This review article evaluates the physical characteristics and stability of Oil in Water (O/W) and Water in Oil (W/O) creams through a comparative literature study published between 2021 and 2026. The evaluation focuses on important parameters, including viscosity, spreadability, adhesion, pH, and accelerated stability testing. The findings reveal that O/W creams generally have lower viscosity and greater spreadability, making them more suitable for daily cosmetic and therapeutic applications due to their lighter texture and better aesthetic acceptance. In contrast, W/O creams demonstrate higher physical stability, stronger adhesion, and superior occlusive properties, which are beneficial for protecting sensitive active ingredients and maintaining skin hydration over longer periods. The differences in performance are strongly influenced by the optimization of emulsifier Hydrophilic-Lipophilic Balance (HLB) values and the ratio between oil and water phases. Both cream types show good biocompatibility with skin pH ranging from 4.5 to 6.5, indicating their safety and effectiveness for topical pharmaceutical and cosmetic formulations.

Inguinal hernia is a common abdominal hernia occurring in the groin region and generally requires surgical management, with postoperative pain control being an important aspect of patient recovery. This case reports a 55-year-old male presenting with a left groin mass for 6 months, which was initially reducible but subsequently became difficult to reduce, accompanied by severe pain and activity limitation. Physical examination revealed a left inguinal mass measuring approximately 3.03 × 2.17 cm, with firm consistency, well-defined borders, immobility, and tenderness, while ultrasonography demonstrated dilation of the left inguinal canal after provocation; based on these findings, a diagnosis of left inguinal hernia with ASA physical status II was established. The patient was managed with herniorrhaphy under regional anesthesia using a subarachnoid block, followed by ultrasound-guided ilioinguinal and iliohypogastric nerve blocks with levobupivacaine and pehacain for postoperative analgesia. Intraoperatively, the patient remained hemodynamically stable, and postoperatively, pain intensity decreased gradually from a VAS score of 6 to 2 within 24 hours and reached 0 on the second postoperative day without significant complaints. This case demonstrates that regional anesthesia combined with ultrasound-guided peripheral nerve block may support postoperative pain control after herniorrhaphy, maintain clinical stability, and improve patient comfort during recovery.

Background: The management of hemorrhagic shock in obstetrics typically involves aggressive fluid resuscitation, often leading to iatrogenic fluid overload and pulmonary edema. Implementing a timely fluid de-escalation (deresuscitation) strategy is critical to facilitate ventilator weaning and achieve early extubation. Case Illustration: A 31-year-old female (G5P3A1) was admitted to the ICU following emergency Re-Cesarean Section due to Grade IV hemorrhagic shock caused by postpartum hemorrhage (PPH) and placenta previa totalis. Intraoperative aggressive resuscitation triggered iatrogenic fluid overload, manifesting as bilateral pulmonary edema and severe gas exchange impairment (initial AaDO2 of 459 mmHg and lactate level of 2.8 mmol/L). Management and Results: Following initial hemodynamic stabilization, an active fluid de-escalation strategy was initiated on Post-Operative Day 1 (POD 1) using continuous furosemide infusion at 10 mg/hour targeting a negative fluid balance. The patient achieved a negative fluid balance of -1485 mL within 24 hours, accompanied by a significant increase in urine output (7.8 mL/kg/hour). This approach successfully reduced the AaDO2 to 162 mmHg and improved lactate clearance to 1.8 mmol/L without compromising hemodynamic stability. The patient was successfully extubated within 18 hours of ICU admission. Conclusion: Early transition from resuscitation to fluid de-escalation, guided by perfusion targets (lactate) and oxygenation markers (AaDO2), is safe in critical obstetric cases. This strategy effectively resolves pulmonary edema and accelerates early extubation.

