Published: May 2024

Introduction:

Adequate workforce and infrastructure as per the Indian Public Health Standards (IPHS) is essential for health-care service delivery at subcenters.

Objectives:

The objective is to assess the existing workforce and infrastructure availability at subcenters and identification of gaps between minimum requirement as per IPHS and actual availability of workforce and Infrastructure at subcenters.

Methods:

It was a cross-sectional observational study. Study units were subcenters. Fifty percent of subcenters of the district were selected using simple random sampling method. Check list prepared from IPHS facility survey formats was used for data collection and collected data were analyzed using Statistical Package for Social Sciences.

Results:

The health worker female was available in adequate numbers, whereas the health worker male was available in 3 subcenters only majority of the subcenters were operating from a rented building. A residential facility for staff was not available at any subcenter. Separate public utilities for males and females were available in only 5 subcenters.

Conclusion:

There is a significant gap in availability of workforce and infrastructure at subcenter as compared to IPHS.

Published: May 2024

Background:

The main goals of periodontal treatment are to gain access to the diseased areas, reduce pocket depth, stop the disease’s progression, and then repair the periodontal tissues that have been harmed by the disease process. Our study compared the efficacy of Type-1 collagen-derived (DMBM) Xenograft Coated with a resorbable-guided tissue regeneration (GTR) membrane and enriched bone graft matrix with concentrated growth factors (CGFs) (Sticky Bone) in the treatment of periodontal infrabony defects.

Methodology:

The study included 40 patients with periodontal infrabony defects who were systemically healthy. According to clinical and radiographic measurements, two groups to which the defects were randomly assigned at the time of surgery Group II Type-1 collagen-derived (DMBM) xenograft coated with a resorbable GTR membrane and Group I-enriched bone graft matrix with CGFs (Sticky Bone).

Results:

At the 6month examination, probing pocket depth reduction was moderately significant in the Group I (7.43 ± 1.51 mm to 3.00 ± 1.53 mm) compared with the Group II (7.14 ± 0.69 mm to 3.00 ± 1.53 mm). The mean gains of clinical attachment were 8.29 ± 1.98 mm to 3.86 ± 1.46 mm in the Group I and 7.85 ± 0.69 mm to 4.53 ± 1.113 mm in the Group II. Radiographic defect depth reduction was slightly greater in the Group I compared with the Group II.

Conclusions:

According to the findings of this study, treating infrabony defects with unfavorable architecture using a Sticky Bone with CGF membrane in combination with bone graft has significantly improved all clinical parameters tested when compared to using a GTR membrane.

Authors: Patil Shital , Toshniwal Sham , Khule Shubhangi
Published: May 2024

Introduction:

Robust data are available regarding the role of D-dimer as a marker of coagulation abnormality in infectious, inflammatory, and malignant process. Its role in predicting coagulation abnormality in the currently ongoing coronavirus disease 2019 (COVID-19) pandemic is evolving. In present we have studied its role in predicting severity, coagulation, and vascular abnormalities such as deep-vein thrombosis (DVT) and pulmonary thromboembolism (PTE). We have also studied the role of D-dimer in the prediction of final radiological outcome as post-COVID lung fibrosis in follow-up.

Materials and Methods:

Prospective, observational study included 1000 COVID-19 cases confirmed with reverse transcription polymerase chain reaction. All cases were assessed with high-resolution computed tomography thorax, oxygen saturation, inflammatory marker as D-dimer at entry point and follow-up. Age, gender, comorbidity, use of bilevel positive airway pressure/noninvasive ventilation (BiPAP/NIV), and outcome as with or without lung fibrosis as per computed tomography (CT) severity were key observations. In selected cases, we have performed lower limb venous Doppler and CT pulmonary angiography to rule out DVT or PTE respectively. Statistical analysis is done by using Chi-square test.

Results:

Age (<50 and >50 years) and gender (male vs. female) has significant association with D-dimer level (P < 0.00001) and (P < 0.010) respectively. CT severity score at entry point with D-dimer level has significant correlation (P < 0.00001). D-dimer level has significant association with duration of illness (DOI) before hospitalization (P < 0.00001). Comorbidities have a significant association with D-dimer level (P < 0.00001). D-dimer level has a significant association with oxygen saturation (P < 0.00001). BIPAP/NIV requirement has a significant association with D-dimer level (P < 0.00001). Timing of BIPAP/NIV requirement during hospitalization has a significant association with D-dimer level (P < 0.00001). Follow-up D-dimer titer during hospitalization compared to normal and abnormal to entry point level has a significant association with post-COVID lung fibrosis, DVT and PTE (P < 0.00001).

