Abstract

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. Tujuan penelitian ini adalah untuk mensintesis senyawa perak klorida (AgCl) melalui reaksi presipitasi, mengkarakterisasi sifat fisik yang terbentuk, serta menganalisis sifat kelarutannya dalam air. Metode yang digunakan adalah metode eksperimen dengan mencampurkan larutan AgNO? dan NaCl masing-masing 0,01 M, dilanjutkan dengan proses filtrasi, pengeringan, dan penimbangan untuk menentukan massa hasil serta menghitung massa teoritis dan persen kesalahan. Hasil penelitian menunjukkan terbentuknya endapan putih AgCl dengan massa sebesar 0,26 gram yang kemudian mengalami perubahan warna menjadi keunguan akibat pengaruh cahaya (sifat fotosensitif). Uji kelarutan menunjukkan bahwa AgCl tidak larut dalam air. Persen kesalahan yang diperoleh sebesar 27,8% yang disebabkan oleh faktor pengeringan yang belum optimal, adanya pengotor, serta kesalahan dalam proses penyaringan dan penimbangan. Disarankan bagi peneliti selanjutnya untuk meningkatkan ketelitian dalam proses pengeringan hingga mencapai massa konstan, meminimalkan kontaminasi, serta menggunakan teknik pemurnian yang lebih baik agar diperoleh hasil yang lebih akurat.   Kata kunci: Presipitasi, Perak Klorida (AgCl), Kelarutan, Gravimetri, Fotosensitif

Abstract

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 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 analyze the evidentiary system in medical malpractice cases involving specialist doctors under Law Number 8 of 1981 concerning Criminal Procedure Law and Law Number 20 of 2025 and to compare the effectiveness of both systems in providing legal protection for patients. This research is normative legal research employing statutory and comparative approaches, using primary, secondary, and tertiary legal materials analyzed qualitatively. The results show that the evidentiary system under Law Number 8 of 1981 remains limited and formalistic, thus not fully accommodating the complexity of proof in medical malpractice cases which require scientific and professional approaches. Meanwhile, Law Number 20 of 2025 expands the scope of admissible evidence, including electronic and scientific evidence, making it more adaptive to developments in science and technology in the medical field. The comparison indicates a paradigm shift from formal legal certainty toward a balance between legal certainty, justice, and utility. Therefore, the evidentiary regulation under Law Number 20 of 2025 is considered more responsive in handling medical malpractice cases by specialist doctors and provides more optimal legal protection for patients as victims.

Abstract

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.

Abstract

The advancement of information technology has encouraged companies to manage data more effectively in decision-making processes, including inventory management. Problems such as overstock, deadstock, and stockout frequently occur due to the lack of data-driven management based on historical transactions. This study aims to analyze and classify inventory demand levels using the Naïve Bayes algorithm to optimize inventory management at PT Soala Gogo Natama. This research employs a quantitative descriptive method with a case study approach. The dataset consists of 300 observations divided into training data (210) and testing data (90) with 9 variables. The analysis process includes data preprocessing, implementation of the Gaussian Naïve Bayes algorithm using Python, and model evaluation using accuracy, confusion matrix, and classification report. 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.