The increase in national divorce rates based on data from the Central Statistics Agency in 2024, which reached 394,608 cases and rose to 438,168 cases in 2025, indicates that family conflicts remain a legal and social issue affecting family resilience, child protection, and social stability in society. In the Indonesian legal system, divorce is fundamentally placed as a last resort (ultimum remedium) after reconciliation thru mediation, as regulated in Law Number 1 of 1974 on Marriage, as amended by Law Number 16 of 2019, Supreme Court Regulation Number 1 of 2016 on Mediation Procedures in Court, and provisions in Law Number 18 of 2003 on Advocates. However, studies on the optimization of the preventive role of advocates in divorce mediation are still relatively limited, even tho advocates hold a strategic position as independent law enforcers within the judicial system. This research aims to analyze the legal position of lawyers in divorce mediation and to formulate the optimization of the lawyer's role in preventing avoidable divorces. The research uses a normative juridical method with legislative, conceptual, case, and comparative approaches thru the analysis of various related regulations, legal doctrines, and scientific literature. The research results show that lawyers not only function as legal representatives in litigation processes but also have a preventive role as legal advisors, negotiators, and facilitators of peaceful family dispute resolution. The optimization of these roles can be achieved thru the provision of objective legal advice, early identification of the root causes of family conflicts, facilitation of communication between parties, and collaboration with mediators and family counselors in the mediation process.

Debt restructuring and Suspension of Debt Payment Obligations (PKPU) are legal instruments in the Indonesian bankruptcy system aimed at providing legal protection and maintaining a balance of interests between debtors and creditors. In practice, the PKPU process is not only related to the settlement of debts but also involves business continuity, legal certainty, and the stability of the business world. This research aims to analyze the position and optimization of the role of advocates in debt restructuring and the PKPU process in Indonesia, as well as to examine their role in providing legal protection for both debtors and creditors. The research uses a normative juridical method with a legislative and conceptual approach thru the analysis of Law Number 37 of 2004 concerning Bankruptcy and PKPU, Law Number 18 of 2003 concerning Advocates, the Civil Code, as well as various regulations related to the resolution of commercial disputes. The research results show that lawyers hold a strategic position not only as legal representatives in Commercial Courts but also as legal advisors, negotiators, and debt restructuring facilitators who play a role in maintaining the balance of legal protection for the parties involved. The optimization of the role of lawyers is necessary thru the strengthening of professionalism, integrity, business competence, and a business rescue approach so that the PKPU and bankruptcy processes are not misused as tools of business pressure, but rather become means of fair, effective, and legally certain commercial dispute resolution.

Background: Class II restoration according to the classification of Greene Vardiman Black is one of the procedures in dental conservation that often presents a challenge for operators or dentists during treatment. Class II restorations have their own level of difficulty, particularly during the placement of restorative materials into the cavity. One of the possible failures in Class II restorative treatment is marginal leakage, which can lead to microleakage at the restoration margins. Purpose: To report the success of class II restoration with composite resin using tofflmire matrix. Case report: A 23-year-old female patient came with a complaint of cavities, the complaint was felt since 1 year ago in the lower left back tooth, there was no pain and had never been treated. In the case, preparation and restoration were carried out using composite resin with isolation using tofflmire matrix, applied using an Incremental technique. Discussion: Class II posterior tooth restorations have challenges such as leakage due to the techniques and materials used. Composite resin is chosen because of its good adaptation, esthetics, and wear resistance. Incremental techniques are preferred because they reduce polymerization stress and provide optimal curing results. Tofflemire matrix is ​​used for stability and soft tissue protection.Conclusion: The selection of composite resin with an Incremental technique and the use of a Tofflemire matrix provides more optimal, aesthetic, and minimal risk of failure results for class II posterior tooth restorations.

This study aims to qualitatively analyze the impact of order cancellations and customer ratings on the performance, performance, and income of online motorcycle taxi (Gojek) drivers in the Slawi region. The research method used a qualitative approach with data collection techniques through in-depth interviews, observation, and documentation of a number of active drivers. The results show that the high rate of order cancellations, both from customers and the system, negatively impacts driver income stability and reduces work time efficiency. Furthermore, customer ratings play a crucial role in determining driver access to orders, incentives, and account sustainability. Drivers with low ratings tend to experience decreased performance due to limited opportunities to receive orders. On the other hand, the pressure to maintain high ratings also affects drivers' psychological state and work strategies. This study concludes that order cancellations and customer ratings are crucial factors that are interrelated in influencing the work quality and welfare of online motorcycle taxi drivers. Therefore, fairer and more transparent platform policies are needed to maintain a balance between customer satisfaction and driver protection.

