Published: February 2025

Penelitian ini bertujuan untuk mendeskripsikan implementasi asesmen pembelajaran PPKn berbasis HOTS di SMAN 3 Bukittinggi dan juga faktor penghambat dalam mengimplementasikan asesmen berbasis HOTS. Penelitian ini merupakan penelitian deskriptif kualitatif. Adapun informan dalam penelitian ini ditetntukan secara purposive sampling. Uji keabsahan data dalam penelitian ini ialah triangulasi sumber. Data yang diperoleh kemudian dianalisis dengan tahap, reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan Implementasi asesmen berbasis High Order Thingking Skills di SMAN 3 Bukittinggi terdapat tiga tahapan, yaitu tahap perencanaan, pelaksanaan dan terakhir evaluasi. Berdasarkan soal ulangan harian (UH) yang didapatkan bahwa guru masih belum maksimal dalam menerapkan asesmen berbasis HOTS, hal ini dapat dilihat dari masih banyaknya soal-soal yang berbasis Lower Order Thingking Skills. Dari 20 soal yang dibuat oleh guru terdapat soal berbasis LOTS sebanyak 18 soal atau sekitar 90% dan soal berbasis HOTS sebanyak 2 soal atau sekitar 10%. Faktor penghambat dalam mengimplementasikan asesmen berbasis HOTS di SMAN 3 Bukittinggi ialah karena keterbatasan kemampuan dan waktu guru dalam menyusun soal berbasis HOTS, serta siswa belum terbiasa dalam menjawab soal-soal berbasis HOTS.
Prevalence of diffuse idiopathic skeletal hyperostosis and association with coronary artery calcifications in Slovenia
Authors: Lesjak Vesna , Hebar Timea , Pirnat Maja 
Published: February 2025

Abstract

Background
The aim of this study was to analyze the epidemiological aspects of diffuse idiopathic skeletal hyperostosis (DISH) patients in Slovenia, to evaluate the relationship between coronary CT angiography (CCTA)-derived epicardial adipose tissue (EAT) density and coronary artery calcifications (CAC) in patients with and without DISH, and study influencing factors of these parameters.

Patients and methods
The research comprised patients referred for CCTA due to a clinical suspicion of coronary artery disease. DISH, CAC score and EAT attenuation were quantified using non-contrast imaging. Diagnosis of DISH was based on Resnick criteria. The CCTA was assessed for the presence of obstructive coronary artery disease (CAD). The association between DISH and the extent of CAC was explored, using correlation analysis and multivariate regression.

Results
The study cohort included 219 participants. The prevalence of DISH was 7.8%. In univariate logistic regression, body mass index (BMI) (odds ratio [OR] 1.133, p = 0,005), age (OR 1.055, p = 0,032) and diabetes (OR 3.840, p = 0,015) were significantly associated with the condition. However, this association did not persist on multinomial multivariate analysis, but gender, age, hypertension and EAT attenuation were found to be significantly associated with the increasing CAC strata.

Conclusions
The prevalence of DISH found is comparable with prior literature. There was no independent relationship between the prevalence of DISH and CAC. Our data point to a more nuanced and perhaps non-causal link between coronary artery disease and DISH.

Abstract

Background
Over the past few decades, many studies have focused on anthracyclines effect on the heart (cardiotoxicity), but only a few have focused on sarcoma. In this study, we harness the capabilities of advanced cardiac magnetic resonance imaging (MRI) for characterizing anthracyclines-induced cardiotoxicity in sarcoma and compare the results to those from breast cancer patients.

Patients and methods
The patients receive an MRI exam at three timepoints: baseline (pre-treatment), posttreatment, and at 6-months follow-up.

Results
The results demonstrated a differential response in sarcoma, characterized by increasing left-ventricular (LV) mass and decreasing right ventricular ejection fraction (RVEF). In all patients, left ventricular ejection fraction (LVEF) remained > 50% at all timepoints. Myocardial strain was always lower than the normal threshold values and showed small changes between different timepoints. Myocardial T2 and extracellular volume (ECV) showed increasing and decreasing patterns, respectively, in sarcoma, which were the opposite patterns of those in breast cancer. While myocardium T1 showed increasing values in breast cancer, T1 in sarcoma increased post-treatment and then decreased at the 6-months follow-up. The results showed inverse correlation between dose and different strain components in sarcoma, which was not the case in breast cancer. Certain myocardial segments showed high correlation coefficients with dose, which may reflect their increased sensitivity to cardiotoxicity.

