The essential oil of lemongrass (Cymbopogon citratus) is a high-value commodity widely used in the food, pharmaceutical, and cosmetic industries due to its bioactive components such as citral. Optimizing its distillation process is necessary to achieve maximum yield with time and energy efficiency. This study aims to determine the hourly yield distribution of essential oil from Lombong-type lemongrass during steam distillation and to analyze its extraction kinetics to identify the optimal distillation duration. Distillation was conducted for four hours with yield recorded each hour, and the data were analyzed using pseudo-first-order and pseudo-second-order kinetic models. The results showed that the highest yield was obtained in the first hour (0.1882%), followed by a sharp decline, with no additional yield observed in the fourth hour. The pseudo-first-order model showed the best fit to the experimental data with a rate constant of k = 0,8012/hour. Meanwhile the pseudo-second-order model did not fit well. These findings indicate that the extraction process is dominated by external diffusion and the rapid release of surface volatile compounds. Therefore, it is recommended that distillation duration be limited to two hours to optimize energy and time efficiency.

Shrimp shell waste is a potential marine biomass resource rich in bioactive compounds such as astaxanthin and chitin, yet remains underutilized in the livestock sector. This study aimed to evaluate the effect of incorporating shrimp shell meal into duck (Anas sp.) feed rations on the yolk color intensity of duck eggs. The experimental design applied a completely randomized design (CRD) with a single factor and four treatments: D0 (100% rice bran, control), A1 (rice bran + 2% shrimp shell meal), A2 (rice bran + 6%), and A3 (rice bran + 10%), with a 21-day observation period. The primary parameter measured was yolk color intensity, assessed visually using a standardized color scale. The results indicated that the addition of shrimp shell meal significantly enhanced yolk color intensity, with the highest pigmentation observed in the A3 treatment. Astaxanthin, functioning as a natural carotenoid pigment, was biologically absorbed and distributed into the yolk via lipophilic pathways, while chitin supported gut health and nutrient absorption efficiency. This study aligns with the principles of the circular economy by valorizing marine processing waste as a functional feed ingredient. A 10% inclusion rate was found to be visually optimal; however, further studies are required to assess its physiological impacts and economic feasibility in broader production contexts.

The policy of granting Mining Business Licenses (IUP) to universities under Article 51A of the Minerba Bill raises legal, ethical, and sustainability concerns. This study applies a qualitative approach through literature review to examine the provision from the perspectives of Indonesian law and Islamic teachings. The findings reveal that allowing universities to manage mining permits risks diminishing their academic role, compromising scholarly independence, and fostering potential conflicts of interest. From the standpoint of positive law, this policy contradicts the precautionary principle, social justice, and educational objectives enshrined in the 1945 Constitution, the Higher Education Law, and the Environmental Protection Law. In Islamic thought, irresponsible exploitation of natural resources is classified as fasād (corruption), strictly prohibited, as reflected in Hadith No. 479 narrated by Bukhari. The study concludes by rejecting the provision and recommends repositioning universities as guardians of sustainability values rather than participants in extractive industries.

Stunting remains one of the major nutritional problems in Indonesia. According to the 2024 Indonesian Health Survey (SKI), the prevalence of stunting in Papua Province reached 16.8%. A child’s nutritional status is strongly influenced by dietary intake, particularly protein, which plays a crucial role in growth. One potential source of animal protein is Indian mackerel (Rastrelliger kanagurta), a type of fish commonly found in Papua. Indian mackerel is rich in protein and omega-3 fatty acids but is highly perishable, limiting its shelf life. To address this issue, the fish is processed into flour. Additionally, green spinach is used as a source of fiber and minerals, although it is also prone to spoilage. The spinach is processed by extracting its juice, which is then incorporated into noodle products. Dried noodles were chosen as a medium for fortification because they are widely consumed across age groups and often used as a substitute for rice.This study aimed to determine the effect of adding Indian mackerel flour and green spinach extract on the chemical properties and sensory acceptance of dried noodles. The research methods included nutritional content analysis and organoleptic testing. The sensory evaluation was conducted by 25 semi-trained panelists who were nutrition science students

