This study aims to determine the effect of triangle pass and square pass training on passing accuracy among female futsal extracurricular participants at SMA Negeri 1 Cisaat. This study employed a quantitative method with a two-group pretest–posttest experimental design. The sample was divided into two groups: one group received triangle pass training, while the other group received square pass training. Data were collected through passing accuracy tests conducted before (pretest) and after (posttest) the treatment. The data were analyzed using paired sample t-tests and independent sample t-tests. The results showed that there was an improvement in passing accuracy in both groups. The triangle pass group increased its mean score from 62.40 to 78.20, while the square pass group improved from 61.80 to 73.50. Statistical analysis indicated that both training methods had a significant effect on passing accuracy (p < 0.05). Furthermore, there was a difference in effectiveness between the two methods, with triangle pass training being more effective than square pass training. In conclusion, both triangle pass and square pass training significantly improve passing accuracy; however, triangle pass training is more recommended as the primary method in futsal training programs.

Kebijakan kesejahteraan sosial merupakan instrumen strategis pemerintah dalam meningkatkan taraf hidup masyarakat serta mengurangi kesenjangan sosial melalui distribusi bantuan publik. Namun demikian, dalam praktik implementasinya di tingkat lokal, kebijakan ini kerap menghadapi berbagai persoalan, terutama terkait ketepatan sasaran, transparansi, dan keadilan distribusi bantuan. Fenomena tersebut juga terlihat di Desa Ladogahar, Kecamatan Nita, Kabupaten Sikka, di mana masih ditemukan indikasi ketimpangan dalam penyaluran bantuan kepada masyarakat. Penelitian ini bertujuan untuk menganalisis implementasi kebijakan kesejahteraan sosial dan ketimpangan distribusi bantuan publik dengan menggunakan tinjauan teori keadilan, khususnya keadilan distributif. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi pustaka dan penelitian lapangan. Data diperoleh melalui observasi, wawancara mendalam dengan aparat desa dan masyarakat penerima bantuan, serta dokumentasi terkait kebijakan yang berlaku. Hasil penelitian menunjukkan bahwa implementasi kebijakan kesejahteraan sosial di Desa Ladogahar belum sepenuhnya berjalan secara optimal, ditandai oleh lemahnya validitas data penerima, adanya pengaruh kedekatan sosial dalam penentuan penerima manfaat, serta kurangnya transparansi dalam proses distribusi. Dalam perspektif teori keadilan, kondisi ini mencerminkan belum terpenuhinya prinsip keadilan distributif yang menekankan pemerataan dan keberpihakan kepada kelompok masyarakat yang paling membutuhkan. Oleh karena itu, diperlukan upaya perbaikan melalui peningkatan akuntabilitas, transparansi, dan partisipasi masyarakat guna mewujudkan distribusi bantuan publik yang lebih adil dan merata.

The stock market is a place to buy shares for profit. In Indonesia, energy stocks are highly unpredictable because global commodity prices change constantly. This study examines what affected energy stock returns in 2024, focusing on trading volume, price swings, company profits, and cash flow. Using financial reports and statistical analysis, all these factors were tested together and individually. The results show that combined, all these factors do affect stock returns. However, when looked at one by one, only the company's net profit truly matters to investors. On the other hand, busy trading, daily price swings, and cash flow have no impact at all. In fact, all the factors studied only account for 14% of stock return movements, while the remaining 86% is driven by other outside forces. In conclusion, for those looking to invest in energy stocks, the most important thing to watch is the company's ability to generate net profit, rather than just looking at how busy daily transactions are in the market.

