Consistent and efficient concrete quality in each implementation is one of the main factors in the success of construction projects. Concrete as a structural material requires strict quality control in order to meet the technical standards that have been set. One way to improve the quality of concrete is to add certain additives to the job mix formula (JMF). This research is focused on the application of SG type additives known as chemical-based additives to improve the properties of fresh concrete and hard concrete. SG additives have an important function in increasing workability, speeding up or slowing down the binding time as needed, maintaining quality stability, and strengthening concrete finishes. In this study, a comparison was made between a concrete mixture with SG additives and a concrete mixture without additives. The tests included slump parameters, initial binding time, and compressive strength at 7 and 28 days of age. The test results showed a significant difference, especially in the improvement of the consistency and compressive strength of concrete with the use of additives. The results of the discussion showed a comparison of Trial Mix 1 and Trial Mix 2 that are different in terms of material composition, cost efficiency, and compressive strength of concrete. Trial Mix 2 with the composition of cement, admixture, water, and aggregate (sand and split) showed more optimal results. The compressive strength achieved was 821,396.00 kg/cm² at the age of 28 days. In terms of cost, Trial Mix 2 requires Rp. 351,582.00 per m³, with an efficiency difference of around Rp. 32,953.00 per m³ compared to the previous mix

Iron deficiency anemia is a significant public health problem in pregnant women, because it can cause maternal and fetal complications. Compliance with iron tablet consumption is often low due to limited knowledge, side effects, and cultural misconceptions. Leaflet-based education is a low-cost intervention that has the potential to improve understanding and compliance. This study aims to analyze the effect of leaflet education on the adherence of iron tablet consumption in pregnant women at the Pujon Health Center, Batu. The research design used a quasi-experiment with a pretest-posttest control group design. A total of 40 pregnant women were divided into an intervention group (n = 20) that received leaflet education and a control group (n = 20) that received standard counseling. Compliance was measured over four weeks through self-consumption records and tablet count calculations, while knowledge was assessed with a structured questionnaire. Data analysis used the Chi-square test with a significance level of p < 0.05. Results showed a significant improvement in adherence in the intervention group, with 70% of pregnant women complying compared to 15% in the control group (p = 0.001). Leaflet education also increased knowledge scores and consistency of iron tablet consumption. The conclusion of this study confirms that leaflet education is effective in increasing iron supplementation adherence, so it is recommended to be integrated into routine antenatal services to prevent anemia and support maternal and fetal health.

Urinary incontinence is a common medical condition among older women, characterized by the involuntary leakage of urine due to impaired bladder control. This condition not only affects physical health but also has significant psychosocial impacts, including reduced self-confidence and quality of life. Non-pharmacological interventions, particularly pelvic floor muscle exercises, have been recognized as effective strategies to strengthen the bladder sphincter and pelvic floor muscles, thereby enhancing urinary retention. The present study aimed to evaluate the effectiveness of pelvic floor muscle exercises in reducing the frequency of urinary incontinence among elderly women. An experimental design with a one-group pretest–posttest approach was employed. The study population consisted of 64 elderly women receiving care at the Gunung Pati Public Health Center in Semarang, from which 45 participants were selected through purposive sampling based on inclusion criteria. Data were collected using structured questionnaires and clinical observation to assess the frequency of urinary incontinence episodes before and after the intervention. Statistical analysis was performed using the Wilcoxon signed-rank test, and the results indicated a significant reduction in urinary incontinence episodes following the exercise program, with a p-value of <0.001. These findings suggest that pelvic floor muscle exercises are a simple, cost-effective, and non-invasive intervention to manage urinary incontinence in elderly women. Implementing such exercises in community health programs can play a vital role in promoting the well-being and independence of older women. The study recommends incorporating pelvic floor muscle training into routine elderly care services and encourages further research with larger samples and longer follow-up periods to confirm the long-term benefits.

This research develops an automated temperature control system for water heaters, that is both efficient and stable, driven by the need for energy-saving heating solutions, particularly for marine applications. The main objective was to create an automatic system capable of maintaining water temperature within an optimal range while maximizing energy efficiency through the use of thermal storage materials. The methodology involved an on-off control system based on a microcontroller as the main controller, capable of processing temperature sensor data in real time. This system intelligently activates and deactivates the heater to keep the water temperature stable. Paraffin wax was used as a latent heat storage medium, playing a crucial role in gradually storing and releasing thermal energy to support temperature stability. An automatic water heater system based on the ESP32 microcontroller with an on-off control mechanism was successfully designed using paraffin wax combined with silica sand as a thermal storage medium. The addition of silica sand significantly enhanced heat conductivity and temperature stability. Test results showed a substantial reduction in energy consumption, with daily savings reaching Rp12,762.88, equivalent to 67% of total daily energy costs. Over a one-year period, the total savings amounted to Rp4,658,103.20, demonstrating that the paraffin wax–silica sand combination is highly effective in improving energy efficiency and reducing long-term operational costs.

