Abstract

The construction industry in Indonesia is growing rapidly, playing a crucial role in the country's economic, political, and social development. However, alongside this rapid growth, issues such as project delays are inevitable. The construction project of the Indonesian Maritime Polytechnic, for instance, has experienced significant delays, which can lead to increased costs, waste of human resources, and disputes among the involved parties. Understanding the primary causes of these delays is essential for developing effective strategies to avoid future delays. This analysis uses both qualitative and quantitative methods to identify the root causes of delays. Data was collected through surveys of respondents involved in the project, including project managers, field staff, and consultants. The analyzed causes of delays include insufficient funding, increases in raw material costs, additional costs, contract document errors, poor communication, and slow decision-making. To minimize delays and their impacts, several recommendations can be made: effective strategic planning, improved communication, increased staff, accurate initial cost estimates, and good management. By implementing these recommendations, the Indonesian Maritime Polytechnic construction project can be completed more effectively and efficiently, and future delays can be avoided.

Abstract

Wind Turbine Blades are one of the renewable energy sources that are the main solution to reduce excessive use of conventional fuels. Wind Turbine Blades absorb kinetic energy into mechanical energy which is then converted into electrical energy by the generator. This study uses the National Advisory Committee for Aeronautics (NACA) 1.2 horizontal axis wind turbine blade design with a taper type (having a wide base and a small tip). The initial wind turbine blade data was obtained rotating at a wind speed of 3.5 m/s with a voltage of 5.1 Volts. This blade design was carried out using maximum wind speed data of 9.5 m/s and minimum wind speed data of 3.6 m/s, then current and voltage data were obtained. The results of this study confirm that the design of this wind turbine blade affects the efficiency of converting wind energy into electricity. This taper type wind turbine blade is designed to produce optimal performance in a certain wind speed range.

Abstract

This research aims to design an Aircraft Jacking control system for the Boeing 737-800 to automatically balance the aircraft's inclination using an MPU6050 sensor and servo actuators. The system can detect pitch and roll angles with an accuracy of ±0.5° and an average response time of 150 ms. Based on tests using five datasets, the balancing time ranges from 400 to 600 ms, depending on the initial imbalance. In Dataset 5, with a pitch of 3.5° and a roll of -2.3°, the system required 600 ms to achieve balance, demonstrating its ability to handle critical conditions. The servo actuators successfully adjusted the jacking height within a range of 2 cm with a precision of ±0.02 cm, while the OLED-based monitoring system allowed operators to observe the inclination angles in real-time. Furthermore, ESP-NOW-based communication achieved a data transmission success rate of 98%, supporting efficient centralized control. This research demonstrates the system's effectiveness in balancing the aircraft quickly and accurately, providing a foundation for further development under extreme conditions and energy efficiency improvements.

Abstract

The rapid advancement of technology has led to an increasing demand for electrical energy. One of the efforts to meet this demand is the development of micro-capacity power generation systems utilizing heat energy. Heat energy can be harnessed using thermoelectric elements. This study aims to design and develop a portable power generation system that utilizes solar heat as an energy source. The prototype uses six TEC 1-12706 thermoelectric modules to generate electricity designed specifically to recharge devices such as phones, power banks, and flashlights. Solar heat is concentrated on the thermoelectric modules using Fresnel lenses, while heatsinks are employed for cooling. The thermoelectric modules are connected in series to produce sufficient voltage, which is then boosted by a boost converter. The generated electrical energy is stored in a battery to ensure voltage stability despite temperature fluctuations. This device can also operate at night due to the energy stored in the battery. Test results show that the average output voltage without load ranges from 9.49V to 9.56V, with an average temperature of 45.2°C at the thermoelectric modules. In load tests, the device successfully charged a Pixel 5 phone (5000 mAh battery) from 4% to 70% in 95 minutes. These results demonstrate the potential of this system as a reliable and environmentally friendly portable energy solution.

