The stability of disposal slopes is a critical aspect of open-pit mining operations because it directly affects operational safety and the continuity of overburden dumping activities. Disposal areas composed of overburden materials generally exhibit heterogeneous characteristics, particularly when soft materials such as mud are present, which can significantly reduce slope stability. Therefore, a comprehensive slope stability evaluation is required prior to further disposal development. This study aims to assess the stability condition of a disposal slope under initial conditions, evaluate the influence of material conditions, and analyze the effectiveness of counterweight application in improving both the safety factor and disposal capacity. The research methodology involved the collection of primary and secondary data, including slope geometry, lithological conditions, and the physical and mechanical properties of disposal materials obtained from laboratory testing and company technical data. Slope stability analysis was performed using the limit equilibrium method with the assistance of geotechnical software, taking into account groundwater conditions and operational loading. The analysis results indicate that the initial disposal condition yielded a safety factor of 0.718, indicating an unstable slope condition. After simulating the removal of mud material, the safety factor increased to 0.907 but remained below acceptable stability criteria. The application of a counterweight significantly improved slope stability, resulting in a safety factor of 1.498. Further optimization through slope geometry redesign produced a final safety factor of 1.101, which satisfies the requirements stipulated in KEPMEN ESDM No. 1827 K/30/MEM/2018. Additionally, the redesign increased the disposal capacity from 119,507,864.23 LCM to 119,682,378.22 LCM, representing an increase of 174,513.99 LCM. These results demonstrate that counterweight application combined with geometric optimization is effective in enhancing both slope stability and disposal capacity.

Crackers are snacks that are popular with various age groups, but generally have a relatively low calcium content so they do not contribute to meeting daily mineral needs. Therefore, food product innovations are needed to increase their nutritional value, one of which is by utilizing purebred chicken egg shells as a natural source of calcium. This study aims to analyze the effect of purebred chicken eggshell flour substitution on the acceptability of crackers and determine the best formulation as a high-calcium snack. The research method used an experimental design with a Complete Random Design (RAL) consisting of four treatments, namely P0 (100:0), P1 (90:10), P2 (85:15), and P3 (80:20). The testing is carried out qualitatively through organoleptic tests which include color, aroma, taste, and texture. The data was analyzed using the one-way ANOVA test and followed by the Post Hoc Kruskal-Wallis test if there were significant differences. The results showed that the best formulation was found in the P1 treatment with a 10% substitution of eggshell flour. Overall, the substitution of purebred chicken eggshell flour had no significant effect on the acceptability of crackers.

International student enrollment is a critical driver of financial sustainability for Higher Education Institutions (HEIs). While advanced forecasting is standard in the corporate sector, its application in educational planning remains limited. This study addresses this gap by comparing the predictive performance of ARIMA, Facebook Prophet, and Long Short-Term Memory (LSTM) models. Using a publicly available annual dataset from a US-based institution (2000–2022), the analysis employed a strategic partition training on 2000–2017 and testing on 2018–2019 to validate models on stable, pre-pandemic data. Empirical results revealed that the statistical ARIMA (2,1,0) model demonstrated superior accuracy, achieving a Mean Absolute Percentage Error (MAPE) of 1.26%. Conversely, Prophet (11.81%) and LSTM (13.84%) struggled with the limited sample size, failing to generalize effectively compared to the linear approach. The findings suggest that for annual enrollment trends, parsimonious statistical models outperform complex deep learning architectures, providing administrators with a robust, accessible framework for data-driven strategic decision-making.