Conclusions:

D-dimer is an easily available, and universally acceptable inflammatory marker, which has documented a very crucial role in COVID-19 pneumonia in predicting the severity of illness, and assessing response to treatment during hospitalization. D-dimer has an important role during interventions in the intensive care unit, as follow-up titers have a significant role in step-up or step-down interventions in critical care settings. Correlating D-dimer with variables like DOI, oxygenation status, and timing of BIPAP/NIV at the entry point is important to have a satisfactory treatment outcome.

Authors: Efobi Chilota Chibuife , Ajuba Ifeoma Clara , Ajator Chioma , Chilaka Ugochinyere Jane , Nri-Ezedi Chisom Adaobi
Published: May 2024

Background:

Sickle cell disease (SCD)-related complications lead to school absenteeism and poor academic performance. Educators must be well-versed in the prevalent signs and symptoms of this disease, including first aid care and associated psychosocial factors to curb this trend.

Aim:

To determine teacher’s knowledge of SCD and factors that affect this knowledge and care of children with SCD.

Subjects and Methods:

This was a descriptive survey of all Anambra State teachers invited to a health seminar at the State Education Ministry. Following a verbal informed consent, a pre-tested questionnaire was administered with information on socio demographics, school cadre of employment, marital status, and perception and care of SCD school children retrieved. The correct responses were scored on a scale of 100%. Collated data were cleaned and analyzed using Python 3.10.0. P values of less than 0.05 were considered statistically significant.

Results:

The average age of the 182 responders was 44.2 ± 7.14 years. The majority (90.7%) of teachers were women with post-secondary academic degrees (76.4%). Approximately 57.1% of responders were elementary school teachers. Despite the fact that only 23 (12.6%) of the teachers had attended SCD courses in the past, a good number possessed a reasonable knowledge on SCD. Although the male instructors had less knowledge than females, this difference was not statistically significant (P = 0.142). The highest educational level, prior exposure to SCD seminars, and the type of class the teacher teaches (primary or secondary) were found to impact their awareness and care of SCD patients (P = 0.003, 0.025, and 0.04, respectively).

Conclusion:

More seminars and health conversations on SCD should be held for teachers, with special attention to teachers who work in public schools, male teachers, and those with less than a bachelor’s degree.
Neglected Multi-Articulate Chronic Tophaeceous Cyst
Authors: Obalum Dike Chijioke
Published: May 2024

Gout is a metabolic disease characterised by acute or chronic arthritis and deposition of monosodium urate crystals around joint, bones, soft tissue and kidneys.

This is the case of a 51 year old man who re-presented with a nineteen year history of joint pains and five year history of multiple joint swellings. This followed his defaulting from follow up after an earlier presentation 16 years previously with acute gouty arthritis.

Clinical evaluation revealed a middle aged man with multiple swellings over the hands, ankles, feet, elbows and knees. Serum uric acid was very elevated and radiographs revealed large tophi involving multiple joints. Abdomino-pelvic ultrasound scan and renal function tests were normal.

He was subsequently treated with medications and had significant improvement with clear regression of the size of the tophi. This case demonstrates that delayed treatment of gout or neglected gout over time can lead to tophaceous gouty arthritis.
Unilateral Nevoid Hyperkeratosis of Nipple and Areola in a Filipino Woman: A Case Report and Literature Review
Authors: Cortez Cathlyn Marie , Doria-Ruiz Melanie Joy , Torres-Culala Kara Melissa
Published: May 2024

Nevoid hyperkeratosis of the nipple and areola (NHNA) is a rare, asymptomatic skin condition characterized by verrucous, hyperpigmented papules, and plaques. It predominantly affects the nipple and areola, often bilaterally. Less than 50 cases have been reported worldwide, with only 39% showing unilateral breast involvement. In the Philippines, a single medical literature from 2014 describes two cases of adolescent-onset NHNA. We report a rare case of a 40-year-old, Filipino woman with a 1-year history of a mildly pruritic, solitary, well-demarcated, irregularly shaped, black papule that progressed into a plaque on her right areola. There was suspicion of cutaneous malignancy due to some of the clinical features of the lesion and lack of response to initial treatment. With a correlation between clinical presentation and histopathologic findings, the features were consistent with NHNA. This is a benign skin condition that can mimic and must be differentiated from malignant tumors. Various treatment modalities were described in different medical literatures, some resulting in recurrence or treatment failure, but there is no standard management for this condition. Skin biopsy is crucial to rule out malignancy in cases presenting with persistent and progressively solitary pigmented lesions that do not respond to topical medications. The usual treatment options based on literature include various topicals, lasers, and surgical procedures. In our case, clobetasol propionate ointment was used. While most published cases show varied responses to topical corticosteroids, the result in our case was significant.

