Project Conversion of Electrostatic Precipitator (ESP) Raw Mill To Bag House Filter (BHF) Indrarung IV PT. Semen Padang
No full textThe cement industry is one of the largest contributors to air pollution due to its high level of energy consumption. Emissions from cement factories contain chemicals that are harmful to health and the environment. Electrostatic Precipitator (ESP) is a dust collector commonly used in cement factories. As a result of the lifetime of the equipment being more than 30 years, the reliability of the ESP for collecting dust has decreased. In normal operation, ESP emits stack emissions ± 40 mg/Nm3 and can reach more than 60 mg/Nm3 under abnormal conditions.To reduce the impact of emissions on the environment, reduction efforts are needed so that dust emissions in chimneys according emission standards, both during normal and abnormal operating conditions. To overcome the limitations of ESP performance, conversion to Bag House Filter (BHF) was carried out. After the conversion was carried out, the emission level that came out of the chimney was 9 mg/Nm3. With BHF's high ability and efficiency in collecting dust, chimney emissions can be reduced by 78%.

New frontiers in English literacy education: Preparing critical junior secondary Eastern Indonesia students
Get PDFThis study examines innovative methods for teaching English literacy to junior secondary students in Eastern Indonesia, focusing on critical literacy. Using an ethnopedagogical approach, it investigates the challenges and strategies for implementing critical literacy, the effects on students’ perspectives and cultural identities, and develops tailored teaching models. Data were gathered through classroom observations, interviews with two English teachers and 50 eighth-grade students from two schools, and documents analysis. The findings highlight significant resource disparities between urban and rural areas, requiring creative adaptations of critical literacy methods. Incorporating local contexts into literacy activities strengthened students’ cultural identities and enhanced their engagement with global issues. Successful pedagogical models included bilingual multimodal texts, digital literacy integration, and collaborative project-based learning. The study also identified challenges from traditional teaching methods and an exam-focused culture, suggesting a gradual introduction of critical thinking activities. The findings of the study provide valuable insights for teachers and policymakers on implementing effective English literacy education in diverse, resource-limited settings, underscoring the need for culturally response approaches. Keywords: Critical literacy, English as a foreign language, Eastern Indonesia, ethnopedagogy, student identit
The Impact of Research-Based Projects (RBP) in Plant Physiology Course on Undergraduate Student Meta-skills
Get PDFMastery of meta-skills is essential for undergraduate students to prepare themselves for the rapidly changing world driven by advancements in science and technology. Therefore, this study aims to investigate the impact of implementing the research-based project (RBP) model in a plant physiology course on undergraduate students' meta-skills. This study employed a quasi-experimental design with a non-equivalent pre-test and post-test control group design. The research sample consisted of biology education students at the University of Bengkulu selected through purposive sampling. Data were collected using a questionnaire consisting of 79 items, and the research data were analyzed using a One-Way ANCOVA test. The results showed a significant difference in meta-skills between the control and experimental groups, controlling for students' initial meta-skills [F(1,61) = 313.996, p 0.001, np2 = 0.84]. Based on these findings, it can be concluded that the implementation of the research-based project (RBP) model has a substantial or highly effective impact on enhancing undergraduate students' meta-skills.

Efektivitas Latihan Dry Land dan Mobility Terhadap Kecepatan Renang 50M Gaya Bebas Usia 17-18 Tahun
Get PDFPenelitian ini bertujuan untuk membandingkan efektivitas latihan dry land dan latihan mobility dalam meningkatkan kecepatan waktu tempuh atlet. Metode yang digunakan adalah eksperimen dengan dua kelompok perlakuan. Hasil analisis menunjukkan bahwa kelompok dry land mengalami penurunan waktu tempuh sebesar 1,66 detik (5,44%), sedangkan kelompok mobility hanya sebesar 0,65 detik (2,18%). Latihan dry land yang melibatkan kekuatan, pliometrik, dan kecepatan terbukti mampu meningkatkan daya ledak otot, efisiensi neuromuskular, serta koordinasi gerak tubuh. Sementara itu, latihan mobility cenderung berfokus pada peningkatan fleksibilitas dan pencegahan cedera, namun kurang efektif dalam peningkatan kecepatan. Standar deviasi posttest yang lebih kecil pada kelompok dry land juga menunjukkan peningkatan konsistensi performa antar atlet. Temuan ini menegaskan bahwa latihan dry land lebih unggul dalam meningkatkan performa kecepatan dan direkomendasikan sebagai program utama dalam pembinaan atletik, sedangkan latihan mobility berperan sebagai pelengkap

However, the education and religious of the community of Perlanaan Huta IV Village did not show an insignificant influence on sharia banking product in the Kota Perdagangan.Paper Type: Research Article
The Influence of Perceived Value and Quality on Tourist Loyalty in Sharia Tourism with Satisfaction Mediation
Get PDF This study aims to analyze the influence of perceived value and perceived quality on tourist loyalty, with tourist satisfaction as a mediating variable, at the Torang Sari Bulan sharia tourism destination in Lima Puluh Kota Regency. The phenomenon of declining tourist visits in recent years has created a need to evaluate tourists' perceptions of the value and quality of the destination, as well as their satisfaction. This study employs a quantitative approach using a survey method on 385 respondents who are tourists at Torang Sari Bulan. Data analysis was conducted using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS) via the SmartPLS software. The results indicate that perceived value and perceived quality significantly influence tourist satisfaction, and tourist satisfaction positively influences tourist loyalty. Additionally, tourist satisfaction was found to be a significant mediator between perceived value and perceived quality on tourist loyalty. These findings reinforce the theoretical model stating that perceptions of value and quality will drive tourist loyalty when accompanied by high levels of satisfaction. Therefore, managers of Islamic tourism destinations are advised to continue improving perceptions of value and service quality, as well as paying attention to tourist satisfaction in every aspect of service delivery
PENGARUH POSISI PRONASI TERHADAP PENURUNAN KADAR BILIRUBIN PADA BAYI NEONATUS
Get PDFBackground: Hyperbilirubinemia in neonates is a yellowing of the skin, conjunctiva, and sclera of the baby caused by an increase in bilirubin levels in the plasma during the early life of the baby, which appears after a few days following birth. Efforts to manage the increase in bilirubin levels in infants include performing phototherapy and positioning the baby in a prone position every 2 hours, which can help reduce bilirubin levels in the baby. Purpose: Understanding the application of phototherapy and the prone position on the reduction of bilirubin levels in neonates. Method: The method used is through research in the form of a case study conducted in the Level 1 NICU (Perinatology) / Salman Al-Farizi on newborns (Neonates) who meet the inclusion and exclusion criteria, totaling two individuals, with data collection techniques consisting of interviews and observations. The pronation positioning intervention was carried out once a day for three days with a duration of 30 minutes every two hours. Results: To determine the effect of the prone position on the decrease in bilirubin levels after the administration of the action with patient 1 bilirubin levels to 10 mg / dL and patient 2 bilirubin levels to 11 mg / dL. Conclution: The prone position has been proven effective in reducing bilirubin levels in neonates, hospitals are expected to be able to implement the prone position to help reduce high bilirubin levels. Suggestion: For parents at home who have babies experiencing an increase in bilirubin levels or changes in skin color to yellowish, they can expose the baby to sunlight under direct sunlight from 07:00 to 08:00 AM WIB using available tools and materials as long as the light is able to reach the entire area of the baby's body
