Formulation and Organoleptic Test on Cookies Made from Potato Peel Flour
Processing potatoes into flour is one way to reduce the risk of damage and extend the shelf life of potatoes. Potato flour has high absorption, fine texture, sweet taste, and a distinctive fragrant aroma. Cookies are dry baked goods produced by baking dough made from wheat flour, either with or without substitutes, along with oil or fat, and optionally incorporating other food ingredients and approved additives. Based on this, it is necessary to conduct research on potato flour formulations in cookies with organoleptic tests to determine the best formulation for making cookies from potato peel flour, obtaining the best formulation it can reduce the dependence of the community and industry on the use of wheat flour. The research used a Completely Randomized Design (CRD) with four formulations (0%, 25%, 50%, and 75% potato peel flour substitution) and two repetitions. Organoleptic testing, including hedonic and hedonic quality assessments, was conducted to evaluate panellists' preferences for colour, texture, taste, and aroma. The results showed that cookies with 25% potato peel flour substitution (F1) were the most preferred, achieving the highest scores in all sensory attributes. However, increasing the substitution level resulted in a darker colour, firmer texture, and a more pronounced bitter taste, affecting overall acceptability
Tensile and Flexural Strength Fiberglass Mixed Green Mussel Shell Powder for Fishing Vessel Size below 5 GT
Green mussel (Perna viridis) is a marine organism that is widely cultivated and considered a leading commodity in the fisheries sector. The increase in mussel production has resulted in a significant amount of shell waste. Improperly managed mussel shell waste can have a negative impact on the environment. However, green mussel shell waste has great potential for reuse, one of which is as a composite material in fiberglass manufacturing. The high calcium content in mussel shells can serve as an additional reinforcement in fiberglass composites. The wood crisis as a raw material for boat construction, which also contributes to environmental deforestation, has led to the consideration of alternative materials such as fiberglass for boat building. This research is an experimental study on the utilization of green mussel shell (GMS) waste as a fiberglass mixture material for boat construction. An ideal composition between the GMS waste powder and fiberglass material is expected to enhance the mechanical strength of fiberglass fishing boats. The study shows that the addition of 20% GMS powder in fiberglass lamination improves mechanical properties, with a maximum tensile stress value of 113.23 MPa. Meanwhile, the maximum flexural strength is observed at 15% GMS powder composition, reaching 192.38 MPa. The addition of GMS powder has the potential to strengthen fiberglass, making it suitable for applications such as fishing boat hulls. However, adding more than 30% GMS powder decreases the material’s strength, particularly in tensile testing. Further research is needed to explore the use of GMS powder for waste reduction and to provide insights into its applications in fiberglass boat manufacturing
Evaluating Urban Flood Risk and Mitigation Strategies Using Hydrological and Hydraulic Modelling: A Case Study
This study aims to analyze the characteristics of the Tallo River runoff before and after infrastructure development; identify the main factors causing flood inundation in the affected area and develop flood mitigation strategies based on hydrological and hydraulic modeling. The methods used include data collection using 15 years of rainfall data (2010–2024), topographic maps (DEM), and land use information; hydrological analysis by calculating the design flood discharge using the Rational and Nakayasu methods; hydraulic modeling with HEC-RAS 2D flood inundation simulation to understand the pattern of inundation distribution due to increasing runoff discharge; evaluation of the impact of development by comparing the runoff discharge before and after development and identifying its contribution to flood risk and mitigation strategies by compiling technical recommendations such as raising the embankment, improving drainage, and increasing the elevation of the affected area. The results of the study indicate that flooding in the Tallo River is mainly caused by the river's inability to accommodate the runoff discharge and the backwater effect of the urban drainage system. The increase in discharge due to the construction of a shopping center was recorded as very small (0.84 m³/second) and was not significant to the occurrence of flooding. The proposed mitigation strategies include building a 2.5-meter high embankment, increasing drainage capacity, and regulating the elevation of the affected area. This study is expected to be a reference in flood risk management based on hydrology and hydraulics in urban areas
An Analysis of the Effectiveness of X-Ray as a Supporting Tool in the Autopsy Process: a Literature Review
