Heavy equipment effectively plays a key role in ensuring productivity and efficiency in the precast concrete industry of spun pile concrete at PT Adhi Beton Purwakarta. One of the heavy equipment that plays an important role is the mobile crane, especially for moving large concrete components. In this study, field data was processed by analyzing the productivity and efficiency of the Tadano GR-500EXL type mobile crane with a capacity of 50 tons. Current problems are high idle time, lack of operational synchronization, and suboptimal utilization of technological features on the crane unit. The results show that spun pile concrete weighing 6.78 tons based on the analysis of heavy equipment productivity is 40.68 tons/hour with the number of mobile crane heavy equipment needed as many as 2 units, and the efficiency for crane heavy equipment reaches around 68%. The amount of productivity and needs are to support the target of achieving precast concrete production, especially spun pile concrete. Thus, it is expected that the amount of productivity and the number of mobile crane heavy equipment needs are optimal to support production.

Project scheduling is an important element for shipyard companies to gain more profit. The most frequently used analysis is the Critical Path Method (CPM). However, in reality, planning using the CPM method is considered less efficient because it does not consider the productivity of each job in it and adds safety time which causes the project duration to become longer. In accordance with the above problems, a new method for planning project schedules is now being developed, namely Critical Chain Project Management (CCPM). CCPM is a project planning method that emphasizes the resources needed to carry out existing tasks in the project. This method is carried out by eliminating multitasking, student syndrome, Parkinson's law and providing a buffer at the end of the project. In this final project, a comparison of the duration of the results of applying the CCPM method with the Critical Path Method (CPM) method is carried out in a case study of ship repairs at PT. Galangan Kapal Madura. The initial project scheduling uses the traditional method in the form of a Gantt chart which is then broken down in more detail and completely with the relationship between activities in the form of CPM, and then will be compared with the duration of the results of CCPM scheduling which has eliminated multitasking, eliminated Safety time for each activity and provided a buffer in the work.

Overburden removal at Pit B did not meet the production targets for June and July 2025, which were set at 570,698.8 BCM and 400,986.56 BCM, respectively, while the actual production achieved was 507,071.66 BCM and 312,128.23 BCM. This study aims to determine the theoretical productivity of loading and hauling equipment and to identify the factors that hinder the achievement of production targets. The primary data used in this study include the cycle time of loading equipment, the cycle time of hauling equipment, bucket fill factor, and delay time. The secondary data required consist of swell factor, number of passes, bucket capacity, and available working time. The productivity of the loading equipment was 332.58 BCM/hour, while the hauling equipment achieved a productivity of 53.16 BCM/hour, with a match factor of 0.74. This indicates that the loading equipment experienced waiting time during loading operations due to the hauling equipment not operating optimally or at full capacity. The factors inhibiting the achievement of production targets include a narrow, waterlogged, and uneven working face; hard overburden material; a road grade of 16%, which exceeds the standard maximum of 12%; a curve road width of 15 m, which is less than the ideal minimum width of 19.95 m; undulating haul roads; narrow haul road width; and dusty road conditions.

The transition to the remote working era has reached a point of stabilization as a fundamental structure in the 2025 global employment landscape. This systematic literature review aims to evaluate the impact of remote work on employee productivity, mental well-being, and the role of Artificial Intelligence (AI) integration. By analyzing large-scale secondary data (>10,000 participants) from various authoritative databases, the study finds that productivity experienced a net increase of 13% to 22%. The primary driver is the average commute time saving of 72 minutes per day, which is converted into productive work hours. However, findings also indicate a risk of digital burnout in 69% of respondents due to an "always-on" work culture. AI integration has assisted 65% of workers in automating administrative tasks, shifting focus toward strategic work. This research concludes that the success of remote work models requires a shift in leadership style toward trust-based management and formal policies regarding the "right to disconnect.".

Farmers are grappling with drought challenges that jeopardize rice production. To address this, the government is promoting the use of water pumps and the construction of reservoirs. However, reservoir development comes with specific stipulations, such as the land used needing to be owned by the village or government. Climate change poses a significant challenge to Indonesia's agricultural sector. The pump irrigation program has emerged as a crucial solution for water scarcity in farmlands. This research was conducted in Belangturi Village, Ruteng District, Manggarai Regency, chosen purposively due to its status as a key rice paddy development area. The study took place from December 2023 to April 2024, employing simple random sampling. Data indicates there are 40 active rice paddy farmers in Belang Turi Village. An economic analysis forecasts substantial benefits from this program, including a 20-30% increase in rice production, an improved cropping index, crop diversification, and a 40-60% rise in farmer income. The financial analysis yields highly positive results: an NPV of IDR 450,000,000, an IRR of 18%, a Payback Period of 4.5 years, and a BCR of 1.75, all strongly indicating a highly feasible investment. From a social standpoint, pump irrigation is desperately needed and enthusiastically supported by the community. It's perceived as vital for overcoming critical water shortages, enhancing welfare, and improving access to education and healthcare. Therefore, implementing this pump irrigation system is highly recommended as a comprehensive solution for sustainable agricultural development in Belang Turi Village.