The interactive learning video innovation "Human Blood Circulation" through Edpuzzle, with embedded questions, is designed to address the difficulties faced by fifth-grade elementary school students in understanding abstract biological concepts. Science education in elementary schools often encounters challenges in explaining invisible processes, such as the heart's working mechanism and blood circulation, leading students to struggle with comprehension or merely memorize the material. Conventional learning videos tend to make students passive, necessitating media that can transform the learning process into an active one. Edpuzzle, as an educational platform, allows teachers to insert questions at critical points in the video, requiring students to answer before continuing to watch. This innovation aligns with the cognitive development stage of fifth-grade students, who are in the concrete operational stage.The research objectives include product development, validity and feasibility testing, analysis of conceptual understanding improvement, influence on focus and learning independence, and student responses. Media development refers to Mayer's cognitive theory of multimedia and the characteristics of interactive videos according to Heinich et al. Additionally, media development models such as ADDIE and Dick and Carey are discussed. The main benefits of using Edpuzzle include increasing engagement, facilitating real-time formative assessment, and enhancing learning motivation. However, challenges exist such as technology access, teacher readiness, the risk of technology dependency, and long-term evaluation. The practical implications can support digital learning and the transformation of elementary science education.

PT UVW uses jigs in the vacuum metalizing process that require washing, which is currently done manually, resulting in inefficiency and risks to operators, thus, jig washer machine was created in order to reduce the risk for operators and increasing efficiency, which based on horizontal mixer. This study analyses the effect of agitator design on fluid flow patterns in a jig washing machine to obtain an optimal design. Two agitator design alternatives were developed and tested using Computational Fluid Dynamics (CFD) simulations at rotational speeds of 70, 75, and 100 rpm, followed by prototype fabrication and performance testing. Simulation results show that the second design produces a higher fluid velocity (20.4 m/s) and a more turbulent and uniform flow pattern compared to the first design (1.7 m/s). Field tests confirmed that the second design achieves higher washing effectiveness (97.14%) with reduced water consumption and shorter washing time. The optimally designed agitator washing machine increases productivity by six times compared to manual washing and reduces operator exposure to hazardous chemicals. This study recommends the second agitator design for improving washing efficiency and effectiveness.

This study aims to analyze the effects of work motivation and career development on nurses’ performance through job satisfaction among nurses at Pertamina Balikpapan Hospital. Nurses’ performance is a key determinant of service quality and patient safety because nurses interact most intensively with patients and ensure continuity of nursing care. However, prior studies on the relationships among motivation, career development, job satisfaction, and performance have reported mixed findings. Therefore, further examination is needed by incorporating job satisfaction as a mediating variable to explain the mechanism of influence more comprehensively. This research employed an explanatory design with a quantitative approach. Primary data were collected using a Likert-scale questionnaire distributed to 165 permanent nurses selected through purposive sampling from a population of 292 nurses. Data were analyzed using variance-based SEM with SmartPLS 4, including outer model evaluation (convergent and discriminant validity) and construct reliability, as well as inner model assessment through the coefficient of determination, effect size, and hypothesis testing using bootstrapping. The results indicate that work motivation has a positive and significant effect on job satisfaction, and career development also has a positive and significant effect on job satisfaction. Job satisfaction has a positive and significant effect on nurses’ performance. In addition, work motivation and career development have positive and significant direct effects on nurses’ performance. Indirect effect testing confirms that job satisfaction mediates the relationship between work motivation and nurses’ performance and also mediates the relationship between career development and nurses’ performance. These findings emphasize that hospitals should strengthen strategies to enhance motivation and career development in a targeted manner while ensuring key sources of job satisfaction so that nurses’ performance improves sustainably.

The development of education in the digital era requires students to master not only academic skills, but also soft skills and hard skills as a provision to face the challenges of education and the world of work. However, the learning process at Papua High School in Sorong City is still teacher-oriented, so students' communication courage and technological skills have not developed optimally. This community service activity aims to empower students through public communication training (public speaking) and computer network cable techniques to strengthen 21st century skills. The method used is a participatory approach with hands-on practice through four stages: observation, socialization, training, and evaluation. Public speaking training is focused on increasing students' courage and confidence in communicating, while network cable training emphasizes basic technical skills such as recognizing cable types, RJ-45 connector functions, crimping techniques, and connectivity testing. The results of the activities showed high participation and enthusiasm from students, as well as increased public speaking courage and basic understanding in network cable making. The integration of public communication training and technology skills has been proven to have a positive impact on the development of student competencies. Therefore, this activity is recommended as a model for developing soft skills and hard skills for high school students, especially in areas with limited access to technology learning.

