Abstract

This study is an experimental research that investigates the effect of varying solar panel tilt angles (180°, 15°, 30°) and adding an 80% darkness level glass film layer on power and efficiency. The study compares the results with and without the glass film for each tilt angle. The research methodology employed includes literature review and experimental development. The literature review provides a foundation for understanding the fundamental theories of solar panels, their working principles, and the impact of tilt angle on power and electrical efficiency. The results indicate that the tilt angle of solar panels significantly affects power and efficiency. The solar radiation received per unit area for each tilt angle (180°, 30°, 15°) is 920.3 W/m², 1002 W/m², and 1092.5 W/m² at 10:00 WIB, respectively, with the highest radiation observed at a 15° tilt angle. The power input to the solar panel without glass film for each tilt angle (180°, 30°, 15°) is 635 watts, 691.38 watts, and 753.82 watts at 10:00 WIB, respectively, with the highest power recorded at a 15° tilt angle. The efficiency of the solar panel without glass film for each tilt angle (180°, 30°, 15°) is 50.29%, 46.96%, and 53.46% at 14:00 WIB, respectively, with the highest efficiency achieved at a 15° tilt angle

Abstract

The primary aim of this paper is to offer key insights into solar energy and waste heat adsorption cooling systems, as well as to present a helpful approach concerning the design aspects of the adsorbent bed utilized in adsorption cooling. In recent decades, solar-powered water purifiers have primarily been utilized for heating water in residential settings. In contrast, solar cooling systems have mainly been designed for demonstration purposes. It indicates that absorption cooling systems are better suited for large buildings, while adsorption cooling systems show greater promise for smaller air conditioning units. It is advised to plan solar-powered systems in public facilities. Highly efficient heat pumps are regarded as the best supplementary heat providers since they can operate independently of weather conditions.

Abstract

The development of quality road infrastructure is a key factor in supporting economic growth and inter-regional connectivity. This study aims to analyze the basic characteristics of aggregates and the effect of variations in size and distribution of aggregates on the performance of hot asphalt mixes. Fine and coarse aggregate samples were obtained from two quarry locations, namely Batang Atokan (Pasaman) and Gunung Nago (Padang), by testing using the Marshall method. The results showed that the aggregate from Sungai Atokan Quarry had the highest maximum stability of 1440.99 kg at 5% asphalt content, and showed the highest Marshall Quotient (MQ) value of 371.66 kg/mm. In contrast, Gunung Nago Quarry achieved the highest stability of 1211.93 kg at 7% asphalt content, but experienced a decrease in the VIM value below the specification limit at high asphalt content, indicating a risk of bleeding. The optimum asphalt content value for each quarry was 6.5% for Sungai Atokan and 6.0% for Gunung Nago. Comparative analysis shows that the mixture from the Atokan River Quarry is stiffer, more resistant to deformation, and suitable for heavy traffic, while the mixture from Mount Nago is more plastic and sensitive to excess asphalt content. The results of this study are expected to serve as a technical reference in aggregate selection and hot asphalt mix planning to improve road pavement quality in West Sumatra.

Abstract

The use of drones as a weather monitoring system has seen significant progress, particularly in reaching difficult-to-access areas and collecting real-time atmospheric data. This study aims to analyze the effect of variations in drone altitude and flight speed on the accuracy of weather parameter measurements, such as temperature and wind speed, using an anemometer sensor. The experiment was conducted in an area located approximately 1,800 meters above sea level, by flying a quadcopter drone at altitudes of 50 m, 100 m, and 150 m above ground level. The results show that variations in flight speed affect the stability of wind measurements, while temperature shows high stability at various altitudes. This study confirms the potential of using UAVs to support direct weather observation systems as part of efficient disaster mitigation.