This study aims to analyze production performance and the factors influencing the productivity of mining operations at PT. XYZ during August 2025. The evaluation covers production achievement against the corporate work plan (RKAP) and the owner’s operational plan, equipment availability (Physical Availability), the productivity of loading and hauling units, and various types of loss time that reduce effective working hours. The results indicate that production realization reached only 65% of the RKAP target, while achieving 102% of the owner’s plan for total material. Low equipment availability, high loss time such as no hauler, wait operator, and front preparation, as well as the underperformance of 80-ton and 100-ton units, were identified as the main contributors to production deviation. Additional influencing factors include unit reassignment, suboptimal haul road conditions, and insufficient operational fleet numbers. The study recommends optimizing fleet management, enhancing preventive and predictive maintenance programs, reorganizing hauling workflows, and controlling dominant loss time sources to improve operational efficiency and production target achievement in future periods.

This study aims to analyze the influence of emotional intelligence, work discipline, and job commitment on employee productivity at DP3AP2KB Kota Kediri. The research employed a quantitative approach with a population of 45 employees, all of whom were included as the sample using a saturated sampling technique. The research instrument was a five-point Likert-scale questionnaire tested for validity and reliability. Data were analyzed using multiple linear regression with the aid of SPSS version 25, preceded by validity, reliability, and classical assumption tests (normality, multicollinearity, and heteroscedasticity). The results indicate that emotional intelligence has a significant partial effect on employee productivity, while work discipline and job commitment show no significant effect. However, simultaneously, the three independent variables significantly affect productivity with an Adjusted R² value of 0.846. These findings highlight that emotional intelligence is the dominant factor influencing productivity, whereas work discipline and job commitment function more as basic requirements already embedded within bureaucratic systems. The practical implication of this study suggests the need for soft skill development programs, emotional management training, and the improvement of employees’ interpersonal skills to enhance productivity in the public sector.

(KO = Control), (K1 = 0.5 grams/litre of water), (K2 = 1 gram/litre of water), (K3 = 1.5 grams/litre of water), (K4 = 2 grams/litre of water), (K5 = 2.5 grams/litre of water) with 3 replications and with AB MIX concentrations, 0 to 7 days after planting = 400 ppm, 8 to 14 days after planting = 600 ppm, 15 to 21 days after planting = 800 ppm, 22 to 28 days after planting = 1000 ppm, 29 to 35 days after planting = 1200 ppm, 36 days and onwards until harvest = 1500 ppm. The variables observed in this study were plant height, leaf length, leaf width, number of leaves, and plant stem diameter. The results showed that a concentration of Gandasil D 2.5 grams/litre of water gave the best results with an average plant height of 37.93 cm, 12.56 leaves, leaf length of 24.16 cm, leaf width of 14.31 cm, stem diameter of 11.69 mm, and harvest weight of 232.89/plant. The data were analysed using analysis of variance (ANOVA) and followed by a post hoc test at a significance level of 0.05. The analysis of the feasibility of farming showed an R/C ratio of 1.03, which means that kale cultivation using a hydroponic system and the aforementioned nutrient concentration is feasible and profitable.

This study aims to analyze the effectiveness of the Hatch and Carry Center (H&C) in increasing the population of Elaeidobius kamerunicus pollinating weevils, fruit set levels, and Fresh Fruit Bunch (FFB) productivity in oil palm plantations at Division 6 Estate SGT 02, PT Kayung Agro Lestari, West Kalimantan. The research was conducted over six months, from July to December 2024, using a quasi-experimental comparative design. The period without H&C (July–December 2023) served as the control, while the period with H&C (July–December 2024) was treated as the intervention, allowing for a clearer analysis of differences before and after program implementation. Primary data were collected through monthly field observations on the number of male and female flowers, weevil populations, fruit set levels, and parthenocarpic fruits, providing consistent information on plant reproductive dynamics. In addition, in-depth interviews and Focus Group Discussions (FGDs) with stakeholders were conducted to identify supporting and inhibiting factors during implementation. Secondary data on FFB production were obtained from company harvest records in both periods to compare productivity trends. Quantitative data analysis employed the t-test to examine significant differences between the control and treatment periods, while qualitative data were thematically analyzed to explore the dynamics of program execution. The combination of both approaches is expected to provide a comprehensive understanding of the effectiveness of H&C as an innovation in oil palm pollination management.