Authors: Banashefski Bryana , Sidoti Paul A. , Tai Tak Yee Tania
Published: May 2024

Tube occlusion with elevation of the intraocular pressure (IOP) is a well-described complication of glaucoma drainage implant (GDI) surgery. Most commonly, obstruction occurs at the proximal tube tip from iris, vitreous, or blood. Further intervention is often required to remove the obstruction and reestablish aqueous outflow. Herein, we describe a patient in whom obstruction of the distal tube ostium by clotted blood from a spontaneous hemorrhage into the endplate capsule of an Ahmed Glaucoma Valve (AGV) resulted in severe IOP elevation. This is the first report in the literature of distal tube occlusion by blood from a spontaneous hemorrhage into the endplate capsule of a GDI. Prompt recognition of this entity is important for appropriate treatment planning and patient counselling.

Authors: Tolani Musliu Adetola , Ahmed Muhammed , Hamza Babatunde Kolapo , Muhammad Muhammad Salihu , Bello Ahmad , Maitama Hussaini Yusuf
Published: May 2024

Background:

Due to the invasive nature of prostate biopsy, it is associated with various complications. The study aimed to determine the association of local anesthetic method and prostate volume with the occurrence of these prostate biopsy complications.

Materials and Methods:

It was a prospective study carried out in 106 patients with indications for prostate biopsy. They were randomized into two equal groups receiving either intrarectal lidocaine gel or periprostatic nerve block. Prostate volume was determined using transrectal ultrasound, and patients were further divided into three prostate volume classes (20-40 ml, 40-100 ml, and ≥100 ml). Systematic sextant prostate biopsy was done, and the occurrence of complications (pain, bleeding, infection, and urinary retention) was documented. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software.

Results:

The pain scores of patients were similar irrespective of their prostate volume even with the use of different types of anesthesia. There was no significant tendency for the occurrence of bleeding, infection, and voiding complications when periprostatic nerve block or intrarectal lidocaine gel was used for pain relief. Postbiopsy cystourethritis was, however, significantly associated with the volume of the prostate (P = 0.006).

Conclusion:

The choice of local anesthesia does not affect the occurrence of complications following transrectal prostate biopsy. There is, however, a significant potential for the development of postbiopsy cystourethritis in patients with larger prostates.

Authors: Swain Santosh Kumar , Behera Ishwar Chandra , Nahak Bulu
Published: May 2024

Background:

Foreign bodies (FBs) in the ear, nose, and throat are frequently encountered clinical entities among the children. These ear, nose, and throat FBs are often seen by pediatricians, primary care physicians, and otolaryngologists.

Aim of the Study:

The objective of this study is to analyze various types of FBs in the ear, nose, and throat among children and its clinical profile with its treatment in the pediatric age group.

Materials and Methods:

This descriptive retrospective study was carried out at a tertiary care teaching hospital. During 10-year period from April 2010 to May 2020, 452 pediatric patients with FB in the ear, nose, and throat were managed. The clinical profile and management of these children were analyzed. The clinical data were collected from the admission charts and clinic tickets.

Results:

In this study, the majority of the FBs were found in the nasal cavity, which constitutes 30.53%, whereas 28.31% found in the external auditory canal, 11.72% in the pharynx, 13.49% in the esophagus and 15.72% in laryngotracheobronchial (LTB) tract. The age ranges from 0 to 16 years, with a mean age was 7.21 years. The majority of the ear, nose, and throat FBs were found in the age group of 0–5 years. Out of the 452 cases, 243 (53.76%) were removed under general anesthesia. Vegetable seed was the most common FB in the nose. Coin was the most common FB in the esophagus, whereas vegetable seeds were the most common FB found in the bronchus. The open safety pin is a hazardous LTB FB.

