Characterization of Dunggilata Gold Tailings and Treatment Process Recommendations
No full textRare earth elements (REEs) are a group of seventeen metallic elements consisting of scandium (Sc), yttrium (Y), and fifteen other lanthanide elements. Rare earth metals have an important role in various technologies, so the analysis and separation of these elements from their minerals is very important to do. This study aims to characterize the tailings through X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) techniques. The results of XRD analysis show that the mineral composition of tailings is dominated by quartz (SiO₂) with a percentage of 88%, followed by albite (NaAlSi3O8) with a percentage of 11%. In addition, the results of XRF analysis show that the main elemental composition in the tailings consists of SiO₂ (69.294%), Al₂O₃ (20.20%), and Fe₂O₃ (4.681%). In addition, heavy metal concentrations in the tailings indicate a potentially serious risk of environmental pollution, with arsenic (As) reaching 100 ppm and mercury (Hg) more than 5 ppm. In addition, rare earth elements identified in the tailings include cerium (Ce) at 14,578 ppm, lanthanum (La) at 7,850 ppm, and neodymium (Nd) at 6,897 ppm. This method is expected to help tailings management, reduce environmental impacts, and support sustainable mineral utilization
The Effectiveness of the Two Stay Two Stray (TSTS) Cooperative Learning Model Compared to the Jigsaw Type on Students' Science Learning Outcomes
No full textThe mismatch of models and objectives causes students' learning outcomes to vary. This study aims to determine the effectiveness of the Two Stay Two Stray (TSTS) cooperative learning model compared to the Jigsaw type in improving the learning outcomes of science students on the human digestive system material for class V SDIT Mutiara Hati Rembang. This study uses an experimental research type with a quasi-experimental research design in the form of Non-Equivalent Control Group Design. The sample in this study amounted to 54 students. The sampling technique used purposive sampling. Class VB as the control class and class VA as the experimental class. The data collection technique used a test technique in the form of pretest and posttest questions; non-test techniques in the form of interviews, observations, and documentation. The data analysis technique consists of initial data analysis in the form of normality tests and homogeneity tests and final data analysis in the form of t-tests and N-Gain tests. Based on the t-test, the sig. value is 0.013 (<0.05) meaning that Ho is rejected and Ha is accepted. So, there is a significant difference in the effectiveness of the application of the TSTS and Jigsaw learning models on the learning outcomes of science students for class V SDIT Mutiara Hati Rembang. Furthermore, based on the results of the N-Gain test, the control class was 0.46 and the experimental class was 0.56. In conclusion, the TSTS learning model is more effective than Jigsaw on social science learning outcomesThe mismatch of models and objectives causes students' learning outcomes to vary.

Service Improvement Strategy of National Veterinary Public Health Laboratory, Ministry of Agriculture Indonesia Towards A Clean and Serving Bureaucracy Area
No full textThe contamination of animal-based foods poses risks to consumer health and economic stability, including trade losses and reduced consumer confidence. As the national reference laboratory under the Ministry of Agriculture, Indonesia, the Quality Testing and Certification Agency for Animal Products (BPMSPH) ensures product quality and certification. However, increasing sample volume and limited resources create service challenges, requiring urgent improvements to meet clean and responsive public service standards. This study aims to develop strategies for enhancing BPMSPH services toward Clean and Serving Bureaucracy Area (WBBM) standards. A mixed-method approach was used, combining primary data from interviews and questionnaires with secondary data from relevant agencies. SERVQUAL and AHP analyses identified service gaps and prioritized improvements. Findings show that BPMSPH services do not fully meet customer expectations, with key gaps in digital service accessibility, officer problem-solving capabilities, and customer assistance availability. AHP analysis prioritizes assurance and responsiveness, emphasizing the need for enhancing officer competency and developing digital services. The implementation of these strategies is expected to enhance BPMSPH’s service efficiency, increase customer satisfaction, and support the achievement of WBBM certification. By strengthening service assurance and responsiveness, BPMSPH can provide more professional, effective, and accessible public services, aligning with stakeholder expectations and regulatory standard

The Implementation of a Problem-Based Learning (PBL) Model Assisted by Wordwall Media in the IPAS Subject to Enhance Students' Learning Outcomes
No full textThe Problem Based Learning (PBL) instructional model is an approach used to address problems encountered in real-world activities. It is a learning model that also considers deep thinking styles and skillful problem formulation to help students gain an understanding of the main topics and key concepts. This study aims to evaluate the implementation of the Problem Based Learning (PBL) model, supported by Wordwall media, in improving the learning outcomes of fourth grade students in the IPAS subject at SD Negeri 1 Bayung Lencir. The research employed a Classroom Action Research (PTK) method over four cycles. The study involved 21 fourth grade students, and data were collected through tests, observations, interviews, and documentation. The results indicated a significant improvement in students’ learning outcomes from the pre-test to the post-test. Before the model was applied, only one student achieved mastery. After implementing the PBL model with Wordwall media, the number of students reaching mastery increased to 11 out of 12. The use of PBL and Wordwall media proved effective in enhancing student motivation and learning outcomes, as well as in supporting active student engagement in the learning process. The study recommends that teachers adopt a problem-based learning model supported by interactive media to further improve student learning outcome
Reduction of Nitrite Levels in Edible Bird Nest on Lombok Island with Alkali Solution and Oxygen Water
No full textIn this study, sampling was carried out at 3 locations of swallow nest farmers, namely in East Lombok, Central Lombok and West Lombok. The type of swallow nest used in this study was the Linchi swallow nest. This study was a quantitative study, namely to find the best variation in soaking time with alkaline water and Oxygen Water to reduce nitrite levels. Sample measurement using a Uv-Vis spectrophotometer instrument and characterization using FTIR. The results of the study showed the highest reduction in nitrite levels using an alkaline solvent with a pH of 7.5, Central Lombok, East Lombok and West Lombok Edible Bird’s Nest Sample, respectively, as follows: 87.88%; 96.26%; and 94.59% with an optimum contact time of 30 minutes. While the highest reduction in nitrite levels for Central Lombok, East Lombok and West Lombok, Edible Bird’s Nest samples were as follows: 92.51%; 98.5%; and 97.85% with an optimum contact time of 15 minutes. This is also supported by FTIR spectra data from optimum conditions for reducing nitrite levels where the characteristics of the FTIR spectra in the 1400 cm-1 wavenumber region have a %T value after treatment> to %T before treatment. The results of the macronutrient test showed that the bird's nest contains carbohydrates, proteins and lipids. While the results of the phytochemical test showed that the bird's nest sample contained phenolic compounds. In this study, it has been successfully reduced nitrite levels in bird's nests using alkaline solvents pH 7.5 and Oxygen Water which is the latest method that is cheaper and more efficient
