This study aims to analyze the characteristics of the soil at PIT North with two highwall and lowwall locations at PT Karya Putra Borneo, Kutai Kartanegara Regency, East Kalimantan Province. The research method was carried out by collecting primary data from the results of field tests using the sondir method with the Cone Penetration Test(CPT) tool and laboratory tests using physical properties, specific gravity, grain size, soil consistency, and consolidation tests, as well as secondary data from the results of literature studies. The parameters analyzed for soil characteristics include the sondir cone resistance (qc) value, grain size fraction distribution, soil plasticity index, and the rate of land subsidence through consolidation. The results showed that at PIT North the highwall area had a qc value of 5.6 Mpa, Fr 0.2%, IP 8.06%, Cc 1, a large rate of land subsidence of 3.3 mm with a settlement period of 4 years. In the lowwall area with a qc value of 10.31 Mpa, Fr 0.16%, IP 6.39%, Cc 0.535, the rate of settlement was 4.4 mm with a settlement period of 3 years. From these results, it is concluded that the soil at the highwall and lowwall locations has different compressibility, seeing the different soil Cc values and the soil plasticity index that affect the compressibility level of the soil and the value of the land settlement rate.

This paper aims to analyze the influence of Human Resource Reform and Transformational Leadership on Civil Servant Professionalism, with Resistance to Change as a mediating variable. The research focuses on civil servants at the Semarang City Personnel, Education and Training Agency (BKPP Semarang City), an institution at the forefront of bureaucratic reform and talent management. A quantitative approach was employed through a survey of 77 civil servants using a saturated sampling technique. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the direct and mediation relationships between the research variables. The results showed that Human Resources Reform of Civil Servants and Transformational Leadership had a positive and significant effect on ASN Professionalism. Transformational Leadership was also proven to reduce Resistance to Change, while Human Resources Reform had an indirect effect through reducing resistance. In addition, Resistance to Change had a significant negative effect on ASN Professionalism and mediated the relationship between Human Resources Reform of Civil Servants and ASN Professionalism. These findings confirm that merit system reform, competency development, and inspirational leadership are key factors in improving ASN professionalism, especially when psychological and structural barriers in the form of resistance to change can be minimized. This study provides theoretical contributions in the development of a model of ASN professionalism as well as practical recommendations for local governments in strengthening the implementation of bureaucratic reform.

The feed was formulated using Pearson’s Square method targeting 35% protein, and the soybean meal was fermented using tempe yeast method. The observed parameters included daily growth rate (%), absolute weight gain (grams), survival rate (%), feed utilization efficiency (FUE), and feed conversion ratio (FCR). The results showed that the treatment with 25% fermented soybean meal dose gave the best results with a daily growth rate of 6.42%, absolute weight gain of 0.22 grams, survival rate of 90.66%, and the highest feed utilization efficiency of 0.66.

This study examines the experience of access to health services and resilience strategies in adolescents with unplanned pregnancies in Makassar, Indonesia. Access to quality reproductive health services is important for adolescents' well-being, but they often face systemic barriers that affect access to health services and outcomes. The study used an Interpretative Phenomenological Analysis (IPA) approach on seventeen adolescent girls aged 15–19 years who had an unplanned pregnancy between June–November 2023. Data were collected through in-depth semi-structured interviews, recorded, verbatim transcribed, and analyzed by a six-stage science process. Two main themes were found: Navigating Closed Doors: Systematic Barriers to Care and Finding Light in Darkness: Resilience and Agency. Participants faced a variety of layered barriers, including a lack of information about health services and rights, geographical and economic constraints, age-based discrimination, parental notification obligations, fear of legal consequences especially related to abortion, family control over decisions, and limitations in adolescent-friendly services. Nonetheless, adolescents show resilience through seeking strategic help, resistance to pressure, spiritual and religious coping, peer support, gradual acceptance of maternal identity, educational sustainability, and positive meaningfulness of difficult experiences. These findings point to the need for a transformation of the health system that not only improves attitudes of health workers, but also addresses structural barriers such as confidentiality, age discrimination, and service availability, while strengthening agency and adolescent coping strategies.

Results demonstrate that advanced thermal materials including high-temperature aluminum alloys, titanium alloys, ceramic composites, and thermal barrier coatings can extend component service life by 40-70%, improve thermal management effectiveness by 25-45%, and enhance operational reliability compared to conventional materials. Key implementation challenges include material cost premiums of 150-300%, manufacturing complexity, limited operating experience, qualification testing requirements, and supply chain constraints. Findings reveal that strategic thermal material selection for critical components represents essential enabling technology for high-speed vessel performance, reliability, and operational availability supporting defense, commercial, and emergency response applications requiring sustained high-speed capabilities. This research contributes to marine materials engineering literature by providing evidence-based frameworks for thermal material selection applicable to diverse high-speed vessel applications.