Conclusion:

FBs in the ear, nose, and throat of children are common. The accurate diagnosis and treatment of the FBs in the pediatric age is often challenging. These FBs can be associated with significant morbidity and complications if not removed immediately.

Authors: Dattijo Lamaran Makama , Kabuga Nasir , Aminu Muhammad Bafah , Umar Nasir Ibrahim
Published: May 2024

Background:

Obstetric fistula (OF) continues to be a major health problem in developing countries such as Nigeria. It is a communication between the vagina and bladder/rectum following prolonged obstructed labor that leads to urine/and fecal leakage per vaginam. There is a paucity of information on cost of accessing care by women with OF.

Objective:

The study was to evaluate the cost implications of accessing care and treatment among women with OF in the National Obstetric Fistula Centre, Ningi Bauchi, state.

Materials and Methods:

A prevalence-based cost-of-illness approach was employed in this study to estimate the cost of fistula treatment from the patients' perspective. Data on costs of health-care utilization of services rendered to the patients in the facility and indirect costs were estimated. The data were analyzed with the Statistical Package for the Social Sciences (SPSS V21).

Results:

A total of 75 women participated in the study. The total costs incurred by all the 75 patients amounted to Nigerian Naira (NGN) 8211640.00 (USD 26923.41). The average cost of accessing care for fistula per patient was NGN109488.50 (USD 358.98). Direct cost accounted for 5751740.00 (USD 18858.16), whereas the indirect cost was 2785600.00 (USD9133.11). There was a significant difference in cost of care between patients that were teenagers compared to those who were not (P = 0.04) and the type of treatment (P < 0.001).

Conclusions:

The cost of illness of OF is high in the studied area, and the patients are from the low socioeconomic background. Both the direct and indirect costs were high relative to the national minimum wage in Nigeria. The age of the patients and the type of treatment received by the patient accounted for the differences in cost of illness between the patients.

Histomorphological Effects of Tadalafil on the Liver of Adult Wistar Rat
Authors: Onyilo P. O. , Samuel B. O.
Published: May 2024

Tadalafil is used to treat erectile dysfunction and improve exercise capacity in people with pulmonary arterial hypertension. It promotes blood circulation to the penis during sexual stimulation, thus facilitating the occurrence of an erection. This study examined tadalafil effects on the liver, focusing on potential hepatotoxicity and liver function adverse effects. It aims to contribute to knowledge on tadalafil misuse and abuse, promoting informed decision-making and raising awareness. The study was conducted using fifteen (15) adult Wistar rats randomly assigned into three groups consisting of 5 rats each. Group A was the control group while group B (10 mg/kg of tadalafil) and C (20 mg/kg of tadalafil) were the low dose and high dose groups respectively. Oral administration of tadalafil in treated rats showed evidence of vascular congestion and dilation in the liver tissue, at 20 mg/kg there was periportal hepatitis. Assay of liver function parameters showed increase in liver enzymes across treatment groups compared to control. The presence of periportal hepatitis indicates potential inflammation in the region surrounding the portal area of the liver which suggests that tadalafil may have an impact on hepatocyte morphology and may also influence the inflammatory response in the periportal region of the liver. Hence, Tadalafil should be taken with caution.

Artificial Intelligent for Real-Time Prediction of Rheological Drilling Mud Properties
Authors: Al-Obaidi Ali , Majdi Hasan , Jweeg Muhsin , Hadi Farqad , Jasim Dheyaa , Ellafi Abdulaziz
Published: May 2024

Rheological characterisitcs are very important for drilling fluid functions since it is directly influenced the cutting transportability, hole cleaning ability, lubricity, and filtration loss behaviour while drilling. The Plastic Viscosity (PV), Yield Point (YP), Apparent Viscosity (µa), and gel strength are mud's rheological attributes that can contribute to achieve the drilling fluid functions, but they are only measured once or twice a day, leading to insufficient performance of the drilling fluid functions. In contrast, mud density, marsh funnel, and solid percent are frequently and continuously measurable. There are few attempts to link between the most frequent mud measurements to the less frequent mud measurements which also have a high error rate in their predictions. The Artificial Neural Networks (ANN) and multiple regression analysis (MRA) were conducted using real field measurements to develop new models to determine the rheological mud properties. The ANN was optimized using training and validation datasets of 70% and 30%, respectively. The coefficient of determination (R2) and the root mean square error (RMSE) are found for each model. Upon creating a plot of the predicted PV versus the actual PV, the obtained R2 and RMSE of the ANN model are 0.955 and 0.694 for training datasets, and 0.954 and 0.634 for validation datasets, respectively. In contrast, the results of the MRA are R2 of 0.91 and RMSE of 0.914. The results of other models for determining YP, µa, and gel strength are also successfully checked. These results showed that ANN is able to predict the rheological mud properties with high accuracy, which outperformed the obtained results of MRA. The presented models will help to track in real-time the rheological mud properties that allows better control for the drilling operation problems.
3D Seismic Data Interpretation and Static Reservoir Modeling of Mamuniyat Formation, I and R Oil Fields, Murzuq Basin, Libya
Authors: Abukliesh Mosab , Mostafa Taher , El Din Zein , Abdelhafeez Tharwat
Published: May 2024

