This study aimed to evaluate the effect of substituting cassava leaves (Manihot esculenta Crantz) into a complete feed based on odot grass (Pennisetum purpureum cv. Mott) on in vitro rumen fermentation characteristics, including gas production, dry matter degradation (DMD), organic matter degradation (OMD), ammonia (NH₃) concentration, and microbial protein synthesis. A laboratory experiment was conducted using a Completely Randomized Design (CRD) consisting of five dietary treatments (0%, 5%, 10%, 15%, and 20% cassava leaf inclusion) with four replications each. The feed samples were incubated for 48 hours using rumen fluid collected from slaughtered Limousin cattle, selected purposively from the Ruminant Abattoir in Malang City based on consistent diet and health status to minimize variability. Feed ingredients were sun-dried, ground, and mixed into complete feed formulations using standardized proportions. In vitro gas production was measured using a gas-tight syringe technique, while DMD and OMD were calculated by weighing residues after fermentation. NH₃ concentrations were analyzed using the Conway microdiffusion method, and microbial protein synthesis was estimated based on the weight of microbial biomass derived from fermentation residues. All variables were statistically analyzed using ANOVA followed by Duncan’s Multiple Range Test at a 5% significance level. The results showed that a 20% substitution of cassava leaves significantly (P<0.01) improved the gas production rate, DMD, OMD, NH₃ concentration, and microbial protein synthesis, while decreasing gas production potential. These findings demonstrate the potential of cassava leaves as a sustainable protein-rich ingredient in ruminant complete feed formulations.

This study examines the application of Article 362 jo Article 64 paragraph (1) of the Criminal Code (KUHP) in the Kupang District Court Decision Number 170/Pid.B/2023 against the defendant Sherly Oktaviana Nggeon, who was proven to have committed the crime of repeatedly stealing gold at her workplace, Toko Mas Sahabat. This study aims to assess the accuracy of the application of criminal law norms to concrete facts revealed at the trial and analyze the judge's considerations both from juridical and non-juridical aspects in imposing a verdict. The method used is a normative juridical approach with secondary data sources obtained through literature studies of laws and regulations, doctrines, and court decisions. The results of the study show that although the panel of judges has formally applied Article 362 jo Article 64 paragraph (1) of the Criminal Code by qualifying the defendant's actions as a continuing act (voortgezette handeling), this approach is not entirely appropriate substantively. The act of theft was carried out in different periods, against different objects, and accompanied by the forgery of a memorandum of sale of elements that can legally be qualified as a separate criminal offense based on Article 263 of the Criminal Code. However, in the judge's decision, this act of forgery was not explicitly considered either as an additional charge or as a burden of punishment. This raises the issue of justice, considering that the merging of all acts into one criminal act reduces the weight of criminal responsibility that the defendant should receive, and does not fully reflect the overall dimension of the crime committed. From a non-juridical aspect, the judge considered the defendant's background, good faith to return the damages, and the social and economic conditions of the defendant in imposing a two-year prison sentence. However, this consideration is considered disproportionate when compared to the amount of loss, the consistency of the evil act, and the existence of counterfeiting which contributes to aggravating the character of the crime. This study emphasizes the importance of a more comprehensive legal approach in qualifying compound crimes (concursus realis), as well as the need for judges to

The selection of appropriate solvents in sterile injection formulations plays a pivotal role in determining the stability, efficacy, and safety of pharmaceutical products. Among the commonly utilized solvents, Dimethyl Sulfoxide (DMSO), Polyethylene Glycol (PEG), and pyrogen-free water exhibit distinct physicochemical properties and functional roles. This study aims to analyze the characteristics, functions, and implications of these three solvents within the context of sterile injectable preparations. The research methodology involves a comprehensive review of six peer-reviewed scientific articles published within the last five years, focusing on solvent performance, compatibility, and safety profiles. Findings reveal that DMSO is highly effective in dissolving lipophilic compounds due to its strong solvating capacity. However, its use at elevated concentrations may lead to irritation and cytotoxicity, necessitating careful dosage regulation. PEG, particularly in its flexible molecular weight variants, serves as a co-solvent and viscosity modifier, enhancing solubility and stability of active pharmaceutical ingredients. Pyrogen-free water, characterized by its inertness and biocompatibility, remains the gold standard for injection solvents, offering minimal risk and broad applicability across drug classes. The study underscores the importance of aligning solvent selection with the physicochemical nature of the drug, intended route of administration, and patient safety considerations. Furthermore, the potential for combining solvents to achieve optimized formulations is highlighted as a promising avenue for future pharmaceutical development. Such combinations may offer enhanced solubility, reduced toxicity, and improved delivery mechanisms, particularly for complex or poorly soluble compounds. In conclusion, understanding the nuanced roles of DMSO, PEG, and pyrogen-free water is essential for formulating safe and effective sterile injections. This research contributes to the growing body of knowledge supporting rational solvent selection and encourages further exploration into innovative solvent systems for advanced drug delivery.