Abstract

The largest source of energy currently utilized is still predominantly from fossils. Fossil energy sources are non-renewable so over time they will run out. So it is necessary to utilize renewable energy sources. One renewable energy source that is environmentally friendly and easy to obtain is wind energy. Wind is a collection of air that is experiencing movement due to a difference in pressure on the earth's surface. Wind will move from areas of high pressure to areas of lower pressure. Experimental research on wind energy is a useful energy that can be put to good use. Wind energy is a form of energy that comes from utilizing air flow in the atmosphere to produce mechanical or electrical energy. The main technology used to utilize wind energy is a wind turbine, which converts wind kinetic energy into electrical energy through a generator. Which of course also requires sufficient wind speed so that the wind turbine can rotate and produce mechanical movement in the form of rotational torque which can then be converted into electrical energy. Wind energy has great potential as a clean, sustainable and environmentally friendly resource, as it does not produce greenhouse gas emissions or hazardous waste during its operation. However, wind energy development faces challenges such as fluctuations in wind speed, large land requirements, visual impacts, and potential disruption to local ecosystems. With technological innovation and careful planning, wind energy can be a significant solution to meet global energy needs in a sustainable manner.

Abstract

Abstract. From the perspective of Micro, Small, and Medium Enterprises (MSMEs), fluctuations in raw material prices are highly concerning as they can significantly impact business stability. While MSMEs may tolerate price fluctuations to some extent, from an industrial engineering perspective, such a passive approach contradicts the principles of continuous improvement. This study seeks to predict the price of large red chili peppers using five regression models implemented through Orange Data Mining: Linear Regression, Support Vector Machine, Decision Tree, k-Nearest Neighbors (kNN), and Gradient Boosting. Due to the limited availability of daily data, particularly within a daily timeframe, the study utilized weekly data spanning three years. The results of the Test and Score evaluation shows Gradient Boosting as the best-performing model, achieving a Mean Absolute Percentage Error (MAPE) of 0.7%. However, the MAPE for predictions in January 2025 increased to 15.8%. This error is expected to decrease as more weekly data becomes available to mitigate the inaccuracies inherent in this model. Keywords: prediction, red chilli, regression, supervised learning , orange data mining. Abstrak.

Abstract

Indonesia's dependence on oil and gas imports has become a significant challenge to the country's economic stability, with impacts on the trade deficit, global energy price fluctuations, and fiscal dependence. This study aims to evaluate the economic impact of efforts to reduce Indonesia's dependence on oil and gas imports, focusing on the implications for economic growth, trade balance, and national energy security. The methods used include secondary data analysis, macroeconomic modeling, and simulation of the impact of energy policies such as increasing domestic oil and gas production, energy diversification, and renewable energy development. The results show that reducing dependence on oil and gas imports has the potential to reduce pressure on the trade balance and foreign exchange reserves, and improve long-term energy security. However, the transition to domestic energy security requires large investments in the renewable energy sector, supporting infrastructure, and policies that support energy efficiency. This study suggests the need for an integrated policy strategy between the government, private sector, and society to achieve the goal of reducing oil and gas dependence and improving Indonesia's economic competitiveness.

Abstract

The problem of household waste, which accounts for 50-70% of the total waste in Indonesia, mainly in the form of organic waste such as food and vegetable scraps, is a major challenge in environmental management. Composting is an effective method of managing organic waste by turning it into compost. However, organic waste management in Indonesia is still minimally practiced because it is considered to have no economic value. A 50 kg capacity composter machine equipped with a vertical mixer and using an electric motor can increase composting efficiency. This study aims to analyze the feasibility of composter machines and to analyze the effect of speed and mixing time on composter machines on the homogeneity of organic waste. The research method used is quantitative experimental with factorial experimental design (DOE) to analyze the effect of speed and stirring time on the composter machine on the homogeneity of organic waste. The stirring speed variations tested were 30, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the single mixer composter machine proved to be feasible and reliable in producing homogeneous organic waste, with a high process capability value of 5.86. The use of mixing speed from 30 RPM to 60 RPM and mixing time from 20 minutes to 40 minutes significantly increased the homogeneity of organic waste, with the highest value of 97.54% at 60 RPM speed for 40 minutes.