The Mamuniyat Formation, located within the Murzuq Basin in western Libya, represents a hydrocarbon reservoir characterized by significant preservation quality. A 3D reservoir modeling method was used in this study to evaluate the Mamuniyat reservoir in the I and R oil fields in the Murzuq Basin. The study looked at the reservoir's structural configuration, facies distribution, and petrophysical parameters. The basic problem in those fields is the large number of dry holes. A 3D seismic survey along with geophysical well logs are the data provided to accomplish the present work. The structural model was constructed based on depth-structure maps derived from seismic data analysis, which revealed the presence of two influential faults affecting the targeted strata within the investigated area. Notably, the primary NNW-SSE-oriented normal fault assumes a critical role as a structural trap. By incorporating well logs and petrophysical parameter computations, facies and property models were established. Facies analysis identified two principal facies, namely sandstone and shale. Based on the analysis of well logs and core data, it has been determined that the Mamuniyat Formation mostly consists of sandstone, with a very small amount of shale ranging from 5 to 10%. The effective porosity values range from moderate (13%) to good (16%), whereas the oil saturation varies between 62% and 91%. Employing the three-dimensional static reservoir modeling technique facilitated the visualization of lithofacies distribution, effective porosity, and hydrocarbon saturation across the reservoir's lateral extent. Consequently, the analysis determined that the upper section of the Mamuniyat Formation predominantly comprises sandstone with a relatively limited proportion of shale. Moreover, this interval exhibits favorable petrophysical characteristics, including high porosity values and significant hydrocarbon saturation.
Remediation of Contaminated Soil with Radium-226 and 228 by Various Methods
Authors: Ibrahim Zaidoon , Al-Mashhadani Asia
Published: May 2024

The most important radionuclides are 226Ra and 228Ra in oil and gas extraction industries due to their radiotoxicity and relatively long half-lives that affect the workers, the public surroundings, and the environment. These extraction activities accumulate naturally occurring radioactive material (NORM) due to the existence of the natural radionuclides in crude oil causing environmental contamination with these radionuclides (226Ra and 228Ra) and their progenies. This research aims to remediate the contaminated soil with these radionuclides by two methods namely mechanical separation and chemical treatment. The first technique is a physical separation of particle size of soil to screen the contaminated soil and evaluate the feasibility of particle size separation. The obtained fractions ranged from less than 37 µm (400 mesh) to higher than 900 µm (20 mesh) diameter of particle size as seven fractions. The results show that 226Ra and 228Ra activity concentrations vary from fraction to fraction. The greatest weight percent in the -900 to +600μm fraction, was 42.3% and the highest levels of activity concentration of 226Ra and 228Ra are concentrated in fine particle size cut (≤37.5μm). The second technique is the batch chemical washing of contaminated soil using the sequential chemical leaching method to extract radium isotopes from the contaminated soil, which is conducted in four successive steps. Five parameters were studied to obtain the best removal efficiency (R%) of 226Ra and 228Ra at optimum conditions for the leaching process; type of solvent, molarity concentration of the solvents, temperature of medium, contact time, and the number of treatment stages. Where, HNO3, HCl, H2SO4, C2H4O2, Na2EDTA, and C₆H₈O₇ were used in the chemical washing. In sequential extraction, the most effective solvents were found to be 1M acetic acid (C2H4O2) with 5:1 ml/g a liquid-to-solid ratio at a temperature of 40˚C, and 2-hour contact time. In the second stage of treatment, it is found that washing the contaminated soil with 0.1M Ethylenediaminetetraacetic disodium (EDTA Na2) after washing with 1M acetic acid (C2H4O2) to be the most effective solvent at the optimum mention conditions, where 94.3% and 93.4% of 226Ra and 228Ra, were removed to the aqueous phase respectively.

