Abstract

This research aims to monitor the performance of a 2x100Wp Solar Power Plant (PLTS) using the parameters of current, power, and solar intensity. The monitoring system is designed to record and analyze the electrical output of the solar panel in real-time. The experimental method is used by collecting data directly through current and voltage sensors, as well as light sensors connected to a microcontroller. Data was collected to see the relationship between solar intensity and electrical power generated. The test results show that the intensity of the sun greatly affects the amount of current and power generated by the solar panel. This monitoring system can be a tool for learning and analyzing the performance of small-scale solar power systems in a laboratory environment.

Abstract

Agricultural waste such as pineapple crown leaves (Ananas comosus) has not been optimally utilized, despite its high cellulose fiber content, making it a potential alternative raw material for paper production. One of the main challenges in this process is controlling the paper's moisture content, as excessive water content can reduce product quality. This study aims to investigate the effect of sodium hydroxide (NaOH) concentration on the moisture content of paper made from pineapple crown leaf fibers. Three NaOH concentrations (2%, 8%, and 14%) were applied during the pulping process to remove lignin and hemicellulose, followed by gravimetric analysis of the resulting paper’s moisture content. The results showed that the 8% NaOH treatment produced the lowest moisture content of 8.35%, while the 2% NaOH treatment resulted in the highest moisture content of 10.34%. One-way ANOVA indicated that variations in NaOH concentration had a statistically significant effect on moisture content (p < 0.001). The findings revealed a non-linear relationship between NaOH concentration and moisture content, with 8% being the optimal point. A lower concentration resulted in dense fiber structures that retained water, while a higher concentration led to the formation of cellulose II, which is more hygroscopic. This study highlights the importance of optimizing NaOH concentration in paper production from agricultural waste to achieve the best quality.

Abstract

Operational efficiency and product quality are crucial for enhancing the competitiveness of MSMEs in the era of globalization and digital transformation. This study explores the application of Six Sigma to reduce product defects at MSME X, a footwear manufacturer in Bandung. Using a quantitative approach with interviews, documentation, and observation, the research applied the DMAIC (Define, Measure, Analyze, Improve, Control) framework to identify and address quality issues. Key defects included joint cracks, under-fill, and press marks. Analysis using Pareto charts and cause-and-effect diagrams revealed root causes such as inadequate operator training, inconsistent raw materials, and irregular machine maintenance. To address these, the company implemented retraining programs, improved standard operating procedures, and adopted digital monitoring systems. As a result, the defect rate was reduced by 40%, and the sigma level improved from 3.9 to 4.45. The study confirms that Six Sigma can significantly enhance both product quality and operational performance. These findings offer valuable insights for other MSMEs aiming to adopt structured quality improvement methods to remain competitive in the global market.

Abstract

This study aims to develop and modify learning media in the form of a motorcycle headlight electrical trainer to improve the effectiveness of learning for students at State Vocational High School (SMK) 4 Lhokseumawe. Conventional learning media are often less able to provide a real picture of the electrical system of motor vehicles, so it is necessary to develop more representative and interactive aids. The method used in this study is the research and development (R&D) method with the Borg and Gall model. The results of the modification include the addition of visual indicators (LED lights), more systematic wiring, and an electric current disturbance simulation panel. The feasibility test was carried out by media experts, material experts, and limited field trials on vocational high school students. The evaluation results showed that the modified trainer was very suitable for use as a learning medium, in terms of clarity of function, ease of use, and visual appeal. The use of this trainer was able to significantly improve students' understanding of the motorcycle headlight electrical system. .

Abstract

Changes in land surface temperature are one of the important indicators in monitoring global environmental change. In the last decade, increasing surface temperatures have become a global concern, as they have the potential to affect ecosystems, air quality, water availability and human health. In addition, increasing land surface temperature also has a direct impact on the urban heat island phenomenon, which can worsen environmental conditions in urban areas. In this context, analyzing periodic changes in land surface temperature is important to understand the patterns and factors that influence these changes. The objectives in conducting this research, namely: Analyzing the land surface temperature, Creating a regional land surface temperature map and Analyzing changes in land surface temperature from the land surface temperature map of Pariaman City in 2015, 2019, and 2023. Based on the results of the analysis of changes in land surface temperature using Landsat 8 OLI/TIRS images in 2015, 2019, and 2023, it was found that there were significant variations in temperature changes in several areas. Landsat 8 image data is processed through several stages, starting from converting Digital Number (DN) values to spectral radians, brightness temperature, to estimating Land Surface Temperature (LST) in Celsius units. The analysis shows that there was a significant increase in land surface temperature during the period, especially in urban and coastal areas. In 2015, the majority of areas had temperatures of 20°C-24°C, while in 2019 it shifted to 24°C-28°C, and in 2023 it was dominated by temperatures of 28°C-32°C and above 32°C. These changes reflect a significant local warming trend, influenced by human activities and land use change. This research is expected to contribute to the understanding of environmental dynamics and support spatial planning that is more adaptive to climate change.