Low-rank coal generally has a high moisture content, which results in a low calorific value and suboptimal quality for utilization as an energy source. One method that can be applied to improve coal quality is the Upgrading Brown Coal (UBC) process, which functions to reduce moisture content and increase fixed carbon value. This study aims to analyze the effect of heating time and the ratio of used oil composition on improving coal quality based on proximate parameters. The research method includes collecting coal samples from four locations in Samarinda and its surrounding areas, namely SMAN 1 Samarinda, Bhineka Street, Palaran Stadium, and Tani Bakti Village. The samples were analyzed using proximate analysis, including inherent moisture (IM), ash content (AC), volatile matter (VM), and fixed carbon (FC), both before and after the UBC process. The upgrading process was carried out with variations in heating time and used oil composition as a coating medium to enhance coal stability and prevent moisture reabsorption. The final results of the upgrading process showed the best values of inherent moisture at 13.64%, ash content at 4.66%, volatile matter at 55.06%, and fixed carbon at 44.94%. The results indicate that the UBC process is capable of reducing inherent moisture and increasing fixed carbon, thereby improving coal quality. Variations in heating time and used oil composition have a significant effect on changes in proximate parameters. Longer heating time and an appropriate ratio of used oil composition result in a more optimal improvement in coal quality.

The furniture industry is a strategic sector in the regional economy, including in Sikka Regency, East Nusa Tenggara, where the JeparaWaidoko furniture business owned by Mr. Agus Komarudin has been operating since 2010. In running its business, Mebel JeparaWaidoko faces various operational risks that have the potential to disrupt production continuity, employee safety, and financial stability. This study aims to comprehensively analyze the risk management process at this business, including risk identification, risk analysis and assessment, evaluation and prioritization, and implementation and monitoring of risk controls. The method used was descriptive qualitative, using in-depth interviews with the business owner and field observations. The study identified three main risks: the risk of flooding, the risk of workplace accidents due to the use of production machinery, and the risk of rising raw material prices. All three are categorized as high-priority risks requiring planned and systematic management. These findings indicate that risk management practices at Mebel JeparaWaidoko remain informal and intuitive, despite the implementation of simple control measures. This study recommends formalizing an ISO 31000-based risk management system, improving occupational health and safety programs, and diversifying raw material suppliers as medium-term strategic steps

This systematic literature study conducts a comparative analysis of Reliability-Centered Maintenance (RCM) and Total Productive Maintenance (TPM) in manufacturing, and proposes an integrated hybrid model. The research concludes that RCM and TPM are fundamentally distinct methodologies: RCM excels in risk-based, analytical management of complex, high-criticality assets, while TPM is superior for achieving broad-based productivity gains and cultural empowerment through total employee involvement. The effectiveness of each approach is contingent upon factors such as asset characteristics, organizational culture, data availability, and level of automation. To leverage their complementary strengths, the study proposes the Synergistic RCM-TPM Hybrid Model (SRTHM). This framework advocates for a sequential implementation where TPM establishes the foundational operational stability, discipline, and data culture, upon which selective RCM analysis is applied to critical assets for precision risk management. The model incorporates explicit feedback mechanisms to create a continuous organizational learning cycle. The study provides a contingency framework for methodology selection and a practical roadmap for integration, offering theoretical and practical guidance for building more resilient and context-appropriate maintenance systems in modern manufacturing.

Edentulism is a condition of total tooth loss that has a significant impact on the efficiency of mastics, phonetics, and facial aesthetics. This case report presents the rehabilitation of a 72-year-old female patient with a condition of total mandible edentulus using two standard-diameter implants that support the overdenture with a locator retention system. Treatment procedures include clinical evaluation, radiographic analysis, implant placement, prosthesis placement, as well as follow-up evaluation to assess function and comfort. The results of the treatment showed an increase in patient retention, stability, and comfort in daily activities. In addition, patients reported improved confidence and quality of life after the use of implant-based overdentures. These findings confirm that overdenture with mandibular implant support is a predictive, effective, and reliable rehabilitation method in treating total edentulism. The success of this case provides clinical evidence that implant-based approaches are able to overcome the limitations of conventional prostheses, as well as being a solution that supports the functional and psychosocial aspects of elderly patients. Thus, implant-based overdenture can be recommended as the primary therapeutic option in the rehabilitation of mandibular edentulism.

