Abstract

The company converted rubber plantations into palm oil plantations to enhance operational efficiency. Palm oil is considered more profitable as its maintenance is simpler, production costs are lower, and harvesting can be done year-round without being affected by the seasons, unlike rubber, whose production decreases significantly during the rainy season. This is expected to increase the company's overall productivity and profitability. This research aims to determine the productivity of palm oil and the soil nutrients in the rubber-converted land at Kebun Tamora, PT. Perkebunan Nusantara V, Kampar Regency, Riau. The research was conducted from September 1 to November 1, 2023, using a quantitative and qualitative descriptive analysis method, utilizing secondary data. The results indicate that plantation productivity varies but has shown continuous increases year after year. For example, for the 2014 planting year, production increased from 16.150 tons/ha in 2018 to 33.127 tons/ha in 2022, while for the 2015 planting year, productivity reached 31.867 tons/ha in 2022.

Abstract

The tool design stage uses the help of the AutoCAD application. The next stage is the manufacture of used oil-fueled stoves. Followed by testing the used oil-fueled stove. Based on the results of the two stoves that have been tested above, it is concluded that the time to boil 5 liters of water in a used oil-fired stove is 2 minutes faster than a gas stove, this can be proven in the results, namely the time to boil water in a used oil-fired stove is 7 minutes, while the time it takes to boil water in a gas stove is 9 minutes. The stove that is produced is able to be an alternative when the price of fuel in the form of gas soars so that it can be a solution for cooking with fuel at an affordable price. Researchers need to pay more attention to the selection of stove wall coating materials so as not to conduct excessive heat.

Abstract

Three-dimensional printing (3D printing) technology has developed rapidly and offers innovative solutions in the manufacturing industry, especially for replacing damaged machine components. This research aims to analyze the perception and effectiveness of this technology as an alternative through empirical data from 300 respondents. The test results show that perceptions of 3D printing's ability to replace traditional components, the quality of the print results, and environmental benefits are significantly influenced by the respondent's level of experience (p-value < 0.05). However, aspects of cost efficiency and ease of application of technology show uniformity of perception across all groups of respondents, indicating the potential for broad application of technology. The normality and ANOVA tests performed confirmed the validity of the data, supporting the use of parametric statistical analysis. These findings underscore the ability of 3D printing to reduce costs and production time, while highlighting key challenges related to material strength and initial investment. This research recommends the development of materials, hardware, and ongoing education to increase the acceptance and effectiveness of the application of this technology in the manufacturing industry.

Abstract

In an increasingly competitive industrial era, reducing waste and increasing operational efficiency has become a primary focus for many organizations. The 5S method, namely Seiri (Sort), Seiton (Arrange), Seiso (Clean), Seiketsu (Standardization), and Shitsuke (Discipline), which originated in Japan and was introduced into the Toyota production system in the 1950s, offers a systematic approach to creating an orderly and clean work environment. This research aims to explore the implementation of 5S at PT XY, with a focus on its impact on operational efficiency and reducing waste in the cement production process. The methodology used in this research includes literature studies and case studies, where data is collected through interviews, direct observation and documentation analysis. The research results show that implementing 5S can increase productivity, create a more organized work environment, and increase employee satisfaction. However, there are several challenges in implementation, especially in the aspects of standardization and discipline among employees. This research also identified problems faced in the project warehouse, such as a lack of personnel, insufficient area, and misunderstandings in shipping goods. Recommendations for improvement include employee training, establishing more comprehensive procedures, and grouping items by type to increase efficiency. Thus, it is hoped that the application of the 5S method at PT XY can create a better work culture and support the sustainability of operational efficiency practices in the future. These findings provide valuable insights for other industries looking to implement 5S to improve their performance and competitiveness.

Abstract

As a transportation infrastructure, roads are essentially an important element in realizing economic growth and achieving healthy and dynamic social stability. Therefore, the performance of road sections needs to be considered. Road section performance can be defined as the extent to which the road is able to carry out its function. A survey conducted on 4 different days showed the performance of road sections during peak hours with a traffic volume (V) in the direction of Bangkinang-Payakumbuh of 905 vehicles/hour and in the direction of Payakumbuh-Bangkinang of 840 vehicles/hour, so that the total traffic volume on the Pasar Kuok road section is 1683 vehicles/hour. The total traffic flow (Q) on the Pasar Kuok road section is 1589.9 smp/hour. The capacity (C) on the Pasar Kuok road section is 2523.53 smp/hour. The degree of saturation (DS) of the Pasar Kuok road section is 0.61 while the V/C ratio on the Pasar Kuok road section is 0.64. That the class of side obstacles on the Pasar Kuok road section is very high (VH). It is concluded that the Sumbar - Riau road section, precisely at the Kuok market, experiences a very high saturation point on market days, namely Tuesday due to the activities of the Kuok traditional market. Because of the many vehicles parked on the shoulder of the road, street vendors (PKL) on the roadside and many people passing by on the road.

Abstract

Bangkinang, the capital of Kampar District with an area of 177.2 km² and a population of 39,793, experiences a tropical climate that contributes to elevated surface temperatures. Increasing population, vehicle emissions, and industrial activities intensify urban heat, while limited vegetation density exacerbates the Urban Heat Island (UHI) effect. This study analyzes surface temperatures in 2021, 2022, and 2023 using Landsat 7 ETM+ and Landsat 8 OLI/TIRS data. Land Surface Temperature (LST) was calculated using the Single Channel Algorithm (SCA) method, resulting in average temperatures of 27.755°C (2021), 26.644°C (2022), and 27.130°C (2023). The Pearson correlation between LST and field temperature from BPS produced an Rxy value of 0.226, indicating a weak correlation. The UHI threshold analysis shows that the area affected by UHI decreased consistently from 2021 to 2023.

Abstract

Efficient facility layout plays a critical role in improving operational performance, learning effectiveness, and occupational comfort in vocational education workshops. This study examines the redesign of a motorcycle engineering and business workshop at a public vocational high school in Indonesia using the Systematic Layout Planning (SLP) method. The existing layout exhibited inefficient material flow, excessive travel distances, and poor spatial organization, leading to fatigue among students and reduced instructional productivity. A qualitative descriptive case-study approach was employed, supported by direct observation, process mapping, and activity relationship analysis. The SLP procedure was applied through the development of Operation Process Charts, Activity Relationship Charts (ARC), Activity Relationship Diagrams (ARD), and block layout alternatives. The proposed layout demonstrates a substantial reduction in inter-facility travel distance and improved logical sequencing of learning activities. The findings confirm that SLP is an effective and adaptable approach for optimizing educational workshop layouts, contributing to improved operational efficiency and a safer, more conducive learning environment.