This study aims to analyze the effectiveness of using X-ray technology as a supporting tool in the forensic autopsy process. The method used is qualitative with a literature study approach that includes various scientific sources such as journals, books, and medical documents. The results showed that X-ray plays an important role in modern autopsy, especially as a non-invasive method to detect foreign bodies, fractures, and internal trauma that are not visible to the naked eye. In addition, technological developments such as postmortem CT (PMCT) and virtual autopsy (virtopsy) utilizing X-ray have also further expanded the application of imaging in the autopsy process, providing a three-dimensional view of the body without the need to perform surgery. Literature studies show that X-ray is effective in detecting internal lesions and foreign bodies, and aids in victim identification. However, this technique has limitations in visualizing soft tissue and microscopic abnormalities, so it should be used as a complement to traditional autopsy. In conclusion, the use of X-ray in autopsy improves diagnostic efficiency and accuracy, but should be combined with other imaging techniques for more comprehensive results
Determinants of Adolescent Female Behavior for Consumption of Fe Tablets on the Working Area of the Nan Balimo Public Health Center
Anemia remains a significant public health issue among female adolescents, particularly due to iron deficiency. The consumption of iron (Fe) tablets is a primary government-recommended intervention, yet adherence levels remain low. This study aimed to analyze the factors influencing Fe tablet consumption behavior among female adolescents in the working area of Nan Balimo Public Health Center, Solok City. A mixed methods approach with an explanatory sequential design was employed. A total of 293 female adolescents were selected using proportional random sampling and analyzed using chi-square tests and multiple logistic regression. Qualitative data were obtained through in-depth interviews with 11 informants. Multivariate analysis revealed four variables significantly associated with Fe tablet consumption behavior: knowledge, attitude, role of health workers, and media exposure (p ≤ 0.05), with the role of health workers emerging as the dominant factor (p = 0.002; POR = 2.655; 95% CI: 1.429–4.935). The qualitative findings supported these results, highlighting challenges such as irregular tablet distribution, monotonous education, weak monitoring, and suboptimal coordination, all contributing to a stagnation in consumption rates, which declined from 96.6 % to 83.06 % over three consecutive quarters. Enhancing the role of health workers is a strategic key to improving Fe tablet adherence among female adolescents. Therefore, it is essential for health centers and health authorities to strengthen communication skills, counseling, and health worker support capacity, while also ensuring the availability of engaging educational media and intensive monitoring

Investigation of Islamic Social Reporting, Public Ownership, Size and Firm Value: Testing the Mediation Effect of Financial Performance: JEL Classification: G32, G34, M14, Q56, Z12
This study aims to analyze the influence of Islamic Social Reporting (ISR), public ownership, and firm size on firm value, with financial performance as a mediating variable, focusing on companies listed in the Jakarta Islamic Index (JII) on the Indonesia Stock Exchange (IDX). ISR serves as a crucial indicator for measuring corporate compliance with Sharia principles, encompassing social and environmental aspects. Research combining ISR with public ownership and firm size mediated by financial performance remains relatively rare in Indonesia. The study observes companies included in the JII, utilizing annual financial report data from 2019 to 2023. Path analysis is used to examine the relationships between variables through 10 research hypotheses. The analysis results indicate that ISR and public ownership (KPP) do not influence firm value (Tobin’s Q, TBQ). Meanwhile, firm size (SIZ) negatively affects financial performance (KJK) and TBQ. In the second model test, KJK appears to positively affect TBQ, while ISR shows a negative effect on TBQ. Furthermore, the Sobel test results reveal that KJK can only mediates the effect of SIZ on TBQ. Mediation effects of KJK on TBQ are not observed for ISR and KPP. These findings confirm that ISR directly affects TBQ. The negative impact of ISR needs further investigation, as it is inconsistent with theoretical concepts

Analysis of the Role of Transformational Leadership in Improving Employee Work Motivation and Performance and its Impact on Hospital Business Sustainability: JEL Classification: M12, M54, I11, I18, L25
This study aims to analyze the influence of transformational leadership on work motivation, employee performance, and business sustainability at Pala Raya Hospital (RSIA Pala Raya) in Tegal Regency, and to examine the mediating role of work motivation and employee performance in this relationship. The background of this study is based on the decline in patient visits and hospital revenue, which raises the need for a sustainability strategy based on internal organizational strengthening. The research method used is a quantitative explanatory approach with a total sampling technique of 200 employee respondents, and data analysis was conducted using SEM-PLS through SmartPLS 4.0. The results show that transformational leadership has a significant and positive effect on work motivation and employee performance, and has an impact on the sustainability of the hospital's business. Work motivation has a stronger influence than performance on sustainability. The mediation test shows that work motivation is a significant mediator in the relationship between transformational leadership and business sustainability, while employee performance is not. The study also identified various obstacles in the implementation of transformational leadership, such as lack of training, bureaucratic culture, and a reward system that does not support innovation. These findings emphasize the importance of the role of inspirational and participatory leadership in building motivation and supporting hospital sustainability