Risk management is a crucial aspect of business sustainability, especially for Micro, Small, and Medium Enterprises (MSMEs) in the culinary sector which face various business environment uncertainties. This study aims to analyze the implementation of operational risk management at Warung Ecco Roso Kediri, covering the processes of risk identification, analysis, evaluation, control, and monitoring applied by the business owner. This research employed a qualitative descriptive method with a case study approach, using in-depth interviews and field observation for data collection. The results showed that the implementation of operational risk management at Warung Ecco Roso Kediri has been carried out across all process stages, yet it remains simple, informal, and based on the owner’s experience without systematic documentation. The main identified risks include raw material risks, market demand risks, business competition risks, as well as service and hygiene risks. The control strategies implemented focus on maintaining product quality, operational efficiency, and price adjustment. Although the applied system is not formally structured, these risk management practices are considered effective in maintaining business stability and continuity. This study recommends the development of Standard Operating Procedures (SOPs), risk documentation, and the use of a risk matrix to improve risk management effectiveness in the future.

Exchange rates are a crucial indicator in an open economy, playing a significant role in influencing international trade, investment flows, and overall macroeconomic stability. This study aims to analyze the impact of rupiah exchange rate fluctuations on Indonesia’s economic growth during the period 2014–2023. The research employs a descriptive qualitative approach using secondary data obtained from official publications of Statistics Indonesia and Bank Indonesia. The main variables analyzed include the rupiah exchange rate against the United States dollar and Indonesia’s economic growth. The findings indicate that exchange rate movements are closely related to economic growth dynamics, particularly through international trade mechanisms, production costs, and the stability of the real sector. Depreciation of the exchange rate tends to enhance export competitiveness, but it may also trigger inflation due to rising import prices. Conversely, appreciation can help control inflation but may weaken export competitiveness. Therefore, maintaining exchange rate stability is essential to support sustainable economic growth and strengthen national economic resilience.

Ballast water plays a crucial role in maintaining ship stability during shipping, but it also carries environmental and human health risks due to the heavy metals it carries. This study aims to examine the health risks posed by exposure to heavy metals in ballast water and to assess the effectiveness of management practices implemented in the maritime industry. Using a literature review method, this study examines various scientific sources related to the content of heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) in ballast water, as well as their impacts on human health and marine ecosystems. The results indicate that heavy metals in ballast water can cause long-term toxic effects such as neurological disorders, kidney damage, and respiratory and reproductive disorders. The greatest risk is experienced by maritime workers who are directly exposed through inhalation or skin contact during the ballast water sampling and processing process. To minimize these risks, strict work safety protocols, improved ballast water treatment technology, and regular monitoring of heavy metal levels are required. Thus, this study emphasizes the importance of strengthening ballast water management policies and practices that are oriented towards human health and environmental sustainability.

Proprioceptive sensor data, including inertial measurement units (IMU), joint encoders, and torque sensors, plays a critical role in state estimation for quadruped robots operating in dynamic and unstructured environments. However, these signals are often degraded by various sources of error, such as high-frequency noise, bias, drift, and contact-induced disturbances, which directly affect estimation accuracy and stability. This study presents a systematic analysis of sensor-specific noise characteristics and evaluates the effectiveness of preprocessing methods tailored to each sensor modality. Specifically, moving average filtering is applied to encoder signals to mitigate noise amplification during differentiation, while first-order low-pass filtering is employed for IMU and torque signals to suppress high-frequency noise. Experimental results on a publicly available quadruped dataset demonstrate that encoder velocity RMSE is reduced by 12.09%, high-frequency energy decreases by 59.63%, and signal-to-noise ratio (SNR) improves by 145.6%. However, variance reductions remain limited (3.39% for IMU and 4.05% for torque), indicating the persistence of impulsive, non-Gaussian noise caused by contact events. These findings highlight that linear preprocessing methods are effective for attenuating high-frequency noise but insufficient for handling non-Gaussian disturbances. The study provides practical insights into the effectiveness and limitations of preprocessing strategies, serving as a foundation for developing more robust signal processing and state estimation frameworks in quadruped robotics.

