Hyperkeratotic hand dermatitis (HHD) is a chronic hand eczema subtype marked by thick hyperkeratotic plaques, painful fissures, and minimal erythema or vesiculation.It is diagnostically challenging due to overlap with palmoplantar psoriasis and keratoderma and is strongly linked to repeated irritant exposure in wet work. A 60-year-old male taro leaf farmer presented with itching and burning on the palms and backs of both hands, spreading to the forearms for 2–3 weeks. Examination revealed papules, hyperpigmented plaques, erythematous macules, irregular scaling, and about 1 cm palmar fissures on both hands. The working diagnosis was chronic hyperkeratotic hand dermatitis. Initial treatment included oral cetirizine, topical betamethasone valerate, and Vaseline gel, plus education on using long rubber gloves at work. HHD results from skin barrier dysfunction and keratinocyte hyperproliferation caused by repeated irritant exposure. In this case, exposure to taro leaves and prolonged rubber glove use likely maintained irritation and occlusion. Differential diagnoses include palmoplantar psoriasis, contact dermatitis, and tinea manuum. Management involves potent corticosteroids, antihistamines, occlusive emollients, and occupational modifications such as replacing gloves and limiting occlusion time. Identifying occupational factors in HHD is essential. Effective management requires combined topical therapy, symptom control, and strict workplace modifications, along with patient education and allergy screening if needed.

Hospitals are places that provide health services to the community through the services they offer. In their operations, hospitals require fixed assets to be us|ed ind|epe|nd|ently or i|n co|mbi|nati|on wi|th other assets in the hospital for long-term operations. The fixed assets us|ed by hospitals make a significant contribution because they require large expenditures and are used over the long term. This study was conducted with the aim of analyzing the application of fixed asset accounting treatment at XYZ Hospital in accordance with PSAK 216. This study adopted a descriptive qualitative methodological approach to achieve the predetermined research objectives. The data collection technique applied was conducting interviews with the asset management department and obtaining accounting treatment documents and a detailed list of fixed assets of XYZ Hospital. The research findings show that the handling of fixed assets and the implementation of PSAK 216 on fixed assets at XYZ Hospital indicate that XYZ Hospital records its fixed assets if they have a useful life of more than one year, measures the initial cost of assets from the acquisition price, revalues assets but there is no method explaining the calculation method, applies the straight-line method for depreciation, discontinues fixed assets if they can no longer be used, and records all these events in its financial statements. It is important to apply PSAK 216 in implementing accounting treatments to minimize and prevent the risk of fixed asset recording errors in financial statements.

Inheritance involving adopted children often becomes a complex and controversial issue in Indonesia’s dual legal system. In Islamic law, inheritance is strictly based on blood and marital relationships; therefore, adopted children are not considered legal heirs. To address this limitation, Article 209 of the Compilation of Islamic Law (KHI) introduces the concept of a wasiat wajibah or mandatory will, allowing adopted children to receive up to one-third of the adoptive parents’ estate. In contrast, civil law treats adopted children as equivalent to biological children if the adoption is legally recognized, granting them full inheritance rights. These contrasting provisions create legal disparities and confusion within society. This study aims to explore the different legal treatments of adopted children under both systems, identify the challenges they face, and analyze efforts toward harmonization. Using a qualitative, normative-juridical approach through literature and regulatory analysis, the study finds that Islamic law restricts inheritance through gifts and wills, while civil law ensures equal rights. Challenges include legal uncertainty, inconsistent judicial interpretations, and potential conflicts between adopted and biological heirs. Harmonization efforts are reflected in KHI provisions, legal reforms on adoption, and judicial practices seeking to balance sharia principles, social justice, and legal certainty.

Enteric bacterial infectious diseases such as Escherichia coli are still a serious health problem in many countries, mainly due to the increasing cases of antibiotic resistance that cause the effectiveness of conventional therapies to decline. This condition encourages the search for safer and more effective natural alternatives, one of which is propolis produced by the Trigona sp. bee Trigona sp. Propolis is known to contain a variety of bioactive compounds, including flavonoids and phenolic acid, which act as antimicrobials. This study aims to test the antibacterial activity of propolis extract against E. coli by the sumpray diffusion method. The results of the study showed that there was an inhibition zone that varied according to the concentration of the extract. At a concentration of 10%, an average inhibition zone of 19.85 mm (strong category), a 20% concentration of 22.35 mm (very strong), and a concentration of 30% reaches 26.62 mm (very strong). In comparison, the positive control of ciprofloxacin produced 21.25 mm of resistance, while the negative control (DMSO) showed no activity. ANOVA analysis confirmed significant differences between treatments (p < 0.05). These findings confirm that propolis extract has the potential to be developed as an effective natural antimicrobial agent.