This study aims to examine the effectiveness of attractants on the activity of the pollinating beetle Elaeidobius kamerunicus and its impact on the efficiency of pollination and palm oil (Elaeis guineensis) production at PT Menthobi Makmur Lestari, Lamandau Regency, Central Kalimantan. The study was conducted from May to July 2025 using a factorial randomized block design with two factors: topography (flat 0–8% and hilly 15–25%) and attractant doses (0, 1, 2, and 3 ml/ha) with three replications.The parameters observed included the frequency of E. kamerunicus visits to female flowers and the percentage of fruit set. The results showed that the topography factor, attractant dose, and their interaction significantly affected the number of E. kamerunicus visits and fruit set (p < 0.01). The combination of flat land with high attractant doses resulted in the highest visits (69.04 beetles/spike) and maximum fruit set (75.11%), while the hilly land without attractants showed the lowest results (34.60 beetles/spike; 61.22%). The application of attractants increased fruit set by more than 20% compared to the control, leading to an increase in bunch weight (BJR) of approximately 5.67 kg/bunch, additional production of about 1,151 kg FFB/ha per 1.5 months, and a potential income of Rp 3,683,200/ha, far exceeding the application cost of Rp 211,638/ha. These results indicate that the use of attractants is an effective and efficient agronomic strategy to improve palm oil productivity. Thus, attractants have proven to significantly enhance pollination efficiency and palm oil production, providing substantial economic benefits to farmers and supporting the sustainability of palm oil plantations. This approach offers an applicable and sustainable solution for agricultural practices, which can be applied to various locations with similar topographical conditions.  

The purpose of this study was to gain a better understanding of how the operational budget planning process is applied to the Mebel Serba Usaha (Mebel Serba Usaha) business, which falls into the micro, small, and medium-sized business category. A quantitative descriptive approach was used, collecting data through direct interviews and observing business activities. The obtained data was then examined to determine costs. Furthermore, sales records over the past four years were evaluated for their use. The analysis revealed that Mebel Serba Usaha has never created an operational budget. This situation makes it difficult for the company to manage its finances, which ultimately impacts performance and profitability. The study shows that an operational budget is a crucial tool for more targeted financial management. Operational budget planning helps companies develop long-term business plans and organize and monitor expenses. The results of this study also emphasize that the absence of a budget tends to make companies lack a clear reference point for determining sales targets and controlling production costs. With structured budget planning, companies can more easily identify spending priorities, estimate cash flow, and assess the efficiency of resource use. Furthermore, implementing an operational budget can improve managerial discipline because every financial decision is based on careful planning, not just on immediate needs. Another benefit is increased transparency in fund management, thereby minimizing the risk of waste or misallocation of costs. Therefore, this study provides a practical contribution in the form of recommendations on the importance of implementing an operational budget for micro, small, and medium enterprises, particularly in maintaining sustainability and increasing competitiveness amidst increasingly fierce business competition.This research is expected to be a reference for other MSMEs in developing a more effective and sustainable financial system.

Sweet corn (Zea mays L. saccharata) is a high-value horticultural crop whose productivity is closely linked to effective nutrient management, particularly the balanced application of macronutrients—nitrogen (N), phosphorus (P), and potassium (K). This study evaluates the agronomic and economic impacts of applying NPK compound fertilizer at varying doses (0.5×, 0.75×, 1.0×, 1.25×, and 1.5× the recommended rate) on sweet corn growth and yield performance. Field experiments demonstrated that NPK application significantly enhanced vegetative growth parameters, including plant height, leaf number, and stem diameter, with improvements ranging from 15.8% to 37.3% over the unfertilized control. Yield components such as ear length, husked ear weight, and dehusked ear weight also showed marked increases, resulting in higher total yields per plot and per hectare. Among the treatments, the 1.25× dose achieved the highest relative agronomic effectiveness (RAE) at 147%, indicating superior nutrient utilization and biomass conversion. However, the 1.0× dose yielded the most favorable economic outcome, generating a net profit of Rp. 10,780,200 and an R/C ratio of 1.47, suggesting optimal cost-efficiency. These findings underscore the dual benefits of NPK compound fertilizer in sweet corn cultivation, highlighting that precise dosage not only maximizes agronomic performance but also enhances economic viability. The study recommends adopting the 1.0× dose for balanced productivity and profitability, while the 1.25× dose may be considered in contexts prioritizing yield maximization.