In this paper, we introduce and study a new family of sequences called the generalized Leonardo spinors by deﬁning a linear correspondence between the generalized Leonardo quaternions and spinors. We start with deﬁning the generalized Leonardo quaternions and then present their some important properties such as Binet type formula, Catalan’s identity, d’Ocagne’s identity, series sums, etc. We give some interrelations of these quaternions with the Fibonacci and Lucas quaternions. Then, we present the generating functions, sum formulae, various well-known identities, etc. for the Leonardo spinors and show their connection with the Fibonacci and Lucas spinors.

Let G = (V, E), V = {v1, v2, . . . , vn}, be a simple graph of order n and size m, with vertex–degree sequence ∆ = d1 ≥ d2 ≥ · · · ≥ dn = δ > 0. and let s1 ≥ s2 ≥ · · · ≥ sn, si = di − δ + 1 and c1 ≤ c2 ≤ · · · ≤ cn, ci = ∆ − di + 1, be two vertex–degree like sequences. By analogy with the inverse degree graph invariant, ID(G) = ∑n i=1 1 di , the delta inverse degree and reverse inverse degree indices are defined, respectively, as δID(G) = ∑n i=1 1 si and RID(G) = ∑n i=1 1 ci . In this paper we determine sharp bounds on δID(G) and RID(G) and the extremal graphs are characterized.

Open learning analytics (OLA) is a new research field focusing to create an open platform for integration of heterogeneous learning environments. The central notion in OLA is openness, and it relates to architectures, processes, access, and datasets. Learning analytics (LA) usually employs artificial intelligence (AI) technologies and machine learning (ML) algorithms to provide information and predictions, thus enhancing learning experience. AI-based systems provide many benefits, but their implementation raises ethical concerns due to wide range of possible negative consequences. OLA approach amplifies ethical concerns related to AI-based systems, such as privacy, transparency, bias, fairness, etc. In this paper we discuss a comprehensive list of ethical issues in OLA along with mitigations procedures.

Published: May 2024

Landscape has long been recognized as an invaluable resource for tourism development and the foundation for the sustainable development of an entire territory. However, in-depth research on landscape diversity for tourism development from the perspective of landscape science has not received much attention. Applying landscape analysis, field survey, and remote sensing methods, the study has shown diversity in the landscape formation components that determine the diversity of tourism types and products in the Central Highlands. Each landscape unit contains tourism resources, the vertical structure of the landscape unit represents the specificity and tourism potential, and the horizontal structure of the landscape represents the connection of tourism resources along the route. , landscape changes over time demonstrate seasonality in tourism. The landscape structure component is both an object resource for enjoyment and at the same time a place where the tourism process takes place. This is a solid basis for developing many types of tourism such as eco-tourism, cultural tourism, resort tourism, and adventure tourism... and creates the foundation for organizing tourist territories. sustainable history, exploiting and honoring indigenous cultural and historical values, protecting the environment, and ensuring the region's long-term development.

During the implementation of the sixth grade science learning process at SDN 01 Karyomukti, it showed that the majority of students had low learning outcomes. This is due to lack of motivation among students, lack of enthusiasm, lack of enthusiasm and tend to be inactive. Low response to feedback from students to questions and teacher explanations and poor concentration of thinking. To solve problems in order to improve student learning outcomes and student collaboration is to apply the STAD-PjBL collaborative learning model assisted by diorama media which can involve the active role of students. This research employed an experimental methodology designed to examine the effects of specific treatments under controlled conditions. The research utilized a non-equivalent control group design. Both the control and experimental groups underwent a pretest. Different treatments were applied to each group, followed by a posttest to evaluate outcomes. The subjects comprised 16 sixth-grade students from SDN 01 Karyomukti (experimental group) and 13 sixth-grade students from SDN 02 Karyomukti (control group). The pretest and posttest results revealed a significant improvement in the experimental group, with an average increase of 75% using the STAD-PjBL collaborative model assisted by diorama media. Consequently, it can be concluded that the STAD-PjBL collaborative model assisted by diorama media is effective in enhancing the learning outcomes for eclipse topics in the sixth grade at SDN 01 Karyomukti.