This study aims to analyze the effect of job satisfaction and organizational commitment on employee productivity at the Semarak Dana Mojokerto Savings and Loan Cooperative.  The problem of low discipline and performance of marketing staff is an important background, given the limited empirical studies on human resource factors in micro cooperatives in Indonesia.  This study uses a quantitative approach with a total sampling technique on 35 respondents.  The instrument, in the form of a questionnaire, consisted of 28 statement items measured on a 1–5 Likert scale, with validity and reliability tests showing good results (Cronbach's Alpha > 0.70). Multiple linear regression analysis was used with the help of SPSS 26. The results of the study show that job satisfaction has a significant positive effect on productivity (β = 0.723, p < 0.05), as does organizational commitment (β = 0.555, p < 0.05). Simultaneously, these two variables contribute to an increase in employee productivity with a coefficient of determination of 77.8%.  These findings support the theories of Locke (1976) and Meyer & Allen (1991) and are in line with previous studies, although the context of micro cooperatives provides unique characteristics. The practical implications of this study encourage cooperatives to strengthen their reward systems, provide training, and improve work SOPs, particularly in marketing services. The limitations of this study lie in the small sample size and cross-sectional design. Future research is recommended to use a larger sample, a longitudinal approach, and include moderator variables such as work motivation or organizational culture.

The results demonstrate a positive relationship between motivation and employee work productivity at the Wajo Intellectual Mandiri Job Training Institute in Wajo Regency. This study highlights the importance of motivation in enhancing work productivity and provides valuable insights for improving organizational performance by fostering motivation among employees. The findings can be used as a basis for developing strategies to optimize employee productivity in similar organizational settings. 

In manufacturing industries, machining processes play a critical role in ensuring product quality, precision, and production efficiency. However, in the production of swing arm parts, the machining process has been identified as a bottleneck due to its non-optimal cycle time. One of the main issues contributing to this inefficiency is the disorganized handling of circlip inner parts. These components are often scattered without a designated placement system, which creates significant difficulties for operators when retrieving and installing circlips onto the swing arm. Such abnormalities disrupt workflow continuity, extend production time, and reduce overall productivity. To address this challenge, a circlip feeder machine was designed as a supporting device to assist operators and streamline the machining process. The design emphasizes efficiency, integration, and systematic operation by utilizing readily available workshop materials. The developed feeder machine is equipped with a robust frame construction and has a storage dimension capable of accommodating up to 200 circlips. In addition, mechanical analysis demonstrates that the feeder structure can withstand a maximum applied force of 31,475 N, ensuring durability and reliability during operation. The introduction of this circlip feeder machine directly impacts the production process by reducing operator workload, minimizing delays caused by disorganized parts, and ensuring faster and more accurate installation of circlips. Consequently, the overall machining cycle time is shortened, thereby improving production flow and enhancing the efficiency of swing arm part manufacturing. Beyond immediate time savings, the use of the feeder machine contributes to better resource utilization, reduced ergonomic strain on operators, and improved consistency in product quality. This study highlights the significance of simple yet effective mechanical innovations in overcoming production bottlenecks and optimizing manufacturing processes in automotive component industries.

The community service program in Kemiri Village aims to empower farmers through the use of local potential, especially moringa leaves (Moringa oleifera), as raw materials for liquid organic fertilizer (POC). This activity was carried out with a participatory and educational approach that directly involved farmer groups in technical training on making POC through simple fermentation methods using natural ingredients such as moringa leaves, rice washing water, organic waste, and local decomposers. Through this activity, farmers are taught stages ranging from the collection of ingredients, the process of shredding moringa leaves, mixing with complementary ingredients, to the correct fermentation techniques to produce high-quality fertilizer. The training is carried out by field demonstration methods, discussions, and hands-on practice, so that farmers not only gain theoretical knowledge, but also practical skills that can be applied independently. The results show a significant increase in farmers' knowledge, skills, and awareness of the importance of liquid organic fertilizer as an environmentally friendly alternative. In addition, the public's enthusiasm is getting higher after seeing real evidence that the use of POC moringa leaves is able to increase plant growth, crop quality, and reduce dependence on chemical fertilizers which are increasingly expensive and have the potential to damage the soil. This program not only provides economic benefits through the cost efficiency of agricultural production, but also has a positive impact on environmental conservation. This activity is expected to be a model of community empowerment based on local potential that can be replicated in other regions with similar conditions. The success of the program shows that simple innovations that utilize local resources, if managed well, can support sustainable agriculture and food security for rural communities.