Hemoglobin examination constitutes an essential procedure in clinical diagnosis, with the SLS-hemoglobin method serving as a non-toxic alternative to cyanmethemoglobin. However, the limited availability of sulfolyser has prompted investigations into the use of soap solutions, which also contain sodium lauryl sulfate (SLS), as a potential substitute. This study employed a quasi-experimental design with a posttest-only control group on 24 blood samples, comparing the standard sulfolyser reagent with three types of commercial soaps. The analysis revealed significant differences in hemoglobin levels across groups (p < 0.001), with dishwashing soap yielding values most comparable to the control, albeit still statistically lower. These findings confirm that soap solutions are capable of lysing erythrocytes and forming hemoglobin complexes, though variations in product composition constrain the consistency of results. Practically, soap demonstrates potential as a more accessible and cost-effective alternative reagent; however, its application requires concentration standardization to ensure diagnostic validity.

Lean Six Sigma combines waste reduction principles with statistical quality control to achieve operational excellence. The research identifies major production challenges, including high defect rates, overproduction, and ineffective inventory management, all of which contribute to increased costs and reduced efficiency. The DMAIC framework—Define, Measure, Analyze, Improve, and Control—was employed to systematically address these issues. During the Define and Measure phases, types of waste were identified and defect rates were calculated using Defects Per Million Opportunities (DPMO). In the Analyze phase, root causes were examined using a Fishbone (Ishikawa) diagram, highlighting factors related to manpower, materials, machines, and methods. The analysis revealed a sigma level of 3.2, indicating a moderate level of process quality and substantial room for improvement. To address the identified issues, several improvement strategies were proposed. These include implementing a Just-In-Time (JIT) system to reduce inventory waste, adopting the First-In-First-Out (FIFO) inventory method for better material rotation, and conducting targeted technical training for operators to minimize human error. In the Control phase, the study suggests process standardization, routine inspections, and continuous monitoring as key practices to ensure that improvements are sustained over time. The findings and recommendations from this study are expected to contribute to better quality control, reduced operational waste, and enhanced productivity in the packaging printing process. Ultimately, this approach aims to strengthen PT XYZ’s competitiveness in the printing industry by fostering a culture of continuous improvement and quality excellence.

Water heating systems on ships play a crucial role in supporting crew comfort and operations. However, conventional systems generally operate continuously without automatic control, resulting in energy waste and high operational costs. This situation drives the need for innovation in more efficient and environmentally friendly water heater designs. This research aims to design and implement an automated water heater temperature control system based on an ESP32 microcontroller with on/off control and the use of paraffin wax as a latent heat storage medium. This design is expected to improve energy efficiency while reducing the operational costs of water heaters on ships. The research methodology includes system design, hardware assembly, and performance testing, both static and dynamic. Testing was conducted to evaluate temperature stability and energy efficiency in system conditions with and without the use of paraffin wax. The results showed that paraffin wax improved water temperature stability while reducing the frequency of heater activation. In a 24-hour test, the system without paraffin wax recorded a heater operating time of 15 hours, consuming 8.85 kWh of electricity and costing Rp11,965.20. In contrast, the Paraffin Wax system only requires 10 hours of heater operation, consumes 5.90 kWh, and costs Rp7,976.80. This demonstrates energy savings of 2.95 kWh and a cost efficiency of up to 58%. Therefore, the ESP32-based water heater automation system and heat storage using Paraffin Wax are proven to be more energy-efficient, cost-effective, and have the potential to be an innovative and environmentally friendly solution for ship operational needs.

This study is motivated by the downstream Teh Walini industry’s reliance on third-party logistics (3PL) services for product distribution, which restricts the company’s control over several key aspects, including logistics costs, delivery speed, routing efficiency, and product handling quality. The primary objective of this research is to analyze and compare distribution costs between outsourced logistics and self-managed delivery, and to evaluate the potential cost efficiency of an independently operated shipping system. A descriptive comparative quantitative method is employed, incorporating movement generation analysis, distribution spread mapping, and Vehicle Operating Cost (VOC) calculations to estimate the cost implications of self-shipping. Data were obtained through company documentation and analyzed using multiple linear regression involving six major distribution points. The results reveal that shipment volume significantly influences movement generation, with Waingapu, Makassar, and Padang identified as the dominant distribution destinations. The cost comparison analysis demonstrates that self-managed delivery is more cost-effective than third-party logistics services, making it a more viable long-term option. These findings suggest that transitioning to a self-delivery system could improve cost control and logistical efficiency for the company. However, this strategy should be implemented gradually, supported by regular updates on operational cost data and proactive management of external factors that could impact distribution performance. The study concludes by recommending broader coverage and the inclusion of additional relevant variables in future research to further validate and enhance decision-making related to distribution strategies. A well-informed shift toward internal logistics could ultimately contribute to greater competitiveness and sustainability in the company’s distribution operations