Abstract

The increasing demand for electrical energy in Indonesia encourages the availability of a reliable, efficient and stable power distribution system, especially in maintaining voltage quality during the transmission to distribution process. One of the main challenges in the distribution system is the occurrence of voltage drops which if not controlled can reduce energy efficiency and damage electrical equipment. In overcoming these problems, this research applies the Artificial Neural Network (ANN) method based on the backpropagation algorithm as an alternative approach in analyzing and predicting voltage drops in power distribution networks. Simulations were conducted using MATLAB R2024b software with input variables in the form of voltage, power factor, conductor length and diameter, cable type resistance, reactance, and load current. Meanwhile, the output variable analyzed is voltage drop. The simulation results show that the ANN model has a high predictive ability indicated by the Mean Square Error (MSE) value of 0.012743, Root Mean Square Error (RMSE) of 0.11289, Mean Absolute Error (MAE) of 0.033586, and Mean Absolute Percentage Error (MAPE) of 6.4292 %. This low error value indicates that the ANN is able to recognize complex patterns between input variables and provide adaptive responses to various variations in distribution system conditions so that the application of ANN using the backpropagation algorithm proves effective and efficient as a tool in supporting the technical decision-making process.

Abstract

Centrifugal pumps are essential components in refinery processing systems, including those at PT Kilang Pertamina Internasional RU II Dumai. One of the pumps in operation, the overhung type 212–P17, has experienced a jammed condition affecting its performance. This study aims to analyze the potential failure modes of the pump components using the Failure Mode and Effect Analysis (FMEA) method and to determine corrective action priorities based on the Risk Priority Number (RPN). The analysis focused on four key factors: material integrity, shaft alignment, lubrication condition, and clearance. The results indicate that shaft misalignment had the highest RPN of 324, followed by lubrication failure with an RPN of 160. These findings suggest that corrective measures should prioritize shaft realignment and lubrication management. The FMEA approach has proven effective in identifying critical components and structuring a preventive maintenance strategy to enhance the operational reliability of the pump system.

Abstract

Gas lock is defined as a fluid flow problem where the flow is blocked by a gas phase, inhibiting the production flow rate. This occurs due to the release of free gas in oil with a high gas-oil ratio (GOR). This condition arises when the pump intake pressure (PIP) or fluid over pump (FOP) is lower than the bubble point pressure (Pb) of the oil. Initial indications of free gas formation can be observed from erratic amp-chart readings, high annulus pressure, and the pump operating below its efficiency. To address gas lock issues in ESP pumps, additional equipment such as a gas separator can be installed below the surface, and PIP should be maintained above the Pb. The installation of a gas separator in the pump helps reduce the entry of free gas into the pump, while free gas is discharged into the annulus casing. In this thesis, the researcher uses a case study on a producing well with high GOR values of 100 mscf/day, a design rate of 850 BFPD, and a pump intake pressure (PIP) higher than the well's bubble point pressure (Pb) at 150 psi. Based on data processing using Prosper V11 software, the ESP pump in well Y was replaced from a REDA DN1300 to a REDA DN1100, resulting in a gas separator sensitivity value of 89%. The best pump efficiency achieved was 62%, and the optimal production rate obtained was 1330 RB/day.

Abstract

A vortex turbine is a turbine that operates by utilizing a vortex flow as a drive for turbine blades which then the turbine shaft is connected to a generator to convert shaft mechanical energy into the form of electrical energy. In this study a test will be carried out on a vortex turbine with a head of 1 m, a flow rate of 0.12 m3/s. In the testing process, 3 types of blades will be used, namely straight blades, curved blades and finned curved blades. After testing, it can be concluded that the highest power is found in the curved blade of 959.08 Watt and then the finned curved blade is 714.38 Watt, while the lowest power is found in the straight blade type of 582.48 Watt. The resulting rotation can be seen in the graph below. The highest rotation is found in the finned curved blade of 540.00 rpm and the next is the curved blade of 517.67 rpm, while the lowest rotation is found in the straight blade type of 510.67 rpm. For the efficiency of each metal blade, it can be seen that curved blades are still the highest followed by curved blades with finned blades, the lowest being straight blades with salty blade efficiencies of 98%, 73% and 59%