This study aimed to evaluate the effect of broiler concentrate-based rations combined with corn and rice bran on the performance of native chickens. A total of four dietary treatments were formulated, namely P1 (100% broiler concentrate), P2 (75% broiler concentrate, 10% corn, 15% rice bran), P3 (50% broiler concentrate, 30% corn, 20% rice bran), and P4 (25% broiler concentrate, 55% corn, 20% rice bran). The parameters observed included feed intake, body weight gain, and feed conversion ratio (FCR). Data were analyzed using analysis of variance (ANOVA), and significant differences among treatments were further tested with Duncan’s New Multiple Range Test (DMRT). The results showed that dietary treatments significantly affected the growth performance of native chickens (P<0.05). Chickens fed diets with higher proportions of broiler concentrate (P1 and P2) exhibited better body weight gain and more efficient feed conversion compared to those receiving lower concentrate levels (P3 and P4). In contrast, increasing corn and rice bran levels tended to increase feed intake but did not proportionally improve body weight gain, resulting in poorer FCR. It can be concluded that native chickens perform optimally when fed rations containing at least 75% broiler concentrate, which provides a balance between growth and feed efficiency.

Al–Mg–Si aluminum alloys are widely utilized in engineering applications due to their low density, excellent corrosion resistance, and mechanical properties that can be modified through heat treatment. This study investigates the effect of homogenization on the microstructure and hardness of Al–Mg–Si alloys produced by the squeeze casting process. The experimental procedure involved alloy melting, squeeze casting at 76 MPa using preheated metal molds, followed by homogenization at 400 °C for 4 hours. Microstructural characterization was performed using optical microscopy to examine the dendritic morphology and measure the secondary dendrite arm spacing (SDAS). Mechanical properties were evaluated through Vickers microhardness and Rockwell macrohardness testing. The results show that homogenization increases the SDAS from 32.59 μm to 36.88 μm and decreases the volume fraction of interdendritic phases from 15.51% to 13.57%. Furthermore, microhardness decreased from 50.22 VHN to 38.58 VHN, while macrohardness decreased from 54.60 HRE to 46.64 HRE. These reductions are attributed to the partial dissolution of Mg₂Si precipitates into the aluminum matrix during homogenization. Overall, this research provides valuable insight into the optimization of initial heat treatment parameters for Al–Mg–Si alloys produced by squeeze casting. The findings highlight the role of homogenization in improving microstructural uniformity and preparing the alloy for subsequent deformation processes such as cold rolling and extrusion, particularly for structural components used in mining and heavy transportation industries.

Legal uncertainty in the implementation of the carbon tax poses significant challenges to Indonesia’s investment climate, particularly in the non-renewable energy sector. This study aims to examine how the postponement of carbon tax implementation, despite the operation of carbon trading instruments, affects foreign investors’ expectations from the perspective of investment law. The research employs a normative juridical (dogmatic) approach combined with a light event study on major policy milestones between 2021 and 2023, including Presidential Regulation No. 98/2021, Ministerial Regulation of Energy and Mineral Resources No. 16/2022, OJK Regulation No. 14/2023, the launch of IDXCarbon, and the announcement of the carbon tax delay until 2025. The findings reveal varied market responses in fossil-based utility firms’ stocks and bonds, indicating the presence of an uncertainty premium. From a legal standpoint, the asymmetric configuration between delayed fiscal instruments and the ongoing non-fiscal instruments potentially undermines the principle of legal certainty under Investment Law No. 25/2007, while also raising risks related to Fair and Equitable Treatment (FET) and legitimate expectations. Nevertheless, the state’s right to regulate remains a crucial foundation for balancing investor protection with the imperative of energy transition. This study underscores the importance of policy consistency and transparency to maintain investment attractiveness and strengthen the legitimacy of Indonesia’s climate regulation.