Abstract

Empty oil palm bunches processed by palm oil mills in Indonesia are still abundant, reaching 56.35 million tons per year. Empty oil palm bunches contain around 40% cellulose, so they can still be used for various derivative products, one of which is composite products. The use of empty oil palm bunches as raw materials for Bioplastic production is a series of ongoing research, one of which is starch-cellulose blend, but until now it has not been successfully commercialized. The design of the starch cellulose blend bioplastic industry using palm oil as raw material produces two factories, namely a cellulose factory and a composite bioplastic factory. Both factories are designed in separate buildings. The separation of cellulose from TKKS uses a chemical method with soda, after mechanical treatment of size reduction. The industry is designed in 3 scales of production capacity, namely a large scale of 190,000 tons / year, medium 115.00 tons / year, and small 40,000 tons.year. The financial analysis of the three scales of production capacity as a whole is declared feasible. Profit margin is calculated at a minimum of 17.6%. The average payback period is between 3-5 years with an IRR of 24-49%. Analysis of the economic value produces an EScale index of 0.64 which indicates that the economic scale has been achieved. The economic scale of the starch cellulose blend bioplastic industry from TKKS is at a production capacity of 40,000 tons per year with a minimum supply of TKKS raw materials of 20,203 tons/year. At the smallest economic scale, the BEP is actually only 6627.4 tons/year, where this condition can be achieved because the industry has relatively small fixed costs.

Abstract

The increasing demand for sustainable agricultural practices has led to the adoption of hydroponics, a method of growing plants in nutrient-rich solutions without soil. This method is particularly effective in controlled environments where resource efficiency is paramount. However, the success of hydroponic systems depends heavily on precise nutrient management, especially for micro-nutrients, which are crucial for plant health and productivity. Traditional methods of nutrient monitoring are often labor-intensive and lack the real-time responsiveness needed for optimal nutrient control. This study addresses the challenge of real-time nutrient management in hydroponic systems by developing a miniature sensor system integrated with Internet of Things (IoT) technology. The proposed system is designed to detect micro-nutrient concentrations accurately and transmit data in real-time to a cloud platform for continuous monitoring and automated control. Advanced algorithms are employed for data processing and calibration, ensuring high accuracy in detecting micro-nutrient levels. The system was tested in a controlled hydroponic environment, where it demonstrated high accuracy with minimal error margins, validated by a consistently low Mean Absolute Error (MAE). The integration of IoT allowed for seamless data transmission and real-time analysis, enabling immediate adjustments to nutrient levels as needed. This research contributes to the advancement of precision agriculture by providing an effective solution for real-time nutrient management in hydroponic systems, potentially improving crop yields and resource efficiency.

Abstract

Waste management problems in Kudus City show high complexity, marked by an increase in the volume of daily waste generation that is not balanced by an adequate handling system. This study aims to optimize the waste management system in an integrated manner with an industrial engineering approach, especially through the application of the Lean Waste Management concept, redesigning facilities and logistics, and strengthening community participation based on Human-Centered Design (HCD). A qualitative method with a case study approach was used, with data triangulation techniques in the form of in-depth interviews, direct observation, and document analysis. The results of the study showed that 75% of households did not sort their waste, only 2 out of 6 TPSTs were active, and the TPA capacity had exceeded its limit since 2022. The efficiency of the transportation system is also low due to suboptimal routes and frequencies. This study offers solutions based on technology integration, facility redesign, logistics optimization, and community empowerment. With a systemic approach based on industrial engineering, an efficient and sustainable waste management model can be applied, not only in Kudus, but also in other areas with similar challenges.

Abstract

Students' understanding of the concept of motion of objects on inclined planes still shows obstacles, especially when applied in real practice. This study aims to see the extent to which students understand the concept through simple experiments and questionnaires. The main focus of the study was on the results of the practicum, where the block slid faster on a smooth plane (an average of 1.25 seconds) than on a rough plane (an average of 1.61 seconds). This time difference reflects the effect of friction on the motion of objects, but some students were unable to explain the difference correctly. This indicates that there are still misconceptions in understanding the concepts of force and motion. Meanwhile, the results of the questionnaire only reinforced that most students felt the need for direct practice to understand this material. Thus, a practice-based learning approach is very important to strengthen students' conceptual understanding in Basic Physics courses.