Pneumonia detection from chest X-ray images is widely used in computer-aided diagnostic systems. However, effective clinical decision support requires not only accurate classification performance but also consideration of unequal error costs, since false negative predictions may lead to more severe consequences than false positives. In addition, prediction probabilities must be well calibrated to support threshold-based medical decisions such as triage and patient escalation. This research investigates asymmetric misclassification costs and probability calibration for binary classification (PNEUMONIA vs. NORMAL) using the Hugging Face dataset hf-vision/chest-xray-pneumonia. The proposed framework utilizes a ResNet-18 architecture integrated with cost-sensitive learning through weighted cross-entropy loss (FN:FP = 5:1), threshold optimization based on validation data to reduce expected cost, and post-hoc temperature scaling for improving probability calibration. Experimental results on the independent test set indicate that the cost-sensitive approach enhances specificity and decreases expected cost compared to the conventional cross-entropy baseline. Furthermore, temperature scaling improves the reliability of probabilistic predictions, as demonstrated by better negative log-likelihood and Brier score values. The study also explores selective prediction strategies to balance prediction coverage and risk reduction, complemented by Grad-CAM visualizations and structured failure-case analysis for qualitative assessment. Overall, the findings demonstrate that incorporating cost-aware decision thresholds and calibrated probability estimates can serve as lightweight yet effective enhancements for chest X-ray classification systems in clinical decision-support applications.

Anemia during pregnancy is a significant health issue that contributes to the incidence of low-birth-weight (LBW) babies. At the Bere-Bere Community Health Center, the prevalence of LBW is 15%, higher than the national average, and the prevalence of anemia in pregnant women is 30%. This study aimed to analyze the relationship between hemoglobin (Hb) levels in pregnant women and the incidence of LBW at the center. A cross-sectional design was used with 30 pregnant women selected via purposive sampling. Hb levels were categorized into anemia (Hb <11 g/dL) and normal (Hb ≥11 g/dL), while birth weight was categorized into LBW (<2500 grams) and normal (≥2500 grams). Data analysis was performed using univariate and bivariate analysis with the Chi-Square test. Results showed that 43.3% of pregnant women experienced anemia and 33.3% of babies had LBW. Of the 13 anemic mothers, 61.5% gave birth to LBW babies, while only 11.8% of mothers with normal Hb levels had LBW babies. The Chi-Square test revealed a significant relationship (p = 0.004, p < 0.05) between maternal Hb levels and LBW incidence. In conclusion, maternal anemia is significantly associated with LBW, highlighting the need for interventions such as iron supplementation, nutrition education, and regular check-ups to prevent anemia and reduce LBW rates.

The problem faced by Kelurahan Kebagusan is that there is no structured system in determining the allocation of aid funds to the community, so the distribution process is often uneven and less targeted. So far, the determination of aid recipients is only based on subjective observations and manual assessments that have the potential to cause ineffectiveness in decision making. Therefore, a decision support system was designed to assist the kelurahan in prioritizing beneficiaries objectively and transparently. This system uses the Simple Additive Weighting (SAW) method, which allows the assessment process to be carried out based on the weights of several predetermined criteria, such as economic conditions, number of dependents, employment status, and home ownership. The result of this system development is a desktop-based application using the Java programming language, which is expected to help the kelurahan in managing data and performing calculations quickly and accurately, so that the allocation of aid funds can be more targeted and fair.   Keywords: Decision Support System, Simple Additive Weighting, Fund Allocation, Kebagusan Village.
