This study aims to analyze the electrical energy consumption of a bench-type drilling machine, RYU RDB 13, by varying machining parameters in the form of spindle speed and feed rate. Electrical energy is a critical aspect of production efficiency in the manufacturing industry, particularly in machining processes that require continuous power consumption throughout the cutting operation. The material used in this study is aluminum 6061, chosen for its lightweight, corrosion resistance, and wide application in the automotive and aerospace industries. The drilling process was carried out using three spindle speed variations: 620 rpm, 920 rpm, and 1280 rpm, along with three feed rate variations: 0.04 mm/rev, 0.08 mm/rev, and 0.1 mm/rev. Current and voltage were measured using a digital wattmeter in real-time, and energy consumption was calculated in wattseconds (Ws) using power calculation formulas. The results indicate that increasing the feed rate and spindle speed leads to higher instantaneous power consumption. However, total energy consumption tends to decrease at higher speed and feed combinations due to shorter machining times. The optimal parameter combination was found at a feed rate of 0.1 mm/rev and a spindle speed of 1280 rpm, which resulted in the lowest energy consumption of 387 Ws and the fastest drilling time. This demonstrates that selecting the right machining parameters not only improves energy efficiency but also maintains or enhances productivity. The observed power consumption pattern typically shows a sharp increase at the beginning of the drilling process, a stable phase during the main cutting stage, and a rapid decrease towards the end of the cut. These findings contribute to a better understanding of the relationship between machining parameters and energy efficiency, serving as a basis for developing sustainable production strategies in the manufacturing sector that prioritize energy savings and cost reduction.

The global demand for energy, particularly fuel oil, continues to increase along with the growth in the number of vehicles and industrial activity. However, limited fossil fuel reserves and the environmental impacts of their use have prompted various studies to find alternative fuels that are more environmentally friendly, efficient, and sustainable. In this context, ethanol and xylene have emerged as two potential fuel additive candidates. Ethanol is known as a biofuel derived from renewable sources and has a high octane rating and oxygen content that can support a more complete combustion process. On the other hand, xylene is an aromatic compound with a high octane rating that can improve combustion stability and reduce the risk of knocking or detonation in engines. This study aims to evaluate the effect of ethanol and xylene additions on the flame characteristics of Pertamax fuel, particularly in terms of flame duration and height. Through a laboratory experimental approach, observations were made on the combustion process of pure Pertamax and several fuel blends with varying ethanol and xylene contents. The results showed that pure Pertamax produced a flame with an average duration of 0.734 seconds and a flame height of 4.5 cm, while one of the best blends, namely the fourth blend containing ethanol and xylene, produced a flame duration of 1.084 seconds and a flame height of 5.7 cm. These findings indicate that the addition of ethanol and xylene can significantly improve combustion performance. These results not only enrich knowledge regarding the combustion characteristics of blended fuels, but also open up opportunities for the development of alternative fuel formulations that are more environmentally friendly, energy efficient, and support reducing dependence on fossil fuels in the future.

This study aims to develop tempeh (Rhizopus oryzae) into tempeh flour to be utilized as the main ingredient in the production of a traditional Indonesian cookie known as kastengel. Tempeh is a rich source of plant-based protein and dietary fiber, yet its application in the processed food industry, particularly in dry baked goods such as cookies, remains underexplored. This innovation is expected to serve as a healthy food alternative while supporting the diversification of local food products. The research employed a Research and Development (R&D) approach, encompassing several key stages: processing tempeh into flour through slicing, drying, grinding, and sieving; formulating kastengel dough using tempeh flour as the base ingredient; and evaluating the final product through both organoleptic (sensory) testing and nutritional analysis. Organoleptic testing involved 10 panelists, including lecturers and students, who assessed the product based on color, taste, aroma, and texture. Nutritional content was analyzed at the Manado Industrial Research and Standardization Agency. The results showed that kastengel made from tempeh flour had a light brown color, a savory-sweet flavor, a distinctive yet pleasant aroma, and a crunchy texture. Laboratory tests revealed the nutritional composition of the product to include 46.12% carbohydrates, 29.82% fat, and 3.92% protein, indicating its potential as a nutritious food option. Most panelists reported a favorable response toward the product. In conclusion, tempeh flour can serve as an effective substitute for wheat flour in the production of kastengel cookies. The final product, branded as “Kastengel Eka,” demonstrates that tempeh-based food innovations can be well-accepted in terms of sensory qualities and possess promising potential as a functional, nutritious, and marketable food product.

Reverse engineering is the process of reproducing or recreating an existing model—whether it is a component, subassembly, or complete product—without relying on the original design documentation or CAD data. One of the key techniques that supports this process is photogrammetry, a method that utilizes a series of photographic images to identify, capture, and reconstruct the geometry of physical objects in three dimensions. Photogrammetry offers advantages such as low cost, portability, and non-contact data acquisition, making it a valuable tool in various engineering and industrial applications. This study aims to analyze the influence of two important factors—namely, the number of photographs taken and the intensity of lighting—on the dimensional accuracy or deviation of 3D models produced through photogrammetry-based reverse engineering. A quantitative experimental approach was used, where both variables were systematically varied to evaluate their effect on model precision. Data analysis was conducted using a Two-Way ANOVA factorial test to determine the statistical significance of each factor and their interaction. The experimental results revealed that using 54 photographs yielded the lowest average dimensional deviation among all tested conditions, although the difference was not statistically significant. Similarly, variations in light intensity showed no statistically significant effect on accuracy, but visually, an illumination level of 200–250 lux tended to provide more consistent and stable model outputs. No significant interaction was found between the two variables, indicating that they operate independently in affecting model accuracy. Overall, the combination of 54 photographs and a light intensity of 250 lux was visually identified as the most effective setup. The findings of this research contribute to the optimization of photogrammetry workflows in reverse engineering, offering practical insights for producing high-quality CAD models for use in design, prototyping, and manufacturing processes.