Electronic money laundering has become a critical issue as a form of cybercrime. Advances in technology demonstrate that digital forensic applications, particularly those utilizing smartphones, can be employed to uncover digital traces of money laundering transactions. This study aims to analyze the relevance of existing legal frameworks, the effectiveness of smartphone forensic techniques, and the challenges faced in their implementation in Indonesia. Based on a review of the literature and regulatory analysis, it was found that legal frameworks such as UU No. 8 of 2010 on the Prevention and Eradication of Money Laundering (TPPU) and UU No. 19 of 2016 on Information and Electronic Transactions (ITE) provide an adequate legal foundation. However, gaps in implementation, such as limited human and technological resources, remain significant obstacles. Forensic techniques, including metadata analysis and device extraction, have shown great potential in identifying the flow of illicit funds. Nonetheless, their application is hindered by data confidentiality and the lack of uniform technical standards. Given the increasing complexity of digital crimes, an integrated approach is required, combining regulatory strengthening with technological capacity building, to enhance the effectiveness of smartphone forensics in addressing electronic money laundering.

This study aims to analyze market sentiment towards Gold Financing Products (PKE) in Islamic banking before and after the Trump Effect phenomenon using the text mining method. This technique involves extracting information from unstructured text data to then be visualized and analyzed using the Natural Language Processing (NLP) approach and a RoBERTa-based classification model. Data was collected through web scraping from the X application with the help of API and processed using Google Colab. From a total of 4,074 tweets analyzed, it was found that the majority of public sentiment was neutral (59%), followed by negative (24%) and positive (17%). This reflects the public's tendency to discuss informatively rather than emotionally, although there was a spike in negative sentiment in certain periods indicating sensitivity to global dynamics, especially the impact of the Trump Effect on gold prices. The resulting wordcloud reveals key topics such as gold prices, buying and selling activities, and institutions such as Pegadaian Syariah and BSI. Terms such as "sharia", "riba", and "principles" emphasize the importance of Islamic financial values ​​in public perception. The results of this study indicate that text mining-based sentiment analysis is effective in capturing the dynamics of public opinion in real-time and can be a strategic tool for Islamic financial institutions in responding to market changes.

A Caesarean section, or C-section, is a surgical procedure where a baby is delivered through an incision made in the mother’s abdomen and uterus. To aid the healing of post-Caesarean wounds, mothers need not only antibiotics but also a diet that provides high-quality nutrition and adequate calories. The research question being investigated is: "Do Age, Parity, Education, and Occupation Affect the Healing Process of Post-Caesarean Wound Stitches?"

Participants were divided into two groups: 49 received catfish extract tablets (the experimental group), and 49 received standard wound care (the control group). Sampling was conducted using purposive sampling techniques. Data were analyzed through both univariate and bivariate methods. The results showed a p value of 0.000 for the experimental group and 0.046 for the control group (both p values < 0.05), indicating that catfish extract tablets significantly influence the healing process of post-Caesarean wound stitches..

Red roses (Rosa damascena Mill.) are known to contain active compounds such as flavonoids, tannins, and vitamin C, which have potential antioxidant and anti-inflammatory properties. However, the utilization of rose flower waste after extraction remains limited. This study aims to formulate and evaluate gel preparations based on red rose extract and post-extraction rose flower waste as an innovation in natural-based topical formulations. This research is an experimental laboratory study using a post-test only design. Three concentration variations were formulated for both the extract (F1, F2, F3) and rose flower waste (F4, F5, F6) using HPMC as the gel base. Physical evaluations included organoleptic testing, homogeneity, pH, adhesion, spreadability, and viscosity. Data were analyzed descriptively and statistically using the Kruskal–Wallis test to determine the effect of concentration variation on physical parameters. All formulations showed good organoleptic and homogeneity results. The pH values were within the safe range for skin (4.75–5.92). Adhesion times met the criteria of >1 second, with a tendency to increase alongside higher concentrations of active ingredients. Spreadability fell within the acceptable range (3–5 cm), decreasing as viscosity increased. The viscosity values ranged from 20,150 to 20,182 cps. There was a significant effect of concentration variation on pH (p < 0.05), adhesion in extract-based gels (p = 0.021), and spreadability in waste-based gels (p = 0.024). In conclusion, gel preparations made from red rose extract and its waste can be successfully formulated with good physical stability and meet standard criteria for topical formulations. Rose flower waste has potential as an alternative active ingredient in the development of natural-based gel products.