Pressure sensitive labels (PSLs) made of polyethylene (PE) white are widely used in the packaging industry due to their flexibility, moisture resistance, and ease of application on various substrates. This study aimed to examine the effect of glossy and matte lamination on the tensile strength and color difference (ΔE) of PE white PSLs. An experimental method was employed, with tensile testing conducted using a universal testing machine (UTM) in accordance with ASTM standards and color measurement performed using a spectrodensitometer based on the CIE Lab system. The samples were divided into three treatment groups, namely no lamination, glossy lamination, and matte lamination, with ink coverage controlled at two design conditions, full ink and minim ink. The results indicated that lamination type significantly affected both the mechanical and visual characteristics of the labels. In the tensile strength test, the highest mean value was obtained by one treatment group, indicating superior resistance to tensile loading. In terms of color stability, higher ΔE values indicated greater color change and lower lightfastness, whereas lower ΔE values reflected better color retention. Overall, the findings show that the combination of lamination type and ink coverage influences the performance of PE white PSLs in both mechanical strength and color stability.

This study analyzes the effect of logistics digitalization systems and personnel competence on the distribution of personnel uniforms (kaporlap) at Kodiklatal. The study was motivated by the fact that the distribution system had not yet operated optimally despite the implementation of digital logistics, while delays in updating the Sistem Informasi Entitas Samapta (SIMBENSAM), limited documentation of device identities, and unequal digital skills among personnel still constrained distribution performance. A quantitative approach with explanatory design was applied. The population consisted of 3,099 personnel and the sample comprised 97 respondents selected using Slovin's formula. Data were collected through Likert-scale questionnaires and internal documentation, then analyzed using validity and reliability tests, classical assumption tests, descriptive analysis, and simple and multiple linear regression. The results show that the logistics digitalization system has a positive and significant effect on kaporlap distribution (t = 24.607; p < 0.05), personnel competence also has a positive and significant effect (t = 37.972; p < 0.05), and both variables simultaneously affect distribution performance (F = 788.285; p < 0.05) with an R square of 0.944. These findings confirm that digital systems and human competence must be strengthened in an integrated manner to support efficient, accurate, and timely distribution in a military education environment.

This study aimed to analyze the influence of workload and burnout on nurses’ sleep quality while controlling for age, gender, and education as potential confounding variables. A quantitative analytic study with a cross-sectional design was conducted among 156 nurses working in a private hospital in Depok City. Data were collected using a workload questionnaire, the Maslach Burnout Inventory (MBI), and the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using Chi-Square tests and multiple logistic regression. The findings showed that both workload and burnout had significant effects on sleep quality (p < 0.05), with burnout identified as the most dominant factor. Age and gender were also significantly associated with sleep quality, whereas education did not show a statistically significant effect. The regression model demonstrated excellent fit, indicated by a McFadden pseudo R² value of 0.908. These results suggest that occupational factors, particularly burnout, play an important role in determining nurses’ sleep quality. Therefore, effective stress reduction and workload management strategies are needed to support nurses’ well-being and improve sleep quality.

The risk of accidents in the school environment is quite high, but the ability of the School Health Business Team (UKS) to handle emergencies is often still limited to theoretical knowledge without adequate practical skills. This study aims to analyze the influence of the Role Playing and Emergency Simulation (RANGGA) method on the improvement of the knowledge and skills of the UKS Team in junior high school. This study used a quasi-experiment design with a pre-post test with control group design. The research sample amounted to 60 respondents which were taken by purposive sampling technique. The intervention group was given RANGGA training, while the control group was given conventional education. The data were analyzed using the non-parametric Wilcoxon Signed Ranks Test because the data distribution was abnormal. In the intervention group, there was an increase in the average knowledge score from 88.7 to 97.9 and the skill score from 87.99 to 97.98. The results of the Wilcoxon test showed a significance value of p<0.001 for both variables in the intervention group, indicating a very strong influence of the RANGGA method. In contrast, although the control group experienced an improvement, the variation in scores remained higher and the improvement was not as significant as the intervention group. The RANGGA method is significantly effective in improving the emergency competence of the UKS Team through an experiential learning approach. It is recommended for school institutions to integrate simulation and role play methods in the UKS training curriculum to ensure optimal emergency response readiness.

Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.