Conclusions
Cardiac MRI proved to be a valuable technique for determining anthracycline-induced changes in cardiac function and myocardial tissue composition in sarcoma and differentiating it against breast cancer. It also provides a comprehensive assessment of heart health at baseline, which is important for risk stratification.

Abstract

Background
A considerable proportion of metastatic melanoma (mM) patients do not respond to immune checkpoint inhibitors (ICIs). There is a great need to develop noninvasive biomarkers to detect patients, who do not respond to ICIs early during the course of treatment. The aim of this study was to evaluate the role of early [18F]2fluoro-2-deoxy-D-glucose PET/CT (18F-FDG PET/CT) at week four (W4) and other possible prognostic biomarkers of survival in mM patients receiving ICIs.

Patients and methods
. In this prospective noninterventional clinical study, mM patients receiving ICIs regularly underwent 18F-FDG PET/CT: at baseline, at W4 after ICI initiation, at week sixteen and every 16 weeks thereafter. The tumor response to ICIs at W4 was assessed via modified European Organisation for Research and Treatment of Cancer (EORTC) criteria. Patients with progressive metabolic disease (PMD) were classified into the no clinical benefit group (no-CB), and those with other response types were classified into the clinical benefit group (CB). The primary end point was survival analysis on the basis of the W4 18F-FDG PET/CT response. The secondary endpoints were survival analysis on the basis of LDH, the number of metastatic localizations, and immune-related adverse events (irAEs). Kaplan-Meier analysis and univariate Cox regression analysis were used to assess the impact on survival.

Results
Overall, 71 patients were included. The median follow-up was 37.1 months (952% CI = 30.1–38.0). Three (4%) patients had only baseline scans due to rapid disease progression and death prior to W4 18F-FDG-PET/CT. Fifty-one (72%) patients were classified into the CB group, and 17 (24%) were classified into the no-CB group. There was a statistically significant difference in median overall survival (OS) between the CB group (median OS not reached [NR]; 95% CI = 17.8 months – NR) and the no-CB group (median OS 6.2 months; 95% CI = 4.6 months – NR; p = 0.003). Univariate Cox analysis showed HR of 0.4 (95% CI = 0.18 – 0.72; p = 0.004). median OS was also significantly longer in the group with normal serum LDH levels and the group with irAEs and cutaneous irAEs.

Conclusions
Evaluation of mM patients with early 18F-FDG-PET/CT at W4, who were treated with ICIs, could serve as prognostic imaging biomarkers. Other recognized prognostic biomarkers were the serum LDH level and occurrence of cutaneous irAEs.

Abstract

Background
Electrochemotherapy (ECT) is a local nonsurgical effective tumor treatment in the hand of the clinician for the treatment of patients with liver tumors or metastases. The study aimed to test the technical feasibility and safety of intra-arterial (i.a.) bleomycin administration compared to the established intravenous (i.v.) administration in percutaneous electrochemotherapy (pECT). Furthermore, the equivalence hypothesis was tested between the 2 modalities in terms of local short-term response and progression-free survival.

Patients and methods
Forty-four patients have been recruited and treated by pECT for hepatocellular carcinoma, cholangiocarcinoma and liver metastatic lesions from cancers of different origin: 18 were treated with standard i.v., 26 with bleomycin i.a. administration.

Results
The 2 groups were similar for anagraphic and anamnestic data, as well as for most relevant disease specific characteristics. Technical success of the treatment was obtained in 95% and 100% of patients in i.v. and i.a. groups respectively. Short-term local response was similar in the 2 groups with a slightly higher complete remission (CR) rate in the i.a. group. There were 61.9% CR, 23.8% partial remission (PR), 4.8% stable disease (SD) in the i.v. group, and 80.6%, CR 12.9% PR, 3.2% PD (p = 0.3454). One-year progression free survival was 60% (C.I. 33%–88%) in the i.v. group and 67% (C.I. 42%–91%) in the i.a. group (p = 0.5849).

Conclusions
The results of this study confirmed the safety and feasibility of super-selective i.a. bleomycin administration. Analysis of local response and progression free survival confirmed the equivalence hypothesis of the new modality compared to standard i.v. administration in the treatment of primary and secondary liver malignancies by pECT.