This study aims to examine the implementation of restorative justice within Bungo Regency's criminal judicial system from the perspective of Islamic law. Although restorative justice has been formally adopted in Indonesia through various regulations, its application at the regional level remains an important issue that requires careful attention. The study employs a juridical-empirical research design with a qualitative approach. Data was gathered through observations, in-depth interviews with law enforcement, religious leaders, victims, and offenders, and document analysis. The analysis integrates perspectives from both positive law and Islamic law, particularly focusing on the principles of qiṣāṣ–diyāt, ṣulḥ, ‘afw, ta‘zīr, and maqāṣid al-sharī‘ah. The findings indicate that restorative justice is used in certain criminal cases during the investigative phase in Bungo Regency. However, its effectiveness is limited by factors such as varying levels of readiness among victims and offenders, insufficient technical regulations, community resistance, and inconsistent understanding among law enforcement. From an Islamic law perspective, restorative justice aligns well with Islamic justice principles, particularly those emphasizing public welfare, forgiveness, and restoration. The study concludes that restorative justice is a contemporary manifestation of principles deeply rooted in Islamic legal tradition and not a contradiction of Islamic law. To improve its application, enhancing law enforcement competence, engaging religious and community leaders, and integrating Islamic legal principles into criminal justice policies are essential.

This article explores the concept and implementation of restorative justice in Indonesia, an approach currently at a crucial crossroads within the criminal justice system. Rather than solely focusing on punishment, restorative justice offers a path towards repairing relationships between victims, offenders, and the community, seeking solutions oriented around conflict resolution. Through comprehensive analysis, this paper identifies the philosophical foundations and regulations supporting the adoption of restorative justice, while dissecting the dynamics of its application across various levels of legal processes in Indonesia. However, this noble endeavor is not without its challenges, ranging from institutional resistance and uneven understanding to harmonization with the conventional criminal law framework. Behind every case lies a human story yearning for more substantive justice. Therefore, this article argues that the success of restorative justice does not merely lie in its legal umbrella, but in our ability to understand and embrace the human dimension in every dispute resolution process. Consequently, this paper recommends adaptive and collaborative strategies to strengthen the role of restorative justice, ensuring it can guide our criminal justice system towards a more just and dignified future for all parties.

Diuretic resistance is a serious complication in heart failure patients associated with increased morbidity and mortality. Tolvaptan, a vasopressin V2 receptor antagonist, offers an alternative therapeutic mechanism through aquaresis. This study aims to evaluate the effectiveness and safety of tolvaptan in heart failure patients with diuretic resistance. A retrospective cohort study was conducted on 58 hospitalized patients with NYHA III-IV heart failure and diuretic resistance (urine output <1000 mL/day despite furosemide use ≥80 mg/day) who received tolvaptan 7.5-15 mg/day for 7 days. Variables measured included weight change, urine output, serum sodium, and kidney function. The results showed a significant increase in daily urine output from 820±230 mL to 2180±520 mL (p<0.001), along with an average weight loss of 3.4±1.1 kg (p<0.001). Hypernatremia (>145 mEq/L) occurred in 8.6% of patients. In conclusion, tolvaptan is effective in improving diuresis and reducing congestion in heart failure patients with diuretic resistance, although the risk of hypernatremia should be monitored.

Generalized pustular psoriasis (GPP) is a severe inflammatory form of psoriasis characterized by widespread sterile pustular eruptions. Pro-inflammatory mediators released during chronic inflammation may contribute to comorbidities, including type 2 diabetes mellitus (T2DM). A 65-year-old woman presented with pustular eruptions over almost the entire body for seven days, accompanied by burning sensation and pruritus. Some pustules coalesced forming “lakes of pus,” while others appeared as erythematous plaques with coarse white scales. The patient had a history of T2DM. Based on clinical findings, the patient was diagnosed with GPP. She was hospitalized for seven days and followed up weekly until week 10. Inflammatory mediators such as Th-1, TNF-α, IL-6, IL-7, IL-8, IL-17, and IL-23 in psoriasis may inhibit insulin receptor signaling and glucose uptake, leading to insulin resistance and increased blood glucose levels. The duration of treatment until remission in psoriasis patients with T2DM tends to be longer than in non-diabetic patients. In patients with comorbidities, low-dose methotrexate (5–7.5 mg/week) was administered. The coexistence of GPP and T2DM may lead to more severe exacerbations, prolonged treatment duration, and reduced quality of life, posing challenges in management.

Plastic waste has become one of the main environmental problems due to its nature, which is difficult to decompose naturally and can cause environmental pollution. One alternative waste treatment method that can be applied is to use a plastic melter to melt and recycle plastic waste into useful products. However, the design of plastic melters often lacks consideration of structural strength and safety aspects during the operation process. This study aims to design and engineer a plastic melter using the Finite Element Analysis (FEA) simulation approach to analyze structural resistance to thermal and mechanical loads that occur during the operation process. The research method was carried out through 3D design modeling of plastic melter components using Solidworks software, followed by analysis with FEA simulation on the main component, namely the melting tube. The parameters analyzed include the distribution of von Mises stress, the amount of displacement, and the safety factor. The analysis results show that the analyzed components experience von Mises stress distribution and displacement that are still below the material tolerance limits, with safety factor values above the recommended safety limits. Thus, the resulting plastic melter design is declared safe and can proceed to the manufacturing process. Therefore, the plastic melter design is safe, strong, and feasible to be realized as an effective and sustainable plastic waste processing technology solution.