This study aims to analyze the implementation of the Living Cost Norm in budgeting for foreign official travel costs applied at PT PAL Indonesia. This research uses a qualitative descriptive method that is sourced from primary data obtained through observations, interviews, and review of historical documents on foreign official travel and decrees that are the basis for determining the Living Cost Norm. The results showed that the application of the Living Cost Norm at PT PAL Indonesia had been implemented effectively and was able to provide convenience in the process of preparing the foreign official travel budget. However, it was found that the list of countries in the Living Cost Norm provisions did not cover all destination countries, this situation opened up the possibility of disorientation in the process of budgeting foreign official travel costs whose destination countries were not listed in the Living Cost Norm. It is hoped that this research can provide an in-depth description of the implementation of the policy, as well as solutions and best practices that can be applied by similar industries.

This Community Service (PkM) program aims to provide assistance in financial recording and direct involvement in the production process at the Wisnu Batik SME. The main focus of the activity is to support the sustainability of micro-enterprises based on local culture, particularly through improved management and the preservation of traditional values. The activity was carried out for two months in the form of field work practice (PKL), using participatory observation methods, semi-structured interviews, and direct documentation. One of the main results of the activity was the implementation of a quarterly financial recording system based on SIINAS (National Industrial Information System), which has been proven to improve the accuracy and transparency in the preparation of business reports. Furthermore, the direct involvement of the interns in the traditional batik production process provided important insights into the production stages, the cultural values ​​contained, and the challenges faced in maintaining quality and continuity of production. Analysis of the cost of goods manufactured (COGS) and monthly revenues showed that the Wisnu Batik SME has great potential for sustainable development if managed with a more systematic and professional approach. The synergy between good financial management and production process efficiency is an important foundation in strengthening the competitiveness of SMEs in the midst of market competition.

This study aims to examine the influence of the Gini Ratio, Human Development Index (HDI), and Labor Force Participation Rate (LFPR) on the open unemployment rate in Lampung Province during the 2019–2023 period. The method used in the analysis is a fixed effect model approach with panel data regression, based on secondary data obtained from the Central Statistics Agency (BPS) of Lampung Province. The results of the partial test (t-test) indicate that the three independent variables—the Gini ratio, HDI, and LFPR—do not have a significant effect individually on the open unemployment rate in the region. However, the adjusted coefficient of determination (adjusted R²) value of 88.95% indicates that the model can explain almost all the variation that occurs in the open unemployment rate. This shows that although these variables are statistically insignificant in the model, theoretically they still have an important role in explaining unemployment dynamics in Lampung, along with other factors not yet included in the model. This research provides a strong basis for further analysis in formulating unemployment reduction policies, particularly in regions with economic and social characteristics such as Lampung. Recommendations from this study point to the need for a more comprehensive policy approach that considers other macroeconomic variables such as investment, industrial sector growth, and the quality of education and job training to effectively and sustainably reduce unemployment at the regional level.

This study aims to analyze the influence of capital structure, company size, and liquidity on the financial performance of manufacturing companies in the food and beverage sub-sector listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The food and beverage industry is one of the sectors that has a significant contribution to national economic growth, so understanding the factors that affect its financial performance is crucial. The method used is a quantitative approach with multiple linear regression analysis techniques to test the relationships between variables. The data used comes from the annual financial statements of companies that are included in the sub-sector for the past five years. The results of the study show that partially, the capital structure has a significant influence on the company's financial performance, which is shown by a calculated t-value of 6.414 and a significance value of 0.000 (< 0.05). These findings indicate that the more optimal the capital structure managed by the company, the better its financial performance. On the other hand, company size and liquidity do not show a significant influence on financial performance. The company size has a t-value of -1.493 with a significance of 0.140 (> 0.05), while liquidity has a t-value of 0.765 with a significance of 0.447 (> 0.05). However, simultaneously, these three independent variables together have a significant effect on financial performance, as shown by a calculated F-value of 19,527 and a significance value of 0.000 (< 0.05). The results of this study provide important implications for company management to pay more attention to the management of capital structure, as it is the dominant factor in influencing financial performance. Optimizing capital structure can be used as a strategy to increase the efficiency and competitiveness of the company in the midst of the dynamics of the food and beverage industry.

This study aims to analyze the effects of Carbon Emission Disclosure (CED), liquidity, and leverage on firm value, as well as to examine the role of stock returns as a mediating variable. A quantitative research method was employed, utilizing multiple regression and path analysis on data from companies listed on the Indonesia Stock Exchange, particularly within sectors related to environmental issues. The findings indicate that CED significantly affects firm value both directly and indirectly through stock returns. Stock returns also demonstrate a significant positive effect on firm value. In contrast, liquidity and leverage do not exhibit significant effects, either directly or when mediated by stock returns. These results suggest that investors respond more to non-financial information, especially sustainability disclosures, than to traditional financial indicators. This study implies that companies should enhance the quality of their CED reporting as a strategy to build investor trust and sustain long-term firm value. This study is limited to companies listed on the Indonesia Stock Exchange, focusing mainly on environmentally related sectors, which may limit the generalizability of the results to other industries or geographical contexts. Moreover, reliance on quantitative methods and secondary data may overlook qualitative perceptions of stakeholders. Future research is recommended to expand sampling across diverse industries and regions to validate these findings further. Incorporating qualitative approaches could provide deeper insights into investor reactions to carbon emission disclosures. Companies are encouraged to adopt more transparent and standardized carbon emission disclosure practices and integrate sustainability into their broader strategic management to effectively enhance firm value.