Abstract

Background
Postoperative pneumonia (POP) remains a leading cause of mortality following lung surgery. Recent studies have confirmed that the respiratory tract below the vocal cords is not sterile and often harbours potentially pathogenic microorganisms (PPMs), putting patients with lung malignancies at an increased risk for pulmonary infections.

Patients and methods
The study analysed 149 patients who underwent bronchoscopy for lung lesions suspected to be lung cancer. Protected specimen brush (PSB) samples were obtained during bronchoscopy prior to any specific treatment. Bacterial identification and antimicrobial susceptibility testing were conducted on the isolated strains.

Results
Bacterial colonization was detected in 88.6% of patients, with 21.5% carrying PPMs. Notably, patients with type 2 diabetes exhibited a higher rate of PPM colonization compared to others. Antibiotic susceptibility testing showed no significant differences in efficacy between amoxicillin with clavulanic acid and first-generation cephalosporin in both colonized patients and those with PPMs. Importantly, no multidrug-resistant bacteria were identified.

Conclusions
Our findings indicate a slightly lower PPM colonization rate compared to previous studies, possibly due to the unique geographic characteristics of the study population. The absence of significant differences in bacterial susceptibility between the two tested antibiotics highlights the need for further research to refine perioperative infection management strategies.

Published: February 2025

Laboratorium uji benih memerlukan informasi suhu dan kelembapan ruang untuk menjaga kualitas proses pengujian benih. Saat ini, laboran mencatat parameter lingkungan dua kali sehari pada pukul 9.00 dan 14.00 dengan menggunakan alat ukur terkalibrasi. Namun, metode ini tidak mencakup data di luar jam kerja atau pada hari libur, sehingga tidak memenuhi persyaratan pencatatan kontinu yang diwajibkan oleh Komite Akreditasi Nasional (KAN). Penelitian ini bertujuan untuk mengembangkan sistem pemantauan kualitas udara berbasis IoT yang mampu mencatat suhu dan kelembapan secara kontinu tanpa keterbatasan waktu serta memastikan akurasi data dengan mekanisme kalibrasi menggunakan metode inversi regresi linier. Sistem ini menampilkan data langsung pada layar OLED, menyimpan data di media microSD, dan mengunggahnya ke lembar kerja daring untuk pemantauan dan analisis lebih lanjut. Hasil pengujian menunjukkan bahwa sistem memiliki tingkat akurasi pengukuran sebesar 98% untuk suhu dan 97% untuk kelembapan setelah menggunakan inversi regresi linier dengan menggunakan 15 data. Dengan demikian, sistem ini mampu menggantikan metode pencatatan manual yang terbatas dan memenuhi persyaratan pencatatan kontinu dari KAN.

Abstract
Seed testing laboratories require temperature and humidity information to maintain the quality of seed testing processes. Currently, laboratory staff record environmental parameters twice daily at 9:00 AM and 2:00 PM using calibrated measuring instruments. However, this method does not cover data outside working hours or during holidays, thus failing to meet the continuous recording requirements mandated by the National Accreditation Committee (KAN). This study aims to develop an IoT-based air quality monitoring system capable of recording temperature and humidity continuously without time constraints while ensuring data accuracy through a calibration mechanism using the linear regression inversion method. The system displays real-time data on an OLED screen, stores data on a microSD card, and uploads it to an online spreadsheet for further monitoring and analysis. The test results show that the system achieves a measurement accuracy of 98% for temperature and 97% for humidity after applying the linear regression inversion method by using 15 data. Thus, the system can replace the limited manual recording method and meet the continuous recording requirements set by the KAN.

Metodologi penelitian meliputi pengumpulan data, text mining, pra-pemrosesan teks, implementasi teknik Word2vec dan Doc2vec, serta pengukuran Cosine Similarity. Hasil penelitian menunjukkan bahwa teknik Word2vec menghasilkan nilai Cosine Similarity yang lebih tinggi dibandingkan dengan Doc2vec untuk pasangan jurnal yang sama, dapat dilihat pada pasangan jurnal J02 dengan J14 memiliki nilai Cosine Similarity 0.892 pada teknik Word2vec, sedangkan pada Doc2vec nilainya 0.434. Hal ini menandakan bahwa hasil teknik Word2vec terbukti lebih efektif dalam menangkap kemiripan semantik antara jurnal-jurnal dibandingkan dengan teknik Doc2vec.

