The factors influencing lowland rice production in Padang City are the focus of this study. The study was conducted through a field survey of lowland rice farmers to obtain primary data relevant to farming activities. The analysis method used was multiple linear regression with the dependent variable being lowland rice production (Y) and independent variables including land area (X₁), seeds (X₂), fertilizer (X₃), labor (X₄), and farming experience (X₅). The research findings show that simultaneously all production factors, including land area, seeds, fertilizer, labor, and farming experience, have a significant effect on lowland rice production in Padang City. Partially, the variables of fertilizer and labor have a significant effect on lowland rice production, while land area, seeds, and farming experience have no significant effect. These findings indicate that the increase in lowland rice production in Padang City is more determined by input intensification efforts, particularly through appropriate fertilization and labor availability, compared to land expansion. As a result, agricultural policies need to be directed at increasing input efficiency to support the productivity and sustainability of rice farming.

The era of globalization demands that education systems produce human resources who are skilled, adaptable, and capable of competing in the international job market. However, several issues arise in efforts to prepare graduates who are well aligned with industry requirements. These challenges include the mismatch between competencies taught in educational institutions and those required by the workforce, limited digital literacy and technological mastery, the lack of soft skills development, and insufficient collaboration between schools and industries. Rapid technological advancements often result in curricula that lag behind the current skill demands of the labor market. Moreover, many students still lack the mindset, creativity, and adaptability needed to face global competition. This literature-based study aims to identify the main educational problems in preparing human resources for the world of work and propose strategic directions for improvement. Findings highlight the necessity of competency-based curriculum transformation, enhanced vocational training, integration of technology-based learning, and stronger partnerships between education providers and industry sectors. Enhancing teacher quality is also crucial to ensure learning processes remain relevant to global demands. By optimizing the roles of all stakeholders, education can produce graduates who possess not only technical expertise but also essential 21st-century skills such as communication, collaboration, problem-solving, and leadership. Therefore, education becomes the primary foundation for preparing a generation capable of competing globally and contributing to national development.

Modern education has produced various learning theories such as behaviorism, cognitivism, humanism, constructivism, and postmodernism, each contributing significantly to the understanding of learning processes, motivation, and knowledge formation. However, these theories are rooted in secular philosophical foundations that place humanity at the center of truth while neglecting the spiritual dimension revealed in Scripture. This condition creates tension for Christian education, which upholds the Bible as the epistemological basis and ultimate purpose of learning. This study aims to critically examine the secular assumptions embedded within modern learning theories, identify pedagogical elements that can be integrated into Christian education, and formulate strategies for Christian educators to utilize secular theories without compromising their theological foundation. The research employs a descriptive qualitative method through a literature review of books, journals, and relevant academic sources. The findings indicate that although modern learning theories offer valuable pedagogical insights, they contain naturalistic, rationalistic, humanistic, and relativistic assumptions that must be filtered through biblical theology. Christian educators are not required to reject secular theories entirely; rather, they bear an apologetic responsibility to discern useful methods, reject conflicting philosophical assumptions, and direct the entire learning process toward glorifying God. Thus, modern learning theories can function as effective tools within Christian education when positioned correctly as pedagogical instruments under the authority of Scripture.

Red blood cells are essential for carrying oxygen and vital nutrients needed for the growth of the fetus, therefore anemia during pregnancy is a complex issue. It is vital for all expectant mothers to fulfill their iron needs because maternal anemia during pregnancy can result in adverse consequences for the child, such as premature birth and low birth weight. The chance of a woman developing anemia increases as she ages during pregnancy. Bleeding is a direct result of the anemia experienced during labor in 17.24% of cases.

The research method used is a quantitative method where the data from laboratory tests on coal quality before and after spontaneous combustionis analyzed, the comparison of coal quality in stockpile 10 before and after spontaneous combustionis then graphed to see changes in the quality of each parameter. Based on the results of the analysis of changes in coal quality before and after spontaneous combustion, there were significant changes to several coal quality parameters, namely Total Moisture which was originally from 7.06% to 5.50% (down by 1.56%), Moisture which was originally 3.91% to 3.22% (down by 0.69%), Ash Content which was originally 8.84% to 14.67% (up by 5.83%), Volatile Matter which was originally 39.77% to 35.10% (down by 4.67%),  Fixed Carbon from 47.48% to 47.01% (down by 0.47%), Sulphur from 0.55% to 0.46% (down by 0.9%), and Calorific value decreased from 6,921 to 6,289 kcal/kg (down by 632 kcal/kg). This decrease in quality has a direct effect on the selling value and efficiency of coal combustion. The existence of an analysis of changes in coal quality due to spontaneous combustioncan help companies to find out how much of an impact losses can be caused by the occurrence of spontaneous combustion. By considering the potential losses due to spontaneous combustion, the company will make efforts to prevent the occurrence of spontaneous combustion in the future to minimize the losses caused.

Premature rupture of membranes (KPD) is the rupture of the membranes before there are signs of labor, and after waiting for an hour the signs of labor have not yet begun. The time from when the membranes rupture until uterine contractions occur is called premature rupture of membranes. Factors that are closely related to PROM include infection, socio-economic factors, blood type factors, smoking behavior, history of PROM, incompetent cervix and intrauterine enhancement that is high or excessively high, fetal disproportion, multigravidity, multiple pregnancies, previous history of PROM , polyhydramnios, trauma, age and parity. The danger of premature rupture of membranes is the possibility of infection in the uterus and premature birth which can increase morbidity and mortality for mother and baby. Premature rupture of membranes causes a direct connection between the outside world and the space in the uterus, making it easier for infection to occur. The aim of this study is to determine the relationship between age and parity with the incidence of premature rupture of membranes in women giving birth at Harapan Bunda Hospital, Batam City in 2023. This research design uses analytical observational with a cross sectional approach, where data is taken using secondary data with a sample size of 65 people. The processing technique uses the chi-square test. The data obtained from the results of statistical tests is with p-value for age = 0.028 and for parity p-value = 0.039. The conclusion of this research is that the majority of mothers give birth at a non-risk age (20-35) and at a parity that is not at risk (2-3). There is a relationship between the age and parity of mothers giving birth and the incidence of KPD at Harapan Bunda Hospital, Batam City in 2023. With the p-value is 0.028 for age and the p-value is 0.039 for parity so that the p-value < α (0.05).

The production process is a crucial aspect in ink formulation, especially violet spot color inks for gravure printing applications, which cannot be accurately reproduced through conventional process printing systems (CMYK). This research aims to optimize the production parameters of violet gravure inks that often exhibit color instability due to delays in the grinding and adjusting stages. The main focus of this research is to analyze the effect of variations in grinding duration, post-grinding aging time, and the amount of raw material on ink color yield, which is evaluated based on density, CIE Lab*, and ΔE parameters. The methodology used was a descriptive experiment on a laboratory scale. The results showed that the optimal treatment combination of grinding for 90 minutes, aging for 48 hours, and the use of 400 grams of material (P3K2L4) produced the highest density value (1.858) and ΔE (0.572), indicating color stability despite quantity variations. This finding indicates that optimization of grinding and aging time contributes to the improvement of pigment dispersion homogeneity and thermal stability of the resin, even without direct measurement of the transition glass temperature (Tg) value.
