Abstract: Education is a crucial foundation for development, yet system reforms are frequently impeded by the gap between policy theory and practical reality. This study presents a systematic review of national educational curriculum execution pathology, focusing on the transition from the School-Based Curriculum (KTSP) to the Emancipated Curriculum (Kurikulum Merdeka) in Indonesia. The primary issue explored is the structural, regulatory, and cultural gap between central government policy design and grassroots school ecosystem readiness. Utilizing a Systematic Literature Review (SLR) based on PRISMA 2020 guidelines, analysis was conducted on indexed international literature published between 2019 and 2026. Results reveal that curriculum implementation failures are frequently rooted in "policy pathology," where radical pedagogical shifts are not proportionally balanced with capacity building and infrastructure. Findings specifically indicate dual-policy fatigue, pedagogical distortion burdening educators with complex administrative tasks (like designing Teaching Modules and diagnostic assessments), weak instructional leadership, and resource disparities between urban and rural schools. Ultimately, this paper proposes adapting the Integrated Curriculum Implementation Model (IDCI) centered on four main subsystems: long-term regulatory stability, curriculum content alignment, organic peer collaboration, and supportive school ecosystems to bridge the curriculum implementation gap.   Keywords: Policy Pathology, School Readiness, Emancipated Curriculum, Curriculum Implementation.   Abstrak: Pendidikan merupakan fondasi krusial bagi peradaban, namun reformasi sistemnya sering terhambat oleh kesenjangan antara teori kebijakan dan realitas di lapangan. Penelitian ini menyajikan tinjauan sistematis mengenai patologi eksekusi kebijakan kurikulum pendidikan nasional, berfokus pada transisi dari Kurikulum Tingkat Satuan Pendidikan (KTSP) hingga Kurikulum Merdeka di Indonesia. Masalah utamanya adalah kesenjangan struktural, regulasi, dan kultural antara desain kebijakan pemerintah pusat dan kesiapan ekosistem sekolah di akar rumput. Menggunakan pendekatan Systematic Literature Review (SLR) berdasarkan pedoman PRISMA 2020, analisis dilakukan terhadap literatur internasional terindeks terbitan 2019-2026. Hasil analisis mengungkap bahwa kegagalan implementasi sering berakar pada "patologi kebijakan", di mana pergeseran paradigma pedagogis radikal tidak diimbangi peningkatan kapasitas sumber daya manusia dan infrastruktur secara proporsional. Temuan menunjukkan adanya kelelahan kebijakan ganda (dual-policy fatigue), distorsi pedagogis yang membebani tenaga pendidik dengan administrasi kompleks (seperti penyusunan Modul Ajar dan asesmen diagnostik), kelemahan kepemimpinan instruksional, serta disparitas sumber daya sekolah urban dan rural. Tulisan ini mengusulkan adaptasi Model Implementasi Kurikulum Terintegrasi (IDCI) yang berpusat pada empat pilar: stabilitas regulasi, keselarasan konten kurikulum, kolaborasi sejawat organik, dan ekosistem sekolah suportif untuk menjembatani kesenjangan implementasi kurikulum.   Kata Kunci: Patologi Kebijakan, Kesiapan Sekolah, Kurikulum Merdeka, Implementasi Kurikulum.

The results indicate that the model successfully classifies data into three categories: low, medium, and high, with an accuracy of 78.89%. Model evaluation shows good performance in the low and high classes, while misclassification occurs in the medium class due to overlapping characteristics between classes. This suggests that the model is effective in identifying data patterns but has limitations when handling data with similar distributions. In conclusion, the Naïve Bayes algorithm is effective in supporting inventory management decision-making, particularly in determining stock priorities based on historical data.

