Abstract

The wake effect is an aerodynamic interaction between turbines in a wind farm, where wind flow is blocked by turbines ahead, leading to a total power loss of 10-25%. The wake effect can be controlled by adjusting the yaw-offset angle, pitch angle, tip-speed ratio, or a combination of these strategies. This research aims to compare and determine the most effective control strategy to maximize total wind farm power production. The method involves analyzing and simulating various control strategies to reduce the wake effect. A Gaussian wake-effect model is used to simulate wind flow patterns, turbine interactions, and total wind farm power. Data is generated from simulations under wind speeds of 3 m/s and 10 m/s, and turbine spacing of 7D and 12D. Results show that total wind farm power production increased by 11.41%, 2.21%, 0.00%, and 12.70% for yaw-offset angle, pitch angle, tip-speed ratio, and a combination of the three, respectively. The study identifies the combination of these parameters as the most effective strategy for reducing the wake effect. Proper wake-effect control can significantly boost total wind farm power production, with broader potential applications for commercial wind farms in the future.

Abstract

Coal is one of the energy minerals found in Indonesia with significant potential, particularly in Kalimantan. The objective of this research is to calculate a more accurate estimate of reserves in the study area with a thickness range of 1-1.2 meters. The distribution of the seam generally follows a pattern from Northeast to Southwest with a moderate dip angle of 70-80 degrees. Based on SNI 5015-2011, the geological complexity of the study area falls into the “Complex” category according to SNI 5015-2019 due to the steep inclination of the rock layers. The estimation of coal resources using the Circular Method, aided by software, yielded the following results: measured coal resources of 1,127,778.23 tons, indicated resources of 2,024,364.08 tons, and inferred resources of 2,948,000.06 tons.

Abstract

The research location is in the southern part of Balecatur Village, Kapanewon Gamping. This research aims to determine the quality of groundwater in shallow dug wells located in limestone lithology. The research method used is to use primary data through direct measurement observations in the field and sample testing in the laboratory as well as secondary data to see the quality of ground water in the research area. Based on the results of observations of visual physical descriptions and measurements in the field of color, taste, smell, temperature, pH, TDS at 6 well observation locations, the water generally shows that it is suitable, while based on the analysis of physical and chemical parameters in 2 samples with water quality standards for hygiene purposes and sanitation RI Minister of Health Regulation no. 2 of 2023, samples showed that dug well water had values ​​that exceeded the TDS standard (<300 mg/l) in all observed wells with values ​​between 408 – 601mg/l and color in the Sum-1 well. This TDS value exceeds the quality standard, it is possible for water to be in a well with limestone lithology, because the nature of limestone is easily soluble so that some minerals dissolve in water such as lime (calcium carbonate) and the condition of well water stored in the well for a long time is affected by rock weathering.

Abstract

Regionally, the Semilir Formation is composed of volcanic products. That are dominated by tuff and lapilli, deposited in shallow marine to non-marine environments in the early Miocene to Middle Miocene, the deposition continued until the end of the Miocene. Based on outcrops in the Wukirharjo area, Prambanan, the Semilir Formation, is found to have debris flows and slumps, there is no information about these outcrops regionally, and this is the background to the research. The purpose of the study was to describe the character and facies of the Semilir Formation. The method used was stratigraphic measurement accompanied by paleontological analysis. The results of the study, the Semilir Formation can be divided into 2 facies classes, namely facies F (debris flow) and facies C (turbidity current). The lower facies of the debris flow product is 95 meters thick, composed of dominant lapilli-andesite breccia with a sandstone base mass, with a northwest-southeast paleocurrent direction; facies C is a product of current turbidity in the upper part composed of dominant tuff and sandstone-mudstone repetitions, with a west-east paleocurrent direction. The presence of debris flows and slump as the boundary between the two facies, or the beginning of the deposition of turbidity lithology products at this time.The age of the Semilir Formation in the research area using primary data is N6-N9, with a time gap of N7-N8. The overall age from both primary and secondary data, the Semilir Formation is N4-N16, with a time gap of N7-N8.