This study aims to explain the context of the Value Added Tax (VAT) increase policy and its relevance to the trade sector, while also presenting a framework for analyzing the tax burden. The data sources used consist of publications from the last four years, namely from 2021 to 2024. The observed phenomena are then analyzed using various secondary data obtained from scientific journals, official government reports, and other reliable sources relevant to the research topic, in order to provide a comprehensive overview. The conclusions are drawn based on empirical facts, the impacts of the tax increase, and the government’s mitigation efforts to ensure taxpayer compliance. The increase in the VAT rate represents an important step in fiscal reform aimed at increasing state revenue and reducing the budget deficit. This policy has significant potential to support the growth of the national budget, particularly in financing priority sectors such as infrastructure, education, and healthcare. However, the VAT increase may also affect consumers’ purchasing power and trade activities, thus requiring appropriate supporting policies to minimize negative impacts. Therefore, it is expected that this policy will contribute to sustainable economic stability and promote long-term national economic growth.

The implementation of regional autonomy and fiscal decentralization aims to enhance local governments' financial independence. However, fiscal imbalances between the central and regional governments led to the enactment of Law Number 1 of 2022 (UU HKPD), designed to strengthen regional fiscal capacity. This law introduces a piggyback tax system through a surcharge on the Motor Vehicle Tax. This study analyzes the dynamics of the piggyback tax system in Semarang City, focusing on the implications for taxpayer resistance and regional financial capacity. Using a descriptive qualitative approach, the study reviewed secondary data from regulatory documents, financial reports, and academic literature. The findings show that the shift towards centralistic fiscal policies and the increase in tax burdens have sparked significant taxpayer resistance. This resistance occurs both passively, due to poor regulatory literacy, and actively, through delays in tax payments. The resistance damages the psychological contract between the state and citizens, undermining local financial stability. It risks reducing local revenue, increasing tax collection costs, and limiting fiscal space for infrastructure development. The study suggests that Semarang’s government needs to adopt an adaptive governance framework with transparent tax allocation, digitalization of services, and persuasive policies to restore public trust and encourage compliance.

Global economic uncertainty and exchange rate fluctuations pose significant challenges to monetary stability in Indonesia, particularly in maintaining a controlled inflation rate. This study aims to analyze the transmission mechanism of the rupiah exchange rate to the inflation rate in Indonesia from 2015 to 2024. The method used in this study is library research by collecting, reviewing, and synthesizing data from various scientific literature, official central bank reports, and related journal articles published over the past decade. The research findings indicate that rupiah depreciation has a significant influence on rising inflation through the imported inflation channel, where currency depreciation increases the cost of raw materials for industries dependent on foreign markets. Furthermore, the findings reveal that the effectiveness of this transmission is influenced by public expectations and monetary policy taken by Bank Indonesia through adjustments to the benchmark interest rate. The implications of this study emphasize the importance of synergy between a stable exchange rate policy and controlling the supply of domestic goods to minimize the impact of external shocks on public purchasing power. The government and monetary authorities are advised to continue strengthening foreign exchange reserves and encouraging the use of local currencies in international transactions to reduce dependence on the United States dollar and maintain national price stability.

The adoption of holocratic leadership systems has become a crucial strategy for startups navigating market volatility, which demands organizational agility through the elimination of traditional hierarchies. This study aims to analyze the transformation of the Human Resource (HR) department's role within holocratic systems and its impact on HR efficiency in startup environments. Employing an integrative literature review approach, this research synthesizes various findings from reputable global and national journals published within the last five years to map the shifts in managerial functions. The results indicate that in structures devoid of conventional managers, the HR role transforms from a controlling authority into a system architect and governance facilitator that maintains compliance with the organizational constitution. HR efficiency is achieved through clear authority distribution within dynamic roles, transparent peer-to-peer feedback mechanisms, and the removal of slow bureaucratic coordination costs. The contribution of this research lies in the formulation of the "HR-as-a-Platform" conceptual model, which shifts the focus of management practices from personal supervision to systemic infrastructure optimization. The practical implications provide a guide for startup founders to re-engineer HR functions to support individual autonomy without sacrificing operational stability. This study confirms that the success of non-hierarchical organizations relies heavily on the integration of radical autonomy and robust digital protocols facilitated by the newly defined HR function.