Text based social engineering attacks are a growing cyber threat that is difficult to detect by conventional intrusion detection systems, especially in previously unobserved or zero-day variants. This study proposes a Natural Language Processing Open-Set Intrusion Detection System (NLP-OSIDS) framework that integrates Term Frequency-Inverse Document Frequency (TF-IDF) trigram (1.3-gram) feature representation with an Open-Set Multilayer Perceptron architecture based on energy based scoring to detect zero-day social engineering attacks without requiring training examples from that class. Experiments were conducted on the public dataset phishing_email.csv with 82,486 combined samples from Enron, SpamAssassin, Nazario, Ling, CEAS, and Nigerian Fraud datasets with strict zero-day partitioning following open-set recognition evaluation standards. The results show that NLP-OSIDS achieved an AUROC of 0.7808, surpassing all closed-set baselines (AUROC = 0.500) with the lowest False Positive Rate of 0.0088, while the Zero-Day Detection Rate (ZD-DR) of 0.077 indicates the need for adaptive threshold optimization as a direction for further research.

This study is motivated by the increasing work family conflict experienced by university lecturers due to high academic job demands. One leadership approach that is considered capable of alleviating this conflict is leadership humor. This research aims to examine the effect of positive leadership humor on work family conflict, with coworker socializing as a mediating variable among lecturers at Universitas Lancang Kuning. The study is grounded in the Stimulus Organism Response (SOR) theory and Conservation of Resources (COR) theory, which conceptualize leader humor as a social stimulus and a socioemotional resource. A quantitative approach with a causal research design was employed. Data were collected through structured questionnaires using a Likert scale from 186 lecturers selected through proportional stratified random sampling. Data analysis was conducted using Structural Equation Modeling Partial Least Squares (SEM-PLS). The findings indicate that positive leadership humor has a negative effect on work family conflict and a positive effect on coworker socializing. Furthermore, coworker socializing negatively affects work family conflict and significantly mediates the relationship between leadership humor and work family conflict. The study concludes that positive leadership humor plays a strategic role in fostering a supportive work environment and helping lecturers balance professional and family demands.

Abstract: This study aims to synthesize and characterize barium sulfate (BaSO?) as an ionic compound using a precipitation method, as well as to analyze its physical properties and solubility based on laboratory experimental results. The synthesis was carried out by reacting barium chloride (BaCl?) and sodium sulfate (Na?SO?) solutions in an aqueous medium, resulting in the formation of a white BaSO? precipitate. The precipitate was then separated through filtration, washed with distilled water, and dried to obtain a stable solid product. Characterization was conducted through physical and solubility tests. The results showed that the obtained BaSO? was in the form of a fine white powder. In the solubility test, the compound was found to be insoluble in water, indicating that BaSO? has very low solubility. Based on stoichiometric calculations, the theoretical mass was 2.33 grams, while the experimental mass was 0.55 grams, resulting in a percentage yield of 23.6%. The relatively low yield indicates that the synthesis process was not fully optimal. Theoretically, the formation of BaSO? precipitate is influenced by its very low solubility product constant (Ksp), causing Ba²? and SO?²? ions in solution to form a solid phase. The results of this study are consistent with theoretical principles in terms of precipitate formation, physical properties, and solubility, although differences were observed in the quantitative results. Keywords: Baso?, Precipitation, Ionic Compound, Solubility, Yield Abstrak: Penelitian ini bertujuan untuk mensintesis dan mengkarakterisasi senyawa ion Barium Sulfat (BaSO?) melalui metode pengendapan serta menganalisis sifat fisik dan kelarutannya berdasarkan hasil eksperimen laboratorium. Sintesis dilakukan dengan mereaksikan larutan Barium Klorida (BaCl?) dan natrium sulfat (Na?SO?) dalam medium berair sehingga terbentuk endapan putih BaSO?. Endapan yang dihasilkan kemudian dipisahkan melalui proses filtrasi, dicuci menggunakan Aquades, dan dikeringkan untuk memperoleh padatan yang stabil. Karakterisasi dilakukan melalui uji fisik dan uji kelarutan. Hasil pengamatan menunjukkan bahwa BaSO? yang diperoleh berbentuk serbuk halus berwarna putih. Pada uji kelarutan, senyawa ini tidak larut dalam air, yang menunjukkan bahwa BaSO? memiliki kelarutan yang sangat rendah. Berdasarkan perhitungan stoikiometri, diperoleh massa teoritis sebesar 2,33 gram, sedangkan massa hasil eksperimen sebesar 0,55 gram, sehingga diperoleh persen rendemen sebesar 23,6%. Nilai rendemen yang relatif rendah menunjukkan bahwa proses sintesis belum berlangsung secara optimal. Secara teoritis, pembentukan endapan BaSO? dipengaruhi oleh nilai hasil kali kelarutan (Ksp) yang sangat kecil, sehingga ion Ba²? dan SO?²? dalam larutan cenderung membentuk fase padat. Hasil penelitian ini menunjukkan kesesuaian dengan teori dari segi pembentukan endapan, sifat fisik, dan kelarutan, meskipun terdapat perbedaan pada hasil kuantitatif yang diperoleh. Kata kunci: BaSO?, Pengendapan, Senyawa Ion, Kelarutan, Rendemen

