Rehabilitation of Former Nickel Mine Soil through Humate and Compost Application for Revegetation Plant Growth Media
No full textFormer nickel mine lands often have low soil quality and do not support the growth of revegetation plants. This study aims to evaluate the effect of humic substances and compost on improving the quality of post-nickel mine soil and plant growth media. The experiment was conducted using a completely randomized design in a factorial pattern with three levels of humic and compost treatments, as well as a combination of both, applied to nickel post-mining soil. The results showed that the addition of compost significantly increased the cation exchange capacity (CEC) and availability of nutrients (Ca, Mg, K, Na) in the soil. The addition of humic materials had relatively no significant impact on increasing CEC, but could increase phosphorus levels in the soil. In addition, compost and the combination of compost with humic materials can reduce available heavy metal Cr, although it causes an increase in Ni heavy metal levels in the soil. The results of this study make a significant contribution to the rehabilitation of ex-mining land in a sustainable manner, especially the use of humic materials and compost as a strategy to improve soil quality and increase agricultural productivity. The use of these organic materials is proven to be effective in improving the physical, chemical and biological properties of degraded soils, so it can be a more environmentally friendly approach compared to the use of synthetic chemical

The Effect of the SrVER Model Assisted by Virtual Reality (VR) Media on Biology Learning Outcomes of 10th Grade Students at SMAN 3 Mataram
No full textThe difficulty in understanding abstract biological concepts, combined with the dominance of lecture-based methods, hinders student learning outcomes. Therefore, there is a need for innovative, experience-based methods to improve comprehension. This study aimed to determine the effect of the SrVER learning model assisted by Virtual Reality (VR) media on the biology learning outcomes of 10th-grade students at SMAN 3 Mataram. The research used a quantitative approach with a quasi-experimental method, specifically a pre-test post-test control group design. The population included 13 10th-grade classes, and purposive sampling was employed, resulting in 4 classes as the sample. Data were collected through surveys and tests, with data analysis conducted using ANCOVA supported by IBM SPSS Statistics 25. The result showed a significance value of 0.001 ≤ 0.05, indicating a significant effect of the SrVER learning model assisted by VR media on students' biology learning outcomes. The SrVER learning model assisted by VR media proved to be more effective than traditional methods, as evidenced by improved biology learning outcomes
Analisis Faktor Penghambat Keterampilan Membaca Permulaan pada Siswa Kelas II SDN 4 Kesik Kecamatan Masbagik Kabupaten Lombok Timur Tahun Pembelajaran 2024/2025
No full textPenelitian ini bertujuan untuk mengetahui keterampilan membaca permulaan pada siswa kelas II SDN 4 Kesik, dan mengetahui faktor penghambat membaca permulaan pada siswa meliputi II SDN 4 Kesik, serta mengetahui strategi guru dalam mengatasinya. Jenis penelitian ini menggunakan penelitian kualitatif jenis deskriptif. Teknik pengumpulan data dilakukan melalui observasi, wawancara, dan dokumentasi. Teknik analisis data menggunakan metode analisis interaktif analisis model yakni Miles and Huberman. Hasil penelitian menunjukkan bahwa keterampilan membaca siswa kelas II paling banyak berada di level paragraf/cerita dan paling sedikit di level pemula. Faktor penghambat membaca permulaan siswa di kelas II adalah kurangnnya minat, bakat, motivasi dari dalam diri siswa itu sendiri untuk belajar membaca, hal ini juga didukung dengan faktor lingkungan keluarga dan sekolah, yang pertama, kurangnya dukungan dan motivasi dari orang tua dan keluarga terhadap siswa dengan tidak adanya perhatian khusus yang diberikan kepada siswa dalam mengajarkan siswa membaca permulaan dirumah, yang kedua kurangnnya kreativitas guru dalam mengajarkan siswa membaca. Adapun upaya strategi yang digunakan guru dalam mengatasi hambatan membaca permulaan siswa adalah membagai siswa/ memfokuskan mengajar siswa yang belum bisa membaca, menyediakan buku khusus membaca permulaan, melakukan permainan/games, mengingatkan kepada orang tua untuk sering mengajarkan anak membaca dirumah sesibuk apapun mereka dan melatih siswa dengan rutin setiap hari

The Role of Health Insurance in Facilitating Access to Healthcare Utilization: A Case Study of BPJS Kesehatan Users in Banten Province
No full textAccess to healthcare remains a major challenge, especially in developing countries, due to limited infrastructure, medical personnel, and funding. In 2017, the World Bank and WHO reported that nearly half of the world's population struggled to access healthcare due to high costs, including in Indonesia. This study examines the factors influencing BPJS Kesehatan participation and its impact on healthcare utilization. Using probit models and regression techniques, the analysis highlights key determinants, including residence, age, marital status, healthcare utilization, sanitation, household size, income, agricultural participation, health conditions, and employment status. The study also evaluates the effect of insurance coverage on healthcare visits using Negative Binomial Regression and IV Poisson GMM methods. Results indicate that while insurance increases healthcare utilization, factors such as geographic location and out-of-pocket expenses influence access. Findings suggest the need for targeted policies to improve insurance accessibility, particularly in rural areas, and address economic barriers. Limitations include the cross-sectional nature of the data and potential biases in self-reported information. Future research should explore longitudinal data and additional variables to better understand health insurance dynamics
Portrait of Observing, Inferring, and Predicting Skills of Junior High School Students
No full textThe goal of science learning is achieved when students master key skills: observing, inferring, and predicting. Field studies indicate that teachers face challenges in comprehensively assessing these skills. This study aims to portray the observing, inferring, and predicting skills of junior high school students in Tanjungpinang. A quantitative descriptive method was employed, with a target population of eighth-grade students from state junior high schools in Tanjungpinang. Stratified random sampling based on school accreditation levels resulted in a sample of 208 students. Data collection involved a test on work and simple machines material, which was analyzed using descriptive statistics. The findings reveal that the average interval scores for observing, inferring, and predicting skills were 13.52, 5.49, and 1.93, respectively, placing them in the medium category, indicating potential for further development. These results highlight the need for targeted quality improvement programs and increased resource support to enhance science learning. Implementing diverse strategies and innovations in science teaching materials is essential to improve these skills
Analysis of Instrument Validity and Needs for Ethno-STEM Based Science E-Modules to Strengthen Pancasila Student Profiles
No full textThis study aims to analyze the results of the validation of the needs questionnaire and determine the needs of Ethno-STEM-based learning modules to strengthen the Pancasila student profile. This study uses the Research and Development (R&D) method with the Borg and Gall model which focuses on five stages. The results of the study showed that the validation of the needs questionnaire on content validation were 65.33% and the results of the language validation on the Pancasila student profile questionnaire instrument were 65.66% with a good category. The results of the Vindeks analysis on the content validation indicator were 0.91; 0.92; 0.91 and the Vindeks on the language validation indicator was 0.91; 0.92; 0.92 with a valid category on each indicator. The Vindeks results show that the instrument is valid in measuring the character of the Pancasila student profile. Furthermore, based on the results of the needs analysis, it was found that the understanding of junior high school students in Solo Raya regarding the sub-elements of the Pancasila Student Profile ranged from 34-67%, indicating that efforts were needed to strengthen student character. Further Ethno-STEM modules were needed to strengthen the character of the Pancasila Student Profile in all six dimensions
