is data from laboratory tests on 23 samples of Run Of Mine (ROM) coal at seam 16 at PT Unggul Nusantara, North Barito Regency, Central Kalimantan. Data analysis was performed statistically using the help of SPSS software through Pearson correlation test and multiple linear regression analysis. The results of the correlation test showed that simultaneously, the TM, ASH, and TS parameters had a very strong relationship with the GCV value with a correlation coefficient (R) of 0.893 and contributed an influence of 76.5%. Partially, Ash Content (ASH) had a very strong negative relationship (r = -0.881) and had a significant effect on calorie values (p = 0.000). Each 1% increase in ash content would decrease the GCV value by 68.249 Kcal/Kg. Meanwhile, Total Moisture had a significant positive relationship by simple correlation (r = 0.506, p = 0.014), but showed no partial significant effect in multiple regression models (p = 0.364). Total Sulfur was found to have a very weak negative relationship (r = -0.182) and had no significant effect on GCV values (p = 0.406). This study concludes that Ash Content is the most dominant parameter that affects the reduction of the caloric value of coal seam 16 at PT Unggul Nusantara.

s, ranging from 85-90%, as well as dependence on unstable imported raw materials. The research method used is quantitative descriptive with purposive sampling techniques on the company's consolidated financial statements. The indicators used to analyse the data include Gross Profit Margin (GPM), Net Profit Margin (NPM), Return on Assets (ROA), and Return on Equity (ROE). In 2022, net profit fell sharply by 57% to RP 27 billion due to production cost pressures. However, in 2024, the company managed to recover with a net profit of RP 489.8 billion. This unique finding shows an increase in Return on Assets (ROA) of 9.10% in 2024 despite a decline in assets. This shows that management has succeeded in eliminating unproductive assets and optimising production efficiency. The effectiveness of cost transformation and the company's operational resilience to market fluctuations are reflected in a Return on Equity (ROE) of 18.61% at the end of the period.

o local elementary school teachers and also the results of researchers' observations over the years, there are differences in the development of both academic and non-academic elementary school students between areas adjacent to the sea and those that are not. including in his gross motor development. Motor development is very necessary for children's development, especially in school. gross motor is a skill that requires coordination of a large part of the child's body. Based on the above opinion, it is concluded that gross motor is a physical movement activity that requires coordination of the limbs by using their large muscles. Students who have good motor skills are able to do sports skills than students who have fission skills. From the explanation above, the researcher wants to conduct research on the Gross Motor Ability Profile of students, where this is the main focus because Gross Motor Skills is very important to be mastered by a person because he can do daily activities, without having good movements he will lag behind others, such as: running, jumping, pushing, throwing, catching, kicking and so on, these activities require and use large muscles in a person's body
Abstract:This study aims to examine the effect of volleyball learning on students’ gross motor development, which constitutes a crucial aspect in supporting adolescents’ physical fitness and movement skills. The research problem…
lem arises from the low level of students’ gross motor abilities, as indicated by weak coordination, agility, balance, and muscle strength, resulting from limited structured physical activity and the dominance of conventional teaching approaches. A quantitative approach was employed using a quasi-experimental pretest–posttest control group design to evaluate the effectiveness of systematically designed volleyball instruction. The findings reveal a significant improvement in the experimental group, with the mean score increasing from 64.28 to 78.45, while the control group showed only a modest increase from 63.91 to 68.12. Statistical analysis indicates a significant difference with a t-value of 6.214 and a significance level of 0.000, supported by an effect size of 1.28, which falls into the large category. These results confirm that volleyball-based learning is effective in enhancing overall gross motor skills through structured and varied movement activities. The novelty of this study lies in its comprehensive approach that integrates multiple motor components within a unified analytical framework, as well as the use of effect size to strengthen the practical significance of the findings. This study provides a meaningful contribution to the development of more innovative, interactive, and movement-based physical education learning models to optimize students’ motor development sustainably.

imating GRDP using integration of satellite imagery and official statistics data can provide valuable information. This research estimates the GRDP value in 2022 by using data in 2019 to 2021 related to two aspects, agriculture and non-agriculture. Soil adjusted vegetation index (SAVI), enhanced vegetation index (EVI), and land cover (LC) used as agriculture aspect, while nighttime light (NTL), human settlement index (HSI), land area, and population per regency/city used as non-agriculture aspect. GRDP estimation are produced with machine learning approach using support vector machine (SVM) and random forest (RF) method. Correlation test on each variable shows only land area that does not have a significant correlation with GRDP. RF model then chosen as the best model with RMSE, MSE, MAE, and R2 value of 0.2549; 0.5049; 0.7727; and 0.2543, respectively. The estimated values acquired in several regencies/cities have rather near, some even very close to the official statistics values.

Abstrak: Produk Domestik Regional Bruto (PDRB) merupakan salah satu indikator sosio-ekonomi yang penting. Penghitungan nilai PDRB dengan pendekatan yang melibatkan kombinasi data citra satelit dan statistik resmi dapat memberikan informasi serta pemahaman yang lebih komprehensif. Penelitian ini melakukan estimasi nilai PDRB pada tahun 2022 menggunakan data tahun 2019 hingga 2021 dengan melibatkan dua aspek, agrikultur dan non-agrikultur. Data soil adjusted vegetation index (SAVI), enhanced vegetation index (EVI), dan tutupan lahan (land cover/LC) digunakan sebagai aspek agrikultur, sementara data citra cahaya malam (NTL), human settlement indeks (HSI), luas wilayah kabupaten/kota, dan jumlah populasi per kabupaten/kota digunakan sebagai aspek non-agrikultur. Estimasi PDRB dihasilkan dengan menggunakan pendekatan machine learning berupa support vector machine (SVM) dan random forest (RF). Pengecekan korelasi antarvariabel menunjukkan bahwa hanya variabel luas wilayah tidak berpengaruh signifikan terhadap nilai PDRB. Model random forest kemudian dipilih sebagai model terbaik dengan nilai evaluasi RMSE, MSE, MAE, dan berturut-turut sebesar 0.2549, 0.5049, 0.7727, dan 0.2543. Nilai estimasi yang diperoleh di beberapa kabupaten/kota cukup mendekati, bahkan ada yang sangat dekat dengan nilai statistik resmi.

planatory design using secondary time-series data obtained from Statistics Indonesia (BPS) of East Kalimantan. Path analysis was applied through two structural equations using SPSS 21, complemented by the Sobel test to examine the mediating role of GRDP. The results show that population and investment each have a positive and significant direct effect on GRDP, and jointly explain 97.4% of its variation. GRDP, in turn, has a negative and significant effect on unemployment, accounting for 76.3% of its variation. The Sobel test confirms that GRDP significantly mediates the indirect effects of both population (Z = 2.295) and investment (Z = 2.628) on unemployment. These findings indicate that economic growth, as reflected in GRDP, acts as a strategic transmission channel converting demographic potential and capital accumulation into employment opportunities, thereby reducing unemployment in the region.