Abstract: This study is based on the importance of understanding precipitation reactions, solubility, and the characteristics of ionic compounds through laboratory experiments. The aim of this research is to synthesize silver chloride (AgCl) via a precipitation reaction, observe the physical characteristics of the resulting precipitate, and examine its solubility in water. The method applied was an experimental approach by mixing 0.01 M AgNO? and NaCl solutions, followed by filtration, drying, and weighing to obtain the experimental mass as well as to calculate the theoretical mass and percentage error. The results indicated the formation of a white AgCl precipitate with a mass of 0.26 grams. The precipitate showed a slight purplish discoloration after exposure to light, indicating its photosensitive nature. The solubility test revealed that AgCl is insoluble in water. The percentage error was found to be 27.8%, which may be attributed to incomplete drying, the presence of impurities, and inaccuracies during filtration and weighing processes. Future studies are recommended to ensure complete drying until constant mass is achieved, reduce contamination, and improve precision in each experimental step to obtain more accurate results.   Keywords: Precipitation, Silver Chloride (AgCl), Solubility, Gravimetry, Photosensitive   Abstrak: Penelitian ini dilatarbelakangi oleh pentingnya pemahaman konsep reaksi presipitasi, kelarutan, dan karakteristik senyawa ionik melalui kegiatan eksperimen laboratorium.

Latar belakang penelitian ini berangkat dari kebutuhan akan sistem yang mampu menentukan kelayakan penerima bantuan secara lebih objektif, cepat, dan akurat dibandingkan metode manual yang rawan subjektif. Dari total 2.304 data masyarakat, penelitian ini menetapkan N Sampel (Data Latih) sebanyak 300 data yang dilabeli secara manual oleh peneliti sebagai Ground Truth (kunci jawaban), yang terdiri dari 78 label "Layak" dan 222 label "Tidak Layak". Data ini kemudian melalui tahap pre-processing (Feature Encoding) untuk mengubah atribut kategorikal menjadi numerik, bukan pembobotan skor. Model Random Forest dilatih menggunakan 300 N Sampel ini sebelum digunakan untuk memprediksi sisa 2004 data uji. Hasil klasifikasi model terhadap keseluruhan 2.304 data menunjukkan 395 masyarakat diprediksi "Layak" dan 1.909 masyarakat diprediksi "Tidak Layak". Evaluasi performa model, yang dihitung dari 20% data uji internal (60 data dari 300 N Sampel), menghasilkan Akurasi 88,33%, Presisi 90,91%, Recall 62,50%, dan F1-Score 74,07%. Hasil ini menunjukkan bahwa model memiliki tingkat presisi yang tinggi (efektif menghindari salah sasaran), meskipun dengan trade-off pada recall yang lebih rendah (masih melewatkan beberapa kasus yang layak). Dengan demikian, sistem ini diharapkan dapat membantu pihak Dinas Sosial dalam meningkatkan akurasi, transparansi, dan efisiensi penentuan penerima bantuan di lapangan.
