address these issues using three methods: Failure Mode and Effects Analysis (FMEA), Reliability Centered Maintenance (RCM), and Logic Tree Analysis (LTA). FMEA is used to identify critical components with the highest risk of failure, RCM to formulate optimal maintenance strategies, and LTA to analyze the cause-effect relationships of component failures within the system. The FMEA results show that the grippers and spoon components have the highest Risk Priority Numbers (RPN), 112 and 120 respectively. The resulting recommendations include increasing inspection frequency, preventive maintenance, and regular component replacement. Implementing these strategies is expected to reduce the risk of failure, improve machine reliability, and minimize operational downtime at PT. XYZ.