Abstract

Tectonic earthquakes often cause hydrogeological responses such as mudflows, but the mechanism by which stress during an earthquake triggers such responses is still unclear. The 2009 Tasikmalaya earthquake (M7.0), for example, triggered a mudflow in Pasirgede Village, Sukahening District, Tasikmalaya Regency, West Java. Another example is the 2016 Pidie Jaya, Aceh earthquake (M 6.5), which also triggered a mudflow in Meunasah Balek Village, Meureudu District, Pidie Jaya Regency, and in Benih Tamiang Village, Rantau District, Aceh Tamiang Regency. In this study, an investigation was conducted on volumetric strain, normal stress, and dynamic stress changes from tectonic earthquakes at the site location experiencing hydrogeological responses. The results show that the hydrogeological response is more caused by dynamic stress changes by seismic waves generated by the tectonic earthquake. This study is useful for understanding the hydrogeological response to stress that occurs during earthquakes, especially in relation to mitigating disaster events..

Abstract

Waste management issues in schools are often overlooked, even though they can negatively impact the environment and health. The Sedekah Sampah program at SD IT Salsabila Baiturrahman aims to address waste problems while providing economic benefits for the school. The methods used include education, actions involving collection, sorting, and selling, and finally, evaluation. The evaluation was conducted by distributing questionnaires to parents and teachers before and after the implementation of the Sedekah Sampah program. The results show a significant increase in the knowledge, attitudes, and behavior of school members regarding waste management, as indicated by the significance value in the statistical test using a paired sample test of 0.000 (less than 0.05). This increase aligns with previous studies emphasizing the importance of education and active participation in waste management. The program also successfully raised funds from waste management, which were used to support school activities. The significance of these results lies in the success of turning waste into a valuable economic resource and raising environmental awareness among students, teachers, and parents.

Abstract

One form of tourism that is becoming increasingly popular in relation to earth sciences is geotourism. Geotourism is a type of sustainable tourism that focuses on the conservation of natural resources. This geoheritage can further develop into a geopark. In addition to exploration, exploitation, and mitigation, earth science also plays a role in revealing geological heritage or earth heritage around us. This research was conducted in Krembangan, an area located in the Panjatan District, Kulon Progo Regency, Special Region of Yogyakarta. This area was chosen due to its rich geological and geomorphological features that are interesting to study. The landscape in Krembangan exhibits a variety of morphological features, including hills, valleys, and rivers. This reflects the processes and events occurring on the earth's surface. The method used in this study is the parameter assessment analysis by Kubalikova (2013), which serves as a modern method for analyzing geotourism potential. The research results indicate that the Krembangan area has geotourism potential in the form of the Goa Kebon waterfall. Based on the feasibility test using qualitative methods, concerning the weight of scientific significance, educational value, economic value, and conservation value, an average total score of 54.5% was obtained, indicating that the Goa Kebon waterfall geotourism can be considered feasible for development as a geotourism site.

Abstract

Used cooking oil, which is often thrown away after use, can have a negative impact on the environment if not managed properly. Through a community service program implemented in Sidomoyo Village, Godean, Sleman, efforts were made to convert used cooking oil into biodiesel as an environmentally friendly alternative fuel for household stoves. This program aims to empower the community by providing knowledge and skills in processing used cooking oil, so that this waste can be reused productively and reduce environmental pollution. The process of converting used cooking oil into biodiesel involves a simple method that can be implemented by village communities at an affordable cost. The use of biodiesel in household stoves is expected to be an alternative energy solution that is economical and environmentally friendly, as well as supporting efforts to reduce domestic waste. The results of this activity show the enthusiasm of the community in adopting this technology, as well as increasing awareness of the importance of managing used cooking oil waste. It is hoped that this program can become a model of curiosity that is implemented in other villages.