Clean water quality is an important factor in supporting public health. In Kaliwader Village, Bener District, Purworejo Regency, drilled well water is used as the main source of clean water, however, based on initial testing, discrepancies were still found in several water quality parameters, particularly turbidity. The Community Service Lecture (KPM) activity of the Al-Qur'an Science University (UNSIQ) aims to improve the quality of drilled well water through the implementation of a water filtration system combined with a venturi aerator and providing education to the community about clean water management. The method used is a descriptive method with an observational approach, including water sampling, laboratory testing at the Regional Health Laboratory UPT, and the implementation of a Malang sand-based filtration unit with venturi aeration. The test results showed that the water turbidity level before treatment reached 8 NTU, exceeding the established quality standards. After the implementation of the filtration system and venturi aerator, the physical quality of the water improved, marked by a decrease in turbidity and an increase in water clarity. Chemical and microbiological parameters were generally within safe limits according to the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. This activity demonstrated that the application of simple technology by UNSIQ KPM students can play an effective role in improving the quality of drilled well water and supporting the provision of more adequate clean water for the people of Kaliwader Village.

Prolactinoma is the most common functional pituitary adenoma, particularly in adolescent females, and is typically characterized by amenorrhea and galactorrhea resulting from hyperprolactinemia. However, in certain cases, serum prolactin levels may appear normal due to the hook effect, an immunoassay measurement error caused by extremely high prolactin concentrations that interfere with antigen–antibody complex formation. We report the case of a 17-year-old female presenting with a five-month history of galactorrhea, accompanied by breast pain, headache, and primary amenorrhea. Brain MRI revealed a pituitary mass measuring 1.4 × 0.8 × 0.5 cm, suspicious for prolactinoma, while serum prolactin was within the normal range (17.33 ng/mL). The discrepancy between clinical manifestations, lesion size, and laboratory findings raised suspicion of the hook effect. The patient was treated with dopamine agonists, bromocriptine and cabergoline, and referred for multidisciplinary management involving endocrinology, neurosurgery, and obstetrics–gynecology. Despite the absence of prolactin dilution testing, MRI findings supported the diagnosis of prolactinoma, and the patient demonstrated a favorable clinical response to therapy. This case highlights the importance of recognizing laboratory variability, performing comprehensive hormonal evaluation, and considering prolactin dilution assays when clinical and laboratory findings are discordant, particularly in adolescent patients with suggestive symptoms.

This study investigates biomass-derived surface engineering of AISI 1020 steel for electromedical applications using galam wood charcoal and chicken bone waste as carburizing media. Surface modification is required to improve the mechanical performance of low-carbon steel, particularly in applications that demand high wear resistance and long-term durability. A pack carburizing approach was applied using various ratios of biomass-derived media at a treatment temperature of 800 °C for 2 hours. Chemical composition was analyzed using Optical Emission Spectroscopy (OES), surface hardness was evaluated using Micro Vickers hardness testing, and microstructural characteristics were observed using optical microscopy. The results show a significant increase in surface carbon content with increasing fractions of chicken bone powder, indicating its effectiveness as a carbon donor and diffusion promoter. The surface hardness increased from approximately 150 HV in the untreated condition to a maximum of about 860 HV in the treated specimen. Microstructural observations revealed the formation of a distinct carburized layer with increasing thickness and uniformity, consistent with enhanced carbon diffusion and surface strengthening. These findings demonstrate that biomass-derived surface engineering provides an effective and sustainable approach for improving the surface properties of low-carbon steel. The proposed method offers strong potential for environmentally friendly manufacturing of durable and reliable electromedical components.