Abstract
The digital era has made access to many online documents easier and faster, but it has also created complex challenges in information management and analysis. One of the main challenges is measuring the similarity between documents, which is crucial for various applications such as plagiarism detection. In response to this challenge, many techniques can be used to represent documents as vectors to measure document similarity. In this research, Word2vec and Doc2vec techniques are used to represent documents as vectors, and Cosine Similarity is used to measure document similarity. The research objects are abstract paragraphs from 20 scientific journals on data mining published between 2020 and 2024 from Gunadarma University's E-Journal. The research methodology includes data collection, text mining, text pre-processing, Word2vec and Doc2vec techniques implementations, and Cosine Similarity measurement. The results show that the Word2vec technique produces higher Cosine Similarity values compared to Doc2vec for the same journal pairs, as seen in the journal pair J02 and J14 having a Cosine Similarity value of 0.892 using the Word2vec technique, while with Doc2vec the value is 0.434. This indicates that the Word2vec technique proves to be more effective in capturing semantic similarities between journals compared to the Doc2vec technique.

This paper proposes a systematic methodological approach to identifying dominant species complexes in algal metacommunities. The approach was applied during comprehensive studies of plankton, benthos, and periphyton in various lotic and lentic continental ecosystems. The algorithm of the proposed approach consists of the following steps:
-	Selecting the dominant species complex based on both cell count and biomass, as algal communities comprise species that vary significantly in cell volume (ranging from a few cubic micrometers to several tens of thousands of cubic micrometers).
-	Using relative abundance rather than absolute cell count or biomass to determine dominance, due to the high variability in algal abundance caused by abiotic, biotic, climatic, and anthropogenic factors.
-	Differentiating between dominant species (≥10 % of the total cell count or biomass) and subdominant species (5-9.9% of the total cell count or biomass).
-	Analyzing the spatial dynamics of dominant species complexes within a metacommunity framework, considering their distribution and interactions across three-dimensional space - i.e., among phytoplankton, benthic, and periphytic algal communities.
The dominant species complexes in lotic and lentic ecosystems may be classified into:
-	Monodominant complexes, primarily composed of Bacillariophyta.
-	Oligodominant complexes, such as Bacillariophyta-Cyanobacteria and Bacillariophyta-Chlorophyta associations.
-	Polydominant complexes, involving Bacillariophyta - Cyanobacteria -Chlorophyta assemblages.
The presence of planktonic Cyanobacteria in periphytic algal communities is attributed to the mass effect - a process in which species sediment from the water column, where they are abundant, onto an atypical habitat, such as hard substrata. Conversely, species may also transition from the substrata into the water column, further supporting the concept of a unified autotrophic network in aquatic ecosystems.
Thus, analyzing the structure of dominant species complexes - while accounting for dominant and subdominant species in planktonic and periphytic algal metacommunities - is a crucial aspect of hydrobiological research in lotic and lentic continental ecosystems of Ukraine.
An Analysis of Figurative Language in Sabrina Carpenter’s Song Album “Short N’ Sweet”
Authors: Gea Mira Kristiyanti , Pasaribu Tiara Kristina , Sinambela Erika 
Published: February 2025

The study is very important because when listening to songs, most people only focus on the music rather than the lyrics without knowing the meaning of the song. This study aims to find out the types of figurative language in “Short n Sweet” song album by Sabrina Carpenter and how is the figurative language realized in the song album. This research used mix-method research namely quantitative and qualitative. This study used Perrine (1992) theory which classified figurative language into 12 types. However, this research only focuses into 6 types of figurative language with the research results of 97 data. There are Metaphor (16), Simile (14), Personification (9), Symbol (19), Hyperbole (23), and Irony (16). The realization is that there are six types of figurative language, namely metaphors (comparing two different ideas, namely intelligence with sharpest tools and describing a partner with bee). Simile (make a direct comparison using the term "like"). Personification (inanimate objects namely fan and car are given human characteristics or talents). Symbol (use elements of numbers and drink brands with meanings that are different from their literal meanings). Hyperbole (use clearly exaggerated statements to emphasize certain feelings and situations). Irony (there is a mismatch between what is said or expected and the truth or deepest feelings behind the statement). This study is very important for english department and literature students, teacher, lecturer, and other researchers because it will teach them how to evaluate and analyze figurative language both in songs and in other media.