Hypertension, a global health issue, is increasingly prevalent and significantly contributes to morbidity and mortality. It often coexists with obesity, a key risk factor for hypertension and vascular complications. The combination of hypertension and obesity leads to metabolic changes, chronic inflammation, and oxidative stress that damage retinal blood vessels, directly affecting visual acuity. This literature review examines the relationship between hypertension, obesity, and visual acuity, analyzing 20 articles published between 2021 and 2025, sourced from PubMed, Google Scholar, and ScienceDirect. The study found a significant association between hypertension and obesity with decreased visual acuity. Obesity not only serves as a comorbidity but also as a mediator, worsening hypertension's effects through mechanisms like insulin resistance and endothelial dysfunction. Longitudinal studies indicate that visual impairment is progressive, while cross-sectional studies highlight its high prevalence in hypertensive obese populations. The review emphasizes the need for routine eye exams, blood pressure control, and weight management as preventive measures. In conclusion, hypertension and obesity together significantly increase the risk of visual impairment, necessitating a multidisciplinary approach to care and promoting preventive strategies to preserve eye health and enhance patients' quality of life.

This study investigates biomass-derived surface engineering of AISI 1020 steel for electromedical applications using galam wood charcoal and chicken bone waste as carburizing media. Surface modification is required to improve the mechanical performance of low-carbon steel, particularly in applications that demand high wear resistance and long-term durability. A pack carburizing approach was applied using various ratios of biomass-derived media at a treatment temperature of 800 °C for 2 hours. Chemical composition was analyzed using Optical Emission Spectroscopy (OES), surface hardness was evaluated using Micro Vickers hardness testing, and microstructural characteristics were observed using optical microscopy. The results show a significant increase in surface carbon content with increasing fractions of chicken bone powder, indicating its effectiveness as a carbon donor and diffusion promoter. The surface hardness increased from approximately 150 HV in the untreated condition to a maximum of about 860 HV in the treated specimen. Microstructural observations revealed the formation of a distinct carburized layer with increasing thickness and uniformity, consistent with enhanced carbon diffusion and surface strengthening. These findings demonstrate that biomass-derived surface engineering provides an effective and sustainable approach for improving the surface properties of low-carbon steel. The proposed method offers strong potential for environmentally friendly manufacturing of durable and reliable electromedical components.

The enforcement of civil court judgments in Indonesia frequently encounters obstacles due to parties’ bad faith conduct, such as covert asset transfers or groundless resistance to execution. Although the principle of good faith is a foundational tenet in civil law, its application in the enforcement phase remains inconsistent. This study examines the concept and legal status of the good faith principle in Indonesian positive law concerning civil judgment enforcement and analyzes the legal consequences of its violation. A normative juridical method is employed, utilizing library-based research on primary and secondary legal sources. The findings reveal that while good faith is recognized in substantive civil law, it has not been explicitly incorporated into civil procedural law. Consequently, bad faith actions during enforcement rarely incur clear procedural sanctions. Theoretically, this underscores the need to integrate ethical principles into civil procedure doctrine; practically, it calls for regulatory reforms to embed good faith as a binding procedural obligation in judgment enforcement.

The construction and infrastructure sectors are shifting toward lighter, low-emission, and sustainable materials in response to the high carbon footprint and excessive weight of common materials such as concrete and steel. One promising alternative widely developed is natural fiber–based composites. However, studies comparing mechanical properties of variations of natural fibers within a single framework remain limited. This study aims to evaluate and compare composite mechanical properties reinforced by sisal fiber, bamboo fiber, and pineapple leaf fiber to determine the optimal fiber type for sustainable infrastructure applications. The research methodology involved fabrication of composite specimens using a unidirectional fiber configuration with a resin matrix, molded following ASTM D638 Type I dimensional and geometrical requirements. Tensile testing was conducted to evaluate mechanical responses, including ultimate tensile behavior, deformation characteristics, and elastic properties, which were presented in tabular and graphical forms. The results show that incorporation of all natural fiber types significantly enhanced composite mechanical properties, exhibiting an average tensile strength of approximately 26 MPa. Pineapple leaf fiber demonstrated balanced mechanical behavior combining strength and ductility, while sisal fiber showed superior tensile resistance and rigidity. Bamboo fiber provided moderate mechanical improvement. Overall, natural fiber–reinforced composites demonstrate strong potential as environmentally friendly alternative materials for infrastructure applications, with mechanical characteristics adjustable based on reinforcing fiber type.
